Summary

This trial is looking at using a drug called venetoclax in combination with either obinutuzumab or acalabrutinib to treat chronic lymphocytic leukemia (CLL

Who is the study for?
Adults with previously untreated chronic lymphocytic leukemia (CLL) who need treatment and have a life expectancy over 6 months. They should be able to perform daily activities with ease or some difficulty (ECOG <=2), have good marrow function, and adequate kidney function (CrCl >=30 mL/min). Those with very large lymph nodes (>5 cm) and lower kidney function (CrCl <80 mL/min) can't join.
What is being tested?
The trial is testing the safety of venetoclax combined with obinutuzumab or acalabrutinib in treating CLL. Participants are divided into four groups receiving different combinations and dosing schedules of these drugs orally or through IV infusion. The study will last about 28 months across roughly 80 global sites.
What are the potential side effects?
Potential side effects include tumor lysis syndrome, where cancer cells break down rapidly causing complications; reactions related to IV infusions; digestive issues; fatigue; blood cell count changes; and possible infections due to weakened immune response.
