Efficacy was evaluated by counting all inflammatory and non\u2010inflammatory lesions. Safety was evaluated based on adverse events, local skin tolerability scores and laboratory test values. All 609 subjects were randomly assigned to receive the study products (2.5% and 5% <jats:styled-content style=\"fixed-case\">BPO<\/jats:styled-content> and placebo), and 607 subjects were included in the full analysis set, 544 in the per protocol set and 609 in the safety analyses. The median rates of reduction from baseline to the last evaluation of the inflammatory lesion counts, the primary end\u2010point, in the 2.5% and 5% <jats:styled-content style=\"fixed-case\">BPO<\/jats:styled-content> groups were 72.7% and 75.0%, respectively, and were significantly higher than that in the placebo group (41.7%). No deaths or other serious adverse events were observed. The incidences of adverse events in the 2.5% and 5% <jats:styled-content style=\"fixed-case\">BPO<\/jats:styled-content> groups were 56.4% and 58.8%, respectively; a higher incidence than in the placebo group, but there was no obvious difference between the 2.5% and 5% <jats:styled-content style=\"fixed-case\">BPO<\/jats:styled-content> groups. All adverse events were mild or moderate in severity. Most adverse events did not lead to study product discontinuation. The results suggested that both 2.5% and 5% <jats:styled-content style=\"fixed-case\">BPO<\/jats:styled-content> are useful for the treatment of acne vulgaris.<\/jats:p>","DOI":"10.1111\/1346-8138.13798","type":"journal-article","created":{"date-parts":[[2017,3,11]],"date-time":"2017-03-11T08:41:52Z","timestamp":1489221712000},"page":"774-782","source":"Crossref","is-referenced-by-count":10,"title":["Twelve\u2010week, multicenter, placebo\u2010controlled, randomized, double\u2010blind, parallel\u2010group, comparative phase <scp>II<\/scp>\/<scp>III<\/scp> study of benzoyl peroxide gel in patients with acne vulgaris: A secondary publication"],"prefix":"10.1111","volume":"44","author":[{"given":"Makoto","family":"Kawashima","sequence":"first","affiliation":[{"name":"Department of Dermatology Tokyo Women's Medical University Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinichi","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Dermatology Graduate School of Medicine and Faculty of Medicine The University of Tokyo Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fukumi","family":"Furukawa","sequence":"additional","affiliation":[{"name":"Department of Dermatology Wakayama Medical University Wakayama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kayoko","family":"Matsunaga","sequence":"additional","affiliation":[{"name":"Departments of Integrative Medical Science for Allergic Disease Fujita Health University School of Medicine Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hirohiko","family":"Akamatsu","sequence":"additional","affiliation":[{"name":"Department of Applied Cell and Regenerative Medicine Fujita Health University School of Medicine Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atsuyuki","family":"Igarashi","sequence":"additional","affiliation":[{"name":"Dermatology NTT Medical Center Tokyo Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuichiro","family":"Tsunemi","sequence":"additional","affiliation":[{"name":"Department of Dermatology Tokyo Women's Medical University Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobukazu","family":"Hayashi","sequence":"additional","affiliation":[{"name":"Department of Dermatology Toranomon Hospital Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuki","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Dermatology Wakayama Medical University Wakayama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshitaka","family":"Nagare","sequence":"additional","affiliation":[{"name":"Medical Writing Group Data Science Department Maruho Co.
