2 DOSAGE AND ADMINISTRATION
2.1 Recommended Dosage
The recommended dosage of TEZSPIRE is 210 mg administered subcutaneously once every 4 weeks.
Missed Dose Information
If a dose is missed, administer the dose as soon as possible. Thereafter, the patient can continue (resume) dosing on the usual day of administration. If the next dose is already due, then administer as planned.
2.2 Preparation and Administration Instructions
TEZSPIRE vial and pre‑filled syringe are intended for administration by a healthcare provider.
TEZSPIRE pre-filled pen can be administered by patients/caregivers or healthcare providers. Patients/caregivers may administer TEZSPIRE pre-filled pen after proper training in subcutaneous injection technique and after the healthcare provider determines it is appropriate.
Each vial, pre-filled syringe and pre‑filled pen contain a single dose of TEZSPIRE.
•
Prior to administration, remove TEZSPIRE from the refrigerator and allow it to reach room temperature. This generally takes 60 minutes. Do not expose to heat and do not shake. Do not use if the security seal on the carton has been broken. Do not put back in the refrigerator once TEZSPIRE has reached room temperature.
•
Visually inspect TEZSPIRE for particulate matter and discoloration prior to administration. TEZSPIRE is a clear to opalescent, colorless to light yellow solution. Do not use TEZSPIRE if liquid is cloudy, discolored, or if it contains large particles or foreign particulate matter. Do not use if the vial, pre-filled syringe or pre‑filled pen has been dropped or damaged or if the expiration date has passed.
•
Inject TEZSPIRE 210 mg (contents of one vial, one pre-filled syringe or one pre-filled pen as described below) subcutaneously into the thigh or abdomen, except for the 2 inches (5 cm) around the navel. If a healthcare provider or caregiver administers the injection, the upper arm can also be used. A patient should not self-inject in the upper arm. TEZSPIRE should not be injected into areas where the skin is tender, bruised, erythematous, or hardened. It is recommended to rotate the injection site with each injection.
Administration Instructions for Single-Dose Pre-filled Syringe
Refer to Figure 1 to identify the pre-filled syringe components for use in the administration steps.
Do not remove the needle cover until Step 2 of these instructions when you are ready to inject TEZSPIRE. Do not touch the needle guard activation clips to prevent premature activation of the needle safety guard.
Figure 1 TEZSPIRE Pre-filled Syringe Components
|
Grasp the syringe body to remove the pre-filled syringe from its tray. Do not grab the pre-filled syringe by the plunger. The pre-filled syringe may contain small air bubbles; this is normal. Do not expel the air bubbles prior to administration. | |
|
|
Do not remove the needle cover until ready to inject. Hold the syringe body and remove the needle cover by pulling straight off. Do not hold the plunger or plunger head while removing the needle cover. You may see a drop of liquid at the end of the needle. This is normal. |
|
|
Gently pinch the skin and administer subcutaneously at approximately 45° angle into the recommended injection site (i.e., upper arm, thigh, or abdomen). |
|
|
Inject all of the medication by pushing in the plunger all the way until the plunger head is completely between the needle guard activation clips. This is necessary to activate the needle guard. |
|
|
After injection, maintain pressure on the plunger head and remove the needle from the skin. Release pressure on the plunger head to allow the needle guard to cover the needle. Do not re-cap the pre-filled syringe. |
|
Discard the used syringe into a sharps container. |
Administration Instructions for Single-Dose Pre-filled Pen
These administration instructions are intended for healthcare providers use only. Patients and caregivers should refer to the TEZSPIRE pre-filled pen ‘Instructions for Use’ for more detailed instructions on the preparation and administration of TEZSPIRE pre-filled pen [See Instructions for Use].

Do not touch the needle or push the orange needle guard with your finger. Do not put the cap back on the pre-filled pen. You could cause the injection to happen too soon or damage the needle. |
|
Gently pinch the skin at the injection site or give the injection without pinching the skin. Inject TEZSPIRE by following the steps into the recommended injection site (i.e., upper arm, thigh, or abdomen). When injecting, you will hear the first click that tells you the injection has started. Press and hold the pre-filled pen for 15 seconds until you hear the second click. Do not change the position of the pre-filled pen after the injection has started. | |
|
|
Position the pre-filled pen. Place the orange needle guard flat against the skin (90‑degree angle). Make sure you can see the viewing window. |
|
|
Press down firmly until you cannot see the orange needle guard. You will hear the first ‘click’, this tells you the injection has started. The orange plunger will move down in the viewing window during the injection. |
|
|
Hold down firmly for about 15 seconds. You will hear a second ‘click’, this tells you the injection has finished. The orange plunger will fill the viewing window. |
|
|
After you have completed the injection, lift the pre-filled pen straight up. The orange needle guard will slide down and lock into place over the needle. |
|
Discard the used pre-filled pen into a sharps container. |
CLINICAL STUDIES SECTION
14 CLINICAL STUDIES
The efficacy of TEZSPIRE was evaluated in two randomized, double-blind, parallel group, placebo-controlled clinical trials (PATHWAY [NCT02054130] and NAVIGATOR [NCT03347279]) of 52 weeks duration. The two trials enrolled a total of 1609 patients 12 years of age and older with severe asthma.
