Outsourcing Clinical Trials
Gaining Popularity
The skyrocketing cost of drug development over the past decade, coupled with
stiff competition for limited numbers of potential trial participants, has
compelled pharmaceutical and biotechnology companies to seek more cost effective
ways of conducting clinical research. This quest has led to outsourcing clinical
trials to developing countries where large numbers of qualified patient
volunteers await, the cost of doing business is far cheaper, and new
therapeutics can be brought to market faster.
The cold, hard facts are that:
- Clinical trials conducted in the U.S. typically cost about $150 million, 60%
more than in India, according to a study by Rabo Bank.[1]
- Recruitment time can be halved, a significant advantage to
sponsors seeking hundreds, and in some cases thousands, of clinical
trial participants.[1]
- India's billion-plus population offers tremendous genetic
diversity, and a large patient population that has never received
drug treatment, simplifying patient enrollment and trial management.[1]
- Whereas Western patients are often wary of participating in clinical trials,
many in India are eager to enroll in order to gain access to free medical care
and tests, as well as drugs they could not otherwise afford.[1]
- China, too, is becoming an increasingly popular site for
clinical trials, with sponsors drawn by its “potentially lucrative
market for new drugs, which some estimate will be worth $50 billion
in five years.”
[3]
- “In the first half of 2003, applications for clinical trials
soared 420 percent over the year before to almost 2,500,” according
to China's Department of Drug Registration. Demand is so great that
dozens of hospitals are being added to the 165 already permitted to
conduct human clinical trials.[3]
Dangers inherent in outsourcing clinical trials to developing countries:
- Review boards that oversee trials in developing countries often don't include
ethicists and “favor the interests of doctors and hospitals,” says Li Benfu,
president of the Chinese Medical Ethics Association.[3]
- Rapid growth in new trials may be overwhelming regulators in China.[3]
- Poor practices, an underfunded medical system, poor enforcement of regulations
and widespread poverty “threaten to erode trust between China's sick and dying
and its medical establishment, and undermine confidence in the medical data that
drug companies collect in China.”[3]
- Because foreign trial participants have cultural, nutritional, and economic
differences from the average American participant, precautions must be taken to
avoid skewing clinical trial results. One such example is the requirement that
one-third of the participants in any given clinical trial must come from the
U.S. and/or Europe.
Ethical concerns abound
As clinical trials expand overseas, ethics are a growing concern, with debate
focused on the possible exploitation and coercion of trial volunteers. As a
result, “drugs might be approved for use in the United States on the basis of
studies that don't meet U.S. standards,” says Peter Lurie, Deputy Director of
the Public Citizen’s Health Research Group, a consumer advocacy group based in
Washington DC.[7]
The FDA is considering the adoption of less restrictive rules for clinical
research conducted outside the U.S. These changes would:
- Allow the use of placebos in clinical trials to “assess the effectiveness of a
drug, even when there is a known effective treatment for the condition.”
- Eliminate the requirement that clinical trial participants be given the best
available treatment for their condition after the trial has ended. This is
popular with drug companies who “don’t want to be saddled with responsibility to
patients after studies are done,” said Lurie.
- Exempt overseas trials from adherence to the Declaration of Helsinki, a code
of medical ethics created by 82 national medical associations, to protect trial
participants.
- Require overseas trials need only comply with “good clinical practices,” which
is much weaker regarding patient protections.
“The Declaration of Helsinki is the standard-bearer for international research
ethics and enjoys particular respect in the developing world,” Lurie said. “It
would be tragic if the US tendency to arrogantly flout international laws
claimed the declaration as another victim, even as the President touts the
universalism of human rights.”[4] Despite everything, for India, the potential benefits of clinical research are
far greater than its hazards, says Rajesh Jain, Managing Director of drug maker
Panacea Biotec Ltd. “It brings in the best in industry practices in clinical
research for the benefit of our population's health-care needs while exposing
the medical community to global processes and standards.”[1]
