This study collects biological samples (like blood or other specimens) from people with rare neurological conditions that may involve the immune system. Your samples may help researchers better understand these diseases.
ToulouseAges 6–99 - NCT04698785RecruitingPhase 2
Regorafenib to help prevent cancer return after treatment
This Phase 2 study tests whether regorafenib, given after your main treatments, can help keep high-grade bone sarcoma from coming back or progressing. It checks safety and whether this “maintenance” approach works better than best supportive care alone.
BesançonAges 12 years+ - NCT04699292Recruiting
Registry study for local treatment in soft tissue sarcoma
This registry collects coded information about adults with a specific soft tissue sarcoma (MLS) to better understand how local treatments help. If you qualify, you don’t necessarily receive a new drug in this study—your data is used to improve future care.
AmsterdamAges 18 years+ - NCT04699773Recruiting
Laser treatment then focused radiation for new brain gliomas
This trial studies a two-step treatment for newly diagnosed high-grade glioma: first laser treatment (LITT) to target the tumor, followed by a shorter, more focused course of radiation. It may help shrink or control the tumor while limiting treatment time.
Baltimore, MarylandAges 18 years+ - NCT04700332RecruitingPhase 2
Test of PyL PET/CT for high-risk or returning prostate cancer
This Phase 2 study checks how well a scan called PyL PET/CT can help find prostate cancer that is high-risk or has come back by blood test. The goal is to improve how doctors detect spread and guide the next treatment steps.
Irvine, CaliforniaAges 18 years+ - NCT04701645RecruitingPhase 1
Microdevice study for advanced ovarian or related cancers
This Phase 1 study tests a tiny implanted device placed in the abdomen to help evaluate or treat advanced ovarian, fallopian tube, or peritoneal cancer. If you qualify, you’d also have additional tests and surgery as part of your usual care plan.
Boston, MassachusettsAges 18 years+ - NCT04701476RecruitingPhase 2
Pembrolizumab for advanced colorectal or lung cancer
This study tests pembrolizumab (an immune system medicine) with another treatment (TATE) in people with advanced colorectal or lung cancer that is not driven by certain gene changes. It may help shrink tumors after standard chemotherapy has stopped working.
Orange, CaliforniaAges 18 years+ - NCT04703101RecruitingPhase 1
Short radiation plus chemo for stage II–III rectal cancer
This trial tests a short course of radiation therapy combined with chemotherapy for people with stage II or III rectal cancer. It’s designed to see whether this approach is safe and effective before or around cancer surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT04702321Recruiting
Study genetic risks for childhood cancer complications in Switzerland
This study looks at genetic factors to understand why some children who had cancer develop later complications. It uses stored samples and information from a Swiss biobank to help researchers identify higher-risk children.
GenevaAges Up to 21 years - NCT04701853Recruiting
Exercise training after permanent stoma surgery
This trial looks at a specific exercise program after planned surgery to create a permanent stoma (an opening for stool). The goal is to see whether the training helps people recover and function better after surgery.
GothenburgAges Any age - NCT04703244Recruiting
Testing patient tumor samples to create research models in breast cancer
This study collects tumor-related samples from people with invasive breast cancer who are having surgery after treatment before surgery. Researchers use your samples to create lab models (called PDX and organoids) to help study breast cancer and find better future treatments.
Rochester, MinnesotaAges 18 years+ - NCT04702581RecruitingPhase 3
Delayed radiation versus usual timing for certain brain tumors
This trial studies whether delaying radiation therapy helps people with a slow-growing brain tumor called low-grade oligodendroglioma that has specific genetic markers. It compares delayed radiation to standard timing to see which approach controls the tumor with acceptable side effects and quality of life.
AmiensAges 18 years+ - NCT04704323RecruitingPhase 1
CAP-100 drug study for hard-to-treat CLL after prior treatments
This early-phase (Phase 1) study tests CAP-100 in adults with CLL or SLL that has come back or did not respond to at least two previous treatments. The goal is to see how the drug works and whether it is safe enough to keep studying.
Boston, MassachusettsAges 18 years+ - NCT04706754Recruiting
Study of lung cancer information across Canada
This observational study collects information from adults with lung cancer to better understand the disease over time. If you join, it helps researchers learn from real-world experiences rather than testing a new drug.
Brampton, OntarioAges 18 years+ - NCT04706481Recruiting
Use of stored, de-identified samples for research
This trial is for people who already agreed to let researchers use their stored biological samples and medical information that has been removed of personal identifiers. It may help future studies by allowing researchers to analyze existing samples without using new samples from you.
Hong KongAges Any age - NCT04706910RecruitingPhase 3
PET scan study to optimize imaging in several diseases
This trial improves a special PET scan (a type of brain/body imaging) using 18F-DOPA, to better show how certain conditions behave in the body. If you or your child may have one of the listed conditions, the study may help your doctors get clearer scan results.
Edmonton, AlbertaAges Any age - NCT04708054RecruitingPhase 2/Phase 3
Venetoclax with busulfan chemo for high-risk AML or MDS
This study tests whether adding venetoclax to a specific busulfan-based chemotherapy plan improves outcomes for people with high-risk AML or MDS. It mainly targets patients whose leukemia/marrow disease still has high-risk features or measurable disease after initial treatment.
Houston, TexasAges 18–70 - NCT04708171Recruiting
Compare awake, asleep, or no mapping during brain tumor surgery
This study looks at whether surgeons get better safety and control during glioblastoma removal by using awake testing, asleep testing, or no mapping. Mapping helps identify brain areas involved in movement, speech, or vision to lower the risk of serious side effects.
San Francisco, CaliforniaAges 18–90 - NCT04710797Recruiting
Lymph node surgery for early-stage ovarian cancer
This trial studies whether removing (dissecting) lymph nodes during surgery can improve care for people with early-stage ovarian cancer that still needs chemotherapy. You may be eligible if you have certain ovarian cancer types and your scans and surgery do not show clearly suspicious lymph nodes.
Guangzhou, GuangdongAges 18–70 - NCT04710758Recruiting
Keyhole surgery for advanced stomach cancer
This trial looks at laparoscopic (keyhole) total stomach removal for people with advanced stomach cancer in the upper or middle part of the stomach. It aims to see whether this operation approach is safe and useful based on your tumor stage and overall health.
