Recruiting studies
- 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+ - NCT04169737RecruitingPhase 2
Acalabrutinib and venetoclax for high-risk CLL or SLL
This trial tests whether acalabrutinib and venetoclax (with or without early obinutuzumab) can control chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). It is mainly for people whose disease is high-risk, has come back, or did not respond to earlier treatment.
Houston, TexasAges 18 years+ - NCT05645107RecruitingPhase 3
XEMBIFY plus usual care to prevent infections
This Phase 3 study tests whether XEMBIFY (an immune protein therapy) plus standard medical treatment can better prevent serious or repeated infections. It is for people with certain cancers of blood/immune systems who are already having trouble with infections.
Huntington Park, CaliforniaAges 18 years+ - NCT03986034RecruitingPhase 2
Venetoclax study in relapsed CLL using early tumor tracking
This trial tests how well venetoclax (a targeted pill for CLL) works in people whose CLL has come back or hasn’t responded. It also closely tracks early changes in the CLL cells to better understand what happens during treatment.
Bethesda, MarylandAges 18–85 - NCT03197259Recruiting
Chronic lymphocytic leukemia registry study for adults
This study collects information from people with chronic lymphocytic leukemia (CLL) to better understand the disease over time. If you join, you would share your medical and health details and give consent to be included in the registry.
IzmirAges 18 years+ - NCT03516617RecruitingPhase 2
Acalabrutinib with or without obinutuzumab for early CLL/SLL
This Phase 2 trial studies whether acalabrutinib, and optionally adding obinutuzumab, can control early-stage chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). It aims to see how well these treatments work and how safe they are in people who have not had prior treatment.
Scottsdale, ArizonaAges 18 years+ - NCT03666000RecruitingPhase 1
Testing a CD19 CAR T cell treatment for relapsed blood cancers
This Phase 1 study tests the safety and best dose of a CD19 CAR T cell therapy (azer-cel) in people whose B-cell blood cancer has returned or did not respond to treatment. It may help people with relapsed/refractory B-ALL or certain aggressive or large B-cell lymphomas, including after or before prior CAR T treatment.
Gilbert, ArizonaAges 18 years+ - NCT03676504RecruitingPhase 1/Phase 2
CAR T cell therapy for relapsed CD19 blood cancers
This trial tests a type of personalized immune treatment (CD19 CAR T cells made from your T cells) for adults (and children with ALL) whose CD19-positive blood cancer has come back or didn’t respond. It may help your immune system recognize and attack cancer cells that still have CD19.
HeidelbergAges 3 years+ - NCT03824483RecruitingPhase 2
Testing three drugs for CLL, SLL, or mantle cell lymphoma
This Phase 2 study tests zanubrutinib, obinutuzumab, and venetoclax together in people with chronic lymphocytic leukemia (CLL), small lymphocytic leukemia (SLL), or mantle cell lymphoma (MCL). It aims to shrink cancer and improve control of the disease, especially when treatment choices are limited.
Evanston, IllinoisAges 18 years+ - NCT05371808Recruiting
Early vs delayed treatment for high-risk CLL: cost study
This study compares early treatment versus delaying treatment in newly diagnosed people with high-risk CLL/SLL who feel well. It mainly looks at the overall “costs and value” of each approach and asks patients to complete short health and quality-of-life questionnaires.
Vancouver, British ColumbiaAges 18 years+ - NCT04028531Recruiting
Understanding chronic lymphocytic leukemia in clinic patients
This study aims to learn more about chronic lymphocytic leukemia (CLL) and closely related conditions. It may help researchers better understand who gets CLL and how it behaves over time, which can improve future care.
Boston, MassachusettsAges 18 years+ - NCT04195633RecruitingPhase 2
Haploidentical donor stem cell transplant to treat blood cancers
This Phase 2 trial tests whether a specific stem cell transplant method (from a related “half-matched” donor) plus conditioning chemo and radiation can improve outcomes for several blood cancers. It may help people whose cancer is in remission but still considered high risk, or those who have had limited response after prior treatment.
