Clinical Trials - Phase IV

Phase IV trials are post-marketing studies to delineate additional information including the drug's risks, benefits, and optimal use. It also involves post-launch safety surveillance and ongoing technical support of a drug, helping detect long term adverse effects in a larger population. In situations where adverse effects are detected the durgs usage may be restricted or at times even withdrawn.

Phase IV studies can be conducted either by regulatory authorities or by the Pharmceutical company sponsoring the drug either for competitive or other reasons.

My colleagues and I have just concluded one of India's most in-depth studies on "Clinical Trials in India". We have looked at various areas such as:
- Market Trends
- Growth Drivers
- Regulatory Bodies and Framework
- Major Players.
-Etc.
We interviewed over 200 individuals and firms to collect the data in what we believe is one of the most detailed study on the subject in India.
