Summary

This trial is testing whether two different drugs, pentostatin and bendamustine, are more effective when combined with rituximab to treat hairy cell leukemia than rituximab alone.

Who is the study for?
Adults diagnosed with hairy cell leukemia that hasn't improved or has returned after standard treatments. They must have specific blood conditions, organ function within certain limits, and agree to birth control if applicable. Excluded are those with active infections, severe heart disease, HIV/hepatitis B/C, pregnant/nursing women, non-responsive to both drug combinations previously or unable to follow the trial procedures.
What is being tested?
The trial is testing whether rituximab combined with either pentostatin or bendamustine is more effective for treating hairy cell leukemia than rituximab alone. Participants will undergo four treatment cycles of 28 days each and receive these drugs on specified days while their health is closely monitored through tests and biopsies.
What are the potential side effects?
Potential side effects include reactions related to the immune system's response such as fever and chills (infusion reactions), low blood counts leading to increased infection risk or bleeding problems, liver enzyme changes indicating potential liver issues, fatigue from anemia or other causes related to treatment.
