BrusselsAges 18 years+ - NCT07249281Recruiting
New MRI scan for better prostate cancer detection
This study tests a new type of MRI scan (called TDDMRI) that looks at tiny details in prostate tissue to better detect cancer. If you are already getting a prostate MRI, this extra scan may help doctors find cancer more accurately.
Beijing, Beijing MunicipalityAges Any age - NCT07231627Recruiting
Using AI to improve prostate cancer detection from MRI
This trial tests whether an artificial intelligence (AI) program can help doctors decide when a prostate biopsy is needed. It is for men who have had a prostate MRI that shows either a low-risk (PIRADS 1-2) or uncertain (PIRADS 3) spot, along with a higher-than-normal PSA level. You may qualify if you have certain risk factors like a high PSA density, suspicious digital rectal exam, or family history of prostate cancer.
Little Rock, ArkansasAges 40 years+ - NCT05648253Recruiting
Hyivy device after pelvic radiation for vaginal health
This study checks whether a special vaginal device (Hyivy) is safe and workable after pelvic radiation for certain cancers. You may be asked to use it for 12 weeks to help with vaginal changes after treatment, and you would visit the study team regularly.
Kitchener, OntarioAges 18 years+ - NCT06684652Recruiting
Comparing targeted plus standard biopsies for prostate cancer diagnosis
This trial tests whether adding a targeted biopsy to a standard sextant biopsy improves the detection of prostate cancer. It is for men aged 45 to 85 who have a suspicious spot on an MRI of their prostate and have not had a biopsy before.
Beijing, Beijing MunicipalityAges 45–85 - NCT04249154RecruitingPhase 2
After prostate surgery, test radiation plus hormone shots
This trial studies whether giving a shorter-course radiation plan after prostate surgery, along with hormone shots (LHRH), can improve outcomes for people with higher-risk prostate cancer. You may be eligible if your PSA (a blood marker) is either still low but high-risk by pathology, or it has started to rise again after surgery.
Montreal, QuebecAges 18 years+ - NCT06392737Recruiting
AI-guided MRI vs routine MRI for prostate biopsy
This study tests whether an artificial intelligence tool for MRI can improve the results of targeted prostate biopsy, compared to the usual method. It could help diagnose prostate cancer more accurately with fewer needles.
Beijing, Beijing MunicipalityAges 45–85 - NCT06850688Recruiting
Remote monitoring after colorectal surgery
This trial tests a remote monitoring system to keep an eye on patients after colorectal surgery. It aims to see if this helps recovery and reduces hospital readmissions.
AngersAges 18 years+ - NCT06840977Recruiting
Low dose chemo for older adults with colorectal cancer
This trial tests a lower-dose chemotherapy regimen for adults aged 70 or older with metastatic colorectal cancer that has not been treated yet. It aims to see if a gentler approach can still be effective and easier to tolerate.
Genova, GEAges 70–99 - NCT06835725RecruitingPhase 2
Comparing two prostate radiation schedules for intermediate risk
This trial compares giving radiation in 2 treatments versus 5 treatments for prostate cancer that hasn't spread. It's for men with low or intermediate risk prostate cancer who are healthy enough to undergo a short course of targeted radiation.
Surrey, British ColumbiaAges 18 years+ - NCT05574647Recruiting
Fast prostate MRI and guided biopsy testing for prostate cancer
This study checks whether a faster prostate MRI and image-matching (image-fusion) can better find suspicious spots so doctors can target a biopsy. If you have concerning prostate exam results or PSA blood test results, you may get an MRI and, if something looks suspicious, a biopsy using MRI images.
Southend-on-Sea, EssexAges 18 years+ - NCT06591819RecruitingPhase 2
Shorter pelvic radiation with HDR boost for prostate cancer
This trial tests a shorter course of radiation therapy (hypofractionated whole-pelvis radiation) combined with a high-dose-rate (HDR) brachytherapy boost for men with high-risk or unfavorable intermediate-risk prostate cancer. The goal is to see if this approach controls cancer while possibly reducing side effects.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06517901Recruiting
Comparing two MRI-guided biopsy methods for prostate cancer
This trial compares two ways to use MRI images during a prostate biopsy to see which finds cancer better. It looks at 'fusion' biopsy (where a computer combines MRI with live ultrasound) versus 'cognitive' biopsy (where the doctor mentally matches the MRI to the ultrasound).
