Step-by-step injection guide

Please review the steps detailed in the FDA-approved Instructions for Use. Afterward, you may use the following summary as a quick reference before injecting.
 

  • Do not use if the carton is damaged or appears to be tampered with
  • Do not open the carton until you are ready to inject
  • Do not use if the autoinjector has been damaged or appears to be tampered with
  • Do not take the cap off the autoinjector until you are ready to inject
  • Do not use if the autoinjector has been dropped on a hard surface or dropped after removing the needle cap
  • Do not take apart the autoinjector at any time
  • Do not clean or touch the needle guard
  1. Take the carton containing the autoinjector out of the refrigerator.
    • If you need more than 1 autoinjector to deliver your prescribed dose, take all cartons out of the refrigerator at the same time (each carton contains 1 autoinjector). The following steps must be followed for each autoinjector
  2. Check the expiration date on the back of the XOLAIR carton.
    • Do not use if the expiration date has passed
    • If the expiration date has passed, safely throw away the autoinjector in a sharps disposal container (see Step 15) and contact your healthcare provider
  3. Allow the autoinjector to reach room temperature.
    • Set aside the carton on a clean, flat surface for at least 30 to 45 minutes so the autoinjector can warm up on its own to room temperature. Leave the autoinjector in the carton to protect it from light
    • If the autoinjector does not reach room temperature, this could cause the injection to feel uncomfortable
    • Do not speed up the warming process using any heat sources such as warm water or a microwave
  4. Open the carton.
    • Wash your hands with soap and water
    • Take the autoinjector out of the carton as shown
    • Do not turn the carton upside down to take out the autoinjector, as this may damage the autoinjector
    • Do not hold the autoinjector by the cap. Make sure you hold the autoinjector by the middle
    • Do not remove the cap until you are ready to inject
  5. Check the autoinjector before use.
    • Look through the viewing window of the autoinjector. The medicine in the autoinjector viewing window should be clear and colorless to pale brownish-yellow. You may see air bubbles in the medicine, which is normal
    • Do not use the autoinjector if the medicine contains particles, or if the medicine looks cloudy or brown
    • Check the expiration date on the autoinjector. Do not use the autoinjector if the expiration date has passed
    • Do not use the autoinjector if it appears to be damaged or tampered with
    • If the medicine does not look as described or if the expiration date has passed, safely throw away the autoinjector in a sharps disposal container (see Step 15) and contact your healthcare provider
  6. Choose where to inject.
    • If giving yourself the injection, the injection sites are the front of your thigh or stomach area (abdomen). If a caregiver is giving the injection, the injection sites are the outer area of the upper arm, the front of the thigh or stomach area (abdomen). Do not try to inject yourself in the upper arm
    • Do not inject within the 2-inch area directly around your belly button (navel)
    • Do not inject into moles, scars, bruises, or areas where the skin is tender, red, hard, or if there are breaks in the skin
    • Do not inject through clothing. The injection site should be uncovered, clean skin
    • If your prescribed dose requires more than 1 injection, make sure your injections are at least 1 inch apart from each other
  7. Clean the injection site.
    • Wipe the injection site with an alcohol swab in a circular motion and let it air dry for 10 seconds
    • Do not fan or blow on the cleaned skin
    • Do not touch the injection site again before giving the injection
  1. Remove the cap.
    • Hold the autoinjector firmly with 1 hand and pull the cap straight off with your other hand. Do not twist the cap
    • Do not put the cap back on the autoinjector. Throw away the cap in regular household trash
    • Do not clean or touch the needle guard of the device
  2. Position the autoinjector.
    • Hold the autoinjector comfortably with the needle guard directly against the skin
    • The autoinjector should be at a 90-degree angle against the skin
  3. Start the injection.
    • Press straight down and hold the autoinjector firmly against the skin. The 1st click indicates that the injection has started
    • Hold the autoinjector tightly in place. Do not change the angle of injection or remove the autoinjector until the injection is completed
  4. Monitor injection using green indicator.
    • Keep holding the autoinjector against the skin. The green indicator will move within the viewing window
  5. Complete injection.
    • Listen for the 2nd click. This indicates that the injection is almost complete
    • Hold the autoinjector in position until the green indicator has stopped moving and completely fills the viewing window to make sure the injection is complete
  6. Remove from skin and check the green indicator.
    • After the green indicator has stopped moving and has completely filled the viewing window, lift the autoinjector straight up from the skin. The needle guard will automatically extend and lock over the needle
    • If the green indicator has not completely filled the viewing window, contact your healthcare provider or pharmacist
  7. Care for the injection site.
    • Do not rub the injection site
    • There may be a little bleeding or a drop of liquid at the injection site. You can press a cotton ball or gauze pad over the injection site until any bleeding stops
    • In case of skin contact with the medicine, wash the area that touched the medicine with water
    • If needed, cover the injection site with a small bandage

