Quickly find the trials you need across 500,000+ studies
Clinical trials are research studies that test how well new medical approaches work in people. Every new drug, treatment, or medical device must go through clinical trials before it can be approved for general use. Our database aggregates trials from registries worldwide, giving you a complete picture of what's being studied, by whom, and where.
Search
The search bar is the simplest way to explore clinical trials. Type what you're looking for: a disease name, a drug, a sponsor, or even an NCT number if you have one. The NCT number (National Clinical Trial number) is a unique identifier assigned to each study registered on ClinicalTrials.gov — if you know it, you can go directly to that trial.
Example searches:
You can combine multiple terms in a single search. For instance, "lung cancer immunotherapy phase 3" will find Phase 3 immunotherapy trials for lung cancer.
Results appear instantly as you type. Our search engine understands synonyms and medical terminology, so searching for "heart attack" will also find trials about "myocardial infarction". From your results, you can refine them using the filters on the left, or click on any trial to see its full details.
Search
Depending on your needs, you can switch between two modes using the toggle at the top right of the search bar. Each mode is optimized for different use cases.
Recommended for getting started
A single search bar, just like Google. Type what you're looking for and results appear. The search engine handles the complexity for you, looking across trial titles, descriptions, conditions, treatments, and sponsors.
Best for: Finding a specific trial, exploring a disease area, seeing what a sponsor is working on, getting a quick overview.
For complex searches
Build precise queries by combining multiple criteria: phase, status, enrollment size, dates, specific countries, and more. Each criterion can be set independently for maximum control.
Best for: Competitive intelligence, market research, finding investigation sites, building targeted trial lists, regulatory analysis.
You can switch between modes at any time without losing your search. Expert mode simply shows more filter options upfront, while Simple mode keeps them tucked away in the sidebar until you need them.
Search
Clinical trials progress through distinct phases, each with a specific purpose. Understanding these phases helps you interpret where a treatment is in its development journey and what kind of data might be available.
The first tests in humans, typically involving 20-100 healthy volunteers or patients. The main goal is to evaluate safety, determine safe dosage ranges, and identify side effects. About 70% of drugs move from Phase 1 to Phase 2.
Duration: Several months
Tests whether the treatment actually works for the intended condition. Involves 100-300 patients who have the disease or condition. Researchers look for preliminary evidence of effectiveness while continuing to monitor safety. About 33% of drugs move to Phase 3.
Duration: Several months to 2 years
Large-scale studies involving 300-3,000+ patients to confirm effectiveness, monitor side effects, compare to existing treatments, and collect information for safe use. These are the pivotal trials needed for regulatory approval. About 25-30% of drugs complete Phase 3.
Duration: 1-4 years
Studies conducted after the treatment is already approved and on the market. These track long-term effects, explore use in different populations, and may investigate new indications. Also called "post-marketing studies".
Duration: Ongoing
Combined phases
You'll sometimes see "Phase 1/2" or "Phase 2/3" trials. These combine objectives from both phases in a single study to accelerate development. This is common in oncology and rare diseases where patient populations are limited.
Search
The recruitment status tells you where a trial stands in its lifecycle. This is crucial information whether you're looking for trials to join, tracking a competitor, or analyzing market activity.
The trial is actively seeking participants. If you're looking to enroll patients or find sites, these are the trials to focus on.
The trial is ongoing but has stopped enrolling new participants. Patients already enrolled are still being treated and followed.
The trial is registered and approved but hasn't started enrolling yet. Useful for tracking upcoming competitive activity.
The trial has finished — all participants have completed the study. Results may or may not be posted yet.
Temporarily paused, often for safety reviews, protocol changes, or administrative reasons. May resume later.
Stopped early and will not resume. This can happen for safety concerns, lack of efficacy, business decisions, or enrollment difficulties.
The trial was registered but never started — no participants were ever enrolled. Often due to funding issues or strategic changes.
The trial is selecting participants from a specific population and is not open to the general public.
These statuses are updated by trial sponsors as required by regulatory authorities. Updates typically happen within 30 days of any status change.
Search
Once you have initial results, use the filters in the sidebar to narrow them down. Each filter you add reduces results to only trials matching all your criteria. Filters are cumulative — adding more filters gives you more specific results.
Filter by the current state of the trial. Select one or more statuses to include. For example, select both "Recruiting" and "Not yet recruiting" to see all active and upcoming trials.
Focus on a specific stage of clinical development. This is particularly useful for competitive intelligence — Phase 3 trials represent drugs closest to market approval.
Start typing and select from the suggestions. Our autocomplete understands synonyms and alternate names — for example, typing "Pfizer" will also suggest "Wyeth" (acquired by Pfizer) and related entities.
You can select multiple values for each filter. For example, selecting both "United States" and "Germany" will show trials running in either country.
Find trials based on the target number of participants. Enrollment size often indicates the type and purpose of a study:
Filter by the nature of the research:
Filter by start date or expected completion date. This helps you focus on recent activity or look ahead at upcoming trial completions.
Quick presets are available: "Started this year", "Completing this year", "Since 2020", and more. You can also set custom date ranges.
Turn this on to only see trials that have posted their results to the registry. By regulation, most trials must post results within 12 months of completion, but compliance varies. This filter helps you find trials with actual outcome data.
Search
Four display modes are available, each optimized for different tasks. Click the icons at the top of the results to switch between them.
Dense view, one line per trial. Shows NCT ID, title, status, and phase at a glance.
