What if I can’t find a clinical trial that’s right for me on this website?
Our Find a Trial search engine only provides information about Pfizer clinical trials. To search for all registered clinical trials, regardless of the study sponsor, you may visit ClinicalTrials.gov.
Why can’t I find a clinical trial listing that I previously saw on this website?
Once a clinical trial has finished recruitment, the trial listing is typically removed from our Find a Trial search engine. Studies that have completed enrollment can still be found on ClinicalTrials.gov.
