Summary
The overall purpose of this study is to evaluate the safety, efficacy, and durability of response of omalizumab in an open-label setting in adult participants with chronic rhinosinusitis with nasal polyps who completed the double-blind, placebo-controlled, Phase III studies GA39688 (NCT03280550) or GA39855 (NCT03280537). Participants will be eligible for enrollment in the study at, or within 28 days after, the Week 24 visit of Studies GA39688/GA39855. After enrollment into this open-label extension (OLE) study, participants will receive 28 weeks of dosing of omalizumab before entering a 24-week off-treatment observation phase of the study. Baseline in this OLE study is defined as the last pre-treatment measurement prior to randomization in Studies GA39688/GA39855 (i.e., baseline of Studies GA39688/GA39855). The data that will be reported from baseline to Week 24 inclusive will come from Studies GA39688/GA39855.
Eligibility Criteria
Inclusion Criteria
- Ability to comply with the study protocol, in the investigator's judgment

- For women of childbearing potential: agreement to remain abstinent or use acceptable contraceptive methods during the treatment period and for 60 days after the last dose of study drug
Exclusion Criteria
- Anaphylaxis/hypersensitivity related to study drug in Study GA39688 or GA39855
- Serious adverse events related to study drug in Study GA39688 or GA39855 that the investigator or Sponsor determines may jeopardize the patient's safety if he or she continues in the study
