Ipsen SAIpsen acquires a first-in-class monoclonal antibody for BK virus, adding a promising late-stage asset to its Rare Disease pipeline.

Ipsen has completed its acquisition of Memo Therapeutics AG, a late-stage biotech company focused on the first-in-class monoclonal antibody potravitug. Potravitug targets BK polyomavirus reactivation in kidney transplant recipients, a condition with no approved targeted therapies that affects approximately 30% of patients within the first year after transplant. The acquisition adds potravitug to Ipsen's Rare Disease pipeline, building on promising Phase II results from the SAFE KIDNEY II trial, the largest placebo-controlled study in this patient population. Over 100,000 kidney transplants are performed each year worldwide, with more than 28,000 in the U.S. and over 90,000 patients on the waiting list.
