Atezolizumab for cancers with high mutation or immune markers
This trial tests atezolizumab, a cancer immunotherapy, for people whose tumors have high mutation levels (TMB), or are “MSI-high,” or have CMMRD. It may help shrink cancer or slow its growth by boosting the immune system’s ability to recognize the tumor.
BelfastAges Any age - NCT05856981RecruitingPhase 1
Testing ADU-1805 for advanced solid tumors safety
This early study tests whether ADU-1805 is safe in people with advanced solid tumors and checks how the body processes the drug. Depending on your cancer type, it may also be looking specifically at certain cancers that have not yet received PD-(L)1 immunotherapy.
Detroit, MichiganAges 18 years+ - NCT05877599RecruitingPhase 1
Study of a new treatment for advanced cancers with a specific gene change
This trial tests a new type of therapy (NT-175) for people with certain advanced cancers that have a specific genetic change. It might help if your tumor has the TP53 R175H mutation and you have the HLA-A*02:01 immune marker.
Gilbert, ArizonaAges 18 years+ - NCT05868226RecruitingPhase 1/Phase 2
Personalized cancer treatment study for advanced solid tumors
This study tests different treatments tailored to your cancer's biology. It aims to find which therapy might work best for you, potentially improving outcomes. You'd receive one of the study drugs, with close monitoring and support.
Birmingham, AlabamaAges 18 years+ - NCT05850130Recruiting
Acupuncture for nerve pain after colon cancer treatment
This trial tests whether acupuncture can relieve the nerve pain and tingling in the hands and feet that often occurs after treatment with oxaliplatin, a chemotherapy drug for gastrointestinal cancers. The study aims to help people manage this side effect and improve their daily comfort.
AmiensAges 18 years+ - NCT05642819Recruiting
MRI before and after surgery for abdominal cancers
This study uses extra detailed MRI scans before and/or around planned abdominal surgery to help researchers understand changes in the body. It includes people having surgery for certain cancers and some people having surgery for non-cancer (benign) conditions.
EdinburghAges 18 years+ - NCT05806931RecruitingPhase 2
Alternating two pills plus bevacizumab for advanced colon cancer
This Phase 2 study tests a treatment plan that alternates two cancer pills and adds bevacizumab (a blood-vessel drug) for metastatic colon cancer that has come back or worsened after standard treatment. It may help shrink tumors and slow disease growth after later-line therapy options.
Elizabeth, New JerseyAges 18 years+ - NCT05780684Recruiting
Personalized 5-FU dosing for advanced gastrointestinal cancer
This study tests whether doctors can safely find the best dose of 5-FU, a chemotherapy medicine, for people with advanced gastrointestinal cancers. The goal is to reduce side effects while still treating the cancer effectively.
Lebanon, New HampshireAges 18 years+ - NCT05786716RecruitingPhase 2/Phase 3
Trastuzumab plus pertuzumab for HER2-mutated cancers
This trial tests whether combining trastuzumab and pertuzumab can treat cancers that have HER2 amplification or an activating HER2 mutation. It looks at people ages 12 and older, and may include both children/teens and adults, using the study drug based on their HER2 test results.
