This trial is being done to see if an experimental drug (SEA-CD40) works when it's given with other cancer drugs to treat some types of cancer. It will also study side effects from the drug.

There are 2 parts in this trial. In one part, participants have melanoma that has come back after treatment or can't be removed by surgery. Participants in this part will get SEA-CD40 and pembrolizumab. In the other part, participants have non-small cell lung cancer (NSCLC) that has spread through their body. These participants will get SEA-CD40, pembrolizumab, carboplatin, and pemetrexed.

An Open-label, Phase 2 Basket Study of SEA-CD40 Combination Therapies in Advanced Malignancies

Open to people ages 18 years and up

  • Histologically or cytologically confirmed unresectable malignancy defined as one of the following:
    • 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.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0 or 1
  • Measurable disease per RECIST v1.1 at baseline

You CAN'T join if...

  • History of another malignancy within 3 years of first dose of study drug
  • Active central nervous system (CNS) metastases and/or carcinomatous meningitis.
  • Previous exposure to CD40-targeted therapy
  • Currently on chronic systemic steroids in excess of physiologic replacement
  • Has had an allogeneic tissue/solid organ transplant.
  • History of autoimmune disease that has required systemic treatment in the past 2 years
