A Trial of a Botanical Drug Product Containing East Indian Sandalwood Oil (EISO) For Treatment of Atopic Dermatitis

Phase 2

Withdrawn

• Conditions: Atopic Dermatitis
• Interventions: Drug: Placebo; Drug: SAN007 Cream

• Registration Number: NCT03000595
• Lead Sponsor: Santalis Pharmaceuticals, Inc.

Brief Summary

This trial will be a double-blind, randomized, placebo-controlled, safety, tolerability and efficacy trial of SAN007 (5% East Indian sandalwood oil in a cream formulation) treatment regimen when administered daily for up to 28 days to patients from 3 months to 65 years of age, with atopic dermatitis.

Detailed Description

Patients will enter the Screening Period once the informed consent/ascent and photographic consent process has been completed. Patients with a total body surface area (BSA) of ≥2% and ≤ 15% atopic dermatitis involvement, in the treatable areas, and who meet all of the inclusion and none of the exclusion criteria will be enrolled.

Once patient eligibility is confirmed and the screening procedures completed, the patient will start the Treatment Period of the study. All enrolled patients will receive either 5% SAN007 cream or placebo cream (randomized in a 2:1 ratio) with the first dose applied at the Day 1 Study Visit. Patients and/or their legally authorized representative will be instructed on how to apply the study medication twice daily for 28 days. Patients will return to the clinic on Study Days 7,14 and 28 for study-related assessments. Patients and/or their LAR will receive a telephone contact from the site, on Study Days 21 and 35.

Safety will be assessed by evaluating adverse events (AEs) with respect to severity, duration, and relationship to study drug.

In addition cutaneous tolerability will be evaluated at each visit. Tolerability evaluation will be based on patients reporting discomfort during or immediately following application of SAN007. This will also be recorded as an AE. The study exclusion areas are to be not to be used in this evaluation.

Efficacy will be assessed at each study visit through the completion of the IGA, EASI and BSA calculation.

During the active treatment period, Patients will return to the study site according to the study schedule for interim assessments and recording of concomitant medication and adverse events (AEs).
