MedImmune, Inc. (MEDI) announced that it has begun dosing rheumatoid arthritis patients with Vitaxin(TM) in a Phase I clinical trial.
Vitaxin is an antibody that has the potential to inhibit the progression of a variety of diseases, including rheumatoid arthritis, psoriasis, psoriatic arthritis, and certain forms of cancer and eye disease. Vitaxin appears to work by binding to a specific integrin (alpha-V-beta-3) expressed on a number of cells, such as newly forming blood vessels (angiogenesis), bone resorbing osteoclasts, and activated macrophages. Both angiogenesis and osteoclast-mediated osteolysis (bone destruction) are key elements involved in the development of rheumatoid arthritis.
"We are very pleased to begin our clinical development for Vitaxin in rheumatoid arthritis," said Dr. Ronald Wilder, MedImmune. "We believe that Vitaxin may have the ability to impede the advancement of this disease by exerting both anti-angiogenic and anti-osteolytic effects through its blocking of alpha-V-beta-3. The data we collect from this trial will complement the research effort we previously initiated with Vitaxin in the cancer ...
