简要总结

This proof-of-concept trial evaluates the efficacy, safety, and patient satisfaction of topical minocycline foam (AMZEEQ®) in patients aged 9 and older with confluent and reticulated papillomatosis (CARP). Participants will apply AMZEEQ® to one side of the body and a topical emollient to the other for 5 weeks, followed by an optional extension period. The study aims to assess whether topical minocycline is a well-tolerated and effective alternative to oral antibiotics.

详细描述

Confluent and reticulated papillomatosis (CARP) is a dermatologic condition consisting of primarily truncal hyperpigmented and hyperkeratotic papules and macules in adolescents. The exact cause is unclear, though a gram-positive actinomycete, Dietzia papillomatosis, likely plays a role. Resolution of the rash could take a year or even years to fully occur. While the gold-standard is to treat with oral minocycline (100 mg daily), preliminary data suggests that topical minocycline may be effective as well. A case report of a 51-year-old female documents clearance with topical minocycline foam. Other antibiotics can be considered as well, such as azithromycin and erythromycin. Antifungal medications can also be considered as well as topicals such as tretinoin, tacrolimus, and urea.

Oral minocycline has a number of side effects and cannot be used in pregnancy. Given side effects and risks of lengthy oral antibiotic treatment, investigators believe that utilization of topical minocycline foam could be a suitable option for patients, especially those who do not want to be treated with oral minocycline for an extended period of time.

结局指标

主要结局

Change in analog score based on blinded reviewer analysis of individuals treated with both daily topical AMZEEQ® (minocycline) compared to topical emollient

时间窗: 5 +/- 1 weeks

Comparison between the efficacy of topical minocycline foam and the control emollient. This will be completed by a dermatologist or dermatology resident that will be blinded to which side was treated with which intervention. Assessment will be completed through a visual analog used by the assessor where REDCap will assign a numeric value based on the position of the marking. The blinded photo reviewer will be informed whether the photo is a baseline or follow-up photo, but will be blinded to which side of the body was treatment or control. The photos will be marked to indicate the side of the body, and the photo reviewer will be asked to compare the left baseline side to the left follow-up side, and similarly the right baseline to the right follow-up, using a visual sliding analogue scale, where REDCap will assign a numeric value based on the position of the marking indicator. Average response to treatment among all patients will be determined.

次要结局

  • Assess possible adverse effects secondary to topical minocycline (AMZEEQ) use(6 +/- 1 weeks)
  • Discern patient satisfaction with daily topical minocycline (AMZEEQ) use compared to daily topical emollient(6 +/- 1 weeks)
