Clinical trial for Biliary Tract Cancers
Official title Targeting Driver Oncogenes With a Peptide Vaccine Plus Durvalumab and Tremelimumab for Patients With Biliary Tract Cancers (BTC)
ClinicalTrials.gov ID: NCT06564623
What this study is testing
What is mBTC vax?
An investigational peptide vaccine being studied as a potential treatment for biliary tract cancers. It is designed to stimulate the immune system to recognize and attack cancer cells by presenting mutant tumor peptides together with the immune‑activating adjuvant poly‑ICLC.
Also referred to as Peptide + Poly‑ICLC (Hiltonol).
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is testing whether a personalized peptide vaccine with an immune booster, combined with two immune‑boosting drugs, is safe and can trigger an immune response in patients with advanced biliary tract cancer.
- Who it's for
- You may be able to join if you have advanced biliary tract cancer and have finished first‑line treatment.
- What's involved
- You will receive a custom vaccine made from your own cancer cells, plus two drugs that help the immune system fight cancer. You will have regular visits for injections and blood tests.
- Time commitment
- The study lasts about 6 months, with visits every few weeks for injections, blood tests, and safety checks.
- Phase 1: an early, usually small safety study
