Airsupra (albuterol/budesonide), formerly known as PT027, has been approved in the US for the as-needed treatment or prevention of bronchoconstriction and to reduce the risk of exacerbations in people with asthma aged 18 years and older.

The approval by the Food and Drug Administration (FDA) was based on results from the MANDALA and DENALI Phase III trials. In MANDALA, Airsupra significantly reduced the risk of severe exacerbations compared to albuterol in patients with moderate to severe asthma when used as an as-needed rescue medication in response to symptoms. Importantly, in the secondary endpoint of mean annualised total systemic corticosteroid exposure, Airsupra demonstrated a significant reduction compared to albuterol at the approved dose of 180mcg albuterol/160mcg budesonide. In DENALI, Airsupra significantly improved lung function compared to the individual components albuterol and budesonide in patients with mild to moderate asthma.

Airsupra is a first-in-class, pressurised metered-dose inhaler (pMDI), fixed-dose combination rescue medication containing albuterol, a short-acting beta2-agonist (SABA), and budesonide, an anti-inflammatory inhaled corticosteroid (ICS) in the US. It is being developed by AstraZeneca and Avillion.

Bradley E. Chipps, Past President of the American College of Allergy, Asthma & Immunology and Medical Director of Capital Allergy & Respiratory Disease Center in Sacramento, US, said: “People with asthma are at risk of severe exacerbations regardless of their disease severity or level of control. Current albuterol rescue inhalers alleviate acute symptoms, but do not treat the underlying inflammation in asthma. The approval of Airsupra means that for the first time, adults with asthma in the US have a rescue treatment to manage both their symptoms and the inflammatory nature of their disease.”

Mene Pangalos, Executive Vice President, BioPharmaceuticals R&D, AstraZeneca, said: “With patients experiencing more than 10 million asthma exacerbations each year in the US and uncontrolled asthma expected to cost the US economy billions of dollars in direct medical costs alone over the next 20 years, today’s positive decision is good news for those adults with asthma who make up more than 80% of asthma patients in the US. Physicians will be able to offer their patients Airsupra, an important new rescue treatment that reduces the risk of asthma exacerbations.”

Asthma is a chronic, inflammatory respiratory disease with variable symptoms that affects as many as 262 million people worldwide. In the US over 21 million adults have asthma, representing more than 80% of the total number of people with asthma. Adults have 8.5 million exacerbations each year in the US. Uncontrolled asthma will cost the US economy an estimated $300 billion (in 2018 dollar values) in the next 20 years in direct medical costs alone.

The safety and tolerability of Airsupra in both trials were consistent with the known profiles of the components,1,2 with the most common adverse events including headache, oral candidiasis, cough and dysphonia.

FDA Approves Airsupra (albuterol/budesonide) Metered-Dose Inhaler to Reduce the Risk of Asthma Exacerbations

FDA Approves ProAir Digihaler (albuterol sulfate) as the First and Only Digital Inhaler with Built-In Sensors

In continuation of my update on albuterol

Teva Pharmaceutical Industries Ltd., announced  that the U.S. Food and Drug Administration (FDA) has approved ProAir ® Digihaler™ (albuterol sulfate 117 mcg) inhalation powder, the first and only digital inhaler with built-in sensors which connects to a companion mobile application and provides inhaler use information to people with asthma and COPD. ProAir ® Digihaler™ is indicated for the treatment or prevention of bronchospasm in patients aged four years and older with reversible obstructive airway disease, and for prevention of exercise-induced bronchospasm (EIB) in patients aged four years and older.

“This approval marks a significant milestone not only for Teva, but for the respiratory community as it allows patients and their caregivers to better understand inhaler usage through digital technology,” said Sven Dethlefs, Executive Vice President, Global Marketing & Portfolio. “Teva recognizes the importance of integrating technology into patient care, and we are very proud to lead the way with the approval of ProAir ® Digihaler™. The digital technology built into ProAir ® Digihaler™ provides patients with data on their inhaler use, which may help them to have a more informed dialogue with their healthcare provider regarding their asthma or COPD management.”

ProAir ® Digihaler™ contains built-in sensors that detect when the inhaler is used and measure inspiratory flow. This inhaler-use data is then sent to the companion mobile app using Bluetooth ® Wireless Technology so patients can review their data over time, and if desired, share it with their healthcare professionals.

“There are 25 million Americans living with asthma1, many of whom use inhalers as part of their treatment regimen. Despite advancements in care over the years, we know that many are using their rescue medications incorrectly2 or too often3,” said Tonya Winders, President & CEO of the Allergy & Asthma Network. “The FDA approval of ProAir ® Digihaler ™ is significant because it may help patients track their inhaler usage and provide data that can be used to work more closely with their HCPs on their asthma management. This approval is a major step forward and is indicative of how medications are evolving through technological innovations.”

