Are cancer clinical trials free?

The experimental drug, study-related tests, and research-team time are typically paid for by the trial sponsor. Routine care given during the trial (standard imaging, hospital stays, clinic visits) is billed to your insurance as usual. Most patients have little or no out-of-pocket cost beyond what they'd pay for standard treatment.

Federal law (and California law) requires most insurance plans, including Medicare, to cover the routine patient-care costs of qualifying clinical trials.

Sponsors usually cover: the investigational drug, extra labs and scans required only for the study, and any travel-stipend programs offered by the trial.

Always ask the trial coordinator for a written breakdown of what's covered by the sponsor vs. what's billed to insurance.
