To Compare the Efficacy of Weekly Azathioprine Pulse Versus Betamethasone Oral Mini-Pulse in the Treatment of Moderate to Severe Alopecia Areata

Phase 2

Completed

• Conditions: Alopecia Areata; Alopecia Areata(AA)
• Interventions: Drug: Azathioprine (AZA); Drug: Betamethasone

• Registration Number: NCT06786689
• Lead Sponsor: Sheikh Zayed Medical College

Brief Summary

Alopecia areata (AA) is an autoimmune condition characterized by non-scarring hair loss, ranging from minor patches to complete baldness. Given the variable effectiveness of existing treatments, this study aimed to compare the efficacy of weekly Azathioprine pulse (WAP) therapy against Betamethasone oral mini-pulse (BOMP) therapy in managing moderate to severe AA.

Detailed Description

Alopecia areata (AA) is an autoimmune disorder characterized by non-scarring, solitary, or multiple circular or oval patches of hair loss on scalp or other hear bearing areas. These patches often feature "exclamation mark hairs" near their leading edges. It effects all demographics irrespective of age, sex, and ethnicity. Clinically, Alopecia areata can be categorized in various forms depending on extent of involvement, such as patchy hair loss on the scalp, Alopecia Totalis (complete scalp hair loss), or Alopecia Universalis (complete scalp and body hair loss), or less commonly, as band-like hair loss on specific regions of the scalp.

Given the uncertain pathogenesis and course of the disease, the effectiveness of treatment modalities remains unpredictable. Effective treatment must address both the clinical efficacy and safety. Previous studies have reported variable safety profiles, remission, and relapse rates for weekly Azathioprine pulse therapy versus Betamethasone oral mini-pulse therapy, particularly when compared to placebo. However, direct comparisons, especially within our local demographic, are notably lacking. Therefore, this study aimed to bridge the existing gap in literature by offering a comparative evaluation of these therapies in the management of moderate to severe alopecia areata.

Arm && Interventions

Group	Intervention	Description
Weekly Azathioprine Pulse Therapy (Group A)	Azathioprine (AZA)	single dose of Tab. Azathioprine 300 mg once weekly
Betamethasone Oral Mini Pulse (Group B)	Betamethasone	Tab. Betamethasone 5mg for 2 consecutive days weekly for 3 months

Primary Outcome Measures

Name	Time	Method
Severity of Alopecia Tool (SALT) score	Clinical Assessment will be done monthly for 6 months	photographs of the standard four views of the scalp were captured at initial and follow-up appointments using a 50-megapixel Mobile camera under consistent lighting conditions. The Severity of Alopecia Tool (SALT) score was determined by dividing the scalp into four sections according to their surface areas: the top at 40%, the back at 24%, and each side (left and right) at 18%. The SALT score calculation involved the sum of the percentage of hair loss from the left side (0.18) plus the right side (0.18), the vertex (0.40), and the back (0.24). SALT scores were evaluated at baseline, 12 weeks post-treatment initiation, and 3 months after completion of treatment. Treatment response was determined by using the formula: Percentage of hair regrowth= (SALT score at baseline - SALT score at follow-up) x100 / SALT score at baseline. Treatment response was further divided into 4 categories: Poor response (\<25% hair growth improvement from baseline), Moderate response (26-50% improvement), Goo
