Shorter radiation after breast surgery for certain node-positive cancer
This trial compares a shorter, more concentrated radiation schedule versus a standard shorter schedule after breast-conserving surgery. It looks at whether the treatment works well and is safe, especially for women whose lymph nodes also need radiation.
São Paulo, São PauloAges 18 years+ - NCT05041530Recruiting
Closing the belly after cancer surgery
This study tests a new way to close the belly after open surgery to remove cancer. It may help improve healing and reduce the chance of a hernia.
Medellín, AntioquiaAges 18–75 - NCT05429463RecruitingPhase 3
Surgery-ready lung cancer treatment with immunotherapy plus chemo
This trial studies adding an immunotherapy drug (sintilimab) to standard chemotherapy before surgery for resectable squamous non-small cell lung cancer. It aims to shrink the tumor and improve outcomes, while still keeping the cancer operable.
Hangzhou, ZhejiangAges 18–75 - NCT05636605Recruiting
Study lung cancer biology and why immunotherapy stops working
This study looks at lung cancer tissue and immune system changes to understand how and why immunotherapy resistance develops. It may help researchers find better ways to make immunotherapy work longer for future patients.
Yiwu, ZhejiangAges 18–80 - NCT05651672RecruitingPhase 2
Pemigatinib for advanced gut cancers with FGFR gene changes
This Phase 2 trial tests pemigatinib, a targeted medicine, for advanced or metastatic gastrointestinal (GI) cancers that have specific FGFR1–3 gene changes. It’s for people whose cancer has grown despite prior standard treatment, and who may benefit if their tumor has the right genetic change.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT05652192RecruitingPhase 2
SBRT radiation plus chemotherapy and immunotherapy for metastatic nasopharyngeal cancer
This trial tests whether adding targeted radiation (SBRT) to chemotherapy and an immunotherapy drug can help people with metastatic nasopharyngeal cancer live longer and control tumors. It may help by combining local tumor treatment with whole-body immune support.
Hangzhou, ZhejiangAges 18–75 - NCT03622983Recruiting
Biobank study for pelvic cancers and endometriosis samples
This study collects and stores biological samples (like tissue or other lab samples) from people with pelvic gynecologic cancers or endometriosis, and links them with imaging/radiology information. It may help researchers learn more about these conditions and how they behave over time.
CréteilAges 18 years+ - NCT05661786Recruiting
Study outcomes for hepatitis B with “indeterminate” disease phase
This trial studies what happens to people with hepatitis B who have hepatitis B surface antigen for more than 6 months, are “HBeAg-negative,” and have certain blood and liver-scarring levels despite normal or near-normal liver inflammation. It may help doctors understand the best care for this specific group before clear treatment phases.
Changzhou, JiangsuAges 18 years+ - NCT05659628RecruitingPhase 1
CD19 CAR-T plus PD-1 antibody for relapsed lymphoma
This Phase 1 study tests a new type of immune cell therapy (CD19 CAR-T) combined with an anti–PD-1 drug for people with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). It aims to improve cancer control when standard treatments have not worked or the cancer has come back.
Hangzhou, ZhejiangAges 18–75 - NCT04949282Recruiting
Lutetium-177 treatment for advanced somatostatin-positive tumors
This study looks at outcomes for adults with tumors that are advanced (can’t be fully removed or has spread) and are getting worse, where tests show somatostatin receptors. It aims to understand how treatment with lutetium-177 helps people in this situation.
Santiago de Compostela, A CoruñaAges 18–100 - NCT05673031Recruiting
PET/CT scan test for neuroendocrine tumors with a special tracer
This study uses a PET/CT scan with a small amount of radioactive tracer to see how neuroendocrine tumors are behaving in adults. It may help doctors better detect and evaluate these tumors, especially when symptoms suggest a carcinoid-type hormone problem.
Calgary, AlbertaAges 18–100 - 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 - NCT05672043Recruiting
Study genetic risks in children with malignant brain tumors
This study looks at genetic (DNA/molecular) features of malignant brain tumors in children. It may help doctors better understand tumor risk patterns and guide future treatment planning.
Beijing, Beijing MunicipalityAges birth–18 years - NCT05674305RecruitingPhase 3
Tested radiation alone vs added chemotherapy for EBV-negative after treatment
This Phase 3 trial compares giving radiation alone versus giving radiation at the same time as chemotherapy for nasopharyngeal cancer. It focuses on people whose EBV test becomes undetectable after one cycle of chemotherapy, to see which approach works best and is safest.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT04442334Recruiting
European registry for people with fatty liver
This registry collects health and lifestyle information from adults with suspected or confirmed fatty liver (NAFLD) to help researchers better understand the condition. You may be asked about diet, exercise, alcohol intake, and some liver-related tests.
AntwerpAges 18–100 - NCT05596578Recruiting
Study of lymph nodes during lung surgery for early lung cancer
This study looks at certain lymph nodes removed during surgery for non-small cell lung cancer (NSCLC) that has grown into the covering of the lung. The goal is to better understand lymph node involvement and help guide future treatment decisions.
LucerneAges 18 years+ - NCT05537922Recruiting
Study uses data to tailor lung cancer care with immunotherapy
This study collects and analyzes medical information (and sometimes tissue samples) to help personalize treatment plans for advanced non-small-cell lung cancer using immunotherapy. It may help researchers find which people benefit most and how treatment can be better matched to each patient.
Chicago, IllinoisAges 18 years+ - NCT05673681Recruiting
Melanoma patient registry for people with skin melanoma
This is a registry that collects information from people diagnosed with an invasive skin melanoma. It may help researchers understand who gets melanoma and how it’s diagnosed and treated over time.
Badalona, BarcelonaAges Any age - NCT04677205Recruiting
Tumor-to-lymph-node study after lung cancer surgery
This study looks at molecular (biologic) signals in the tumor and nearby lymph nodes after curative surgery for stage IIIA lung cancer. It may help doctors better understand the disease and improve future treatment planning.
BordeauxAges 18 years+ - NCT05676190Recruiting
Cell therapy using your own immune cells for colorectal cancer
This trial studies an immune cell treatment made from your own blood cells to treat colorectal cancer that has spread or progressed. You may be eligible if you have stage III–IV disease that can be measured on scans and if standard treatments have not worked or couldn’t be tolerated.
Chongqing, Chongqing MunicipalityAges 18–70 - NCT05682131RecruitingPhase 4
Study for children with certain relapsed leukemia

Chidamide to Prevent AML Return After Bone Marrow Transplant
This Phase 1/2 study tests whether chidamide can help prevent high-risk acute myeloid leukemia (AML) from coming back after an allogeneic bone marrow transplant (allo-HSCT). Participants must already be in complete remission and have recovered blood counts after transplant.
Chengdu, SichuanAges 18–65 - NCT04095195Recruiting
