Quick Summary
There are over 450,000 registered clinical trials worldwide — roughly 60,000 actively recruiting at any time. Proximity matters for frequent visits but is no longer a barrier for many studies. Decentralized trial designs, telemedicine visits, and travel reimbursement programs mean that the right trial for your condition may be hundreds of miles away — and that may still be worth exploring.
Step 1: Search by Location on ClinicalTrials.gov
ClinicalTrials.gov is the world's largest clinical trial registry with over 450,000 studies. To search by location:
- Go to clinicaltrials.gov and enter your condition in the search bar
- Click "More Filters" and scroll to the Location section
- Enter your ZIP code, city, or country and select a distance radius (25, 50, or 100 miles)
- Set Status to "Recruiting" — this is critical to filter out completed or not-yet-open studies
- Sort by "Relevance" first, then review the trial site locations in each result
Each trial listing shows the recruiting locations as a list of cities, countries, and institutions. A trial may have 20 sites — only one needs to be near you. Always check the full site list before concluding a trial isn't accessible.
Step 2: Understand Visit Frequency Before Applying
Not all trials require the same number of in-person visits. Before dismissing a trial as "too far," check the visit schedule in the protocol summary:
| Trial Type | Typical Visit Frequency | Remote Options |
|---|---|---|
| Phase 1 (safety) | Weekly or more during dosing | Limited — high monitoring needed |
| Phase 2/3 chronic disease | Monthly to quarterly | Often available for follow-up visits |
| Decentralized/hybrid | 1–2 in-person, rest remote | Yes — home nurse, app, wearables |
| Observational/registry | Annual or survey-based | Fully remote common |
Step 3: Ask About Travel Reimbursement
Travel costs are one of the biggest barriers to trial participation — but many sponsors cover them. What's reimbursable varies by trial and sponsor, but commonly includes:
- Mileage or fuel costs for driving to the trial site
- Public transport fares (train, bus, subway)
- Hotel accommodation for overnight stays, particularly for distant sites
- Flights — common in rare disease and oncology trials recruiting nationally
- Caregiver travel — many trials reimburse one accompanying person
- Childcare costs — some NIH-funded trials include these in compensation
Travel reimbursement is rarely advertised upfront — always ask the trial coordinator during your pre-screening call. The question to ask: "Does this trial provide travel reimbursement, and what does it cover?"
Decentralized Clinical Trials: When There's No Site Near You
Decentralized clinical trials (DCTs) bring the trial to the patient. In 2026, approximately 40% of new trials incorporate at least some decentralized elements. What this means for you:
- Home nursing visits: A trained nurse comes to your home for blood draws, vital signs, and drug administration — particularly common in Phase 2 oncology and rare disease trials
- Telemedicine check-ins: Video calls with the study doctor replace some in-person visits. Safety monitoring labs may be done at a local LabCorp or Quest Diagnostics
- Study drug delivery: Oral medications shipped directly to your home pharmacy. Injectables may be self-administered after training
- Wearables and e-diaries: Continuous heart rate monitoring, activity tracking, and smartphone symptom diaries replace clinic-based assessments for many endpoints
When searching for trials, look for terms like "decentralized," "hybrid," "remote," or "home visits" in the protocol description. Sponsors using decentralized designs often explicitly mention them in the eligibility section.
Finding Trials Through Patient Networks
ClinicalTrials.gov is comprehensive but difficult to navigate. Alternative resources for finding local trials:
- ResearchMatch.org: NIH-funded platform that matches patients to relevant trials through participating university hospitals
- Patient advocacy organizations: Disease-specific groups (NORD, NAMI, ACS, CCFA) maintain trial locators and can alert you when trials open at nearby sites
- Academic medical centers: Major university hospitals (Mayo Clinic, Johns Hopkins, UCSF, UCL, Charité) run more trials per institution than community hospitals — worth travelling to for initial evaluation
- Your specialist: Oncologists, neurologists, and rheumatologists at academic practices are typically connected to research networks and can refer you to trials before they appear publicly on registries
When No Local Trial Exists: Next Steps
Register your interest early. Many trials have a pre-registration or waitlist system. When a new site opens near you, patients who registered interest are contacted first.
Ask about expanded access. If a drug you're interested in is in Phase 3 trials but no site is near you, the manufacturer may offer expanded access (compassionate use) through your own physician. This is not a trial but provides access to the drug before approval.
Consider a one-time distant visit. Some trials allow remote follow-up after an in-person baseline. Flying to a distant site once for enrollment — then completing follow-up via telemedicine — may be worth it for a high-priority treatment.
