CNS Pharmaceuticals Announces First Patient Enrolled in Spain in Ongoing Potentially Pivotal Global Trial Evaluating Berubicin for the Treatment of GBM

Enrollment continuing to progress toward an interim analysis, planned when 30-50% of subjects reach the primary endpoint expected mid-year 2023

HOUSTON, Feb. 7, 2023 /PRNewswire/ -- 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 the first patient in Spain has been enrolled in the Company's ongoing potentially pivotal global trial evaluating Berubicin for the treatment of recurrent glioblastoma multiforme (GBM), an aggressive and incurable form of brain cancer.

The Company has opened 37 clinical trial sites of the 59 sites selected across the U.S., Italy, France, Spain, and Switzerland. A pre-planned, non-binding futility analysis will be performed after approximately 30 to 50% of all planned patients have reached the primary endpoint. This review will include additional evaluation of safety as well as secondary efficacy endpoints. Enrollment will not be paused during this interim analysis.

"We continue to rapidly build momentum with patient enrollment across our clinical trial sites in Europe. The pace at which we are enrolling patients is encouraging and driving us toward our planned interim analysis, which we expect mid-year 2023. We sincerely appreciate the institutions, clinicians and staff that are contributing to the conduct of this trial, and are extremely grateful to the patients that choose to participate. We are laser focused on executing on clinical development plans and look forward to providing updates," commented John Climaco, CEO of CNS Pharmaceuticals.

Berubicin, is a novel anthracycline and the first anthracycline to appear to cross the blood-brain barrier. Berubicin is currently being evaluated in a potentially pivotal global study evaluating its efficacy and safety in the treatment of GBM. This trial is an adaptive, multicenter, open-label, randomized controlled study in adult patients with recurrent glioblastoma multiforme (WHO Grade IV) after failure of standard first-line therapy compared to 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. Results from the trial will compare Berubicin to current SOC (Lomustine), with a 2 to 1 randomization of patients to receive either Berubicin or Lomustine. The recently amended protocol expands eligibility for the study to patients who have received additional treatments as part of the first line therapy for their disease considering advancements in this area. This change was made due to the complexity of new agents introduced as a component of first line therapy, which allows an additional group of patients that can enroll on the study after what may constitute multiple procedures as their initial treatment.

The FDA has granted CNS Pharmaceuticals Fast Track Designation for Berubicin which enables more frequent interactions with them to provide 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.

CNS Pharmaceuticals a clinical-stage pharmaceutical company developing a pipeline of anti-cancer drug candidates for the treatment of primary and metastatic cancers of the brain and central nervous system. The Company's lead drug candidate, Berubicin, is a novel anthracycline and the first anthracycline to appear to cross the blood-brain barrier. Berubicin is currently in development for the treatment of a number of serious brain and CNS oncology indications including glioblastoma multiforme (GBM), an aggressive and incurable form of brain cancer.
