Primary Objective:

To compare progression-free survival (PFS) of LOXO-305 as monotherapy (Arm A) to investigator choice of covalent BTK inhibitor monotherapy (Arm B) in patients with previously treated mantle cell lymphoma (MCL)

Secondary Objectives:

To compare efficacy of LOXO-305 as monotherapy (Arm A) to investigator choice of covalent BTK inhibitor monotherapy (Arm B) treatment arms
To evaluate the safety and tolerability of each treatment arm
To evaluate the patient-reported outcomes

Eligibility
