PSB-202 is under clinical development by Qilu Puget Sound Biotherapeutics and currently in Phase I for Waldenstrom Macroglobulinemia (Lymphoplasmacytic Lymphoma). According to GlobalData, Phase I drugs for Waldenstrom Macroglobulinemia (Lymphoplasmacytic Lymphoma) have a 73% phase transition success rate (PTSR) indication benchmark for progressing into Phase II. GlobalData’s report assesses how PSB-202’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.

PSB-202 overview

PSB-202 is under development for the treatment of follicular lymphoma, chronic lymphocytic leukemia, waldenstrom macroglobulinemia (lymphoplasmacytic lymphoma), marginal zone B-cell lymphoma, mantle cell lymphoma, extranodal marginal zone B-cell lymphoma (mucosa-associated lymphoid tissue or MALT-lymphoma). The drug candidate consisting of two engineered monoclonal antibodies Fc-enhanced humanized type II anti-CD20 IgG1 (PSB102) and a humanized anti-CD37 IgG1 (PSB107). The drug candidate is a monoclonal antibody and developed based on MabPair platform. MabPair platform produces mixture of antibodies that are targeting multiple molecules and pathways. It acts by targeting CD20 and CD37.

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 its clinical pathway (PTSR), as well as how likely the drug will be approved (LoA). This is based on a proprietary algorithm built from the drugs’ sales forecast, regulatory milestones, cost forecasts, WACC rate and other proprietary data sources found on GlobalData’s Pharmaceutical Intelligence Center.
