Translating unique human immune responses

into superior medicines

At Memo Therapeutics AG we are developing best-in-class therapeutic antibodies based on natural immunity in elite responders to transform the lives of patients with viral infections and cancer.

Memo Therapeutics AG, an Ipsen company is a late-stage biotech company developing best-in-class therapeutic antibodies to transform the lives of patients with viral infections.

Our lead program, potravitug, currently in Phase II development, is the most potent antibody ever tested in clinical trials to treat BK polyomavirus (“BKPyV”) infection in kidney transplant recipients. BKPyV infection can lead to nephropathy, loss of kidney function, as well as organ failure, rejection and death.

Oncology

We are mining antibody repertoires of tumor infiltrating B-cells from elite cancer patients to discover superior antibodies and targets to develop new medicines.

DROPZYLLA

Our proprietary DROPZYLLA® technology is a powerful antibody repertoire copying engine which enables the identification and isolation of the most potent antibodies created by the body’s immune response to viral infections and cancer.

Phase 2 for potravitug targeting BKV

We have completed recruiting patients in the largest placebo-controlled clinical trial for the treatment of BKPyV infection in kidney transplant recipients ever conducted. SAFE KIDNEY II (NCT05769582) is a Phase II double-blind, randomized, placebo-controlled trial with 90 patients in the USA. The trial aims to determine the safety, tolerability and efficacy of potravitug. Results from the Phase II study were presented at the World Transplant Congress (“WTC”) in August 2025.
