X4 Pharmaceuticals Secures $27M in Series B Financing

X4 Pharmaceuticals, a Cambridge, MA-based clinical stage biotechnology company developing novel CXCR4 inhibitor drugs to improve immune cell trafficking to treat cancer and rare diseases, completed a $27m Series B financing.

Cormorant Asset Management participated in the funding.

The company intends to use the proceeds to advance its two lead drug candidates in clinical efficacy studies in immuno-oncology and a pivotal study in WHIM syndrome, a rare primary immunodeficiency disease.

Led by Paula Ragan, PhD, President and CEO, X4 Pharmaceuticals is developing novel therapeutics designed to improve immune cell trafficking to treat cancer and rare diseases. The company’s oral small molecule drug candidates inhibit the CXCR4 receptor, a pathway which plays a central role in immune surveillance. Its most advanced product candidate, X4P-001-RD, is in a Phase 2/3 study in patients with WHIM syndrome, a rare genetic, primary immunodeficiency disease. X4P-001-IO is currently under investigation in multiple Phase 1/2 studies in refractory clear cell renal cell carcinoma (ccRCC) and melanoma.
