VarmX Partners With CSL in a Strategic Collaboration and Option Agreement to Develop Novel Investigational Coagulation Treatment
17 September 2025
VarmX, a biotech company developing innovative approaches for the bypass of direct oral anticoagulants targeting activated factor Xa (FXa DOACs) and inherited coagulation disorders, has entered into a strategic collaboration with global biotechnology leader, CSL (ASX:CSL), to support the development of its lead asset, VMX-C001. VMX-C001 is a novel treatment to help restore blood coagulation in patients requiring urgent surgery or experiencing severe bleeding while on FXa DOACs. CSL has also entered into an exclusive option agreement with VarmX shareholders to acquire all issued and outstanding shares of the company.
Under the terms of the strategic collaboration agreement, CSL will fully fund VarmX’s global Phase 3 EquilibriX-S trial evaluating VMX-C001 in patients taking FXa DOACs who require urgent surgery. CSL will also fully fund and support VarmX in late-stage product development, manufacturing and pre-launch commercial and medical affairs activities.
CSL will make an upfront payment to VarmX shareholders of USD 117 million upon closing of the transaction for an exclusive option to acquire the company. CSL will have the right to exercise the option upon Phase 3 data. Subject to the achievement of certain milestones, following the exercise of the option and customary regulatory clearances, VarmX shareholders will receive a further USD 388 million in acquisition and additional payments up to the commercial launch of VMX-C001 and up to USD 1.7 billion in sales-based success milestones thereafter.
