Tolera Therapeutics Inc., a privately held biotechnology company focusing on the development of immunotherapeutics directed at the transplantation, autoimmune and oncology markets, announced today that it has closed its Series B-3 financing. Hopen Life Science Ventures of Grand Rapids, Michigan led the round and was joined by other current investors including Triathlon Medical Venture Partners and SWMF Life Science Fund.

"This funding provides support to close out Phase 2 activities and preparation for Phase 3 investigation of TOL101, our lead clinical candidate," said CEO John Puisis . "We are excited to bring this novel T-cell targeting biologic drug to market where there is a significant need for new immune modulating strategies and few, if any, industry pipeline alternatives."

Tolera is planning to submit a Special Protocol Assessment (SPA) with the U.S. Food and Drug Administration (FDA) for its Phase 3 clinical trial comparing TOL101 to Thymoglobulin, the current market leading induction agent, for prevention of acute organ rejection. The FDA Special Protocol Assessment process allows sponsors to seek FDA acceptance of a Phase 3 protocol design, prior to conducting a study to support efficacy claims to be submitted as part of a Biologics Licensing Application (BLA) or New Drug Application (NDA).

Mark Olesnavage , managing director, Hopen Life Science Ventures and a member of the Tolera Board of Directors added: "We are pleased to lead this funding round for Tolera, a company with promising technology and a nearer-term market opportunity. Our Phase 2 data has demonstrated key advantages in transplantation, and we look forward to the Phase 3 investigation and ultimate market approval of this novel immune targeting agent."

CEO Puisis continued, "We are pleased by the continuing support of our investors as well as the clinical investigators we have been working with, who continue to confirm the significant unmet need for an alternative induction agent."
