Pilot Study of the Safety and Efficacy of Apremilast in Subjects With Moderate to Severe Alopecia Areata

A Randomized Placebo-controlled Single Center Pilot Study of the Safety and Efficacy of Apremilast in Subjects With Moderate to Severe Alopecia Areata

Alopecia areata (AA) is a medical condition, in which the hair falls out in patches. The hair can fall out on the scalp or elsewhere on the face and body.

Alopecia areata is an autoimmune skin disease, which means that the immune system is recognizing the hair follicles as foreign and attacking them, causing round patches of hair loss. It can progress to total scalp hair loss (alopecia totalis) or complete body hair loss (alopecia universalis). The scalp is the most commonly affected area, but the beard or any hair-bearing site can be affected alone or together with the scalp. Alopecia areata occurs in males and females of all ages, and is a highly unpredictable condition that tends to recur. Alopecia areata can cause significant distress to both patients and their families.

In this study, the aim to assess the effects of a new treatment called apremilast in patients with alopecia areata. A total of 30 patients will be included in the study, which will run for a total of 52 weeks.

Study Overview

• Status: Completed
• Conditions: Alopecia Areata
• Intervention / Treatment: Drug: Placebo; Drug: Apremilast

Detailed Description

This is a randomized, double-blind, placebo-controlled pilot study consisting of two phases. A total of 30 subjects with moderate to severe alopecia areata (including universalis and totalis) involving 50-100% of the scalp will be enrolled. A possible maximum of 15 patients (approximately 7 patients each) with current episodes of AA totalis / universalis may be included in this study.

In Phase 1, subjects will be randomized (2:1) to either receive apremilast or placebo for 24 weeks.

In Phase 2, eligible subjects will receive apremilast from Week 24 through Week 48. The following subjects will be eligible to enter into Phase 2:

1. Subjects who received placebo in Phase 1 of the study
2. Subjects who received apremilast in Phase 1 of the study, and who achieved a minimum of 50% regrowth (SALT50) at Week 24, compared to Baseline.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Patients With SALT50	Number of patients achieving 50% or greater improvement in their Severity of Alopecia Tool (SALT) score (SALT50) at Week 24 SALT50 is defined as the percent of patients achieving >=50% reduction in SALT score compared to baseline. Scalp is divided into 4 areas namely, Vertex - 40% (0.4) of scalp surface area; right profile of scalp - 18% (0.18) of scalp surface area; left profile of scalp - 18% (0.18) of scalp surface area; Posterior aspect of scalp - 24% (0.24) of scalp surface area. Percentage of hair loss in any of these areas is percentage hair loss multiplied by percent surface area of the scalp in that area. SALT score is the sum of percentage of hair loss in all above mentioned areas.	Baseline and Week 24

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Change in SALT Score	Mean percent change in SALT score at 4, 8, 12, 16, 20, and 24 weeks as compared to baseline	Baseline and week 4, 8, 12, 16, 20, 24
Phase 2: Number of Patients Achieving aaPGA Score of 3 or Above	Number of subjects achieving an alopecia areata Physician's Global Assessment (aaPGA) score of 3 or above at Weeks 24 (0, no regrowth; 1, <25% of regrowth; 2, 25%-49% of regrowth; 3, 50%-74% of regrowth; 4, 75%-99% of re- growth; 5, 100% of regrowth).	Week 24 and Week 48
Phase 2: Change in AASIS	Change from Baseline in the Alopecia Areata Symptom Impact Scale (AASIS) at Weeks 24 and Week 48 The AASIS is a 13-items disease-specific patient-reported outcomes measure that asks participants about symptoms related to alopecia areata and how these symptoms interfere with daily functioning. Total scale ranges from 0-130, with higher score indicating more symptoms.	Week 24 and Weeks 48
Phase 2: AA-QoL	Change from baseline in the Alopecia Areata Quality of Life questionnaire (AA-QoL) at Weeks 24 and Weeks 48. Total scale from 0 to 100, with higher score indicating better quality of life.	Baseline, Week 24 and Weeks 48
Phase 2: Semiquantitative Score	Semiquantitative score using SALT subclasses (0, no hair loss; 1, <25% hair loss; 2, 25%-49% hair loss; 3, 50%-74% hair loss; 4, 75%-99% hair loss; 5, 100% hair loss) at week 24 and week 48 compared to baseline	Baseline, Week 24 and Weeks 48
