Brief summary

The goal of this clinical trial is to learn about IMM60 with or without pembrolizumab in participants with advanced melanoma or non-small cell lung cancer. There are two phases: * Phase 1: This phase is designed to learn about the safety of IMM60 with or without pembrolizumab and to find a safe dose to test in Phase 2. * Phase 2: This phase is designed to learn whether IMM60 + pembrolizumab improves progression-free survival at 12 months compared to pembrolizumab alone in participants with non-small cell lung cancer.

Detailed description

This exploratory phase 1/phase 2 study is designed to establish a recommended phase 2 dose of IMM60 and provide preliminary estimates of safety and efficacy of IMM60 alone and in combination with pembrolizumab in participants with NSCLC and melanoma. In phase 1, initial safety will be assessed in a multiple dose escalation cohort for IMM60 alone, then for the IMM60 + pembrolizumab combination. Phase 2 of the study will recruit PD-1 pretreated melanoma participants and randomize PD-L1 \> 50% total NSCLC participants 2:1 to IMM60 + pembrolizumab vs pembrolizumab alone. There is an additional cohort of PD-L1 \< 1% NSCLC participants.

Not a woman of childbearing potential (WOCBP) 2. A WOCBP who agrees to follow contraceptive guidance during the treatment period and for at least 6 months after the last dose of study intervention

Exclusion criteria

* Has the following cardiac conditions: 1. Corrected QT interval (QTc) \> 450 ms 2. Uncontrolled hypertension with blood pressure (BP) \> 160/100 despite treatment 3. Class II or greater heart failure as defined by the New York Heart Association 4. Myocardial infarction within 6 months or angina requiring nitrate therapy more than once a week * Another active malignancy within the past 2 years (Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder, or carcinoma in situ \[e.g., breast carcinoma, cervical cancer in situ\] that have undergone potentially curative therapy are not excluded. Also, prostate, breast, and neuroendocrine tumors that are stable on hormonal treatment for a period of 1 year or more without the need to adjust dose are not excluded.) * Has had an allogeneic tissue/solid organ transplant * Known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable. * History of (non-infectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease * Participants with an active autoimmune disease or a documented history of autoimmune disease or syndrome that requires systemic steroids (in dosing exceeding 10 mg daily of prednisone equivalent) or immunosuppressive agents. * Participants who are known to be serologically positive for Hepatitis B, Hepatitis C, or human immunodeficiency virus.
