Why Mulch?
Agriculture with mulch in the tropics promotes plant health and vigor. Mulching improves nutrient and water retention in the soil, encourages favorable soil microbial activity and worms, and suppresses weed growth. When properly executed, mulching can significantly improve the well-being of plants and reduce maintenance as compared to bare soil culture. Mulched plants have better vigor and, consequently have improved resistance to pests and diseases.
"Mulch" is a layer of decaying organic matter on the ground. Mulch occurs naturally in all forests; it is a nutrient rich, moisture absorbent bed of decaying forest leaves, twigs and branches, teeming with fungal, microbial and insect life. Natural mulch serves as a "nutrient bank," storing the nutrients contained in organic matter and slowly making these nutrients available to plants. All forms of plant life from the ground layer to shrubs and trees thrive, grow, shed organic matter, die and decay, in a complicated cycle of nutrients.
Mulch forms a necessary link in nutrient cycling vital for our soils. When mulch is absent for whatever reason, the living soil is robbed of its natural nutrient stores, becomes leached and often desiccates. Natural environments without a litter layer are usually deserts. Non-desert plants grown in bare soil require constant fertilization, nutrient amendment and water, not to mention the work required to keep the soil bare.
Sheet mulching as described here is a suggested method for controlling weeds and improving soil and plant health with mulch. The process mimics the litter layer of a forest floor.
Basic Techniques of Sheet Mulching
Once you get the hang of it, sheet mulching can be used anywhere plants are grown in the ground. Sheet mulching may be used either in establishing a new garden or tree planting, or to enrich existing plantings. In both cases, mulch is applied to bare soil or on top of weeds. New plantings are planted through the mulch, and a small area is left open to accommodate established plants and trees.
The benefits of mulching justify putting the energy into doing the job right, using ample materials. Collect all of the materials (as outlined below), and complete the mulching process in a day. A reduction in maintenance and increase in plant vigor will reward the initial effort.
Sheet mulch is put down in layers to mimic natural forest mulch: well decayed compost, weed barrier, partly decayed compost and raw organic matter.
How to sheet mulch
Step 1: The Concentrated Compost Layer
To prepare the site, knock down tall weeds and woody plants with a brush cutter, scythe, or simply by trampling the area. Then proceed to lay down the sheet mulch.
Whether you are mulching bare soil or weeds, the first step is to "jump start" microbial activity by adding enriched compost, poultry or stock manure, worm castings or the like at the rate of about 50 lbs/100 square feet. This high nitrogen matter stimulates soil life and gets things going. If the soil is acid, which it likely is if the area has been disturbed recently and treated with conventional fertilizers, add a layer of lime or crushed coral. A soil analysis will indicate the need for adjustment of pH or mineral amendments. This is the appropriate time to add the recommended doses of amendments such as rock phosphate and K mag.
Soak the area well with water when the amendments are dispersed.
Step 2: The Weed Barrier
Most cultivated areas today harbor untold numbers of weed seeds. There are also weed seeds carried around by wind, animals and people. Soil borne seeds are lying dormant and waiting for the right conditions to sprout. Simply pulling or killing growing weeds will not erase the weed problem: more seeds will sprout almost as soon as the soil is exposed to moisture and light. Therefore the next step in mulching is to put down an organic weed barrier. This barrier prevents the germination and eventual emergence of weeds through your mulch.
Underneath this weed barrier grasses and weeds die and quickly become food for earthworms. From now on, the worms turn and aerate the soil, as they do naturally when in the right environment.
Of the four sheet mulch layers, the weed barrier has no natural counterpart on the forest floor. In the forest, weeds do not sprout because there is "no room for them," which simply means a lack of space above and below the ground, and a lack of light. By planting an area properly, there will eventually be no room for weeds. The weed barrier is needed only for establishment of the mulch, and disappears with time. If your area is planted appropriately, weeds will not emerge after the decomposition of the weed barrier.
Materials for the weed barrier that work well are: 4-6 sheets of newspaper, cardboard, burlap bags, old rugs of natural fiber, worn-out jeans, gypsum board, or whatever you can find around. Banana, ape and ti leaves also work if laid down in several layers. Overlap the pieces of the material so as to completely cover the ground without any breaks, except where there are plants you want to save. Around these leave a generous opening for air circulation around the root crown. Care in laying down the weed barrier will save you the headache of emerging weeds later on.
Step 3: The Compost Layer
This layer is on top of the weed barrier - it must be weed seed free. Well conditioned compost, grass clippings, seaweed and leaves are ideal materials to spread over the weed barrier. Any weed-free material mixture at the right moisture level for a good compost will do. This should form a fairly dense layer about 3 inches thick.
Step 4: The Top Layer
The top dressing mimics the newly fallen organic matter of the forest. It also must be weed-free. Good materials for this include leaves, twigs and small branches, fern or palm fronds, straw, coffee chaff, macadamia nut shells, wood chips, sawdust, bark, etc.. The top layer will slowly decompose into lower layers, and therefore must be replaced periodically; it represents reserves of compost. This layer should be about 3-5 inches deep. Many materials suitable for the top layer often have a pleasant cosmetic appearance. What luck! For this reason, there should be no hesitation in using sheet mulch in all cultivation from landscaping to gardening to permanent orchard crops. In fact, as you use mulch, bare soil will begin to seem ugly and undesirable.
When the soil is amended and sheet mulch applied properly, there will never be a need to turn the soil. Earthworms do the tilling. The only task left will be to keep the soil covered by replenishing the mulch.
Warning: Feral pigs love good, moist soil, and will grub in sheet mulch if they have access to it. Do not use sheet mulch if pigs have access to the area; they will be attracted to it and will destroy both your work and your plantings.
Mulching Around Trees
1) Plant tree.
2) Amend soil around tree in a wide ring shape from a few centimeters from trunk out to 1 meter (3 feet) with a light layer of nitrogen fertilizer, such as chicken manure, and other amendments if necessary. Rake or water in.
3) Spread a layer of permeable weed barrier around the tree in a ring shape, leaving about 15 cm (6 inches) diameter around the trunk of the tree for it to "breathe." Make certain there are no gaps in the ring shape through which weeds can emerge. Water the weed barrier layer thoroughly before the next step.
4) Spread compost and/or mulch about 15 cm (6 inches) thick over the weed barrier, again making sure it is several centimeters away from the trunk of the plant.
The Ongoing Process
To make mulching as efficient and easy as possible, use mulch materials which are readily available. With good planning, mulching of gardens and orchards can become a regular part of maintenance-just mulch with handy materials such as grass clippings, plant prunings (chipped or roughly chopped), animal bedding, etc.. Eventually, other tasks such as watering, fertilization and weeding will be reduced. The overall maintenance burden in mulched conditions, when properly executed, is far less than in conventional systems.
