The Professor Who Had to Spend Half His Life to Make the Drug India Needs

Sujoy Guha has spent 37 years trying to realise Risug, a long-term use reversible male contraceptive – itself an unusual thing. It should have come to be more than a decade ago.


verything is still the same.
Sujoy Kumar Guha, professor emeritus at IIT-Kharagpur, wakes up around 11 am, reads the paper and thinks of what science can offer as solutions to the big problems of the day. In the evenings he runs his PhD students off their feet with constant demands, yet somehow leaves them itching to do something worthy of him. Around midnight, he takes off for a jog around the handsome campus with a leather belt wrapped around his right palm to fend off the stray dogs. He is still the slight, sprightly, soft-spoken man he was. He still answers questions after a few seconds' silence with a lateral anecdote. He still describes most persons as a "very nice man".
Everything is much the same as in 2002, when the then health minister C.P. Thakur had announced the imminent launchof Guha's drug molecule Risug, a reversible male contraceptive. But the clinical trials were then halted on the charge that Risug was toxic. It took five years for the professor to restart the trials. In 2016, Risug is once again almost ready for its launch at the tail end of the phase III clinical trials that have been "99% successful", according to the ICMR. Only, he was 62 then, he is 76 now. And in the past 14 years have been spent in proving what he had already proved successfully.
"We have completed testing on 282 volunteers in five centres across India, and zero side-effects and difficulties have been reported," said Dr R.S. Sharma, head of Reproductive Biology and Maternal Health at the Indian Council of Medical Research (ICMR), in a telephone interview. "I am waiting to reach 300 volunteers and then I will submit Risug for approval to the Drug Controller General of India. It is very unusual, in fact. I have worked on Risug for 25 years and not a single problem has been reported so far."

Registration of herbal trials in CTRI is not mandatory

A trial patient visited the site complaining breathlessness and tachycardia. The investigator advised hospitalization but as subject could not afford the expenses, he refused for admission. Is this an SAE because investigator advised hospitalization? G Praveen Kumar. If the patient was not hospitalized, it does not fall into SAE criteria of hospitalization. However, it appears from your mail that the PI felt that the event was serious enough to admit the subject for treatment. This makes it an “important medical event." As per ICH E2A such event also are considered serious. See the ICH E2A excerpt below: Medical and scientific judgement should be exercised in deciding whether expedited reporting is appropriate in other situations, such as important medical events that may not be immediately life-threatening or result in death or hospitalisation but may jeopardise the patient or may require intervention to prevent one of the other outcomes listed in the defin...

Evidence for Atypical Antipsychotic Drugs Called into Question

Despite massive advertising and booming prescriptions, use and sales, the new atypical antipsychotic medications such as Seroquel and Abilify – used to treat schizophrenia , bipolar disorder, depression and other illnesses – lack sufficient evidence to support their widespread and generalized usage. This according to a new study out of the Stanford University School of Medicine and University of Chicago. In the past decade, atypical antipsychotics have rocketed past many commonly prescribed, but older antidepressant and other psychiatric medications. Although initially touted as having few side effects, followup studies have found that atypical antipsychotics have serious side effects, including significant weight gain that can lead to diabetes and heart disease. “Because these drugs have safety issues, physicians should prescribe them only when they are sure patients will get substantial benefits,” said Randall Stafford, M.D., Ph.D., a Stanford associate pro...

In India, there is no separate guidance on pregnancy reporting

How will we conclude that the subject is illiterate? Dr Prakash Atlam The guidelines don’t use the term illiterate. Their focus is subject’s ability to read and/or write. Schedule Y treats anyone who is unable to read or write in the same way. See the excerpt below. If the subject or his/her legally acceptable representative is unable to read/write - an impartial witness should be present during the entire informed consent process who must append his/her signatures to the consent form. While designing a protocol we found that there are high likely chances of worsening of some of the symptoms. Do we have to wait for these to happen and report it as SAE or in case we define them in the protocol upfront then can we prevent from expediting reporting it as SAE? Om Please see suggested guidance from ICH. Exemption from reporting such events would require prior agreement with regulatory authorities. ICH E3 12.2.2 Display of Adverse Events: All adverse events occurrin...
