2 DOSAGE AND ADMINISTRATION
INBRIJA capsules are for oral inhalation only and should be used only with the INBRIJA inhaler.
2.1 Important Administration Instructions
INBRIJA capsules are for oral inhalation only and should be used only with the INBRIJA inhaler. INBRIJA capsules must not be swallowed as the intended effect will not be obtained. INBRIJA capsules should be stored in their blister package and only removed immediately before use [see How Supplied/Storage and Handling (16.2)] .
2.2 Recommended Dosage
INBRIJA should be taken when symptoms of an OFF period start to return.
The recommended dosage of INBRIJA is oral inhalation of the contents of two 42 mg capsules (84 mg) as needed, up to 5 times a day. The maximum dose per OFF period is 84 mg, and the maximum daily dosage is 420 mg. INBRIJA has been shown to be effective only in combination with carbidopa/levodopa [see Indications and Usage (1)].
- 3 DOSAGE FORMS AND STRENGTHS
-
4 CONTRAINDICATIONS
INBRIJA is contraindicated in patients currently taking a nonselective monoamine oxidase (MAO) inhibitor (e.g., phenelzine and tranylcypromine) or who have recently (within 2 weeks) taken a nonselective MAO inhibitor. Hypertension can occur if these drugs are used concurrently [see Drug Interactions (7.1)].
-
5 WARNINGS AND PRECAUTIONS
5.1 Falling Asleep During Activities of Daily Living and Somnolence
Patients treated with levodopa, the active ingredient in INBRIJA, have reported falling asleep while engaged in activities of daily living, including the operation of motor vehicles, which sometimes resulted in accidents. Although many of these patients reported somnolence, some reported no warning signs (sleep attack) and believed that they were alert immediately prior to the event. Some of these events have been reported more than 1 year after the initiation of treatment.
Prescribers should reassess patients for drowsiness or sleepiness. Prescribers should also be aware that patients may not acknowledge drowsiness or sleepiness until directly questioned about drowsiness or sleepiness during specific activities.
Before initiating treatment with INBRIJA, advise patients about the potential to develop drowsiness and ask about factors that may increase the risk for somnolence with INBRIJA such as the concomitant use of sedating medications and the presence of sleep disorders. Consider discontinuing INBRIJA in patients who report significant daytime sleepiness or episodes of falling asleep during activities that require active participation (e.g., conversations, eating, etc.).
If treatment with INBRIJA continues, patients should be advised not to drive and to avoid other activities that might result in harm if the patients become somnolent. There is insufficient information to establish that dose reduction will eliminate episodes of falling asleep while engaged in activities of daily living.
5.2 Withdrawal-Emergent Hyperpyrexia and Confusion
A symptom complex that resembles neuroleptic malignant syndrome (characterized by elevated temperature, muscular rigidity, altered consciousness, and autonomic instability), with no other obvious etiology, has been reported in association with rapid dose reduction, withdrawal of, or changes in dopaminergic therapy.
5.3 Hallucinations/Psychosis
In placebo-controlled trials [see Clinical Studies (14)], hallucinations were reported in less than 2% of patients treated with INBRIJA. Hallucinations may be responsive to reducing levodopa therapy. Hallucinations may be accompanied by confusion, insomnia, and excessive dreaming. Abnormal thinking and behavior may present with one or more symptoms, including paranoid ideation, delusions, hallucinations, confusion, psychotic-like behavior, disorientation, aggressive behavior, agitation, and delirium.
Because of the risk of exacerbating psychosis, patients with a major psychotic disorder should ordinarily not be treated with INBRIJA. In addition, medications that antagonize the effects of dopamine used to treat psychosis may exacerbate the symptoms of Parkinson's disease and may decrease the effectiveness of INBRIJA [see Drug Interactions (7.2)].
5.4 Impulse Control/Compulsive Behaviors
Patients treated with INBRIJA can experience intense urges to gamble, increased sexual urges, intense urges to spend money, binge eating, and/or other intense urges, and the inability to control these urges while taking one or more of the medications that increase central dopaminergic tone. In some cases, although not all, these urges were reported to have stopped when the dose was reduced or the medication was discontinued.
