Pilot Study Evaluating the Efficacy of a Topical PDE4 Inhibitor for Morphea

Duke University8 enrolled

Overview

This is a pilot study to determine the safety and clinical efficacy of crisaborole 2% ointment in the treatment of morphea.

A Phase 2, pilot, proof-of-concept, open label, single arm prospective study to assess the safety, tolerability and efficacy of using crisaborole 2% ointment for adult morphea. Patients identified by their physician, nurse, or other member of their clinical care team as meeting criteria for the study will be asked to apply crisaborole 2% ointment, twice daily, on affected plaques for 12 weeks. A 4 mm skin punch biopsy will be performed at baseline and at 12 weeks, on the same affected plaque. Dermal thickness will be measured and compared before and at the end of treatment. Patients will have a clinical assessment at baseline and at weeks 4, 8 and 12. After week 12, patients who need further treatment will undergo standard of care treatment as determined by their primary dermatologist. Physician and patient reported assessment and skin imaging will be performed at baseline, week 4, 8 and 12, and at week 20. Photography will also be performed at baseline and week 12. An optional post treatment follow-up will be performed at week 20. Medication will be provided free of charge by Pfizer, as part of the grant that is funding this study. These will be dispensed by the study group at baseline and during the subsequent clinic visits.

Outcomes

Primary Outcomes

Number of Participants Who Had a Reduction in Dermal Thickness of Sentinel Plaque

Change in dermal thickness on skin biopsy. A sentinel plaque will be selected at baseline. A 4 mm skin punch biopsy will be performed at baseline and at 12 weeks, on the same affected plaque.

Time frame: Baseline, 12 weeks

Secondary Outcomes

Percentage of Reduction in DIET Score of Sentinel Plaque

The DIET (Dyspigmentation, Induration, Erythema, and Telangiectasias) score is a physician-assessed, previously validated score. Range is 0-12, and a higher score denotes increased activity or severity.

Time frame: Baseline and 12 weeks

Percentage of Reduction in LoSCAT Score

LoSCAT (Localized Scleroderma Cutaneous Assessment Tool ) score is a physician-assessed, previously validated score. It has 2 components, the LoSSI (localized scleroderma skin severity index, range 0-162), which measures disease activity, and LoSDI (localized scleroderma damage index, range 0-216). The higher the number, the higher the disease activity and damage, respectively.

Time frame: Baseline,12 weeks

Percentage of Reduction in Skindex-29 Score

Skindex-29 is a health-related quality of life score; minimum score 30, maximum 150. Lower score indicates a better quality of life.

Time frame: Baseline and 12 weeks

Change in Dermal Thickness of Sentinel Plaque by Ultrasonography

B-Mode ultrasonographic imaging will be utilized to measure dermal thickness of the sentinel plaque

Time frame: Baseline, 4, 8 and 12 weeks, optional at 20 weeks
