11 Description

Dornase alfa is a recombinant human deoxyribonuclease I (rhDNase) an enzyme which selectively cleaves DNA. The protein is produced by genetically engineered Chinese Hamster Ovary (CHO) cells containing DNA encoding for the native human protein, deoxyribonuclease I (DNase). The product is purified by column chromatography and tangential flow filtration. The purified glycoprotein contains 260 amino acids with an approximate molecular weight of 37,000 daltons. The primary amino acid sequence is identical to that of the native human enzyme.

PULMOZYME (dornase alfa) inhalation solution is administered by inhalation of an aerosol mist produced by a compressed air driven nebulizer or a recommended nebulizer system [see Clinical Studies (14) and Dosage and Administration (2.2)]. PULMOZYME is a sterile, clear, colorless, highly purified solution in single-dose ampules. Each ampule delivers 2.5 mL of the solution to the nebulizer bowl. Each mL of aqueous solution contains 1 mg dornase alfa, calcium chloride dihydrate (0.15 mg) and sodium chloride (8.77 mg). The solution contains no preservative. The nominal pH of the solution is 6.3.

8.4 Pediatric Use

The safety and effectiveness of PULMOZYME in conjunction with standard therapies for cystic fibrosis have been established in pediatric patients. Use of PULMOZYME in pediatric patients is supported by evidence in the following age groups:

  • Patients 5 to 17 years of age: Use of PULMOZYME in patients 5 to 17 years of age is supported by evidence from a randomized, placebo-controlled trial of 303 of clinically stable cystic fibrosis patients 5 to 17 years of age who received PULMOZYME [see Clinical Studies (14)].
  • Patients less than 5 years: Use of PULMOZYME in patients less than 5 years of age is supported by extrapolation of efficacy data in patients 5 years of age and older with additional safety data in 65 pediatric patients aged 3 months to less than 5 years who received PULMOZYME 2.5 mg daily by inhalation for 2 weeks [see Adverse Reactions (6.1) and Clinical Studies (14)].
8.5 Geriatric Use

Cystic fibrosis is primarily a disease of children and young adults. Clinical studies of PULMOZYME did not include sufficient numbers of subjects aged 65 or older to determine whether they respond differently from younger subjects.

4 Contraindications

PULMOZYME is contraindicated in patients with known hypersensitivity to dornase alfa, Chinese Hamster Ovary cell products, or any component of the product.

6 Adverse Reactions

The most common adverse reactions (occurring in ≥3% of patients treated with PULMOZYME over placebo) seen in clinical trials in CF patients were: voice alteration, pharyngitis, rash, laryngitis, chest pain, conjunctivitis, rhinitis, decrease in FVC of ≥10%, fever, and dyspnea. (6.1)

Instructions for Use

PULMOZYME® (PULL-muh-zyme)

(dornase alfa)

Inhalation Solution

This Instructions for Use contains information on how to use PULMOZYME with Jet Nebulizers and Compressors

See the other side of this Instructions for Use for information on use of Pulmozyme with the recommended vibrating mesh nebulizers

Read and understand this Instructions for Use and the nebulizer manufacturer's instruction manual before you start taking Pulmozyme and each time you get a refill. There may be new information. This information does not take the place of talking to your doctor about your medical condition or your treatment.

A nebulizer and a compressor are used together to give a dose of Pulmozyme. A nebulizer changes the Pulmozyme liquid medicine into a fine mist you inhale by breathing through a mouthpiece. A compressor gives the nebulizer power and makes the nebulizer work.

Pulmozyme should only be used with the approved nebulizers and appropriate compressors as recommended below, or with the recommended vibrating mesh nebulizers (see other side of this Instructions for Use). Read and follow the manufacturer's instruction manual.

Do not use any other inhaled medicines in the nebulizer at the same time. Keep all other inhaled medicine systems completely separate from Pulmozyme.

