It lists publicly and privately funded studies in the U.S. and around the world.\n\n## What they offer\n\n- Search by condition (for example \"ALK-positive lung cancer\"), drug, biomarker, location and recruiting status.\n- A page for each study with its design, eligibility criteria, locations and contacts.\n- Results for many completed studies.\n\n## How it works and what it costs\n\nIt's free and needs no account. Expect dense language; eligibility lists are long and written for doctors. Save the study's NCT number and bring it to your oncologist, or ask a navigator to help you read it.\n\n## How it fits with other services here\n\nMatching services such as Massive Bio do the search for you. [LUNGevity](/companies/lungevity/) and [GO2 for Lung Cancer](/companies/go2-for-lung-cancer/) have lung cancer trial navigators. My [clinical trials guide](/resources/clinical-trials/) covers what to ask about any study.\n\n## Questions I would ask\n\n- Is this study still enrolling at the site closest to me?\n- Do my biomarker and prior treatments meet the inclusion criteria?\n- What would I need to do, and how often would I travel?\n- Who covers the costs of the study drug, tests and travel?\n\n## Contacts\n\n- Website: [clinicaltrials.gov](https://clinicaltrials.gov/)","topics":["clinical-trials"],"capabilities":["clinical-trials"],"organizationType":"academic-center","services":["trial-navigation"],"communityFocus":["Anyone looking for clinical trials"],"sources":[{"id":"home","label":"ClinicalTrials.gov","url":"https://clinicaltrials.gov/","publisher":"U.S. National Library of Medicine","checkedAt":"2026-10-23","supports":"Official registry of clinical studies run by the U.S. National Library of Medicine; publicly and privately funded studies in the U.S. and worldwide; search by condition, intervention and location; study records with eligibility, locations and contacts; free public access.","type":"official"}],"applicability":"For patients and caregivers who want help finding clinical trials to discuss with their oncologist.
