Study of surgery plan for advanced ovarian or peritoneal cancer
This trial looks at whether a specific treatment pathway that may include surgery helps people with advanced ovarian (or related) cancer. It mainly involves planning and undergoing a complex pelvic surgery, sometimes after chemotherapy, to improve outcomes.
BordeauxAges 70 years+ - NCT04286841Recruiting
Immunotherapy before lung surgery for early lung cancer
This trial looks at giving immunotherapy before surgery for certain early-stage lung cancers to help shrink the tumor and improve outcomes. It is mainly for people whose lung cancer can be removed by surgery and who don’t have specific gene changes like EGFR or ALK.

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 - NCT04287088Recruiting
MRI plus shared decisions to help diagnose prostate cancer
This study looks at using a special prostate MRI (bpMRI) along with a risk-based shared decision process to guide diagnosis. It may help patients and clinicians decide on next steps using MRI results and individual risk.
JyväskyläAges 18 years+ - NCT04289935Recruiting
Vacuum biopsy before surgery to check treatment response
This trial studies a special vacuum-assisted biopsy taken just before breast surgery to see how well pre-surgery (neoadjuvant) chemotherapy worked. It may help doctors understand whether patients truly had a complete or near-complete response on scans, which can guide next steps.
SalzburgAges 18 years+ - NCT04290663RecruitingPhase 3
Radioiodine decision after thyroid surgery for intermediate-risk cancer
This study compares two approaches after thyroid surgery: giving radioactive iodine right away versus deciding based on follow-up test results. It aims to see which approach better helps people with intermediate-risk differentiated thyroid cancer.
Pointe à Pitre, GuadeloupeAges 18 years+ - NCT04290000Recruiting
Share samples after CAR-T treatment at Montpellier hospital
This study collects and stores biological samples from people who have been treated with CAR-T cells at the University Hospital of Montpellier. Your samples can help researchers learn more about treatment effects and safety.
MontpellierAges 18 years+ - NCT04290806Recruiting
SAPHIR registry for advanced stomach and esophagus cancer
This registry collects information from people with stage IV (metastatic) stomach or esophagus cancers who are about to start their first medicines to control the disease. It may help researchers understand which treatments are used and how patients do over time.
Multiple LocationsAges 18 years+ - NCT04291755Recruiting
Stool bank for people receiving cancer immunotherapy
This study is building a “stool bank,” meaning they collect and store stool samples from people who are getting cancer immunotherapy. Researchers plan to analyze these samples to better understand cancer and treatment—your participation may help future research.
Fountain Valley, CaliforniaAges 18 years+ - NCT04291651Recruiting
Pancreatic Cyst Registry for Adults With Pancreatic Cysts
This registry study collects information from adults who have a pancreatic cyst (a fluid-filled sac in the pancreas). It may help doctors understand these cysts and how they change over time, which can improve future care.
San Francisco, CaliforniaAges 18 years+ - NCT04291378Recruiting
Proton versus standard radiation for early breast cancer
This trial compares two types of radiation—proton therapy and standard photon therapy—for early breast cancer after surgery. It’s mainly for people whose usual radiation plan would put a higher dose to the heart and/or lungs, aiming to reduce that exposure.
AalborgAges 18 years+ - NCT04293562RecruitingPhase 3
Testing targeted drugs plus chemo for newly diagnosed AML
This study compares standard chemotherapy to chemotherapy plus CPX-351 and/or gilteritinib in children and young adults newly diagnosed with AML. It aims to see whether adding these targeted treatments improves outcomes, especially for certain gene changes like FLT3.
Birmingham, AlabamaAges Up to 21 years - NCT04294927Recruiting
Tube removal first, then ovaries later for high-risk women
This study looks at whether removing the fallopian tubes first, and the ovaries later, is safe for women with certain inherited gene mutations that raise ovarian cancer risk. It may help you understand a prevention approach when you’re considered high risk and have finished having children.
Chicago, IllinoisAges 25–50 - NCT04295863RecruitingPhase 1
Test different dosing schedules for two immunotherapy drugs
This early trial compares how often two immune system medicines—nivolumab and pembrolizumab—are given for advanced or metastatic cancers. It aims to see which dosing interval is workable and safe for people needing treatment.
Chicago, IllinoisAges 18 years+ - NCT04299191RecruitingPhase 1/Phase 2
LAM561 for children with advanced brain or solid tumors
This Phase 1/2 study tests a medicine called LAM561 in children whose cancer is advanced and not responding to standard treatment. The goal is to see if the drug is safe and can shrink or control tumors in this setting.
Little Rock, ArkansasAges Up to 18 years - NCT04297020Recruiting
Checking brain health in breast cancer survivors
This study looks at differences in brain function in people who have had breast cancer, compared with certain people without that history. It’s testing how brain health changes after breast cancer and relates to mood, thinking, and daily functioning.
Los Angeles, CaliforniaAges 35–65 - NCT04297605RecruitingPhase 1
Pembrolizumab plus chemotherapy for advanced lung cancer
This Phase 1 study tests pembrolizumab (an immunotherapy) given together with a chemotherapy drug to treat non-small cell lung cancer that is locally advanced or has spread. It’s aimed at people who can handle treatment with an ECOG performance status of 2, including some with certain types of brain metastases.
Rochester, New YorkAges 18 years+ - NCT04299581RecruitingPhase 2
Freezing treatment plus immunotherapy for advanced bile-duct cancer
This Phase 2 trial tests whether freezing part of the liver tumor (cryoablation) combined with an immunotherapy drug called anti–PD-1 can shrink advanced bile-duct cancer that can’t be removed by surgery. It may help control the cancer after prior treatments have stopped working.
ShanghaiAges 18 years+ - NCT04299646RecruitingPhase 2
Stereotactic radiation for limited spread in kidney cancer
This trial tests whether targeted, high-precision radiation (stereotactic radiotherapy) can control a small number of growing kidney cancer metastases while you continue systemic treatment. It may help people who have “oligoprogressive” disease, where only 1–3 spots are getting worse.
AlbiAges 18 years+ - NCT04300556RecruitingPhase 1/Phase 2
Testing an antibody-drug for advanced certain cancers
This early-phase trial tests a treatment called MORAb-202, an antibody “delivery” drug, to see if it’s safe and can help shrink or control certain advanced cancers. It may help people whose tumors match the study’s specific cancer types and prior treatment history.

Prediction tool for choosing treatment in sarcoma care
This trial tests a way to use patient information to help doctors decide which treatment approach may fit best for people with certain bone or soft-tissue tumors. It may help improve selection and care planning, but it depends on whether your data can be used.