Once a plant is properly mulched, its own leaf drop will constantly add to that mulch. But is natural leaf drop enough to maintain the mulch? The answer to this depends on the plant species and also how the plant is growing in relation to other plants. Certain trees produce tremendous amounts of leaf matter which decomposes rather slowly; examples are: avocado, macadamia, lychee, as well as many others. These trees can be expected to generate sufficient mulch for themselves once vigorous growth is attained. Unfortunately, under most conditions many trees do not create enough long lasting mulch for maintenance of their needs. To explain this apparent deficiency, look once again at the forest. Here, plants are "stacked" in the vertical direction in ground-level, middle, and tall vegetation. This means that the ground under each plant receives organic matter from several plants.
There are many ways to produce sufficient mulch at your site. Grass clippings, for example, represent nutrient rich mulch material. Deep rooted, vigorous growing plants that readily come back from hard pruning or coppicing will also work. There are several nitrogen fixing trees which produce copious amounts of green matter. Each should be evaluated for the specific site before planting. Other plants that work well are kukui, hau, desmodium,, various bunch grasses (such as Guinea grass), lemon grass, comfrey, etc.. Also, many water plants such as water hyacinth are good mulch materials. Since plants that produce heavy amounts of organic matter are by their nature nearly irrepressible, extreme caution should be taken not to let these plants escape your management and become weedy.
Sheet mulching should not be confused with composting, artificial weed barriers, or green manuring. Sheet mulching as described here is quite different from these in that it seeks to recreate the organic mulch layer of the forest with a minimum of effort from people. Properly planned, a backyard or orchard system will produce its own raw mulch in sufficient amounts and people are involved only in putting this material back onto the ground where it belongs.

Please take a few minutes to wade through the following 9 paragraphs and see if you can come out the other side with a better understanding of how we could be living here on Earth, even with a collapsing biosphere.
Have we run out of room on... this planet? There are those who believe we have reached the overpopulation point. There is plenty of hard evidence that we may have done so: crammed cities, rampant poverty in rural as well as urban areas, malnourished people spread all over the less developed parts of the world, the whole situation complicated by any number of extreme weather events: drought, flood, wind storms, earthquakes, etc. and human caused environmental degradation, soil depletion, and more. It is becoming increasingly hard to provide the masses of humanity with clean water, nutritious food, waste treatment, and, in high pollution zones, fresh air to breathe.
The true picture is not pretty, especially if one looks at the poorest places on the planet. Climate change is going to complicate matters even further with an increase in unpredictable and extreme weather events including a steady rise in worldwide sea levels and the submergence of highly populated lowlands. Inland aquifers are being sucked dry after being poisoned by agricultural chemicals and industrial toxins. Deserts are expanding. Wars are proliferating. Oil is becoming more rare and expensive. We’re running out of power. Given the current data, prospects for a peaceful and abundant future do not look too good unless you are one of the few wealthy elite with the means to pay any price to purchase the remaining resources.
It doesn’t have to be this way. The future does not have to be grim. We do not have to scramble for scraps if we create a practical and affordable solution for dealing with the very real problems we actually face. Most thinking people know how bad it already is and can imagine how bad it might become if we do not change course and quickly. What is this course change? That’s the real question. Does it have something to do with massive population reduction and a return to some sort of primitive existence? Should we attempt a mass migration to Mars? The answer is much simpler than that. We need to recycle everything.
There is plenty of matter available on Earth to make life support miracles happen. The trick is in how we manipulate and shape it and for what purpose. Guns will not keep anyone alive if there is nothing left to hunt. I wouldn’t make more of those. Cell phones can be great communication devices yet I wouldn’t try eating one. I’d much rather step into a high intensity food production greenhouse and chomp down on a carrot than attempt to feed on sawdust and old shoe leather. Get my point? We need to make something new which can get us out of this mess.
The greenhouse is good. It’s part of the solution. Tweek it up a bit and that greenhouse can do more than provide food. It can turn dirty water clean, eliminate organic wastes, and provide fresh oxygen-rich air. Wouldn’t that be nice? Rich people might not care because they already have those things in abundance. Poor people are in dire need and the dwindling middle class is close on their heals. Whatever the economic case, remember this word: CELSS (Closed Ecological Life Support System). It is a NASA-derived term for a biological based machine which could keep a colony alive on Mars. I think CELSS has direct application here on Earth as well. We have a lot of people in dire need of sustainable life support.
I actually believe there is more than enough room on this planet for the current population, even an increase, if we employ CELSS to process our stale air, wash water, and organic wastes, using these “natural resources” in conjunction with nature and natural processes to provide us with the essentials of life. In fact, if we have a mind to, we can build life-supporting CELSS out of recycled materials, or mass manufacture them in every style from the developing world economy model to the middle class add-on edition. Custom jobs could be done for the rich and famous.
There is a nice side effect from employing CELSS. Once people start using them on a regular basis, they stop polluting and otherwise disrupting the surrounding environment which then regenerates! Yes, nature has a few tricks up her sleeve. She can perform them if we aid her in the process. The first thing we need to do to help the situation is to stop using Mother Earth like she was our personal milk mom. Aren’t we’re supposed to be adults here? The mark of a mature person is their ability to care for their needs without having to run home to mommy‘s breasts. If I was an ambassador from the Intergalactic Federation sent to Earth to determine whether or not humankind had an advanced enough civilization to merit official entrance into the Federation, I would have to say, “Not yet. They still haven’t learned how to grow up and care for themselves”. We could do so.
“We will transform the Earth from the garbage pit of civilization into its rightful place as the breadbasket of the solar system, plant propagator, green machine, exporter of fine food to the Moon, Mars, and world’s beyond.” - the Alchemist
The task before us is to design and construct small scale “closed loop” ecosystems which are capable of supplying all our basic life support needs on Earth. Advanced versions can be sent to the Moon or Mars once we’ve field tested and perfected CELSS. For now, I would be happy to have one in my yard. Just think of the food, water, and sanitation bills I wouldn’t have to pay! Now, don’t get me wrong. If you love to garden outdoors, by all means continue to do so. Mother Earth loves to be cared for. I’m not talking about having to live sealed in a bubble. Yet, wouldn’t it be nice if your home was outputting oxygen, food, and clean water while you were outside taking it all in? Instead of sucking it all up we could be putting back more than we consume. That is a mark of a highly advanced civilization worthy of Federation membership.
Can you help? We’re not asking for money. Most of all, we need your accumulated knowledge and research capabilities. There are many questions on the particulars of CELSS operations. I’ve built a couple of human scale CELSS-tech “test beds” to see for myself what works and does not. I’ve studied the literature, read the science papers, discussed the details with other researchers, lectured on the topic, presented my own papers, and am now asking if you would like to be involved in the process of perfecting CELSS. There is a whole planet in need of upgrading. It helps if we are working together cooperatively.