Burlington, MassachusettsAges 18 years+ - NCT06482645Recruiting
Testing a new biopsy method for prostate cancer diagnosis
This study is testing a new approach to prostate biopsy that takes samples from around a suspicious area seen on MRI. It aims to see if this method can better detect prostate cancer compared to standard biopsy.
Beijing, Beijing MunicipalityAges 45–85 - NCT06451445Recruiting
Focal IRE treatment for intermediate-risk prostate cancer
This trial tests a new focal treatment called IRE (irreversible electroporation) that uses electrical pulses to destroy prostate cancer cells while sparing healthy tissue. It is for men with intermediate-risk prostate cancer that has not spread outside the prostate gland.
Toronto, OntarioAges 50 years+ - NCT06427824Recruiting
Health tests for older adults with bladder cancer before bladder removal
This study looks at how a series of health tests (called a comprehensive geriatric assessment) can help doctors plan care for older adults with bladder cancer who are having their bladder removed. The goal is to improve recovery and quality of life.
Chicago, IllinoisAges 65 years+ - NCT06402357RecruitingPhase 2
Focused Ultrasound for Recurrent Prostate Cancer After Radiation
This trial tests if a focused ultrasound treatment can safely and effectively treat prostate cancer that has come back after radiation therapy. The ultrasound uses sound waves to heat and destroy cancer cells in a specific area of the prostate while sparing healthy tissue.
Gainesville, FloridaAges 18 years+ - NCT06391034RecruitingPhase 2
MRI scan with pyruvate for prostate cancer
This trial uses a special MRI scan (with hyperpolarized pyruvate, a naturally occurring substance) to look at prostate cancer in more detail. It aims to help doctors understand how the cancer is responding to treatment or how it might behave.
San Francisco, CaliforniaAges 18 years+ - NCT06126731RecruitingPhase 1/Phase 2
Antibiotics plus enzalutamide for advanced prostate cancer
This trial tests whether adding specific antibiotics (amoxicillin, metronidazole, vancomycin, ciprofloxacin) to enzalutamide can help treat advanced prostate cancer that has stopped responding to other treatments. It aims to see if changing gut bacteria can make the cancer therapy work better.
BellinzonaAges 18 years+ - NCT05754580Recruiting
Boost radiation for intermediate or higher-risk prostate cancer
This study tests a stronger, focused radiation plan for intermediate to higher-risk prostate cancer. It combines a high-dose internal radiation “boost” with external radiation to try to improve cancer control while keeping side effects manageable.
Omaha, NebraskaAges 19 years+ - NCT06052683Recruiting
Comparing radiation side effects for low-risk prostate cancer
This trial compares two types of radiation therapy (SBRT and LDR brachytherapy) for men with low-risk or favorable intermediate-risk prostate cancer. The goal is to see which treatment causes fewer side effects.
Québec, QuebecAges 18 years+ - NCT05998187RecruitingPhase 3
Botox injections for fecal incontinence
This trial tests whether botulinum toxin (Botox) injections into the rectum can improve bowel control in people with active fecal incontinence. It aims to help those who haven't gotten better with standard treatments like diet changes or pelvic floor therapy.
Rouen, FranceAges 18 years+ - NCT05835206RecruitingPhase 2
Drug to reduce antibiotic-resistant gut bacteria
This Phase 2 study tests whether an investigational treatment can help clear or reduce antibiotic-resistant bacteria living in the gut. It may help prevent these germs from causing future infections by targeting specific resistant bacteria found on stool or rectal swabs.
Atlanta, GeorgiaAges 18 years+ - NCT05697562Recruiting
Embolization treatment for hemorrhoid bleeding
This trial studies a procedure that blocks blood flow to bleeding hemorrhoids (called superior rectal arterial embolization). It may help people with hemorrhoid bleeding who are being considered for treatment, especially when bleeding is significant.
