Summary

This study tested a combination of two targeted drugs, tafasitamab and parsaclisib, in 54 adults with relapsed or refractory non-Hodgkin lymphoma or chronic lymphocytic leukemia. The goal was to see if the combination was safe and could shrink tumors. However, the trial was terminated early, so the full results are not available.

What this could mean

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

Active substance
tafasitamab (a targeted antibody) and parsaclisib (a targeted pill)
What this could lead to
If successful, this combination could offer a new treatment option for people with blood cancers that have stopped responding to standard therapies.
What could go wrong
This was a very early (Phase 1b/2a) trial that was terminated early, so we don't know if the combination is safe or effective. Side effects from these drugs can be serious.
