Memo Therapeutics: FDA Fast Track designation for infection treatment

Memo Therapeutics AG (“MTx”), a biotech company developing best-in-class therapeutic antibodies, announced today that the U.S. Food and Drug Administration (“FDA”) has granted Fast Track designation to AntiBKV, MTx’s lead antibody therapeutic that targets BK polyomavirus (“BKV”) infection commonly seen in renal transplant patients. AntiBKV has successfully completed a phase I clinical study and following FDA clearance has started actively recruiting patients for a pivotal phase II/III clinical trial.

The FDA’s Fast Track process has been designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need. This means important new drugs could potentially get to the patient earlier. There are currently no therapeutics to treat BKV infection.

“Receiving Fast Track designation from the FDA is a significant achievement for Memo, validating the potential of AntiBKV and expediting its development. We believe AntiBKV could be a first- and best-in-class treatment option for kidney transplant patients suffering from BKV infection,” said Dr. Karsten Fischer, Chief Executive Officer of Memo Therapeutics AG. “AntiBKV demonstrated very promising results in our phase I trial. We have recently started recruitment into a pivotal phase II/III clinical trial in the U.S. and plan for a subsequent BLA submission in 2024. We hope then to be able to offer patients a much needed therapeutic option by 2025 at the latest.”

BKV infection occurs mostly in childhood and remains dormant in healthy individuals. However, BKV infection poses a significant threat following kidney transplantation, with serious adverse effects on graft function and ultimately patient survival. Due to the immunosuppressive drug regimen transplant patients receive, reactivation of BKV is triggered in 40 to 50% of kidney transplant recipients. Up to 10% then progress to BKV associated nephropathy, which is the leading cause of graft loss. There is currently no disease modifying therapy available to treat BKV infection; it can only be treated by lowering immunosuppression. However, this significantly increases the risk of a graft rejection reaction, leading to impaired functionality and longevity, or graft failure.
