This study checks how well your heart works long after breast cancer treatment. If you joined the earlier de BLOC-I study, you may be invited for follow-up to understand long-term heart effects.
GroningenAges Any age - NCT05851014RecruitingPhase 3
GB491 plus letrozole for HR+ HER2- advanced breast cancer
This Phase 3 study tests whether GB491 used together with letrozole works better for hormone receptor–positive and HER2-negative advanced breast cancer. You may be eligible if you have not had certain prior cancer treatments and your health tests are within safe limits.
Bengbu, AnhuiAges 18–75 - NCT05851534Recruiting
Pre-surgery risk reduction for pancreatic surgery
This study helps people going for planned pancreatic cancer surgery (with or without chemo beforehand) by focusing on controllable risk factors before the operation. The goal is to improve safety and outcomes after surgery.
's-HertogenboschAges 18 years+ - NCT05851677Recruiting
Study of disitamab vedotin for breast cancer
This trial studies disitamab vedotin (also called RC48-ADC) in people with breast cancer. It is mainly for patients who have already used this specific drug, to see how well it works as part of the study.
ShanghaiAges Any age - NCT05852717RecruitingPhase 2
Epcoritamab plus GDP chemotherapy for relapsed large B-cell lymphoma
This Phase 2 study tests epcoritamab combined with GDP chemotherapy to treat adults whose large B-cell lymphoma has come back or did not respond to prior treatment. It aims to improve how safely and effectively the disease can be controlled after standard chemotherapy.
Indianapolis, IndianaAges 18 years+ - NCT05852990RecruitingPhase 3
Gut help to prevent diarrhea from EGFR-targeted lung cancer drugs
This Phase 3 trial tests whether adding glutamine plus L. reuteri can help prevent severe diarrhea caused by EGFR-targeted treatments in people with advanced non-small cell lung cancer. If it works, it could make treatment easier to tolerate and help you stay on the planned therapy.
Mexico City, Mexico CityAges 18–80 - NCT05853094Recruiting
Testing different ways to create a stoma after rectal cancer surgery
This trial looks at how different stoma (opening in the belly) approaches affect recovery after curative rectal cancer surgery. It may help doctors choose the safest, most comfortable option for bowel function and healing after surgery.
ShanghaiAges 18–80 - NCT05853965RecruitingPhase 1/Phase 2
Study of belantamab plus venetoclax for relapsed myeloma
This Phase 1/2 trial tests whether combining belantamab mafodotin with venetoclax can treat multiple myeloma that has come back or did not respond (relapsed/refractory). It focuses on a specific myeloma subtype with a t(11;14) genetic marker, aiming to reduce the cancer in people who have already had several treatments.
Hamburg, HamAges 18 years+ - NCT05853783Recruiting
Testing a mouth test on biopsy samples from abnormal lesions
This trial looks at archived (saved) mouth biopsy samples to see how well the STRATICYTE™ test can identify potentially dangerous “pre-cancer-like” changes. It may help doctors screen or better understand which abnormal areas in the mouth later turn into oral cancer.
Birmingham, AlabamaAges 18 years+ - NCT05854368Recruiting
Blood tests to detect early stomach changes and cancer
This study looks for a blood “signature” that can spot early, risky stomach changes (before cancer) and stomach cancer. It may help clinicians diagnose earlier and decide who needs closer follow-up.
Boulogne-BillancourtAges 18 years+ - NCT05854563Recruiting
Study using collected cough samples to learn about lung disease
This trial looks at “cough capture” samples to better understand what is happening in the lungs. You might be eligible if you’re having a bronchoscopy for medical reasons and don’t already have lung cancer.
The Bronx, New YorkAges 21 years+ - NCT05854823Recruiting
Reduced radiation after surgery for advanced head and neck cancer
This trial looks at whether giving less (de-escalated) radiation after surgery is as effective and safer for people with locally advanced head and neck squamous cell carcinoma who had a strong response to treatment before surgery. If you had no remaining cancer or only very small amounts of cancer left in the surgical specimen, this approach may help reduce side effects while keeping control of the disease.
Zhuhai, GuangdongAges 18–70 - NCT05854849RecruitingPhase 3
Testing three-drug therapy versus cisplatin for recurrent NPC
This trial studies whether gemcitabine plus camrelizumab plus apatinib works better than cisplatin alone for people with recurrent or metastatic non-keratinizing nasopharyngeal cancer. It’s meant for people who haven’t had prior whole-body (systemic) treatment for the returning/spreading cancer.
Guangzhou, GuangdongAges 18–75 - NCT05855200RecruitingPhase 3
