A Study to Evaluate of the Efficacy and Safety of Imsidolimab (ANB019) in the Treatment of Acneiform Rash

A Phase 2a, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of ANB019 in the Treatment of Acneiform Rash in Subjects With Neoplasm Receiving EGFRi or MEKi Therapy

Efficacy and Safety of imsidolimab in participants with epidermal growth factor receptor inhibitor (EGFRi)/mitogen-activated protein (MAP)/extracellular signal-regulated kinase (ERK) kinase inhibitor (MEKi)-associated acneiform Rash

This study is a Phase 2a, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy, safety, and tolerability of imsidolimab compared with placebo in cancer participants with EGFRi/MEKi-associated acneiform rash. This study will also characterize the pharmacokinetic (PK) profile of imsidolimab and explore the immune response to imsidolimab in participants with EGFRi/MEKi-associated acneiform rash.

Inclusion Criteria:

• Participant has cancer
• Participant is treated with an oral or injectable Food and Drug Administration (FDA)-approved EGFRi or MEKi therapy
• Participant has EGFRi/MEKi-related acneiform rash of Grade ≥ 2 as per common terminology criteria for adverse events (CTCAE) version 5.0, and ≥ 20 inflammatory lesions on the face at screening and Day 1.

Exclusion Criteria:

• Participant has infected EGFRi/MEKi-associated acneiform rash according to investigator's evaluation.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
