Study drugs for certain FLT3-mutated blood cancers that have returned
This trial tests a combination of three medicines—azacitidine, venetoclax, and gilteritinib—in people with specific gene changes (FLT3 mutations) in leukemia and related bone marrow diseases that have come back or are hard to treat. The goal is to see if this drug combination can control the disease and improve outcomes.
Houston, TexasAges 18 years+ - NCT03604315RecruitingPhase 1
PET/CT scan testing a new radioactive tracer for tumors
This early-phase study uses PET/CT scans to see how well a new radioactive tracer (a tiny dose of a special material) highlights solid tumors in the body. It may help researchers learn whether this tracer can better find and track tumor spots seen on standard scans.
Houston, TexasAges 18 years+ - NCT03670966RecruitingPhase 1/Phase 2
Targeted iodine therapy, then donor transplant for hard leukemias
This trial tests an antibody-linked radioactive iodine treatment, followed by a donor stem cell transplant, for people with relapsed or refractory high-risk acute leukemia or certain MDS. It may help patients by targeting leukemia cells and then using a new immune system to control the disease.
Seattle, WashingtonAges 18–75 - NCT03418038RecruitingPhase 2
Vitamin C with chemotherapy for lymphoma and blood disorders
This trial tests whether adding high-dose vitamin C (ascorbic acid) to standard chemotherapy helps treat lymphomas that have come back or not responded, as well as two related blood disorders (CCUS and CMML). The goal is to see if the vitamin C makes the chemo work better.
Mankato, MinnesotaAges 18 years+ - NCT03128034RecruitingPhase 1/Phase 2
Astatine-211 treatment before stem cell transplant for high-risk blood cancers
This trial tests a targeted radiation drug (Astatine-211) given before a donor stem cell transplant for people with high-risk leukemia or certain bone-marrow cancers. The goal is to better control the cancer before the transplant.
Seattle, WashingtonAges 18–75 - NCT03011814RecruitingPhase 1/Phase 2
Durvalumab plus lenalidomide for relapsed T-cell lymphoma
This study tests a combination of two drugs—durvalumab (an immunotherapy) and lenalidomide (a targeted therapy)—to see if they are safe and effective for people with T-cell lymphoma that has come back or not responded to treatment. It aims to harness your immune system to fight the cancer while also attacking the cancer cells directly.
Duarte, CaliforniaAges 18 years+ - NCT01790152Recruiting
Dexrazoxane study to monitor heart damage in cancer survivors
This study tests dexrazoxane (DRZ) to see how it affects blood and heart-related “biomarkers,” or measurable signs of heart damage, after cancer treatment. It mainly targets survivors who may be at risk for cardiomyopathy (heart muscle weakness) or related heart failure.
Birmingham, AlabamaAges Any age - NCT07437963RecruitingPhase 1/Phase 2
Iberdomide plus chemoimmunotherapy for neuroblastoma that returned or did not respond
This trial tests adding a new drug called iberdomide to an existing chemoimmunotherapy regimen for children and young adults with neuroblastoma that has come back or not responded to treatment. The goal is to see if the combination is safe and more effective than current treatments.
Oakland, CaliforniaAges 1–30 - NCT07509034RecruitingPhase 1
Targeted immune cells for recurrent small cell lung cancer
This trial tests a special immune cell therapy (CAR T cells) that targets a protein called B7-H3 on your cancer cells. It is for people with small cell lung cancer or similar neuroendocrine cancers that have returned or not responded to standard treatments.
Bethesda, MarylandAges 18–120 - NCT07513285RecruitingPhase 2
Ibezapolstat pill for recurrent C. difficile infection
This trial tests a new oral antibiotic called ibezapolstat to treat recurrent C. difficile infection (CDI)—a serious diarrheal illness caused by bacteria in your gut. The study focuses on patients who have had multiple CDI episodes and may benefit from a different treatment approach.
