BRIDGEWATER, N.J., April 9, 2019 /PRNewswire/ -- Insmed
Incorporated (Nasdaq:INSM), a global biopharmaceutical company on a
mission to transform the lives of patients with serious and rare
diseases, today announced that the U.S. Patent and Trademark Office
(USPTO) has issued patent No. 10,251,900 for certain uses of
ARIKAYCE (amikacin liposome inhalation suspension). The claims of
the patent relate in part to methods for treating Mycobacterium
avium complex (MAC) lung disease via administration of ARIKAYCE
to patients previously unresponsive to MAC therapy. This is the
10th patent issued by the USPTO for ARIKAYCE in
MAC lung disease and the second with an expiry date of
May 15, 2035.
ARIKAYCE was granted accelerated approval by the U.S. Food and
Drug Administration on September 28,
2018, for the treatment of MAC lung disease as part of a
combination antibacterial drug regimen for adult patients who have
limited or no alternative treatment options.
"We are very pleased to receive another patent for ARIKAYCE that
reinforces our exclusivity in the U.S. to 2035 for methods that
align closely with our approved label, further strengthening
our global patent portfolio," said Will
Lewis, Chairman and Chief Executive Officer of Insmed. "In
addition, as we advance toward regulatory filings for ARIKAYCE in
Europe and Japan, we are continuing to pursue
intellectual property protection in these and other major markets
worldwide."
The methods described in the new U.S. patent relate in part to
the treatment of MAC lung infections in patients previously
unresponsive to MAC therapy, where the treatment includes achieving
a negative MAC sputum culture in the patient. The methods entail
administering ARIKAYCE to the patient in combination with a
macrolide antibiotic and ethambutol.
In addition to 10 U.S. patents, Insmed's global patent portfolio
includes eight issued/allowed patents for ARIKAYCE in Japan and five in Europe, with patent protection secured to 2033
and 2035, respectively.
About MAC Lung Disease
Mycobacterium avium complex (MAC) lung disease is a
rare and serious disorder that can significantly increase morbidity
and mortality. Patients with MAC lung disease can experience a
range of symptoms that often worsen over time, including chronic
cough, dyspnea, fatigue, fever, weight loss, and chest pain. In
some cases, MAC lung disease can cause severe, even permanent
damage to the lungs, and can be fatal.
MAC lung disease is an emerging public health concern worldwide
with significant unmet need. Current guideline-based treatment
involves the use of multi-drug regimens that are not specifically
approved for MAC lung disease. The course of treatment is often two
years or more and is inadequate in treating the disease in many
patients.
About ARIKAYCE (amikacin liposome inhalation
suspension)
ARIKAYCE is the first and only FDA-approved therapy indicated
for the treatment of Mycobacterium avium complex
(MAC) lung disease as part of a combination antibacterial drug
regimen for adult patients with limited or no alternative treatment
options. ARIKAYCE is a novel, inhaled, once-daily formulation
of amikacin, an established antibiotic that was historically
administered intravenously and associated with severe toxicity to
hearing, balance, and kidney function. Insmed's proprietary
PULMOVANCE™ liposomal technology enables the delivery of amikacin
directly to the lungs, where liposomal amikacin is taken up by lung
macrophages where the infection resides. This approach prolongs the
release of amikacin in the lungs while limiting systemic exposure.
ARIKAYCE is administered once daily using the
Lamira® Nebulizer System manufactured by PARI
Pharma GmbH (PARI).
About PARI Pharma and the Lamira Nebulizer System
ARIKAYCE® (amikacin liposome inhalation
suspension) is delivered by a novel inhalation device, the
Lamira Nebulizer System, developed by PARI. Lamira is a
quiet, portable nebulizer that enables efficient aerosolization of
liquid medications, including liposomal formulations such as
ARIKAYCE, via a vibrating, perforated membrane. Based on PARI's
100-year history working with aerosols, PARI is dedicated to
advancing inhalation therapies by developing innovative delivery
platforms and new pharmaceutical formulations that work together to
improve patient care.
IMPORTANT SAFETY INFORMATION
WARNING: RISK OF
INCREASED RESPIRATORY ADVERSE REACTIONS
|
ARIKAYCE has been
associated with an increased risk of respiratory adverse reactions,
including hypersensitivity pneumonitis, hemoptysis, bronchospasm,
and exacerbation of underlying pulmonary disease that have led to
hospitalizations in some cases.
|
Hypersensitivity Pneumonitis has been reported with
the use of ARIKAYCE in the clinical trials. Hypersensitivity
pneumonitis (reported as allergic alveolitis, pneumonitis,
interstitial lung disease, allergic reaction to ARIKAYCE) was
reported at a higher frequency in patients treated with ARIKAYCE
plus background regimen (3.1%) compared to patients treated with a
background regimen alone (0%). Most patients with hypersensitivity
pneumonitis discontinued treatment with ARIKAYCE and received
treatment with corticosteroids. If hypersensitivity pneumonitis
occurs, discontinue ARIKAYCE and manage patients as medically
appropriate.
Hemoptysis has been reported with the use of
ARIKAYCE in the clinical trials. Hemoptysis was reported at a
higher frequency in patients treated with ARIKAYCE plus background
regimen (17.9%) compared to patients treated with a background
regimen alone (12.5%). If hemoptysis occurs, manage patients as
medically appropriate.
Bronchospasm has been reported with the use of
ARIKAYCE in the clinical trials. Bronchospasm (reported as asthma,
bronchial hyperreactivity, bronchospasm, dyspnea, dyspnea
exertional, prolonged expiration, throat tightness, wheezing) was
reported at a higher frequency in patients treated with ARIKAYCE
plus background regimen (28.7%) compared to patients treated with a
background regimen alone (10.7 %). If bronchospasm occurs during
the use of ARIKAYCE, treat patients as medically
appropriate.
