Joining a clinical trial can feel like trying to solve a puzzle with missing pieces. Patients often find that even when they identify a promising match, a series of thorny factors—such as geographic incompatibility and financial constraints—prevent them from enrolling. The system is designed to be rigorous, but for many, the administrative and logistical hurdles are enough to keep them on the sidelines despite a genuine desire to help.
The Doctor’s Role in Finding Trials
Despite widespread interest, most patients don’t know how to find a trial. A survey of over 2,000 adults with chronic conditions found that 71% would be likely to participate if given the chance, yet two-thirds reported their healthcare providers had never discussed trials. Even doctors seem hesitant to make the referral. An online survey of primary care physicians showed that while 86% said they were likely to refer patients, only 37% had actually done so.

Doctors are busy professionals who must balance time constraints with the complexity of research. A community oncologist might have to search through databases like clinicaltrials.gov, filter results based on patient history, and then contact the site to verify enrollment. If the doctor manages to find a suitable option, they risk losing the patient to the trial site, creating a disincentive for the referral. Patients are often better off asking their healthcare providers directly about available opportunities.
Participation requires a significant time commitment. Trials often involve regular visits for blood draws, imaging, or questionnaires. For patients living in rural areas, the nearest academic medical center might be hundreds of miles away. A 2019 study of cancer patients found that over half didn’t have an available trial at their local facility. This geographic gap is a major barrier to access, as researchers need to see patients in person to monitor their progress and safety.
Money and Logistics Can Stop You
Costs are frequently the dealbreaker. While the drug or device being tested is usually free, the Affordable Care Act requires most commercial plans to cover routine patient costs. However, patients are still responsible for deductibles, copays, and coinsurance. If the trial site is out of network, the bill can be even higher. Medicare and Medicaid have similar coverage requirements, but they don’t cover incidental expenses.

Travel, parking, lodging, and childcare can quickly add up. Some trial sponsors pay for these incidental costs, but they rarely advertise them. Experts suggest patients take the initiative and ask about financial support. “There may in fact be help, and you should take advantage of it if it’s available,” said Wendy Selig. The financial toxicity of trials remains a major hurdle, forcing many to choose between their health and their livelihood.
Recently, there has been a push to modernize these barriers. In June, the Department of Health and Human Services announced an effort to streamline federal rules, specifically looking at whether sponsors should be allowed to pay for travel and lodging. In July, a group of nearly 200 advocacy groups urged Congress to pass the Clinical Trial Modernization Act. This legislation would allow sponsors to cover medical costs like insurance deductibles and nonmedical expenses like childcare. It would also exempt up to $2,000 in financial support from federal taxes, ensuring patients don’t lose eligibility for income-based programs like Medicaid.
