Pharmaceutical companies are using free-trade deals like CAFTA to eliminate global competition -- and deny poor patients access to cheaper generic drugs.
Aug 12, 2005 | In November 2004, Guatemala's Congress repealed a law that gave brand-name prescription drugs protection from generic competition. The law had allowed brand-name companies to conceal data that generic companies would use to bring their own versions to market, and public health activists hailed the move as a step toward greater access to essential medicines. But four months later, legislators reversed themselves and put those protections back in place. The protests that followed led to many injuries and one death. Why did this small nation, where cheap generic drugs have been key to treating one of Latin America's largest HIV-positive populations, change course?
In a word: CAFTA. Guatemala changed its laws in order to become part of the Central American Free Trade Agreement, which encompasses five Central American countries and the Dominican Republic. CAFTA, which President Bush signed last week after coaxing it through Congress, requires its members to adopt strict rules on intellectual property rights, including those protecting prescription drugs. These drugs cost up to 22 times what Doctors Without Borders, which runs several AIDS clinics in Guatemala, pays for generic equivalents. Some economists say similarly high drug costs would cause the unique universal healthcare system of nearby Costa Rica to collapse.
Though protections for the environment and workers' rights are often the most contentious issues surrounding trade deals such as CAFTA and NAFTA, pharmaceutical giants, aided by the U.S. government, are increasingly using these pacts to assert their power over markets in developing countries. Activists and public-health groups working on the ground say these companies put profits above public health by keeping generic medicines off the shelves, which keeps prices high and drugs out of reach to all but the most wealthy. These deals apply to all prescription drugs, but generics have been particularly effective at driving down the prices of drugs used to treat AIDS -- in some cases by 98 percent -- even as AIDS rates have skyrocketed. CAFTA is signed and delivered, and the United States is now preparing trade pacts with Thailand, South America and other parts of the developing world.
Even the Bush administration cites the falling price of drugs as a key reason it's possible to treat AIDS patients in developing countries. Generic competition is the only proven way to drive down those prices and thus broaden access. For example, Doctors Without Borders paid $216 a year to treat a patient in Guatemala while the Guatemalan government, buying brand-name equivalents, paid $4,818.
Costa Rica's free, universal system depends on cheap drugs to keep costs down. Roman Macaya, executive director of the National Chamber of Generic Products of Costa Rica, says that if CAFTA-like protections had been in place, buying drugs would have put the system in financial jeopardy. Along with the Dominican Republic and Nicaragua, Costa Rica has yet to sign on to CAFTA and drug-pricing promises to be a big issue in the country's upcoming presidential election. "Costa Rica will most likely have to adopt a policy where older drugs are prescribed rather than the latest drugs even if HIV strains have evolved to be resistant to those older drugs," Macaya says. "Most of the drug prices for the new drugs are going to be out of reach under CAFTA."
That, he and others say, is because CAFTA contains several provisions designed to limit generic access. For example, drug companies get 20-year patent protection for their drugs from the moment they begin research and development, but they can apply to extend that time period. (A drug usually takes about 15 years to come to market.) In the United States, that time is limited, but under CAFTA, there's no upper limit on the extension the companies could obtain.
A more dire consequence lies in the short term. Generic companies seeking approval of their drugs usually use safety data from clinical tests that the name-brand companies conducted, obviating the need to repeat expensive and time-consuming work. CAFTA allows the original manufacturers to keep that data secret for five years after a company registers a drug. Generic companies need that data to market their drugs because it's not financially feasible to repeat those studies. And according to Rachel Cohen of Doctors Without Borders' Campaign for Access to Essential Medicines, "The requirement to retest a drug already proven to be safe and effective is medically unethical, because it forces a number of patients to take part in clinical trials which are not necessary and requires some to take placebos in order to compare outcomes with the actual drug and therefore forgo a proven treatment."
The five-year clock starts ticking in a given country only when a drug is registered there, meaning that a company can prolong its monopoly by registering in countries sequentially. The result is up to 10 years of market protection from generics for a brand-name drug. (Drug companies are pushing for more time in other markets.) Guatemala had removed these data-protection requirements and then, at the behest of the United States and in order to comply with CAFTA, it reinstated them in March.
Technically, a developing country can grant a compulsory license, which allows a generic company to break a patent in exchange for royalties paid back to the patent holder. Several small countries have invoked these compulsory licenses, and Brazil has used the threat of doing so to get brand-name drug makers to lower their prices. But without access to the name-brand companies' data, generic companies can't get their drugs approved for market regardless of whether the drug is under patent. If a generic company can't market its drugs, it makes compulsory licensing meaningless and creates a climate in which Brazil's threats, for example, would be empty.
The United States supported compulsory licensing at World Trade Organization talks in 2001, and then endorsed the concept again in 2002. But in trade negotiations, it's another story. "The Bush Administration's trade negotiators have repeatedly pressured the developing countries to forgo their rights ... and to adopt intellectual property standards that impede access to essential medications," according to a report from the office of Rep. Henry A. Waxman, D-Calif. "In effect, the President's trade representatives have elevated the protection of pharmaceutical patents above the pressing health needs of developing countries."
