Bethesda, MarylandAges 18–120 - NCT04239157RecruitingPhase 2
Canakinumab shot for lower-risk MDS and related blood disorders
This trial tests canakinumab, a medication that blocks inflammation, given as a skin (subcutaneous) injection. It is for adults with lower-risk myelodysplastic syndromes (MDS) or a related condition (chronic myelomonocytic leukemia or CCUS) to see if it can improve blood counts and reduce problems like anemia or transfusion needs.
Houston, TexasAges 18 years+ - NCT04240054RecruitingPhase 2
Study drugs before transplant for myeloma with kidney problems
This Phase 2 trial tests whether a combination of anti-myeloma medicines given before stem cell transplant works well and is safe for people with multiple myeloma who also have kidney problems. It may help control the myeloma and prepare you for the transplant.
Milwaukee, WisconsinAges 18 years+ - NCT04243720Recruiting
Study of immune resistance after immunotherapy
This trial studies why some solid cancers stop responding to immune-based drugs (like anti–PD-1/PD-L1) and what can be done next. You may be eligible if your cancer has progressed after immunotherapy and you can safely undergo a tumor needle biopsy.
Toronto, OntarioAges 18 years+ - NCT04242017RecruitingPhase 2/Phase 3
Longer hormone treatment plus salvage radiation versus shorter
This trial compares two schedules of hormone treatment (ADT) along with salvage radiation after prostate cancer surgery, to see which one controls cancer better over the long term. It may help people who have a rising PSA level after surgery but no spread found yet.
GhentAges Any age - NCT04243785RecruitingPhase 1
Testing BTX-A51 for hard-to-treat AML or high-risk MDS
This Phase 1 study tests BTX-A51 in adults with relapsed or refractory acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS). It’s designed to see if the treatment can be given safely and to learn how it works in people whose standard treatments have not helped or are no longer an option.
Duarte, CaliforniaAges 18 years+ - NCT04245683Recruiting
Testing non-surgical treatment for newly diagnosed rectal cancer
This study looks at whether it’s practical and safe to treat certain rectal cancers without surgery. You may be offered non-surgical (“neoadjuvant”) treatment and close follow-up to see how well it works in a rural setting.
Cooperstown, New YorkAges 18 years+ - NCT04249154RecruitingPhase 2
After prostate surgery, test radiation plus hormone shots
This trial studies whether giving a shorter-course radiation plan after prostate surgery, along with hormone shots (LHRH), can improve outcomes for people with higher-risk prostate cancer. You may be eligible if your PSA (a blood marker) is either still low but high-risk by pathology, or it has started to rise again after surgery.
Montreal, QuebecAges 18 years+ - NCT04253015Recruiting
Safety registry for people with high-risk neuroblastoma on dinutuximab beta
This study is a long-term safety and follow-up registry. It tracks how dinutuximab beta is doing in real-world patients with high-risk neuroblastoma over time.
Vienna, State of ViennaAges 1–18 - NCT04254419RecruitingPhase 1
Natural killer cell injections in the brain tumor area
This early-phase trial tests injections of lab-grown immune cells directly into (or near) a brain tumor. It aims to see if the treatment is safe and can help control recurrent, progressive, or resistant CNS tumors.
Columbus, OhioAges 1–39 - NCT04256018RecruitingPhase 2
Mogamulizumab with low-dose skin radiation for lymphoma skin disease
This Phase 2 study tests mogamulizumab together with low-dose total skin electron beam radiation to treat mycosis fungoides or Sézary syndrome, two types of skin lymphoma. It may help shrink skin disease and control symptoms by combining an immune-targeting medicine with skin-focused radiation.
Stanford, CaliforniaAges 18 years+ - NCT04256317RecruitingPhase 2/Phase 3
Azacitidine pills with or without venetoclax for certain blood cancers
This study tests whether a pill form of azacitidine (ASTX030) helps people with myelodysplastic syndromes (MDS), CMML, or AML. Some groups may also receive venetoclax; the goal is better blood cancer control for people who aren’t good candidates for intensive chemotherapy.