The approval of ProAir ® Digihaler™ is based on the review of a supplemental new drug application (sNDA) submitted by Teva to the FDA. ProAir ® Digihaler™ combines a breath-activated, multi-dose dry powder inhaler with albuterol, the most widely used asthma rescue medication, with a built-in electronic module and a companion mobile app.

“One of the challenges physicians are faced with in caring for their asthma and COPD patients is knowing if their patients are using their inhaled medication as they should. That’s what makes a product like this so important to doctor-patient discussions,” said Tushar Shah, M.D., Global Head of Specialty Clinical Development & Medical Affairs at Teva Pharmaceuticals. “Offering a tool that enables doctors to see data on their patients’ inhaler usage will allow them to have more productive conversations about identifying issues and how to manage their illness.”

Teva Announces FDA Approval of ProAir RespiClick (albuterol sulfate) Inhalation Powder for Pediatric Asthma Patients Ages 4 to 11

Teva Pharmaceutical Industries Ltd.,  announced  that the U.S. Food and Drug Administration (FDA) has approved ProAir RespiClick (albuterol sulfate) Inhalation Powder for the treatment or prevention of bronchospasm in children 4 to 11 years of age with reversible obstructive airway disease and for the prevention of exercise-induced bronchospasm (EIB).

ProAir RespiClick was approved by the FDA for use in patients 12 years of age and older in March 2015 and remains the only breath-activated, multi-dose, dry powder, short-acting beta-agonist (SABA) inhaler available in the U.S.

Drug discovery study identifies promising new compound to open constricted airways

Despite the progress made in managing asthma and chronic obstructive pulmonary disease (COPD), poorly controlled symptoms for both respiratory diseases can lead to severe shortness of breath, hospitalizations or even death.

"Only about 50 percent of asthmatics, and an even lower percentage of people with COPD, achieve adequate control of lung inflammation and airway constriction with currently available medications," said Stephen Liggett, MD, vice dean for research at the University of South Florida Morsani College of Medicine and a USF Health professor of medicine, molecular pharmacology and physiology, and biomedical engineering. "So, we're clearly missing something from our drug armamentarium to help all these patients."

Dr. Liggett's laboratory has discovered several subtypes of bitter taste receptors (TAS2Rs) -- G protein-coupled receptors expressed on human smooth airway muscle cells deep inside the lungs. In asthma and COPD, tightening of smooth muscles surrounding bronchial tubes narrows the airway and reduces air flow, and Dr Liggett's lab found that these taste receptors open the airway when activated. They are now looking for new drugs to treat asthma and other obstructive lung diseases by targeting smooth muscle TAS2Rs to open constricted airways.

A promising bronchodilator agonist rises to the top

In a preclinical study published Nov. 5 in ACS Pharmacology and Translational Science, Dr. Liggett and colleagues identified and characterized 18 new compounds (agonists) that activate bitter taste receptor subtype TAS2R5 to promote relaxation (dilation) of human airway smooth muscle cells. The cross-disciplinary team found 1,10 phenanthroline-5,6-dione (T5-8 for short) to be the most promising of several lead compounds (drug candidates). T5-8 was 1,000 times more potent than some of the other compounds tested, and it demonstrated marked effectiveness in human airway smooth muscle cells grown in the laboratory.

For this drug discovery project, Dr. Liggett's laboratory collaborated with Jim Leahy, PhD, professor and chair of chemistry at the USF College of Arts and Sciences, and Steven An, PhD, professor of pharmacology at the Rutgers Robert Wood Johnson Medical School.

In an extensive screening conducted previously, another research group identified only one compound that would bind to and specifically activate the TASR5 bitter taste receptor -- although apparently with limited effectiveness. Using this particular agonist (called T5-1 in the paper) as a starting point, the team relied on their collective disciplines to devise new activators, aiming for a much better drug profile for administration to humans.

"The two key questions we asked were: 'Is it possible to find a more potent agonist that activates this receptor?' and 'Is it feasible to deliver by inhalation given the potencies that we find?'" said Dr. Liggett, the paper's senior author. "T5-8 was the bronchodilator agonist that worked best. There were a few others that were very good as well, so we now have multiple potential new drugs to carry out the next steps."

The researchers developed screening techniques to determine just how potent and effective the 18 compounds were. A biochemical test assessed how well these new agonists activated TAS2R5 in airway smooth muscle cells isolated from non-asthmatic human donor lungs. Then, the researchers validated the effect on airway smooth muscle relaxation using a technique known as magnetic twisting cytometry, pioneered by Dr An.

"Team science" solves a structural problem

"The biggest challenge we faced was not having a 3-D crystal structure of TAS2R5, so we had no idea exactly how agonist T5-1 fit into this mysterious bitter taste receptor," Dr. Liggett said. "By merging our strength in receptors, pharmacology, physiology, and drug development, our team was able to make the breakthrough."

