Nanjing, JiangsuAges 18–45 - NCT05974475Recruiting
Personalized modeling during targeted lung radiation for early cancer
This trial studies how detailed tests (“multi-omics” modeling) can improve how doctors plan and deliver stereotactic body radiotherapy (SBRT) for early-stage non-small cell lung cancer. It may help make treatment planning more precise for cancers in stages I–II.
Milan, ItalyAges 18 years+ - NCT05974696Recruiting
Registry for aggressive pituitary tumors (Aggressive PitNETs)
This study is a research registry that collects information from people with aggressive pituitary tumors. It may help researchers better understand these tumors by building a large, shared dataset over time.
LyonAges 18 years+ - NCT05974774RecruitingPhase 3
Intermittent hormone therapy for metastatic prostate cancer with low PSA
This trial studies whether taking hormone therapy in breaks (instead of continuously) can work for people with metastatic prostate cancer whose PSA is very low after prior treatment with hormone-deprivation plus an AR pathway inhibitor. It may help reduce time on treatment while still keeping cancer controlled.
CopenhagenAges 18–100 - NCT05974995Recruiting
Robotic or standard surgery for early uterine cancer in obesity
This trial compares robotic-assisted surgery versus standard laparoscopic surgery for people with early-stage uterine (endometrial) cancer and a BMI of 30 or higher. The goal is to see which approach is safer and works better for this group.
RomeAges 18–75 - NCT05975593Recruiting
Study how radiation affects tumor biology in cervical or pancreatic cancer
This study looks at how radiotherapy changes the tumor environment, using lab samples collected during treatment. It may help researchers understand why radiation works differently for different people and could improve future treatment planning.
St Louis, MissouriAges 18 years+ - NCT05975775Recruiting
Laparoscopic prostate surgery for localized cancer, as an outpatient
This trial looks at a planned, minimally invasive (laparoscopic) prostate removal for men with localized prostate cancer done as an outpatient. It aims to understand how this approach fits into care after discussion by a group of specialists.
LyonAges 18 years+ - NCT05975749RecruitingPhase 2
Trastuzumab, serplulimab, and chemo after stomach cancer surgery
This Phase 2 study looks at whether adding serplulimab to trastuzumab and chemotherapy after surgery can lower the chance of stomach cancer coming back. It is for people with HER2-positive stage II–III stomach adenocarcinoma who have already had curative surgery with lymph node removal.
Shanghai, Shanghai MunicipalityAges 20–80 - NCT05976412Recruiting
Radiation to lymph nodes after surgery for higher-risk breast cancer
This trial looks at whether adding targeted radiation to lymph nodes after breast surgery can lower the chance of breast cancer coming back in people with higher-risk, node-negative disease. If you qualify, you may get a planned radiation approach designed for prevention, not treatment of spread.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05976490Recruiting
Support program for people newly diagnosed with brain cancer
This study tests a “NeuroPathways” support intervention for adults who are within 6 weeks of being diagnosed with a malignant (cancerous) brain tumor. It may help patients cope and navigate care during the early, stressful period after diagnosis.
Boston, MassachusettsAges 18 years+ - NCT05976815Recruiting
Exercise added to chemotherapy before breast cancer surgery
This study tests whether adding a supervised physical exercise program around the time of “before-surgery” chemotherapy helps people with newly diagnosed breast cancer. You may be assigned to an exercise group or a usual-care group, and the researchers will compare outcomes between them.
Vila Nova de Gaia, Porto DistrictAges 18 years+ - NCT05977036Recruiting
Biomarker test to guide early treatment for HR+ HER2- breast cancer
This study uses a lab “biomarker” test to help doctors choose the best first treatment for people with HR+ (hormone-receptor positive), HER2-negative metastatic or unresectable breast cancer. The goal is to see if this biomarker-guided approach can improve which therapy you start with.
St Louis, MissouriAges 18 years+ - NCT05976997RecruitingPhase 2
Test duvelisib plus chidamide for newly diagnosed PTCL
This trial studies whether the combination of duvelisib and chidamide can treat newly diagnosed peripheral T-cell lymphoma (PTCL). Because it is a single-arm study, everyone gets the treatment, and the team monitors response and safety.
Wuhan, HubeiAges 18–70 - NCT05977621Recruiting
Ultrasound imaging to guide radiation needle placement
This trial tests a guidance technique that uses ultrasound images matched to MRI (a real-time “map”) to help track the needle position during treatment for cervical or uterine cancer. It may help make radiation treatments more precise for people who are getting curative-intent radiation with brachytherapy.
Durham, North CarolinaAges 18–90 - NCT05977803Recruiting
MRI study of brain radiation injury in lung cancer
This study looks at how a specific kind of MRI picture (called the CEST sequence) can help characterize radiation-related brain injury and changes in brain metastases from lung cancer. It may help doctors better interpret follow-up scans after radiation, without changing your cancer treatment.
ParisAges 18 years+ - NCT05977907RecruitingPhase 2
Immunotherapy before surgery for head and neck cancer
This Phase 2 trial tests pembrolizumab and an investigational drug (IO102-103) given before surgery for certain non-bulky head and neck squamous cell cancers. The goal is to shrink the cancer and improve chances of cure by treating it before the operation.
Washington D.C., District of ColumbiaAges 18 years+ - NCT05977998RecruitingPhase 2
Paclitaxel given during surgery for stomach cancer spread to the belly
This trial studies whether adding paclitaxel chemotherapy around the time of surgery can improve outcomes for people with stomach or gastroesophageal junction adenocarcinoma that has spread to the lining of the abdomen (peritoneum). It targets cancers confirmed by testing of belly fluid or by laparoscopy/laparotomy, and may help by treating cancer cells right at the time of surgery.
Houston, TexasAges 18 years+ - NCT05978141Recruiting
