This clinical trial is focused on studying a type of cancer known as soft tissue sarcoma. The treatment being tested combines a medication called Trabectedin with radiotherapy. Trabectedin is a drug that is administered through an intravenous infusion, which means it is given directly into the bloodstream through a vein. The purpose of the study is to find the best dose of Trabectedin that can be safely used with radiotherapy to treat patients with soft tissue sarcoma.
Participants in the study will receive the combination of Trabectedin and radiotherapy. The study will monitor how well the treatment works and any side effects that may occur. The goal is to determine the most effective and safe dose of Trabectedin when used with radiotherapy. The study will also look at how the treatment affects the cancer’s response and the chances of the cancer returning over a period of five years.
The study is divided into different groups, each receiving specific doses of Trabectedin to find the most suitable one. The researchers will collect information on how the cancer responds to the treatment and any side effects experienced by the participants. This information will help in understanding the best way to use Trabectedin with radiotherapy for treating soft tissue sarcoma.