Use the mouthpiece or face mask provided with the nebulizer kit.

If your child cannot breathe in or breathe out by mouth, you may use the PARI BABY reusable nebulizer, but you should discuss it with your doctor first. The PARI BABY nebulizer is the same as the PARI LC Plus Jet system, except the mouthpiece is replaced by a tight-fitting face mask connected to an elbow piece.

Follow the steps on this side of the Instructions for Use to give Pulmozyme using the following jet nebulizer systems

Jet Nebulizer Compressor
Hudson T Up-draft II A compressor with the following specifications is recommended:
  • Approximate air flow of 3.5 L/min to 12 L/min at approximately 20 psi to 45 psi pressure
Marquest Acorn II
PARI LC Plus
PARI BABY
Durable Sidestream

For additional information on an appropriate compressor to use with Pulmozyme, read the manufacturer's instruction manual for the recommended nebulizer.

  • Plastic T (not needed for Sidestream nebulizer or PARI BABY)
  • Flexible aerosol tube (not needed for Sidestream nebulizer or PARI BABY)
  • Mouthpiece (clean) or PARI BABY facemask
  • Long connecting tube
  • Nose clip (optional, not needed for PARI BABY)
Preparing the jet nebulizer and compressor:

Step 1. Clean a flat table surface and wash your hands.
  • Clean a flat table surface.
  • Wash your hands well with soap and water before using the Pulmozyme ampule and nebulizer. This helps prevent infection (See Figure B).
Step 2. Gather the nebulizer and test the compressor.
  • Place the nebulizer parts on a clean, flat table surface within reach.
  • Test the compressor by turning it on and putting your finger in front of the "air out" or "air" port to feel air flowing. Turn off the compressor (See Figure C).
Step 3. Gather the Pulmozyme ampule and check the expiration date.
  • Remove 1 foil pouch of Pulmozyme from the refrigerator. Open the foil pouch and remove 1 ampule of Pulmozyme. Put the remaining ampules back in the foil pouch and return them to the refrigerator.
  • Check the expiration (exp.) date printed on the ampule (See Figure D).
  • Do not use the Pulmozyme ampule if the expiration date has passed.
Step 4. Check the Pulmozyme ampule.
  • Check the ampule for leaks by turning it upside down and gently squeezing (See Figure E).

