CSL (ASX:CSL) has partnered with VarmX to develop VMX-C001, a recombinant factor X protein to restore blood clotting in patients on Factor Xa inhibitors facing severe bleeding or requiring urgent surgery, according to a Tuesday Australian bourse filing.
The FXa inhibitor is used by more than 20 million patients globally for chronic anticoagulation therapy, with around 3% experiencing severe bleeding or requiring urgent surgery, the filing said.
The company will finance VarmX's global phase 3 trial and provide support for late-stage development, manufacturing, and pre-launch activities, per the filing.
The company will make an upfront payment of $117 million to VarmX for an exclusive option to acquire the company following phase 3 results, with potential additional payments of up to $388 million plus commercial milestones.
The treatment is slated for a commercial launch in 2029, the filing added.
