Clinical Trials for Cancer Abroad: How to Access Experime...

Cancer Treatment · 2 · October 10, 2025

ClinicalTrials.gov lists over 48,000 active cancer trials worldwide — but 72% are US-based, and many require frequent on-site visits that exclude international patients. For patients who've exhausted standard treatments, international trial access can be life-changing.

Why Look Beyond Your Country for Trials

Three reasons patients seek trials abroad: (1) The specific trial isn't available domestically — many novel agents from Chinese and Indian biotech companies are trialed only in their home countries. (2) The patient has been excluded from domestic trials due to comorbidities, previous treatments, or limited trial slots. (3) The trial offers a treatment not yet approved in the patient's country — accessing tomorrow's medicine today.

How to Find International Cancer Trials

ClinicalTrials.gov is the global registry — filter by country, cancer type, phase, and recruitment status. The WHO International Clinical Trials Registry Platform (ICTRP) indexes trials from 17 national registries, including India's CTRI, South Korea's CRIS, and Japan's JPRN.

Practical tip: contact the oncology department at major cancer centers directly. India's Tata Memorial and HCG Cancer Centre run 200+ active trials. South Korea's Samsung Medical Center and Asan Medical Center are leading hubs for novel combination immunotherapy trials. Turkey's Acibadem is expanding its trial portfolio. Many centers have dedicated international trial coordinators who screen eligibility remotely.

Costs and Logistics of Trial Participation Abroad

Most clinical trials provide the investigational drug at no cost — but patients typically pay for travel, accommodation, and standard-of-care medical costs (imaging, blood work, hospitalizations). Some trials also provide stipends for travel. Budget $500-$2,000 per visit for travel-related costs. Trial participation usually requires 6-12 visits over 6-24 months. Some trials permit remote monitoring visits at local hospitals between required on-site assessments.
