As others have mentioned, if adverse side effects are observed after the product was used/administered by a patient during a clinical trial, it is most likely paused until effects go away and a solution is found as to what is causing the effects. For most drugs, there would be side effects such as rashes, allergies, etc. however more severe side…[Read more]

Viraj D replied to the topic career path in the forum Clinical Trials for Medical Devices 7 years, 11 months ago
With my current experience working in the industry, taking part in clinical trials can be a very daunting task with quite a lot of paperwork. Finding a statistical significance can vary from 500 patients to even a couple thousand, so continually performing the same tests and procedures can get very repetitive. I would be more interested in working…[Read more]
