EFFICACY EVALUATION
The maintenance rates for total, inflammatory, and non- inflammatory lesion counts at the study end point (week 16, ITT population, worst case) are shown in Figure 2.
These rates reflect the percentage of subjects maintaining at least 50% improvement from the previous combina-tion study; missing data were treated as treatment fail- ures. Continued treatment with adapalene gel, 0.1%, re- sulted in significantly higher maintenance rates in total lesion counts (75% vs 54%; PϽ.001), inflammatory le- sion counts (74% vs 57%; P=.003), and noninflamma- tory lesion counts (71% vs 55%; P=.007) compared withtreatment with vehicle (Figure 2).
To our knowledge, no formal definition of acne main- tenance currently exists, and therefore this was the first studyfor which this definition of maintenance was used (main- Figure 2. Maintenance rates (percentage of subjects maintaining at least

parameters were all less than 1 (mild) as well. Most sub- jects in both groups experienced mild or no irritation.
The number of subjects experiencing adverse events was similarinbothtreatmentgroups,with25%and23%reported for the adapalene and vehicle groups, respectively. During the course of the study, treatment-related adverse events occurred in 3 (2.4%) of adapalene-treated subjects and 1 (0.8%) of vehicle-treated subjects. The most common treatment-related adverse event was pruritus (2 subjects, possibly related). One subject experienced a serious adverse event deemed unrelated to study treatment (suicide attempt by subject with a history of depression). There were no ad- verse events that led to a study discontinuation, and all treatment-related adverse events were mild in severity.
SUBJECT SURVEY
The results from the 5-question survey are illustrated in Figure 6. Most subjects in both treatment groups were
not bothered by adverse effects (90% in both the ada- palene and vehicle groups; P=.94). Significantly more sub- jects in the adapalene group than in the vehicle group were “very satisfied” or “satisfied” with the treatment effective-ness (75% vs 58%; P=.003) and the overall maintenance treatment (76% vs 65%; P=.01). Similarly, when subjects were asked how they regarded the overall treatment scheme beginning with the combination therapy, a significantly larger percentage of subjects receiving adapalene mainte- nance therapy were “very satisfied” or “satisfied” com- pared with subjects receiving vehicle (84% vs 73%; P=.02).