Because patients may not recognize these behaviors as abnormal, it is important for prescribers to specifically ask patients or their caregivers about the development of new or increased gambling urges, sexual urges, uncontrolled spending or other urges while being treated with INBRIJA. Consider stopping the medication if a patient develops such urges while taking INBRIJA.
5.5 Dyskinesia
INBRIJA may cause or exacerbate dyskinesias. If troublesome dyskinesias occur, prescribers may need to consider stopping treatment with INBRIJA and/or adjusting the patient's daily medications for the treatment of Parkinson's disease. In Study 1, 4% of patients treated with INBRIJA 84 mg reported dyskinesia, compared with 1% for patients on placebo [see Adverse Reactions (6.1)] .
5.6 Bronchospasm in Patients with Lung Disease
Because of the risk of bronchospasm, use of INBRIJA in patients with asthma, COPD, or other chronic underlying lung disease is not recommended.
In a double-blind, placebo-controlled, crossover clinical study, 25 otherwise healthy subjects with mild or moderate asthma on a stable regimen of asthma medication received placebo or INBRIJA 84 mg every 4 hours for a total of three doses. Cough was the most frequent adverse reaction, reported by 60% of subjects following administration of INBRIJA and 0% following administration of placebo. Following administration of INBRIJA, 10 subjects (40%) had temporary reductions from baseline (between 15% and 59%) for FEV 1; 4 of these subjects also had a reduction in FEV 1 following administration of placebo. Subjects with a reduction in FEV 1 remained asymptomatic and did not require rescue treatment.
5.7 Glaucoma
INBRIJA may cause increased intraocular pressure in patients with glaucoma. Monitor patients for increased intraocular pressure during therapy with INBRIJA.
5.8 Laboratory Test Abnormalities
Abnormalities in laboratory tests may include elevations of liver function tests such as alkaline phosphatase, AST, ALT, lactic dehydrogenase (LDH), and bilirubin. Abnormalities in blood urea nitrogen (BUN), hemolytic anemia and positive direct antibody test have also been reported.
Patients taking levodopa or carbidopa-levodopa may have increased levels of catecholamines and their metabolites in plasma and urine giving false positive results suggesting the diagnosis of pheochromocytoma in patients on levodopa and carbidopa-levodopa.

6.1 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 clinical practice.
Adverse Reactions in Study 1
Table 1 lists the adverse reactions that occurred in at least 2% of patients with Parkinson's disease who were treated with INBRIJA 84 mg and higher than placebo for OFF periods in Study 1 [see Clinical Studies (14)]. Study 1 was a double-blind, placebo-controlled study, in which 114 patients received INBRIJA 84 mg (two 42 mg capsules) for an average of 2 doses per day, to a maximum of 5 times a day, and 112 patients received placebo. INBRIJA-treated patients were 45-82 years of age (mean 63.5 years of age) and were predominantly male (72%) and white (94%). All patients were also treated with oral carbidopa/levodopa. The most common adverse reactions (≥ 5% and higher than placebo) in Study 1 were cough, nausea, upper respiratory tract infection, and sputum discolored.

In Study 1, 6 of 114 patients (5%) in the INBRIJA 84 mg group and 3 of 112 patients (3%) in the placebo group discontinued because of adverse reactions. The most common of these adverse reactions was cough, which lead to discontinuation in 2% of patients in the INBRIJA 84 mg group and none in the placebo group.
6.2 Postmarketing Experience
The following adverse reaction has been identified during post approval use of INBRIJA. Because adverse 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: sensation of choking immediately following administration.
-
7 DRUG INTERACTIONS
7.1 Monoamine Oxidase (MAO) Inhibitors
The use of nonselective MAO inhibitors with INBRIJA is contraindicated [see Contraindications (4)] . Discontinue use of any nonselective MAO inhibitors at least two weeks prior to initiating INBRIJA.
The use of selective MAO-B inhibitors with INBRIJA may be associated with orthostatic hypotension. Monitor patients who are taking these drugs concurrently.
