CAMBRIDGE, England, September 10, 2017 /PRNewswire/ --
- flutiform k-haler achieved high levels of lung deposition of over 44% of delivered
- Plume force of flutiform k-haler was compared with fluticasone propionate/salmeterol
xinafoate delivered via the Seretide(R) Evohaler(R) pMDI and Sirdupla(R) pMDI devices
- Pharmacokinetic studies show efficacy and safety profile of new flutiform k-haler
device would be comparable to flutiform pMDI device
Mundipharma today announced new data from four studies demonstrating efficient drug delivery characteristics with flutiform(R) k-haler(R), a novel, breath-triggered inhaler, currently in development.
The efficacy of inhaled asthma treatments is dependent on adequate deposition of the drug in the lungs. Poor or improper inhaler technique in asthma patients can lead to critical inhaler errors and is associated with reduced disease control,, worse asthma outcomes and an increase in hospital visits, compared to patients with good inhaler technique.
The flutiform k-haler takes its name from a unique kinked valve which removes the need for co-ordination, with only gentle inhalation required to trigger the aerosol.
Details of the four flutiform k-haler presentations
The first study examined the pulmonary deposition of the flutiform k-haler device (125/5 microgram) using gamma scintigraphy and showed that in patients with asthma, high levels of lung deposition of over 44% of the delivered dose were achieved.
A second in vitro study compared the plume force of flutiform k-haler 125/5microg with fluticasone propionate/salmeterol xinafoate 125/25microg (FP/SAL) from the Seretide(R) Evohaler(R) pMDI; and 125/25microg FP/SAL from the Sirdupla(R) pMDI over distances of 25-95mm. 60-95mm represents the typical distance between the inhaler and back of the throat.  Plume characteristics of aerosol devices may affect drug delivery to the lungs and impaction at the back of the throat.
The final two single dose, cross-over pharmacokinetic studies assessed how pulmonary bioavailability and systemic exposure of fluticasone propionate and formoterol 125/5microg of flutiform k-haler compared to Mundipharma's existing flutiform pMDI device when administered in healthy adults with or without a spacer. These data suggest that the efficacy (based on pulmonary bioavailability) and safety (based on total systemic exposure) profile of the new device would be comparable to the registered flutiform pMDI device.  ,
Jonathan Marshall, Head of Medical Insights, Mundipharma International Limited commented: "The studies presented at this year's ERS conference demonstrate how effective the k-haler is at delivering fluticasone propionate/formoterol to the lungs, achieving high levels of lung deposition in patients with asthma. If approved, flutiform k-haler would offer a new device choice for certain patients with asthma."

About flutiform pMDI
In Europe, flutiform pMDI is licensed for the regular treatment of asthma when use of a combination product (an inhaled corticosteroid [ICS] and a long-acting beta2-agonist [LABA]) is appropriate: for patients not adequately controlled with an ICS and an 'as required' inhaled short-acting beta2-agonist or for patients already adequately controlled on both an ICS and a LABA. It is available in countries across Europe including the UK, Germany, France, Spain, Netherlands and Italy. flutiform pMDI is available in 50/5mug and 125/5mug strengths for adults and adolescents; 250/10mug strength for adults only.
Asthma is a chronic inflammatory disorder of the airways which leads to recurrent episodes of wheezing, breathlessness, chest tightness and coughing. Patients with poorly managed asthma are at an increased risk of exacerbations, hospitalisation and death. Poorly managed asthma can also have a huge impact on a person's quality of life and day-to-day activities.
About Gamma Scintigraphy
Gamma scintigraphy is an imaging technique using radioisotopes attached to drugs that travel to a specific organ or tissue and the emitted gamma radiation is captured by external detectors. This enables the direct visualisation and quantification of events occurring in vivo, in real time.
Vectura, a FTSE250 company listed on the London Stock Exchange , is an industry-leading device and formulation business for inhaled airways products offering a uniquely integrated inhaled drug delivery platform. With its extensive range of device and formulation technologies, integrated capabilities and collaborations, Vectura is a leader in the development of inhalation products, increasing its ability to help patients suffering from respiratory diseases.
Vectura has eight inhaled, four non-inhaled and ten oral products marketed by partners with growing global royalty streams. The group has a diverse portfolio of drugs in clinical development, including a number of novel and generic programmes which are partnered with several global pharmaceutical and biotechnology companies including Hikma, Novartis, Sandoz, Mundipharma, Kyorin, Baxter, GSK, UCB, Ablynx, Grifols, Bayer, Chiesi, Almirall, Janssen, Dynavax and Tianjin KingYork along with two wholly owned nebulised development programmes.
