Recruiting studies
- NCT05513638Recruiting

NanjingAges 60–90 - 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 - NCT05946213RecruitingPhase 3
Shorter radiation treatment for high-risk prostate cancer
This trial tests whether a shorter course of radiation works as well as the usual longer course for people with high-risk prostate cancer. The goal is to keep cancer control while possibly reducing treatment time and inconvenience.
Birmingham, AlabamaAges 18 years+ - NCT06347705RecruitingPhase 2
Vaccine plus standard therapy for prostate cancer before surgery
This trial tests an experimental vaccine (2141-V11) combined with standard hormone therapy and an anti-androgen drug before prostate removal surgery. It aims to see if the combination can help the immune system fight the cancer more effectively.
Basking Ridge, New JerseyAges 18 years+ - NCT07180381Recruiting
A closer look at prostate MRI to avoid unnecessary biopsies
This study uses repeat MRI scans to monitor men with an intermediate suspicion of prostate cancer, aiming to reduce unnecessary biopsies while still catching significant cancers early.
Emmen, DrentheAges 18 years+ - NCT07219303Recruiting
Adaptive radiation therapy for intermediate- or high-risk prostate cancer
This trial tests a type of radiation that adjusts to changes in your prostate during treatment. It aims to improve accuracy and reduce side effects for men with intermediate- or high-risk prostate cancer.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07225205Recruiting
Home IV fluids after bladder removal surgery
This trial tests if giving IV fluids at home after bladder removal surgery is safe and helpful. It aims to reduce dehydration and hospital visits after you go home.
Baltimore, MarylandAges 18 years+ - NCT07308990Recruiting
Comparing limited vs. full lymph node removal during prostate surgery
This trial compares two types of lymph node removal during prostate cancer surgery to see if removing fewer lymph nodes is just as effective. It is for men with prostate cancer that has not spread beyond the pelvis.
Lyasny, Minsk OblastAges 18 years+ - NCT07325721RecruitingPhase 2
Shorter radiation with a focused boost for high-risk prostate cancer
This trial tests a shorter course of radiation therapy with an extra 'boost' to the most aggressive part of the tumor, combined with hormone therapy, for men with high-risk or locally advanced prostate cancer that has not spread outside the pelvis.
Charleston, South CarolinaAges 18 years+ - NCT07339761Recruiting
Sexual health support for bladder cancer patients
This study from the University of Aarhus looks at ways to support sexual health in people who have been treated for bladder cancer. If you are a Danish-speaking adult who had bladder cancer treatment about a year ago and have noticed changes in sexual function, you may be able to join.
AarhusAges 18 years+ - NCT07398690Recruiting
MRI-guided approach for prostate cancer diagnosis
This trial tests if using MRI and a blood test called PHI can help decide who needs a prostate biopsy. It aims to avoid unnecessary biopsies while still catching cancer early.
SeoulAges 20 years+ - NCT07635238RecruitingPhase 2
Lower Dose Radiation for Prostate Cancer
This trial tests whether a lower dose of radiation can effectively treat prostate cancer while reducing side effects. It is for men with certain types of prostate cancer that are visible on an MRI.
Basking Ridge, New JerseyAges 18 years+ - NCT07643558Recruiting
Fish oil and weight training for cancer patients' muscle health
This study tests whether taking fish oil supplements combined with progressive weight training exercises can help preserve or build muscle strength in cancer patients undergoing treatment. The goal is to help you maintain physical function and quality of life during cancer care.
Erlangen, BavariaAges 18 years+ - NCT06396806Enrolling by invitation
Sigmoid cancer surgery with or without dye tracing
This trial compares two surgical approaches for sigmoid colon cancer to see if using a special dye to see lymph nodes during surgery leads to better outcomes.
Guangzhou, GuangdongAges 18–75 - NCT07757490Recruiting
Sonablate HIFU registry for prostate cancer and BPH
This study is a registry that collects information from men who have had Sonablate HIFU treatment for prostate cancer or enlarged prostate (BPH). It will help doctors learn more about how well this treatment works in real life.
Indianapolis, IndianaAges 18 years+ - 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+ - NCT06461793RecruitingPhase 2
Higher dose radiation with hormone therapy for high-risk prostate cancer
This trial tests a higher dose of radiation given in fewer sessions (hypofractionated) combined with hormone therapy for men with high-risk prostate cancer that has not spread. A gel spacer called SpaceOAR is used to protect the rectum. The goal is to see if this approach is safe and effective.
SeoulAges 20 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+ - NCT04742621Recruiting
Liver transplant for colon cancer that spread only to the liver
This trial studies using a liver transplant to treat colon or rectal cancer that has spread to the liver but not anywhere else. It may help people with limited liver-only spread whose disease hasn’t worsened for a while.
New York, New YorkAges 18–65 - NCT06420115Recruiting
Comparing needle sizes for prostate MRI-targeted biopsy
This study compares two different needle sizes used during a prostate biopsy to see which one finds cancer more accurately and causes fewer side effects. It is for people who have not been diagnosed with prostate cancer before and have a suspicious MRI finding.
Padua, ItalyAges 18 years+ - NCT05935124Recruiting
White light or narrow-band imaging for colon polyp detection
This trial compares two camera light styles during screening colonoscopy to see which one better finds polyps on the right side of the colon. If you’re having a routine screening and have no concerning symptoms, the results may help improve how doctors spot polyps early.
Sydney, New South WalesAges 18 years+ - NCT05390827Recruiting
Remote digital health data collection for cancer patients
This study collects health data from digital devices (like Apple iPhone or Android) to help researchers understand how physical activity and other measures change during cancer treatment. It may be a way for you to contribute to research from home.
New York, New YorkAges 18 years+ - NCT07492927Recruiting
Liquid biopsy for prostate cancer diagnosis
This study uses a blood test to detect prostate cancer more accurately than traditional methods. It looks for genetic material from cancer cells to help decide if a prostate biopsy is needed.
Chicago, IllinoisAges 18 years+ - NCT06461819RecruitingPhase 2
