You may join during pregnancy or up to 2 years after delivery, and you would share medical information and undergo follow-up visits.
Bethesda, MarylandAges 18–100 - NCT04529629Recruiting
Tests and tracks treatment for adrenal hormone tumor diseases
This trial studies how adrenal hormone tumor diseases should be diagnosed, treated, and followed over time. It may help people get more precise care and better prediction of outcomes, but it has specific health and medication requirements.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT03882840RecruitingPhase 1/Phase 2
T-like NK cell therapy for cancers with low MHC-I
This early-stage trial tests a lab-made immune cell treatment (T-like NK cells) for advanced cancers that have low or missing MHC-I on their cells. Because the treatment aims to “re-activate” the immune system against these cancers, you may be eligible if your cancer matches this feature and you meet safety requirements.
Guangzhou, GuangdongAges 18 years+ - NCT04604509RecruitingPhase 4
Smoking quit plan using counseling and nicotine-free medicines
This trial tests whether a quit program that combines counseling with medicines (nicotine replacement, varenicline, or bupropion) helps people stop or cut down smoking. It’s also delivered through telehealth, with repeated check-ins to see how well the plan works and whether it’s safe for you.
Houston, TexasAges 18 years+ - NCT04329065RecruitingPhase 2
Vaccine with targeted breast cancer drugs before surgery
This Phase 2 trial tests whether adding a cancer vaccine (with GM-CSF) to standard HER2-targeted chemotherapy before surgery improves treatment outcomes for HER2-positive breast cancer. If you join, you’ll receive planned medicine before surgery to treat the tumor, then continue with the study schedule.
Seattle, WashingtonAges 18 years+ - NCT04196413RecruitingPhase 1
CAR T cell treatment for a specific brainstem glioma mutation
This Phase 1 study tests a custom immune therapy called GD2 CAR T cells in children and adults with a specific type of diffuse midline glioma (DMG) that has the H3K27M mutation. The goal is to see if the treatment is safe and can help control the cancer.
Stanford, CaliforniaAges 2–60 - NCT04088422Recruiting
Blood test DNA study in mature B-cell lymphoma
This study looks at “cell-free DNA,” meaning tiny bits of DNA found in blood, in people with mature B-cell lymphoma. It may help doctors understand the disease better and how blood tests could be used to monitor it.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT04328298Recruiting
Register study of people in France eligible for CAR-T therapy
This study collects health data from people in France who received CAR-T treatment or are eligible to receive it. It helps doctors and researchers understand who can get CAR-T and how treatment is used in real life.
AmiensAges birth–99 years - NCT04613388Recruiting
Proton radiation registry study for adults with lymphoma
This study collects information about adults with lymphoma who need treatment that targets the chest/mediastinum. It focuses on how proton radiation may help protect the heart, lungs, and breast compared with the more common photon radiation.
HeidelbergAges 18 years+ - NCT04282031RecruitingPhase 1/Phase 2
BPI-1178 for advanced breast cancer or solid tumors
This early-phase study tests BPI-1178 in people with advanced (stage 4 or hard-to-treat) solid tumors, including HR+/HER2- breast cancer. It looks at how well the treatment works and how safe it is, especially after standard treatments have stopped working or aren’t an option.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT04295473Recruiting
Test of smaller-incision stomach surgery for gastric cancer
This trial studies a stomach cancer surgery done with fewer/smaller incisions (laparoscopic with reduced ports). It may help people with certain early-to-mid stage stomach cancers by comparing whether this approach is safe and effective for them.
Nanchong, SichuanAges 18–90 - NCT04218617RecruitingPhase 2
One vs two radiation treatments for spine metastases
This trial tests whether giving radiation to a spine metastasis in one dose works as well as giving it in two smaller doses. It aims to control tumors while keeping side effects and risk to the spinal cord low.
Cleveland, OhioAges 18 years+ - NCT03797482Recruiting
Tracking low oxygen around breast cancer surgery
This study measures low oxygen that can happen during the time around breast cancer surgery. It may help doctors understand why this happens and how to improve care around the operation.
Mumbai, MaharashtraAges 18 years+ - NCT04428671RecruitingPhase 1
Cemiplimab before and after surgery for high-risk skin cancer
This Phase 1 trial tests the drug cemiplimab given before and after surgery to reduce the chance that high-risk cutaneous squamous cell cancer comes back. You may be a candidate if your cancer is high-risk on pathology or imaging and is planned for surgical removal.
Atlanta, GeorgiaAges 18 years+ - NCT04219254RecruitingPhase 1/Phase 2
Testing BI-1206 with pembrolizumab for advanced solid cancers
This early-phase trial studies BI-1206 together with pembrolizumab to treat advanced solid tumors. It may be an option if your cancer has progressed after prior anti–PD-1/PD-L1 treatment (or, in some groups, if standard treatments aren’t suitable).
Los Angeles, CaliforniaAges 18 years+ - NCT04678583Recruiting
Surgery plan for RAS-mutant colon cancer liver metastases
This trial studies an approach to surgically removing liver metastases from colon (or rectal) cancer that has an RAS gene mutation (KRAS or NRAS). If you qualify, you would be evaluated for whether a “complete” (R0) liver operation is planned and technically possible, aiming to improve cancer control by how the liver is cut.
Mannheim, Baden-WurttembergAges 18 years+ - NCT04061239RecruitingPhase 2
New treatment options before stem cell transplant for higher-risk MDS/AML
This Phase 2 trial compares treatment approaches for people with higher-risk MDS or a specific type of AML before they get a stem cell transplant. The goal is to see which approach helps you get ready for transplant more safely and effectively.
LinzAges 18–75 - NCT05067283RecruitingPhase 1
Study of Calderasib for KRAS G12C advanced cancers
This trial tests a new drug, Calderasib, for people with advanced solid tumors that have a specific mutation called KRAS G12C. It may help if your cancer has not responded to previous treatments or if you have certain types of lung or colorectal cancer.
Tampa, FloridaAges 18 years+ - NCT04512846Recruiting
Radiation for large liver cancer, with or without chemo
This trial compares two treatment approaches for large hepatocellular carcinoma (HCC), a type of liver cancer: stereotactic body radiation therapy (SBRT) alone versus SBRT plus TACE, a catheter-based chemo treatment. It may help decide which approach works better for controlling the tumor when surgery isn’t a good option.
BeijingAges 30–80 - NCT03878849RecruitingPhase 2
Study drug 2X-121 for ovarian cancer that keeps coming back
This Phase 2 trial tests whether 2X-121 can shrink or control ovarian, fallopian tube, or primary peritoneal cancer that is resistant to platinum chemotherapy. It enrolls people who have had limited prior treatment and can provide a recent or stored tumor sample.
Oklahoma City, OklahomaAges 18 years+ - NCT04566380RecruitingPhase 2
Study for people already taking ONO-4538
This trial is for people who are already being treated with ONO-4538 (either alone or with other treatments) and can continue into an “extension/rollover” study. It checks how well ONO-4538 continues to work and is used safely over more time.
Kashiwa, ChibaAges 16 years+ - NCT04086290RecruitingPhase 1/Phase 2
Surgery plus targeted radiation for prostate cancer spread
This study looks at whether combining prostate surgery with a highly focused radiation treatment (SBRT) can control prostate cancer that has spread to a limited number of bones. It may help patients by treating the main tumor and the specific metastatic spots in a controlled way.
HerlevAges 18 years+ - NCT04478006Recruiting
