On July 20, 2015 DelMar Pharmaceuticals, Inc. (OTCQX: DMPI) ("DelMar" and the "Company"), a biopharmaceutical company focused on developing and commercializing proven cancer therapies in new orphan drug indications, reported that the Sarah Cannon Cancer Research Center at HealthOne, Denver, CO has been added as a clinical trial site for the ongoing, multicenter Phase I/II study of VAL-083 in patients with refractory glioblastoma multiforme (GBM), the most common and deadly form of human brain cancer (Press release, DelMar Pharmaceuticals, JUL 20, 2015, View Source [SID:1234506538]).

"This fifth clinical site greatly adds to our recruitment bandwidth as part of our strategy to increase patient access as we continue with the expansion phase of our Phase I/II GBM clinical trial. Our goal is to complete the expansion phase and advance VAL-083 into registration-directed Phase II/III clinical trials for refractory glioblastoma in the timeliest manner possible," said Jeffrey Bacha, president & CEO of DelMar Pharmaceuticals.
Sarah Cannon Research Institute (SCRI) is the research arm of HCA’s global cancer enterprise, Sarah Cannon. SCRI’s Denver site is directed by Gerald Falchook, M.D., M.S. Dr. Falchook completed his oncology training at MD Anderson Cancer Center, where he also served as a faculty member for six years developing investigator-initiated clinical trials as well as collaborating with pharma/biotech industry partners to bring promising new drugs to cancer patients.
"Expanding our collaboration with SCRI provides access to leading oncologists to support the development of VAL-083 as a novel cancer chemotherapy and will enable more rapid patient enrollment to our GBM clinical trial by accessing SCRI’s large network of patients," added Mr. Bacha.
DelMar’s multicenter Phase I/II study with VAL-083 is ongoing in patients with recurrent GBM. The clinical trial is an open-label, single arm, safety and tolerability dose-escalation study utilizing a standard dose escalation design, until the maximum tolerated dose (MTD) or the maximum specified dose has been reached. Eligible GBM inclusion criteria requires previous treatment with surgery and/or radiation, if appropriate. Eligible GBM patients must have failed both Avastin (bevacizumab) and Temodar (temozolomide) unless either of these therapies was contraindicated. (ClinicalTrials.gov Identifier NCT01478178).
Recently DelMar presented interim data from this ongoing study in GBM at the American Association of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual meeting. The Company confirmed the completion of the Phase I dose-escalation portion of the trial and presented data supporting a dose response trend: Patients receiving a dose ≥30mg/m2 had a median survival of 9.0 months vs. 4.4 months at doses <10mg/m2. DelMar also confirmed the initiation of a 14-patient Phase II expansion cohort at a dose of 40mg/m2. The purpose of the Phase II expansion cohort is to gain additional information about the safety and efficacy of VAL-083 at the 40mg/m2 dose prior to advancement into registration-directed Phase II/III clinical trials.
DelMar is also enrolling patients in the trial at four other oncology centers of excellence: The Mayo Clinic Cancer Center in Rochester, MN, The Brain Tumor Center at University of California, San Francisco (UCSF),.; The Sarah Cannon Cancer Research Center in Nashville, TN.; The Sarah Cannon Research Institute affiliate site at the Florida Cancer Specialist Research Institute in Sarasota, FL.; and.

About VAL-083
VAL-083 is a "first-in-class", small-molecule chemotherapeutic. In more than 40 Phase 1 and 2 clinical studies sponsored by the U.S. National Cancer Institute, VAL-083 demonstrated safety and efficacy in treating a number of cancers including lung, brain, cervical, ovarian tumors and leukemia. VAL-083 is approved in China for the treatment of chronic myelogenous leukemia and lung cancer and has received orphan drug designation in Europe and the U.S. for the treatment of gliomas.
DelMar is currently studying VAL-083 in a multi-center Phase I/II clinical trial for patients with refractory glioblastoma multiforme (GBM) in accordance with the protocol that has been filed with the U.S. Food and Drug Administration (FDA). As a potential treatment for glioblastoma, VAL-083’s mechanism of action appears to be unaffected by the expression of MGMT, a DNA repair enzyme that causes chemotherapy resistance to front-line treatment with Temodar (temozolomide).