More information can be found in this group: http://groups.yahoo.com/gr
CELSS (Closed Ecological Life Support System) is a “living machine” which, ideally, provides it’s inhabitant(s) with 100% of their life support (organic food, fresh oxygen-rich air, clean water) by recycling the waste p...roducts generated by the inhabitant(s) and by the CELSS itself. We call that “closing the loop”. As it has been said, “the devil is in the details”. CELSS is relatively new in the world. Now, of course, the planet-wide life supporting biosphere it a large scale CELSS. By studying what nature does to recycle we may apply these principles on a much smaller personalized scale. It helps to design for the worst possible scenario in the harshest environments (like Mars) and then it becomes easier and simpler to build robust systems for kinder climates. So, to start, imagine we have landed on a barren planet with no air, water, or food to eat except what we brought with us. Here’s what we have to work with (this can get gross):
MATERIAL INPUTS
1) HUMAN BODY: feces, urine, farts, belches, vomit, snot, spit/saliva, phlegm, sweat, tears, earwax, milk, sperm/semen, smegma, menstrual blood, blood, pus, nail clippings, hair, dead skin, water vapor, CO2, trace gasses, heat, medicine residues, and (if someone dies) dead bodies and body parts
2) PLANTS: unused biomass, garbage, plant oils, O2, CO2, ethylene and other trace gasses, water vapor
3) ANIMALS: much the same as what humans output
4) MATERIALS & PROCESSES: oils, soaps, worn out clothing (composed of natural fibers/dyes only), laundry & wash (gray) water, out-gassings (solvents/trace gasses from materials used in the CELSS shell construction and other items inside the CELSS).
That’s what we have to work with in the “hermetically sealed version“. Of course, on Earth or anywhere there are some useful outside resources, our task would be easier. Yet, if we design the hermetically sealed version, I‘m sure, on the way to the final design, we will cover just about any condition or environment we can imagine. While we are brainstorming this “ultimate CELSS” we need to be aware of the amount of energy required to make the whole thing work. The less energy required the better. Also, technologically complex systems tend to break down faster than simple systems. We adhere to the engineering principle of KISS (Keep It Simple Stupid). We don’t want to design anything which requires a lot of repairs, maintenance, or spare parts. The number of human hours spent per day keeping the system fully operational should also be considered. We’re not into this to work ourselves to death. We shouldn’t have to spend more than a hour or so a day doing our chores in an optimal system. Remember, we’re on a planet’s surface so we have gravity on our side. In space we would have to spin the whole thing to simulate gravity. For now, let’s stay grounded and focused on the transformations.
The MATERIAL INPUTS listed above must be transformed into the following:
1) nutrient rich water and soil for plants, fungi, and symbiotic micro-organisms
2) CO2 and trace gas-rich air for the plants, fungi, and symbiotic micro-organisms
3) clean water for humans and animals
4) oxygen rich air with few trace gasses (ethylene, methane, carbon monoxide, and other exotics) for humans and animals
5) continuously and regularly producing organic food supply for humans and animals
Get the picture? What goes around comes around. There is a dynamic relationship between humans, animals, plants, fungi, and symbiotic micro-organisms. What we are trying to do is optimize this relationship by building containment vessels which provide optimal conditions for each of the above. We want to make everyone and everything involved very comfortable and in a state of being nurtured at all times. We also want to do this in a way which prevents pathogens from thriving. We’re aiming for a high oxygen level (aerobic) conditions throughout the CELSS. Anaerobic conditions (such as found in septic systems) are to be avoided because they breed disease and poisonous gasses like hydrogen sulfide (rotten egg odor) and methane. Plants out-gas ethylene which is, at certain concentrations, a growth inhibitor for the plants. It too needs to be converted or a hermetically sealed system will die.
How large should a fully operational CELSS be? As small as possible and small is possible. Here are some optimistic figures from the CELSS life support research community:
ESTIMATED GROW SPACE REQUIRED PER PERSON
(may be stacked into multiple levels for more efficient operation)
14 m2 - Gitalson
56 m2 - Bios3
20-30 m2 - Cullingford & Schwatekopf
13-50 m2 - Bugsbee & Salisbury
56.9 m2 - Oleson & Olson
8-20 m2 - MacElroy & Averner
15-20 m2 - Eckhart
24 m2 - Hoff
15 m2 - Vasilyew
As you can see, the above figures are tiny compared to the amount of space the average human being requires for life support in both hunter/gatherer and agriculture-based civilizations. Since the Earth’s “carrying capacity” is already exceeded because of the rapidly expanding human population, anything we do to reduce an individual’s “footprint” (space/resource required to keep a person alive) is a step in the correct direction. Lab work (NASA Ames) has already proven that all the air, water, and food for one person can be grown in a 16’ x 16’ space under optimal conditions with controlled atmosphere, temperature, lighting, and nutrients. Of course this was a highly engineered “hydroponics” style system which required considerable electricity for the lighting, pumps, and climate control plus an outside source of plant nutrients. So, it cannot really be called a CELSS but it sure is an encouraging experiment. I bet we can do pretty good together too!
That’s enough for the moment. Read through the above a few times and start dreaming of how you might turn each of the MATERIAL INPUTS into what we need to get in return. If you have any ideals fleshed ot in some detail, please share them with the group. My job here is to facilitate the “think tanking” and keep us on course to building a functioning CELSS. I’m going to be poking and prodding so don’t take it personally when I question you input or put a new twist into the puzzle. Doing so is part of my job facilitating this group. One thing I’m going to be stressing is INTEGRATING FUNCTIONS. If one piece of hardware can do 3 things simultaneously, I’m probably going to suggest it.

The Soy and Other 'Natural' Food Products in Your Cabinet May Contain a Dangerous Neurotoxin | | AlterNet
It's ironic that many of the scariest, non-certified organic foods are labeled "natural" -- a term that could not mean less, or mislead more. Like "home-style" or "old-fashioned," the label "natural" can mean whatever the labeler wants it to mean. You could put "natural" on a lab-grade jar of MSG crystals, or on a packet of 10-year-old Twinkies, without violating any law. And all too often it's the companies playing the "natural" card that are doing the most unnatural things to your food.
Consider the widespread use of hexane, a neurotoxin, in processed foods that aren't certified organic (those lame organic standards do at least prohibit hexane use). Hexane is a highly flammable EPA-listed air pollutant that is used in the manufacture of cleaning agents, glues, roof sealer, automobile tires, energy bars, veggie burgers, and soy, corn, and canola oils. If these food products are not certified organic, some of the ingredients have probably been processed with hexane, no matter how many times the word "natural" is stamped on the package. Since hexane is used in the manufacturing process, it's not listed as an ingredient in the foods it helps produce, though residues find their way into the finished product. The European Union has strict standards for acceptable hexane residue levels in soy and oilseed products, but in the U.S., there are no such limits.
