TORONTO, ON--(Marketwired - Dec 23, 2016) - Helix BioPharma Corp. (“Helix” or the “Company”) ( TSX : HBP ) ( FRANKFURT : HBP ), a clinical-stage, immuno-oncology company developing innovative drug candidates for the prevention and treatment of cancer, announces today it has signed an exclusive out-license agreement with Xisle Pharma Ventures Trust (“Xisle”) for the Company’s late-stage, Biphasix™ technology platform, including the lead product candidate, interferon alpha. Xisle will be responsible for the continued clinical development and subsequent commercialization of the product for the treatment of HPV-induced, low-grade, cervical intraepithelial lesions. As part of its asset development strategy, Xisle has initiated collaboration with senior pharmaceutical executives at Altum Pharmaceuticals Inc., who possess extensive regulatory, clinical, and product development expertise.
Under the terms of the agreement, Xisle has paid an up-front fee and agreed to subsequent milestone payments as they advance the technology to registration and market approvals. Helix has retained marketing rights for certain territories. EVOLUTION Life Science Partners LLC, a division of Gordian Investments, LLC acted as advisor to Helix BioPharma Corp.
“This is an important milestone for Helix as it represents our ability to take a novel immunotherapy asset from discovery to out license,” said Dr. Sven Rohmann, Chief Executive Officer for Helix. Dr. Rohmann added that, “We can now fully concentrate our financial and development efforts on advancing our clinical stage Tumor Defense Breaker and newest CAR-T program aimed at solid tumors.”
About The Biphasix™ Topical Formulation System
The Biphasix™ Topical Formulation System is a platform technology for microencapsulating therapeutic compounds in multilayered, lipid-based microvesicles. These microvesicles have complex structures that include a variety of compartments into which drug molecules can be integrated. The principal application of the technology is in the preparation of topical dosage forms for the dermal (into the skin) or mucosal (into the mucosal tissues) delivery of large molecular weight drug compounds.
About Topical Interferon Alpha-2b
Topical Interferon Alpha-2b incorporates Helix’s patented Biphasix™ drug delivery technology. It is a topical preparation that is intended to be easily self-applied to HPV-infected tissues, to deliver interferon alpha-2b into the skin and mucosal tissues.
About L-DOS47
L-DOS47 is Helix’s first immunoconjugate-based drug candidate in development is based on Helix’s novel DOS47 technology platform which the Company believes alters the tumor microenvironment from acidic to alkaline. The Company believes L-DOS47 represents an innovative approach in modifying the microenvironmental conditions of cancer cells which the Company also believes serves as a general defense against cancer drugs and immunotherapies. Breaking the tumor defense by changing the tumor micro environment from acidic to alkaline represents one of the forgotten hallmarks of cancer. L-DOS47 is intended to offer an innovative approach to the first-line treatment of inoperable, locally advanced, recurrent or metastatic non-small cell lung cancer (“NSCLC”). L-DOS47 is currently being evaluated in two clinical studies, one in the United States (“LDOS001") and the other in Poland (“LDOS002").
About CAR-T
The Company is leveraging its know-how in manipulating the tumor microenvironment, and its expertise in developing unique single domain antibody therapeutics to develop Chimeric Antigen Receptors (“CAR”) for engineered T cell based treatment (“CAR-T”). CAR-T is a novel cell based treatment that uniquely leverages the patient’s immune system to treat cancer. In one application, the patient’s T cells are isolated and then transformed with specific CAR that recognize the cancer. The transformed T cells or CAR-Ts are infused back into the patient to affect the treatment. The Company has selected CEACAM6 and VEGFR2 specific CARs for treatment of solid tumors in several unmet medical indications. In addition, the Company’s research program has selected CD19 and CD22 targets for hematological cancers.