If your prescribed dose requires more than 1 injection:

  • Throw away the used autoinjector as described in Step 15
  • Repeat Step 2 through Step 14 for the next injection using a new autoinjector
  • Make sure each injection is at least 1 inch apart from each other
  • Complete all the required injections for your prescribed dose, immediately one after another. Contact your healthcare provider if you have any questions
  1. Throw away (dispose of) autoinjector.

    • The XOLAIR Autoinjector is a single-dose autoinjector and should not be used again
    • Do not throw away (dispose of) the autoinjectors in your household trash
    • Do not recap the autoinjector

If you do not have an FDA-cleared sharps disposal container, you may use a household container that is:

  • made of a heavy-duty plastic,
  • can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out,
  • upright and stable during use,
  • leak-resistant, and
  • properly labeled to warn of hazardous waste inside the container
  • When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used autoinjectors. For more information about safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA’s website at: http://www.fda.gov/safesharpsdisposal

Supplies needed to reconstitute the vial and administer XOLAIR
 

Products not shown actual size.

Once the correct dose has been determined and the necessary supplies have been assembled, you are ready to begin.
 

Step-by-step injection guide

Please review the steps detailed in the FDA-approved Instructions for Use. Afterward, you may use the following summary as a quick reference before injecting.
 

First, determine the number of vials you will need to reconstitute.
Each vial contains 150 mg of XOLAIR.

Step 1:

Remove the plastic cap from the XOLAIR vial.

Step 2:

Remove the plastic cap from the diluent vial containing Sterile Water for Injection (SWFI) USP.

Step 3:

Using an alcohol swab, wipe the rubber stopper of the XOLAIR vial and the diluent vial.

Step 1:

Draw 1.4 mL of SWFI, USP, into a 3-mL syringe equipped with a 1-inch, 18-gauge needle.

Step 2:

Place the XOLAIR vial upright on a flat surface and, using standard aseptic technique, insert the needle and inject the SWFI, USP, directly onto the product. Remove the syringe and needle from the vial.

Step 3:

Keeping the XOLAIR vial upright, gently swirl the vial for approximately 1 minute to evenly wet the powder. Do not shake.

Step 4:

Gently swirl the vial for 5 to 10 seconds approximately every 5 minutes in order to dissolve any remaining solids. The lyophilized product takes 15 to 20 minutes to dissolve. If it takes longer than 20 minutes to dissolve completely, gently swirl the vial for 5 to 10 seconds approximately every 5 minutes until there are no visible gel-like particles in the solution. Do not use if the contents of the vial do not dissolve completely by 40 minutes.

Step 1:

Invert the vial for 15 seconds in order to allow the solution to drain toward the stopper. Using a new 3-mL syringe equipped with a 1-inch, 18-gauge needle, insert the needle into the inverted vial. Position the needle tip at the very bottom of the solution in the vial stopper when drawing the solution into the syringe. The reconstituted product is somewhat viscous. Withdraw all the product from the vial before expelling any air or excess solution from the syringe. Before removing the needle from the vial, pull the plunger all the way back to the end of the syringe barrel in order to remove all of the solution from the inverted vial.

Step 2:

Replace the 18-gauge needle with a 25-gauge needle for subcutaneous injection.

Step 3:

Expel air, large bubbles, and any excess solution in order to obtain a volume of 1.2 mL corresponding to a dose of 150 mg of XOLAIR. To obtain a volume of 0.6 mL corresponding to a dose of 75 mg of XOLAIR, expel air and large bubbles, and discard 0.6 mL from the syringe. A thin layer of small bubbles may remain at the top of the solution in the syringe.

Step 1:

Selecting the injection site.

XOLAIR may be administered anywhere subcutaneous injections are typically given.

For patients requiring more than 1 injection per administration, it is important to choose a different injection site for each injection. This ensures that injections are limited to not more than 150 mg per site.

Step 2:

Prepare the injection site by swabbing it with alcohol.

