Grade 3/4 adverse reactions were: neutropenia (33%), infusion reactions (20%), thrombocytopenia (10%), anemia (4%), leukopenia (4%), diarrhea (2%), urinary tract infection (1%), pyrexia (<1%), and nasopharyngitis (<1%)1,2 • The most common adverse reactions (incidence ≥10%) were: infusion reactions (66%), neutropenia (38%), thrombocytopenia (14%), nausea (12%), anemia (11%), pyrexia (10%), cough (10%), and diarrhea (10%) IMPORTANT SAFETY INFORMATION (CONT’D) Infusion Reactions • GAZYVA can cause severe and life-threatening infusion • For patients with Grade 1, 2, or 3 infusion reactions: Interrupt reactions. Two-thirds of patients experienced a reaction to GAZYVA for Grade 3 reactions until resolution of symptoms. the first 1000 mg infused of GAZYVA. Infusion reactions can Interrupt or reduce the rate of the infusion for Grade 1 or 2 also occur with subsequent infusions. Symptoms may include reactions and manage symptoms hypotension, tachycardia, dyspnea, and respiratory symptoms (eg, bronchospasm, larynx and throat irritation, wheezing, Please see the following pages for additional Important and laryngeal edema). Other common symptoms include Safety Information and brief summary of full Prescribing nausea, vomiting, diarrhea, hypertension, flushing, headache, Information, including Boxed WARNINGS. pyrexia, and chills • Premedicate patients with acetaminophen, an 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 • For patients with any Grade 4 infusion reactions, including but not limited to anaphylaxis, acute life-threatening respiratory symptoms, or other life-threatening infusion reaction: Stop the GAZYVA infusion. Permanently discontinue GAZYVA therapy
