Mavorixafor is under clinical development by X4 Pharmaceuticals and currently in Phase II for Neutropenia. According to GlobalData, Phase II drugs for Neutropenia have a 95% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Mavorixafor’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.

Mavorixafor overview

Mavorixafor (X4P-001) is under development for the treatment of severe congenital neutropenia, Waldenstrom’s Macroglobulinemia, WHIM syndrome, melanoma and refractory solid tumors including clear cell renal cell carcinoma (ccRCC) and triple-negative breast cancer. It is administered through oral route. The drug candidate was under development for the treatment of human immunodeficiency virus (HIV) Infections (AIDS). The drug candidate acts by targeting C-X-C receptor type 4 (CXCR4).

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.
