Recruiting studies
- NCT05052528RecruitingPhase 1
CAR T cell therapy for relapsed or refractory large B-cell lymphoma
This trial tests whether adding a targeted antibody (rituximab) before CAR T cell therapy improves outcomes for patients with diffuse large B-cell lymphoma that has come back or not responded to at least two prior treatments.
Sacramento, CaliforniaAges 18 years+ - NCT03394365RecruitingPhase 3
Tabelecleucel for EBV-related lymphoma after transplant treatment failure
This trial tests tabelecleucel, an immune therapy, for people whose EBV-associated post-transplant lymphoproliferative disease (PTLD) did not respond to rituximab and/or chemotherapy. It may help your immune system better control EBV-driven lymphoma after a transplant.
Duarte, CaliforniaAges Any age - NCT03523975RecruitingPhase 1/Phase 2
Testing venetoclax, lenalidomide, and rituximab for new mantle cell lymphoma

Duarte, CaliforniaAges 18 years+ - NCT03844061RecruitingPhase 2
Belimumab plus rituximab for early diffuse scleroderma skin disease
This Phase 2 study tests whether combining belimumab and rituximab can improve skin thickening in people with early diffuse cutaneous systemic sclerosis (dcSSc). It may help slow the disease process and improve skin symptoms, but it also requires screening for immune and infection risks.
New York, New YorkAges 18–80 - NCT03949855RecruitingPhase 2
Belimumab plus rituximab for primary membranous nephropathy
This study tests whether adding belimumab to rituximab helps people with primary membranous nephropathy (a kidney disease) that has the right blood test marker and specific protein levels. The goal is to improve kidney outcomes and reduce disease activity while keeping treatment safe.
Birmingham, AlabamaAges 18–75 - NCT04421560RecruitingPhase 1/Phase 2
Testing pembrolizumab, ibrutinib, and rituximab for PCNSL
This Phase 1/2 study tests how well a combination of pembrolizumab, ibrutinib, and rituximab treats primary CNS lymphoma that came back or didn’t respond after prior brain treatment. It may help shrink the lymphoma and control it in the brain and fluid around the brain.
Boston, MassachusettsAges 18 years+ - NCT04518475RecruitingPhase 4
Eltrombopag with rituximab versus eltrombopag alone for ITP
This trial compares two treatment approaches for adults with primary immune thrombocytopenia (ITP), a condition where platelet counts are too low. It looks at whether adding rituximab to eltrombopag helps control ITP better and more safely.
TianjinAges 18–60 - 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 - NCT04989621RecruitingPhase 2
Orelabrutinib plus rituximab for relapsed follicular lymphoma
This Phase 2 study tests whether orelabrutinib combined with rituximab, followed by orelabrutinib alone for a while, can control follicular lymphoma that has come back or did not respond. It may help shrink tumors and keep the disease from worsening after initial response.
Guangzhou, GuangdongAges 18 years+ - NCT04989491RecruitingPhase 4
Single-dose rituximab to prevent EBV after kidney transplant
This trial tests whether one dose of rituximab (given around the time of transplant) can help prevent a first Epstein-Barr virus (EBV) infection and related abnormal lymph node or immune growths after kidney transplant. It is specifically for adults who are EBV-negative before receiving an EBV-positive donor kidney.
StrasbourgAges 18 years+ - NCT04998669RecruitingPhase 2
Loncastuximab plus rituximab for relapsed follicular lymphoma
This Phase 2 study tests whether loncastuximab, combined with rituximab, can shrink and control follicular lymphoma that has come back or not responded to prior treatment. It may help people who still have active disease that needs treatment and meet specific scan and blood test requirements.
Fort Myers, FloridaAges 18 years+ - NCT05018520RecruitingPhase 3
Two chemotherapy schedules for newly diagnosed low-risk DLBCL
This trial compares two different shortened treatment schedules of R-CHOP to see which one is safer and works better for people with low-risk diffuse large B-cell lymphoma (DLBCL). It aims to reduce risk from treatment while maintaining strong cancer control after an initial response.
Shanghai, Shanghai MunicipalityAges 14–75 - NCT05099471RecruitingPhase 2
Venetoclax plus rituximab for Waldenström’s macroglobulinemia
This Phase 2 study tests whether the combination of venetoclax and rituximab works better for Waldenström’s macroglobulinemia (WM) than expected from standard approaches. It is for adults with WM who have symptoms or organ/health problems caused by the disease.
BielefeldAges 18 years+ - NCT05249959RecruitingPhase 2
Loncastuximab after short treatment for relapsed mantle cell lymphoma
This Phase 2 trial studies whether adding loncastuximab after a short course of standard immunochemotherapy can better control mantle cell lymphoma that came back or didn’t respond. It specifically targets people who previously received a BTK inhibitor (or couldn’t tolerate it).
Brescia, ItalyAges 18–79 - NCT05389423RecruitingPhase 1
Pomalidomide plus chemotherapy for HIV-related lymphoma
This Phase 1 study tests whether a combination of pomalidomide and a dose-adjusted chemotherapy plan (EPOCH), with or without rituximab, can treat certain aggressive B-cell lymphomas in people living with HIV. It aims to find a safe dosing approach and see how well the treatment works for specific lymphoma types or high risk of spread to the brain.
Bethesda, MarylandAges 18 years+ - NCT05583071RecruitingPhase 2
Testing a four-drug plan for primary brain lymphoma
This Phase 2 trial studies methotrexate, tafasitamab, lenalidomide, and rituximab for primary B-cell lymphoma that starts in the brain/spinal fluid. It aims to see how well this combination works for people who cannot have certain high-dose stem cell treatment.
Stuttgart, Baden-WurttembergAges 18–99 - NCT05596786RecruitingPhase 3
Rituximab for worsening inflammatory lung scarring
This trial studies whether rituximab can slow worsening lung scarring (interstitial lung disease) when there is an inflammatory component. You would get rituximab or a placebo (inactive treatment) in a blinded, randomized design to compare safety and effectiveness.
ToursAges 18–100 - NCT05635162RecruitingPhase 2
Zanubrutinib plus rituximab for slow-growing mantle cell lymphoma
This trial studies whether combining zanubrutinib and rituximab can better control indolent (slow-growing) mantle cell lymphoma. It aims to improve how long participants can stay without the lymphoma worsening.

