| August 8, 2023 | Lisata Therapeutics Announces U.S. FDA Orphan Drug Designation Granted to LSTA1 for the Treatment of Malignant Glioma | LSTA1 | Malignant Glioma | 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. LSTA1 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. LSTA1 also has the potential to modify the tumor microenvironment, making tumors more susceptible to immunotherapies. Lisata and its collaborators have amassed significant non-clinical data demonstrating enhanced delivery of a range of existing and emerging anti-cancer therapies, including chemotherapeutics, immunotherapies and RNA-based therapeutics. Additionally, LSTA1 has demonstrated favorable safety, tolerability and activity in clinical trials to enhance delivery of standard-of-care chemotherapy for pancreatic cancer. Lisata is exploring the potential of LSTA1 to enable a variety of treatment modalities to treat a range of solid tumors more effectively.Currently, LSTA1 is the subject of multiple ongoing or planned Phase 1b/2a and 2b clinical studies being conducted globally in a variety of solid tumor types in combination with a variety of anti-cancer regimens. In the coming months, the Company, in collaboration with investigators from the University of Tartu in Estonia, plans to initiate a clinical study evaluating LSTA1 in previously untreated glioblastoma multiforme (“GBM”) | FDA Orphan Drug Designation to LSTA1 for the Treatment of Malignant Glioma |
