Plain English Summary

Background and study aims
Acne is an extremely common skin disease that is found most typically in adolescence and young adulthood. It causes spots, oily skin and sometimes skin that's hot or painful to touch. The aim of this study is to evaluate the effectiveness and acceptance of UP256 cream, 0.5% in the treatment of acne.

Who can participate?
People aged 12-30 with mild to moderate acne

What does the study involve?
Participants are required to follow instructions from the investigator and apply a cream to their face twice a day. The length of the study is 16 weeks and consists of a screening visit, baseline visit (week 0), and treatment visits at weeks 1, 2, 4, 6, 8, 10 and 12. The screening and baseline visit assessment will include an acne lesion count and the first application of the cream by the participant. Treatment visits will also include an evaluation of the response to treatment, a patient questionnaire, acne lesion count, safety assessment, collection of study medication and reporting of adverse events.

What are the possible benefits and risks of participating?
The study does not promise any benefit but a possible benefit could be a clearer complexion. The most common foreseeable adverse events include erythema (redness), irritation and peeling of the skin due to a known mild irritation quality of the topical antibiotics. A risk of participating in the study is that participants are not able to use other acne medication and their condition may worsen.
