Recruiting studies
- 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.
Bullhead City, ArizonaAges 18 years+ - NCT05672251RecruitingPhase 2
Testing two antibody drugs for lymphoma that came back
This Phase 2 trial tests two targeted antibody medicines—loncastuximab tesirine and mosunetuzumab—in people whose diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma grade 3B has come back or did not respond. It aims to shrink lymphoma that has measurable disease and has specific markers (CD19 and CD20) on tumor cells.
Duarte, CaliforniaAges 18 years+ - NCT05602363RecruitingPhase 1
Docirbrutinib for CLL or lymphoma after prior treatments
This Phase 1 study tests docirbrutinib, a targeted pill treatment, in people with CLL/SLL or certain other B-cell lymphomas that have come back or didn’t respond to earlier therapy. The goal is to see whether it’s safe and whether it can control the disease after standard treatments have failed.
Orange, CaliforniaAges 18 years+ - NCT05557695Recruiting
Acalabrutinib patient study for early access CLL in the UK
This observational study follows adults in the UK who started acalabrutinib through an early access program for chronic lymphocytic leukemia (CLL). It aims to learn what happens in real-world care after starting the medicine.
AylesburyAges 18–130 - NCT05417165RecruitingPhase 2
Pneumococcal vaccine plan for CLL or SLL patients
This Phase 2 study tests a specific plan for giving a pneumococcal vaccine in people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). It may help improve protection against pneumococcal infections in patients who have not started CLL/SLL treatment yet.
Columbus, OhioAges 18 years+ - NCT05418088RecruitingPhase 1
CAR T-cell therapy for hard-to-treat B-cell cancers
This Phase 1 study tests lab-made immune cells (CAR T-cells) that target CD19, CD20, and/or CD22 in people with certain relapsed or refractory B-cell cancers. It may help by attacking cancer cells that still carry these targets, but eligibility is very specific and includes prior treatments and health/lab requirements.
Columbus, OhioAges 2 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+ - NCT05326308Recruiting
Zanubrutinib treatment in several blood cancers
This non-interventional study looks at outcomes for people with certain slow-growing blood cancers who are treated with zanubrutinib, with specific add-on use of obinutuzumab for follicular lymphoma. It may help doctors understand how this treatment is working in real-world care across several cancer types.
SalzburgAges 18 years+ - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Anchorage, AlaskaAges 40–75 - NCT05322850RecruitingPhase 1/Phase 2
Engineered donor stem cell transplant for childhood blood cancers
This trial tests a new way to prepare donor stem cells before a transplant for children and young adults with blood cancers. The goal is to make the transplant safer and more effective, potentially reducing complications like graft-versus-host disease.
Gainesville, FloridaAges Up to 50 years - NCT05336812RecruitingPhase 2
Acalabrutinib with venetoclax or obinutuzumab for untreated CLL
This Phase 2 trial studies how well acalabrutinib works when combined with either venetoclax or obinutuzumab in people with untreated chronic lymphocytic leukemia (CLL). It aims to improve disease control while checking safety and tolerability.
Columbus, OhioAges 18 years+ - NCT05254743RecruitingPhase 3
Pirtobrutinib versus ibrutinib for CLL or SLL
This Phase 3 trial compares two oral medicines—pirtobrutinib and ibrutinib—in people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who need treatment. It’s designed to see which drug works better and is easier to take, especially for people with a specific genetic change in the cancer (17p deletion).
Anaheim, CaliforniaAges 18 years+ - NCT05147467RecruitingPhase 2
Trial of APG-2575 for returning or resistant CLL/SLL
This trial studies APG-2575 in people with CLL/SLL that has come back or is not responding to prior treatments. It may help shrink disease and improve control when standard options have stopped working.
Guangzhou, GuangdongAges 18 years+ - NCT05183854RecruitingPhase 2
Vaccine study for CLL patients to prevent pneumococcal infections
This trial tests a series of two pneumococcal vaccines (PCV20 and PPSV23) in people with CLL-related immune weakness. It aims to see how well the vaccines work and how safe they are for preventing serious lung infections.
Salt Lake City, UtahAges 18 years+ - NCT05091424RecruitingPhase 1
Mosunetuzumab with or without venetoclax for CLL
This Phase 1 study tests whether mosunetuzumab alone or with venetoclax is safe and effective for people with chronic lymphocytic leukemia (CLL) that came back or did not respond to prior treatment. It may help by controlling the CLL immune system response while also studying dosing and side effects.
Rochester, MinnesotaAges 18 years+ - NCT05131022RecruitingPhase 1
Study of NX-5948 for relapsed B-cell blood cancers
This Phase 1 study tests NX-5948 in adults whose B-cell cancers have come back or did not respond to prior treatment. It aims to find a safe dose and see how well the treatment works in different types of B-cell malignancies.
Duarte, CaliforniaAges 18 years+ - NCT05006716RecruitingPhase 1/Phase 2
New treatment for blood cancers that have returned
This trial tests a new pill, tacabrutideg, for blood cancers that have returned or not improved after earlier treatments. It may work for patients who have already tried a type of targeted therapy called a BTK inhibitor.
Birmingham, AlabamaAges 18 years+ - NCT04941716RecruitingPhase 2
Acalabrutinib plus venetoclax for hard-to-treat CLL/SLL
This Phase 2 trial studies whether combining acalabrutinib and venetoclax can shrink or control chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) that has come back or did not respond to prior treatment. It may help by attacking the cancer using two different medicines together.
Seattle, WashingtonAges 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.
La Jolla, CaliforniaAges 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+ - 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+ - 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+ - NCT04269902RecruitingPhase 3
Early treatment check for high-risk CLL/SLL
This Phase 3 trial studies an early treatment approach for people with high-risk CLL or SLL who have not yet needed standard therapy. It aims to see if treating earlier can improve outcomes while keeping side effects manageable.
Birmingham, AlabamaAges 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.
