Tirzepatide dosing strategy to manage side effects in obesity
This study tests a new medication called tirzepatide, given at carefully adjusted doses, to help people with obesity lose weight while reducing unwanted side effects. Tirzepatide is a newer injectable medicine that helps control appetite and blood sugar.
Kuwait CityAges 18–100 - NCT06618703Recruiting
Brain radiation in childhood: early hormone check
This study follows children who had brain radiation for cancer to check for early hormone changes. It aims to catch and treat any hormone problems sooner.
AngersAges 4–18 - NCT06729684Recruiting
Digital health program for breast cancer side effects
This study is testing a personalized digital health program to help breast cancer survivors manage side effects. It uses a smartphone app to track symptoms and offer support.
Seoul, Republic of KoreaAges 18–65 - NCT06752239RecruitingPhase 3
Optimizing radiation to protect thyroid in nasopharyngeal cancer
This trial tests a way to adjust radiation therapy to better protect the thyroid gland during treatment for nasopharyngeal carcinoma. It aims to reduce thyroid damage while still effectively treating the cancer.
Nanchang, JiangxiAges 18–70 - NCT06950073Recruiting
Second radiation treatment for lung cancer in the chest
This study tests whether giving a second course of radiation to the chest (called retreatment) can control lung cancer that has come back or a new cancer that started there. People who have already had radiation to their chest and are healthy enough for more may be eligible.
Aarhus, JutlandAges Any age - NCT07008716RecruitingPhase 3
Omitting CTV for primary tumor in limited-stage small cell lung cancer
This trial tests whether treating the main tumor alone, without the nearby lymph nodes, can work as well in limited-stage small cell lung cancer after initial chemotherapy. You may qualify if you have not had disease progression after 2-4 cycles of standard chemo and meet other health criteria.
Guangzhou, GuangdongAges 18–75 - NCT07029906Recruiting
Testing if beta-blocker side effects are due to expectations
This study tests whether some side effects from beta-blockers are caused by your expectations (the nocebo effect) rather than the drug itself. If you have heart failure and stopped a beta-blocker due to symptoms, this study may help understand your experience and potentially find better ways to manage it.
LondonAges 18 years+ - NCT07035002RecruitingPhase 1
PD-1 knockout TILs for advanced colorectal cancer
This trial tests a new therapy where immune cells (TILs) from your tumor are modified to fight cancer more effectively. It's for people with advanced colorectal cancer who can't get standard treatments.
Shanghai, None SelectedAges 18–70 - NCT07116213Recruiting
Shorter radiation after surgery for high-risk endometrial cancer
This trial studies a new type of radiation therapy (called online adaptive radiotherapy) given in shorter, higher daily doses after surgery for high-risk endometrial cancer. The goal is to see if this approach is safe and effective for reducing side effects while still controlling the cancer.
Beijing, Beijing MunicipalityAges 18–70 - NCT07215169Recruiting
Manual lymph drainage for head and neck lymphedema
This study tests whether manual lymph drainage, a gentle massage technique, can reduce swelling in the head and neck after radiation therapy for throat cancer. It may help people who have completed treatment within the last year.
