Gut bacteria and CDK4/6 inhibitor treatment in breast cancer
This study looks at how gut bacteria affect response to a type of targeted therapy (CDK4/6 inhibitors) combined with hormone therapy in breast cancer that is hormone receptor-positive and HER2-negative. It may help find out why some people respond better to treatment and could lead to better personalized care.

Study of a new drug for advanced solid tumors

Scottsdale, ArizonaAges 18 years+ - NCT07459075RecruitingPhase 4
Bone graft with hormone for sinus lift before dental implants
This trial tests if adding parathyroid hormone to a bone graft improves bone growth in the upper jaw before placing dental implants. It may help people who have lost teeth and have very little bone in the sinus area.
BaghdadAges 18 years+ - NCT07446972Recruiting
Bariatric surgery and female sexual health study
This study looks at how weight-loss surgery (bariatric surgery) affects a woman's sexual function and hormone levels. It follows women who are already scheduled for surgery to see if their sexual health changes after the procedure.

Optimizing treatment for early HER2+ and triple-negative breast cancer
This trial aims to see if patients who had a complete response to chemo before surgery can safely stop or reduce their targeted therapy afterward. It includes people with early-stage HER2-positive or triple-negative breast cancer who had no cancer cells left in the tissue removed at surgery (a pathological complete response).
Houston, TexasAges 18 years+ - NCT07400419Recruiting
