- NCT05929612RecruitingPhase 2
Low-dose targeted radiation alone for marginal zone lymphoma
This Phase 2 study tests whether very low-dose radiation (adjusted based on how you respond) can treat marginal zone lymphoma without adding other medicines at first. It may help some people by reducing radiation exposure while still controlling the cancer.
Houston, TexasAges 18 years+ - NCT05929976Recruiting
Study of gut and blood chemistry in children with new leukemia
This study looks at the gut microbiome (tiny organisms in the gut) and metabolome (small chemicals in the body) in children and teens with newly diagnosed ALL. It may help researchers understand what is happening in the body early in treatment and could guide future, more personalized care.
New York, New YorkAges 3–18 - NCT05929885RecruitingPhase 2
Genotype-guided chemo for metastatic pancreatic cancer
This trial tests a chemo plan that includes different drugs and adjusts the irinotecan dose based on a patient’s genetic test (UGT1A1). It’s designed for people with pancreatic cancer that has spread or cannot be removed with surgery.
SingaporeAges 21–99 - NCT05930665RecruitingPhase 2
Immunotherapy plus chemo for unresectable pleural mesothelioma
This trial tests whether adding cadonilimab (an immune treatment) and bevacizumab (a medicine that targets blood supply to tumors) to standard chemotherapy can control pleural malignant mesothelioma that cannot be removed with surgery. It’s meant for people who have not yet started medicine for advanced disease and who meet health and blood test requirements.
Guangzhou, GuangdongAges 18 years+ - NCT05930860Recruiting
Endoscopic treatment for certain superficial stomach growths
This trial studies how safe and effective a procedure called endoscopic submucosal dissection (ESD) is for treating certain early, superficial stomach (gastric) growths. It may be an option if your growth fits the endoscopy criteria and you are not a good candidate for stomach surgery.
RomeAges 18 years+ - NCT05931068Recruiting
Measuring energy use during major liver surgery
This study looks at how much energy your body uses during major liver surgery by measuring breathing and metabolism. It may help doctors better plan care around surgery and understand how your body responds.
MaastrichtAges 18 years+ - NCT05931393RecruitingPhase 2
Cabozantinib retreatment after it helped, in kidney cancer study
This Phase 2 study tests a “next-step” cabozantinib strategy for advanced kidney cancer (RCC) after your cancer previously responded to cabozantinib and then progressed. It aims to see if re-using cabozantinib in a planned sequence can control the cancer again with manageable side effects.
Dallas, TexasAges 18 years+ - NCT05932212RecruitingPhase 2
Study drug for vulvar cancer after prior treatment failure
This Phase 2 trial tests AK104 in people with recurrent or metastatic vulvar cancer that cannot be cured with surgery or strong radiation. It may help shrink tumors or slow growth, especially if you’ve already tried standard treatments or couldn’t tolerate them.
Fuzhou, FujianAges 18–80 - NCT05931419Recruiting
Radiation versus surgery for high-risk prostate cancer
This trial compares two standard treatment options—radiation or surgery—for people with high-risk prostate cancer that has not spread. The goal is to see which approach works better for long-term cancer control and side effects.
AlkmaarAges 50–75 - NCT05932199RecruitingPhase 1/Phase 2
Durvalumab and tremelimumab before surgery for mesothelioma
This Phase 1/2 study tests the immune medicines durvalumab and tremelimumab, with or without chemotherapy, given before surgery for mesothelioma. It aims to shrink the tumor and improve safety and outcomes so more patients can have their cancer fully removed.
Durham, North CarolinaAges 18 years+ - NCT05932680RecruitingPhase 2
Continue teclistamab for a limited time in responding patients
This Phase 2 trial looks at stopping or limiting teclistamab after you’ve already had a good ongoing response. It aims to see if people can safely continue to benefit while using the medicine for a shorter time.
Little Rock, ArkansasAges 18 years+ - NCT05932862RecruitingPhase 1
Test drug XL309 for advanced tumors with HRR gene changes
This early-phase study tests XL309 (and sometimes a mix of XL309 with another treatment) in people whose advanced solid tumors have specific DNA-repair gene changes, such as BRCA1/2 or other HRR-related changes. It aims to see how well the drug works and what dose is safest for these cancers.