Step 3:

Administer XOLAIR following your facility’s standard guidelines for subcutaneous injections.

Step 4:

Because the solution is somewhat viscous, the injection may take 5 to 10 seconds to administer.

XOLAIR is a viscous liquid. Due to the fluid’s thickness or resistance to flow, there may be added pressure when injecting.

Step 5:

When you are finished with administration, immediately discard syringes, needles, and remaining solution (if any) in a container designated for medical waste disposal, in compliance with state and federal regulations.

After reconstitution

After reconstitution, the XOLAIR solution is somewhat viscous and will appear clear or slightly opalescent. It is acceptable if there are a few small bubbles or foam around the edge of the vial; there should be no visible gel-like particles in the reconstituted solution. Do not use if foreign particles are present.

Stability after reconstitution

The solution should be used for subcutaneous administration within 8 hours following reconstitution when refrigerated in the vial at 2°C to 8°C (36°F to 46°F) or within 4 hours of reconstitution when stored at room temperature. Reconstituted XOLAIR vials should be protected from direct sunlight.

XOLAIR is for single use only and contains no preservatives.

Note: Each XOLAIR vial delivers 150 mg of XOLAIR per 1.2 mL upon reconstitution with 1.4 mL of sterile water for injection, USP.

XOLAIR shipping and storage

  • XOLAIR vial should be shipped at a controlled ambient temperature (≤30°C [≤86° F]) and stored under refrigerated conditions (2°C to 8°C [36° F to 46° F])
  • DO NOT use XOLAIR beyond the expiration date stamped on the carton. To learn more, read the administration instructions

If the XOLAIR prescribed for a labeled indication was spoiled or unable to be administered, the Genentech Spoilage Replacement Program might be able to provide you with a new supply.‡

‡Subject to certain limitations and conditions. The Spoilage Replacement Program covers infused or injected Genentech products.

Considering self-injection4

The choice is yours: You can offer self-injection for appropriate patients

When selecting patients or caregivers for self-injection, patient-specific factors including all of the following criteria should be considered:

Safety icon

The patient has no history of anaphylaxis

Patient should have no prior history of anaphylaxis to XOLAIR or other agents (except foods), such as drugs, biologics, etc

Medical necessity icon

The patient has initiated XOLAIR in-office

Patient has received at least 3 doses of XOLAIR under healthcare provider guidance and has displayed no hypersensitivity reactions

Dosing icon

The patient or caregiver has the required skills

  • Recognize symptoms of anaphylaxis
  • Treat anaphylaxis appropriately
  • Perform subcutaneous injections with the XOLAIR Autoinjector or prefilled syringe with proper technique according to the prescribed dosing regimen and Instructions for Use

Instruct patients or caregivers to follow the directions provided in the “Instructions for Use” for preparation and administration of XOLAIR Autoinjector or prefilled syringe

  • Adolescents 12 years of age and older: The XOLAIR Autoinjector or prefilled syringe may be self-administered under adult supervision
  • Pediatric patients 1 to 11 years of age: The XOLAIR prefilled syringe should be administered by a caregiver

XOLAIR self-injection is available for appropriate patients in all approved indications. The XOLAIR Autoinjector (all doses) is not intended for use in pediatric patients under 12 years of age.

Helping patients prepare for injection day

Learn about the injection

Remind patients to read the Medication Guide and Instructions for Use before every injection.

Discussing the injection process

Patients should know where the injection will be applied so they can wear clothes that offer easy access to the injection site.

What if they have a fear of needles?

If patients are receiving the injection in-office or by a caregiver, encourage them to focus their attention elsewhere with a game, book, or movie.

Models are for illustrative purposes. Individual results may vary.

Monitor for any reactions4

  • If you decide that the patient or a caregiver may be able to give the XOLAIR Autoinjector or prefilled syringe injections on their own, they should receive training on the right way to prepare and inject XOLAIR. They should not try to inject the XOLAIR Autoinjector or prefilled syringe until you show them the right way to give XOLAIR injections. They should use XOLAIR exactly as it’s prescribed
  • For adolescents 12 years of age and older, the XOLAIR Autoinjector or prefilled syringe may be self-administered under adult supervision
  • The XOLAIR Autoinjector is not intended for use in pediatric patients under 12 years of age
  • For pediatric patients 1 to 11 years of age, XOLAIR prefilled syringe should be administered by a caregiver
  • Patients or caregivers who are administering XOLAIR should have adequate at-home support
  • To help your patients prepare and inject XOLAIR, review the Instructions for Use with them

    IMPORTANT SAFETY INFORMATION

    INDICATION

    XOLAIR® (omalizumab) is indicated for:

    • Add-on maintenance treatment of chronic rhinosinusitis with nasal polyps (CRSwNP) in adult patients 18 years of age and older with inadequate response to nasal corticosteroids.

