Joining a clinical trial abroad can feel daunting, but the path is more orderly than most people expect. The key principle: nothing is booked, and no travel happens, until a trial team confirms you may qualify. Here's how it usually goes.

Step 1 — Share your situation

It starts with the basics: your diagnosis, the treatments you've already tried, and where you live. This lets a coordinator narrow down which recruiting trials are even worth considering for your case, before anyone gathers detailed records.

Step 2 — Gather your medical records

To assess eligibility, trial teams generally need:

  • A medical summary in English
  • Pathology reports confirming the diagnosis
  • Imaging — CT, MRI, or PET scans (often the original files, not just printouts)
  • A record of prior treatments and how you responded

Coordinators often help with translation and organizing these documents.

Step 3 — Remote eligibility review

The trial team reviews your records remotely and decides whether you may be eligible under their protocol. This is the gate that matters — and it happens before you spend anything on travel. If a trial can't accept you, a good coordinator will tell you honestly and look at alternatives.

Important: eligibility is decided solely by the trial's investigators, not by any agency or coordinator. No one can promise you a spot in advance. Be wary of anyone who does.

Step 4 — Invitation and logistics

If a trial confirms you may be a candidate, you typically receive an invitation letter, which supports your visa application. From there, you plan the practical side: the appropriate visa for medical travel, flights, accommodation for a multi-week stay, and translation support. Requirements vary by nationality and change over time, so confirm current rules for your country.

Step 5 — Treatment and monitoring

On arrival, the center confirms eligibility with in-person tests before treatment begins. CAR-T involves a stay of several weeks with close monitoring; a proton therapy course runs across many sessions over several weeks. Larger centers usually have international departments that handle day-to-day coordination.

Step 6 — Follow-up back home

After treatment, you return home with your complete records — pathology, imaging, dose details, and follow-up instructions — so your local oncologist can continue your care. Arrange this handover in advance; continuity of follow-up is one of the most important parts of treatment abroad.

Where to start

You don't need to figure all of this out alone. Send your diagnosis and history below for a free eligibility review, and a coordinator will tell you whether a trial could realistically fit — and walk you through the steps if it does. Keep your treating oncologist involved throughout.
