Feasibility of Combining the Phosphatidylinositol 3-Kinase Inhibitor Copanlisib With Rituximab-Based Immunochemotherapy in Patients With Relapsed Indolent B-cell Lymphoma.

ABSTRACT:

Background

When treating indolent B-cell lymphoma, combining continuously administered oral phosphatidylinositol 3-kinase (PI3K) inhibitors with immunochemotherapy has been associated with toxicity. CHRONOS-4 (Phase III; NCT02626455) investigates the intravenous, intermittently administered pan-class I PI3K inhibitor copanlisib in combination with rituximab plus bendamustine (R-B) or rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in patients with relapsed indolent B-cell lymphoma. We report safety run-in results.

Patients and methods

Patients aged ≥18 years with relapsed CD20-positive indolent B-cell lymphoma received copanlisib (45 mg, increasing to 60 mg if no dose-limiting toxicities) weekly on an intermittent schedule with R-B or R-CHO