    WARNING: Anaphylaxis

    Anaphylaxis presenting as bronchospasm, hypotension, syncope, urticaria, and/or angioedema of the throat or tongue, has been reported to occur after administration of XOLAIR. Anaphylaxis has occurred as early as after the first dose of XOLAIR, but also has occurred beyond 1 year after beginning regularly administered treatment. Because of the risk of anaphylaxis, initiate XOLAIR therapy in a healthcare setting and closely observe patients for an appropriate period of time after XOLAIR administration. Health care providers administering XOLAIR should be prepared to manage anaphylaxis which can be life-threatening. Inform patients of the signs and symptoms of anaphylaxis and instruct them to seek immediate medical care should symptoms occur. Selection of patients for self-administration of XOLAIR should be based on criteria to mitigate risk from anaphylaxis.


    CONTRAINDICATIONS

    XOLAIR is contraindicated in patients with a severe hypersensitivity reaction to XOLAIR or to any ingredient of XOLAIR.

    WARNINGS AND PRECAUTIONS

    Anaphylaxis: Anaphylaxis has been reported to occur after administration of XOLAIR in premarketing clinical trials and in postmarketing spontaneous reports. In premarketing clinical trials in patients with asthma, anaphylaxis was reported in 3 of 3507 (0.1%) patients. Anaphylaxis occurred with the first dose of XOLAIR in two patients and with the fourth dose in one patient. The time to onset of anaphylaxis was 90 minutes after administration in two patients and 2 hours after administration in one patient.

    A case-control study in asthma patients showed that, among XOLAIR users, patients with a history of anaphylaxis to foods, medications, or other causes were at increased risk of anaphylaxis associated with XOLAIR, compared to those with no prior history of anaphylaxis.

    In postmarketing spontaneous reports, the frequency of anaphylaxis attributed to XOLAIR use was estimated to be at least 0.2% of patients based on an estimated exposure of about 57,300 patients from June 2003 through December 2006. Approximately 60% to 70% of anaphylaxis cases have been reported to occur within the first three doses of XOLAIR, with additional cases occurring sporadically beyond the third dose.

    Initiate XOLAIR only in a healthcare setting equipped to manage anaphylaxis which can be life-threatening. Observe patients closely for an appropriate period of time after administration of XOLAIR, taking into account the time to onset of anaphylaxis seen in premarketing clinical trials and postmarketing spontaneous reports. Inform patients of the signs and symptoms of anaphylaxis, and instruct them to seek immediate medical care should signs or symptoms occur.

    Once XOLAIR therapy has been established, administration of XOLAIR prefilled syringe or autoinjector outside of a healthcare setting by a patient or a caregiver may be appropriate for selected patients. Patient selection, determined by the healthcare provider in consultation with the patient, should take into account the pattern of anaphylaxis events seen in premarketing clinical trials and postmarketing spontaneous reports, as well as individual patient risk factors (e.g. prior history of anaphylaxis), ability to recognize signs and symptoms of anaphylaxis, and ability to perform subcutaneous injections with XOLAIR prefilled syringe or autoinjector with proper technique according to the prescribed dosing regimen and Instructions for Use.

    Discontinue XOLAIR in patients who experience a severe hypersensitivity reaction.

    Malignancy: Malignant neoplasms were observed in 20 of 4127 (0.5%) XOLAIR-treated patients compared with 5 of 2236 (0.2%) control patients in clinical studies of adults and adolescents (≥12 years of age) with asthma and other allergic disorders. The observed malignancies in XOLAIR-treated patients were a variety of types, with breast, non-melanoma skin, prostate, melanoma, and parotid occurring more than once, and five other types occurring once each. The majority of patients were observed for less than 1 year. The impact of longer exposure to XOLAIR or use in patients at higher risk for malignancy (e.g., elderly, current smokers) is not known.

