Thymalfasin is under clinical development by SciClone Pharmaceuticals and currently in Phase II for Cystic Fibrosis. According to GlobalData, Phase II drugs for Cystic Fibrosis have a 31% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Thymalfasin’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

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.

Thymalfasin overview

Thymalfasin (Zadaxin) is a synthetic polypeptide consisting of 28 amino acids, a synthetic version of thymosin alpha 1, a substance found naturally in the circulation and produced in the body's thymus gland.
