( 2.5 ) 2.1 Overview of Dosage Determination Asthma, and Chronic Rhinosinusitis with Nasal Polyps, and IgE-Mediated Food Allergy Determine dosage of XOLAIR by serum total IgE level (IU/mL) measured before the start of treatment, and by body weight (kg). For patients with asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), and IgE-mediated food allergy, dosage determination should be based on the primary diagnosis for which XOLAIR is being prescribed. Adjust doses for significant changes in body weight during treatment. Refer to Tables 1 and 2 for the recommended dosage for treatment of asthma, Table 3 for treatment of CRSwNP, and Table 4 for treatment of IgE-mediated food allergy. Total IgE levels are elevated during treatment and remain elevated for up to one year after the discontinuation of treatment. Therefore, re-testing of IgE levels during XOLAIR treatment cannot be used as a guide for dose determination. Interruptions lasting less than one year: Dose based on serum IgE levels obtained at the initial dose determination. Interruptions lasting one year or more: Re-test total serum IgE levels for dose determination ( Table 1 or 2 for treatment of asthma, based on the patient's age, Table 3 for treatment of CRSwNP, and Table 4 for treatment of IgE-mediated food allergy). Chronic Spontaneous Urticaria Dosage of XOLAIR in patients with chronic spontaneous urticaria (CSU) is not dependent on serum IgE (free or total) level or body weight [see Dosage and Administration (2.5) ] . 2.2 Recommended Dosage for Asthma The recommended dosage for asthma is XOLAIR 75 mg to 375 mg by subcutaneous injection every 2 or 4 weeks based on serum total IgE level (IU/mL) measured before the start of treatment and by body weight (kg) [see Dosage and Administration (2.1) ] .

The 300 mg dose may be administered as one subcutaneous injection of 300 mg/2 mL or as two subcutaneous injections of 150 mg/mL. Dosing of XOLAIR in CSU patients is not dependent on serum IgE (free or total) level or body weight. Duration of Therapy The appropriate duration of therapy for CSU has not been evaluated. Periodically reassess the need for continued therapy. 2.6 Administration Overview Administer XOLAIR by subcutaneous injection. XOLAIR is intended for use under the guidance of a healthcare provider. Initiate therapy in a healthcare setting and once therapy has been safely established, the healthcare provider may determine whether self-administration of XOLAIR prefilled syringe or autoinjector by the patient or caregiver is appropriate, based on careful assessment of risk for anaphylaxis and mitigation strategies. Selection of Patients for Self-Administration of XOLAIR Prefilled Syringe or Autoinjector Healthcare providers should consider known risk factors for anaphylaxis to XOLAIR [see Warnings and Precautions (5.1) ] and mitigation strategies when selecting patients for self-administration. Patient-specific factors including the following criteria should be considered: 1a) Asthma, CRSwNP and CSU : Patient should have no prior history of anaphylaxis to XOLAIR or other agents, such as foods, drugs, biologics, etc. 1b) IgE-Mediated Food Allergy : Patient should have no prior history of anaphylaxis to XOLAIR or other agents (except foods), such as drugs, biologics, etc. 2) Patient should receive at least 3 doses of XOLAIR under the guidance of a healthcare provider with no hypersensitivity reactions 3) Patient or caregiver is able to recognize symptoms of anaphylaxis 4) Patient or caregiver is able to treat anaphylaxis appropriately 5) Patient or caregiver is able to perform subcutaneous injections with XOLAIR prefilled syringe or autoinjector with proper technique according to the prescribed dosing regimen and Instructions for Use 2.7 XOLAIR Prefilled Syringe and Autoinjector XOLAIR injection doses are available as a prefilled syringe or as an autoinjector. Instruct patients or caregivers to follow the directions provided in the " Instructions for Use " for preparation and administration of XOLAIR prefilled syringe or autoinjector [see Instructions for Use ] . XOLAIR Prefilled Syringe Adolescents 12 years of age and older: XOLAIR prefilled syringe may be self-administered under adult supervision. Pediatric Patients 1 to 11 years of age: XOLAIR prefilled syringe should be administered by a caregiver. XOLAIR Autoinjector Adolescents 12 years of age and older: XOLAIR autoinjector may be self-administered under adult supervision. The XOLAIR autoinjectors (all doses) are intended for use only in adults and adolescents aged 12 years and older. Pediatric Patients 1 to 11 years of age: The XOLAIR autoinjectors (all doses) are not intended for