NASDAQ:LIPO A Clinical Stage Biotechnology Company Addressing Serious Diseases with Significant Unmet Need Business Growth Strategy Focused on rare and orphan drug indications and leveraging the 505(b)(2) pathway. Lipella anticipates this strategy will lower cost and allow for a faster approval process Why rare and orphan drugs? • Lipella can be first to market by pursuing conditions for which there are no current FDA approved treatments. • Requires smaller and less costly drug trials with greater flexibility from the FDA. • Orphandrugmarket exclusivity limits additional market entrants. • 7 years in the US, 10 years in the EU and Japan. 4 Why leverage the 505(b)(2) pathway? • Bypasses Phase 1 trials by utilizing drugs and mechanisms of action where safety and efficacy have already been established. • Canimmediately initiate Phase 2 clinical trials. • Potentially mitigates risk from a CMC, safety and clinical development standpoint. • Greater flexibility from the FDA.

A Clinical Stage Biotechnology Company Addressing Serious Diseases with Significant Unmet Need NASDAQ:LIPO Millions of patients are diagnosed each yearwith pelvic malignancies including prostate cancer, and cancers of the uterine corpus, requiring treatment. 20% of these patients receive pelvic radiation therapy during the treatment of their cancer, in addition to surgery and chemotherapy. Hemorrhagic cystitis is a potentially chronic, highly morbid condition with no approved drug therapy, and a four percent mortality rate. Years after receiving treatment, many patients acquire hemorrhagic cystitis, uncontrolled bladder blood loss. An increasing US population is surviving cancer therapies, including pelvic radiation, and chemotherapies that damage DNA. 10 Hemorrhagic Cystitis, Uncontrolled Urinary Blood Loss Hemorrhagic cystitis is a serious, life -threatening bladder damage from pelvic radiation therapy and/or bladder -toxic chemotherapy.

This end point is suggested as a direct measurement for hemorrhagic cystitis and potentially serves as a surrogate endpoint for the indication of refractory moderate to severe HC . Primary Efficacy Endpoint: Key criteria: Prospective, 40 -subject, multi -center clinical trial, randomized 1:1: expedited treatment group, delayed treatment group Subjects randomized into the delayed treatment group will alternatively receive four weeks standard of care HC treatment instead of LP -10 All study subjects will be evaluated for urinary bleeding as measured by cystoscopy at four weeks (after cystoscopic evaluation, subjects in the delayed treatment group will be treated with LP -10).
