Alethia Biotherapeutics Inc., a privately held biotechnology company focusing on the development of therapeutic monoclonal antibodies announced today that it has closed a new financing. Alethia will use the proceeds to fund primarily its lead program. The financing included participation of current major investors comprising AgeChem Venture Fund, BDC Venture Capital and GO Capital in addition to a long-term partner and shareholder of the company, Cellscript of Wisconsin.

"This funding will enable our lead bone antiresorprtive candidate AB-25E9 to advance into the studies required to submit an IND" said Mr. Yves Cornellier, President & CEO of Alethia. "We are very enthusiastic about the potential of this therapeutic monoclonal antibody to address the need for improved therapies within the expanding bone degradation market".

Using its proprietary STAR discovery platform, Alethia has developed a strong pipeline of novel, clinically relevant therapeutic targets that included Siglec-15, an important regulator of osteoclast differentiation and function. In several pathologies, bone remodeling is impaired due to increased osteoclastic activity which leads to decreased bone density and strength. Current antiresorptive therapies reduce osteoclast activity but most also impair bone formation. Alethia's bone antiresoprtive program was purposefully designed to develop a new generation of therapies that decrease osteoclast activity while maintaining bone formation.

Dr. Mario Filion, Chief Scientific Officer of Alethia commented, "We are fortunate to have the continued ongoing support of knowledgeable investors to help the Company advance our AB-25E9 development program into the clinic. Data from pre-clinical in vivo models of bone loss demonstrate that the results obtained with Siglec-15 antibodies are distinctive from those obtained with other anti-resorptive therapies. In particular, inhibition of Siglec-15 resulted in sustained antiresorptive activity coupled with maintenance of bone formation; a profile that, if translated in the clinic, would differentiate this product from currently marketed drugs".
