Efficacy and safety of a novel triple combination cream compared to Kligman & apos;s trio for melasma: A 24-week double-blind prospective randomized controlled trial

Background Kligman's trio (KT), combining hydroquinone, retinoic acid and corticosteroid, is considered as the gold standard treatment of melasma. Its efficacy has never been matched before, but it is tempered by frequent adverse effects.Objective To assess the efficacy and tolerance of a New Trio (NT) combination with isobutylamido-thiazolyl-resorcinol, retinoic acid and cortosteroid compared to KT.Methods We conducted a 24-week monocentric trial, randomized, double-blind, controlled versus KT, with 40 melasma patients. NT and KT were applied for 12 weeks and associated with the same sunscreen applied for 24 weeks. The primary endpoint was the modified Melasma Area Severity Index (mMASI) at 12 weeks. Patient quality of life was investigated using MelasQoL.Results After 12 weeks, KT and NT groups both demonstrated a significant improvement in mMASI, respectively -2.84 (SE 0.69, p < 0.0002) and -4.33 (SE 0.71, p < 0.0001). The mean difference between the two groups was -1.49 (IC 95% -3.52 to 0.54, p = 0.14). MelasQoL improvement was -6.66 (SE 3.29, p = 0.0515) with KT and -12.57 (SE 3.29, p = 0.0006) with NT.Conclusion The NT combination appears to be an effective treatment option for treating melasma and could be considered as a well-tolerated alternative to KT.

Automated summary

This study aimed to assess the efficacy and tolerance of a New Trio (NT) combination compared to Kligman's trio (KT) in treating melasma. The results showed that both the NT and KT groups demonstrated significant improvement in mMASI after 12 weeks, with the NT group showing a more significant improvement. Therefore, the NT combination can be considered as an effective treatment option for melasma with better tolerance.
