Brief Summary
This is a study for participants with a type of blood cancer called mantle cell lymphoma (MCL). The main purpose is to compare pirtobrutinib (LOXO-305) to other drugs that work in a similar way that have already been approved by the United States Food and Drug Administration (US FDA). Participation could last up to two years, and possibly longer, if the disease does not progress.
