Experimental cancer drug JNJ-70218902 tested in 82 patients
NCT ID NCT04397276
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase study tested a new drug called JNJ-70218902 in 82 people with advanced solid tumors, including prostate cancer. The drug works by redirecting the body's immune T cells to attack cancer cells. The main goals were to find a safe dose and check for side effects, not yet to prove the drug works against cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- JNJ-70218902 (a drug that redirects immune T cells to attack cancer)
- What this could lead to
- If it works, this could point toward a new treatment option for advanced solid tumors that have stopped responding to standard therapies.
- What could go wrong
- This is a very early phase 1 trial focused on safety and dosing, not yet on effectiveness. The drug may cause serious side effects or fail to shrink tumors.
