St Louis, MissouriAges 18–90 - NCT04513639RecruitingPhase 2/Phase 3
Checking treatment for multiple myeloma after MRD becomes negative
This study looks at whether people with newly diagnosed multiple myeloma can safely continue or adjust treatment after they reach “MRD-negative,” meaning very low signs of disease in the bone marrow. It may help reduce the chance of relapse while avoiding unnecessary treatment for some patients.
ÅlesundAges 18–75 - NCT04513028Recruiting
Beta-glucan with immunotherapy for melanoma immune response
This study tests whether taking beta-glucan alongside pembrolizumab changes how your immune system responds in people with stage III–IV melanoma. It may help researchers understand whether beta-glucan improves immunotherapy activity after cancer has been controlled.
Louisville, KentuckyAges 18 years+ - NCT04513977Recruiting
Geriatric support clinic for newly diagnosed older cancer patients
This trial tests whether a geriatric (older-adult-focused) support clinic can help older adults with newly diagnosed early or locally advanced cancer before and during treatment. You may be offered extra support alongside planned cancer care, such as radiation or curative chemotherapy.
SingaporeAges 65 years+ - NCT04515459RecruitingPhase 2
Pre-surgery exercise and care program for limb sarcoma
This Phase 2 trial tests a “prehabilitation” program done before surgery to help people with arm or leg (limb) sarcoma be better prepared for their operation. It may help improve how well patients tolerate treatment and recover by planning supportive care around the weeks before surgery.
ToulouseAges 16 years+ - NCT04515836RecruitingPhase 2
Olaparib for HRD malignant mesothelioma after platinum chemotherapy
This trial tests whether olaparib (a cancer medicine) can help control malignant mesothelioma that has specific DNA changes. You must have already had platinum chemotherapy and your cancer must be “platinum-sensitive,” plus your tumor (or family/genetic cells) must show certain gene problems.
Chicago, IllinoisAges 18 years+ - NCT04516447RecruitingPhase 1
Testing a new drug for advanced ovarian cancer
This Phase 1 trial studies how well and how safely azenosertib (ZN-c3) works in people with advanced ovarian, fallopian tube, or peritoneal cancer. It may help by offering a new treatment option for cancers that don’t respond well to platinum chemotherapy (platinum-resistant).
Aurora, ColoradoAges 18 years+ - NCT04519151RecruitingPhase 2
Pembrolizumab plus lenvatinib for ovarian cancer that returned
This Phase 2 trial tests whether pembrolizumab plus lenvatinib can shrink ovarian cancer that has come back after platinum chemotherapy. You may be eligible if your cancer returned after a certain “time off” from prior treatment and you meet key health and safety requirements.
Ramat GanAges 18 years+ - NCT04516681RecruitingPhase 3
Ascorbic acid plus immunotherapy for spread colorectal cancer
This trial tests whether intravenous vitamin C (ascorbic acid) combined with an immune treatment (adebrelimab) can slow or shrink metastatic colorectal cancer that can’t be removed with surgery. It focuses on tumors that strongly show a specific marker called GLUT3, and aims to see if the combination works better than standard approaches.
Shanhai, Shanghai MunicipalityAges 18–75 - NCT04516720Recruiting
Build a database of brain and spinal cord tumor cases
This study builds a large medical database of people with primary brain or spinal cord tumors treated at the Montpellier Cancer Institute. It may help researchers understand patterns of care and outcomes, which can guide future research and treatment decisions.
Montpellier, HeraultAges 18 years+ - NCT04519905Recruiting
Testing two ways of radiation in older esophagus cancer patients
This study compares a planned radiation approach given at the same time as other treatment for older adults with esophageal squamous cell carcinoma. It may help find a safer and more effective radiation schedule for people who are fit enough for treatment.
Nanjing, JiangsuAges 76 years+ - NCT04520074RecruitingPhase 3
Chemo after surgery for BRCA1/2 wild-type ovarian cancer
This Phase 3 trial studies a three-step “extra” chemotherapy plan after surgery for people with certain advanced ovarian, fallopian-tube, or primary peritoneal cancers. The goal is to improve outcomes by lowering the chance the cancer comes back.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04520672Recruiting
Blood tests that look for circulating tumor cells in cancer
This study uses blood samples to look for tiny pieces of cancer cells called circulating tumor cells. Your results may help researchers understand how cancer cells spread and how cancer could be monitored over time.
BaselAges 18 years+ - NCT04520932Recruiting
Radiofrequency treatment for small nonfunctioning pancreatic tumors
This trial tests whether heating (radiofrequency) treatment guided by a special ultrasound scope can control small pancreatic neuroendocrine tumors. It may help patients whose tumors are very small and do not release hormones.
MarseilleAges 18–80 - NCT04523688RecruitingPhase 2
Dendritic cell vaccine made from your own tumor cells
This Phase 2 study tests a personalized glioblastoma vaccine made from your own immune cells (collected by apheresis) and your own tumor material. It’s meant to help your immune system recognize and attack the cancer after standard chemotherapy and radiation.
Meldola, FCAges 18 years+ - NCT04522687Recruiting
