Kolltan Pharmaceuticals Obtains $60 Million in Series D Financing

Proceeds Will Advance Proprietary Biologic Product Candidates Targeting Receptor Tyrosine Kinases

NEW HAVEN, Conn., March 26, 2014 -- (Healthcare Sales & Marketing Network) -- Kolltan Pharmaceuticals, a privately held biopharmaceutical company focused on the development of novel biologics targeting receptor tyrosine kinases, today announced the completion of a $60 million Series D financing. The financing was led by a new investor, a Boston-based global institutional asset manager, and by an existing investor, KLP Enterprises. Additional new investors participating in this transaction include Deerfield Management, Franklin Berger, and others. Existing investors in the financing include HBM Healthcare Investments Ltd., Purdue Pharma L.P., Osage University Partners, and others.

Kolltan plans to use the proceeds from the Series D financing to advance the Company's lead clinical-stage candidate, KTN3379, into Phase 2 clinical trials in cancer patients suffering from various malignancies. KTN3379 is a novel, dual-mechanism monoclonal antibody that is a potent inhibitor of the ErbB3 receptor tyrosine kinase (RTK). KTN3379's dual mechanism of action ?is designed to block activation of the ErbB3 RTK regardless of whether ErbB3 is being activated by its ligand, neuregulin, or by its association with other RTKs such as ErbB2. KTN3379 is currently being evaluated in a Phase 1 clinical trial to generate data to support the Phase 2 clinical development plan. Kolltan also plans to use the proceeds of the financing to advance preclinical candidates toward IND filing and clinical studies.

"With this strong financial support from both new and current investors, we are able to advance KTN3379 into the evaluation of specific populations of cancer patients where ErbB3 is believed to play an important role in disease pathogenesis," said Jerry McMahon, Ph.D., President and Chief Executive Officer of Kolltan Pharmaceuticals. "In addition, we plan to accelerate the development of two additional undisclosed first-in-class biologic product candidates, while continuing to fund our ongoing earlier-stage research programs."

"Kolltan has assembled an experienced executive team and distinguished board of directors known for their scientific and operational excellence and accomplishments. Furthermore, the team has a track record of successful product development from discovery through commercialization and the creation and return of value to shareholders," said Kolltan Co-Founder and Chairman, Arthur Altschul, Jr. "This financing provides Kolltan with funding to advance multiple differentiated product candidates through significant milestones in clinical as well as preclinical development, to continue to develop our innovative research pipeline, and to create opportunities to fund or partner our clinical-stage assets."
