This trial studies Actemra (tocilizumab) to slow or shrink adamantinomatous craniopharyngioma, a brain tumor that can recur after treatment. You may be eligible if you’re within the age range and have measurable tumor on scan, with specific rules about prior therapy and recovery.
Aurora, ColoradoAges 1–39 - NCT05233891Recruiting
Swedish-language study of scales used in breast reconstruction
This study checks whether certain rating tools (called “scales”) are working well for people having breast reconstructive surgery at Sahlgrenska University Hospital. It may help future patients because it improves how outcomes and symptoms are measured in the clinic.
GothenburgAges 18–100 - NCT05234177Recruiting
Blood test to track colorectal cancer after surgery
This study looks at a blood “DNA” test to see if it can help monitor colorectal cancer after surgery. It may benefit you by improving how doctors track cancer during routine follow-up visits.
Fort Smith, ArkansasAges 18 years+ - NCT05234307RecruitingPhase 1
Nivolumab plus PBF-1129 for advanced lung cancer
This Phase 1 trial tests a new combination of PBF-1129 with nivolumab (an immune therapy) for lung cancer that has come back or spread. It aims to find a safe dose and see whether the combination can shrink tumors and improve outcomes.
Columbus, OhioAges 18 years+ - NCT05235009Recruiting
Testing a urine and blood test to spot early cancer
This study checks whether a lab test using your urine and blood (plasma) can detect signs of cancer early in people who don’t have symptoms. It compares people with newly found cancer to people without cancer to see how accurate the test is.
StockholmAges 18–80 - NCT05236114Recruiting
Study of blood and tumor tests for lung cancer treatment
This study looks at how tumor and blood biomarker results can guide treatment for people with non-small cell lung cancer (NSCLC). Depending on the cancer stage, it may follow standard-of-care treatment plans around surgery or first-line immunotherapy.
Birmingham, AlabamaAges 18 years+ - NCT05236686Recruiting
Surgery to remove upper abdomen lymph nodes for ovarian cancer
This trial studies whether removing lymph nodes in the upper abdomen (hepatoceliac lymph nodes) improves outcomes for people with stage III or IV ovarian, fallopian tube, or primary peritoneal cancer that has spread to those lymph nodes. It also looks at how this surgery works for people with certain types of relapse, often alongside chemotherapy.
ShanghaiAges 18–75 - NCT05236972RecruitingPhase 3
PD-1 antibody after colon cancer surgery for dMMR stage III
This phase 3 trial studies a PD-1 antibody medicine given after surgery to help prevent stage III colon cancer from coming back. It is specifically for people whose tumor is mismatch repair–defective (dMMR) or MSI-H, which may make the cancer more responsive to immune-based treatment.
GuangzhouAges 18–75 - NCT05237258Recruiting
Compare palliative care approaches for people with high-risk AML
This study tests a specialized (targeted) palliative care program versus usual oncology care for people hospitalized with high-risk acute myeloid leukemia (AML). The goal is to see if this palliative approach improves comfort, support, and care planning during intensive treatment.
Birmingham, AlabamaAges 18–120 - NCT05237934Recruiting
Study collects tissue samples and tracks neuroendocrine tumors
This study looks at neuroendocrine tumors by collecting tissue (when available) and tracking how the disease behaves over time. It may help researchers better understand these cancers, including rare cases of adrenocortical cancer.
Bethesda, MarylandAges 18–120 - NCT05237986Recruiting
Study brain and thinking effects after CAR T therapy in youth
This study looks at how CAR T-cell treatment affects thinking, learning, and day-to-day brain function in children and young adults with certain blood cancers. You (and a caregiver) may complete online testing so researchers can track these changes over time and whether support is needed.
Los Angeles, CaliforniaAges 5 years+ - NCT05239338Recruiting
Preserving fertility after colorectal cancer
This study looks at how to help people protect their ability to have children after colorectal cancer. It mainly includes younger adults who were diagnosed for the first time and can complete study questionnaires.

Dostarlimab before colon surgery for mismatch-repair–deficient cancer
This study tests dostarlimab given before surgery for stage II or III colon cancer that has a specific DNA repair defect. It aims to shrink or control the cancer so that some people may be able to skip surgery if the results are good.
Iowa City, IowaAges 18 years+ - NCT05239624RecruitingPhase 2
Enfortumab plus pembrolizumab for muscle-invasive bladder cancer
This Phase 2 study tests how well two anti-cancer medicines—enfortumab vedotin and pembrolizumab—work for people with muscle-invasive bladder cancer that has spread to nearby lymph nodes (but not distant organs). It may help shrink the cancer and improve treatment outcomes before or around planning major surgery.
Miami, FloridaAges 18 years+ - NCT05240950RecruitingPhase 1
CAR-T cell therapy for colorectal cancer in the liver
This Phase 1 study tests an anti-CEA CAR-T cell treatment for people whose colorectal cancer spread to the liver but has been surgically removed with no visible remaining tumor. It aims to see if the treatment can better prevent the cancer from coming back, especially when early warning tests suggest leftover cancer cells.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05241093RecruitingPhase 2
HYML-122 plus cytarabine for FLT3-positive relapsed AML
This trial studies HYML-122 together with cytarabine to treat adults with FLT3-positive acute myeloid leukemia (AML) that has come back or did not respond to prior treatment. It may help shrink the leukemia and improve blood-count recovery when standard treatments haven’t worked.
