Accra, AccraAges 5–17 - NCT06336187Recruiting
Active monitoring for small kidney tumors
This study tests whether closely monitoring small kidney tumors (less than 4 cm) with regular imaging is a safe and effective option for people who cannot or choose not to have immediate treatment. It involves a biopsy at the start to confirm the tumor type.
NovaraAges 18 years+ - NCT06343077RecruitingPhase 2
Hiltonol injection for prostate cancer on active surveillance
This trial tests a drug called Hiltonol (Poly-ICLC) given directly into the prostate tumor along with an injection under the skin. It is for men with low-risk prostate cancer who are on active surveillance, to see if the drug can slow or stop the cancer from growing.
New York, New YorkAges 18 years+ - NCT06537154RecruitingPhase 2/Phase 3
Neoadjuvant therapy for bladder cancer with active surveillance
This trial tests whether people with muscle-invasive bladder cancer can safely avoid immediate surgery or radiation after a short course of chemotherapy. Instead, they would be closely monitored and only treated if the cancer comes back.
Vancouver, British ColumbiaAges 19 years+ - NCT05783661RecruitingPhase 4
Antibiotic plan guided by infection tracking in cirrhosis
This study compares standard antibiotic treatment versus antibiotic choices guided by local infection tracking (epidemiological surveillance) in people with cirrhosis who have an acute worsening and likely a bacterial infection. It may help doctors choose antibiotics more accurately and safely in this high-risk situation.
BarcelonaAges 18 years+ - NCT07262138Recruiting
Active monitoring for older women with early breast cancer
This trial studies whether active monitoring (watchful waiting) can be a safe option instead of immediate surgery or other treatments for women 70 and older who have a small, slow-growing type of breast cancer. If you join, you will not have surgery or other treatments right away, but your cancer will be closely watched.
Pittsburgh, PennsylvaniaAges 70 years+ - NCT07345286Recruiting
Studying fever illness care in DRC
This study is looking at how to better care for people with fever in the Democratic Republic of the Congo. If you have a fever now or very recently, you may be able to join and help doctors learn more about it.
KinshasaAges 2 months+ - NCT07351461Recruiting
Anxiety in men on active surveillance for early prostate cancer and their partners
This study looks at anxiety levels in men who have chosen active surveillance for early prostate cancer, as well as in their partners or significant others. It aims to understand how this approach affects emotional well-being.
LilleAges 18 years+ - NCT07357298RecruitingPhase 3
Brain MRI surveillance for stage IV breast cancer
This trial tests whether regular brain MRI scans can help detect brain metastases early in patients with stage IV breast cancer who do not yet have any known brain metastases. The goal is to see if early detection improves outcomes.
Miami, FloridaAges 18 years+ - NCT07370675Recruiting
Active surveillance for Bethesda IV thyroid nodules
This study is testing whether it is safe to simply monitor (watch closely) a small thyroid nodule that has a certain biopsy result (Bethesda IV) instead of removing it right away. You would not receive a treatment, but would have regular checkups and ultrasounds to see if the nodule changes.
CopenhagenAges 30 years+ - NCT00949819Recruiting
Active surveillance study for localized prostate cancer
This trial studies a “watchful waiting” approach, where doctors closely monitor certain prostate cancers with regular checkups and repeat biopsies. It may help people avoid or delay treatment side effects while watching for signs the cancer needs treatment.
Los Angeles, CaliforniaAges 30–85 - NCT02609685Recruiting
Active monitoring for tiny papillary thyroid cancer
This study looks at whether closely watching (without immediate surgery or treatment) a very small thyroid cancer can be safe. You may benefit by avoiding unnecessary procedures, while the team monitors your thyroid and any changes over time.
Los Angeles, CaliforniaAges 18 years+ - NCT07513389RecruitingPhase 2
HPV throat cancer trial skipping radiation with blood tests
This study tests whether patients with a specific type of HPV-positive throat cancer can safely skip radiation after surgery by using blood tests to monitor for cancer recurrence. The goal is to reduce side effects while keeping patients cancer-free.
Charleston, South CarolinaAges 18 years+ - NCT07443579Recruiting
Mammogram order study for breast cancer survivors
This trial tests if changing the order of mammogram views makes the exam more comfortable for women who have had breast cancer surgery and radiation. You may be able to join if you are due for your first check-up mammogram after finishing treatment.
Beaumont, DublinAges 18 years+ - NCT07503717Recruiting
Brain scan surveillance in HER2-positive metastatic breast cancer
This study tests whether regular brain scans (surveillance) help spot brain metastases early in people with HER2-positive breast cancer that has spread to other parts of the body. Participation involves being randomly assigned to either routine brain scans or no extra scans to see which approach is better.
BeaumontAges 18 years+ - NCT07572370Recruiting
Reducing Follow-up Visits After Breast Cancer Treatment
This study tests whether patients who have finished breast cancer treatment and are doing well can safely have fewer doctor visits and scans. Researchers want to see if reducing routine surveillance affects quality of life and health outcomes.
DublinAges 18 years+ - NCT07669298Recruiting
Monitoring vs chemoradiation for early rectal cancer
This study compares two approaches after early-stage rectal cancer is removed: either careful monitoring or a follow-up treatment with chemotherapy and radiation. The goal is to see which strategy works better to keep the cancer from returning.
LimogesAges 18 years+ - NCT07470658Enrolling by invitation
Surveillance after positive FIT and normal colonoscopy
This trial studies the best way to follow up with people who had a positive FIT stool test (high blood level) but a normal colonoscopy. It aims to find the right schedule for future screening to catch any problems early.
TaipeiAges 45–74 - NCT06831734Enrolling by invitation
Real-world safety study of Alhemo in hemophilia
This trial will track how well Alhemo works and how safe it is for people with hemophilia A or B in everyday use. If you are 12 or older and your doctor has already decided to start you on Alhemo, this study will collect information to help doctors better understand the medicine's real-world benefits and risks.
