Long-Term Safety Study of Oral Pirtobrutinib or Idelalisib in Adults With Previously Treated Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma

What this Trial Is About

This research aims to evaluate the long-term safety of pirtobrutinib in people who have previously been treated for chronic lymphocytic leukemia CLL or small lymphocytic lymphoma SLL. It offers continued access to the study drug or follow-up for participants who completed a prior related study LOXO-BTK-20020. The study is designed to observe and monitor safety outcomes over an extended period. Participants receive either pirtobrutinib or idelalisib orally as part of the study treatments. These medications are taken every four weeks. The study is expected to last about five years, allowing researchers to collect long-term safety data on these treatments in a parallel group setup. Throughout the study, participants will have regular visits to monitor their health and any treatment-related effects. Researchers will track the percentage of participants experiencing serious treatment-emergent adverse events. They will also observe overall survival from the original study enrollment. Safety monitoring will continue up to 30 days after the last dose or until new anticancer therapy begins, ensuring careful follow-up for each participant.
