VANCOUVER, British Columbia, June 28, 2021 (GLOBE NEWSWIRE) -- WPD Pharmaceuticals Inc. WBIO8SV (the "Company" or "WPD") a clinical-stage pharmaceutical company, today provided an update on its Berubicin drug candidate clinical development program for the treatment of glioblastoma multiforme (GBM).
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.
Phase II Adult Glioblastoma Clinical Trial
Berubicin's Phase I clinical trial in adults, the first time it was tested in humans, yielded promising results with 44% of the patients with glioblastoma multiforme (GBM) showing a clinical response of stable disease or better based on limited clinical data. This response rate rises to 49% in Avastin-naive patients. Importantly, Berubicin has shown evidence of improved overall survival in a patient population that currently has a dismal median survival rate of only 14.6 months from diagnosis.
WPD expects final approval from the Office for Registration of Medicinal Products, Medical Devices and Biocidal Products shortly and anticipates starting a Phase II Trial in the second half of 2021. Based on the promising Phase I results, WPD plans to commence a multicenter, open-label, Phase Ib/II efficacy, and safety study of Berubicin utilizing a Simon's 2-stage design to confirm the efficacy (or futility) of a single arm of Berubicin treatment, administered at the recommended Phase II dose (RP2D) identified in the Phase I study (7.5 mg/m2 Berubicin HCl), on the endpoint of Overall Response Rate in up to approximately 61 patients with GBM. The trials will include an interim analysis of the first 18 patients in the first half of 2022 for efficacy and safety as well as an extensive pharmacokinetic profile for these patients.
More details about study could be found on ClinicalTrials.gov under number NCT04915404. After approval of the study by the Regulatory Agency clinical sites data will also be available.

Phase I Pediatric Clinical Trial for Malignant Gliomas
WPD is planning the Phase I clinical trial for malignant gliomas at two clinical sites in Poland. The study includes a multicenter, open-label, dose escalation Phase I study of intravenous Berubicin in pediatric patients. The purpose of this first-in-pediatrics study is to examine the safety, tolerability, and pharmacokinetics of Berubicin and to estimate its MTD and/or RP2D when administered to pediatric patients with progressive, refractory, or recurrent HGG who have completed at least 1 standard line of therapy. This study will also make a preliminary assessment of the antitumor activity of Berubicin in this patient population in up to approximately 35 patients. This Phase I trial of Berubicin represents the first ever investigation of Berubicin in pediatric brain tumors.
WPD has already received Ethical Committee approval for Phase I clinical trial and has submitted its request for approval from the Office for Registration of Medicinal Products, Medical Devices and Biocidal Products. Information on approval and study number in European clinical trials database will be provided within 60 days. WPD expects to commence the Phase I clinical trial in Q3/Q4 2021.
CNS Commences Patient Enrollment in Potentially Pivotal Study of Berubicin
CNS Pharmaceuticals CNSP ("CNS"), the company that sublicenses the compound Berubicin to WPD for 30 countries mainly in Europe and Asia, announced open enrollment in the United States for its clinical study evaluating the efficacy and safety of Berubicin in the treatment of recurrent GBM.
CNS's potentially pivotal trial is an adaptive, multicenter, open-label, randomized and controlled study in adult patients with recurrent glioblastoma multiforme (WHO Grade IV) after failure of standard first-line therapy. The primary endpoint of the study is Overall Survival. Overall Survival is a rigorous endpoint that the U.S. Food and Drug Administration (FDA) has recognized as a 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 the current standard of care, with a 2 to 1 randomization of patients to receive either Berubicin or Lomustine.
Mariusz Olejniczak, CEO of WPD commented, "I am very pleased and excited about the development we have made on Berubicin both in the United States and in Europe. Our combined WPD and CNS clinical studies are going to start to recruit patients shortly which is an exciting step in the development programs. To ensure patients are informed and updated on possible sites, we will use clinicaltrials.gov as the primary source of information. We are hopeful that this is the first step in changing the landscape of glioma treatment with products in our pipeline and trough collaboration with different companies, scientific institutions, and our license partners. I would like to take an opportunity to thank both the WPD and CNS teams and our vendors and partners including WWCT and IAG for the hard work during pandemic months."
About Berubicin
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.
