This clinical trial is focused on studying the safety and tolerability of a medication called olaparib in children and adolescents with solid tumors. Solid tumors are a type of cancer that forms in the body’s tissues, such as bones, muscles, or organs. The study aims to understand how well olaparib is tolerated by young patients and to determine the appropriate dose for this age group. Olaparib is taken orally, either as a capsule or a tablet, and is being tested to see if it can be a safe treatment option for these patients.
Participants in this study will receive olaparib, and some may receive a placebo. The study will monitor the effects of the medication over time, including any side effects or changes in the participants’ health. The trial will also collect information on how the body processes olaparib, which is known as pharmacokinetics. This information will help researchers understand how the drug behaves in the body and how it might be used to treat solid tumors in children and adolescents.
The study is designed to include children and adolescents who have solid tumors that have returned or are not responding to standard treatments. These tumors may include types like osteosarcoma, rhabdomyosarcoma, and neuroblastoma, among others. The trial will involve regular check-ups and assessments to ensure the safety and well-being of the participants. The ultimate goal is to find a safe and effective treatment option for young patients with these challenging conditions.
