Avila Therapeutics Presents New Btk Inhibitor Data at Federation of Clinical Immunology Societies Meeting, FOCIS 2010
Clinical Candidate, AVL-292, Demonstrates Efficacy in Preclinical Models of Rheumatoid Arthritis
BOSTON & WALTHAM, Mass.--(BUSINESS WIRE)--Jun 28, 2010 - Avila Therapeutics™, Inc., a biotechnology company developing targeted covalent drugs that treat diseases through protein silencing, today announced results of preclinical studies demonstrating that its clinical candidate, AVL-292, potently inhibits B cell receptor signaling, and demonstrates efficacy in a rodent model of rheumatoid arthritis. These new data were presented Saturday, June 26, 2010 at the Federation of Clinical Immunology Societies (FOCIS) 2010 annual meeting in Boston, MA.
AVL-292 is a novel, orally available, covalent drug that targets Bruton's tyrosine kinase (Btk). Inhibition of Btk is a promising new approach to treatment of diseases that are driven by B cells, which are part of the immune system. AVL-292 bonds selectively and covalently with Btk to shut down and silence its activity. This unique mechanism of action confers greater target selectivity and a longer duration of action than is typical of conventional small molecule drugs.
Btk plays a crucial role in the activation of normal B lymphocytes and contributes to the proliferation and survival of B cell lymphomas. AVL-292, with its ability to irreversibly inhibit and silence Btk, may represent a new best-in-class therapeutic option for the treatment of autoimmune diseases such as rheumatoid arthritis, as well as B cell-related hematological cancers, including non-Hodgkin lymphoma (NHL) and B cell chronic lymphocytic leukemia (B-CLL).
In an oral presentation at FOCIS entitled “A Novel Covalent Inhibitor of Btk Inhibits B Cell Receptor Signaling and Demonstrates Efficacy in CIA Rheumatoid Arthritis Model”, Erica Evans, Ph.D., Senior Scientist, Avila Therapeutics, presented data from preclinical studies that evaluated the efficacy of AVL-292 in the mouse collagen-induced arthritis model. Highlights of the data demonstrate:
”We are excited to share these data with the clinical and research community at FOCIS,” said Juswinder Singh, Ph.D., Avila's Founder and Chief Scientific Officer. “These results show very profound disease-modifying effects of AVL-292 in both prophylactic and therapeutic models of rheumatoid arthritis. In conjunction with the safety testing Avila Therapeutics has completed, the efficacy data provide exciting validation for this program as we advance AVL-292 into clinical studies this year.”
About Covalent Drugs
The covalent bonding mechanism of Avila Therapeutics' drugs has unique properties to effectively ˜silence' disease-causing proteins. Avila drugs establish a strong and enduring ˜bond' – exceeding the more temporary ˜binding' of conventional drugs – to completely shut down the activity of, and silence, a disease-causing protein. Avila's covalent drugs have unique therapeutic benefits because they are exquisitely targeted, are effective against mutations and have long duration of action.
About Avila Therapeutics™, Inc.
Avila focuses on design and development of targeted covalent drugs to achieve best-in-class outcomes that cannot be achieved through traditional chemistries. This approach is called “protein silencing”. The company's product pipeline has been built using its proprietary Avilomics™ platform and is currently focused on viral infection, cancer and autoimmune disease. Avila is funded by leading venture capital firms: Abingworth, Advent Venture Partners, Atlas Venture, Novartis Option Fund, and Polaris Venture Partners.