PATHWAY was a 52-week dose-ranging exacerbation trial that enrolled 550 adult patients with severe asthma who received treatment with tezepelumab-ekko 70 mg subcutaneously every 4 weeks, TEZSPIRE 210 mg subcutaneously every 4 weeks, tezepelumab-ekko 280 mg subcutaneously every 2 weeks, or placebo subcutaneously. Patients were required to have a history of 2 or more asthma exacerbations requiring oral or injectable corticosteroid treatment or 1 asthma exacerbation resulting in hospitalization in the past 12 months.
NAVIGATOR was a 52-week exacerbation trial that enrolled 1061 patients (adult and pediatric patients 12 years of age and older) with severe asthma who received treatment with TEZSPIRE 210 mg subcutaneously every 4 weeks or placebo subcutaneously every 4 weeks. Patients were required to have a history of 2 or more asthma exacerbations requiring oral or injectable corticosteroid treatment or resulting in hospitalization in the past 12 months.
In both PATHWAY and NAVIGATOR, patients were required to have an Asthma Control Questionnaire 6 (ACQ-6) score of 1.5 or more at screening and reduced lung function at baseline [pre-bronchodilator forced expiratory volume in 1 second (FEV1) below 80% predicted in adults, and below 90% predicted in adolescents]. Patients were required to have been on regular treatment with medium or high-dose inhaled corticosteroids (ICS) and at least one additional asthma controller, with or without oral corticosteroids (OCS). Patients continued background asthma therapy throughout the duration of the trials. In both trials, patients were enrolled without requiring a minimum baseline level of blood eosinophils or FeNO.
The demographics and baseline characteristics of PATHWAY and NAVIGATOR are provided in Table 2 below.

Exacerbations
The primary endpoint for PATHWAY and NAVIGATOR was the rate of clinically significant asthma exacerbations measured over 52 weeks. Clinically significant asthma exacerbations were defined as worsening of asthma requiring the use of or increase in oral or injectable corticosteroids for at least 3 days, or a single depo-injection of corticosteroids, and/or emergency department visits requiring use of oral or injectable corticosteroids and/or hospitalization.
In both PATHWAY and NAVIGATOR, patients receiving TEZSPIRE had significant reductions in the annualized rate of asthma exacerbations compared to placebo. There were also fewer exacerbations requiring emergency room visits and/or hospitalization in patients treated with TEZSPIRE compared with placebo (Table 3).

Patient Reported Outcomes
Changes from baseline in Asthma Control Questionnaire 6 (ACQ-6) and Standardized Asthma Quality of Life Questionnaire for ages 12 and older [AQLQ(S)+12] were also assessed as secondary endpoints in PATHWAY and NAVIGATOR. In both trials, more patients treated with TEZSPIRE compared to placebo had a clinically meaningful improvement in ACQ-6 and AQLQ(S)+12. Clinically meaningful improvement (responder rate) for both measures was defined as improvement in score of 0.5 or more at end of trial. In NAVIGATOR, the ACQ-6 responder rate for TEZSPIRE was 86% compared with 77% for placebo (OR=1.99; 95% CI 1.43, 2.76) and the AQLQ(S)+12 responder rate for TEZSPIRE was 78% compared with 72% for placebo (OR=1.36; 95% CI 1.02, 1.82). Similar findings were seen in PATHWAY.
Additional Trial
In a randomized, double-blind, parallel group, placebo-controlled clinical trial, the effect of TEZSPIRE (210 mg subcutaneously every 4 weeks) on reducing the use of maintenance OCS was evaluated. The trial enrolled 150 adult patients with severe asthma who required treatment with daily OCS (7.5 mg to 30 mg per day) in addition to regular use of high-dose ICS and a long- acting beta-agonist with or without additional controller(s). The primary endpoint was categorized percent reduction from baseline of the final OCS dose at Week 48 (≥90% reduction, ≥75% to <90% reduction, ≥50% to <75% reduction,
0% to <50 reduction, and no change or no decrease in OCS), while maintaining asthma control. TEZSPIRE did not demonstrate a statistically significant reduction in maintenance OCS dose compared with placebo (cumulative OR=1.28; 95% CI 0.69, 2.35).

