This early-phase study looks at how vitamin D replacement affects the immune system in Black/African American men with prostate cancer. It’s testing whether bringing vitamin D levels into a healthier range changes immune signals that may matter for cancer health.
Scottsdale, ArizonaAges 18 years+ - NCT05046444Recruiting
Testing tricky blood cancer diagnoses with advanced DNA sequencing
This study uses advanced DNA sequencing to figure out unclear or unusual blood (hematologic) conditions when standard tests are not enough. It may help your care team reach a more accurate diagnosis by better understanding what’s driving your illness.
MunichAges 18–99 - NCT05047094Recruiting
DaRT radiation plus pembrolizumab for head and neck cancer
This trial tests whether a targeted internal radiation treatment (DaRT) combined with pembrolizumab (an immune therapy) can shrink recurrent or metastatic head and neck squamous cell cancer that cannot be fully removed with surgery. It may help by making cancer more visible to the immune system while delivering localized radiation to a tumor area.
JerusalemAges 18 years+ - NCT05048212RecruitingPhase 2
Nivolumab, ipilimumab, and cabozantinib for kidney cancer brain spread
This Phase 2 study tests how well nivolumab plus ipilimumab, along with cabozantinib, treats untreated or worsening kidney cancer that has spread to the brain. It may help shrink brain tumors and slow the disease when standard local brain treatments aren’t the right option.
Houston, TexasAges 18 years+ - NCT05047510Recruiting
Fluorescent-guided surgery for liver cancer using GPC3 dye
This trial studies whether a special fluorescent dye that targets GPC3 can help surgeons find liver cancer more clearly during an operation. It may improve how accurately tumor tissue is identified while you have surgery for hepatocellular carcinoma.
Zhuhai, GuangdongAges 18–75 - NCT05048901RecruitingPhase 1/Phase 2
Cabozantinib plus lanreotide for advanced neuroendocrine tumors
This trial studies whether cabozantinib plus lanreotide can slow or shrink gastroenteropancreatic neuroendocrine tumors that have gotten worse despite previous treatments. If you qualify, you’ll be closely monitored for tumor response and side effects.
ChanghuaAges 20 years+ - NCT05049148Recruiting
Study platelets in brain and spinal tumors
This study looks at how blood “platelets” may be involved in brain or spinal (medullary) tumors by testing tumor tissue taken during surgery or biopsy. It may help researchers understand disease biology and guide future treatments.
ParisAges 18 years+ - NCT05049317Recruiting
Check urinary and sexual function after rectal cancer surgery
This study looks at how a specific rectal surgery (laparoscopic total mesorectum excision) affects urinary and sexual function after the operation. It may help patients by tracking what to expect and which factors relate to better recovery.
Wuhan, HubeiAges 18–70 - NCT05049538Recruiting
Liquid blood tests to predict endometrial cancer return
This trial studies whether blood “liquid biopsies” and tumor genetic testing can help predict whether endometrial cancer will come back after treatment. Results may help doctors plan follow-up and additional care based on a person’s recurrence risk.
Houston, TexasAges 18 years+ - NCT05049837Recruiting
Study lung cancer samples to understand relapse resistance
This trial looks at information and tissue from people with stage I to stage IIIA non-small cell lung cancer (NSCLC) who have surgery, sometimes with chemotherapy before surgery. Researchers want to understand why cancers come back (resistance) and how to better target treatments later.
Houston, TexasAges 18 years+ - NCT05050929RecruitingPhase 2
Targeted radiation for brain metastases using rapid imaging
This Phase 2 study tests a quicker, more targeted way to give radiation to brain metastases. It aims to treat tumors while using regular scans to check how well the treatment controls disease and how you feel.
Abbotsford British Columbia, British ColumbiaAges 18–100 - NCT05051046Recruiting
Screening colonoscopy with hypnosis for colorectal cancer
This trial studies whether using hypnosis during a screening colonoscopy can help people better tolerate the procedure and complete it comfortably. It’s for adults who are scheduled for a routine screening colonoscopy and meet specific safety and communication requirements.
