Introduction!#!Daily parallel application of adapalene and nadifloxacin has been determined to be effective and well tolerated in patients with acne vulgaris in randomized, controlled clinical studies. Here, the authors report the results from a large, prospective, uncontrolled, multicentric, noninterventional study under real-life conditions in Germany. The effect of treatment on acne severity, safety, and, for the first time, health-related quality of life (HRQoL) was investigated.!##!Methods!#!Of the 292 patients (safety collective: 231 adults, 61 adolescents) who had at least grade 4 acne vulgaris on the face as per the Leeds Revised Acne Grading (LRAG), 273 (efficacy collective: 213 adults, 60 adolescents) were treated with adapalene 0.1% cream or gel and nadifloxacin 1% cream for the defined minimum of 28 days. Patients were evaluated for acne severity, acne-related facial symptoms, HRQoL, overall assessment of therapy, and safety.!##!Results!#!After the median treatment duration of 37 and 38 days (adults and adolescents, respectively), 93.4% and 85.0% of adults and adolescents, respectively, exhibited a sustained decrease in acne severity. The LRAG decreased by at least 3 scores in 29.1% and 24.6% of female and male adults, respectively. HRQoL improved in 67.9% and 63.5% of adults and adolescents, respectively (median improvement in the Dermatology Life Quality Index scores per patient of 3.0 [female adults], 1.0 [male adults], and 2.0 for all adolescents in the Children's Dermatology Life Quality Index). Female adults were more impaired in terms of HRQoL compared to male adults. The 2 best overall efficacy ratings were provided by physicians in 79.3% and 69.5% and by patients in 68.5% and 58.3% of adult and adolescent cases, respectively. The treatment was well tolerated, as reflected in the low number of 9 mild adverse events (AEs), all of which resolved without treatment. However, 4 patients terminated the study prematurely due to AEs.!##!Conclusion!#!In this study, the parallel use of adapalene and nadifloxacin for at least 5 weeks resulted in a rapid improvement in acne severity, an increase in HRQoL, and a good safety profile. Therefore, it represents a promising treatment option that offers the possibility of flexible therapy adjustment.