    Do not use the ampule if it is leaking. Throw it away and get a new one.
  • Check the Pulmozyme liquid in the ampule and make sure it is clear and free of particles.
  • Do not use Pulmozyme if the liquid is cloudy or discolored. Take the Pulmozyme back to the pharmacy, hospital, or clinic that gave you the medicine.
Step 5. Attach the long connecting tube to the compressor.
  • Attach the long connecting tube to the "air out" or "air" port on the compressor (See Figure F).
Step 6. Attach the mouthpiece.
  • Skip to Step 7 if you use the Sidestream nebulizer or the PARI BABY nebulizer.
  • Push the mouthpiece into the wider end of the plastic T. Attach the flexible aerosol tube to the other end of the T (See Figure G).
Step 7. Remove the cap from the cup.
  • Unscrew or unsnap the cap from the nebulizer cup (See Figure H).
  • Put the nebulizer cup on the table face up and place the cap upside down on a clean surface (See Figure I).
Step 8. Open the Pulmozyme ampule.
  • Hold the tab at the bottom of the Pulmozyme ampule firmly. Twist off the top. Do not squeeze the body of the ampule (See Figure J).
Step 9. Pour the full Pulmozyme dose into the nebulizer cup.
  • Turn the ampule upside down and squeeze gently to empty the medicine into the nebulizer cup. Keep squeezing until the ampule is empty. It is very important you squeeze all of the medicine out of the ampule (See Figure K).
  • Screw or snap the cap onto the nebulizer cup (See Figure L).
Step 10. Connect the plastic T.
  • Connect the plastic T to the nebulizer cap (See Figure M).
  • If you are using the Sidestream nebulizer, attach the mouthpiece to the top of the nebulizer (See Figure N).
  • If you are using the PARI BABY nebulizer, connect the elbow piece and mask to the nebulizer outlet (See Figure O).
Step 11. Attach the long connecting tube to the cup.
  • Connect the open end of the long connecting tube to the port on the bottom of the nebulizer cup by pushing up firmly (See Figure P).
Step 12. Turn on the compressor.
  • Turn on the compressor and check to see that mist is coming out of the nebulizer (See Figure Q).
Taking your dose of Pulmozyme with a nebulizer:
Step 13. Breathe through the mouthpiece.
  • Skip to Step 14 if you are using the PARI BABY to give Pulmozyme to your child.
  • Place the mouthpiece between your teeth and on top of your tongue (See Figure R).
  • Breathe slowly in and out through your mouth. Do not block the airflow with your tongue.
  • Do not breathe through your nose. If you have problems breathing only through your mouth, use a nose clip (See Figure S).
  • Do not be concerned if liquid droplets form in the long connecting tube during treatment. When the nebulizer begins spitting, gently tap the nebulizer cup and continue breathing until the nebulizer cup is empty or stops making mist (See Figure T).
  • If you need to stop treatment before you are finished, or you begin coughing, turn off the compressor and do not spill any of the medicine.
  • To start treatment again, turn on the compressor and continue breathing slowly in and out through your mouth.
  • The complete treatment usually takes from 10 to 15 minutes for most nebulizers.
  • If you are using the Sidestream nebulizer, treatment usually takes from 2 to 6 minutes.
  • It is important to inhale the full dose of Pulmozyme. If you find a leak or feel any moisture coming from the nebulizer during treatment, turn off the compressor and check to make sure the nebulizer cap is sealed correctly before continuing (See Figure U).
If you are using the PARI BABY nebulizer to give Pulmozyme to your child, follow the instructions below in Step 14. If not, go to Step 15

Step 14. Breathing through the facemask.
  • During the treatment your child may sit, lie down or stand.
  • Place the facemask gently but firmly over your child's nose and mouth (See Figure V).
  • Make sure there are no air gaps between the mask and your child's face. This will help make sure that your child will get the full dose of Pulmozyme.
  • It is important that you try to keep the body of the nebulizer upright during the entire treatment (See Figure V). The elbow piece will allow you to move the mask for a good fit while keeping the nebulizer body upright.
  • When the nebulizer begins "spitting," gently tap the nebulizer cup and continue treatment until the nebulizer is empty or stops making a mist (See Figure W).
  • If you need to stop the treatment or your child begins to cough during treatment, turn the compressor off. Do not spill any Pulmozyme.
  • If you have not removed the mask and you want to begin the treatment again, turn on the compressor.
  • If you have removed the mask, repeat the steps above to replace the mask on your child's face and restart the compressor.
  • The complete treatment usually takes from 10 to 15 minutes.
It is important that your child inhale the full dose of Pulmozyme. If you find a leak or feel moisture coming from the nebulizer during the treatment, turn off the compressor and make sure the nebulizer cap is sealed correctly before starting the compressor again (See Figure X).
After your treatment with Pulmozyme:

Step 15. Prepare the nebulizer for cleaning and storage.
  • Turn off the compressor and take apart the nebulizer system. Set aside the flexible aerosol tube and the long connecting tube.

    Note: The Sidestream nebulizer does not use a flexible aerosol tube.
  • Throw away the Pulmozyme ampule in your household trash.
  • Follow the manufacturer's recommendations for care of your nebulizer and compressor.
How should I store Pulmozyme?

