In the Phase III CHRONOS-4 safety run-in, 21 patients received intravenous copanlisib plus rituximab-based immunochemotherapy. There were no dose-limiting toxicities, and preliminary objective response rates were 90% to 100%. Copanlisib is the first PI3K inhibitor to demonstrate safe, tolerable, and effective combinability with immunochemotherapy, with evaluation ongoing. Backgr...