use in pediatric patients under 12 years of age. Administration Instructions for Prefilled Syringe and Autoinjector Persons with latex allergies should not handle XOLAIR prefilled syringe because the needle cap of the XOLAIR 75 mg/0.5 mL and 150 mg/mL prefilled syringes contains a derivative of natural rubber latex which may cause allergic reactions in latex sensitive individuals [see How Supplied/Storage and Handling (16) ] . Visually inspect the contents of the prefilled syringe or autoinjector for particulate matter and discoloration prior to administration. XOLAIR prefilled syringe or autoinjector solution should be clear and colorless to pale brownish yellow. Do not use the prefilled syringe or autoinjector if the medicine is cloudy, discolored, or contains particles. Determine the number of prefilled syringes or autoinjectors needed for patient's dosage (see Table 5 ). For pediatric patients 1 to 11 years of age, consideration should be given to the number of prefilled syringe injections needed and volume to be injected relative to the patient's bodyweight. For patients requiring more than 1 injection to complete a full dose, administer each injection at least 1 inch apart from other injection sites. Administer subcutaneous injection into the thigh or abdomen, avoiding the 2-inch (5 cm) area directly around the navel. The outer area of the upper arms may be used only if the injection is being given by a caregiver or healthcare provider [see Instructions for Use ] . The injection may take up to 15 seconds to administer. Table 5.

8.4 Pediatric Use Asthma Safety and effectiveness of XOLAIR for moderate to severe persistent asthma who had a positive skin test or in vitro reactivity to a perennial aeroallergen and whose symptoms are inadequately controlled with inhaled corticosteroids, have been established in pediatric patients aged 6 years and older. Use of XOLAIR for this indication is supported by evidence from adequate and well-controlled studies. XOLAIR was evaluated in 2 trials in 926 (XOLAIR 624; placebo 302) pediatric patients 6 to <12 years of age with moderate to severe persistent asthma who had a positive skin test or in vitro reactivity to a perennial aeroallergen. One trial was a pivotal trial of similar design and conduct to that of adult and adolescent Asthma Trials 1 and 2. The other trial was primarily a safety study and included evaluation of efficacy as a secondary outcome. In the pivotal trial, XOLAIR-treated patients had a statistically significant reduction in the rate of exacerbations (exacerbation was defined as worsening of asthma that required treatment with systemic corticosteroids or a doubling of the baseline ICS dose) [see Clinical Studies (14.1) ] . Safety and efficacy in pediatric patients with asthma below 6 years of age have not been established. Chronic Rhinosinusitis with Nasal Polyps Safety and effectiveness in pediatric patients with chronic rhinosinusitis with nasal polyps (CRSwNP) below 18 years of age have not been established. IgE-Mediated Food Allergy The safety and effectiveness of XOLAIR for the reduction of allergic reactions (Type I), including anaphylaxis, that may occur with accidental exposure to one or more foods have been established in pediatric patients aged 1 year and older with IgE-mediated food allergy. Use of XOLAIR for this indication is supported by evidence from an adequate and well-controlled study that included a total of 165 pediatric patients; 61 patients aged 1 year to less than 6 years of age and 104 patients aged 6 to less than 18 years of age. A significantly greater percentage of XOLAIR-treated patients compared to placebo-treated patients was able to consume a single dose of food (peanut, cashew, milk, egg) without dose- limiting symptoms [see Clinical Studies (14.3) ]. Safety and effectiveness in pediatric patients with IgE-mediated food allergy below 1 year of age have not been established. Chronic Spontaneous Urticaria The safety and effectiveness of XOLAIR for chronic spontaneous urticaria (CSU) who remain symptomatic despite H1 antihistamine treatment have been established in pediatric patients aged 12 years and older. Use of XOLAIR in this population is supported by evidence from adequate and well-controlled studies. Adolescent patients with CSU were evaluated in 39 patients 12 to 17 years of age (XOLAIR 29, placebo 10) included in three randomized, placebo-controlled CSU trials. A numerical decrease in weekly itch score was observed, and adverse reactions were similar to those reported in patients 18 years and older. Safety and effectiveness in pediatric patients with CSU below 12 years of age have not been established.