The organic watchdog group Cornucopia Institute arranged for a lab to test samples of U.S. soy products for hexane content. Hexane was found, in levels as high as 21 parts per million -- more than twice the 10 ppm allowed by the EU in comparable products.
Technology and Solvents for Extracting Oilseeds and Nonpetroleum Oils is a manual for managers and engineers. According to this book, published in 1997, the principle reason that hexane has been the solvent of choice for oilseed extraction since the 1930s is "its availability at a reasonable cost."
The reason hexane is so reasonably priced is that it's a byproduct of gasoline production that would otherwise be expensive to dispose of properly. Petroleum companies gain handsomely from the fact that industrial oilseed extraction -- under status quo production methods since the 1930s -- provides a profitable market for its toxic waste. Oilseed extraction is currently responsible for more than two thirds of hexane use nationwide. Not surprisingly, much of the research cited in the book is funded by the likes of Exxon and Phillips Petroleum.

Fluorine Poison Is Rampant in Pharmaceuticals
Fluorine Poison Is Rampant in Pharmaceuticals
Fluorine is a poison with no place in any living metabolism. Yet, it's commonplace in pharmaceuticals. (Includes a list of drugs with fluorine.)
by Heidi Stevenson
27 December 2010
Fluorine is a poison. It has no place in the metabolism of humans, animals, or plants. It destroys bones and teeth, and wreaks havoc on all body systems. Fluorine is one of the most pervasive elements in pharmaceutical drugs.
Modern drug-based medicine depends on fluorine. Early symptoms of poisoning are generally not recognized, as they are commonly experienced. These can include excess salivation, nausea, vomiting, diarrhea, and abdominal pain. One must wonder how many people believe they have flu when they're actually suffering from fluorine poisoning.
These symptoms are insidious because they can indicate the beginnings of severe metabolic disorders that lead to endocrinological diseases, such as hypocalcemia, hypomagnesemia, hyperkalemia, and hypoglycemia. These conditions can have knock-on effects throughout the body in chronic disorders. Subclinical imbalances in any of these necessary substances—calcium, magnesium, potassium, and sugar—can result in long term and permanent harm.
Fluorine poisoning can also result in neurological damage, including headaches, tremors, spasms, tetanic contractions, hyperactive reflexes, seizures, and muscle weakness. Ultimately, it causes teratogenic disorders—birth defects of the worst sort.
It is, in fact, fluorine that makes dioxins so horrific. (For information about dioxin poisoning in the United States, along with a photo gallery of deformities that its incarnation as Agent Orange in Vietnam unleashed and its effects on children in England, go here.
Cardiovascular involvement can result in widening of QRS (abnormality in heartbeat that can result in sudden death), arrhythmias, shock, and cardiac arrest.
Many common, and many infamous, drugs contain fluorine: Prozac, the first SSRI. Flonase, decongestant. Lipitor and Baycol, cholesterol reducers. Diflucan, antifungal drug. Cipro, antibiotic. Prevacid and Propulsid, antacids. This list goes on...and on and on.
Ingesting a drug with fluorine is a risky act. You might think that special warnings would be placed on drugs compounded with fluorine, but none is.
To help you protect yourself, here's a list of most of the fluorine-based drugs, broken down by their typical use. The list is by generic name. Let the pointer hover over a name with a dotted underline to see a display of names under which the drug is sold. If the drug has been removed from the market, the year is added in parentheses.
Drugs That Contain Fluorine

Deadly Medicine
Prescription drugs kill some 200,000 Americans every year. Will that number go up, now that most clinical trials are conducted overseas—on sick Russians, homeless Poles, and slum-dwelling Chinese—in places where regulation is virtually nonexistent, the F.D.A. doesn’t reach, and “mistakes” can end up in pauper’s graves? The authors investigate the globalization of the pharmaceutical industry, and the U.S. Government’s failure to rein in a lethal profit machine.
You wouldn’t think the cities had much in common. IaÅŸi, with a population of 320,000, lies in the Moldavian region of Romania. Mégrine is a town of 24,000 in northern Tunisia, on the Mediterranean Sea. Tartu, Estonia, with a population of 100,000, is the oldest city in the Baltic States; it is sometimes called “the Athens on the Emajõgi.” Shenyang, in northeastern China, is a major industrial center and transportation hub with a population of 7.2 million.
These places are not on anyone’s Top 10 list of travel destinations. But the advance scouts of the pharmaceutical industry have visited all of them, and scores of similar cities and towns, large and small, in far-flung corners of the planet. They have gone there to find people willing to undergo clinical trials for new drugs, and thereby help persuade the U.S. Food and Drug Administration to declare the drugs safe and effective for Americans. It’s the next big step in globalization, and there’s good reason to wish that it weren’t.
Once upon a time, the drugs Americans took to treat chronic diseases, clear up infections, improve their state of mind, and enhance their sexual vitality were tested primarily either in the United States (the vast majority of cases) or in Europe. No longer. As recently as 1990, according to the inspector general of the Department of Health and Human Services, a mere 271 trials were being conducted in foreign countries of drugs intended for American use. By 2008, the number had risen to 6,485—an increase of more than 2,000 percent. A database being compiled by the National Institutes of Health has identified 58,788 such trials in 173 countries outside the United States since 2000. In 2008 alone, according to the inspector general’s report, 80 percent of the applications submitted to the F.D.A. for new drugs contained data from foreign clinical trials. Increasingly, companies are doing 100 percent of their testing offshore. The inspector general found that the 20 largest U.S.-based pharmaceutical companies now conducted “one-third of their clinical trials exclusively at foreign sites.” All of this is taking place when more drugs than ever—some 2,900 different drugs for some 4,600 different conditions—are undergoing clinical testing and vying to come to market.
Some medical researchers question whether the results of clinical trials conducted in certain other countries are relevant to Americans in the first place. They point out that people in impoverished parts of the world, for a variety of reasons, may metabolize drugs differently from the way Americans do. They note that the prevailing diseases in other countries, such as malaria and tuberculosis, can skew the outcome of clinical trials. But from the point of view of the drug companies, it’s easy to see why moving clinical trials overseas is so appealing. For one thing, it’s cheaper to run trials in places where the local population survives on only a few dollars a day. It’s also easier to recruit patients, who often believe they are being treated for a disease rather than, as may be the case, just getting a placebo as part of an experiment. And it’s easier to find what the industry calls “drug-naïve” patients: people who are not being treated for any disease and are not currently taking any drugs, and indeed may never have taken any—the sort of people who will almost certainly yield better test results. (For some subjects overseas, participation in a clinical trial may be their first significant exposure to a doctor.) Regulations in many foreign countries are also less stringent, if there are any regulations at all. The risk of litigation is negligible, in some places nonexistent. Ethical concerns are a figure of speech. Finally—a significant plus for the drug companies—the F.D.A. does so little monitoring that the companies can pretty much do and say what they want.