12.3 Pharmacokinetics

When 2.5 mg PULMOZYME was administered by inhalation to eighteen CF patients, mean sputum concentrations of 3 µg/mL DNase were measurable within 15 minutes. Mean sputum concentrations declined to an average of 0.6 µg/mL two hours following inhalation. Inhalation of up to 10 mg TID of PULMOZYME by 4 CF patients for six consecutive days, did not result in a significant elevation of serum concentrations of DNase above normal endogenous levels. After administration of up to 2.5 mg of PULMOZYME twice daily for six months to 321 CF patients, no accumulation of serum DNase was noted. Dornase alfa is expected to be metabolized by proteases present in biological fluids. A human intravenous dose study suggested an elimination half-life of 3-4 hours for dornase alfa.

PULMOZYME, 2.5 mg by inhalation, was administered daily to 98 patients aged 3 months to ≤ 10 years, and bronchoalveolar lavage (BAL) fluid was obtained within 90 minutes of the first dose. BAL DNase concentrations were detectable in all patients but showed a broad range, from 0.007 to 1.8 µg/mL. Over an average of 14 days of exposure, serum DNase concentrations (mean ± s.d.) increased by 1.1 ± 1.6 ng/mL for the 3 months to < 5 year age group and by 0.8 ± 1.2 ng/mL for the 5 to ≤ 10 year age group. The relationship between BAL or serum DNase concentration and adverse experiences and clinical outcomes is unknown.

2.1 Recommended Dosage

The recommended dosage, in most cystic fibrosis patients, is 2.5 mg (one single-dose ampule) inhaled once daily using a recommended jet nebulizer connected to an air compressor system or via a vibrating mesh nebulizer [see Dosage and Administration (2.2)].

Some patients may benefit from twice daily administration [see Clinical Studies (14)].

1 Indications and Usage

PULMOZYME® is indicated, in conjunction with standard therapies, for the management of pediatric and adult patients with cystic fibrosis (CF) to improve pulmonary function.

In CF patients with an FVC ≥ 40% of predicted, daily administration of PULMOZYME has also been shown to reduce the risk of respiratory tract infections requiring parenteral antibiotics.

12.1 Mechanism of Action

PULMOZYME is recombinant human deoxyribonuclease I (rhDNase), an enzyme which selectively cleaves DNA. In preclinical in vitro studies, PULMOZYME hydrolyzes the DNA in sputum of CF patients and reduces sputum viscoelasticity. In CF patients, retention of viscous purulent secretions in the airways contributes both to reduced pulmonary function and to exacerbations of infection. Purulent pulmonary secretions contain very high concentrations of extracellular DNA released by degenerating leukocytes that accumulate in response to infection.

5 Warnings and Precautions

None.

2 Dosage and Administration
  • The recommended dosage is 2.5 mg (one single-dose ampule) inhaled once daily using a recommended nebulizer. (2.1)
  • Some patients may benefit from twice daily administration. (2.1)
  • See full prescribing information for the recommended nebulizers for use with PULMOZYME. (2.2)
3 Dosage Forms and Strengths

Inhalation solution: 2.5 mg/2.5 mL (1 mg/mL) clear, colorless solution in single-dose ampules.

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 practice.

The data described below reflect exposure to PULMOZYME in 902 patients, with exposures ranging from 2 weeks of daily administration up to once or twice daily administration for six months. PULMOZYME was studied in both placebo-controlled (n=804) and uncontrolled trials (n=98). The population of patients in placebo-controlled trials was with FVC ≥ 40% of predicted (n=643) or with more advanced pulmonary disease, FVC < 40% of predicted (n=161). The population in the uncontrolled trial included 98 pediatric patients with CF ranging from 3 months to 10 years of age. More than half of the patients received PULMOZYME 2.5 mg by inhalation once a day (n=581), while the rest of patients (n=321) received PULMOZYME 2.5 mg by inhalation twice a day.

17 Patient Counseling Information

Advise patients to read the FDA-approved patient labeling (Instructions for Use).

16 How Supplied/storage and Handling

Do not use if the ampules are exposed to room temperature (22°C to 28°C [72°F to 82°F]) for more than a total of 60 hours. Avoid excessive heat and light.

