Topical Composition Therapy for the Treatment of Cutaneous Mastocytosis

A Phase 2 interventional study of Topical preparation of sodium cromolyn 5%, diphenhydramine 1% and trolamine salicylate 10% in emollient cream base. in Cutaneous Mastocytoses, sponsored by Joseph Butterfield. Terminated at 1 site in United States. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2024-04-25.

Sponsored by Joseph Butterfield · Phase 2, Interventional, and Treatment

Why this study was terminated
It was difficult to enroll patients during the pandemic. A new oral drug, Avapritinib, has since been approved for systemic mastocytosis. This medication controls skin manifestations of mastocytosis and is more convenient for patients to use.

What researchers measure

Primary outcomes

  1. Cutaneous Symptom Relief

    Number of participants who achieve complete resolution or near-complete clearing of cutaneous symptoms of treated, involved skin

    Time frame: 2 weeks

  2. SkinDex-16 Quality of Life Questionnaire

    This validated questionnaire is a 16-item, participant-reported survey used to assess quality of life impacts due to the participant's skin condition. Scores range from 0 to 6, where 0 is never bothered by the skin condition and 6 is always bothered by the skin condition. Results are summed to produce an overall score, ranging from 0 to 96, where lower scores indicated a higher level of quality of life.
