Clinical Trials
Recent Clinical Trials on Epivir-hbv:
Sometimes companies keep conducting clinical trials even after the drug's approval to discover new formulations, methods of use, or new treatment indications, so they could file for additional patents or receive regulatory exclusivity extensions, such as pediatric exclusivity, potentially delaying generic competition. Based on these recent clinical trials, generic companies need to consider the potential for new intellectual property or regulatory hurdles. These strategic moves by the drug owner might delay generic substitution or lead to additional sales of the brand drug, even after patent expiry.