Consent by Thumbprint
Many of today’s trials still take place in developed countries, such as Britain, Italy, and Japan. But thousands are taking place in countries with large concentrations of poor, often illiterate people, who in some cases sign consent forms with a thumbprint, or scratch an “X.” Bangladesh has been home to 76 clinical trials. There have been clinical trials in Malawi (61), the Russian Federation (1,513), Romania (876), Thailand (786), Ukraine (589), Kazakhstan (15), Peru (494), Iran (292), Turkey (716), and Uganda (132). Throw a dart at a world map and you are unlikely to hit a spot that has escaped the attention of those who scout out locations for the pharmaceutical industry.
The two destinations that one day will eclipse all the others, including Europe and the United States, are China (with 1,861 trials) and India (with 1,457). A few years ago, India was home to more American drug trials than China was, thanks in part to its large English-speaking population. But that has changed. English is now mandatory in China’s elementary schools, and, owing to its population edge, China now has more people who speak English than India does.
While Americans may be unfamiliar with the names of foreign cities where clinical trials have been conducted, many of the drugs being tested are staples of their medicine cabinets. One example is Celebrex, a non-steroidal anti-inflammatory drug that has been aggressively promoted in television commercials for a decade. Its manufacturer, Pfizer, the world’s largest drug company, has spent more than a billion dollars promoting its use as a pain remedy for arthritis and other conditions, including menstrual cramps. The National Institutes of Health maintains a record of most—but by no means all—drug trials inside and outside the United States. The database counts 290 studies involving Celebrex. Companies are not required to report—and do not report—all studies conducted overseas. According to the database, of the 290 trials for Celebrex, 183 took place in the United States, meaning, one would assume, that 107 took place in other countries. But an informal, country-by-country accounting by VANITY FAIR turned up no fewer than 207 Celebrex trials in at least 36 other countries. They ranged from 1 each in Estonia, Croatia, and Lithuania to 6 each in Costa Rica, Colombia, and Russia, to 8 in Mexico, 9 in China, and 10 in Brazil. But even these numbers understate the extent of the foreign trials. For example, the database lists five Celebrex trials in Ukraine, but just “one” of those trials involved studies in 11 different Ukrainian cities.
The Celebrex story does not have a happy ending. First, it was disclosed that patients taking the drug were more likely to suffer heart attacks and strokes than those who took older and cheaper painkillers. Then it was alleged that Pfizer had suppressed a study calling attention to these very problems. (The company denied that the study was undisclosed and insisted that it “acted responsibly in sharing this information in a timely manner with the F.D.A.”) Soon afterward the Journal of the Royal Society of Medicine reported an array of additional negative findings. Meanwhile, Pfizer was promoting Celebrex for use with Alzheimer’s patients, holding out the possibility that the drug would slow the progression of dementia. It didn’t. Sales of Celebrex reached $3.3 billion in 2004, and then began to quickly drop.
“Rescue Countries”
One big factor in the shift of clinical trials to foreign countries is a loophole in F.D.A. regulations: if studies in the United States suggest that a drug has no benefit, trials from abroad can often be used in their stead to secure F.D.A. approval. There’s even a term for countries that have shown themselves to be especially amenable when drug companies need positive data fast: they’re called “rescue countries.” Rescue countries came to the aid of Ketek, the first of a new generation of widely heralded antibiotics to treat respiratory-tract infections. Ketek was developed in the 1990s by Aventis Pharmaceuticals, now Sanofi-Aventis. In 2004—on April Fools’ Day, as it happens—the F.D.A. certified Ketek as safe and effective. The F.D.A.’s decision was based heavily on the results of studies in Hungary, Morocco, Tunisia, and Turkey.
The approval came less than one month after a researcher in the United States was sentenced to 57 months in prison for falsifying her own Ketek data. Dr. Anne Kirkman-Campbell, of Gadsden, Alabama, seemingly never met a person she couldn’t sign up to participate in a drug trial. She enrolled more than 400 volunteers, about 1 percent of the town’s adult population, including her entire office staff. In return, she collected $400 a head from Sanofi-Aventis. It later came to light that the data from at least 91 percent of her patients was falsified. (Kirkman-Campbell was not the only troublesome Aventis researcher. Another physician, in charge of the third-largest Ketek trial site, was addicted to cocaine. The same month his data was submitted to the F.D.A. he was arrested while holding his wife hostage at gunpoint.) Nonetheless, on the basis of overseas trials, Ketek won approval.
As the months ticked by, and the number of people taking the drug climbed steadily, the F.D.A. began to get reports of adverse reactions, including serious liver damage that sometimes led to death. The F.D.A.’s leadership remained steadfast in its support of the drug, but criticism by the agency’s own researchers eventually leaked out (a very rare occurrence in this close-knit, buttoned-up world). The critics were especially concerned about an ongoing trial in which 4,000 infants and children, some as young as six months, were recruited in more than a dozen countries for an experiment to assess Ketek’s effectiveness in treating ear infections and tonsillitis. The trial had been sanctioned over the objections of the F.D.A.’s own reviewers. One of them argued that the trial never should have been allowed to take place—that it was “inappropriate and unethical because it exposed children to harm without evidence of benefits.” In 2006, after inquiries from Congress, the F.D.A. asked Sanofi-Aventis to halt the trial. Less than a year later, one day before the start of a congressional hearing on the F.D.A.’s approval of the drug, the agency suddenly slapped a so-called black-box warning on the label of Ketek, restricting its use. (A black-box warning is the most serious step the F.D.A. can take short of removing a drug from the market.) By then the F.D.A. had received 93 reports of severe adverse reactions to Ketek, resulting in 12 deaths.
During the congressional hearings, lawmakers heard from former F.D.A. scientists who had criticized their agency’s oversight of the Ketek trials and the drug-approval process. One was Dr. David Ross, who had been the F.D.A.’s chief reviewer of new drugs for 10 years, and was now the national director of clinical public-health programs for the U.S. Department of Veterans Affairs. When he explained his objections, he offered a litany of reasons that could be applied to any number of other drugs: “Because F.D.A. broke its own rules and allowed Ketek on the market. Because dozens of patients have died or suffered needlessly. Because F.D.A. allowed Ketek’s maker to experiment with it on children over reviewers’ protests. Because F.D.A. ignored warnings about fraud. And because F.D.A. used data it knew were false to reassure the public about Ketek’s safety.”
