Cancer clinical trials represent the largest single category of recruiting studies worldwide, encompassing everything from early-phase safety studies of novel oncology drugs to large Phase 3 comparisons against current standard-of-care chemotherapy regimens. The field has accelerated dramatically with the rise of immunotherapy, targeted therapies, and CAR-T cell treatments that have transformed outcomes for previously untreatable malignancies.

Trials include checkpoint inhibitors (PD-1/PD-L1 agents), KRAS inhibitors, ADC (antibody-drug conjugates), combination chemotherapy regimens, radiation protocols, and surgical technique comparisons. Many trials stratify by biomarker status (PD-L1 expression, TMB, MSI-H) to identify patients most likely to benefit.

The NCI, pharmaceutical sponsors, and academic cancer centers collectively fund thousands of oncology trials annually across every cancer type.
