Antibodies against CCAR1 confer protection against cancer

Researchers at Stanford University and Johns Hopkins University have identified an antibody that is negatively associated with cancer in patients diagnosed with dermatomyositis. Although anti-TIF1-?-positive dermatomyositis patients have an increased risk of cancer compared to the general population, a substantial subgroup either never develop cancer or have less aggressive diagnoses. In their study, antibodies against CCAR1 were present in a third of anti-TIF1-?-positive patients, and was significantly negatively associated with cancer diagnosis within three years of the first onset of dermatomyositis symptoms. The inventors are in the process of developing ELISA diagnostic screens for anti-CCAR1 towards clinical and commercial use.

Stage of Development
The inventors have developed a prototype of a cancer-screening assay that uses the identified antibody and are working towards optimizing the method for clinical and commercial use.
