Description: Researchers are conducting a phase 3 global, randomized, open-label study comparing LOXO-305 to investigator’s choice of ibrutinib, acalabrutinib, or zanubrutinib in patients with mantle cell lymphoma who have received 1 or more lines of therapy and are Bruton tyrosine kinase (BTK) inhibitor-naive. The primary outcome measure of the trial is to compare progression-free survival after the administration of LOXO-305 as monotherapy compared with investigator’s choice of covalent BTK inhibitor monotherapy in patients with previously treated mantle cell lymphoma. Secondary outcome measures include the comparison of event-free survival and time to treatment failure between treatment arms and time to worsening of mantle cell lymphoma-related symptoms.
