Last verified: November 2007
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.

Condition Intervention Phase
Drug: CRx-191
Drug: mometasone furoate
Drug: nortriptyline HCl
Drug: Karison® Creme
Drug: Vehicle
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Phase I, Single-Center, Randomized, Vehicle and Active-Controlled Study to Assess and Compare the Atrophy-Causing Potential of Topical CRx-191 Formulations in Healthy Volunteers

Further study details as provided by Zalicus:

Primary Outcome Measures:
  • Full skin thinning produced by treatment of CRx-191 in comparison with its components at corresponding dose levels, and vehicle with a marketed corticosteriod. Assess tolerability and safety of CRx-191. [ Time Frame: 28 Days ]