    A subsequent 5-year observational study of 5007 XOLAIR-treated and 2829 non-XOLAIR-treated adolescent and adult patients with moderate to severe persistent asthma and a positive skin test reaction or in vitro reactivity to a perennial aeroallergen found that the incidence rates of primary malignancies (per 1000 patient years) were similar in both groups (12.3 vs 13.0, respectively). Study limitations which include the observational study design, the bias introduced by allowing enrollment of patients previously exposed to XOLAIR (88%), enrollment of patients (56%) while a history of cancer or a premalignant condition were study exclusion criteria, and the high study discontinuation rate (44%) preclude definitively ruling out a malignancy risk with XOLAIR.

    Acute Asthma Symptoms and Deteriorating Disease: XOLAIR has not been shown to alleviate asthma exacerbations acutely. Do not use XOLAIR to treat acute bronchospasm or status asthmaticus. Patients should seek medical advice if their asthma remains uncontrolled or worsens after initiation of treatment with XOLAIR.

    Corticosteroid Reduction: Do not discontinue systemic or inhaled corticosteroids abruptly upon initiation of XOLAIR therapy for asthma or CRSwNP. Decrease corticosteroids gradually under the direct supervision of a physician.

    Eosinophilic Conditions: In rare cases, patients with asthma on therapy with XOLAIR may present with serious systemic eosinophilia, sometimes presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome. These events usually, but not always, have been associated with the reduction of oral corticosteroid therapy. Physicians should be alert to eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy presenting in their patients. A causal association between XOLAIR and these underlying conditions has not been established.

    Fever, Arthralgia, and Rash: In post-approval use, some patients have experienced a constellation of signs and symptoms, including arthritis/arthralgia, rash, fever, and lymphadenopathy with an onset 1 to 5 days after the first or subsequent injections of XOLAIR. These signs and symptoms have recurred after additional doses in some patients. Physicians should stop XOLAIR if a patient develops this constellation of signs and symptoms.

    Parasitic (Helminth) Infection: Monitor patients at high risk of geohelminth infection while on XOLAIR therapy. Insufficient data are available to determine the length of monitoring required for geohelminth infections after stopping XOLAIR treatment.

    Laboratory Tests: Due to formation of XOLAIR:IgE complexes, serum total IgE levels increase following administration of XOLAIR and may remain elevated for up to 1 year following discontinuation of XOLAIR. Do not use serum total IgE levels obtained less than 1 year following discontinuation to reassess the dosing regimen for asthma or CRSwNP patients, because these levels may not reflect steady state free IgE levels.

    Potential Medication Error Related to Emergency Treatment of Anaphylaxis
    XOLAIR should not be used for the emergency treatment of allergic reactions, including anaphylaxis. In studies to simulate use, some patients and caregivers did not understand that XOLAIR is not intended for the emergency treatment of allergic reactions, including anaphylaxis. The safety and effectiveness of XOLAIR for emergency treatment of allergic reactions, including anaphylaxis, have not been established. Instruct patients that XOLAIR is for maintenance use to reduce allergic reactions, including anaphylaxis, while avoiding food allergens.

    ADVERSE REACTIONS

    Chronic Rhinosinusitis with Nasal Polyps: The most common adverse reactions (≥3% in XOLAIR-treated patients) included: headache (8.1%), injection site reaction (5.2%), arthralgia (3.0%), upper abdominal pain (3.0%), and dizziness (3.0%).

    Injection Site Reactions: Injection site reactions occurred at a rate of 5.2% in XOLAIR-treated patients compared with 1.5% in placebo-treated patients. Injection site reactions were mild to moderate severity and none resulted in study discontinuation.

    Injection Site Reactions in Healthy Adults: In an open label trial in healthy adults, in which the 300 mg/2 mL autoinjector was compared to the 300 mg/2 mL prefilled syringe, injection site reactions (e.g., induration, pain, erythema, hemorrhage, swelling, discomfort, bruising, hypoesthesia, edema, pruritus) were observed in 24% (16/66) of subjects treated with the autoinjector compared with 14% (9/64) of subjects treated with the prefilled syringe.

    Cardiovascular and Cerebrovascular Events from Clinical Studies in Patients with Asthma: A 5-year observational study was conducted in 5007 XOLAIR-treated and 2829 non-XOLAIR-treated patients ≥12 years of age for a different indication to evaluate the long term safety of XOLAIR, including the risk of malignancy. The results suggest a potential increased risk of serious cardiovascular and cerebrovascular events in patients treated with XOLAIR, however the observational study design, the inclusion of patients previously exposed to XOLAIR (88% for a mean of 8 months), baseline imbalances in cardiovascular risk factors between the treatment groups, an inability to adjust for unmeasured risk factors, and the high study discontinuation rate (44%) limit the ability to quantify the magnitude of the risk.

