*VALCHLOR (n=119) was assessed in a 12-month randomized, multicenter, observer-blinded, noninferiority study trial (N=260) vs Aquaphor®-based mechlorethamine HCl 0.02%. Primary endpoint: response by CAILS (Composite Assessment of Index Lesion Severity) score (combined scores for erythema, scaling, plaque elevation, and surface area). CAILS ORR: 60% (PR 45% + CR 14%). VALCHLOR noninferiority demonstrated by the rate ratio of 1.24 (95% CI, 0.98, 1.58). ORR (overall response rate) = PR (partial response) + CR (complete response, defined as a score of 0).1,2
VALCHLOR is the first and only FDA-approved topical form of mechlorethamine.1,3