11 Description (11 DESCRIPTION)

Dornase alfa is a recombinant human deoxyribonuclease I (rhDNase) an enzyme which selectively cleaves DNA. The protein is produced by genetically engineered Chinese Hamster Ovary (CHO) cells containing DNA encoding for the native human protein, deoxyribonuclease I (DNase). The product is purified by column chromatography and tangential flow filtration. The purified glycoprotein contains 260 amino acids with an approximate molecular weight of 37,000 daltons. The primary amino acid sequence is identical to that of the native human enzyme.

PULMOZYME (dornase alfa) inhalation solution is administered by inhalation of an aerosol mist produced by a compressed air driven nebulizer or a recommended nebulizer system [see Clinical Studies (14) and Dosage and Administration (2.2)]. PULMOZYME is a sterile, clear, colorless, highly purified solution in single-dose ampules. Each ampule delivers 2.5 mL of the solution to the nebulizer bowl. Each mL of aqueous solution contains 1 mg dornase alfa, calcium chloride dihydrate (0.15 mg) and sodium chloride (8.77 mg). The solution contains no preservative. The nominal pH of the solution is 6.3.

8.4 Pediatric Use

The safety and effectiveness of PULMOZYME in conjunction with standard therapies for cystic fibrosis have been established in pediatric patients. Use of PULMOZYME in pediatric patients is supported by evidence in the following age groups:

  • Patients 5 to 17 years of age: Use of PULMOZYME in patients 5 to 17 years of age is supported by evidence from a randomized, placebo-controlled trial of 303 of clinically stable cystic fibrosis patients 5 to 17 years of age who received PULMOZYME [see Clinical Studies (14)].
  • Patients less than 5 years: Use of PULMOZYME in patients less than 5 years of age is supported by extrapolation of efficacy data in patients 5 years of age and older with additional safety data in 65 pediatric patients aged 3 months to less than 5 years who received PULMOZYME 2.5 mg daily by inhalation for 2 weeks [see Adverse Reactions (6.1) and Clinical Studies (14)].
8.5 Geriatric Use

Cystic fibrosis is primarily a disease of children and young adults. Clinical studies of PULMOZYME did not include sufficient numbers of subjects aged 65 or older to determine whether they respond differently from younger subjects.

4 Contraindications (4 CONTRAINDICATIONS)

PULMOZYME is contraindicated in patients with known hypersensitivity to dornase alfa, Chinese Hamster Ovary cell products, or any component of the product.

6 Adverse Reactions (6 ADVERSE REACTIONS)

The most common adverse reactions (occurring in ≥3% of patients treated with PULMOZYME over placebo) seen in clinical trials in CF patients were: voice alteration, pharyngitis, rash, laryngitis, chest pain, conjunctivitis, rhinitis, decrease in FVC of ≥10%, fever, and dyspnea. (6.1)

Instructions for Use (INSTRUCTIONS FOR USE)

PULMOZYME® (PULL-muh-zyme)

(dornase alfa)

Inhalation Solution

This Instructions for Use contains information on how to use PULMOZYME with Jet Nebulizers and Compressors

See the other side of this Instructions for Use for information on use of Pulmozyme with the recommended vibrating mesh nebulizers

Read and understand this Instructions for Use and the nebulizer manufacturer's instruction manual before you start taking Pulmozyme and each time you get a refill. There may be new information. This information does not take the place of talking to your doctor about your medical condition or your treatment.

A nebulizer and a compressor are used together to give a dose of Pulmozyme. A nebulizer changes the Pulmozyme liquid medicine into a fine mist you inhale by breathing through a mouthpiece. A compressor gives the nebulizer power and makes the nebulizer work.

Pulmozyme should only be used with the approved nebulizers and appropriate compressors as recommended below, or with the recommended vibrating mesh nebulizers (see other side of this Instructions for Use). Read and follow the manufacturer's instruction manual.

