6 Adverse Reactions

6.1 Clinical Trials Experience

Additions and/or revisions underlined:

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Adverse Reactions in Adult and Pediatric Patients 12 Years of Age and Older with Asthma

The safety of TEZSPIRE in asthma was based on the pooled safety population from PATHWAY and NAVIGATOR, which consists of 665 adult and pediatric patients 12 years of age and older with severe asthma who received at least one dose of TEZSPIRE 210 mg subcutaneously once every 4 weeks. The two placebo-controlled clinical trials were of 52 weeks duration. In addition, a similar safety profile was seen in a trial that enrolled 150 adult patients with severe asthma who required treatment with daily oral corticosteroids [see Clinical Studies (14.1)].

Adverse reactions that occurred at an incidence greater than or equal to 3% and more common than in the placebo group from the pooled safety population (PATHWAY and NAVIGATOR) are shown in Table 1.

Adverse Reactions in Adult Patients with Chronic Rhinosinusitis with Nasal Polyps

The safety of TEZSPIRE in CRSwNP was based on WAYPOINT, a randomized, double-blind, parallel group, multicenter, placebo-controlled trial of 52 weeks duration, which consisted of 203 adult patients aged 18 years and older on standard of care treatment for CRSwNP who received at least one dose of TEZSPIRE 210 mg subcutaneously once every 4 weeks [see Clinical Studies (14.2)].

Adverse reactions that occurred at an incidence greater than or equal to 3% and more common than in the placebo group from the safety population (WAYPOINT) are shown in Table 2.

8 Use in Specific Populations

8.4 Pediatric Use

Additions and/or revisions underlined:

Asthma

The safety and effectiveness of TEZSPIRE for the add-on maintenance treatment of severe asthma have been established in pediatric patients aged 12 years and older [see Adverse Reactions (6.1) and Clinical Studies (14.1)]. Use of TEZSPIRE for this indication is supported by evidence from a total of 82 pediatric patients aged 12 to 17 years enrolled in NAVIGATOR and received treatment with TEZSPIRE 210 mg subcutaneously every 4 weeks (n=41) or placebo (n=41). Compared with placebo, improvements in annualized asthma exacerbation (rate ratio 0.70; 95% CI 0.34, 1.46) and FEV1 (LS mean change versus placebo 0.17 L; 95% CI -0.01, 0.35) were observed in pediatric patients treated with TEZSPIRE. The safety profile and pharmacodynamic responses in pediatric patients were generally similar to the overall study population.

The safety and effectiveness of TEZSPIRE have not been established in patients younger than 12 years of age with asthma.

CRSwNP

The safety and effectiveness of TEZSPIRE for the add-on maintenance treatment of inadequately controlled CRSwNP have been established in pediatric patients aged 12 years and older. Use of TEZSPIRE for this indication is supported by evidence from the adequate and well-controlled study of TEZSPIRE in adults (WAYPOINT) [see Clinical Studies (14.2)] with the following additional data:

  • Pharmacokinetic (PK) data from adult and pediatric patients aged 12 years and older with severe asthma and adult patients with CRSwNP [see Clinical Pharmacology (12.3)].
  • Safety data in pediatric patients aged 12 years and older with severe asthma [see Adverse Reactions (6.1)].

The safety and effectiveness of TEZSPIRE have not been established in patients younger than 12 years of age with CRSwNP.

8.5 Geriatric Use

Additions and/or revisions underlined:

Asthma

Of the 665 patients with asthma treated with TEZSPIRE in clinical trials (PATHWAY and NAVIGATOR) for severe asthma, 119 patients (18%) were 65 years or older. No overall differences in safety or effectiveness of TEZSPIRE have been observed between patients 65 years of age and older and younger patients [see Adverse Reactions (6.1) and Clinical Studies (14.1)].

CRSwNP

Of the 203 patients with CRSwNP treated with TEZSPIRE in a clinical trial (WAYPOINT) for CRSwNP, 29 patients (14%) were 65 years or older. No overall differences in safety or effectiveness of TEZSPIRE have been observed between patients 65 years of age and older and younger adult patients [see Adverse Reactions (6.1) and Clinical Studies (14.2)].

PATIENT INFORMATION

Additions and/or revisions underlined:

What is TEZSPIRE?

TEZSPIRE is a prescription medicine used:

  • with other asthma medicines for the maintenance treatment of severe asthma in people 12 years of age and older whose asthma is not controlled with their current asthma medicine.
  • with other medicines for the maintenance treatment of chronic rhinosinusitis with nasal polyps (CRSwNP) in people 12 years of age and older whose CRSwNP is not controlled with their current CRSwNP medicine.

TEZSPIRE helps:

  • prevent severe asthma attacks (exacerbations) and can improve your breathing.
  • reduce the size of your polyps, improve symptoms i.e. nasal congestion and loss of smell, and reduce the need for oral corticosteroids and surgery for your nasal polyps.