AngersAges 18–100 - NCT05051059Recruiting
Life quality check after leg sarcoma surgery
This study checks how people with leg sarcoma are functioning and how satisfied they are with their quality of life after treatment. It mainly looks at patients at least one year after limb-sparing surgery, to understand long-term effects and support.
Leuven, Vlaams-BrabantAges 18–95 - NCT05051722Recruiting
Test DNA blood and tissue markers to detect gynecologic cancers
This study looks for “methylated DNA markers” (special DNA patterns) to help detect endometrial, ovarian, and cervical cancers, and to support doctors around planned procedures. It may help find cancer earlier or better sort out who needs closer treatment.
Phoenix, ArizonaAges 18 years+ - NCT05052671Recruiting
Blood test for residual cancer in resectable pancreatic cancer
This trial studies a blood test that looks for tiny traces of cancer-related DNA (called ctDNA) in people with pancreatic cancer that can be removed with surgery. The goal is to see whether this test can better predict how the cancer behaves and guide treatment decisions around surgery.
Oklahoma City, OklahomaAges 18–99 - NCT05053997Recruiting
Support program for vulnerable people with lung cancer
This trial tests a “navigation” support program to improve survival and quality of life for people with non-small cell lung cancer who are considered vulnerable. It may help you get the right care and support more smoothly throughout treatment.
AalborgAges 18 years+ - NCT05053854RecruitingPhase 1
Testing a PARP drug plus targeted radiation for bowel or pancreas tumors
This Phase 1 study tests how safe and effective it is to combine a PARP inhibitor (a targeted cancer medicine) with PRRT, a treatment that delivers radiation directly to certain tumor cells. It is for people with grade 2 neuroendocrine tumors from the pancreas or intestines, especially when scans suggest the tumor will take up the targeted radiation.
Melbourne, VictoriaAges 18 years+ - NCT05053607Recruiting
Text and Fitbit monitoring during isatuximab treatment
This trial follows people with multiple myeloma who are getting isatuximab through a vein (IV). It tests how well real-world health tracking (text/app messages and Fitbit data) works during treatment, and whether it can help care teams understand your experience.
Houston, TexasAges 18 years+ - NCT05053555Recruiting
High-dose radiation treatment for hard-to-remove liver tumors
This study uses a form of targeted radiation placed inside/near the liver to treat liver tumors that can’t be surgically removed. It’s meant to shrink or control tumors, especially when they sit near blood vessels or other sensitive organs.
Houston, TexasAges 19 years+ - NCT05053867RecruitingPhase 3
Inhaled drug to treat lung bleeding in ventilated cancer patients
This Phase 3 study tests whether inhaled tranexamic acid can reduce lung bleeding (pulmonary hemorrhage) in people with cancer who are on a breathing machine. If you qualify, you may receive the study drug to help stop bleeding in the lungs.
Houston, TexasAges 18 years+ - NCT05054257RecruitingPhase 1
CAR T19 for hard-to-treat blood cancers that have CD19
This Phase 1 study tests CAR T cells designed to attack cancer cells that carry a marker called CD19. It’s for adults with certain relapsed or treatment-resistant B-cell leukemias (ALL) or lymphomas (NHL) where other treatments may not have worked.
PragueAges 18–80 - NCT05054296RecruitingPhase 2
Exercise and Fitbit monitoring to lower heart risk in prostate cancer
This Phase 2 study tests whether a structured exercise and lifestyle program, tracked with a Fitbit, can reduce cardiovascular (heart) risk in men with prostate cancer on hormone therapy. It also checks whether this is safe and feasible while monitoring symptoms and fitness changes.
Houston, TexasAges 18 years+ - NCT05055635RecruitingPhase 2
Proton radiation for anal cancer that came back after prior treatment
This trial studies a focused type of proton radiation (“pencil beam”) to treat anal cancer that has returned after you previously had radiation. It may help by aiming treatment more precisely and giving another chance at cure when doctors think it can still be treated.
Aarhus N, AarhusAges 18 years+ - NCT05054413Recruiting
Expert guideline survey for prostate cancer care
This study uses a structured expert survey to help build clear, agreed-upon guidelines for prostate cancer care. If you’re a board-certified clinician who actively treats prostate cancer, your input can help shape how care is recommended.