Fountain Valley, CaliforniaAges 18 years+ - NCT05933122Recruiting
Sexual health support after rectal cancer surgery
This study looks at how common sexual difficulties are in women after rectal cancer surgery, and whether a sexologist-led support program can help. If you qualify, you may be asked about sexual well-being and take part in counseling support.
Brive-la-GaillardeAges 18 years+ - NCT05933395RecruitingPhase 2
Targeted treatment for ER+ breast cancer after CDK4/6 therapy
This Phase 2 study tests a genetically guided treatment plan for ER-positive breast cancer that has progressed after CDK4/6 therapy. It may help by matching treatment to tumor genetic changes.
Lebanon, New HampshireAges 18 years+ - NCT05933239RecruitingPhase 2
PET-like scan using a special protein in lung cancer
This Phase 2 study tests whether a new imaging medicine (a radiopharmaceutical) can highlight immune cells called macrophages in people with non-small cell lung cancer. It may help doctors better “see” and evaluate tumor tissue before a surgical biopsy or removal.
Jette, Brussels CapitalAges 18 years+ - NCT05933889Recruiting
Study of robotic throat surgery for early oropharyngeal cancer
This study looks at how well different robotic surgery approaches work for people with early oropharyngeal squamous cell carcinoma (throat cancer). You may be asked for consent for extra tissue and imaging analysis to help researchers understand patterns related to outcomes.
LondonAges 18 years+ - NCT05933733Recruiting
Salvage treatment for breast cancer that returned locally
This trial looks at how well “salvage” treatments work for breast cancer that has come back only in the local area (like the chest wall or nearby lymph nodes), without spreading to distant organs. It also tracks side effects to better understand the risks and benefits for patients who need additional treatment.
SeoulAges 18–100 - NCT05933876Recruiting
Radiation study for limited spread cancer
This trial looks at whether giving radiation treatment to tumors in people with a limited number of metastases can help control the cancer. It is for adults with certain cancer types that have spread to specific organs, and who can manage daily activities with little or no help.
Albacete, AlbaceteAges 18 years+ - NCT05934513RecruitingPhase 1/Phase 2
Study drug GFH009 for relapsed lymphoma after prior treatments
This early-phase study tests GFH009 (given alone) in adults with peripheral T-cell lymphoma that has come back or not responded. It may help shrink lymphoma in people who have already tried several other treatments.
Guanzhou, GuangdongAges 18–75 - NCT05934032Recruiting
Genomic medicine for non-surgical lung cancer
This trial is part of a lung cancer network that uses genetic (DNA) testing to better understand and treat non-surgical lung cancer. You might be eligible if you have certain stages of non-small cell lung cancer and can consent to participate.
CologneAges 18 years+ - NCT05935150Recruiting
Skipping lymph node surgery in early breast cancer
This trial studies whether you can safely avoid a lymph node biopsy in the armpit for early breast cancer when scans and exams look negative. It may reduce surgery-related side effects while still keeping cancer care on track.
Nanjing, JiangsuAges 18–70 - NCT05935189Recruiting
Hepatocellular cancer tissue registry for Armenian patients
This study builds a tissue (sample) registry for people with liver cancer to help researchers learn more and improve future care. It’s mainly about confirming your diagnosis and collecting consent for using your biopsy tissue.
YerevanAges Any age - NCT05935384Recruiting
Blood tests to track response to cancer therapy
This study follows how cancer responds to standard (usual) treatment by using blood samples and de-identified health data. It may help researchers understand whether “liquid biopsy” blood testing can reflect how well therapy is working.
Skokie, IllinoisAges 18 years+ - NCT05936034Recruiting
Hearing aid vs no hearing aid during platinum chemotherapy
This study compares how patients’ quality of life changes when people who have hearing loss from platinum chemotherapy use a hearing aid versus not using one. It may help understand whether hearing aids improve daily life during treatment.