TEZSPIRE is not used to treat sudden breathing problems. Tell your healthcare provider if your asthma does not get better or if it gets worse after you start treatment with TEZSPIRE.

It is not known if TEZSPIRE is safe and effective in children under 12 years of age for the treatment of asthma.

It is not known if TEZSPIRE is safe and effective in children under 12 years of age for the treatment of CRSwNP.

. . .

Do not change or stop your other medicines, including corticosteroid medicines or other asthma medicines unless your healthcare provider tells you to. This may cause other symptoms that were controlled by those medicines to come back.

How should I use TEZSPIRE?

. . .

  • Do not try to inject TEZSPIRE until you or your caregiver have been shown the right way by your healthcare provider.

. . .

The most common side effects of TEZSPIRE include:

  • sore throat (pharyngitis)
  • joint pain (arthralgia)
  • back pain
  • common cold symptoms (nasopharyngitis)
  • upper respiratory tract infections
  • nose bleeds

6 Adverse Reactions

6.1 Clinical Trials Experience

Additions and/or revisions underlined:

Specific Adverse Reactions

Cardiovascular EventsIn a randomized, double-blind, long term extension trial, patients 12 years and older with severe asthma from trials NAVIGATOR and the additional trial [see Clinical Studies (14)] received TEZSPIRE 210 mg subcutaneously every 4 weeks or placebo for up to 104 weeks. In the trial, the incidence rates (IR) per 100 patient-years (PY) for serious cardiac adverse events in patients treated with TEZSPIRE or placebo were 1.08 and 0.21, respectively, with an incidence rate difference (IRD) of 0.88 (95% CI: 0.24, 1.53). The types of serious cardiac adverse events were heterogeneous. In the trial, the IR per 100 PY for adjudicated major adverse cardiovascular events (MACE, defined as cardiovascular deaths, non-fatal myocardial infarctions, and non-fatal strokes) in patients treated with TEZSPIRE or placebo were 0.60 and 0.42, respectively, with an IRD of 0.18 (95% CI: -0.51, 0.75).

5 Warnings and Precautions

5.1 Hypersensitivity Reactions

Additions and/or revisions underlined:

Hypersensitivity reactions were observed in the clinical trials (e.g., rash and allergic conjunctivitis) following the administration of TEZSPIRE. Postmarketing cases of anaphylaxis have also been reported [see Contraindications (4) and Adverse Reactions (6)]. These reactions can occur within hours of administration, but in some instances have a delayed onset (i.e., days). In the event of a hypersensitivity reaction, consider the benefits and risks for the individual patient to determine whether to continue or discontinue treatment with TEZSPIRE.

6 Adverse Reactions

Additions and/or revisions underlined:

The following clinically significant adverse reactions are described elsewhere in the labeling:

  • Hypersensitivity Reactions [see Warnings and Precautions (5.1)]

6.1 Clinical Trials Experience

Additions and/or revisions underlined:

Specific Adverse Reaction

Injection Site Reactions

In the pooled safety population (PATHWAY and NAVIGATOR), in which TEZSPIRE or placebo was administered using the vial by a healthcare provider, injection site reactions (e.g., injection site erythema, injection site swelling, injection site pain) occurred at a rate of 3.3% in patients treated with TEZSPIRE compared with 2.7% in patients treated with placebo.
In an open-label trial of 216 patients with asthma in which TEZSPIRE was administered by healthcare providers and patients or caregivers using either the pre-filled pen or pre-filled syringe, injection site reactions (e.g., injection site erythema, injection site swelling, injection site pain) were observed in 5.7% patients using the pre-filled pen and 0% using the pre-filled syringe. However, the trial was not designed to compare injection site reactions between patients who received TEZSPIRE by the pre-filled pen versus pre-filled syringe.

6.2 Postmarketing Experience

Subsection title revised

Newly added information

The following adverse reactions have been identified during post approval use of TEZSPIRE. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Hypersensitivity reactions: anaphylaxis

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

PATIENT COUNSELING INFORMATION

Additions and/or revisions underlined:

Advise the patient and/or caregiver to read the FDA-approved patient labeling (Patient Information and Instructions for Use).

Hypersensitivity Reactions
Inform patients that hypersensitivity reactions (e.g., anaphylaxis, rash and allergic conjunctivitis) can occur following administration of TEZSPIRE [see Contraindications (4) and Adverse Reactions (6)]. These reactions can occur within hours of administration, but in some instances have a delayed onset (i.e., days). Instruct patients to contact their healthcare provider if they experience symptoms of an allergic reaction [see Warnings and Precautions (5.1)].

Proper Storage and Disposal
Advise patients to refrigerate TEZSPIRE at 36°F to 46°F (2°C to 8°C). TEZSPIRE may be kept at room temperature between 68°F to 77?F (20°C to 25°C) for a maximum of 30 days [see How Supplied/Storage and Handling (16)]. Inform patients and caregivers of the need for proper disposal of the pre-filled pen after use, including the use of a sharps disposal container.