-
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
There are no adequate data on the developmental risk associated with the use of INBRIJA in pregnant women. In animal studies, carbidopa/levodopa has been shown to be developmentally toxic (including teratogenic effects) [see Data]. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The background risk of major birth defects and miscarriage for the indicated population is unknown.
Data
Animal Data
When administered to pregnant rabbits throughout organogenesis, carbidopa/levodopa caused both visceral and skeletal malformations in rabbits. No teratogenic effects were observed when carbidopa/levodopa was administered to pregnant mice throughout organogenesis.
There was a decrease in the number of live pups delivered by rats receiving carbidopa/levodopa during organogenesis.
8.2 Lactation
Risk Summary
The prolactin-lowering action of dopamine suggests that levodopa may interfere with lactation, although there are limited data on the effects of levodopa on milk production in lactating women.
Levodopa has been detected in human milk. There are no adequate data on the effects of levodopa on the breastfed infant. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for INBRIJA and any potential adverse effects on the breastfed infant from INBRIJA or from the underlying maternal condition.
8.5 Geriatric Use
Of the Parkinson's disease patients in Study 1 who took INBRIJA 84 mg, 49% (n=56) were 65 years of age and older and 51% (n=58) were under 65 years of age. Of these patients, the following age-related differences in adverse reactions were reported in patients 65 years of age and older vs. in patients under 65 years of age, respectively: cough 25% vs. 5%; upper respiratory tract infection 11% vs. 2%; nausea 7% vs. 3%; vomiting 4% vs. 2%; pain in the extremities 4% vs. 0%; and discolored nasal discharge 4% vs. 0%.
-
10 OVERDOSAGE
Based on the limited available information, the acute symptoms of carbidopa/levodopa overdosage can be expected to arise from dopaminergic overstimulation. Using more than one dose (84 mg) to treat the same OFF period may result in CNS disturbances, with an increasing risk for cardiovascular disturbance (e.g., hypotension, tachycardia) and increased risk for new or worsening psychiatric problems at higher doses.
Reports of rhabdomyolysis and transient renal insufficiency suggest that levodopa overdosage may give rise to systemic complications.
Monitor patients and provide supportive care. Patients should receive electrocardiographic monitoring for the development of arrhythmias; if needed, appropriate antiarrhythmic therapy should be given. The possibility that the patient may have taken other drugs, increasing the risk of drug interactions (especially catechol-structured drugs) should be taken into consideration.
-
11 DESCRIPTION
INBRIJA consists of a dry powder formulation of levodopa for oral inhalation with the INBRIJA inhaler. The inhalation powder is packaged in white hypromellose capsules.
Each capsule contains a spray-dried powder of 42 mg levodopa active ingredient with 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and sodium chloride.
The active component of INBRIJA is levodopa, an aromatic amino acid. Its chemical name is (2S)-2-amino-3-(3,4-dihydroxyphenyl) propanoic acid and its structural formula is:
Levodopa has a molecular weight of 197.19 g/mol and molecular formula C 9H 11NO 4. Levodopa is a white to slightly off-white powder and is readily soluble in formic acid, slightly soluble in water, and practically insoluble in ethanol and diethyl ether; it dissolves in dilute hydrochloric acid.
The INBRIJA inhaler is a plastic device with a blue body, blue cap, and white mouthpiece used for inhaling INBRIJA powder.
The INBRIJA inhaler is breath-actuated by the patient. Under standardized in vitro testing conditions, the INBRIJA inhaler delivered 36.1 mg of levodopa (emitted dose) for the 42 mg capsule from the mouthpiece. No significant difference in emitted dose was observed when varying the flow rate and volume from 20 liters per minute/1L up to 90 liters per minute/2L. Peak inspiratory flow rates (PIFR) achievable through the INBRIJA inhaler were evaluated in 24 adult patients with mild to moderate Parkinson's disease. The mean PIFR was 64 L/min (range 39–98 L/min) for patients in the ON state and 57 L/min (range 29–98 L/min) in the OFF state.
-
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Levodopa, the metabolic precursor of dopamine, crosses the blood-brain barrier and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa relieves symptoms of Parkinson's disease.
