Certepetide shown to promote immune cell infiltration into tumors and inhibit metastasis

BASKING RIDGE, N.J., July 10, 2024 (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 announces promising preclinical results for its investigational candidate, certepetide (formerly LSTA1). The data, presented in a poster by Dr. Dan G. Duda of Massachusetts General Hospital at the 2024 Cholangiocarcinoma Foundation Annual Conference, showed that certepetide combined with standard-of-care chemotherapy and immunotherapy improved survival in mice with intrahepatic cholangiocarcinoma. These findings suggest potential benefits for human patients with this aggressive cancer and support advancing clinical development efforts for certepetide in intrahepatic cholangiocarcinoma.

“Previous preclinical and early clinical results for certepetide show promise, and Lisata is optimistic about its potential to benefit patients with advanced solid tumors, including cholangiocarcinoma,” stated Kristen K. Buck, M.D., Executive Vice President of Research and Development and Chief Medical Officer at Lisata. “We are currently conducting a Phase 2a clinical trial, known as the BOLSTER trial, to evaluate certepetide in combination with standard-of-care chemotherapy as first-line treatment for cholangiocarcinoma. Additionally, based on the recommendations of the investigators involved in BOLSTER and the serious unmet medical need for treatments in a second line, we will soon be adding another arm to BOLSTER to test certepetide in combination with standard-of-care chemoimmunotherapy in intrahepatic cholangiocarcinoma patients. We look forward to sharing updates on this trial throughout the year, with results anticipated for both arms during 2025.”

Dr. Duda's research, titled "Enhancing the Efficacy of Standard Therapy in Intrahepatic Cholangiocarcinoma Using LSTA1 (certepetide), a Novel Tumor Targeting and Penetration Agent,” evaluated the efficacy of certepetide alongside standard anti-PD-1 immunotherapy and gemcitabine/cisplatin chemotherapy in an aggressive intrahepatic cholangiocarcinoma mouse model. The study demonstrated that certepetide, in combination with standard chemotherapy plus immunotherapy, significantly prolonged survival, reduced disease morbidity (ascites and pleural effusions), and lung metastasis, and decreased the risk of death by 76%. Treatment was well tolerated in mice, with no overt additional toxicities. Initial data suggest that certepetide promoted immune cell infiltration into the tumor tissues by opening the collapsed tumor vessels and enhancing immune cell infiltration.

“These preclinical data on certepetide are very encouraging,” stated Prof. Dan G. Duda. “Intrahepatic cholangiocarcinoma is a devastating disease with a poor prognosis, and there remains a critical need for new and improved treatment options. These findings, while based on an animal model, support the continued development of certepetide as a potential breakthrough treatment in patients living with intrahepatic cholangiocarcinoma.”

About Intrahepatic Cholangiocarcinoma

Intrahepatic cholangiocarcinoma, also known as intrahepatic bile duct cancer, is a rare, aggressive cancer that starts in the bile ducts within the liver. It is the second most common liver malignancy, making up about 10% of all cholangiocarcinoma. Intrahepatic cholangiocarcinoma has an overall poor prognosis, and symptoms are usually nonspecific, contributing to an advanced tumor stage at diagnosis.

About Certepetide

Certepetide (formerly LSTA1) is an investigational drug designed to activate a novel uptake pathway that allows co-administered or tethered anti-cancer drugs to 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 has also been shown to modify the tumor microenvironment, diminishing its immunosuppressive nature and inhibiting the metastatic cascade. We and our collaborators have amassed significant non-clinical data demonstrating enhanced delivery of various 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.).
