Brief Summary:
CRx-191 is a proprietary synergistic combination drug candidate being evaluated by CombinatoRx for topical psoriasis therapy. CRx-191 was identified via a proprietary screening assay for novel drug combinations demonstrating enhanced inhibition of tumor necrosis factor- alpha and interferon-gamma release, cytokines that are implicated in the pathogenesis of psoriasis.