12.3 Pharmacokinetics
In the presence of carbidopa, the pharmacokinetics of levodopa are dose-proportional in healthy subjects taking up to 84 mg of INBRIJA. In the presence of carbidopa, the terminal elimination half-life (t 1/2) of levodopa following a single administration of INBRIJA 84 mg was 2.3 hours.
Absorption
After a single dose of INBRIJA 84 mg (two 42 mg capsules), the median T max for plasma levodopa was approximately 0.5 hours (range 0.17–2.00 hours). In fasted healthy volunteers the bioavailability of levodopa from INBRIJA was approximately 70% relative to immediate-release oral levodopa tablets. The dose-normalized C max of levodopa from INBRIJA is approximately 50% of that following immediate-release oral tablets.
Metabolism and Elimination
Levodopa is extensively metabolized, and the two major metabolic pathways are decarboxylation by dopa decarboxylase and O-methylation by catechol-O-methyltransferase (COMT).
Specific Populations
Geriatric Population
Clinical studies specifically designed to analyze the effects of age on the pharmacokinetics of levodopa were not conducted with INBRIJA.
Male and Female Patients
After a single dose administration of INBRIJA 84 mg, the body-weight adjusted C max and AUC 0-24 were similar between women and men. No adjustment in dosage is required based on sex.

-
14 CLINICAL STUDIES
The efficacy and safety of INBRIJA for the treatment of OFF episodes in patients with Parkinson's disease treated with oral carbidopa/levodopa was evaluated in a 12-week, randomized, placebo-controlled, double-blind study (Study 1; NCT02240030).
Study 1:
In Study 1, a total of 114 patients were treated with INBRIJA 84 mg (two 42 mg capsules), and 112 patients received placebo. Study medication could be administered up to five times a day. At baseline, patients had at least 2 hours of OFF time per day, and carbidopa/levodopa medication did not exceed 1600 mg levodopa per day. The mean UPDRS Part III scores at screening in the ON state were 14.9 for patients randomized to INBRIJA 84 mg and 16.1 for patients randomized to placebo. The UPDRS part III is designed to assess the severity of the cardinal motor findings (e.g., tremor, rigidity, bradykinesia, postural instability) in patients with Parkinson's disease.
The primary endpoint was the change in Unified Parkinson's Disease Rating Scale (UPDRS) Part III motor score from pre-dose OFF state to 30 minutes post-dose, measured at Week 12. The average use of INBRIJA 84 mg or placebo was approximately 2 doses per day. At Week 12, the reduction in UPDRS Part III motor score for INBRIJA 84 mg, compared to placebo at 30 minutes post-dose, were -9.8 and -5.9, respectively (See Table 2 and Figure 1). The proportion of patients who returned to an ON state and sustained that ON through 60 minutes post-dose was 58% for INBRIJA 84 mg and 36% for placebo (p=0.003).

Study 2
The effect of INBRIJA on pulmonary function was evaluated in patients with Parkinson's disease treated with oral carbidopa/levodopa in a 12 month, randomized, controlled, open-labeled study (Study 2: NCT02352363). A total of 271 patients were treated with INBRIJA 84 mg (two 42 mg capsules), and 127 patients with Parkinson's disease in a control group were observed on their regular oral medication regimen for the treatment of Parkinson's disease. Patients with chronic obstructive pulmonary disease (COPD), asthma, or other chronic respiratory disease within the last 5 years were excluded [see Warnings and Precautions (5.6)]. Pulmonary function was assessed by spirometry every 3 months in both groups. After 12 months, the average reduction in the forced expiratory volume in 1 second (FEV 1) from baseline was the same in both groups (-0.1 L).

17 PATIENT COUNSELING INFORMATION
Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use).
Instructions for Administering INBRIJA
It is important for patients to understand how to correctly administer INBRIJA. It is recommended that patients be instructed in the proper administration of INBRIJA prior to use [see Dosage and Administration (2.1)] .
Patients should be counseled to take a dose of INBRIJA when the return of their Parkinson's symptoms (OFF periods) first occur [see Dosage and Administration (2.2)] .