Sacramento, CaliforniaAges 18–90 - NCT04510051RecruitingPhase 1
CAR T cell therapy for IL13Rα2 positive pediatric brain tumors
This Phase 1 study tests a type of immune therapy (CAR T cells) for children with brain tumors that come back or do not respond to standard treatment. The cells are given after chemotherapy that temporarily lowers the body’s immune system, which may help the CAR T cells work better.
Duarte, CaliforniaAges 4–25 - NCT06307548RecruitingPhase 1/Phase 2
Image-guided surgery and light therapy for colorectal cancer
This trial tests a special dye that helps surgeons see tumors more clearly during surgery, followed by a light therapy to destroy any remaining cancer cells. It is for people with advanced or returning colorectal cancer who are already scheduled for surgery.
Buffalo, New YorkAges 18 years+ - NCT07532525RecruitingPhase 1
Pomalidomide after CAR T for B-cell cancer
This trial tests whether the drug pomalidomide, given as a pill, can help people with B-cell leukemia or lymphoma who have recently received CAR T-cell therapy. The goal is to see if pomalidomide can keep the cancer from coming back, and it may be an option for those whose cancer is not growing but still needs management.
Ann Arbor, MichiganAges 18 years+ - NCT07721181Recruiting
STEP-UP: Higher radiation for recurrent rectal cancer
This trial tests giving a higher dose of radiation to people whose rectal cancer has come back in the pelvis after surgery and cannot be removed. It aims to see if more radiation can help control the tumor when surgery is not an option.
Maastricht, LimburgAges 18 years+ - NCT03238378Recruiting
Radiation boost plus warming for recurrent head and neck tumors
This trial tests a “salvage” treatment that combines targeted radiation (brachytherapy) with controlled body warming (hyperthermia) for head and neck cancer that has come back. It may help by better shrinking tumors while fitting the treatment to the tumor’s exact location.
ErlangenAges 18 years+ - NCT04288999RecruitingPhase 3
Surgery plus chemo versus chemo-radiation then surgery for recurrent rectal cancer
This study compares two treatment plans for locally recurrent rectal cancer: (1) surgery plus chemo, or (2) chemo plus radiation first, then surgery, followed by chemo. It aims to see which approach works better in controlling the cancer and helping patients recover.
ChibaAges 20–80 - NCT04695782RecruitingPhase 2
Proton radiation for recurrent rectal cancer in the pelvis
This trial studies “pencil beam” proton radiation for rectal cancer that has come back in the pelvis after you already had radiation. It aims to control the recurrence while trying to limit harm to nearby organs.
AarhusAges 18 years+ - NCT04376866RecruitingPhase 3
Immunotherapy for repeat nasopharyngeal cancer after it returns
This trial studies toripalimab (an immunotherapy that helps your immune system attack cancer) for nasopharyngeal cancer that has come back locally. It may help shrink or control the returning tumor and improve outcomes for people who meet the safety and lab requirements.
Nanning, GuangxiAges 18–65 - NCT05055635RecruitingPhase 2
Proton radiation for anal cancer that came back after prior treatment
This trial studies a focused type of proton radiation (“pencil beam”) to treat anal cancer that has returned after you previously had radiation. It may help by aiming treatment more precisely and giving another chance at cure when doctors think it can still be treated.
Aarhus N, AarhusAges 18 years+ - NCT03983226RecruitingPhase 2
Surgery plus niraparib for returning ovarian cancer
This trial tests whether adding niraparib (a pill treatment that targets cancer cell DNA repair) after surgery can help people with ovarian cancer that has come back. It focuses on “platinum-sensitive” cases and tries to remove all visible tumor when possible.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05553652Recruiting
A probiotic test for repeat bladder infections
This trial studies ASTARTE™, a probiotic, to see if it can reduce repeat urinary tract infections (UTIs). It may help people who get UTIs often by testing whether the supplement lowers how frequently they come back.
