The European Commission has approved XOLREMDI (mavorixafor) from X4 Pharmaceuticals for once‑daily oral treatment of patients aged 12 and older with WHIM syndrome. The approval was granted under exceptional circumstances and is based on the Phase 3 4WHIM study; mavorixafor is thus the first and only approved therapy for WHIM in the US and the EU. Norgine will lead commercialization in Europe, Australia and New Zealand following regulatory approvals; under the licensing agreement X4 can receive up to €226 million in milestone payments plus tiered royalties. » Altro su de.investing.com