Instruct patients to read the Instructions for Use before using INBRIJA. Remind patients that INBRIJA capsules should only be administered via the INBRIJA inhaler and the INBRIJA inhaler should not be used for administering other medications. Remind patients that the contents of INBRIJA capsules are for oral inhalation only and must not be swallowed. Instruct patients to keep INBRIJA capsules in their sealed blister packaging and to remove each INBRIJA capsule immediately before using [see Dosage and Administration (2.1)] .
Remind patients they need to orally inhale the contents of two capsules to take a full dose. They should not take more than 5 doses of INBRIJA in one day. Instruct patients they should not take more than one dose (2 capsules) per OFF period [see Dosage and Administration (2.2)] .
Lung Disease
Ask patients to report whether they develop asthma, COPD, or other chronic lung diseases, since INBRIJA is not recommended in patients with these conditions [see Warnings and Precautions (5.6)] .
Cough/Sensation of Choking
Inhalation of INBRIJA can lead to coughing or a sensation of choking at the time of administration [see Warnings and Precautions (5.6), and Adverse Reactions (6.1, 6.2)] .
Discoloration of Body Fluids
Patients should be advised that dark color may appear in bodily fluids (saliva, sputum, urine, or sweat) when using INBRIJA [see Adverse Reactions (6.1)] .
Falling Asleep
Advise patients that certain side effects such as sleepiness and dizziness may affect some patients' ability to drive and operate machinery safely. Advise patients of the possible additive sedative effects when taking other CNS depressants in combination with INBRIJA [see Warnings and Precautions (5.1)] .
Impulse Control Disorder
Inform patients of the potential for experiencing Impulse Control Disorder: patients may experience intense urges to gamble, increased sexual urges, and other intense urges and the inability to control these urges while taking one or more of the medications that increase central dopaminergic tone, that are generally used for the treatment of Parkinson's disease [see Warnings and Precautions (5.4)] .
Dyskinesia
Instruct patients to notify their healthcare provider if abnormal involuntary movements appear or get worse during treatment with INBRIJA [see Warnings and Precautions (5.5)] .
Hypotension and Syncope
Advise patients that while they are on levodopa therapy, including INBRIJA, that they may develop orthostatic hypotension with or without symptoms such as dizziness, nausea, syncope, and sweating [see Adverse Reactions (6.1)] . Advise patients to rise slowly after sitting or lying down, especially if they have been doing so for a prolonged period.
Iron Salts
Inform patients that iron salts or multivitamins containing iron salts can reduce the bioavailability of levodopa [see Drug Interactions (7.3)].
Pregnancy and Breastfeeding
Instruct patients to notify their physicians if they become pregnant or intend to become pregnant during therapy [see Use in Specific Populations (8.1)] .

- You could fall asleep without being drowsy or without warning. If you become drowsy while using INBRIJA, you should not drive or do activities where you need to be alert for your safety or the safety of others.
- Your chances of falling asleep while doing normal activities while using INBRIJA are greater if you take other medicines that cause drowsiness. Tell your healthcare provider if you take medicines that can make you sleepy such as sleep medicines, antidepressants, or antipsychotics.

If you or your family members notice that you are having unusual urges, talk to your healthcare provider.
- uncontrolled, sudden body movements (dyskinesia). INBRIJA may cause or worsen movements you cannot control in your face, tongue, or other body parts. Tell your healthcare provider if this happens. Your treatment with INBRIJA may need to be stopped or your other medicines for Parkinson's may need to be changed.
- bronchospasm. People with lung disease such as asthma, COPD, or other lung diseases have a risk of wheezing or difficulty breathing (bronchospasm) after inhaling INBRIJA. If you have these symptoms, stop taking INBRIJA and call your healthcare provider or go to the nearest hospital emergency room right away.

Parts of your INBRIJA Inhaler
(see Figure A)
Capsules (see Figure B)
Each carton includes strips of 4 capsules.
(see Figure C)
Prepare and take a total of 2 capsules.
Take each capsule 1 at a time for a full dose.
