DelMar Pharmaceuticals Announces Issuance of New Patent on First-in-Class DNA-targeting Agent, VAL-083

VANCOUVER, British Columbia and MENLO PARK, Calif., Sept. 20, 2017 /PRNewswire/ -- DelMar Pharmaceuticals, Inc. (Nasdaq: DMPI) ("DelMar" and "the Company"), a biopharmaceutical company focused on the development of new cancer therapies, today announced that the U.S. Patent and Trademark Office (USPTO) has issued to DelMar, United States Patent No. 9,759,698 covering improved analytical methods for analyzing and determining impurities in dianhydrogalactitol (VAL-083).

DelMar's new patent strengthens the Company's control over the VAL-083 manufacturing process and related controls. DelMar is establishing broad new intellectual property protection around VAL-083, a first-in-class DNA targeting agent that demonstrated clinical activity against a range of tumor-types in prior clinical trials sponsored by the U. S. National Cancer Institute (NCI).   

VAL-083 is currently protected by eight US patents and eight patents outside of the US, with issued claims providing patent protection into 2033 in the United States.  DelMar has made patent filings under 14 separate patent families encompassing more than 100 individual patent applications. 

About DelMar Pharmaceuticals, Inc.

DelMar Pharmaceuticals is focused on the development and commercialization of new therapies for cancer patients who have limited or no treatment options.  By focusing on understanding tumor biology and mechanisms of treatment resistance, the Company identifies biomarkers to personalize new therapies in indications where patients are failing, or have become intolerable to modern targeted or biologic treatments.

The Company's current pipeline is based around VAL-083, a "first-in-class," small-molecule chemotherapeutic with a novel mechanism of action that has demonstrated clinical activity against a range of cancers including central nervous system, ovarian and other solid tumors (e.g. NSCLC, bladder cancer, head & neck) in U.S. clinical trials sponsored by the NCI.  Based on DelMar's internal research programs and these prior NCI-sponsored clinical studies, the Company is conducting clinical trials to support the development and commercialization of VAL-083 across multiple oncology indications to solve significant unmet medical needs.

The STAR-3 trial is a multi-center, pivotal, randomized Phase 3 clinical study in bevacizumab (Avastin®) recurrent GBM. Outcomes in DelMar's recent Phase 1-2 clinical trials suggest that VAL-083 may offer a clinically meaningful survival benefit for this patient population.

VAL-083 is also being studied in two collaborator-supported, biomarker driven, Phase 2 clinical trials for MGMT-unmethylated GBM as a potential treatment alternative for the majority of GBM patients whose tumors exhibit high expression of MGMT, a biomarker correlated with resistance to the current standard-of-care chemotherapy.   Overcoming MGMT-mediated resistance represents a significant unmet medical need in the treatment of GBM.

The VAL-083 REPROVe trial will explore VAL-083 in platinum-resistant ovarian cancer.  Resistance to platinum-based chemotherapy represents a significant unmet medical need in the treatment of ovarian cancer.
