This is a comparative bioavailability study to compare the pharmacokinetics and
pharmacodynamic effects of Fluticasone propionate and Salmeterol delivered in a capsule-based
inhaler versus a multi-dose dry powder inhaler in patients with moderate asthma and in
patients with moderate to severe Chronic obstructive pulmonary disease (COPD).
Co-primary endpoints will be the area under the curve (AUCτ) measured for plasma Fluticasone
propionate (pharmacokinetic) and the pharmacodynamic effects of Fluticasone propionate
(weighted mean serum cortisol over 0-12h) on the last day of each 10 day study treatment
period. Secondary endpoints will include the following pharmacokinetic parameters for both
fluticasone propionate and salmeterol: AUClast, AUC(0-t), Cmax, Cmin, tmax, λz, and t1/2 as
well as the pharmacodynamic effects of salmeterol (pulse rate, blood pressure,
electrocardiogram [ECG], potassium and glucose) and Fluticasone propionate (urine cortisol
levels). Safety (adverse events and laboratory abnormalities) will also be assessed as a
secondary endpoint.
The study is a randomised, double blind, double dummy, four-period cross-over study.
Approximately 60 asthma or COPD patients will be randomised. Patients meeting eligibility
criteria will receive Fluticasone propionate/salmeterol 250/50mcg bid, from a capsule-based
inhaler and from a multi-dose dry powder inhaler for a period of 10 days each in a randomised
order. All patients will receive treatment from each device twice. To maintain the double
blind, each patient will receive active treatment and placebo at the same time from two
separate devices.

---|---|---|---|---|
Primary | Mean Area Under the Concentration Time Curve Over the Dosing Period (AUC[0-tau]) for FP | Blood samples of participants (par.) with asthma and chronic obstructive pulmonary disease (COPD) were collected and analyzed for AUC(0-tau), a measure of the amount of drug available at target tissue (in plasma) for a fixed dosing interval (12 hours). Asthma is a disorder that causes the airways of the lungs to swell and narrow, leading to difficulty in breathing. COPD is a chronic lung disease with structural changes in lungs, leading to difficulty in breathing. | At pre-morning dose; 5, 10, 30 minutes post-dose (PD); and 1, 2, 4, 8, 10, and 12 hours PD on Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Primary | Weighted Mean Serum Cortisol (SC) Over 0 to 12 Hours Post Dose | Participants' blood samples were collected and analyzed for SC levels. Weighted mean SC levels are evaluted as a measure of the degree of cortisol suppression, allowing for the determination of whether differences in systemic exposure to the inhaled steroid component of two devices can be significant enough to result in the differences in the body's ability to release cortisol. Weighted means were derived by calculating the AUC over the 0-12 hour period, using the linear trapezoidal rule (statistical technique used for numerical analysis) and then dividing it by the actual time interval. | At pre-morning dose; 30 minutes post-dose (PD); and 1, 2, 4, 8, 10, and 12 hours PD on Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean Plasma AUC(0-tau) and Plasma AUC From Time Zero (Pre-dose) to Last Time of Quantifiable Concentration (AUC[0-tlast]) for Salmeterol | Blood samples of participants with asthma and COPD were collected and analyzed for AUC(0-tau) and AUC(0-tlast). AUC(0-tau) is a measure of the amount of drug available at target tissue (in plasma) for a fixed dosing interval (12 hours). AUC(0-tlast) is a measure of the plasma drug concentration from pre-dose to the last measurable concentration. | At pre-morning dose; 5, 10, 30 minutes post-dose (PD); and 1, 2, 4, 8, 10, and 12 hours PD on Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean AUC(0-tlast) for FP | Blood samples of participants with asthma and COPD were collected and analyzed for AUC(0-tlast). AUC(0-tlast) is a measure of the plasma drug concentration from pre-dose to the last measurable concentration. | At pre-morning dose; 5, 10, 30 minutes post-dose (PD); and 1, 2, 4, 8, 10, and 12 hours PD on Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean Maximum Observed Concentration (Cmax) and Minimum Observed Concentration (Cmin) of FP | Blood samples of participants with asthma and COPD were collected and analyzed for Cmax and Cmin of FP in the blood. Cmax and Cmin are used to estimate the time at which the activity of the drug will be at its maximum and minimum, respectively. | At pre-morning dose; 5, 10, 30 minutes post-dose (PD); and 1, 2, 4, 8, 10, and 12 hours PD on Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean Terminal Phase Half-life (t1/2) for FP | Blood samples of participants were collected for evaluating t1/2. The t1/2 is the time required for the plasma/blood concentration of the drug to decrease by 50% after the false equilibrium of distribution has been reached. | At pre-morning dose; 5, 10, 30 minutes post-dose (PD); and 1, 2, 4, 8, 10, and 12 hours PD on Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |

