These growths appear as thickened, often darker areas of skin that form lines or swirls. On the arms and legs, they usually appear as straight streaks, while on the trunk and face they follow curved patterns called the lines of Blaschko, which reflect how skin cells develop before birth.\n\nThese skin changes are caused by specific genetic changes that turn on certain cell growth pathways inside skin cells. Most linear verrucous epidermal nevi involve one of two major pathways that control cell growth: the PI3K\u002FAKT\u002FmTOR pathway or the RAS\u002FMAPK pathway. In more than 40% of cases, changes in the FGFR3 or PIK3CA genes cause constant activation of the PI3K\u002FAKT\u002FmTOR pathway, leading to excess skin growth.\n\nSirolimus (also called rapamycin) is a medication that blocks the mTOR pathway, slowing down cell growth and protein production. Medications like this are already used to treat certain cancers caused by overactive mTOR signaling.\n\nTopical sirolimus is FDA-approved as a 0.2% gel (Hyftor) to treat facial angiofibromas in people with tuberous sclerosis complex (TSC). In TSC, genetic changes cause the mTOR pathway to be overly active, leading to skin growths called angiofibromas. Studies have shown that applying sirolimus to the skin can reduce the size and visibility of these lesions.",[32],{"label":33,"type":34,"description":23,"interventionNames":35},"Patients 6 years of age or older with a non-inflammatory epidermal nevi","EXPERIMENTAL",[36],"Drug: sirolimus topical gel 0.2%",[38],{"type":39,"name":40,"description":41,"armGroupLabels":42,"otherNames":43},"DRUG","sirolimus topical gel 0.2%","Topical sirolimus will be applied twice daily to the nevi with a maximum daily dose of 600 mg for patients 6-11 years of age and 800 mg for patients 12 years and older.",[33],[44],"Hyftor",[46],{"name":47,"affiliation":5,"role":48},"Amy Paller, MD","PRINCIPAL_INVESTIGATOR",[50],{"name":51,"role":52,"phone":53,"phoneExt":23,"email":54},"Dermatology CTU","CONTACT","312-503-5944","NUderm-research@northwestern.edu",[56],{"facility":57,"status":23,"city":58,"state":59,"zip":60,"country":61,"countryCode":62,"cosmosGeoPoint":63,"geoPoint":68,"contacts":23},"Northwestern University Feinberg School of Medicine, Department of Dermatology","Chicago","Illinois","60611","United States","US",{"type":64,"coordinates":65},"Point",[66,67],-87.65005,41.85003,{"lat":67,"lon":66},{"type":48,"investigatorFullName":70,"investigatorTitle":71,"investigatorAffiliation":5,"oldNameTitle":23,"oldOrganization":23},"Amy Paller","Professor","100655371","early-phase-1-a-pilot-study-to-examine-the-efficacy-and-tolerability-of-sirolimus-on-epidermal-nevi-lesions-in-patients-6-years-old-and-above-100655371",false,"NCT07813533","A Pilot Study to Examine the Efficacy and Tolerability of Sirolimus on Epidermal Nevi Lesions in Patients 6 Years Old and Above.","Inclusion Criteria:\n\n* Patients 6 years of age or above with a non-inflammatory epidermal nevi\n* Lesion(s) that have been present for at least 3 years and are relatively stable\n* At least 2 cm in length (ideally continuous, but can be cumulatively)\n* The lesions is raised, hyperpigmented compared to the surrounding skin, and is noninflammatory with a physician global assessment (PGA) of at least 3 (moderate).\n* Agree to avoid emollient use at the nevus site throughout the study\n* Agree to not bath or shower 2 hours post-application, knowing that the gel can be applied after bathing or showering.\n\nExclusion Criteria:\n\n* Patients currently or recently (within past 4 weeks) using a topical keratolytic or topical anti-inflammatory medication at the lesional site (i.e. topical steroid, topical retinoid, alpha-OH acid)\n* Pregnant or planning to become pregnant during the course of the study","ALL","6 Years",{"count":81,"type":82},14,"ESTIMATED","INTERVENTIONAL",[85],"EARLY_PHASE1","We hypothesize that topical sirolimus could suppress the mTOR activation of linear verrucous epidermal nevi, particularly when the variants are involving genes upstream of mTOR and perhaps even those of the RAS pathway through crosstalk and downstream signaling.