    Pregnancy: Data with XOLAIR use in pregnant women are insufficient to inform on drug associated risk.

Health care providers administering XOLAIR should be prepared to manage anaphylaxis which can be life-threatening. Inform patients of the signs and symptoms of anaphylaxis and instruct them to seek immediate medical care should symptoms occur. Selection of patients for self-administration of XOLAIR should be based on criteria to mitigate risk from anaphylaxis.

    INDICATION

    XOLAIR® (omalizumab) is indicated for:

    • Add-on maintenance treatment of chronic rhinosinusitis with nasal polyps (CRSwNP) in adult patients 18 years of age and older with inadequate response to nasal corticosteroids.


    CONTRAINDICATIONS

    XOLAIR is contraindicated in patients with a severe hypersensitivity reaction to XOLAIR or to any ingredient of XOLAIR.

    WARNINGS AND PRECAUTIONS

    Anaphylaxis: Anaphylaxis has been reported to occur after administration of XOLAIR in premarketing clinical trials and in postmarketing spontaneous reports. In premarketing clinical trials in patients with asthma, anaphylaxis was reported in 3 of 3507 (0.1%) patients. Anaphylaxis occurred with the first dose of XOLAIR in two patients and with the fourth dose in one patient. The time to onset of anaphylaxis was 90 minutes after administration in two patients and 2 hours after administration in one patient.

    A case-control study in asthma patients showed that, among XOLAIR users, patients with a history of anaphylaxis to foods, medications, or other causes were at increased risk of anaphylaxis associated with XOLAIR, compared to those with no prior history of anaphylaxis.

    In postmarketing spontaneous reports, the frequency of anaphylaxis attributed to XOLAIR use was estimated to be at least 0.2% of patients based on an estimated exposure of about 57,300 patients from June 2003 through December 2006. Approximately 60% to 70% of anaphylaxis cases have been reported to occur within the first three doses of XOLAIR, with additional cases occurring sporadically beyond the third dose.

    Initiate XOLAIR only in a healthcare setting equipped to manage anaphylaxis which can be life-threatening. Observe patients closely for an appropriate period of time after administration of XOLAIR, taking into account the time to onset of anaphylaxis seen in premarketing clinical trials and postmarketing spontaneous reports. Inform patients of the signs and symptoms of anaphylaxis, and instruct them to seek immediate medical care should signs or symptoms occur.

    Once XOLAIR therapy has been established, administration of XOLAIR prefilled syringe or autoinjector outside of a healthcare setting by a patient or a caregiver may be appropriate for selected patients. Patient selection, determined by the healthcare provider in consultation with the patient, should take into account the pattern of anaphylaxis events seen in premarketing clinical trials and postmarketing spontaneous reports, as well as individual patient risk factors (e.g. prior history of anaphylaxis), ability to recognize signs and symptoms of anaphylaxis, and ability to perform subcutaneous injections with XOLAIR prefilled syringe or autoinjector with proper technique according to the prescribed dosing regimen and Instructions for Use.

    Discontinue XOLAIR in patients who experience a severe hypersensitivity reaction.

    Malignancy: Malignant neoplasms were observed in 20 of 4127 (0.5%) XOLAIR-treated patients compared with 5 of 2236 (0.2%) control patients in clinical studies of adults and adolescents (≥12 years of age) with asthma and other allergic disorders. The observed malignancies in XOLAIR-treated patients were a variety of types, with breast, non-melanoma skin, prostate, melanoma, and parotid occurring more than once, and five other types occurring once each. The majority of patients were observed for less than 1 year. The impact of longer exposure to XOLAIR or use in patients at higher risk for malignancy (e.g., elderly, current smokers) is not known.

    A subsequent 5-year observational study of 5007 XOLAIR-treated and 2829 non-XOLAIR-treated adolescent and adult patients with moderate to severe persistent asthma and a positive skin test reaction or in vitro reactivity to a perennial aeroallergen found that the incidence rates of primary malignancies (per 1000 patient years) were similar in both groups (12.3 vs 13.0, respectively). Study limitations which include the observational study design, the bias introduced by allowing enrollment of patients previously exposed to XOLAIR (88%), enrollment of patients (56%) while a history of cancer or a premalignant condition were study exclusion criteria, and the high study discontinuation rate (44%) preclude definitively ruling out a malignancy risk with XOLAIR.