Secondary | Mean Urine Cortisol Excretion Over 0 to 24 Hours Post Dose for FP | Urine samples of participants were collected to evaluate urine cortisol excretion over 0-24 hours post treatment dose. A 24-hour urine cortisol sample was used to measure the total amount of cortisol excreted in urine in 24 hours. Any differences in systemic exposure as a result of the absorbed steroid component of the two differing inhaled devices should also result in differences in the amount of cortisol excreted in the urine. | 0-24 hours post dose on Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Serum Cortisol Minimum (Cmin) for FP | Blood samples of participants were collected for the evaluation of minimum serum cortisol.

Secondary | Weighted Mean Over 0 to 4 Hours Post Dose of Heart Rate for Salmeterol | The heart rate (number of heartbeats per unit of time, typically expressed as beats per minute [bpm]) of the participants was monitored for evaluating the weighted mean over the course of 0 to 4 hours post dose. The Capsule-MDPI difference for heart rate was calculated for each participant, and the weighted mean value from the time of the morning dose on Day 10 to 4 hours post dose was calculated. The weighted mean was calculated by using all values at the indicated timepoint contributing to the calculation of the mean but with different weightage. | At pre-morning dose; 15, 30, 60, 90 minutes post-dose (PD); and 2, 4, 8, 10, and 12 hours PD on Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean of Maximum Heart Rate Over 0 to 4 Hours Post Dose for Salmeterol | The maximum observed value of heart rate was measured from the time of the morning dose on Day 10 to 4 hours post dose. | At pre-morning dose; 15, 30, 60, 90 minutes post-dose (PD); and 2, 4, 8, 10, and 12 hours PD on Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |

The maximum and minimum observed values from the time of the morning dose on Day 10 to 4 hours post dose were measured for SBP and DBP. The weighted mean value from the time of the morning dose on Day 10 to 4 hours post dose was calculated. Weighted mean was calculated by using all values of DBP and SBP at the indicated timepoint contributing to the calculation of the mean but with different weightage. | At pre-morning dose; 15, 30, 60, 90 minutes post-dose (PD); and 2, 4, 8, 10, and 12 hours PD on Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Maximum and Weighted Mean Over 0 to 4 Hours Post Dose of the QT Interval Corrected According to Bazett's Formula (QTc[B]) and the QT Interval Corrected According to Fridericia's Formula (QTc[F]) | The electrocardiogram (ECG) of the participants was taken, and the maximum and weighted mean of QTc(B) and QTc(F) was measured. Weighted mean was calculated by using all values of QTc(B) and QTc(F) at the indicated timepoint contributing to the calculation of the mean but with different weightage. The ECG helps in the assessment of the condition of the heart. The QT interval gives the measure of the heart rate, and the cQT interval gives the corrected value. | At pre-morning dose; 15, 30, 60, 90 minutes post-dose (PD); and 2, 3 and 4 hours PD on Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |

Secondary | Mean Hemoglobin and Mean Corpuscular Hemoglobin (MCH) Concentration | Blood samples of participants were collected for the evaluation of mean hemoglobin (mean level of hemoglobin in the whole blood sample) and MCH concentration. The MCH concentration is the average concentration of hemoglobin in a red blood cell. Hemoglobin is the red pigment in the blood, and it is reponsible for carrying oxygen. The timing of the first and second administrations depended on the randomization schedule. If the treatment sequence received was "ABBA," then Days 10 and 40, respectively, correspond to the first and second administrations for treatment A. | Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Red Blood Cell (RBC) Count and Reticulocytes | Blood samples of participants were collected for the evaluation of RBC and reticulocytes count. Reticulocytes are immature red blood cells. Normally, about 1% to 2% of the red blood cells in the blood are reticulocytes. The timing of the first and second administrations depended on the randomization schedule. If the treatment sequence received was "ABBA," then Days 10 and 40, respectively, correspond to the first and second administrations for treatment A. | Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean Corpuscule Hemoglobin (MCH) | Blood samples of participants were collected for the evaluation of MCH. MCH is the average mass or amount of hemoglobin per red blood cell in a sample of blood. The timing of the first and second administrations depended on the randomization schedule. If the treatment sequence received was "ABBA," then Days 10 and 40, respectively, correspond to the first and second administrations for treatment A. | Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean Corpuscle Volume (MCV) | Blood samples of participants were collected for the evaluation of MCV. MCV is a measure of the average red blood cell size that is reported as part of a standard complete blood count. The timing of the first and second administrations depended on the randomization schedule. If the treatment sequence received was "ABBA," then Days 10 and 40, respectively, correspond to the first and second administrations for treatment A. | Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean Hematocrit | Blood samples of participants were collected for the evaluation of hematocrit. The hematocrit is the percentage of the RBCs in the blood. The timing of the first and second administrations depended on the randomization schedule. If the treatment sequence received was "ABBA," then Days 10 and 40, respectively, correspond to the first and second administrations for treatment A. | Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean Albumin and Total Protein | The timing of the first and second administrations depended on the randomization schedule. If the treatment sequence received was "ABBA," then Days 10 and 40, respectively, correspond to the first and second administrations for treatment A. | Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean Alkaline Phosphatase (AP), Alanine Amino Transferase (ALT), Aspartate Amio Transferase (AST), and Gama Glutamyl Transferase (GGT) | Blood samples of participants were collected for the evaluation of AP, ALT, AST, and GGT. All of these parameters are measured to help assess the condition of the liver. The timing of the first and second administrations depended on the randomization schedule. If the treatment sequence received was "ABBA," then Days 10 and 40, respectively, correspond to the first and second administrations for treatment A. | Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean Direct Bilirubin (DB), Total Bilirubin (TB), Creatinine, and Uric Acid | Blood samples of participants were collected for the evaluation of DP, TB, creatinine, and uric acid. DB and TB are measures that help assess the condition of the liver, and creatinine and uric acid are measures that help assess the condition of the kidneys. The timing of the first and second administrations depended on the randomization schedule. If the treatment sequence received was "ABBA," then Days 10 and 40, respectively, correspond to the first and second administrations for treatment A. | Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Mean Calcium, Chloride, Glucose, Potassium, Sodium, Carbon Dioxide (CO2) Content/Bicarbonate (Bicar), and Urea/Blood Urea Nitrogen (BUN) | Blood samples of participants were collected for the evaluation of calcium, chloride, glucose, potassium, sodium, carbon dioxide (CO2) content/bicarbonate, and urea/BUN. All of these parameters are measured to help assess the condition of the kidneys. The timing of the first and second administrations depended on the randomization schedule. If the treatment sequence received was "ABBA," then Days 10 and 40, respectively, correspond to the first and second administrations for treatment A. | Day 10 of each study period (P): Study Day (SD) 10 (reference day is SD 1 or Randomization day), 20, 30, and 40 (+/-1) for P 1, 2, 3, and 4, respectively | |
Secondary | Number of Participants With an Adverse Event (AE) | An AE is defined as any untoward medical occurrence in a patient or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. | Randomization (Day 1) up to Follow-up (Days 47-50) |
