● UNDERSTANDING CLINICAL TRIALS
A clinical trial is a research study conducted in people to evaluate a medical intervention — a drug, device, procedure, or behavioral change. All trials are registered on ClinicalTrials.gov before enrollment begins, as required by U.S. law (FDAAA 801). Trials are classified by phase: Phase 1 tests safety in small groups, Phase 2 tests efficacy, Phase 3 compares to existing treatments in large populations, and Phase 4 monitors long-term effects after approval.
Read full guide →Every trial defines inclusion and exclusion criteria — the specific requirements a participant must meet. Common factors include age range, diagnosis, disease stage, prior treatments, and current medications. Eligibility criteria exist to protect patient safety and ensure valid scientific results. You can review the full criteria for any trial on its ClinicalTrials.gov registry page before contacting the study team.
Read eligibility guide →Compensation varies widely by trial type, duration, and sponsor. Phase 1 trials (healthy volunteers) often pay $1,000–$5,000 for inpatient stays. Later-phase trials for patients with specific conditions typically reimburse travel and time costs rather than paying a flat fee. FDA guidance requires that payment not be so high as to be coercive. Always review the informed consent document for specific payment terms before enrolling.

What Are Clinical Trials?
Clinical trials are carefully designed research studies that evaluate new medical treatments, drugs, devices, or behavioral interventions in human volunteers who meet defined eligibility criteria. These studies follow a strict scientific protocol approved by an independent ethics board before any recruiting of participants begins.
Live recruiting studies listed on ClinicalTrials.gov represent the most current opportunities for patients and healthy volunteers to participate in cutting-edge medical research across hundreds of conditions worldwide. ClinicalMetric organizes these studies so researchers, patients, and healthcare professionals can find relevant trials quickly.
How to Find the Right Trial
Finding the right clinical trial begins with identifying your condition, location preferences, and the phase of research you are comfortable joining. Earlier phases carry more uncertainty while later phases involve well-characterized interventions already studied in many participants.
Each trial listing includes eligibility criteria specifying the required age range, diagnosis, prior treatment history, and any exclusion factors. Reviewing these details carefully before contacting the study team saves time for everyone involved in the screening process.
Understanding Trial Phases
Clinical trials progress through four standardized phases. Phase 1 studies enroll 20–80 participants primarily to evaluate safety and dosing. Phase 2 expands to 100–300 participants and tests therapeutic effect. Phase 3 compares the new intervention against standard-of-care treatments across thousands of participants. Phase 4 studies occur after regulatory approval and monitor long-term safety in the general population.
