Lisata Therapeutics Highlights Positive Preclinical Data of Certepetide as Part of Antibody-Drug Conjugate Combinations as Reported by Licensing Partner Catalent

BASKING RIDGE, N.J., Nov. 04, 2025 (GLOBE NEWSWIRE) -- Lisata Therapeutics, Inc. (Nasdaq: LSTA) (“Lisata” or the “Company”), a clinical-stage pharmaceutical company developing innovative therapies for the treatment of advanced solid tumors and other serious diseases, today highlighted positive preclinical data as announced by Lisata’s licensing partner, Catalent, Inc. (“Catalent”), at the 16thAnnual World ADC San Diego Conference, held November 3-6, 2025. Catalent’s presentation included data demonstrating the positive impact of incorporating Lisata's proprietary iRGD cyclic peptide product candidate, certepetide, and its analogs as a payload in Catalent’s SMARTag®antibody-drug conjugate (“ADC”) technology platform. Specifically, Catalent reported preclinical results showing that using certepetide as a non-cytotoxic ADC payload not only improved ADC efficacy but also broadened the distribution of the cytotoxic payload within the tumor microenvironment. A summary of these results can be foundherein the Company’s latest corporate presentation.

“This data is encouraging as it reinforces the large and growing body of evidence indicating that certepetide can enhance the targeting, penetration, and effectiveness of therapeutic agents - in this case, ADCs - in which it is chemically incorporated or co-administered,” stated Kristen K. Buck, M.D., Executive Vice President of Research and Development and Chief Medical Officer of Lisata. “ADCs are one of the fastest growing and most exciting therapeutic categories in drug development. These results underscore our belief in the value of our licensing partnership with Catalent and supports our strategy of leveraging certepetide’s unique mechanism to enhance the therapeutic potential across all modalities of treatments.”

Lisata licensed certepetide and its analogs to Catalent for use with its SMARTag®technology platform, as part of its Enhanced Conjugates innovations. Enhanced Conjugates are designed to amplify the effect of a cytotoxic payload by combining it with a non-cytotoxic payload, such as certepetide, with the goal of amplifying efficacy without compromising safety.

Certepetide (formerly LSTA1), aninternalizingRGD (arginyl-glycyl-aspartic acid or iRGD), cyclic peptide product candidate, is an investigational drug designed to activate a novel uptake pathway that allows co-administered or tethered anti-cancer drugs to target and penetrate solid tumors more effectively. Certepetide actuates this active transport system in a tumor-specific manner, resulting in systemically co-administered anti-cancer drugs more efficiently penetrating and accumulating in the tumor. Certepetide also has been shown to modify the tumor microenvironment resulting in tumors which are more susceptible to immunotherapies. We and our collaborators have amassed significant non-clinical data demonstrating enhanced delivery of a range of emerging anti-cancer therapies, including immunotherapies and RNA-based therapeutics. To date, certepetide has also demonstrated favorable safety, tolerability, and clinical activity in completed and ongoing clinical trials designed to test its ability to enhance the effectiveness of standard-of-care chemotherapy for pancreatic cancer. Lisata is exploring the potential of certepetide to enable a variety of treatment modalities to treat a range of solid tumors more effectively. Certepetide has been awarded Fast Track designation (U.S.) and Orphan Drug Designation for pancreatic cancer (U.S. and E.U.) as well as Orphan Drug Designation for glioma (U.S.) and osteosarcoma (U.S.). Additionally, certepetide has received Rare Pediatric Disease Designation for osteosarcoma (U.S.).

Lisata Therapeutics is aclinical-stage pharmaceutical companydedicated to the discovery, development and commercialization of innovative therapies for the treatment of advanced solid tumors and other major diseases. Lisata’s cyclic peptide product candidate,certepetide, is an investigational drug designed to activate a novel uptake pathway that allows co-administered or tethered anti-cancer drugs to selectively target and penetrate solid tumors more effectively. Lisata has already established noteworthy commercial and R&D partnerships based on itsCendR Platform®technology. The Company expects to announce numerous milestones over the next 1.5 years and believes that its projected capital will fund operations into the first quarter of 2027, encompassing anticipated data milestones from its ongoing clinical trials.
