Introduction: The main goal of acne treatment is to clear lesions quickly to manage and/or mitigate sequelae. Topical clindamycin phosphate 1.2%/adapalene 0.15%/benzoyl peroxide 3.1% (CAB) gel is the only fixed-dose, triple-combination approved for acne. In three published clinical studies of participants with moderate to severe acne, CAB gel demonstrated superior efficacy to vehicle and component dyads, with good safety/tolerability. Herein are presented detailed efficacy and safety data from 5 clinical study patients to document their CAB treatment journey. Methods: In two phase 3 (NCT04214652, NCT04214639), double-blind, 12-week studies, participants aged ≥9 years with moderate-to-severe acne were randomized to once-daily CAB or vehicle gel. Endpoints included percentage of participants achieving treatment success (≥2-grade reduction from baseline in Evaluator’s Global Severity Score and clear/almost clear skin) and percent change from baseline in inflammatory/ noninflammatory lesion counts. Dosing compliance, treatment-emergent adverse events (TEAEs) and cutaneous safety/tolerability were also assessed. Descriptive data from 5 selected cases who completed 12 weeks of CAB treatment are summarized. Results: Participants (n=5) ranged from 13-32 years. At week 12, 3 achieved treatment success, 1 achieved a 2-grade reduction from severe to mild, and 1 achieved a 1-grade reduction from moderate to mild. Reductions from baseline to week 12 in inflammatory/ noninflammatory lesion counts ranged from 74.7-100%. No participants reported TEAEs/serious AEs. Some cutaneous safety/tolerability scores increased at weeks 2, 4, or 8, but generally decreased back to/below baselines levels by week 12, similar to the overall study populations. Most scores at week 12 were 0 (none) or 1 (mild), with only one participant reporting scores of 2 (moderate) for itching, burning, and stinging. Conclusions: In the overall phase 3 clinical trials, fixed-dose, triple-combination CAB gel has demonstrated good efficacy, safety, and tolerability. All 5 cases presented here achieved substantial (&gt;70%) acne lesion reductions, with 4/5 cases achieving treatment success or a 2-grade EGSS reduction by week 12. While patterns in cutaneous safety/tolerability were variable across cases, transient increases with CAB generally resolved to baseline values within two months of treatment. These clinical study cases reinforce the importance of patient education regarding efficacy and safety of acne treatment, including the importance of treatment adherence, managing patient expectations, and the potential for cutaneous effects, which are often transient.