(see Figure D)
Full Dose = 2 Capsules
Prepare Your Dose
Step 1. Gather Supplies
Find a clean and dry surface.
Make sure your hands are clean and dry.
Get inhaler and strip of capsules.
Tear off package of 2 capsules (see Figure E).
Step 2. Check Expiration
Check the expiration date on the package (see Figure F).
Step 3. Remove Blue Cap
Pull the cap straight off (see Figure G).
Place the cap to the side. You will need it later to store the inhaler.
Step 4. Twist Off White Mouthpiece
Twist and pull off the mouthpiece to separate it from the handle (see Figure H).
Place the mouthpiece and inhaler on a clean and dry surface.
Step 5. Remove 1 Capsule From Package
Carefully peel back the foil and take out 1 capsule (see Figure I).
Do not try to push the capsule through the back of the foil package.
Only remove 1 capsule at a time, and just before use.
Do not use any capsule that looks crushed, damaged or wet. Throw it away and get a new capsule.
Step 6. Load Capsule
Hold the inhaler upright using the handle.
Drop 1 capsule into the opening of the capsule chamber (see Figure J).
Do not try to load 2 capsules at the same time.
Step 7. Attach White Mouthpiece
Line up the white arrows on the handle and mouthpiece (see Figure K).
Firmly push the mouthpiece and handle together until you hear a click. This punctures the capsule (see Figure L). 
Release the mouthpiece. The mouthpiece will spring back and stay attached (see Figure M).
Your inhaler is now ready to use.
Do not push the handle and mouthpiece together more than 1 time. This may damage the capsule, and you may not get your full dose. If this happens throw the capsule away in your household trash and start over at Step 5.
Make sure the mouthpiece is securely attached and will not fall off before moving to step 8.
Take Your Dose Step 8. Breathe Out (Exhale)
Stand or sit with your head and chest upright.
Hold the inhaler level and away from your mouth (see Figure N).
Breathe out completely (see Figure N).
Do not breathe into mouthpiece.
Step 9. Breathe In Deeply (Inhale)
While keeping the inhaler level, close your lips firmly around the mouthpiece (see Figure O).
Take in a deep, comfortable breath until your lungs feel full. This normally takes several seconds.
As you breathe in, you will hear and feel the capsule "whirl" (spin). The whirl means the inhaler is working and you are getting your medicine.
If you cough or stop your dose, start again from the beginning of Step 8 using the same capsule.
Important: If you did not hear or feel the capsule "whirl" while inhaling you may need to take a deeper, longer breath or may need to clean the mouthpiece. Refer to Step 14 – Clean Mouthpiece. Start again from the beginning of Step 8 using the same capsule. Step 10. Hold Breath, Then Breathe Out
Take the inhaler out of your mouth and hold your breath for 5 seconds (see Figure P).
Then breathe out.
Step 11. Remove Capsule From Inhaler
Twist and pull off the mouthpiece (see Figure Q) and take out the used capsule (see Figure R).
Step 12. Dose With 2 nd Capsule
Repeat Steps 5 to 11 with the second capsule to finish the full dose (see Figure S).
Dispose and Store Step 13. Throw Out Used Capsules Throw out used capsules in the household trash (see Figure T). 
Step 14. Clean Mouthpiece
It is normal for some powder to remain in or on the inhaler. To avoid powder buildup, clean the powder off of the mouthpiece holes using a circular motion with a new dry cotton swab as needed.
First, clean the holes from the top end of the mouthpiece (see Figure U).
Next, clean the holes from the bottom end of the mouthpiece (see Figure V).
You can also use a dry tissue to wipe the outside of the mouthpiece, as needed.
Do not clean any other parts of the inhaler.
Do not rinse the mouthpiece or get the inhaler wet.
Step 15. Store Inhaler
Make sure there are no capsules in the inhaler before you store it.
Attach the mouthpiece to the handle by pushing until you hear a click (see Figure W).
Attach the cap over the mouthpiece (see Figure X).
Your inhaler is now ready to store (see Figure Y).INBRIJA Storage, Cleaning and Disposal
