CNS Announces the FDA has Granted Orphan Drug Designation for Brain Cancer Drug Berubicin
HOUSTON, June 11, 2020 /PRNewswire/ -- CNS PHARMACEUTICALS AG, (Nasdaq: CNSP) ("CNS" or the "Company"), a biopharmaceutical company specializing in the development of novel treatments for primary and metastatic cancers of the brain and central nervous system, today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) for its lead product Berubicin for the treatment of malignant gliomas.
"We are pleased to receive Orphan Drug Designation for Berubicin, our lead candidate. The designation provides Berubicin with a special status that can accelerate its development to treat malignant gliomas, and provides CNS with the potential for market exclusivity upon the drug's approval," stated John Climaco, CEO of CNS Pharmaceuticals. "In the Phase 1 trial of Berubicin to treat glioblastoma, one of the world's most aggressive cancers, under a prior developer, 44% of the patients demonstrated a significant improvement in progression free survival, and one patient experienced a complete response. We look forward to continuing to execute on our strategic plan and initiating a Phase II trial evaluating the effect of Berubicin on patients with glioblastoma later this year."
Chief Medical Officer of CNS, Dr. Sandra Silberman, stated, "We are excited to continue to drive the development of Berubicin and work towards addressing a critical unmet medical need. Glioblastoma currently has a dismal survival rate of only 14.6 months from its diagnosis. We believe Berubicin, which based on limited clinical data appears to be the first anthracycline to cross over the blood brain barrier in adults, provides a potentially novel therapy for the treatment of malignant gliomas."
The FDA grants Orphan Drug Designation status to products that treat rare diseases, providing incentives to sponsors developing drugs or biologics. The FDA defines rare diseases as those affecting fewer than 200,000 people in the United States at any given time. Due to small patient numbers, treatment for these rare diseases would not be considered economically feasible without government programs to support their economic viability. Orphan drug status is intended to facilitate drug development for rare diseases and may provide several benefits to drug developers, including tax credits for qualified clinical trials costs, exemptions from certain FDA application fees, and seven years of market exclusivity upon regulatory product approval.
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.
About CNS Pharmaceuticals, Inc.
CNS Pharmaceuticals is developing novel treatments for primary and metastatic cancers of the brain and central nervous system. Its lead drug candidate, Berubicin, is proposed for the treatment of GBM, an aggressive and incurable form of brain cancer. CNS holds a worldwide exclusive license to the Berubicin chemical compound and has acquired all data and know-how from Reata Pharmaceuticals related to a completed Phase 1 trial with Berubicin in GBM which Reata conducted in 2006. In this trial, 44% of patients experienced a statistically significant improvement in progression-free survival. This 44% disease control rate was based on 11 patients (out of 25 evaluable patients) with stable disease, plus responders. One patient experienced a durable complete response and remains cancer-free as of February 20, 2020. In the second half of 2020, CNS expects to commence a Phase 2 clinical trial of Berubicin for the treatment of GBM in the U.S., while a sub-licensee partner undertakes a Phase 2 trial in adults and a first-ever Phase 1 trial in pediatric GBM patients in Poland. Its second drug candidate, WP1244, is a novel DNA binding agent that has been shown in preclinical studies to be 500-times more potent than the chemotherapeutic agent daunorubicin in inhibiting tumor cell proliferation.
