  • Cohort 1: Relapsed and/or refractory metastatic melanoma
  • Uveal/ocular melanoma is excluded
  • Must have progressed on treatment with an anti-PD-(L)1 mAb. PD-(L)1 treatment progression is defined as meeting all of the following criteria:
  • Has received at least 2 doses of an approved anti-PD-(L)1 mAb
  • Has demonstrated disease progression after PD-(L)1 as defined by RECIST v1.1.
  • Progressive disease has been documented within 12 weeks from the last dose of anti- PD-(L)1 mAb
  • Last dose of anti-PD-(L)1 must have been within 90 days prior to enrollment
  • Participants with a targetable BRAF mutation must have been treated with, been intolerant of, or declined treatment with BRAF/MEK targeted therapy prior to study entry
  • Cohort 2: Metastatic uveal melanoma
  • Must not have received prior treatment for advanced or metastatic disease except for prior adjuvant/neoadjuvant immunotherapy
  • No prior liver-directed therapy
  • Cohort 3: Metastatic PD-(L)1-naive melanoma
  • Uveal/ocular melanoma is excluded
  • Must not have received prior treatment for advanced or metastatic disease except for prior adjuvant/neoadjuvant immunotherapy.
  • For participants with a targetable BRAF mutation, prior BRAF/MEK targeted therapy is allowed if completed 4 weeks prior to first dose of study treatment.
  • Cohorts 4 and 5: Non-squamous NSCLC
  • Participants must have stage IV disease per AJCC 8th edition
  • No known driver mutations/alterations mutation for which targeted therapy is available
  • Must have non-squamous histology.
  • No prior therapy for metastatic disease
  • No prior treatment with anti-PD-(L)1 or PD-L2 agent or an antibody targeting other immuno-regulatory receptors or mechanisms
• Able to provide archival tumor tissue from locations not radiated prior to biopsy. If archival tumor sample is not available a fresh baseline biopsy is required.
