Following Guidance from U.S. Food & Drug Administration in Type-C Meeting Lipella Pharmaceuticals to Advance Lead Product Candidate to Phase 2b

Company to initiate Phase 2b clinical trial in lead asset, LP-10 in 2H 2024

PITTSBURGH, May 21, 2024 (GLOBE NEWSWIRE) -- Lipella Pharmaceuticals Inc. (NASDAQ: LIPO) (“Lipella” or the “Company”), a clinical-stage biotechnology company, announced today the receipt of U.S. Food & Drug Administration (“FDA”) Type-C meeting guidance regarding the LP-10 (liposomal tacrolimus) clinical program. Lipella expects to initiate a Phase 2b clinical trial evaluating LP-10 as a treatment for hemorrhagic cystitis in approximately 36 patients in the second half of 2024.

The FDA provided preliminary agreement on Lipella’s overall trial design, including objectives, safety monitoring, control group monitoring, the dosing protocol, the primary efficacy endpoint, and sample size considerations.

Lipella’s Chief Medical Officer, Dr. Michael Chancellor, stated, “We can now proceed with the confidence that our Phase 2b study design can successfully meet its regulatory objectives. This clarity significantly advances our value proposition.”

LP-10 is an intravesical liposomal formulation of tacrolimus, intended for the treatment of moderate to severe hemorrhagic cystitis. Lipella has demonstrated preliminary safety and efficacy of LP-10 in a Phase 2a study, which treated 13 patients with up to two courses of LP-10 intravesical bladder instillations, and resulted in improved urinary symptoms, including decreased hematuria, decreased cystoscopic bleeding, and a reduced number of ulceration sites. Pharmacokinetic analysis demonstrated LP-10’s very short duration of systemic uptake.
