Instructions for Use

TYRVAYA™
(Teer-vye-ah) (varenicline solution) nasal spray, for intranasal use

Read this Instructions for Use before you start using TYRVAYA and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

Important information you need to know before using TYRVAYA:

• TYRVAYA is for use in the nose.
• Do not shake the bottles.

Parts of your TYRVAYA nasal spray:

 

 

 

• The TYRVAYA carton contains enough medicine for 30 days.
  • Each carton has 2 glass nasal spray bottles.
  • Each nasal spray bottle has enough medicine for 15 days of treatment.
  • Do not open the second nasal spray bottle until you have used the entire first bottle.

Steps for priming TYRVAYA before first Use

Step 1. Remove the cap and the clip.

Do not throw away the cap or the clip. The cap and the clip will be placed back on to the nasal applicator after each use.

 

 

 

Step 2. Hold the nasal spray bottle upright and away from your face. Place 1 finger on each side of the base of the nasal applicator and place your thumb underneath the bottle.

 

 

 

Step 3. Prime the nasal spray bottle by pressing and releasing the nasal applicator 7 times with your thumb and fingers. You may not see a spray released each time you press and release the nasal applicator. Spray away from yourself and others.

TYRVAYA is now primed for use.

 

 

 

• Reprime: If you do not use TYRVAYA for more than 5 days, you will need to reprime the nasal spray bottle with 1 spray before you start using it. To reprime, hold the nasal spray bottle upright and away from your face and press and release the nasal spray applicator 1 time.
• Avoid priming the nasal spray bottle more than needed: Priming the nasal spray bottle more than needed will reduce the amount of medicine in the nasal spray bottle.

Steps for using TYRVAYA nasal spray after priming

Step 1. Blow your nose to clear your nostrils, if needed.

 

 

 

Step 2. Remove the cap and clip.

Do not throw away the cap or the clip. The cap and the clip will be placed back on to the nasal applicator after each use.

 

 

 

Step 3. Hold the nasal spray bottle upright. Place 1 finger on each side of the base of the nasal applicator and your thumb underneath the bottle.

 

 

 

Step 4. Tilt your head back slightly without lying down.

 

 

 

Step 5. Insert the nasal applicator into the left or right nostril. Tilt the nasal applicator and point the tip of the nasal applicator towards the top of the ear on the same side as your nostril.

Do not press the tip of the nasal applicator against the wall of the inside of your nose. Leave a space between the tip of the nasal applicator and the wall of the inside of your nose.

 

 

 

Step 6. Place your tongue to the roof of your mouth and breathe gently while pressing and releasing the nasal applicator 1-time to release a spray into your nostril.

Repeat Steps 5 and 6 to deliver a second spray in the other nostril.

 

 

 

Step 7. Wipe the nasal applicator with a clean tissue.

 

 

 

Step 8. Replace the clip and the cap. Repeat Steps 1 to 8 each time you use TYRVAYA.

Description

TYRVAYA nasal spray contains varenicline which is a partial nicotinic acetylcholine receptor agonist of α4β2, α4α6β2, α3β4, and α3α5β4 receptors and a full α7 receptor agonist.

Varenicline, as the tartrate salt, is a powder which is a white to off-white to slightly yellow solid whose chemical name is 7,8,9,10-tetrahydro-6,10-methano-6H-pyrazino[2,3-h][3]benzazepine, (2R,3R)-2,3-dihydroxybutanedioate (1:1). It is highly soluble in water. Varenicline tartrate has a molecular weight of 361.35 Daltons and a molecular formula of C₁₃H₁₃N₃ • C₄H₆O₆. The chemical structure is:

TYRVAYA (varenicline solution) nasal spray is formulated for intranasal use as a clear 0.6 mg/mL strength solution, at pH 6.4.

Side Effects

Clinical Trials Experience

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.

In three clinical studies of dry eye disease conducted with varenicline solution nasal spray, 349 patients received at least 1 dose of TYRVAYA. The majority of patients had 31 days of treatment exposure, with a maximum exposure of 105 days.

The most common adverse reactions reported in 82% of TYRVAYA treated patients was sneezing. Other common adverse reactions that were reported in >5% of patients include cough (16%), throat irritation (13%), and instillation-site (nose) irritation (8%).

• Instruct patients to not shake or freeze the bottle.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Carcinogenesis

Lifetime carcinogenicity studies were performed in CD-1 mice and Sprague-Dawley rats. There was no evidence of a carcinogenic effect in mice administered varenicline by oral gavage for 2 years at doses up to 20 mg/kg/day (810 times the maximum recommended human dose [MRHD], on a mg/m² basis). Rats were administered varenicline (1, 5, and 15 mg/kg/day) by oral gavage for 2 years. In male rats (n = 65 per sex per dose group), incidences of hibernoma (tumor of the brown fat) were increased at the mid dose (1 tumor, 5 mg/kg/day, 405 times the MRHD on a mg/m² basis) and maximum dose (2 tumors, 15 mg/kg/day, 1216 times the MRHD on a mg/m² basis). The clinical relevance of this finding to humans has not been established. There was no evidence of carcinogenicity in female rats.

Mutagenesis

Varenicline was not genotoxic, with or without metabolic activation, in the following assays: Ames bacterial mutation assay; mammalian CHO/HGPRT assay; and tests for cytogenetic aberrations in vivo in rat bone marrow and in vitro in human lymphocytes.

