Completion of enrollment of study on track by end of 2023
Topline data results from interim analysis also on track to announce by end of 2023
HOUSTON, TX / ACCESSWIRE / September 7, 2023 / CNS Pharmaceuticals, Inc. (NASDAQ:CNSP) ("CNS" or the "Company"), a biopharmaceutical company specializing in the development of novel treatments for primary and metastatic cancers in the brain and central nervous system, today announced that 200 of the expected 243 patients have now been enrolled in the Company's ongoing potentially pivotal study evaluating Berubicin for the treatment of recurrent GBM, an aggressive and incurable form of brain cancer.
This potentially pivotal, global study of Berubicin is an adaptive, multicenter, open-label, randomized controlled study in adult patients with recurrent GBM (WHO Grade IV) after failure of standard first-line therapy and compared to Lomustine as the standard of care (SOC). The primary endpoint of the study is Overall Survival (OS), a rigorous endpoint that the FDA has recognized as the basis for approval of oncology drugs when a statistically significant improvement can be shown relative to a randomized control arm. The Company has opened 46 clinical trial sites of the approximately 60 sites selected across the U.S., Italy, France, Spain, and Switzerland.
"As we have noted previously, patient volunteers and their treating clinicians are the backbone of our Berubicin development program. We are deeply sensitive to the fact that these brave patients are facing the battle of their lives and we are forever in their debt for the trust and confidence they and their treating clinicians have in Berubicin and the Company. That 200 such individuals have joined our trial helps to create the robust sample set we have desired from the beginning as we seek to conclusively demonstrate Berubicin's potential. All of us at the Company acknowledge that we simply cannot bring this exciting drug candidate forward without these remarkable patients. Furthermore, we believe the rapid and consistent pace of enrollment is not just remarkable in itself but continues to represent the extraordinarily high level of interest and enthusiasm among our investigators and patients. Addressing this devastating disease continues to be the driving force for our team and we are pleased to achieve this landmark milestone. Importantly, this takes us one step closer to bringing the study across the finish line and potentially offering an effective treatment in GBM that is safe and well tolerated," commented John Climaco, CEO of CNS Pharmaceuticals.
As previously announced, CNS Pharmaceuticals has reached the criteria required by the study protocol to conduct a pre-planned, non-binding futility analysis, which an independent Data Safety Monitoring Board (DSMB) will review to determine whether to recommend continuing the study as planned or modifying the study based on Berubicin showing potential value as a second-line treatment for patients with glioblastoma. CNS Pharmaceuticals previously reported that the Company would conduct this analysis after at least 50% of the patients in the population to be analyzed for the interim analysis (30-50% of the total number of patients for this trial) had reached the primary efficacy endpoint, as provided for in the study protocol. The DSMB will review the number of deaths in each arm to ensure that the overall survival of patients receiving Berubicin shows at least a statistically significant comparability to those receiving Lomustine. Additional analyses will include comparisons of secondary endpoints, including progression-free survival (PFS), response rates, and safety assessments. The Company is confident it will announce the results from the interim analysis publicly before the year end. Enrollment will continue during the interim analysis.

The FDA has granted CNS Pharmaceuticals Fast Track Designation for Berubicin which enables more frequent interactions with the agency for guidance on expediting the development and review process. Additionally, the Company has received Orphan Drug Designation from the FDA, which may provide seven years of marketing exclusivity upon approval of an NDA.
Berubicin is an anthracycline, a class of anticancer agents that are among the most powerful chemotherapy drugs and effective against more types of cancer than any other class of chemotherapeutic agents. Anthracyclines are designed to utilize natural processes to induce deoxyribonucleic acid (DNA) damage in targeted cancer cells by interfering with the action of topoisomerase II, a critical enzyme enabling cell proliferation. Berubicin treatment of brain cancer patients appeared to demonstrate positive responses that include one durable complete response in a Phase 1 human clinical trial conducted by Reata Pharmaceuticals, Inc. Berubicin, was developed by Dr. Waldemar Priebe, Professor of Medicinal Chemistry at The University of Texas MD Anderson Cancer Center.
