^aThe incidence of treatment-related infusion-related reaction based on the single MedDRA preferred term is not listed

^bOccurred in the same patient

^cIncludes adverse events categorized as infusion-related reaction, drug hypersensitivity, or hypersensitivity reaction that occurred on the day of infusion or day after infusion, in addition to signs and symptoms of infusion-related reaction that occurred on the same day of infusion and resolved within 2 days (including adverse events classified by investigators as related or unrelated to treatment)
