Trial Outcomes & Findings for Comparison of Efficacy of Methotrexate and Azathioprine in Patients With Chronic Actinic Dermatitis: A Randomized Controlled Trial (NCT NCT06476366)

NCT ID: NCT06476366

Last Updated: 2025-08-17

Results Overview

EASI-50 means 50% reduction in the Eczema Area and Severity Index score from baseline score. EASI is a scale used to evaluate the degree and severity of eczema. The total EASI score is between 0 and 72 . Mild disease: Patients with a score of 1.1-7.0 on the EASI scale will be classified as having mild disease. Moderate disease: Patients with a score of 7.1 to 21.0 on the EASI scale will be classified as having moderate disease. Severe disease: Patients with a score of 21.1-50.0 on the EASI scale will be classified as having severe disease. Very Severe disease: Patients with a score of 50.1-72.0 on the EASI scale will be classified as having very severe disease.

Participant Flow

10 patients recruited in each arm after informed consent as detailed in the attached document

Group A was administered oral methotrexate 10mg/week after a test dose while group B was administered tablet azathioprine at a dose of 0.3mg/kg daily after testing for TPMT levels. Both group of patients were advised regarding strict sun protection measures (sunblock, hats, sunglasses). The baseline investigations for both groups included complete blood picture (CBC), liver function tests (LFTs), renal function tests (RFTs), electrocardiogram, chest X-ray and urine analysis

Measure
Methotrexate Arm
After the enrollment of patients and taking consent, participants will be divided in two treatment groups via lottery method. Group A will be administered oral methotrexate 10mg/week after a test dose
Azathioprine
group B will be administered tablet azathioprine at a dose of 0.3mg/kg daily after. Both group of patients will be advised regarding strict sun protection measures (sunblock, hats, sunglasses etc.). The baseline investigations for both groups will include complete blood picture (CBC), liver function tests (LFTs), renal function tests (RFTs), electrocardiogram, chest X-ray and urine analysis while thiopurine methyltransferase (TPMT) levels will be assessed specifically for group B patients. The patients will be followed up at week 4, 12 and 24. CBC, RFTs and LFTs will be done at each follow-up and EASI score will be calculated,

Baseline Characteristics

Out of a total of 20 patients recruited, 4 were lost to follow-up (three from AZT arm and one from MTX arm). One patient developed anemia while on methotrexate and the treatment was discontinued. The final analysis included a total of 15 patients (7 from AZT arm and 8 from MTX arm).

SECONDARY outcome

Timeframe: 6 months

Investigator global assessment (IGA) is a subjective measure of disease severity which is assessed by the physician on patient's visit. It ranges from 0 to 4 (0-clear, 1-almost clear, 2-mild, 3-moderate, 4-severe)
