A Comparison of Two Brief Suicide Prevention Interventions Tailored for Youth on the Autism Spectrum
Recruiting
Rates of suicide have increased significantly over the past two decades, particularly among youth.

Autistic individuals have identified suicide prevention as a top research priority; however, little is known about how to best help autistic youth at risk for suicide. The purpose of this study is to compare the effectiveness, feasibility, and acceptability... Read More

T-DM1 and Tucatinib Compared with T-DM1 Alone in Preventing Relapses in People with High Risk HER2-Positive Breast Cancer, the CompassHER2 RD Trial
Recruiting
This phase III trial studies how well trastuzumab emtansine (T-DM1) and tucatinib work in preventing breast cancer from coming back (relapsing) in patients with high risk, HER2 positive breast cancer. T-DM1 is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called DM1. Trastuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors, and delivers DM1 to kill them. Tucatinib may stop t... Read More
