Opsona Therapeutics Limited raises €33 million Series C equity financing to advance clinical development of its lead product OPN-305.

April 29th, 2013, Dublin, Ireland – Opsona Therapeutics Limited, the innate immune drug development company, today announced that it has raised €33 million (US $43 million) in a Series C financing. The participants in this Series C financing include existing investors, Novartis Venture Fund, Fountain Healthcare Partners, Roche Venture Fund and Seroba-Kernel Life Sciences. The new investors joining the consortium are BB Biotech Ventures, Sunstone Capital, Baxter Ventures, Amgen Ventures, and EMBL Ventures. BB Biotech Ventures led the Series C financing round and will be joining the board of directors together with Sunstone Capital and Baxter Ventures.

The company will use the proceeds to conduct a two-part multi-centered, double blinded and placebo controlled clinical study to evaluate the safety, tolerability and efficacy of its lead product OPN-305 in renal transplant patients at high risk of Delayed Graft Function (DGF). This is the first clinical indication for OPN-305 Opsona’s lead product, a fully human monoclonal IgG4 antibody targeting Toll-like-receptor-2 (TLR-2).

Opsona recently completed a successful Phase I clinical trial in healthy human volunteers and has also demonstrated activity in preclinical animal models and ex-vivo studies. This first-in-class inhibitor of TLR-2 has the advantage of inhibiting multiple cytokines leading to the pathogenesis of the complex inflammatory response in various diseases (ischemia/reperfusion injuries, rheumatoid arthritis, diabetes, lupus, nephritis and various cancers).

Dr. Martin Welschof, CEO of Opsona, commented: “The innate immune system represents a new frontier in targeting inflammatory diseases, and the caliber of venture and corporate investors in this funding round is a demonstration of Opsona’s expertise and capabilities in this highly promising field. With their repeat investment, our existing investors have clearly indicated their long-term commitment to Opsona, while the new investment from BB Biotech Ventures, Sunstone Capital, Baxter Ventures, Amgen Ventures and EMBL Ventures is a further endorsement of Opsona’s future potential.”

Dr. Martin Muenchbach, Managing Director at BB Biotech Ventures, added: “We are delighted to be working with Opsona Therapeutics and the other investors, and are excited to further advance Opsona’s lead product OPN-305 into a well-designed Phase II efficacy study to improve post-operative complications in renal transplantation, an indication with major unmet medical need and attractive commercial potential. This high-quality study (double-blinded, placebo-controlled, and multi-center) with clinically meaningful endpoints will also be of relevance for a subsequent Phase III registration study.”
