Phase 2a Trial for LSTA1 Begins with First GBM Patient

Lisata Therapeutics, a pharmaceutical firm in the clinical stage, is venturing into a new phase of research with the initiation of a Phase 2a trial for LSTA1, a drug designed to enhance the treatment of glioblastoma multiforme (GBM), a highly aggressive form of brain cancer. The first patient has been enrolled in Estonia, marking a significant step in the clinical development of LSTA1.

The trial is a randomized, double-blind, and placebo-controlled study that will assess the efficacy of LSTA1 when combined with the standard temozolomide treatment for newly diagnosed GBM patients. It is set to take place across multiple locations in Estonia and Latvia, aiming to include 30 participants. The study design favors the LSTA1 treatment group with a 2:1 randomization ratio. Lisata is not only providing the drug for the trial but also the financial backing.

LSTA1 operates on a unique mechanism, activating a novel pathway that allows for more effective penetration of co-administered anti-cancer drugs into solid tumors. This approach is expected to improve the drug's ability to reach and accumulate within the tumor, potentially modifying the tumor microenvironment to increase the effectiveness of immunotherapies. Previous non-clinical studies have shown promising results, enhancing the delivery of various anti-cancer therapies, including chemotherapeutics and RNA-based treatments.

Kristen K. Buck, Lisata's Executive Vice President of R&D and Chief Medical Officer, expressed optimism about the potential of LSTA1 in treating GBM, citing preclinical evidence that suggests the drug can overcome the blood-brain barrier's limited permeability. The company is eager to observe the outcomes of the trial closely.

Dr. Lenne-Triin Kõrgvee, the principal investigator leading the study, also shared her enthusiasm for exploring LSTA1's capabilities in addressing GBM, a disease that has historically been challenging to treat effectively.

Lisata Therapeutics is focused on developing innovative therapies for advanced solid tumors and other severe illnesses. Their flagship candidate, LSTA1, is built on the CendR Platform® Technology, which has already resulted in significant partnerships for research and development. The company anticipates announcing several clinical and business milestones in the coming years and is confident that its current capital will support its operations through these achievements and into the early part of 2026.

The company's commitment to advancing LSTA1 reflects a broader mission to improve treatment options for patients with serious diseases, particularly those facing the devastating impact of GBM. With the trial now underway, all eyes are on the potential that LSTA1 holds for changing the landscape of cancer treatment.
