Particle co-associations between the active pharmaceutical ingredients fluticasone propionate and salmeterol xinafoate were examined in dry powder inhaled (DPI) and metered dose inhaled (MDI) combination products. Single Particle Aerosol Mass Spectrometry was used to investigate the particle interactions in Advair Diskus(®) (500/50 mcg) and Seretide(®) (125/25 mcg). A simple rules tree was used to identify each compound, either alone or co-associated at the level of the individual particle, using unique marker peaks in the mass spectra for the identification of each drug...

RATIONALE: OT329 SOLIS is a generic candidate for the branded asthma treatment, ADVAIR DISKUS (fluticasone propionate/salmeterol xinafoate), and, as such, the manufacturer is required to provide evidence of clinical "bioequivalence" as a condition for regulatory approval. OBJECTIVES: The objective of the current study was to determine if SOLIS and DISKUS provided bioequivalent improvements in lung function at two time points: Day 1 and Week 4. METHODS: This study was a randomized, multiple-dose, placebo-controlled, parallel-group design conducted in the United States (NCT02260492) with a 2-week run-in followed by a 4-week treatment period...

We previously demonstrated pharmacokinetic differences among manufacturing batches of a US Food and Drug Administration (FDA)-approved dry powder inhalation product (Advair Diskus 100/50) large enough to establish between-batch bio-inequivalence. Here, we provide independent confirmation of pharmacokinetic bio-inequivalence among Advair Diskus 100/50 batches, and quantify residual and between-batch variance component magnitudes. These variance estimates are used to consider the type I error rate of the FDA's current two-way crossover design recommendation...

RANDOMIZED CONTROLLED TRIAL
E Burmeister Getz, K J Carroll, B Jones, L Z Benet
Current pharmacokinetic (PK) bioequivalence guidelines do not account for batch-to-batch variability in study design or analysis. Here we evaluate the magnitude of batch-to-batch PK variability for Advair Diskus 100/50. Single doses of fluticasone propionate and salmeterol combinations were administered by oral inhalation to healthy subjects in a randomized clinical crossover study comparing three different batches purchased from the market, with one batch replicated across two treatment periods. All pairwise comparisons between different batches failed the PK bioequivalence statistical test, demonstrating substantial PK differences between batches that were large enough to demonstrate bio-inequivalence in some cases...

INTRODUCTION: Phase III/IV clinical trials are expensive and time consuming and often suffer from poor enrollment and retention rates. Pediatric trials are particularly difficult because scheduling around the parent, participant and potentially other sibling schedules can be burdensome. We are evaluating using the internet and mobile devices to conduct the consent process and study visits in a streamlined pediatric asthma trial. Our hypothesis is that these study processes will be non-inferior and will be less expensive compared to a traditional pediatric asthma trial...

BACKGROUND AND OBJECTIVE: Inhaled corticosteroid (ICS)/long-acting beta(2)-agonist (LABA) combinations are the preferred maintenance therapy for adult asthma patients uncontrolled by ICS alone. Supporting data are largely from mixed populations of adolescents and adults, although ICS/LABA combinations are not approved for adolescents in all countries. This analysis evaluates overall asthma control in asthma patients aged >or=16 years receiving ICS/LABA combinations. METHODS: This was a post hoc analysis of asthma patients aged >or=16 years in a randomized, double-blind/open-label extension, parallel-group study...

The National Heart, Lung and Blood Institute guidelines for the treatment of asthma suggest that inhaled corticosteroids, with the addition of a long-acting bronchodilator, may be the most effective long-term control medication for asthma. Five inhaled corticosteroids are approved for use in the USA, including beclomethasone dipropionate, budesonide, flunisolide, triamcinolone acetonide and fluticasone propionate. Fluticasone propionate (Flixotide) and the long-acting beta2 agonist salmeterol (Serevent), are now available in the USA together in an easy to use dry powder inhaler Advair...

Salmeterol/fluticasone propionate (Seretide/Advair Diskus [dry powder inhaler] or Seretide/Advair inhalation aerosol [metered-dose inhaler]) is a fixed-dose combination inhalation agent containing a long-acting beta2-adrenoceptor agonist (LABA) plus a corticosteroid. In patients with symptomatic asthma, twice-daily salmeterol/fluticasone propionate maintenance therapy improves lung function and asthma symptoms to a greater extent than monotherapy with inhaled corticosteroids (ICS), such as fluticasone propionate, oral montelukast with or without fluticasone propionate, or sustained-release theophylline plus fluticasone propionate...

When an adequate standard of asthma control is not achieved with maintenance treatment of inhaled corticosteroids, the addition of a long-acting beta(2)-adrenergic receptor agonist (LABA) bronchodilator is recommended. Using a combination product, salmeterol/fluticasone propionate (Seretide or Advair) or budesonide/formoterol (Symbicort) is preferred for convenience and avoids any risk that LABA might be used as monotherapy. As formoterol has a rapid onset of bronchodilator effect, the budesonide/formoterol combination can be used for both the maintenance and reliever components of asthma treatment (Symbicort SMART) and this is endorsed as an effective treatment by the Global Initiative for Asthma...
