X4 Pharma Gains ‘Breakthrough’ for Mavorixafor

FDA has granted X4 Pharmaceuticals a breakthrough therapy designation for mavorixafor for the treatment of adult patients with WHIM (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis) syndrome, a rare, inherited, primary immunodeficiency disease caused by genetic mutations in the CXCR4 receptor gene. The company described mavorixafor as a potential first-in-class, once-daily, oral, small molecule antagonist of chemokine receptor CXCR4, and is currently being investigated in a pivotal Phase 3 global clinical trial, 4WHIM, for the treating the syndrome.
