BellinzonaAges 18 years+ - NCT04553770RecruitingPhase 2
Trastuzumab deruxtecan with or without anastrozole for early breast cancer
This Phase 2 study tests whether trastuzumab deruxtecan alone or combined with anastrozole can control early-stage breast cancer that is HER2-low and hormone-receptor positive. It aims to improve outcomes after initial surgical treatment by targeting cancer cells that may have low levels of HER2.
Fullerton, CaliforniaAges 18 years+ - NCT04585490RecruitingPhase 3
Testing a personalized add-on treatment after stage III lung cancer
This phase 3 trial tests whether tailoring the next (add-on) treatments can improve outcomes after standard chemoradiation and immunotherapy for stage III, unresectable (not operable) non-small cell lung cancer. It specifically looks at giving durvalumab plus an additional drug (tremelimumab) and possibly other consolidation chemotherapy based on a personalized plan.
Stanford, CaliforniaAges 18 years+ - NCT04616300Recruiting
Exercise program to support brain function during breast cancer chemo

Toronto, OntarioAges 18–65 - 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+ - NCT04771520RecruitingPhase 2
Avapritinib for tumors with specific KIT or PDGFRA changes
This Phase 2 trial studies avapritinib, a targeted medicine, for people whose cancer has specific KIT or PDGFRA genetic changes. It may help shrink or slow growth of certain advanced cancers, including some brain tumors, when standard treatments have not worked or for specific glioblastoma cases.
Houston, TexasAges 18 years+ - NCT04789681RecruitingPhase 2
Canakinumab to prevent lung cancer from persistent lung nodules
This trial tests canakinumab to lower the risk of lung cancer growing from persistent lung nodules seen on CT scans. It may help people at higher risk who have either never had lung cancer or had early lung cancer treated in the past.
Houston, TexasAges 18 years+ - NCT04841148RecruitingPhase 2
Avelumab or hydroxychloroquine to target hidden breast cancer
This Phase 2 trial tests whether adding different medicines—either avelumab or hydroxychloroquine, with or without palbociclib—can eliminate dormant “leftover” breast cancer cells. It’s meant for people with hormone-receptor–positive breast cancer who have no visible cancer now, but still have detectable dormant cells in the bone marrow.
Washington D.C., District of ColumbiaAges 18 years+ - NCT04886531RecruitingPhase 2
Pre-surgery neratinib plus hormone therapy with trastuzumab
This study tests whether a pre-surgery treatment plan that adds neratinib to hormone therapy and trastuzumab can shrink HER2-positive, ER-positive breast cancer before surgery. It may help patients by improving how much cancer is eliminated at the time of surgery.
Chicago, IllinoisAges 18 years+ - NCT04891068RecruitingPhase 2
Pre-surgery low-dose azacitidine for high-risk early breast cancer
This trial studies whether giving a low dose of azacitidine before surgery can shrink or control high-risk early breast cancer. It’s meant for adults whose cancer has not yet spread to distant organs.
Chicago, IllinoisAges 18 years+ - NCT04916990Recruiting
Care program for rural adults with several lung and head cancers
This study looks at how to improve care for adults with certain cancers who live in rural areas and may face access problems. It mainly focuses on people receiving cancer treatment at specific Colorado-area hospitals, and who are uninsured or underinsured.
Aurora, ColoradoAges 18–99 - NCT07137416RecruitingPhase 1
Testing a new combination of cancer drugs for HER2-positive tumors and breast cancer
This trial tests the safety of combining two drugs, CX-5461 (Pidnarulex) and Trastuzumab Deruxtecan (T-DXd), in people with HER2-positive solid tumors or certain types of breast cancer. If you have advanced cancer that hasn't responded to other treatments, this study may be an option.
Boston, MassachusettsAges 18 years+ - NCT04991025RecruitingPhase 2
Certolizumab added to chemo and nivolumab for operable lung cancer
This Phase 2 study tests whether adding certolizumab (an immune-targeting medicine) to standard chemo plus nivolumab can improve outcomes in people with certain operable non-small cell lung cancers. The goal is to see if this combination works better than standard treatment before surgery.
Basking Ridge, New JerseyAges 18 years+ - NCT04993014RecruitingPhase 2
De-escalating treatment after HER2-positive breast cancer responds
This study looks at whether some people with HER2-positive breast cancer can safely receive less (de-escalated) treatment after they finish chemotherapy plus HER2-targeted drugs before surgery. It specifically focuses on people whose cancer shows a complete response on the surgery pathology report.
São PauloAges 18 years+ - NCT04997096Recruiting
Exercise during chemo to prevent weakness from low movement
This study tests whether a structured exercise program during chemotherapy can help prevent physical decline (“immobility,” like getting weaker or moving less) in people with certain ovarian or endometrial cancers. If you’re eligible, you may be guided to exercise while receiving standard chemo, and you’ll have blood tests to track changes.
Boston, MassachusettsAges 18 years+ - NCT05010109Recruiting
Testing heart safety and fitness during lung cancer chemoradiation
This study looks at how lung cancer treatment affects the heart and whether a “walking test” and blood tests can track heart fitness and injury. It may help by improving how cancer therapy is planned and monitored for heart safety.
Houston, TexasAges 18 years+ - NCT05020860RecruitingPhase 2
Study how early breast cancer responds on imaging and under a microscope
This Phase 2 study looks at how well early breast cancer shrinks with treatment and how that matches with what doctors find after surgery under the microscope. The goal is to learn better ways to predict and assess treatment success.
Houston, TexasAges 18 years+ - NCT05029999RecruitingPhase 1
Test drugs for HER2-negative advanced breast cancer
This Phase 1 trial tests a combination of immune-targeting drugs (a CD40 medicine and a substance that helps immune cells act) plus chemotherapy in people with HER2-negative advanced breast cancer that has progressed. It aims to find a safer dose and see whether the treatment can shrink tumors or slow the cancer.
Chicago, IllinoisAges 18–99 - NCT05059379RecruitingPhase 3
