Safety Study of VH4770359 in Healthy Adults
This is an early-stage safety study testing a new investigational drug (VH4770359) in healthy volunteers. Researchers want to understand how the body processes the drug and ensure it is safe and well-tolerated.
Baltimore, MarylandAges 18–55 - NCT07302347RecruitingPhase 1/Phase 2
Study of pembrolizumab for different cancers in Japan
This trial tests a drug called pembrolizumab (Keytruda) to see if it helps people with several types of cancer, including relapsed or refractory lymphoma, melanoma, MSI-high or TMB-high solid tumors, and Merkel cell carcinoma. The goal is to understand if this immunotherapy can shrink or control the cancer.
Nagoya, Aichi-kenAges 6 months+ - NCT04935684RecruitingPhase 2
Fecal transplant after bone marrow transplant to improve gut health
This Phase 2 study tests whether a fecal microbiota transplant (a processed transplant of gut bacteria) after an allogeneic bone marrow transplant is safe and helpful. Participants may benefit by improving recovery in the gut microbiome during the post-transplant period.
AmiensAges 18 years+ - NCT04936854RecruitingPhase 2
Sirolimus or steroid drops for active Graves eye disease
This Phase 2 study compares sirolimus versus corticosteroids to treat active thyroid eye disease. It aims to see which treatment works better to calm eye inflammation and improve symptoms, without needing urgent eye surgery.

Abemaciclib for Kaposi sarcoma in people with or without HIV
This Phase 1/2 study tests the medicine abemaciclib to shrink Kaposi sarcoma (KS) lesions and control the disease. It includes both people with HIV and people without HIV, and may help when KS has not responded well to prior treatment or when certain KS stages are present.
Bethesda, MarylandAges 18–99 - 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+ - NCT04947618Recruiting
Lymphoma management study at Nimes Hospital (1999-2018)
This trial looks back at how patients with lymphoma were treated at Nimes University Hospital between 1999 and 2018. It aims to better understand the disease and improve care by studying stored tumor samples.
Nîmes, GardAges 15 years+ - NCT04951622RecruitingPhase 3
Testing nipocalimab for adults with generalized myasthenia gravis
This Phase 3 study tests nipocalimab, a medication given by infusion (and in some groups by injections under the skin), to improve symptoms in adults with generalized myasthenia gravis (MG). It may help reduce weakness in daily activities, especially if you meet specific symptom and safety criteria.
Paradise Valley, ArizonaAges 18 years+ - NCT04955899Recruiting
Testing a device that stimulates the spleen in rheumatoid arthritis
This trial studies whether splenic stimulation (using a medical device to stimulate the spleen) is safe for people with active rheumatoid arthritis. It may help some patients who have not improved enough after at least two other advanced arthritis medicines.
AmsterdamAges 22–75 - NCT04957901Recruiting
Tracking a blood marker in children with lymphoma
This study checks whether measuring a blood test called “circulating tumor DNA” (ctDNA) helps monitor childhood lymphoma during treatment. It’s meant to see if ctDNA tracking can provide useful information alongside standard exams.
GuangzhouAges 1–18 - NCT04958122RecruitingPhase 3
Antibiotic treatment trial for early syphilis
This Phase 3 study tests whether cefixime can treat primary, secondary, or early latent syphilis. It may help by offering another effective antibiotic option, including for some people who also have HIV (if well controlled).
Los Angeles, CaliforniaAges 18 years+ - NCT04959175RecruitingPhase 1/Phase 2
Lower post-transplant drug doses for older or unfit patients
This trial tests whether giving a lower dose of cyclophosphamide after a bone marrow transplant can be safer for older or medically “unfit” patients, while still helping control blood cancers. It is designed for people who can’t tolerate the usual strongest transplant preparation.
Bethesda, MarylandAges 12–85 - NCT04963777Recruiting
Prebiotics for gut health in young people with type 1 diabetes
This trial studies whether taking prebiotics can change gut bacteria (gut microbiome) in people with type 1 diabetes. The goal is to see if these gut changes are linked to better health or diabetes-related outcomes.
Calgary, AlbertaAges 7 years+ - NCT04968288Recruiting
Study of the natural course of KSHV-related Castleman disease
This study looks at how KSHV-associated multicentric Castleman disease naturally progresses over time, without necessarily testing a new treatment. It may help doctors better understand the disease and what changes to watch for, which could guide future care.
Bethesda, MarylandAges 18 years+ - NCT04968899RecruitingPhase 3
IgG IV plus prednisone versus high-dose dexamethasone for ITP
This Phase 3 study compares two ways of treating immune thrombocytopenia (ITP) to raise blood platelet counts and reduce bleeding. It tests whether IgG given through a vein plus prednisone works better (or safer) than high-dose dexamethasone.
CréteilAges 18–80 - NCT04972942RecruitingPhase 1
Immunotherapy for high-risk T-cell blood cancers after transplant
This Phase 1 study tests a targeted immune treatment given after strong pre-treatment (myeloablative chemo plus total-body radiation) before or along with an allogeneic stem cell transplant. It may help prevent the cancer from coming back in young people with high-risk T-cell ALL or certain T-cell lymphomas.
Phoeniz, ArizonaAges Up to 39 years - NCT04976465RecruitingPhase 1
SLE Treatment During Pregnancy Study
This Phase 1 study looks at a treatment plan for people with systemic lupus (SLE) during pregnancy and tracks health outcomes for mother and baby. It may help doctors learn how to manage SLE safely in pregnancy and what results to expect.
Jinan, ShandongAges 20–45 - NCT04978948Recruiting
Study of a blood protein level in autoimmune disease
This study looks at how a specific protein on cell surfaces (called STIM1) appears in people with autoimmune diseases. The goal is to understand what affects this protein and how it may relate to autoimmune illness.
Brest, BrestAges 18–99 - NCT04981145RecruitingPhase 4
Iguratimod for Sjögren’s syndrome symptoms and safety
This trial studies whether iguratimod improves symptoms in people with primary Sjögren’s syndrome, and checks how safe it is. It focuses on people with confirmed disease markers (anti-SSA/Ro-60) and ongoing dry eyes and dry mouth.
Hangzhou, ZhejiangAges 18–70 - NCT04986293Recruiting

Choice-based trial of RA medicines with filgotinib or TNFi
This Phase 4 study compares two treatment options for rheumatoid arthritis (RA): filgotinib or a TNF inhibitor (TNFi). It is designed for adults whose current “standard” RA tablets have not worked well or were not tolerated, to see which approach improves RA control.
LeeuwardenAges 18–101 - NCT04988555RecruitingPhase 1/Phase 2
Study of an investigational drug for high-risk acute leukemia
This Phase 1/2 study tests enzomenib (DSP-5336) in people with relapsed or hard-to-treat acute leukemia (and, in some places, certain other blood cancers). The goal is to see how the drug works and how safe it is, especially for leukemia cases with specific genetic changes (KMT2A/MLL or NPM1).
Newport Beach, CaliforniaAges 12 years+ - 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.
