NCT ID NCT06936943
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tests the drug nivolumab (Opdivo) in 14 people with Richter's transformation, a rare and aggressive blood cancer that arises from chronic lymphocytic leukemia. The study measures how many patients respond to treatment, how long they live, and safety. All participants receive nivolumab every 4 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- nivolumab (Opdivo)
- What this could lead to
- If it works, this could offer a new treatment option for Richter's transformation, a rare and aggressive blood cancer.
- What could go wrong
- This is a small, early-phase study with only 14 participants, so results may not apply broadly. Nivolumab can cause immune-related side effects.