Los Angeles, CaliforniaAges 18 years+ - NCT04258449Recruiting
Testing a new uterine sampling tool during surgery
This trial tests a new device that takes small samples from the uterus during surgery for suspected or confirmed upper reproductive tract cancer. It may help doctors collect better tissue samples safely while you are already having surgery for tumor removal.
Montreal, QuebecAges 18 years+ - NCT04258280Recruiting
Genetic counseling support for BRCA-positive mothers
This trial looks at ways to improve genetic counseling for mothers (or primary caregivers) of teens and young adults who are BRCA-positive. It may help you understand genetic results and what they mean for your family, using better counseling support.
Washington D.C., District of ColumbiaAges 18 years+ - NCT04260022RecruitingPhase 1
Drug study for hard-to-treat CML or Ph+ ALL
This Phase 1 study tests HQP1351 for people with CML or Ph+ ALL that has not responded well to standard targeted pills (TKIs), or those who could not tolerate them. It’s designed to see whether the treatment can work and how safe it is for this difficult-to-treat group.
Birmingham, AlabamaAges 18 years+ - NCT04261829Recruiting
Full method for breast reconstruction after mastectomy
This trial tests a “full breast reconstruction” approach for people who are planning or have had a breast removal (mastectomy). It may help improve how reconstruction is done and whether you can use the external expansion device as part of the process.
Maastricht, LimburgAges 18 years+ - NCT04261192Recruiting
Grow lab models of head and neck cancer to test treatments
This study collects tissue from people with newly diagnosed head and neck squamous cell cancer and grows “mini tumor models” in the lab. The goal is to see how these models respond to new therapies, which may help guide more effective treatment choices in the future.
CaenAges 18 years+ - NCT04261244RecruitingPhase 3
Neoadjuvant radiation study for one-sided breast cancer
This Phase 3 study tests a specific plan that combines chemotherapy (and sometimes targeted medicines) with radiation before surgery for one breast. It may help shrink breast cancer and improve treatment timing, based on how well tumors respond.
AhausAges 18 years+ - NCT04262830Recruiting
Heart scans to predict future heart failure after chemotherapy
This trial uses detailed heart imaging (a special MRI scan) to see how chemotherapy may have affected your heart and to predict who could develop heart failure later. If you qualify, it may help your care team better monitor your heart health over time.
San Diego, CaliforniaAges 13–39 - NCT04265430RecruitingPhase 4
MRI scans to predict normal-tissue side effects after treatment
This trial uses repeated MRI scans to better predict which patients may develop painful jaw and mouth tissue problems after radiation and/or certain bone or blood-vessel medicines. It may help clinicians spot problems earlier and tailor follow-up care.
Houston, TexasAges 18 years+ - NCT04263857Recruiting
Register of Stem Cell Transplant Patients
This study creates a record of people who are eligible to receive a stem cell (blood-forming cell) transplant. It helps researchers learn about transplant patients and outcomes over time.
MunichAges 18 years+ - NCT04263298RecruitingPhase 3
Fulvestrant or capecitabine after chemo for metastatic breast cancer
This Phase 3 trial compares two medicines—fulvestrant versus capecitabine—as “maintenance” treatment after your first chemo helps control metastatic breast cancer. It aims to see which one helps people live longer with better disease control.
Guangzhou, GuangdongAges 18–75 - NCT04263935Recruiting
Lymphoma gene changes and what they mean for outcomes
This study looks at lymphoma’s DNA “driver gene” changes and how they relate to symptoms, lab findings, and prognosis (how the disease is expected to do over time). It may help doctors better predict outcomes for people with lymphoma based on their tumor biology.
Zhengzhou, HenanAges Any age - NCT04268121RecruitingPhase 2
Neoadjuvant chemotherapy before surgery for certain digestive neuroendocrine cancers
This study looks at whether chemotherapy given before surgery improves how long patients live without the cancer coming back. It’s aimed at people with localized, poorly differentiated digestive neuroendocrine carcinoma with a higher growth rate marker.