Trials and Error
To have an effective regulatory system you need a clear chain of command—you need to know who is responsible to whom, all the way up and down the line. There is no effective chain of command in modern American drug testing. Around the time that drugmakers began shifting clinical trials abroad, in the 1990s, they also began to contract out all phases of development and testing, putting them in the hands of for-profit companies. It used to be that clinical trials were done mostly by academic researchers in universities and teaching hospitals, a system that, however imperfect, generally entailed certain minimum standards. The free market has changed all that. Today it is mainly independent contractors who recruit potential patients both in the U.S. and—increasingly—overseas. They devise the rules for the clinical trials, conduct the trials themselves, prepare reports on the results, ghostwrite technical articles for medical journals, and create promotional campaigns. The people doing the work on the front lines are not independent scientists. They are wage-earning technicians who are paid to gather a certain number of human beings; sometimes sequester and feed them; administer certain chemical inputs; and collect samples of urine and blood at regular intervals. The work looks like agribusiness, not research.
What began as a mom-and-pop operation has grown into a vast army of formal “contract-research organizations” that generate annual revenue of $20 billion. They can be found conducting trials in every part of the world. By far the largest is Quintiles Transnational, based in Durham, North Carolina. It offers the services of 23,000 employees in 60 countries, and claims that it has “helped develop or commercialize all of the top 30 best-selling drugs.”
Quintiles is privately owned—its investors include two of the U.S.’s top private-equity firms. Other private contractors are public companies, their stock traded on Wall Street. Pharmaceutical Product Development (P.P.D.), a full-service medical contractor based in Wilmington, North Carolina, is a public company with 10,500 employees. It, too, has conducted clinical trials all around the world. In fact, it was involved in the clinical trials for Ketek—a P.P.D. research associate, Ann Marie Cisneros, had been assigned to monitor Dr. Anne Kirkman-Campbell’s testing in Alabama. Cisneros later told the congressional investigating committee that Kirkman-Campbell had indeed engaged in fraud. “But what the court that sentenced her did not know,” Cisneros said, was that “Aventis was not a victim of this fraud.” Cisneros said she had reported her findings of fraud to her employer, P.P.D., and also to Aventis. She told the congressional committee, “What brings me here today is my disbelief at Aventis’s statements that it did not know that fraud was being committed. Mr. Chairman, I knew it, P.P.D. knew it, and Aventis knew it.” Following her testimony the company released a statement saying it regretted the violations that occurred during the study but was not aware of the fraud until after the data was submitted to the F.D.A.
The F.D.A., the federal agency charged with oversight of the food and drugs that Americans consume, is rife with conflicts of interest. Doctors who insist the drug you take is perfectly safe may be collecting hundreds of thousands of dollars from the company selling the drug. (ProPublica, an independent, nonprofit news organization that is compiling an ongoing catalogue of pharmaceutical-company payments to physicians, has identified 17,000 doctors who have collected speaking and consulting fees, including nearly 400 who have received $100,000 or more since 2009.) Quite often, the F.D.A. never bothers to check for interlocking financial interests. In one study, the agency failed to document the financial interests of applicants in 31 percent of applications for new-drug approval. Even when the agency or the company knew of a potential conflict of interest, neither acted to guard against bias in the test results.
Because of the deference shown to drug companies by the F.D.A.—and also by Congress, which has failed to impose any meaningful regulation—there is no mandatory public record of the results of drug trials conducted in foreign countries. Nor is there any mandatory public oversight of ongoing trials. If one company were to test an experimental drug that killed more patients than it helped, and kept the results secret, another company might unknowingly repeat the same experiment years later, with the same results. Data is made available to the public on a purely voluntary basis. Its accuracy is unknown. The oversight that does exist often is shot through with the kinds of ethical conflicts that Wall Street would admire. The economic incentives for doctors in poor countries to heed the wishes of the drug companies are immense. An executive at a contract-research organization told the anthropologist Adriana Petryna, author of the book When Experiments Travel: “In Russia, a doctor makes two hundred dollars a month, and he is going to make five thousand dollars per Alzheimer’s patient” that he signs up. Even when the most flagrant conflicts are disclosed, penalties are minimal. In truth, the same situation exists in the United States. There’s just more of a chance here, though not a very large one, that adverse outcomes and tainted data will become public. When the pharmaceutical industry insists that its drugs have been tested overseas in accordance with F.D.A. standards, this may be true—but should provide little assurance.
The F.D.A. gets its information on foreign trials almost entirely from the companies themselves. It conducts little or no independent research. The investigators contracted by the pharmaceutical companies to manage clinical trials are left pretty much on their own. In 2008 the F.D.A. inspected just 1.9 percent of trial sites inside the United States to ensure that they were complying with basic standards. Outside the country, it inspected even fewer trial sites—seven-tenths of 1 percent. In 2008, the F.D.A. visited only 45 of the 6,485 locations where foreign drug trials were being conducted.
The pharmaceutical industry dismisses concerns about the reliability of clinical trials conducted in developing countries, but the potential dangers were driven home to Canadian researchers in 2007. While reviewing data from a clinical trial in Iran for a new heart drug, they discovered that many of the results were fraudulent. “It was bad, so bad we thought the data was not salvageable,” Dr. Gordon Guyatt, part of the research group at McMaster University in Hamilton, told Canada’s National Post.
In addition to monitoring trials abroad, which it does not really do, the F.D.A. is responsible for inspecting drug-manufacturing plants in other countries, which it also does not really do. In 2007 and 2008, hundreds of patients taking the blood thinner heparin, which among other purposes is used to prevent blood clots during surgery and dialysis, developed serious allergic reactions as a result of a contaminant introduced at a Chinese manufacturing facility. It took months for the F.D.A., its Chinese counterpart, and Baxter International, the pharmaceutical company that distributed the drug, to track the source of contamination to Changzhou, a city of 3.5 million on the Yangtze River.
The delay was perhaps understandable, given the manufacturing process. The raw material for Baxter’s heparin comes from China’s many small pig farms. To be precise, it’s derived from the mucous membranes of the intestines of slaughtered pigs; the membranes are mixed together and cooked, often in unregulated family workplaces. By the time the source of the contaminant was pinpointed, many more patients in the United States had experienced severe reactions, and as many as 200 had died. It later turned out that the F.D.A. had indeed inspected a Chinese plant—but it was the wrong one. The federal regulators had confused the names.
The good news was that, in this instance, the F.D.A. at least knew which country the heparin had come from. The bad news is that it does not always know where clinical trials are being conducted, or even the names or types of drugs being tested, or the purpose for which they will be prescribed once approved. Companies may withhold the foreign test data until they actually submit the application to the F.D.A. for approval. By then the agency has lost the ability to see whether the trials were managed according to acceptable standards, and whether the data collected was manipulated or fabricated.
