Summary

This trial aims to see if a combination of pirtobrutinib and rituximab can be effective in treating newly diagnosed mantle cell lymphoma without the use of chemotherapy.

Who is the study for?

This trial is for people newly diagnosed with a type of cancer called Mantle Cell Lymphoma (MCL), specifically those who are considered low or intermediate risk and have not yet been treated. The specific eligibility criteria to join the study were not provided.

What is being tested?

The study is testing a combination of two drugs, Pirtobrutinib and Rituximab, in patients with MCL. It aims to find out if this chemotherapy-free treatment can control the disease effectively.

Group I: Cohort BExperimental Treatment2 Interventions

If participants test positive for MRD at the 24 month time point, participants will be in Cohort B and the participant will continue taking pirtobrutinib.

Group II: Cohort AExperimental Treatment2 Interventions
