Recruiting studies in California
- NCT05947851RecruitingPhase 3
Nemtabrutinib plus venetoclax versus standard add-on therapy
This Phase 3 study tests whether adding nemtabrutinib to venetoclax works better than the usual next treatment approach (venetoclax plus rituximab) in people with relapsed or treatment-resistant CLL/SLL. It may help by improving how well the cancer responds after at least one prior therapy.
Long Beach, CaliforniaAges 18 years+ - NCT07424833RecruitingPhase 1
Study of APG-3288 for Relapsed/Refractory Blood Cancers
This trial is testing a new drug called APG-3288 for people with certain relapsed or treatment-resistant blood cancers (like CLL/SLL, DLBCL, MCL, WM, MZL, or FL). You may qualify if you've tried at least 2 prior treatments and are looking for a new option.
Los Angeles, CaliforniaAges 18 years+ - NCT07321652RecruitingPhase 3
Sonrotoclax plus zanubrutinib for untreated CLL or SLL

What taking part in a chronic lymphocytic leukemia study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
