LOXORET: Phase 1/2 Study of LOXO-292 (Selpercatinib) in Patients with Advanced RET-Altered Solid Tumors or Brain Tumors

About this study

This study will test the safety of an experimental drug treatment in children and adolescents with advanced solid tumors or brain and spinal cord tumors.

Many children with these tumors are helped by standard cancer treatments, such as chemotherapy, radiation and surgery. However, some children do not respond to treatment or their cancer comes back after therapy. This study is for children with these kinds of advanced tumors.

The drug in this clinical trial is designed to treat solid and brain tumors that have an abnormality in the RET gene. Genes tell the cells of our bodies how to grow, develop and function.

The name of the experimental drug is selpercatinib (LOXO-292). This study is the first time selpercatinib will be used in children.

Eligibility overview
