Xolair Use in an 11-Year-Old Patient: Coverage and FDA Approval Status
The current FDA-approved prescribing information for Xolair now permits use in pediatric patients starting at age 6 years for asthma, making continued treatment in this 11-year-old patient fully within the approved indication and not experimental/investigational. 1
Current FDA-Approved Age Indications
The FDA label for omalizumab has evolved significantly since initial approval:
- For asthma: Xolair is FDA-approved for patients ≥6 years of age with moderate-to-severe persistent allergic asthma inadequately controlled with inhaled corticosteroids 1
- The original approval was limited to patients ≥12 years, but the pediatric indication was expanded to include children aged 6-11 years by the FDA in 2016 2
- The European Medicines Agency approved the pediatric indication (≥6 years) earlier in 2009 2
Clinical Evidence Supporting Pediatric Use
Robust clinical trial data supports efficacy and safety in the 6-11 year age group:
- Asthma Trial 4 (n=628 children aged 6 to <12 years) demonstrated that omalizumab significantly reduced asthma exacerbations over 24 weeks (rate ratio 0.69; 95% CI: 0.53,0.90) and over 52 weeks (rate ratio 0.57; 95% CI: 0.45,0.72) 1
- Asthma Trial 5 (n=298 children aged 6 to <12 years) showed similar reductions in exacerbations during both the 16-week fixed steroid period (rate ratio 0.58; 95% CI: 0.35,0.96) and 28-week treatment period (rate ratio 0.50; 95% CI: 0.36,0.71) 1
- These trials formed the basis for FDA approval in the pediatric population 2
Administration Considerations for This Age Group
For an 11-year-old patient, specific administration guidelines apply:
- The prefilled syringe should be administered by a caregiver for patients 1-11 years of age 1
- The autoinjector formulation is not intended for use in patients under 12 years of age 1
- For pediatric patients requiring multiple injections, consideration should be given to the number of injections and volume relative to body weight 1
Coverage Determination
This patient's continued treatment should be covered as it falls within the FDA-approved indication:
- The patient was appropriately authorized at age 10, which is within the approved age range of ≥6 years 1
- Continuation at age 11 remains fully within the approved pediatric indication 1
- The statement that "prescribing information states it may be given to adolescents starting at age 12" appears to reference outdated labeling information that predates the 2016 FDA approval expansion 2
Common Pitfall to Avoid
The key error here is relying on outdated prescribing information. The original FDA approval was indeed limited to patients ≥12 years 3, 4, but this was expanded in 2016 based on compelling pediatric trial data 2. Insurance denials based on the age 12 threshold are referencing superseded labeling and should be appealed with current FDA prescribing information 1.
