Philadelphia, PennsylvaniaAges 18 years+ - NCT06641791RecruitingPhase 3
Comparing two radiation approaches for advanced head and neck cancer
This trial compares two types of radiation therapy to relieve symptoms from advanced head and neck cancer that cannot be cured. One is a shorter, more precise treatment (SBRT), and the other is standard radiation. The goal is to see which better improves quality of life and reduces side effects.
Calgary, AlbertaAges 18 years+ - NCT04146298RecruitingPhase 1/Phase 2
KRAS-mutant pancreatic cancer T-cell therapy for some people
This Phase 1/2 study tests a lab-made immune cell (T-cell) treatment that targets a specific KRAS mutation (G12V) found in some pancreatic cancers. It may help shrink tumors or control cancer growth after standard treatment, and it mainly focuses on safety and early effectiveness.
ShanghaiAges 18–75 - NCT04342546Recruiting
Radiation skin side-effect test after mastectomy with implant
This trial looks at a test meant to predict how likely you are to develop side effects from radiation to the chest wall after mastectomy. It is designed for people getting immediate breast reconstruction using an implant, so treatment planning may be safer and more personalized.
DijonAges 18 years+ - NCT04457895Recruiting
Yoga and physical therapy program for hormone therapy breast cancer pain
This trial studies whether a combined physical therapy, yoga, and patient education program can reduce pain in people with non-metastatic breast cancer who are taking hormone therapy. It may help with pain and day-to-day comfort while you continue hormone treatment.
Libourne, AquitaineAges 18–99 - NCT04469296Recruiting
Diet changes before surgery for hormone-receptor breast cancer
This trial tests whether changing your diet before your breast surgery can help people with early, hormone-receptor (ER/PR+) breast cancer. It focuses on patients who have not started treatment yet and want to keep surgery as the main treatment.
Montpellier, HeraultAges 18–80 - NCT04495790Recruiting
Cancer patient study to track health outcomes
This is an observational study that follows people with cancer to better understand outcomes over time. You may be asked to complete questionnaires and share information from your visits (in person or by video only if you meet their rules).
Seattle, WashingtonAges Any age - NCT04523857RecruitingPhase 2
Abemaciclib and hydroxychloroquine after breast cancer relapse risk
This Phase 2 trial tests whether abemaciclib plus hydroxychloroquine can kill tiny “leftover” cancer cells in the bone marrow after standard breast cancer treatment. It may help lower the chance of cancer coming back by targeting minimal residual disease.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04636710Recruiting
Treatment approach study for stage III inflammatory breast cancer
This study looks at how to best plan local treatments (like surgery and/or radiation) for people with stage III inflammatory breast cancer. It may help doctors refine care plans for this aggressive subtype by studying how patients are treated and what outcomes they have.
Boston, MassachusettsAges 18 years+ - NCT04678648RecruitingPhase 1
Testing RSC-1255 in advanced cancers with RAS changes
This early study (Phase 1) tests a new drug, RSC-1255, in people with advanced or metastatic cancers that have RAS mutations. It’s mainly focused on whether the treatment can be given safely and at what dose, and to see if it may shrink tumors.
Los Angeles, CaliforniaAges 18 years+ - NCT04698252RecruitingPhase 2
Local treatment for ER/PR-positive limited spread breast cancer
This Phase 2 study tests whether treating a small number of metastatic spots with a local approach (like targeted radiation, surgery, or ablation) can help people with ER/PR-positive breast cancer. It aims to help when the cancer has spread only to a few areas and has not significantly worsened after initial whole-body treatment.
São Paulo, São PauloAges 18 years+ - NCT04852887RecruitingPhase 3
Testing shorter breast radiation after low-risk hormone breast cancer
This Phase 3 trial studies whether “less intense” radiation can work as well as standard radiation for certain early-stage hormone receptor–positive, HER2-negative breast cancers that have a low Oncotype DX score. It may help reduce treatment burden while keeping cancer control strong.
Birmingham, AlabamaAges 50–70 - NCT05035836RecruitingPhase 2
Test drug after early HER2-positive breast cancer surgery
This trial tests zanidatamab, a type of targeted antibody treatment, in people with early-stage HER2-positive breast cancer to see how well it works and how safe it is. Because it’s a single-arm pilot study, everyone in the study gets the drug, and you’ll likely be asked to undergo standard surgery if appropriate.
Houston, TexasAges 18 years+ - NCT05056350Recruiting
Coaching to help you return to work after breast cancer
This study tests whether a tailored coaching program can help people with non-metastatic breast cancer return to work in a way that fits their physical and emotional needs. It’s for people who have finished most cancer treatments and are dealing with job-related difficulties.
