While 668 deaths were reported in 2010 and 438 in 2011, out of these, deaths attributed only "to clinical trials" were 22 and 16 respectively.
In a written reply to a question in the Lok Sabha, Minister for Health and Family Welfare Ghulam Nabi Azad said a total of 1,954 persons died from 2009 till June 2012 due to "serious adverse events of death" in clinical trials.
He said the serious adverse events of death may occur during clinical trials due to various reasons, which could be attributed to deaths relating to diseases like cancer or administration of drug on critical or terminally ill patients or side-effects or unrelated causes.
Azad, however, said deaths "attributed to clinical trials" in 2010 and 2011 after they were studied were only 22 and 16 respectively.
"The scrutiny of cases pertaining to the year 2012 is in process," the Minister said.
