Promising combo trial halted early – too few patients to draw conclusions
NCT ID NCT05317936
First seen Nov 01, 2025 · Last updated Jun 20, 2026 · Updated 33 times
Summary
This small early-phase trial tested whether adding pirtobrutinib to venetoclax could wipe out leftover cancer cells in people with CLL/SLL who still had detectable disease after venetoclax alone. Only 3 people enrolled before the study was terminated, so we cannot draw any reliable conclusions about safety or effectiveness.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
pirtobrutinib and venetoclax
What this could lead to
If it works, this combination could help people with CLL/SLL achieve deeper remission by wiping out leftover cancer cells after standard treatment.
What could go wrong
The trial was terminated early with only 3 participants, so we have very little data. It is too early to know if the combination is safe or effective.