    Acute Asthma Symptoms and Deteriorating Disease: XOLAIR has not been shown to alleviate asthma exacerbations acutely. Do not use XOLAIR to treat acute bronchospasm or status asthmaticus. Patients should seek medical advice if their asthma remains uncontrolled or worsens after initiation of treatment with XOLAIR.

    Corticosteroid Reduction: Do not discontinue systemic or inhaled corticosteroids abruptly upon initiation of XOLAIR therapy for asthma or CRSwNP. Decrease corticosteroids gradually under the direct supervision of a physician.

    Eosinophilic Conditions: In rare cases, patients with asthma on therapy with XOLAIR may present with serious systemic eosinophilia, sometimes presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome. These events usually, but not always, have been associated with the reduction of oral corticosteroid therapy. Physicians should be alert to eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy presenting in their patients. A causal association between XOLAIR and these underlying conditions has not been established.

    Fever, Arthralgia, and Rash: In post-approval use, some patients have experienced a constellation of signs and symptoms, including arthritis/arthralgia, rash, fever, and lymphadenopathy with an onset 1 to 5 days after the first or subsequent injections of XOLAIR. These signs and symptoms have recurred after additional doses in some patients. Physicians should stop XOLAIR if a patient develops this constellation of signs and symptoms.

    Parasitic (Helminth) Infection: Monitor patients at high risk of geohelminth infection while on XOLAIR therapy. Insufficient data are available to determine the length of monitoring required for geohelminth infections after stopping XOLAIR treatment.

    Laboratory Tests: Due to formation of XOLAIR:IgE complexes, serum total IgE levels increase following administration of XOLAIR and may remain elevated for up to 1 year following discontinuation of XOLAIR. Do not use serum total IgE levels obtained less than 1 year following discontinuation to reassess the dosing regimen for asthma or CRSwNP patients, because these levels may not reflect steady state free IgE levels.

    Potential Medication Error Related to Emergency Treatment of Anaphylaxis
    XOLAIR should not be used for the emergency treatment of allergic reactions, including anaphylaxis. In studies to simulate use, some patients and caregivers did not understand that XOLAIR is not intended for the emergency treatment of allergic reactions, including anaphylaxis. The safety and effectiveness of XOLAIR for emergency treatment of allergic reactions, including anaphylaxis, have not been established. Instruct patients that XOLAIR is for maintenance use to reduce allergic reactions, including anaphylaxis, while avoiding food allergens.

    ADVERSE REACTIONS

    Chronic Rhinosinusitis with Nasal Polyps: The most common adverse reactions (≥3% in XOLAIR-treated patients) included: headache (8.1%), injection site reaction (5.2%), arthralgia (3.0%), upper abdominal pain (3.0%), and dizziness (3.0%).

    Injection Site Reactions: Injection site reactions occurred at a rate of 5.2% in XOLAIR-treated patients compared with 1.5% in placebo-treated patients. Injection site reactions were mild to moderate severity and none resulted in study discontinuation.

    Injection Site Reactions in Healthy Adults: In an open label trial in healthy adults, in which the 300 mg/2 mL autoinjector was compared to the 300 mg/2 mL prefilled syringe, injection site reactions (e.g., induration, pain, erythema, hemorrhage, swelling, discomfort, bruising, hypoesthesia, edema, pruritus) were observed in 24% (16/66) of subjects treated with the autoinjector compared with 14% (9/64) of subjects treated with the prefilled syringe.

    Cardiovascular and Cerebrovascular Events from Clinical Studies in Patients with Asthma: A 5-year observational study was conducted in 5007 XOLAIR-treated and 2829 non-XOLAIR-treated patients ≥12 years of age for a different indication to evaluate the long term safety of XOLAIR, including the risk of malignancy. The results suggest a potential increased risk of serious cardiovascular and cerebrovascular events in patients treated with XOLAIR, however the observational study design, the inclusion of patients previously exposed to XOLAIR (88% for a mean of 8 months), baseline imbalances in cardiovascular risk factors between the treatment groups, an inability to adjust for unmeasured risk factors, and the high study discontinuation rate (44%) limit the ability to quantify the magnitude of the risk.

    Pregnancy: Data with XOLAIR use in pregnant women are insufficient to inform on drug associated risk.
