Rheumatoid Arthritis and Psoriasis Trials for Vitaxin Halted
Vitaxin targets the alpha-v beta-3 integrin, which is a protein expressed on the surface of newly forming blood vessels, certain tumor types and on a number of other cell types, including macrophages and osteoclasts. Based on preclinical models, the alpha-v beta-3 integrin has been implicated in a number of disease processes, including the growth and metastasis of tumors, the bone destruction in RA and the inflammatory process in psoriasis.
