Incidence of infusion reactions in the CLL-11 trial

Infusion-related reactions (IRRs) with GAZYVA (obinutuzumab) may be severe and life threatening and can occur at any time 1

  • Symptoms may include hypotension, tachycardia, dyspnea, and respiratory symptoms (eg, bronchospasm, larynx and throat irritation, wheezing, laryngeal edema)
  • Most frequently reported symptoms include nausea, fatigue, dizziness, vomiting, diarrhea, hypertension, flushing, headache, pyrexia, and chills

First 1000 mg infused: 65% of patients experienced IRRs with GAZYVA 1

  • Grade 3 or 4 reactions occurred in 20% of patients

Subsequent infusions: IRRs also occurred 1

  • The incidence of IRRs with subsequent infusions was 3% with the second 1000 mg and <1% thereafter
  • There were no Grade 3 or 4 IRRs reported after the first 1000 mg infused

GAZYVA CLL-11 Incidence of Infusion Reactions by Cycle Chart

Protocol modifications were implemented to help mitigate infusion-related reactions 1

  • Protocol modifications in CLL-11 required premedication with a corticosteroid* an antihistamine, and acetaminophen. The first 1000 mg dose was also divided into two infusions (100 mg on Day 1 and 900 mg on Day 2)
BEFORE PROTOCOL MODIFICATIONS (n=53)
AFTER PROTOCOL MODIFICATIONS (n=140)
89% of patients experienced an infusion-related reaction 53% of patients experienced an infusion-related reaction with the first 1000 mg and <3% thereafter

*Hydrocortisone is not recommended as it has not been effective in reducing the rate of infusion-related reactions.

  • In the rituximab product + Clb arm (n=321), the incidence of IRRs during Cycle 1 was 27% (24% Grades 1-2, 3% Grades 3-4) 7
    • In Cycle 2, the incidence of IRRs was 13% (12% Grades 1-2, 1% Grades 3-4)
    • The incidence of IRRs was 6% for Cycle 3, 2% for Cycle 4, 2% for Cycle 5, and 1% for Cycle 6
    • <1% of the rituximab product treated arm discontinued therapy due to an IRR
