This clinical trial is focused on studying a type of cancer called Follicular Lymphoma, which is a form of non-Hodgkin lymphoma. The study is evaluating the safety and effectiveness of a treatment that combines two medications: Mosunetuzumab and Lenalidomide. Mosunetuzumab is a medication that can be given either through an injection under the skin (subcutaneously) or directly into a vein (intravenously). Lenalidomide is taken orally in the form of capsules.
The purpose of the study is to determine the best dose of the combination treatment and to compare the two methods of administering Mosunetuzumab. The study will be conducted in two stages. In the first stage, participants will receive the combination of Mosunetuzumab and Lenalidomide to evaluate safety and determine the most suitable dose. In the second stage, participants will be randomly assigned to receive Mosunetuzumab either subcutaneously or intravenously, along with Lenalidomide, to further assess safety and how the body processes the drugs.
Throughout the study, researchers will monitor participants for any side effects and measure how the drugs are absorbed and processed by the body. The study aims to find out if the combination of Mosunetuzumab and Lenalidomide is a safe and effective treatment option for patients with Follicular Lymphoma.
