Objective:
Part 1 Primary Objective:
- Determination of the MTD and/or MRD of MCLA-128.
Secondary Objectives:
- To characterize the safety and tolerability of MCLA-128.
- PK profile of MCLA-128.
- Immunogenicity of MCLA-128.
- Evaluation of anti-tumor response and clinical benefit rate (CBR).
Part 2 Primary Safety Objective:
- To characterize the safety and tolerability of MCLA-128.
Primary Efficacy Objectives:
- To explore the relationships between the anti-tumor activity of MCLA-128 and disease-related biomarkers
- To assess magnitude of anti-tumor activity of MCLA-128 in patients with NRG1 fusion (Cohorts F, G, H)
Key Secondary Objective:
- To assess durability of anti-tumor activity of MCLA-128 in patients with NRG1 fusions (Cohorts F, G, H)
Secondary Objectives:
- PK profile of MCLA-128.
- Immunogenicity of MCLA-128.
- Evaluation of PFS and overall survival, duration of response
