CLL-11 Trial Design1: GAZYVA, in combination with chlorambucil, was evaluated in a Phase III, open-label, multicenter, 3-arm, randomized, parallel-group comparative study in patients with previously untreated CD20+ chronic lymphocytic leukemia and coexisting medical conditions and/or reduced renal function. Patients with creatinine clearance <30 mL/min or inadequate liver function were excluded. The primary endpoint was progression-free survival. Overall response rate and complete response rate were secondary endpoints. Enhanced response rates1 • GAZYVA + Clb more than doubled response rates vs Clb monotherapy (75.9% vs 32.1%, respectively) • More than 1 in 4 patients receiving GAZYVA + Clb achieved a complete response (27.8% vs 0.9%, respectively) The most common adverse reactions (incidence ≥10%) were: infusion reactions (69%), neutropenia (40%), thrombocytopenia (15%), anemia (12%), pyrexia (10%), cough (10%), and musculoskeletal disorders (17%)1 The most common Grade 3-4 adverse reactions were infusion reactions (21%), neutropenia (34%), and thrombocytopenia (11%)1 IMPORTANT SAFETY INFORMATION (CONT’D) Progressive Multifocal Leukoencephalopathy (PML) • JC virus infection resulting in PML, which can be fatal, was observed in patients treated with GAZYVA. Consider the diagnosis of PML in any patient presenting with new onset or changes to preexisting neurologic manifestations. Evaluation of PML includes, but is not limited to, consultation with a neurologist, brain MRI, and lumbar puncture. Discontinue GAZYVA therapy and consider discontinuation or reduction of any concomitant chemotherapy or immunosuppressive therapy in patients who develop PML with subsequent infusions. Symptoms may include hypotension, tachycardia, dyspnea, and respiratory symptoms (eg, bronchospasm, larynx and throat irritation, wheezing, laryngeal edema). Other common symptoms include nausea, vomiting, diarrhea, hypertension, flushing, headache, pyrexia, and chills • Premedicate patients with acetaminophen, antihistamine, and a glucocorticoid. Institute medical management for infusion reactions as needed. Closely monitor patients during the entire infusion. Infusion reactions within 24 hours of receiving GAZYVA have occurred Infusion Reactions • GAZYVA can cause severe and life-threatening infusion reactions. Two-thirds of patients experienced a reaction to the first 1000 mgs infused of GAZYVA. Infusion reactions can also occur Please see the following pages for additional Important Safety Information and brief summary of full Prescribing Information, including Boxed WARNINGS.
