Cangene acquires Twinstrand Therapeutics Inc

Cangene Corporation today announces that it has acquired all issued and outstanding shares of privately held Twinstrand Therapeutics Inc. ("Twinstrand"). Cangene has paid $1.5 million (subject to post-closing adjustments) to acquire Twinstrand which has products, technologies and financial attributes including those related to tax. Twinstrand has established a technology that uses modified versions of ricin, a plant-derived cell toxin, as therapeutic prodrugs. Its lead drug, a product known as TST10088, is currently undergoing a Phase I clinical trial. The prodrugs leave healthy cells unaffected while specific chemical activity within targeted diseased cells activates the cell-killing activities of the drug. As a spin-off from its original focus, Twinstrand has also begun developing anti-ricin, antibody-based therapeutics; Cangene has partnered with Twinstrand on this technology in the past. The acquisition of Twinstrand includes an obligation that Cangene pay to certain of Twinstrand's former investors a royalty on any commercial sales of antibody products related to TST10088 that may be developed, as well as a royalty on any associated licensing fees.

"This acquisition is in line with our on-going interest in augmenting our commercial pipeline and biodefence products through the acquisition of complementary products or technologies," said Dr. John Langstaff, Cangene's president and CEO.

Twinstrand is a private clinical-stage biopharmaceutical company dedicated to the discovery and development of biological drugs for the treatment of life-threatening diseases. Its pipeline includes products with applications in cancer; viral, parasitic and fungal diseases; and biodefence. Cangene plans on winding-up Twinstrand and integrating its activities into Cangene's operations.
