Influenza (quadrivalent) vaccine is under clinical development by Vaxxas and currently in Phase I for Influenzavirus B Infections. According to GlobalData, Phase I drugs for Influenzavirus B Infections have an 88% phase transition success rate (PTSR) indication benchmark for progressing into Phase II. GlobalData’s report assesses how Influenza (quadrivalent) vaccine’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.

Influenza (quadrivalent) vaccine overview

The vaccine candidate is under development for the prevention of influenzavirus A infections, influenzavirus B infections and seasonal influenza. It is a quadrivalent inactivated influenza virus vaccine administered through intradermal route in the form of patch. The therapeutic candidate is being developed based on high density micro array patch (HD-MAP) technology.

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

GlobalData’s Likelihood of Approval analytics tool dynamically assesses and predicts how likely a drug will move to the next stage in clinical development (PTSR), as well as how likely the drug will be approved (LoA). This is based on a combination of machine learning and a proprietary algorithm to process data points from various databases found on GlobalData’s Pharmaceutical Intelligence Center.
