NCT ID NCT05618327

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-stage study is testing an experimental drug called JS203 in about 104 people with relapsed or refractory B-cell non-Hodgkin's lymphoma, a type of blood cancer. The main goals are to check the drug's safety, find the right dose, and see if it shows any signs of shrinking tumors. Participants receive the drug through an IV on a schedule that depends on the dose group they are assigned to.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

JS203 (an experimental drug for injection)

What this could lead to

If successful, this could lead to a new treatment option for patients with B-cell non-Hodgkin's lymphoma that has not responded to other therapies.

What could go wrong

This is an early Phase 1 trial with only 104 participants, so the drug may not prove effective or safe in larger studies. Side effects are unknown and could be serious.
