Promising cancer drug trial halted early – only 3 patients enrolled
NCT ID NCT04486391
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a drug called tislelizumab, which helps the immune system fight cancer, against standard chemotherapy in people with Hodgkin lymphoma that returned or didn't respond to treatment. Only 3 people took part before the study was stopped early. Because of this, we don't have enough information to know if tislelizumab works better or is safer than chemotherapy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tislelizumab (a type of immunotherapy that helps the immune system attack cancer cells)
- What this could lead to
- If it works, this could offer a new treatment option for people with Hodgkin lymphoma that hasn't responded to other therapies.
- What could go wrong
- The trial was terminated early with only 3 participants, so we have very little data. It's unclear if tislelizumab is effective or safe compared to standard chemotherapy.
