(a) NSCLC, (b) cutaneous melanoma, (c) HNSCC, (d) UC, or (e) TNBC, which are refractory to or otherwise ineligible for treatment with standard-of-care treatments

Prior therapy in each disease setting must include the following:

NSCLC: Patients must have experienced disease progression following platinum-containing chemotherapy and a PD-1 or PD-L1 inhibitor. Patients with EGFR, ALK, ROS-1, or other actionable mutations should have previously received or been ineligible for therapies targeting their respective mutation(s).
Cutaneous melanoma: Patients must have experienced disease progression following a PD-1 or PD-L1 inhibitor. Patients with V600E mutations should have previously received or been ineligible for approved BRAF inhibitor or MEK inhibitor therapy.
HNSCC: Patients must have experienced disease progression following platinum-based combination chemotherapy and a PD-1 or PD-L1 inhibitor.
UC: Patients must have experienced disease progression following platinum-based combination chemotherapy and a PD-1 or PD-L1 inhibitor.
TNBC: Patients must have experienced disease progression following single-agent or combination chemotherapy. Patients with BRCA1/2 mutations should have previously received or been ineligible for an approved PARP inhibitor; patients who are PD-L1 positive should have received or been ineligible for an approved PD-1 or PD-L1 inhibitor.
Disease must be measurable per Response Evaluation Criteria
The shorter of 28 days or 5 half-lives must have elapsed since the completion of prior therapy, before initiation of study treatment.