Before using your TEZSPIRE pre-filled pen, your healthcare provider should show you or your caregiver how to use it the right way. Read this Instructions for Use before you start using your TEZSPIRE pre- filled pen and each time you get a refill. There may be new information. This information should not replace talking to your healthcare provider about your medical condition and your treatment. If you or your caregiver have any questions, talk to your healthcare provider. | |
Important information you need to know before injecting TEZSPIRE | |
Store TEZSPIRE in a refrigerator between 36°F to 46°F (2°C to 8°C) in its original carton until you are ready to use it. TEZSPIRE may be kept at room temperature between 68°F to 77˚F (20°C to 25°C) for a maximum of 30 days. Store TEZSPIRE in the original carton to protect it from light. When TEZSPIRE has reached room temperature,do not put it back in the refrigerator. Throw away (dispose of) TEZSPIRE that has been stored at room temperature for more than 30 days. | |
Do not use your TEZSPIRE pre-filled pen if: •
•
•
•
|
Do not: •
•
•
. |
If any of the above happens, throw away the pre-filled pen in a puncture- resistant (sharps) container and use a new TEZSPIRE pre-filled pen. Each TEZSPIRE pre-filled pen contains 1 dose of TEZSPIRE that can only be used 1 time. TEZSPIRE is given only as an injection under the skin (subcutaneous). Keep the TEZSPIRE pre-filled pen and all medicines out of the sight and reach of children. | |
Your TEZSPIRE pre-filled pen | |
Do not remove the cap until Step 6 of these instructions when you are ready to inject TEZSPIRE. | |
 | |
Preparing to inject TEZSPIRE Step 1 – Gather supplies | |
•
•
•
•
•
| |
| |
Step 2 – Prepare to use your TEZSPIRE pre-filled pen | |
Let TEZSPIRE come to room temperature between 68°F to 77˚F (20°C to 25°C) for about 60 minutes before giving the injection. Keep the pre-filled pen in its original carton to protect it from light. Do not warm the pre-filled pen in any other way. For example,do not warm it in a microwave or hot water, in direct sunlight, or near other heat sources. |
|
Do not put TEZSPIRE back in the refrigerator after it has reached room temperature. Throw away (dispose of) TEZSPIRE that has been stored at room temperature for more than 30 days. Do not remove the cap until Step 6. | |
Step 3 – Remove and check the pre-filled pen | |
Grab the middle of the pre-filled pen body to remove the pre-filled pen from its tray. Check the pre-filled pen for damage. Do not use the pre-filled pen if the pre-filled pen is damaged. Check the expiration date on the pre-filled pen.Do not use the pre- filled pen if the expiration date has passed. Look at the liquid through the viewing window. The liquid should be clear and colorless to light yellow. Do not inject TEZSPIRE if the liquid is cloudy, discolored, or contains large particles. You may see small air bubbles in the liquid. This is normal. You do not need to do anything about it. |
|
Injecting TEZSPIRE Step 4 – Choose an injection site | |
If you are giving yourself the injection, therecommended injection site is the front of your thigh or the lower part of your stomach (abdomen).Do not inject yourself in the arm. A caregiver may inject you in the upper arm, thigh, or abdomen. For each injection, choose a different site that is at least 1 inch (3 cm) away from where you last injected. Do not inject: •
•
•
•
|
|
Step 5 – Wash your hands and clean the injection site Wash your hands well with soap and water. Clean the injection site with an alcohol wipe in a circular motion. Let it air dry. Do not touch the cleaned area before injecting. Do not fan or blow on the cleaned area. | |
| |
Step 6 – Pull off the cap | |
Do not remove the cap until you are ready to inject. Hold the pre-filled pen body with 1 hand, and carefully pull the cap straight off with your other hand. Put the cap to the side and throw it away later. The orange needle guard is now exposed. The orange needle guard is there to prevent you from touching the needle. Do not touch the needle or push on the orange needle guard with your finger. Do not put the cap back on the pre-filled pen. You could cause the injection to happen too soon or damage the needle. |
|
Step 7 – Inject TEZSPIRE | |
Follow your healthcare provider’s instruction on how to inject. You can either gently pinch the skin at the injection site or give the injection without pinching the skin. Inject TEZSPIRE by following the steps in figuresa, b, c andd. When injecting, you will hear the first click that tells you the injection has started. Press and hold the pre-filled pen for 15 seconds until you hear the second click. Do not change the position of the pre-filled pen after the injection has started. |
|
Position the pre-filled pen. •
•
| |
| |
Step 8 – Check the viewing window Check the viewing window to make sure all the medicine has been injected. If the orange plunger rod does not fill the viewing window, you may not have received the full dose. If this happens or if you have any other concerns, contact your healthcare provider. | |
|
|
Step 9 – Check the injection site | |
There may be a small amount of blood or liquid where you injected. This is normal. Gently hold pressure over your skin with a cotton ball or gauze until the bleeding stops. Do not rub the injection site. If needed, cover the injection site with a small bandage. |
|
Disposing of TEZSPIRE Step 10 – Dispose of the used pre-filled pen safely | |
Each pre-filled pen contains a single dose of TEZSPIRE andcannot be used again.Do not put the cap back on the pre-filled pen. Put your used pre-filled pen and cap in asharps disposal container right away after use. Put other used supplies in your household trash. Do not throw away the pre-filled pen in your household trash. |
