Melanoma Drug's hidden effect on moles under microscope
NCT ID NCT06599619
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how a standard immunotherapy drug (anti-PD1) changes the appearance and biology of atypical moles in people with advanced melanoma. Researchers will track 30 patients to see if the drug alters mole size, color, and cellular features. The goal is to better understand how the immune system targets these mole cells during treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Subjects must have at least two atypical nevi of ≥ 4 mm diameter. 2. Subjects must have a current documented history of melanoma. 3. Subject must be ≥ 18 years and if female of childbearing potential, must agree to practice effective contraception per institutional SOC if sexually active. 4. Subjects will have been deemed candidates for adjuvant therapy with single agent anti-PD1 therapy. 5. Subjects must give written informed consent to participate in this study with consent signed and dated prior to entry into trial. Exclusion Criteria: 1. Patients with non-malignant diseases or indications that would preclude the administration of anti-PD1 therapy such as significant immune suppression or active autoimmune disease requiring disease modifying, immunosuppressive therapy, will be ineligible. 2. Patients who have previously received anti-PD1 therapy 3. Patients with history of other active, non-melanoma cancers 4. Patients who are receiving other anti-neoplastic therapy.
