New blood test may predict immunotherapy success in cancer patients
NCT ID NCT02840058
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether measuring specific immune responses (anti-telomerase T cells) in the blood can help predict how well cancer patients will respond to immunotherapy drugs like anti-PD1/PDL1. Researchers enrolled 295 adults with advanced or metastatic cancer who were about to start such treatment. The goal was to see if these immune markers could serve as a tool to forecast treatment effectiveness.
