This clinical trial is focused on studying treatments for relapsed/refractory solid tumors in children and young adults. These are types of cancer that have returned or are not responding to standard treatments. The study involves the use of several medications, including Abemaciclib, which is also known by its code name LY2835219. This medication is being tested in combination with other drugs such as Irinotecan and Temozolomide. In one part of the study, Abemaciclib is combined with Irinotecan and Temozolomide, while in another part, it is combined with Temozolomide alone. Additionally, for patients with a specific type of cancer called neuroblastoma, Abemaciclib is combined with Dinutuximab, GM-CSF, Irinotecan, and Temozolomide.
The purpose of this study is to find the best dose of Abemaciclib when used with these other medications. The study is divided into different parts, each testing a different combination of drugs. Participants will receive the study medications either by mouth or through an infusion, which is a way of delivering medicine directly into the bloodstream. The study will monitor how the body responds to these treatments and will look for any side effects that might occur.
Throughout the study, participants will have regular check-ups to assess their health and the effectiveness of the treatment. The study aims to provide valuable information that could help improve treatment options for young patients with these challenging types of cancer. The trial is expected to continue until 2025, allowing researchers to gather comprehensive data on the safety and effectiveness of these drug combinations.
