Miransertib (ARQ 092) is an oral, allosteric, selective pan-AKT inhibitor initially developed for cancer therapeutics, now being evaluated for the treatment of PS. After baseline evaluation, the patient started unblinded treatment of 10 mg oral miransertib daily (\u223c5 mg\/m<jats:sup>2<\/jats:sup>\/day), escalated to 30 mg daily (\u223c15 mg\/m<jats:sup>2<\/jats:sup>\/day), and then to 50 mg daily (\u223c25 mg\/m<jats:sup>2<\/jats:sup>\/day) after 3 mo of treatment. Adverse events included dry mouth, one episode of gingivostomatitis, and loose, painful dentition due to preexisting periodontal disease, all of which resolved spontaneously. After 11 mo of treatment, the patient reported improved general well-being, increased mobility of the ankle, spine, and hands, a subjective decrease in size of the right facial bone overgrowth, and reduced areas of cerebriform connective tissue nevi on the soles. Whole-body MRI findings were stable without apparent disease progression. We conclude that 1 yr of treatment with miransertib was beneficial in this case.<\/jats:p>","DOI":"10.1101\/mcs.a004549","type":"journal-article","created":{"date-parts":[[2020,2,3]],"date-time":"2020-02-03T19:45:18Z","timestamp":1580759118000},"page":"a004549","source":"Crossref","is-referenced-by-count":45,"title":["Clinical report: one year of treatment of Proteus syndrome with miransertib (ARQ 092)"],"prefix":"10.1101","volume":"6","author":[{"given":"Leslie G.","family":"Biesecker","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8437-8120","authenticated-orcid":false,"given":"Matthew","family":"Edwards","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheridan","family":"O'Donnell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paula","family":"Doherty","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"MacDougall","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kate","family":"Tith","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Kazakin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2632-6351","authenticated-orcid":false,"given":"Brian","family":"Schwartz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"246","published-online":{"date-parts":[[2020,2,3]]},"reference":[{"key":"2021112406080814000_6.1.a004549.1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ejhg.5201638"},{"key":"2021112406080814000_6.1.a004549.2","unstructured":"Biesecker LG , Sapp JC . 1993.
