New combo therapy targets hard-to-treat solid tumors
NCT ID NCT06781125
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new drug, JCXH-211, injected directly into tumors along with an anti-PD-1 antibody given through an IV. It is for people with advanced solid tumors that have stopped responding to standard treatments. The goal is to see if the combination is safe and tolerable for up to 72 participants.
