-
High-precision detection of leftover cancer using a liquid-biopsy platform (SHERLOCK)
This project will test whether sensitive blood and other fluid tests for circulating tumor DNA can find leftover cancer (minimal residual disease) in adults treated with curative intent for breast, lung, melanoma, gynecologic, or genitourinary cancers.
-
Using genome and RNA analysis to guide treatment for advanced rare cancers
This project will test whether using detailed tumor DNA, RNA and methylation analyses to guide treatment helps adults with advanced rare cancers respond better than standard care.
-
Registry of patients with rare cancers in Korea
This study is collecting information from patients with rare cancers in Korea to see how they can take part in clinical research and improve future treatments.
-
Vaccination with Dendritic Cells for Patients with Resected Stage IV Rare Cancers
This study is testing a new vaccine made from patients' own immune cells to see if it can help people who have had rare stage IV cancers feel better and stay healthy after surgery.
-
Investigating genetic reasons for unusual responses to cancer treatment
This study is trying to find out how genetic differences in cancer patients affect their responses to treatment, so doctors can tailor therapies to work better for each individual.
-
Collecting tumor samples to improve cancer treatment matching
This study is collecting tumor samples from patients with advanced cancer to see if analyzing their genes can help doctors find the best treatments for them.

Quick answers
How many Rare Cancer clinical trials are recruiting right now?
6, as of November 12, 2026. We update this list each time we refresh our data from ClinicalTrials.gov.
Where are these trials running?
In 4 countries. The most sites are in Canada (3 trials), Germany (1 trial), Italy (1 trial), South Korea (1 trial). Each study page lists its sites and which ones are recruiting.
What phases are they in?
Phase 2: 1. Trials with no phase listed are usually device, behavioural or observational studies.
How do I join one?
Open a study, check the "Is this trial a fit for you?" section, then contact the study team listed on the page. They will ask a few screening questions. Asking is free and does not commit you to anything. Talk it over with your doctor first.
