Participants will be enrolled in 2 stages: dose escalation and dose expansion. descriptionModule.briefSummary: This is a first-in-human study to evaluate the safety, tolerability, pharmacokinetics (PK), and anti-tumor activity of enzelkitug when administered as a single agent and in combination with atezolizumab or pembrolizumab in adult participants with locally advanced or metastatic solid tumors, including non small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), melanoma, triple-negative breast cancer (TNBC), esophageal cancer, gastric cancer, cervical cancer, colorectal cancer (CRC), urothelial carcinoma (UC), clear cell renal cell carcinoma (RCC) and hepatocellular carcinoma (HCC).
