GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.

Sirolimus overview

Sirolimus (Rapamun, Rapamune, Rapalimus) is a macrolide lactams derivative drug belongs to immunosuppressive agent and an anti-neoplastic agent. Sirolimus is a macrocyclic lactone produced by Streptomyces hygroscopicus.
