Recruiting studies
- 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.
Springdale, ArkansasAges 18 years+ - NCT06973187RecruitingPhase 3
Comparing two drugs for CLL or SLL after prior treatment
This trial tests a new drug (BGB-16673) against another drug (pirtobrutinib) for people with CLL or SLL that hasn't responded to or has come back after a prior BTK inhibitor treatment. The goal is to see which drug is more effective and safe.
Birmingham, AlabamaAges 18 years+ - NCT07194980RecruitingPhase 2
Study of a pill and CAR T-cell therapy for CLL/SLL
This study tests a combination of two treatments: a targeted pill (nemtabrutinib) and a special immune cell therapy (lisocabtagene maraleucel, or liso-cel) for people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) that has come back or has not responded to previous treatment. The goal is to see if giving the pill first helps the cell therapy work better.
Seattle, WashingtonAges 18 years+ - NCT07342478RecruitingPhase 3
Comparing two BTK inhibitors for CLL/SLL after prior treatment
This study compares two oral targeted therapies, rocbrutinib and pirtobrutinib, for people with CLL or SLL whose disease has come back or stopped responding after treatment with a covalent BTK inhibitor (like ibrutinib). The goal is to see which drug works better and has fewer side effects.
Skokie, IllinoisAges 18 years+ - NCT06943872RecruitingPhase 3
Comparing new treatments for relapsed CLL or SLL
This study tests a combination of sonrotoclax plus obinutuzumab or rituximab versus the current standard venetoclax plus rituximab for people whose CLL or SLL has come back or not responded to previous treatment. The goal is to see which approach helps keep the cancer from growing longer.
Laguna Hills, CaliforniaAges 18 years+ - NCT06533579RecruitingPhase 1/Phase 2
Gene therapy for CD19-positive blood cancers
This trial tests a new gene therapy treatment for people with certain types of leukemia or lymphoma that have the CD19 marker and have not responded to other treatments. The therapy uses a virus to deliver a gene to target and kill cancer cells.
Duarte, CaliforniaAges 13–90 - NCT06735664RecruitingPhase 1
Zanubrutinib and odronextamab for Richter's transformation
This trial tests a combination of two targeted drugs for people with Richter's transformation, an aggressive lymphoma that can develop from CLL. The goal is to see if this combination can help control the disease.
Duarte, CaliforniaAges 18 years+ - NCT05873712RecruitingPhase 2
Zanubrutinib plus CAR-T for Richter syndrome
This Phase 2 trial tests whether a combination of zanubrutinib (an oral medicine) and CAR-T cell therapy can treat Richter syndrome, a type of lymphoma that develops in people with CLL/SLL. It may help shrink tumors and improve outcomes after the disease comes back or doesn’t respond to prior treatment.
New York, New YorkAges 18 years+ - NCT05366218RecruitingPhase 1/Phase 2
Tafasitamab for kids with high-risk B-cell leukemia after relapse
This Phase 1/2 study tests tafasitamab in children and teens with B-lineage acute lymphoblastic leukemia (ALL) that has come back or did not respond. It is mainly for patients with specific high-risk leukemia changes and/or leukemia markers that stay after stem cell transplant or CAR T-cell therapy.
Freiburg im Breisgau, Baden-WurttembergAges 3–18 - NCT06708897RecruitingPhase 1
Study of lonitoclax for returning B-cell blood cancers
This trial tests a new drug, lonitoclax, in people with certain B-cell blood cancers that have come back or not responded to earlier treatments. It aims to see if the drug can help control the disease.
Louisville, KentuckyAges 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+ - 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 - 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+ - NCT03850574RecruitingPhase 1/Phase 2
Tuspetinib for relapsed or hard-to-treat AML
This early-phase study tests tuspetinib in people with AML that has come back or did not respond to treatment. The goal is to learn whether it is safe and tolerable, how the drug behaves in the body, and whether it shows signs of benefit.
Birmingham, AlabamaAges 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+ - 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+ - 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+ - 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+ - 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+ - 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+ - NCT05246345Recruiting
Study for chronic lymphocytic leukemia after venetoclax failure
This study looks at why chronic lymphocytic leukemia may stop responding after a medicine called venetoclax. By analyzing tumor samples, researchers hope to better understand resistance and guide future treatment options.
AmiensAges 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+ - 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.
