Ethics in Indian Clinical Trials

Happened to read an interesting article that discussed on the ethical aspects of clinical trials that are being conducted in India.

Not a new topic for the media to criticize but this was one was worth a read.

Excerpts from the article:

....In Gujarat, unemployed diamond workers and migrants from Uttar Pradesh and Bihar get paid between INR 5000 and INR 20,000 to take part in bioequivalence trials – sums large enough for them to put money over personal safety. Indeed, trial participants may be both financially and socially vulnerable. It is reported that Surender, who died in the Hyderabad felodipine trial, was one of a number of Dalit students being recruited for clinical trials in that city. Likewise, some years ago, a 22-year-old Adivasi youth died in a bioequivalence trial of the antidepressant citalopram by the Sun Pharma Advanced Research Centre in Vadodara...

....Another concern about trials in government hospitals is that they are conducted on poor people who may have no access to the drugs tested on them after the trial is over. In August 2008, the media reported that 49 children died in 42 clinical trials that were conducted over two and a half years in the Department of Paediatrics at the All India Institute of Medical Sciences (AIIMS) in Delhi. An investigation ordered by the National Human Rights Commission concluded that the trials were conducted properly: the children in the trials were seriously ill, and all the deaths occurred because of the serious illnesses, not the treatments. However, the committee’s report left many questions unanswered. What, for instance, was the purpose of these trials? Would they help other poor children in India?...

Ethicist Amar Jesani points out that ethics committees have a lot of power, as the DCGI requires that all trials be passed by such an appointed group. In fact, the DCGI only requires approval by an ethics committee, since it does not monitor the actual conduct of the trial – it does not check that informed consent is taken, that the investigators do their job correctly, that subjects are not harmed, and so on. Thus, says Jesani, it is the ethics committee, not the DCGI, that is the real regulator of clinical trials.

....Now, the FDA’s decision to do away with the Declaration of Helsinki will create a dilemma for the DCGI. If CROs in India are to follow the FDA requirements – such as using a placebo even when it is not absolutely necessary, and when it might put subjects at risk – they will be violating Indian regulations, which require that the Declaration of Helsinki be followed. The latest revision of the Declaration is quite clear that the placebo may be used in very few circumstances. At the moment, however, the DCGI’s record – permitting a number of unethical trials – suggests that his office places greater value on the potential financial returns of clinical trial outsourcing than on protecting the people who take part in drug trials in India...