Do not use any other inhaled medicines in the nebulizer at the same time. Keep all other inhaled medicine systems completely separate from Pulmozyme.

Use the mouthpiece or face mask provided with the nebulizer kit.

If your child cannot breathe in or breathe out by mouth, you may use the PARI BABY reusable nebulizer, but you should discuss it with your doctor first. The PARI BABY nebulizer is the same as the PARI LC Plus Jet system, except the mouthpiece is replaced by a tight-fitting face mask connected to an elbow piece.

Follow the steps on this side of the Instructions for Use to give Pulmozyme using the following jet nebulizer systems

Jet Nebulizer Compressor
Hudson T Up-draft II A compressor with the following specifications is recommended:
  • Approximate air flow of 3.5 L/min to 12 L/min at approximately 20 psi to 45 psi pressure
Marquest Acorn II
PARI LC Plus
PARI BABY
Durable Sidestream

For additional information on an appropriate compressor to use with Pulmozyme, read the manufacturer's instruction manual for the recommended nebulizer.

Preparing the jet nebulizer and compressor:

Step 1. Clean a flat table surface and wash your hands.
  • Clean a flat table surface.
  • Wash your hands well with soap and water before using the Pulmozyme ampule and nebulizer. This helps prevent infection (See Figure B).
Step 2. Gather the nebulizer and test the compressor.
  • Place the nebulizer parts on a clean, flat table surface within reach.
  • Test the compressor by turning it on and putting your finger in front of the "air out" or "air" port to feel air flowing. Turn off the compressor (See Figure C).
Step 3. Gather the Pulmozyme ampule and check the expiration date.
  • Remove 1 foil pouch of Pulmozyme from the refrigerator. Open the foil pouch and remove 1 ampule of Pulmozyme. Put the remaining ampules back in the foil pouch and return them to the refrigerator.
  • Check the expiration (exp.) date printed on the ampule (See Figure D).
  • Do not use the Pulmozyme ampule if the expiration date has passed.
Step 4. Check the Pulmozyme ampule.
  • Check the ampule for leaks by turning it upside down and gently squeezing (See Figure E).

