CombinatoRx

TST Recommends

(CRXX)

fell after the Cambridge, Mass., biotech announced disappointing preliminary results from a midphase study of its proposed treatment for rheumatoid arthritis, CRx-139. The treatment is a combination of prednisolone, an existing anti-inflammatory, and paroxetine, an antidepressant.

The treatment failed the primary endpoint of the trial, which called for a statistically significant difference from prednisolone alone at day 70 as measured by ACR 20 (a 20% improvement in symptoms, according to American College of Rheumatology standards). The testing did reveal that CRx-102 was more effective than prednisolone alone by other measures. Shares of CombinatoRx were down 21 cents, or 2.9%, to $7.05.
