How to Find Clinical Trials for Your Condition
A step-by-step guide to searching for, evaluating, and enrolling in clinical trials that match your condition and location.
Where to Start Your Search
Finding the right clinical trial can feel overwhelming, but it does not have to be. The largest public database of clinical trials is ClinicalTrials.gov, maintained by the U.S. National Library of Medicine, which contains over 500,000 studies from around the world. However, the listings on ClinicalTrials.gov use clinical jargon and complex medical terminology that can be difficult for patients to understand. That is exactly why TrialFinder exists — we pull recruiting trial data from ClinicalTrials.gov and translate the eligibility criteria into plain English. Start your search on TrialFinder by entering your condition name. You will see a list of recruiting trials along with their phases, sponsors, locations, and eligibility criteria explained in language you can understand. You can also search by sponsor, by state, or by trial phase. Other resources include the National Cancer Institute's cancer trial search, disease-specific foundations (such as the American Heart Association or the Alzheimer's Association), and patient advocacy organizations that maintain condition-specific trial databases.
Understanding What You See in a Trial Listing
Each clinical trial listing contains several key pieces of information that help you determine whether it might be right for you. The title describes what is being studied. The phase tells you how far along the treatment is in the testing process — Phase 1 focuses on safety, Phase 2 on effectiveness, Phase 3 on large-scale confirmation, and Phase 4 on post-approval monitoring. The status indicates whether the trial is currently recruiting participants. The sponsor identifies who is funding and running the study — this could be a pharmaceutical company, a government agency like the NIH, or a university. The eligibility criteria describe who can and cannot participate, including age ranges, required diagnoses, permitted and excluded medications, and health requirements. The study design section describes whether the trial is randomized, blinded, or placebo-controlled. Location information tells you where the trial sites are and whether remote participation is possible. The estimated enrollment tells you how many participants the trial plans to include, and the estimated completion date gives you a sense of how long the study will run.
Reading Eligibility Criteria
Eligibility criteria are the most important factor in determining whether you can participate in a trial, and they are often the most confusing part of the listing. Inclusion criteria describe what you must have — such as a specific diagnosis, age range, prior treatment history, or lab values. Exclusion criteria describe what would prevent you from participating — such as certain co-existing conditions, medications you are currently taking, or recent surgeries. Do not rule yourself out based on eligibility criteria alone. The criteria listed on ClinicalTrials.gov represent the formal protocol requirements, but in practice, the research team may have some flexibility, particularly for criteria related to lab values or timing. If you think you might qualify but are not sure, contact the trial site directly — they can do a preliminary screening to assess your eligibility. On TrialFinder, we translate the clinical language of eligibility criteria into plain English to make this process easier. Instead of "ECOG performance status 0-1," we explain what that means for your daily functioning. Instead of listing excluded medications by their generic chemical names, we provide the brand names you are more likely to recognize.
Filtering by Phase, Location, and Sponsor
Narrowing your search helps you find the most relevant trials quickly. Filtering by phase allows you to focus on the stage that matches your goals — if you want access to treatments closest to approval, look at Phase 3 trials; if you want the most innovative early-stage therapies, look at Phase 1 and Phase 2. Filtering by location is essential for practical reasons — you will need to travel to the trial site for visits, sometimes frequently, so proximity matters. Many trials are conducted at multiple sites across the country, and some are beginning to offer decentralized or hybrid models with remote visits. Filtering by sponsor can be useful if you want to participate in a trial run by a specific institution or company. Industry-sponsored trials (run by pharmaceutical companies) often have more resources and may cover more participant costs, while academic or government-sponsored trials may focus on conditions with less commercial interest. TrialFinder allows you to browse by condition, phase, sponsor, sponsor type, and state, making it easy to find trials that match your specific situation and location.
Talking to Your Doctor About Trials
Your doctor is the most important partner in your search for a clinical trial. They understand your complete medical history, current medications, and overall health status in a way that no database can capture. Once you have identified trials that interest you, bring the information to your doctor and ask for their assessment. Key questions to discuss include: Based on my medical history, do I likely meet the eligibility criteria? How does this trial compare to my current treatment plan? What are the potential risks specific to my situation? Would participating in this trial be logistically feasible given my health and life circumstances? Some doctors may proactively suggest clinical trials, especially at academic medical centers where trials are actively recruiting. Others may be less familiar with available trials — in that case, you can bring trial listings from TrialFinder or ClinicalTrials.gov to the conversation. Your doctor can also contact the trial's principal investigator directly to discuss your case and determine whether you would be a good candidate. If your doctor is not supportive of clinical trial participation but you believe it could be beneficial, consider seeking a second opinion from a specialist at a center that conducts research in your condition.
Contacting the Research Team
Once you and your doctor have identified a trial that looks promising, the next step is contacting the research team at the trial site. Each trial listing includes contact information — usually a clinical research coordinator or the principal investigator's office. When you reach out, be prepared to provide basic information about your diagnosis, treatment history, and current medications. The research team will typically conduct a preliminary phone screening to determine whether you might be eligible before scheduling an in-person visit. This is not a commitment — you are simply starting a conversation. During the screening process, the team will review your medical records, conduct any required tests, and walk you through the informed consent document. If you meet all of the eligibility criteria and decide to enroll, the consent process formally begins. Throughout this process, you should feel comfortable asking questions and taking the time you need to make your decision. Reputable research teams welcome questions and understand that patients need time to consider their options. If you feel pressured to enroll quickly, that is a red flag — ethical clinical research never pressures patients into participating.
Understanding Your Rights as a Participant
Federal regulations and international ethical standards provide robust protections for clinical trial participants. You have the right to receive complete information about the trial before deciding to participate. You have the right to ask questions at any time during the study and receive honest answers. You have the right to withdraw from the trial at any time, for any reason, without penalty or impact on your standard medical care. You have the right to privacy — your personal health information is protected by HIPAA and research-specific confidentiality protections. You have the right to know about any new findings during the trial that might affect your willingness to continue participating. The Institutional Review Board (IRB) that approved the trial provides ongoing oversight to ensure your rights are protected. If you ever feel that your rights are being violated or that safety protocols are not being followed, you can report your concerns to the IRB, which is required to investigate. The Data Safety Monitoring Board (DSMB) independently monitors the trial's safety data and can halt the study if safety concerns arise. These protections exist because the safety and well-being of participants is the highest priority in clinical research — always above the scientific objectives of the study.
Practical Tips for Your Trial Search
Here are practical steps to make your clinical trial search more effective. First, learn the medical name for your specific condition — trials use precise diagnostic terms, and searching with the right terminology yields better results. Second, keep a summary of your medical history readily available, including your diagnosis, stage, prior treatments, current medications, and key lab values — this information is needed for every eligibility screening. Third, search broadly at first, then narrow down — you may find relevant trials under related condition names or different treatment approaches. Fourth, check back regularly — new trials open frequently, and a trial that was not recruiting last month may be recruiting now. Fifth, consider geographic flexibility — if you are willing to travel, you will have access to more trials. Some trials cover travel expenses, and nonprofit organizations like the Patient Access Network Foundation and the HealthWell Foundation may offer financial assistance. Sixth, join patient communities and advocacy organizations for your condition — they often share information about new trials and can connect you with others who have participated. Finally, remember that TrialFinder updates its data regularly from ClinicalTrials.gov, so the information you see reflects current recruiting status. Always confirm details directly with the trial site before making plans. This guide is for informational purposes only. Always talk to your doctor about whether a clinical trial is right for you.
