Cleveland, OhioAges 18–100 - NCT05057845RecruitingPhase 2
Freezing treatment plus immunotherapy and a pill for liver cancer
This trial tests whether freezing (cryoablation) combined with tislelizumab and lenvatinib can help shrink advanced liver cancer and improve outcomes after earlier treatments stopped working or caused side effects. It may be an option if your cancer can’t be removed with surgery and you’ve already tried one prior systemic (whole-body) treatment.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT04750122RecruitingPhase 1/Phase 2
Drug-screening guided treatment before surgery for HER2 breast cancer
This trial tests a treatment plan that is chosen using drug-testing in a lab (to see which medicines may work best) before surgery. It is for people with early-stage HER2-positive breast cancer, aiming to improve outcomes by guiding the right treatment early.
Beijing, Beijing MunicipalityAges 18–75 - NCT05244278Recruiting
AI tool that helps find and classify colon polyps during colonoscopy
This trial tests an artificial-intelligence (AI) software tool that helps doctors spot and categorize polyps in real time during a colonoscopy. It may help improve how accurately and quickly polyps are detected during routine and medical colon exams.
Montreal, QuebecAges 45–89 - NCT05013086RecruitingEarly Phase 1
Study of a targeted radioactive drug for αVβ3-positive tumors
This early-phase study tests whether a targeted radioactive medicine (177Lu-AB-3PRGD2) can shrink or control tumors that strongly match a specific target seen on special scans. It may help people whose current standard treatments are not working or are no longer working.
Beijing, Beijing MunicipalityAges 18–80 - NCT05190094RecruitingPhase 2
Test blood-based laser scan to guide first-line breast cancer treatment
This Phase 2 study uses a specialized laser test on a blood sample to predict how well palbociclib plus letrozole or anastrozole will work. It’s for certain postmenopausal women with HER2-negative, hormone-receptor positive, advanced (stage IIIb/IV) breast cancer.
BlidaAges 18 years+ - NCT05142150Recruiting
Care and expectations study for advanced gynecologic cancer
This trial looks at what patients with advanced gynecologic cancer expect from care, and how well their care needs are being met. It uses questionnaires to learn what support is most helpful, especially near the end of life.
OsloAges 18 years+ - NCT04891198RecruitingPhase 2
Envafolimumab for advanced cancers after other treatments
This trial tests envafolimumab, an immune therapy given alone, in people with advanced solid tumors that can’t be removed by surgery or have spread. It’s for patients whose cancer has grown despite (or they couldn’t tolerate) standard treatment, and it aims to find whether this drug can shrink tumors or slow growth.
BeijingAges 18 years+ - NCT04731610Recruiting
Radiation after thymoma surgery versus watchful waiting
This trial compares two approaches after complete surgical removal of stage IIb or III thymoma: targeted radiation (conformal post-operative radiotherapy) or no further treatment right away (surveillance). It aims to see whether adding radiation lowers the risk of the cancer coming back without causing unacceptable side effects.
CaenAges 18–75 - NCT05000892RecruitingPhase 2
Immunotherapy plus chemotherapy before surgery for salivary cancer
This trial studies giving an immunotherapy drug (sintilimab) plus two chemotherapy medicines before surgery to shrink salivary gland cancer. The goal is to improve how well the cancer responds and is controlled, while still aiming for a cure through surgery.
Guangzhou, GuangdongAges 18–80 - NCT04751409RecruitingPhase 2
Less versus more follow-up after sarcoma surgery
This trial compares two schedules of post-treatment check-ups to see which one better supports patient quality of life. You’d fill out surveys for up to two years to measure how you feel over time.
Houston, TexasAges 18 years+ - NCT04906434RecruitingPhase 1
Study of ABSK-011 for advanced solid tumors
This early-phase study tests how safe ABSK-011 is, what side effects it causes, and how the body processes the drug. It may help certain patients with advanced solid cancers (including some liver cancer cases) whose tumors have specific test results.
Phoenix, ArizonaAges 18–75 - NCT05124964Recruiting
Quality of life study for newly diagnosed brain germ cell tumors
This study looks at how life quality changes in children and young adults after a new diagnosis of a brain germ cell tumor. It may help doctors understand which supports improve day-to-day well-being.
BeijingAges 3–30 - NCT04920474Recruiting
Share blood and transplant samples for future research
This study builds a library of transplant and related medical samples to help scientists learn how to improve cell therapies and care for marrow injury. You may be included because you are a donor, receive a transplant or cell therapy, or are treated for marrow toxic injury at participating centers.
