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.”

New therapy attacks the source of asthma, treats the disease at cellular level

Imagine you suffer from severe asthma, and you've tried every treatment available, but nothing has worked. You still can't breathe. Then a new therapy comes along that attacks the source of the asthma, as opposed to the symptoms, and treats the disease at a cellular level. That's the promise of biologics, and the topic of four presentations at the 2015 ACAAI Annual Scientific Meeting in San Antonio, November 5-9.

"Biologics is definitely something that has piqued the interest of physicians, including allergists, throughout medicine," said Kevin Murphy, MD, ACAAI Fellow and presenter at the meeting. "Traditional asthma treatments don't work for some people, and their asthma is uncontrolled. Biologics is at the cutting edge of treatment because it has the potential to be personalized - to be formulated to treat those cells which are the mechanism, or pathway, that leads to allergic inflammation and makes it so hard for some people to breathe."

Omalizumab is currently the only biologic treatment for asthma that has been approved by the Food and Drug Administration (FDA) for use in the United States, but more are in the pipeline. Allergists hope that in the next few years there could be two or three more drugs approved. Omalizumab is safe for both adults, and children over the age of 12, for treatment of severe asthma.

"It's an exciting time to be an allergist," said allergist Rohit Katial, MD, ACAAI Fellow and presenter at the meeting. "For many years, our primary tools for combatting severe asthma have been either bronchodilators, known as quick-relief medicines, or long-term control medicines which are taken every day to prevent symptoms and attacks. We also use immunotherapy, allergy shots, to reduce the allergic reactions which cause asthma attacks. Biologics target the cells and pathways that cause the allergic inflammation that has been linked to asthma."

Nearly five million asthmatics worldwide could benefit from antifungal therapy

Clinical studies have shown that oral antifungal drugs significantly improve symptoms and asthma control in asthmatics with ABPA, treatment endorsed by the Cochrane Collaboration. This is the first time that a global estimate of ABPA numbers has been made.

In national league tables of asthma rates in adults, only Australia and Sweden have a higher prevalence than the UK. In global league tables of ABPA occurrence, New Zealand tops the list with a 3.5% rate in new patients attending chest clinics at hospitals. The rates were 2.6% in Cape Town, 2.3% in Saudi Arabia, 2.5% in China and 0.7% in an older study from Ireland. No population-based studies have been done.

Itraconazole

Posaconazole

Voriconazole

In addition to standard asthma therapy, the antifungal therapy used is itraconazole  now a generic, inexpensive antifungal  with a response rate of 60%. The researchers also found that antifungal therapy also benefits patients with severe asthma sensitized to fungi, called SAFS.

Alternatives include voriconazole and posaconazole, which have 75-80% response rates. In a recent assessment of voriconazole and posaconazole for both ABPA and SAFS, 75% of patients were able to stop taking oral corticosteroids, a major benefit, and 38% of patients had their asthma severity downgraded on antifungal therapy.

Professor David Denning, professor of medicine and medical mycology at the University of Manchester and Director of the University Hospital of South Manchester's National Aspergillosis Centre, led the study into the total number of asthmatics worldwide. He said the study results implied that asthma admissions and deaths could be avoided with more extensive use of antifungal therapy.

"We were surprised by the number of patients with ABPA, and by the lack of community based studies done," he said. "Our National Aspergillosis Centre treats hundreds of these patients each year, generally with major improvement, and so a conscious program to seek out ABPA from all asthmatics is required."

Professor Donald Cole of the Dalla Lana School of Public Health at the University of Toronto was the senior author of the study and contributed his expert epidemiological knowledge to the development of the model and provided a 'reality' check of the model's estimates.

Formoterol drug improves fat burning and protein metabolism in men

We know that, Formoterol  or eformoterol  is a long-acting β₂-agonist used in the management of asthma and/or chronic obstructive pulmonary disease (COPD). It is marketed in four forms: a dry-powder inhaler (DPI), a metered-dose inhaler (MDI), an oral tablet, and an inhalation solution, under various trade names including Foradil/Foradile (Schering-Plough in the U.S., Novartis rest of world), Oxeze (AstraZeneca), Atock (Astellas), Atimos Modulite (Trinity-Chiesi), and Perforomist (Dey).

Now researchers lead by Dr. Paul Lee of  Garvan Institute of Medical Research in Sydney, have for the first time reports that research in animals has shown that formoterol can stimulate the growth of muscle and the burning of fat...

Asthma Drug Prevents Spread of Breast Cancer, Study Finds......

We know that. Tranilast (structure, brand name Rizaben) is an antiallergic drug. It was developed by Kissei Pharmaceuticals and was approved in 1982 for use in Japan and South Korea for bronchial asthma. Indications for keloid and hypertrophic scar were added in 1993. It has been used for the treatment of allergic disorders such as asthma, allergic rhinitis and atopic dermatitis. It has been also reported that it reduces (in-vitro) collagen synthesis in fibroblasts, inhibits the growth of neurofibroma cells and inhibits ( in-vitro) the production of interleukin-6 in endothelial cells.

Now researchers from St. Michael's Hospital, Canada reports that the drug to stop the spread of breast cancer cells traditionally resistant to chemotherapy.

Researchers grew breast cancer stem cells, which give rise to other cancer cells, in culture. The cells were injected into two groups of mice, including one group, which was also treated with tranilast. Dr. Prud'homme and his colleagues found the drug reduced growth of the primary cancerous tumour by 50 per cent and prevented the spread of the cancer to the lungs. Researchers also identified a molecule in the cancer cell that binds to tranilast and appears to be responsible for this anti-cancer effect.

As per the researchers 'Tranilast' binds to a molecule known as the aryl hydrocarbon receptor (AHR), which regulates cell growth and some aspects of immunity. This makes the drug beneficial in treating allergies, inflammatory diseases and cancer.

"For the first time, we were able to show that tranilast shows promise for breast cancer treatment in levels commonly well-tolerated by patients who use the drug for other medical conditions," Dr. Prud'homme said. "These results are very encouraging and we are expanding our studies. Further studies are necessary to determine if the drug is effective against different types of breast and other cancers, and its interaction with anti-cancer drugs.........
