OTTAWA, ONTARIO -- (Marketwired) -- 12/13/17 -- Tetra Bio-Pharma Inc. ("Tetra" or the "Company") (TSX VENTURE:TBP)(OTCQB:TBPMF), a global leader in cannabinoid-based drug development and discovery, is pleased to announce that the company has signed an exclusive research and development (R&D) agreement with Constance Therapeutics for the pharmaceutical drug development, and eventual commercialization in Canada, of their standardized, patent-pending, medicinal cannabis extract products. In addition to this agreement, the Company further strengthens its R&D program by means of a National Sciences and Engineering Research Council of Canada (NSERC) grant in its collaborative project with Dr Stan Kubow at McGill university.

Constance Therapeutics has developed whole plant cannabis extracts that have shown significant clinical promise in the treatment of various forms of cancer and improved patient survival as well. In collaboration, Tetra and Constance Therapeutics now aim to define the therapeutic mechanism and demonstrate efficacy of these cannabis extracts in the treatment of human cancers. In accordance with Tetra's provisional patent announced on May 17th, 2017, the collaboration will focus on treating various forms of cancer driven by inappropriate Hedgehog signaling, including multiple forms of brain, blood, skin and bone cancers.

Constance Finley, Founder and CEO of Constance Therapeutics, Inc. said, "over the years, research has demonstrated that cannabinoids including specific terpenes, reduce and inhibit tumor growth in various animal models. Early clinical studies suggest cannabinoids enhance the effects of traditional cancer treatments with radiation therapy and help reduce the size of brain cancers, such as Glioma, compared to controls."

"We are very excited to achieve this co-development program with Constance Therapeutics" added Bernard Fortier, CEO of Tetra. "Their initial research is very promising and we are hopeful that together we can provide novel treatments for multiple forms of aggressive cancer to patients with limited therapeutic options. "

In addition, Tetra is pleased to announce that the company has been awarded an additional Engage Plus grant from the National Sciences and Engineering Research Council of Canada (NSERC) to continue the collaborative project with Dr. Stan Kubow of McGill University. The goal of the basic research project is to explore and develop patentable cannabis-derived retail supplements and drug products in partnership with McGill University, and the grant awarded by NSERC will bolster Tetra Bio-Pharma's investment with matching funds up to a maximum of $12,500.

"We are excited and honored to have the continued support of NSERC on this innovative project with McGill. Through the use of Dr. Kubow's expertise and access to the advanced facility at McGill University, we aim to develop novel natural health supplements and drug products to be commercialized by Tetra," commented Dr. Guy Chamberland, Chief Scientific Officer or Tetra Bio-Pharma.

Together, the co-development project focused on treating Hh-driven disease and the continuation of the McGill collaboration aiming to develop new cannabis-based products diversifies and strengthens Tetra's pre-clinical program, thus ensuring the continuity of the product pipe-line in the future.