T5-8 was superior to all the other bronchodilator agonists screened, exhibiting a maximum relaxation response (50%) substantially greater than that of albuterol (27%). Albuterol belongs to the only class of direct bronchodilators (beta-2 agonists) available to treat wheezing and shortness of breath caused by asthma and COPD. However, this drug or its derivatives, often prescribed as a rescue inhaler, does not work for all patients and overuse has been linked to increased hospitalizations, Dr. Liggett said. "Having two distinct classes of drugs that work in different ways to open the airways would be an important step to help patients optimally control their symptoms."

The ACS Pharmacology paper highlights the importance of translational research in bridging the gap between laboratory discoveries and new therapies to improve human health, he added. "This study yielded a drug discovery that successfully meets most of the criteria needed to advance the compound toward its first trial as a potential first-in-class bronchodilator targeting airway receptor TAS2R5."

Drug discovery study identifies promising new compound to open constricted airways  

FDA Approves AirDuo Digihaler (fluticasone propionate and salmeterol) Inhalation Powder for Asthma

In continuation of my update on (fluticasone propionate and salmeterol

   

Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) announced today that the U.S. Food and Drug Administration (FDA) has approved AirDuo® Digihaler™ (fluticasone propionate 113 mcg and salmeterol 14 mcg) Inhalation Powder, a combination therapy digital inhaler with built-in sensors that connects to a companion mobile application to provide information on inhaler use to people with asthma. AirDuo Digihaler is indicated for the treatment of asthma in patients aged 12 years and older. AirDuo Digihaler is not used to relieve sudden breathing problems and won’t replace a rescue inhaler.

“We are thrilled to be able to expand our Digihaler™ portfolio to now include a maintenance treatment,” said Tushar Shah, M.D., Global Head of Specialty Clinical Development at Teva Pharmaceuticals. “With this approval, patients can now track how frequently they are using their inhalers. Granting patients the ability to track their maintenance inhaler use may help inform conversations with their doctors about treatment adherence and proper technique.”

Like ProAir® Digihaler™ (albuterol sulfate 117 mcg) inhalation powder, indicated for the treatment or prevention of bronchospasm in patients aged four years and older with reversible obstructive airway disease, and for prevention of exercise-induced bronchospasm (EIB) in patients four years and older, AirDuo® Digihaler™ contains built-in sensors that detect when the inhaler is used and measure inspiratory flow rates. This data is then sent to a companion mobile app using Bluetooth® Wireless Technology so that patients can review their data over time, and if desired, share it with their healthcare providers. Patients can also schedule reminders on their smartphone to take their AirDuo® Digihaler™ as prescribed.

“Even the most diligent asthma patients may not realize they are not following their treatment regimen, despite their best efforts,” said Dr. Nabeel Farooqui, MD, FAAAAI, FACAAI, Assistant Professor, Department of Medicine, Indiana University School of Medicine. “The ability to now measure their inspiratory flow rates and track their maintenance medication use, as well as the frequency with which they use their inhaler, may provide important data and insights to help inform treatment discussions with physicians. As a doctor, it’s exciting that my patients are able to share this type of information with me.”

The approval of AirDuo Digihaler is based on the review of the supplemental new drug application (sNDA) submitted by Teva to the FDA. AirDuo Digihaler combines a breath-actuated, multi-dose dry powder inhaler with fluticasone propionate, an inhaled corticosteroid (ICS) medicine that may help to decrease inflammation in the lungs, which can lead to breathing problems, and salmeterol, a long acting beta2 adrenergic agonist (LABA), which helps the muscles around the airways in the lungs stay relaxed in order to prevent symptoms. AirDuo Digihaler contains salmeterol. LABA medicines such as salmeterol when used alone increase the risk of hospitalizations and death from asthma problems. AirDuo Digihaler contains an ICS and a LABA. When an ICS and a LABA are used together, there is not a significant increased risk in hospitalizations and death from asthma problems.

AirDuo Digihaler was approved in a low, medium and high dose: 55/14 mcg, 113/14 mcg and 232/14 mcg administered as one inhalation twice daily. As a fixed dose combination asthma therapy containing an ICS and a LABA, AirDuo Digihaler contains the same active ingredients as Advair Diskus, which is also approved in low, medium and high doses: 100/50 mcg, 250/50 mcg and 500/50 mcg.

“For the 25 million Americans living with asthma1, advancements like this one are important and could help patients track their inhaler use and frequency,” said Tonya Winders, President & CEO of the Allergy & Asthma Network. “Allowing patients access to both their rescue and maintenance inhaler use information on their smartphones is a promising step towards potentially fostering greater discussions about asthma management.”

“The approval of AirDuo Digihaler is an important step for Teva and the respiratory community to create a technology platform for use in asthma management along with the previously-approved ProAir Digihaler,” said Sven Dethlefs, Executive Vice President, Global Marketing & Portfolio. “This technology aims at delivering innovations through cloud-based services with the target to provide new insights to guide treatment choices for caregivers to help them improve outcomes for asthma patients.”