Exacerbations of underlying pulmonary disease has
been reported with the use of ARIKAYCE in the clinical trials.
Exacerbations of underlying pulmonary disease (reported as chronic
obstructive pulmonary disease (COPD), infective exacerbation of
COPD, infective exacerbation of bronchiectasis) have been reported
at a higher frequency in patients treated with ARIKAYCE plus
background regimen (14.8%) compared to patients treated with
background regimen alone (9.8%). If exacerbations of
underlying pulmonary disease occur during the use of ARIKAYCE,
treat patients as medically appropriate.
Ototoxicity has been reported with the use of
ARIKAYCE in the clinical trials. Ototoxicity (including deafness,
dizziness, presyncope, tinnitus, and vertigo) were reported with a
higher frequency in patients treated with ARIKAYCE plus background
regimen (17 %) compared to patients treated with background regimen
alone (9.8%). This was primarily driven by tinnitus (7.6% in
ARIKAYCE plus background regimen vs 0.9% in the background regimen
alone arm) and dizziness (6.3% in ARIKAYCE plus background regimen
vs 2.7% in the background regimen alone arm). Closely monitor
patients with known or suspected auditory or vestibular dysfunction
during treatment with ARIKAYCE. If ototoxicity occurs, manage
patients as medically appropriate, including potentially
discontinuing ARIKAYCE.
Nephrotoxicity was observed during the clinical
trials of ARIKAYCE in patients with MAC lung disease but not at a
higher frequency than background regimen alone. Nephrotoxicity has
been associated with the aminoglycosides. Close monitoring of
patients with known or suspected renal dysfunction may be needed
when prescribing ARIKAYCE.
Neuromuscular Blockade: Patients with neuromuscular
disorders were not enrolled in ARIKAYCE clinical trials. Patients
with known or suspected neuromuscular disorders, such as myasthenia
gravis, should be closely monitored since aminoglycosides may
aggravate muscle weakness by blocking the release of acetylcholine
at neuromuscular junctions.
Embryo-Fetal Toxicity: Aminoglycosides can cause fetal
harm when administered to a pregnant woman. Aminoglycosides,
including ARIKAYCE, may be associated with total, irreversible,
bilateral congenital deafness in pediatric patients
exposed in utero. Patients who use ARIKAYCE during
pregnancy, or become pregnant while taking ARIKAYCE should be
apprised of the potential hazard to the fetus.
Contraindications: ARIKAYCE is contraindicated in
patients with known hypersensitivity to any aminoglycoside.
Most Common Adverse Reactions: The most common adverse
reactions in Trial 1 at an incidence ≥5% for patients using
ARIKAYCE plus background regimen compared to patients treated with
background regimen alone were dysphonia (47% vs 1%), cough (39% vs
17%), bronchospasm (29% vs 11%), hemoptysis (18% vs 13%),
ototoxicity (17% vs 10%), upper airway irritation (17% vs 2%),
musculoskeletal pain (17% vs 8%), fatigue and asthenia (16% vs
10%), exacerbation of underlying pulmonary disease (15% vs 10%),
diarrhea (13% vs 5%), nausea (12% vs 4%), pneumonia (10% vs 8%),
headache (10% vs 5%), pyrexia (7% vs 5%), vomiting (7% vs 4%), rash
(6% vs 2%), decreased weight (6% vs 1%), change in sputum (5% vs
1%), and chest discomfort (5% vs 3%).
Drug Interactions: Avoid concomitant use of ARIKAYCE with
medications associated with neurotoxicity, nephrotoxicity, and
ototoxicity. Some diuretics can enhance aminoglycoside toxicity by
altering aminoglycoside concentrations in serum and tissue. Avoid
concomitant use of ARIKAYCE with ethacrynic acid, furosemide, urea,
or intravenous mannitol.
Overdosage: Adverse reactions specifically associated
with overdose of ARIKAYCE have not been identified. Acute toxicity
should be treated with immediate withdrawal of ARIKAYCE, and
baseline tests of renal function should be undertaken. Hemodialysis
may be helpful in removing amikacin from the body. In all cases of
suspected overdosage, physicians should contact the Regional Poison
Control Center for information about effective treatment.
INDICATION
LIMITED POPULATION: ARIKAYCE® is indicated in
adults, who have limited or no alternative treatment options, for
the treatment of Mycobacterium avium complex (MAC)
lung disease as part of a combination antibacterial drug regimen in
patients who do not achieve negative sputum cultures after a
minimum of 6 consecutive months of a multidrug background regimen
therapy. As only limited clinical safety and effectiveness data for
ARIKAYCE are currently available, reserve ARIKAYCE for use in
adults who have limited or no alternative treatment
options. This drug is indicated for use in a limited
and specific population of patients.
This indication is approved under accelerated approval based on
achieving sputum culture conversion (defined as 3 consecutive
negative monthly sputum cultures) by Month 6. Clinical benefit has
not yet been established. Continued approval for this indication
may be contingent upon verification and description of clinical
benefit in confirmatory trials.
Limitation of Use: ARIKAYCE has only been studied in
patients with refractory MAC lung disease defined as patients who
did not achieve negative sputum cultures after a minimum of 6
consecutive months of a multidrug background regimen therapy. The
use of ARIKAYCE is not recommended for patients with non-refractory
MAC lung disease.
Patients are encouraged report negative side effects of
prescription drugs to the FDA.