Seattle, WashingtonAges 6 months+ - NCT04494503RecruitingPhase 1/Phase 2
Study drug for hard-to-treat CLL or SLL after relapse
This Phase 1/2 study tests APG2575 alone or combined with other treatment in people whose CLL/SLL has come back or did not respond to prior therapy. The goal is to see how well the treatment works and how safe it is.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04560322RecruitingPhase 2
Test of venetoclax and obinutuzumab with or without acalabrutinib
This Phase 2 study tests venetoclax plus obinutuzumab, and whether adding acalabrutinib (or not) improves outcomes for people with relapsed or refractory CLL/SLL. It aims to see which combination works best and is safe for patients whose leukemia has returned or not responded.
Boston, MassachusettsAges 18 years+ - NCT04704323RecruitingPhase 1
CAP-100 drug study for hard-to-treat CLL after prior treatments
This early-phase (Phase 1) study tests CAP-100 in adults with CLL or SLL that has come back or did not respond to at least two previous treatments. The goal is to see how the drug works and whether it is safe enough to keep studying.
Boston, MassachusettsAges 18 years+ - NCT04758975RecruitingPhase 2
Venetoclax plus rituximab plus ibrutinib for early CLL
This Phase 2 trial tests a combination of three medicines to treat chronic lymphocytic leukemia (CLL) that has not been treated before and where the goal is to achieve very low remaining disease. It may help some people stay in remission longer, but eligibility depends on your age, organ function, and prior treatments.
Milan, MIAges 18–65 - NCT04771572RecruitingPhase 1
Oral drug LP-118 for relapsed blood cancers
This Phase 1 study tests an oral (by mouth) drug called LP-118 in people whose blood cancers have returned or did not respond to prior treatment. The goal is to find a safe dose and see whether it can shrink or control the cancer.
Chicago, IllinoisAges 13 years+ - NCT04771507RecruitingPhase 1/Phase 2
Testing intermittent ibrutinib for advanced chronic lymphocytic leukemia
This trial studies whether taking ibrutinib in a less continuous (“intermittent”) schedule can keep your chronic lymphocytic leukemia (CLL) under control. It’s for people who have already received ibrutinib for at least 6 months and had a good early response, aiming to reduce treatment intensity while tracking safety and cancer control.
TrondheimAges 18 years+ - NCT04785989Recruiting
Blood and marrow testing to study metabolism in CLL
This study measures how your body’s metabolism works in people with chronic lymphocytic leukemia (CLL). It uses blood tests, and for some people, a bone marrow sample, to better understand what’s happening and potentially guide future treatments.
Madison, WisconsinAges 18 years+ - NCT04830137RecruitingPhase 1
Test drug NX-2127 for hard-to-treat B-cell blood cancers
This Phase 1 trial tests the safety and early effectiveness of NX-2127 in adults with relapsed or refractory B-cell cancers. If you qualify, you may receive a new targeted treatment because your cancer has returned or not responded to prior therapies.
Duarte, CaliforniaAges 18 years+ - NCT04844528RecruitingPhase 2
Nicotinamide for CLL patients with recent skin cancer history
This Phase 2 trial tests whether nicotinamide (a form of vitamin B3) can help people with chronic lymphocytic leukemia (CLL) who have had non-melanoma skin cancers in the past 5 years. The study looks at how well new skin cancers can be prevented or reduced.
Salt Lake City, UtahAges 18 years+ - NCT04867915Recruiting
Study of CLL, SLL, and related blood conditions in Italy
This is a study that looks back and forward at people diagnosed with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), or a related early condition called MBL. It aims to improve how these conditions are recognized and managed over time in Italy.
AlessandriaAges 18 years+ - NCT04892277RecruitingPhase 1
CD19 CAR-T for adults with hard-to-treat B-cell cancers
This Phase 1 trial tests a lab-made immune therapy (CD19 CAR-T) for adults whose B-cell cancers have come back or did not respond to treatment. It may help your immune system better recognize and attack cancer cells, but it is early research, so benefits and risks are still being defined.
Rochester, MinnesotaAges 18 years+ - NCT04895436RecruitingPhase 2
Oral venetoclax plus IV obinutuzumab after prior CLL treatment
This trial tests whether adding oral venetoclax together with an IV antibody called obinutuzumab can control CLL when the disease comes back after a specific prior treatment. It also looks closely at side effects to see what changes in “disease activity” and safety to expect.

Common questions
- Are there clinical trials for chronic lymphocytic leukemia?
- Yes. Clin2 currently lists 203 recruiting chronic lymphocytic leukemia studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a chronic lymphocytic leukemia trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a chronic lymphocytic leukemia trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