    Do not use the ampule if it is leaking. Throw it away and get a new one.
  • Check the Pulmozyme liquid in the ampule and make sure it is clear and free of particles.
  • Do not use Pulmozyme if the liquid is cloudy or discolored. Take the Pulmozyme back to the pharmacy, hospital, or clinic that gave you the medicine.
Step 5. Attach the long connecting tube to the compressor.
  • Attach the long connecting tube to the "air out" or "air" port on the compressor (See Figure F).
Step 6. Attach the mouthpiece.
  • Skip to Step 7 if you use the Sidestream nebulizer or the PARI BABY nebulizer.
  • Push the mouthpiece into the wider end of the plastic T. Attach the flexible aerosol tube to the other end of the T (See Figure G).
Step 7. Remove the cap from the cup.
  • Unscrew or unsnap the cap from the nebulizer cup (See Figure H).
  • Put the nebulizer cup on the table face up and place the cap upside down on a clean surface (See Figure I).
Step 8. Open the Pulmozyme ampule.
  • Hold the tab at the bottom of the Pulmozyme ampule firmly. Twist off the top. Do not squeeze the body of the ampule (See Figure J).
Step 9. Pour the full Pulmozyme dose into the nebulizer cup.
  • Turn the ampule upside down and squeeze gently to empty the medicine into the nebulizer cup. Keep squeezing until the ampule is empty. It is very important you squeeze all of the medicine out of the ampule (See Figure K).
  • Screw or snap the cap onto the nebulizer cup (See Figure L).
Step 10. Connect the plastic T.
  • Connect the plastic T to the nebulizer cap (See Figure M).
  • If you are using the Sidestream nebulizer, attach the mouthpiece to the top of the nebulizer (See Figure N).
  • If you are using the PARI BABY nebulizer, connect the elbow piece and mask to the nebulizer outlet (See Figure O).
Step 11. Attach the long connecting tube to the cup.
  • Connect the open end of the long connecting tube to the port on the bottom of the nebulizer cup by pushing up firmly (See Figure P).
Step 12. Turn on the compressor.
  • Turn on the compressor and check to see that mist is coming out of the nebulizer (See Figure Q).
Taking your dose of Pulmozyme with a nebulizer:
Step 13. Breathe through the mouthpiece.
  • Skip to Step 14 if you are using the PARI BABY to give Pulmozyme to your child.
  • Place the mouthpiece between your teeth and on top of your tongue (See Figure R).
  • Breathe slowly in and out through your mouth. Do not block the airflow with your tongue.
  • Do not breathe through your nose. If you have problems breathing only through your mouth, use a nose clip (See Figure S).
  • Do not be concerned if liquid droplets form in the long connecting tube during treatment. When the nebulizer begins spitting, gently tap the nebulizer cup and continue breathing until the nebulizer cup is empty or stops making mist (See Figure T).
  • If you need to stop treatment before you are finished, or you begin coughing, turn off the compressor and do not spill any of the medicine.
  • To start treatment again, turn on the compressor and continue breathing slowly in and out through your mouth.
  • The complete treatment usually takes from 10 to 15 minutes for most nebulizers.
  • If you are using the Sidestream nebulizer, treatment usually takes from 2 to 6 minutes.
  • It is important to inhale the full dose of Pulmozyme. If you find a leak or feel any moisture coming from the nebulizer during treatment, turn off the compressor and check to make sure the nebulizer cap is sealed correctly before continuing (See Figure U).
If you are using the PARI BABY nebulizer to give Pulmozyme to your child, follow the instructions below in Step 14. If not, go to Step 15

Step 14. Breathing through the facemask.
  • During the treatment your child may sit, lie down or stand.
  • Place the facemask gently but firmly over your child's nose and mouth (See Figure V).
  • Make sure there are no air gaps between the mask and your child's face. This will help make sure that your child will get the full dose of Pulmozyme.
  • It is important that you try to keep the body of the nebulizer upright during the entire treatment (See Figure V). The elbow piece will allow you to move the mask for a good fit while keeping the nebulizer body upright.
  • When the nebulizer begins "spitting," gently tap the nebulizer cup and continue treatment until the nebulizer is empty or stops making a mist (See Figure W).
  • If you need to stop the treatment or your child begins to cough during treatment, turn the compressor off. Do not spill any Pulmozyme.
  • If you have not removed the mask and you want to begin the treatment again, turn on the compressor.
  • If you have removed the mask, repeat the steps above to replace the mask on your child's face and restart the compressor.
  • The complete treatment usually takes from 10 to 15 minutes.
It is important that your child inhale the full dose of Pulmozyme. If you find a leak or feel moisture coming from the nebulizer during the treatment, turn off the compressor and make sure the nebulizer cap is sealed correctly before starting the compressor again (See Figure X).
After your treatment with Pulmozyme:

Step 15. Prepare the nebulizer for cleaning and storage.
  • Turn off the compressor and take apart the nebulizer system. Set aside the flexible aerosol tube and the long connecting tube.

    Note: The Sidestream nebulizer does not use a flexible aerosol tube.
  • Throw away the Pulmozyme ampule in your household trash.
  • Follow the manufacturer's recommendations for care of your nebulizer and compressor.
How should I store Pulmozyme?

