About this trial

The goal of this randomized clinical trial is to learn if topical treatment with ATR04-484 can treat skin rash in patients undergoing EGFR inhibitor (EGFRi) therapy. The primary goal of the study is to determine safety and tolerability of ATR04-484, and the secondary goal of the study is to assess efficacy signals of ATR04-484. Researchers will compare treatment of ATR04-484 to its vehicle. Participants will:

* Apply ATR04-484 or vehicle daily for 28 days * Visit the clinic periodically for evaluation and sample collection

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Adults ≥18 years of age

Has Grade 2 or 3 non-infected moderate to severe EGFRi-related dermal toxicity affecting the face (the neck, chest, back and other areas may also be affected)

Disqualifiers

Significant skin disease other than EGFRi-related dermal toxicity

Treatment with topical mid- to high-potency topical corticosteroids, or topical antibiotics or antibacterial washes on the face, neck, chest, or back within 14 days prior to baseline; treatment with systemic antibiotics or systemic corticosteroids within 14 days prior to baseline

Residing with an immunocompromised person residing with them in the same dwelling from the baseline visit through 2 weeks after the treatment period
