DelMar Pharmaceuticals Announces Successful Completion of End-of-Phase 2 Meeting with FDA on VAL-083 for the Treatment of Refractory Glioblastoma Multiforme

VANCOUVER, British Columbia and MENLO PARK, Calif., May 25, 2016 /PRNewswire/ -- DelMar Pharmaceuticals, Inc. (OTCQX: DMPI) ("DelMar" and the "Company"), a company focused on developing and commercializing proven cancer therapies in new orphan drug indications, today announced the successful completion of an End of Phase 2 meeting with the U.S. Food and Drug Administration (FDA).

"Our End-of-Phase 2 meeting was an important milestone for the Company as we advance the clinical development of VAL-083," stated Jeffrey Bacha, chairman and CEO of DelMar Pharmaceuticals.  "We are pleased with the FDA's guidance on our Phase 3 trial design in patients with glioblastoma who have failed prior therapy with temozolomide and bevacizumab (Avastin^®), and we look forward to finalizing the trial design and initiating the study as quickly as possible."

DelMar's advanced development program will feature a single randomized Phase 3 study measuring survival outcomes compared to a "physicians' choice" control, which, if successful, would serve as the basis for a New Drug Application (NDA) submission for VAL-083.   The control arm will consist of a limited number of salvage chemotherapies currently utilized in the treatment of Avastin-failed GBM. The final pivotal trial design will be confirmed with the FDA following further discussions with the Company's clinical advisors.  

The FDA confirmed that it will consider the totality of data available, including data obtained from DelMar's other planned clinical trials in related GBM populations, when assessing the NDA.  The FDA also noted that DelMar can rely on prior US National Cancer Institutes (NCI) studies and historical literature to support non-clinical data required for an NDA filing and that DelMar will have the option to file under a 505(b)(2) strategy, which allows a sponsor to rely on already established safety and efficacy data in support an NDA.

"There is a major unmet medical need in refractory glioblastoma," said Mr. Bacha.  "The encouraging data from our clinical trials to date, combined with historical data from prior clinical trials from the NCI, suggest that VAL-083 has the potential to improve therapeutic outcomes for GBM patients who currently have no viable treatment options.  We are now one step closer to achieving that goal."

About VAL-083

VAL-083 is a "first-in-class," small-molecule chemotherapeutic. In more than 40 Phase I and II clinical studies sponsored by the U.S. National Cancer Institute, VAL-083 demonstrated clinical activity against a range of cancers including lung, brain, cervical, ovarian tumors and leukemia both as a single-agent and in combination with other treatments. VAL-083 is approved in China for the treatment of chronic myelogenous leukemia (CML) and lung cancer, and has received orphan drug designation in Europe and the U.S. for the treatment of malignant gliomas.  DelMar recently announced that the USFDA's Office of Orphan Products had also granted an orphan designation to VAL-083 for the treatment of medulloblastoma. 

DelMar has demonstrated that VAL-083's anti-tumor activity is unaffected by the expression of MGMT, a DNA repair enzyme that is implicated in chemotherapy resistance and poor outcomes in GBM patients following standard front-line treatment with Temodar^® (temozolomide).

DelMar conducted a Phase I/II clinical trial in GBM patients whose tumors have progressed following standard treatment with temozolomide, radiotherapy, bevacizumab and a range of salvage therapies.  Patients were enrolled at five clinical centers in the United States: Mayo Clinic (Rochester, MN); UCSF (San Francisco, CA) and three centers associated with the Sarah Cannon Cancer Research Institute (Nashville, TN, Sarasota, FL and Denver, CO) (clinicaltrials.gov identifier: NCT01478178). DelMar announced the completion of enrollment in a Phase II expansion cohort in September, 2015.

About Glioblastoma Multiforme (GBM)

Glioblastoma multiforme (GBM) is the most common and most malignant form of brain cancer. Approximately 15,000 people are diagnosed with GBM each year in the U.S., with similar incidence in Europe. Standard of care is surgery, followed by either radiation therapy, or radiation therapy combined with temozolomide. Approximately 60 percent of GBM patients treated with temozolomide experience tumor progression within one year. More than half of glioblastoma patients will fail the currently approved therapies and face a very poor prognosis.

About DelMar Pharmaceuticals, Inc.

DelMar Pharmaceuticals, Inc. was founded to develop and commercialize new cancer therapies in indications where patients are failing or have become intollerant to modern targeted or biologic treatments. The Company's lead drug in development, VAL-083, is currently undergoing clinical trials in the U.S. as a potential treatment for refractory glioblastoma multiforme. VAL-083 has been extensively studied by the U.S. National Cancer Institute, and is currently approved for the treatment of chronic myelogenous leukemia and lung cancer in China. Published pre-clinical and clinical data suggest that VAL-083 may be active against a range of tumor types via a novel mechanism of action that could provide improved treatment options for patients.