12.3 Pharmacokinetics

When 2.5 mg PULMOZYME was administered by inhalation to eighteen CF patients, mean sputum concentrations of 3 µg/mL DNase were measurable within 15 minutes. Mean sputum concentrations declined to an average of 0.6 µg/mL two hours following inhalation. Inhalation of up to 10 mg TID of PULMOZYME by 4 CF patients for six consecutive days, did not result in a significant elevation of serum concentrations of DNase above normal endogenous levels. After administration of up to 2.5 mg of PULMOZYME twice daily for six months to 321 CF patients, no accumulation of serum DNase was noted. Dornase alfa is expected to be metabolized by proteases present in biological fluids. A human intravenous dose study suggested an elimination half-life of 3-4 hours for dornase alfa.

PULMOZYME, 2.5 mg by inhalation, was administered daily to 98 patients aged 3 months to ≤ 10 years, and bronchoalveolar lavage (BAL) fluid was obtained within 90 minutes of the first dose. BAL DNase concentrations were detectable in all patients but showed a broad range, from 0.007 to 1.8 µg/mL. Over an average of 14 days of exposure, serum DNase concentrations (mean ± s.d.) increased by 1.1 ± 1.6 ng/mL for the 3 months to < 5 year age group and by 0.8 ± 1.2 ng/mL for the 5 to ≤ 10 year age group. The relationship between BAL or serum DNase concentration and adverse experiences and clinical outcomes is unknown.

2.1 Recommended Dosage

The recommended dosage, in most cystic fibrosis patients, is 2.5 mg (one single-dose ampule) inhaled once daily using a recommended jet nebulizer connected to an air compressor system or via a vibrating mesh nebulizer [see Dosage and Administration (2.2)].

Some patients may benefit from twice daily administration [see Clinical Studies (14)].

1 Indications and Usage (1 INDICATIONS AND USAGE)

PULMOZYME® is indicated, in conjunction with standard therapies, for the management of pediatric and adult patients with cystic fibrosis (CF) to improve pulmonary function.

In CF patients with an FVC ≥ 40% of predicted, daily administration of PULMOZYME has also been shown to reduce the risk of respiratory tract infections requiring parenteral antibiotics.

12.1 Mechanism of Action

PULMOZYME is recombinant human deoxyribonuclease I (rhDNase), an enzyme which selectively cleaves DNA. In preclinical in vitro studies, PULMOZYME hydrolyzes the DNA in sputum of CF patients and reduces sputum viscoelasticity. In CF patients, retention of viscous purulent secretions in the airways contributes both to reduced pulmonary function and to exacerbations of infection. Purulent pulmonary secretions contain very high concentrations of extracellular DNA released by degenerating leukocytes that accumulate in response to infection.

5 Warnings and Precautions (5 WARNINGS AND PRECAUTIONS)

None.

2 Dosage and Administration (2 DOSAGE AND ADMINISTRATION)
  • The recommended dosage is 2.5 mg (one single-dose ampule) inhaled once daily using a recommended nebulizer. (2.1)
  • Some patients may benefit from twice daily administration. (2.1)
  • See full prescribing information for the recommended nebulizers for use with PULMOZYME. (2.2)
3 Dosage Forms and Strengths (3 DOSAGE FORMS AND STRENGTHS)

Inhalation solution: 2.5 mg/2.5 mL (1 mg/mL) clear, colorless solution in single-dose ampules.

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 practice.

The data described below reflect exposure to PULMOZYME in 902 patients, with exposures ranging from 2 weeks of daily administration up to once or twice daily administration for six months. PULMOZYME was studied in both placebo-controlled (n=804) and uncontrolled trials (n=98). The population of patients in placebo-controlled trials was with FVC ≥ 40% of predicted (n=643) or with more advanced pulmonary disease, FVC < 40% of predicted (n=161). The population in the uncontrolled trial included 98 pediatric patients with CF ranging from 3 months to 10 years of age. More than half of the patients received PULMOZYME 2.5 mg by inhalation once a day (n=581), while the rest of patients (n=321) received PULMOZYME 2.5 mg by inhalation twice a day.

17 Patient Counseling Information (17 PATIENT COUNSELING INFORMATION)