$350 per Child
If the globalization of clinical trials for adult medications has drawn little attention, foreign trials for children’s drugs have attracted even less. The Argentinean province of Santiago del Estero, with a population of nearly a million, is one of the country’s poorest. In 2008 seven babies participating in drug testing in the province suffered what the U.S. clinical-trials community refers to as “an adverse event”: they died. The deaths occurred as the children took part in a medical trial to test the safety of a new vaccine, Synflorix, to prevent pneumonia, ear infections, and other pneumococcal diseases. Developed by GlaxoSmithKline, the world’s fourth-largest pharmaceutical company in terms of global prescription-drug sales, the new vaccine was intended to compete against an existing vaccine. In all, at least 14 infants enrolled in clinical trials for the drug died during the testing. Their parents, some illiterate, had their children signed up without understanding that they were taking part in an experiment. Local doctors who persuaded parents to enroll their babies in the trial reportedly received $350 per child. The two lead investigators contracted by Glaxo were fined by the Argentinean government. So was Glaxo, though the company maintained that the mortality rate of the children “did not exceed the rate in the regions and countries participating in the study.” No independent group conducted an investigation or performed autopsies. As it happens, the brother of the lead investigator in Santiago del Estero was the Argentinean provincial health minister.
In New Delhi, 49 babies died at the All India Institute of Medical Sciences while taking part in clinical trials over a 30-month period. They were given a variety of new drugs to treat everything from high blood pressure to chronic focal encephalitis, a brain inflammation that causes epileptic seizures and other neurological problems. The blood-pressure drugs had never before been given to anyone under 18. The editor of an Indian medical journal said it was obvious that the trials were intended to extend patent life in Western countries “with no consequence or benefit for India, using Indian children as guinea pigs.” In all, 4,142 children were enrolled in the studies, two-thirds of them less than one year old. But the head of the pediatrics department at the All India Institute maintained that “none of the deaths was due to the medication or interventions used in clinical trials.”
For years, American physicians gave anti-psychotic medicines to children “off label,” meaning that they wrote prescriptions based on testing for adults, sometimes even for different conditions. That didn’t work out so well for the children, who, when it comes to medicine, really are not just little adults. To provide the pharmaceutical industry with an incentive to conduct clinical trials on children’s versions of adult drugs, Congress in 1997 enacted legislation, known as the Pediatric Exclusivity Provision, extending the patent life of certain drugs by six months. It worked so well that the industry has, in the ensuing years, been able to put younger and younger children on more and more drugs, pocketing an extra $14 billion. Between 1999 and 2007, for instance, the use of anti-psychotic medications on children between the ages of two and five more than doubled.
A study of 174 trials under the Pediatric Exclusivity Provision found that 9 percent of them did not report the location or number of sites of the clinical trials. Of those that did, two-thirds had been conducted in at least one country outside the United States, and 11 percent were conducted entirely outside the United States. Of the 79 trials with more than 100 subjects participating, 87 percent enrolled patients outside the United States. As is the case with adult studies, many children’s trials conducted abroad are neither reported nor catalogued on any publicly accessible government database. There is no public record of their existence or their results.
In the mid-90s, Glaxo conducted clinical trials on the antidepressant Paxil in the United States, Europe, and South America. Paxil is a member of a class of drugs called selective serotonin re-uptake inhibitors. The class includes Zoloft, Prozac, and Lexapro. In the United Kingdom, Paxil is sold as Seroxat. The clinical trials showed that the drug had no beneficial effect on adolescents; some of the trials indicated that the placebo was more effective than the drug itself. But Glaxo neglected to share this information with consumers; annual sales of the drug had reached $5 billion in 2003. In an internal document obtained by the Canadian Medical Association Journal, the company emphasized how important it was to “effectively manage the dissemination of these data in order to minimize any potential negative commercial impact.” The memo went on to warn that “it would be commercially unacceptable to include a statement that efficacy had not been demonstrated.” After the document was released a Glaxo spokesperson said that the “memo draws an inappropriate conclusion and is not consistent with the facts.”
“Smoke and Mirrors”
It may be just a coincidence, but as controversy swirls around new drugs, and as the F.D.A. continues to slap medicines with new warning labels—especially the black-box warnings that indicate the most serious potential reactions—most of the problematic drugs have all undergone testing outside the United States. Clinical-trial representatives working for GlaxoSmithKline went to IaÅŸi, Romania, to test Avandia, a diabetes drug, on the local population. Glaxo representatives also showed up in other cities in Romania—BucureÅŸti, Cluj-Napoca, Craiova, and TimiÅŸoara—as well as multiple cities in Latvia, Ukraine, Slovakia, the Russian Federation, Poland, Hungary, Lithuania, Estonia, the Czech Republic, Bulgaria, Croatia, Greece, Belgium, the Netherlands, Germany, France, and the United Kingdom. That was for the largest of the Avandia clinical trials. But there have been scores of others, all seeking to prove that the drug is safe and effective. Some took place before the drug was approved by the F.D.A. Others were “post-marketing” studies, done after the fact, as the company cast about for ways to come up with more positive results so it could expand Avandia’s use for other treatments. Based on the initial evaluations, Avandia was expected to—and did—become another Glaxo multi-billion-dollar best-seller.
While sales soared, so, too, did reports of adverse reactions—everything from macular edema to liver injury, from bone fractures to congestive heart failure. In 2009 the Institute for Safe Medication Practices, a Pennsylvania-based nonprofit group that monitors the prescription-drug field, linked the deaths of 1,354 people to Avandia, based on reports filed with the F.D.A. Studies also concluded that people taking the drug had an increased risk of developing heart disease, one of the very conditions that doctors treating diabetics hope to forestall. The risk was so high that worried doctors inside and outside the F.D.A. sought to have the drug removed from the market, an incredibly difficult task no matter how problematic the medicine. As always, the F.D.A. was late to the party. In 2008 the American Diabetes Association and the European Association for the Study of Diabetes had warned against using Avandia. The Saudi Arabian drug-regulatory agency yanked it from the market, and the Indian government asked Glaxo to halt 19 of its Avandia trials in that country. In September 2010 the European Medicines Agency pulled Avandia from the shelves all across Europe. The F.D.A. still could not bring itself to take decisive action. This even though the F.D.A. knew that Glaxo had withheld critical safety information concerning the increased risk of heart attacks, and the F.D.A. itself had estimated that the drug had caused more than 83,000 heart attacks between 1999 and 2007. The agency settled for imposing new restrictions on the availability of the drug in the United States. Glaxo released a statement saying that it “continues to believe that Avandia is an important treatment for patients with type 2 diabetes,” but that it would “voluntarily cease promotion of Avandia in all the countries in which it operates.”
The Avandia case and others like it have prompted the U.S. Justice Department to mount an investigation under the Foreign Corrupt Practices Act. While it is legal for doctors in this country to accept money from drug companies for acting as consultants, this is not the case abroad, where doctors often are government employees, and such payments can be considered bribes. There are other legal issues. So far, Glaxo has paid out more than $1 billion to settle lawsuits arising from claims against Avandia and other drugs. The Senate Finance Committee calculates that, since May 2004, seven drug companies have paid out more than $7 billion in fines and penalties stemming from unlawful drug dealings. Pfizer paid the largest such fine in history—$2.3 billion for promoting off-label uses of the arthritis drug Bextra.