Chemo plus targeted antibodies for relapsed childhood B-ALL
This Phase 2 study tests a combination treatment for children, teens, or young adults whose B-cell acute lymphoblastic leukemia (B-ALL) has come back or did not respond to initial therapy. It may help patients who cannot safely receive certain standard medicines like anthracyclines or who cannot tolerate PEG-asparaginase.
Houston, TexasAges 1–25 - NCT05728658RecruitingPhase 1
Study of ICP-248 for relapsed or refractory B-cell cancers
This early-phase (Phase 1) study tests ICP-248 in people with certain B-cell cancers that have come back (relapsed) or did not respond to prior treatment (refractory). The goal is to learn the safest dose and whether it can help shrink or control the cancer.

Epcoritamab and rituximab for untreated follicular lymphoma
This phase 2 trial tests whether a combination of epcoritamab plus rituximab can work as a first treatment for follicular lymphoma. It may help people whose lymphoma is causing symptoms or affecting organs, or who have bulky disease, by targeting the lymphoma cells.
Boston, MassachusettsAges 18 years+ - NCT05786768RecruitingPhase 2/Phase 3
Obinutuzumab vs rituximab for relapsing childhood kidney syndrome
This study compares two antibody medicines, obinutuzumab and rituximab, to prevent relapses of steroid-dependent or frequently relapsing nephrotic syndrome in children. It looks at whether one option works better and is safer, including infection risk.
ParisAges 3–18 - NCT05834855RecruitingPhase 3
Rituximab versus ocrelizumab for relapsing multiple sclerosis
This Phase 3 trial compares two similar immune therapies—rituximab and ocrelizumab—to see if rituximab works about as well for relapsing multiple sclerosis. It may help you and researchers understand which option is equally effective and safe for preventing relapses and disease activity.
