Rintatolimod is under clinical development by AIM ImmunoTech and currently in Phase II for Human Immunodeficiency Virus (HIV) Infections (AIDS). According to GlobalData, Phase II drugs for Human Immunodeficiency Virus (HIV) Infections (AIDS) have a 39% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Rintatolimod’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.