In theory, pharmaceutical companies are barred from selling a drug for any purpose other than the one that the F.D.A. has approved on the basis of clinical testing. But the reality is different. The minute a drug receives the green light from the F.D.A. for a specific treatment, the sponsoring company and its allies begin campaigns to make it available for other purposes or for other types of patients. The antidepressant Paxil was tested on adults but sold off-label to treat children. Seroquel, an anti-psychotic, was marketed as a treatment for depression. Physicians, often on retainer from pharmaceutical companies, are free to prescribe a drug for any reason if they entertain a belief that it will work. This practice turns the population at large into unwitting guinea pigs whose adverse reactions may go unreported or even unrecognized.
To secure the F.D.A.’s approval for Seroquel, which ultimately would go to treat schizophrenia, bipolar disorders, and manic episodes associated with bipolar disorder, AstraZeneca, the fifth-largest pharmaceutical company, conducted clinical trials across Asia, Europe, and the United States. Among the sites: Shenyang and more than a dozen other cities in China, and multiple cities in Bulgaria, Estonia, Hungary, Latvia, Lithuania, Croatia, Indonesia, Malaysia, Poland, the Russian Federation, Serbia, Ukraine, and Taiwan. The F.D.A. initially approved the drug for the treatment of schizophrenia. But while schizophrenia may have opened the door, off-label sales opened the cash register. Money poured in by the billions as AstraZeneca promoted the drug for the treatment of any number of other conditions. It was prescribed for children with autism-spectrum disorders and retardation as well as for elderly Alzheimer’s patients in nursing homes. The company touted the drug for treatment of aggression, anxiety, anger-management issues, attention-deficit hyperactivity disorder, dementia, and sleeplessness. Up to 70 percent of the prescriptions for Seroquel were written for a purpose other than the one for which it had been approved, and sales rose to more than $4 billion a year.
It turned out, however, that AstraZeneca had been less than candid about the drug’s side effects. One of the most troubling: patients often gained weight and developed diabetes. This meant a new round of drugs to treat conditions caused by Seroquel. In an internal e-mail from 1997 discussing a study comparing Seroquel with an older anti-psychotic drug, Haldol, a company executive praised the work of the project physician, saying she had done a great “smoke-and-mirrors job,” which “should minimize (and dare I venture to suggest) could put a positive spin (in terms of safety) on this cursed study.” After the e-mail was disclosed, in February 2009, the company said that the document cannot “obscure the fact that AstraZeneca acted responsibly and appropriately as it developed and marketed” the drug. In April, AstraZeneca reached a half-billion-dollar settlement with the federal government over its marketing of Seroquel. The U.S. attorney in Philadelphia, where the settlement was filed, declared that the company had “turned patients into guinea pigs in an unsupervised drug test.” Meanwhile, the company was facing more than 25,000 product-liability lawsuits filed by people who contended the drug had caused their diabetes.
Death Toll
The only people who seem to care about the surge of clinical trials in foreign countries are the medical ethicists—not historically a powerhouse when it comes to battling the drug companies. A team of physician-researchers from Duke University, writing last year in the New England Journal of Medicine, observed that “this phenomenon raises important questions about the economics and ethics of clinical research and the translation of trial results to clinical practice: Who benefits from the globalization of clinical trials? What is the potential for exploitation of research subjects? Are trial results accurate and valid, and can they be extrapolated to other settings?” The Duke team noted that, in some places, “financial compensation for research participation may exceed participants’ annual wages, and participation in a clinical trial may provide the only access to care” for those taking part in the trial. In 2007, residents of a homeless shelter in Grudziadz, Poland, received as little as $2 to take part in a flu-vaccine experiment. The subjects thought they were getting a regular flu shot. They were not. At least 20 of them died. The same distorting economic pressures exist for local hospitals or doctors, who may collect hundreds of dollars for every patient they enroll. In theory, a federal institutional review board is supposed to assess every clinical trial, with special concern for the welfare of the human subjects, but this work, too, has now been outsourced to private companies and is often useless. In 2009 the Government Accountability Office conducted a sting operation, winning approval for a clinical trial involving human subjects; the institutional review board failed to discover (if it even tried) that it was dealing with “a bogus company with falsified credentials” and a fake medical device. This was in Los Angeles. If that is oversight in the U.S., imagine what it’s like in Kazakhstan or Uganda. Susan Reverby, the Wellesley historian who uncovered the U.S. government’s syphilis experiments in Guatemala during the 1940s, was asked in a recent interview to cite any ongoing experimental practices that gave her pause. “Frankly,” she said, “I am mostly worried about the drug trials that get done elsewhere now, which we have little control over.”
The pharmaceutical industry, needless to say, has a different view. It argues that people participating in a clinical trial may be getting the highest quality of medical care they have ever received. That may be true in the short term. But, unfortunately, the care lasts only until the trial is completed. Many U.S. medical investigators who manage drug trials abroad say they prefer to work overseas, where regulations are lax and “conflict of interest” is a synonym for “business as usual.” Inside the United States, doctors who oversee trials are required to fill out forms showing any income they have received from drug companies so as to guard against financial biases in trials. This explains in part why the number of clinical-trial investigators registered with the F.D.A. fell 5.2 percent in the U.S. between 2004 and 2007 while increasing 16 percent in Eastern Europe, 12 percent in Asia, and 10 percent in Latin America. In a recent survey, 70 percent of the eligible U.S. and Western European clinical investigators interviewed said they were discouraged by the current regulatory environment, partly because they are compelled to disclose financial ties to the pharmaceutical industry. In trials conducted outside the United States, few people care.
In 2009, according to the Institute for Safe Medication Practices, 19,551 people died in the United States as a direct result of the prescription drugs they took. That’s just the reported number. It’s decidedly low, because it is estimated that only about 10 percent of such deaths are reported. Conservatively, then, the annual American death toll from prescription drugs considered “safe” can be put at around 200,000. That is three times the number of people who die every year from diabetes, four times the number who die from kidney disease. Overall, deaths from F.D.A.-approved prescription drugs dwarf the number of people who die from street drugs such as cocaine and heroin. They dwarf the number who die every year in automobile accidents. So far, these deaths have triggered no medical crusades, no tough new regulations. After a dozen or so deaths linked to runaway Toyotas, Japanese executives were summoned to appear before lawmakers in Washington and were subjected to an onslaught of humiliating publicity. When the pharmaceutical industry meets with lawmakers, it is mainly to provide campaign contributions.
And with more and more of its activities moving overseas, the industry’s behavior will become more impenetrable, and more dangerous, than ever.
