XToll, a recombinant chaperonin 10 as an anti-inflammatory immunomodulator.

CBio Ltd, under license from the University of Queensland, is developing a recombinant form of chaperonin 10, known as XToll, for the potential anti-inflammatory treatment of rheumatoid arthritis, psoriasis and multiple sclerosis. All three indications have been evaluated in phase IIa clinical trials. By May 2005, a phase IIa trial for Crohn's disease had been terminated due to slow recruitment. The company has not disclosed plans for future development for this indication.