Impairment Of Fertility

There was no evidence of impairment of fertility in either male or female Sprague-Dawley rats administered varenicline succinate up to 15 mg/kg/day (1216 times the MRHD on a mg/m² basis). Maternal toxicity, characterized by a decrease in body weight gain, was observed at 15 mg/kg/day. A decrease in fertility was noted in the offspring of pregnant rats administered varenicline succinate at an oral dose of 15 mg/kg/day. The decrease in fertility in the offspring of treated female rats was not evident at an oral dose of 3 mg/kg/day (243 times the MRHD, on a mg/m² basis).

Use In Specific Populations

Pregnancy

Risk Summary

There are no available data on TYRVAYA use in pregnant women to inform any drug associated risks. In animal reproduction studies, varenicline did not produce malformations at clinically relevant doses.

All pregnancies have a risk of birth defect, loss, or other adverse outcomes. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

Pregnant rats and rabbits received varenicline succinate during organogenesis at oral doses up to 15 and 30 mg/kg/day, respectively. While no fetal structural abnormalities occurred in either species, maternal toxicity, characterized by reduced body weight gain, and reduced fetal weights occurred in rabbits at the highest dose (4864 times the MRHD on a mg/m² basis).

In a pre- and postnatal development study, pregnant rats received up to 15 mg/kg/day of oral varenicline succinate from organogenesis through lactation. Maternal toxicity, characterized by a decrease in body weight gain, was observed at 15 mg/kg/day (1216 times the MRHD on a mg/m² basis). Decreased fertility and increased auditory startle response occurred in offspring at the highest maternal dose of 15 mg/kg/day.

Lactation

Risk Summary

There are no data on the presence of varenicline in human milk, the effects on the breastfed infant, or the effects on milk production. In animal studies varenicline was present in milk of lactating rats. However, due to species-specific differences in lactation physiology, animal data may not reliably predict drug levels in human milk.

The lack of clinical data during lactation precludes a clear determination of the risk of TYRVAYA to an infant during lactation; however, the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TYRVAYA and any potential adverse effects on the breastfed child from TYRVAYA.

Pediatric Use

Safety and efficacy of TYRVAYA in pediatric patients have not been established.

Geriatric Use

No overall differences in safety or effectiveness have been observed between elderly and younger adult patients.

Overdose

Contraindications

None

Clinical Pharmacology

Mechanism Of Action

The efficacy of TYRVAYA in dry eye disease is believed to be the result of varenicline’s activity at heteromeric sub-type(s) of the nicotinic acetylcholine (nACh) receptor where its binding produces agonist activity and activates the trigeminal parasympathetic pathway resulting in increased production of basal tear film as a treatment for dry eye disease. Varenicline binds with high affinity and selectivity at human α4β2, α4α6β2, α3β4, α3α5β4 and α7 neuronal nicotinic acetylcholine receptors. The exact mechanism of action is unknown at this time.

Pharmacokinetics

Absorption/Distribution

Following administration of 0.12 mg (0.06 mg per 50-μL spray in each nostril), a strength of varenicline that is higher than the labeled concentration, varenicline can be detected in plasma by 5 minutes, generally achieves peak concentration within 2 hours, with a mean Cmax of 0.34 ng/mL, and has an AUC0-inf of 7.46 h*ng/mL. The systemic exposure (AUC0-inf) following this intranasal dose was approximately 7.5% of the exposure observed following a 1 mg oral dose of varenicline.

Metabolism/Elimination

The mean ± SD elimination half-life of varenicline after intranasal administration is approximately 19 ± 10 hours. Varenicline undergoes minimal metabolism with 92% excreted as unchanged drug in the urine.

Clinical Studies

The efficacy of TYRVAYA for the treatment of dry eye disease was supported by two randomized, multi-center, double-masked, vehicle-controlled studies (ONSET-1 and ONSET-2). In the ONSET-1 study, 182 patients were randomized in a 1:1:1:1 ratio to receive one spray in each nostril twice daily of varenicline solution 0.006 mg (N=47), TYRVAYA 0.03 mg (N=48), varenicline solution 0.06 mg (N=44), or vehicle (N=43). In the ONSET-2 study, 758 patients were randomized in a 1:1:1 ratio to receive one spray in each nostril twice daily of TYRVAYA 0.03 mg (N=260), varenicline solution 0.06 mg (N=246), or vehicle (N=252).

The majority of patients were female (74%), the mean (standard deviation [SD]) age was 61 (12.5) years, the mean (SD) baseline anesthetized Schirmer’s score was 5.1 mm (2.9), and the mean (SD) baseline eye dryness score (EDS) was 59.3 (21.6. Use of artificial tears was allowed during the studies. Enrollment criteria included minimal signs [i.e., anesthetized Schirmer’s test score (range, 0-10 mm) and corneal fluorescein staining (range, 2-14)] and was not limited by baseline EDS (range, 2-100).

Efficacy

Tear film production was measured by anesthetized Schirmer’s score assessed using a Schirmer’s strip (0-35 mm). The average baseline Schirmer’s score was 5.0 mm in the ONSET-1 study and 5.1 mm in the ONSET-2 study. Of the patients treated with TYRVAYA, 52% achieved ≥10 mm increase in Schirmer’s score from baseline in the ONSET-1 study and 47% achieved ≥10 mm increase in Schirmer’s score from baseline in the ONSET-2 study, compared to 14% and 28% of vehicle-treated patients in the ONSET-1 study and the ONSET-2 study, respectively at Day 28 (see Table 1). Of the patients treated with TYRVAYA, the mean change in Schirmer’s score was 11.7 mm and 11.3 mm as compared to 3.2 mm and 6.3 mm in the vehicle treated patients in the ONSET-1 study and ONSET-2 study, respectively at Day 28.
