About this study
Official title: A 26-Week Open-Label Study to Assess the Long-Term Safety of Fluticasone Propionate Multidose Dry Powder Inhaler and Fluticasone Propionate/Salmeterol Multidose Dry Powder Inhaler in Patients 12 Years of Age and Older With Persistent Asthma
The primary objective of the study is to evaluate the long-term safety of fluticasone propionate (Fp) inhalation powder in 2 strengths and fluticasone propionate/salmeterol inhalation (FS) powder in 2 strengths when administered with the Teva multidose dry powder inhaler (MDPI) device over 26 weeks in patients with persistent asthma.
Read the detailed description
This was a stratified, randomized, open-label, active drug-controlled Phase 3 study.
Patients who met all of the inclusion criteria and none of the exclusion criteria at the screening visit completed a 14 day (±2 days) pretreatment run in period. During the run-in period, patients continued using their current asthma medications (ie, inhaled corticosteroid and/or other controller therapies) except for their SABA, which was replaced by the sponsor-provided albuterol (salbutamol) hydrofluoroalkane (HFA) inhaler to be used as needed for symptomatic relief of asthma symptoms during the run in and treatment periods.
Patients were assigned to inhaled corticosteroid (ICS) monotherapy or inhaled corticosteroid/long acting beta2 agonist (ICS/LABA) combination therapy and then to a mid- or high-treatment strength based on their current asthma maintenance therapy regimen. Patients in each strength of the ICS monotherapy cohort were randomly assigned in a 3:1 distribution to either the Fp MDPI or FLOVENT HFA treatment arm. Patients in each strength of the ICS/LABA combination cohort were randomly assigned in a 3:1 distribution to either the FS MDPI or ADVAIR DISKUS treatment arm. There was a total of 8 treatment arms following randomization.

What is being measured
The primary outcome is the main question the study is designed to answer.
Participants With Treatment-Emergent Adverse Experiences (TEAE) During the Treatment Period
An adverse event was defined as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator on a scale of mild, moderate and severe, with severe= an AE which prevents normal daily activities. Relationship of AE to treatment was determined by the investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical intervention to prevent the previously listed serious outcomes.
Measured: Day 1 to Week 26 of the Treatment Period
Secondary outcomes (5)
Participants With Positive Swab Test Results for Oral Candidiasis
Oropharyngeal examinations for visual evidence of oral candidiasis were conducted at each visit by a qualified healthcare professional. Any visual evidence of oral candidiasis during the oropharyngeal exam was evaluated by obtaining and analyzing a swab of the suspect area.
This outcomes indicates how many participants had positive swab test results. The total number of participants who had oropharyngeal exams at each timepoint are specified in the timepoint field. Appropriate therapy was to be initiated immediately at the discretion of the investigator and was not to be delayed for culture confirmation. Participants with a culture-positive infection could continue participation in the study on appropriate anti-infective therapy, provided this therapy was not prohibited by the protocol.
Measured: Baseline (Day 1 pre-treatment), Weeks 2, 6, 10, 14, 18, 22 26, Endpoint
Participants With Potentially Clinically Significant Abnormal Vital Signs During the Treatment Period
Data represents participants with potentially clinically significant (PCS) vital sign values during the Treatment period.
Significance criteria:
- Systolic blood pressure - high: >=180 and increase >=20 mmHg
- Systolic blood pressure - low: <=90 and decrease >=20 mmHg
- Diastolic blood pressure - high: >=105 and increase of >=15 mmHg
- Diastolic blood pressure - low: <=50 and decrease of >=15 mmHg
- Pulse - high: >=120 and increase of >= 15 beats/minute from baseline
- Pulse - low: <=50 and decrease of >=15 beats/minute
Measured: Baseline (Day 1 pre-treatment), Weeks 2, 6, 10, 14, 18, 22 26, Endpoint
Shifts From Baseline to Endpoint in Electrocardiogram (ECG) Findings
A 12 lead ECG was conducted at the screening visit and week 26 or the early termination visit. A qualified physician at a central diagnostic center was responsible for interpreting the ECG. The worst post-baseline finding for the participant is summarized. Endpoint refers to the last observation carried forward.
Measured: Screening (Day -14), Endpoint (week 26 if study was completed)
Analysis of 24-Hour Urine Cortisol Free Over the 26-Week Treatment Period
Samples for 24-hour urine cortisol were collected at baseline (Day 1, pretreatment), and Weeks 14 and 26. For participants requiring early termination (ET), this evaluation was performed at the ET visit. For participants requiring ET for safety reasons, the visit was not delayed in order to collect the 24-hour urine cortisol.
The analysis is based on a mixed model for repeated measures (MMRM) model with adjustment for visit, treatment, and a treatment*visit interaction. The urine cortisol result is log transformed prior to analysis and the results are back transformed after modeling. An unstructured covariance matrix is used in the MMRM model.
Measured: Baseline (Day 1, pre-treatment), Weeks 14 and 26 and early termination visit if applicable
Change From Baseline in Trough Forced Expiratory Volume in 1 Minute (FEV1) Over the 26-Week Treatment Period
Spirometry measurements were obtained before the AM dose of study drug for the randomization visit (Day 1), at each of the treatment visits and at the early termination visit if applicable. At each visit where FEV1 was assessed, the highest acceptable results from each session were recorded.
The analysis is based on a mixed model for repeated measures (MMRM) with adjustment for baseline FEV1, sex, age, (pooled) investigational center, visit, treatment, and treatment-by-visit. An unstructured covariance matrix is used in the MMRM model.
Measured: Baseline (Day 1 pre-treatment), Weeks 2, 6, 10, 14, 18, 22 26, early termination visit if applicable

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The primary objective of the study is to evaluate the long-term safety of fluticasone propionate (Fp) inhalation powder in 2 strengths and fluticasone propionate/salmeterol inhalation (FS) powder in 2 strengths when administered with the Teva multidose dry powder inhaler (MDPI) device over 26 weeks in patients with persistent asthma.
Detailed description
This was a stratified, randomized, open-label, active drug-controlled Phase 3 study.
Patients who met all of the inclusion criteria and none of the exclusion criteria at the screening visit completed a 14 day (±2 days) pretreatment run in period. During the run-in period, patients continued using their current asthma medications (ie, inhaled corticosteroid and/or other controller therapies) except for their SABA, which was replaced by the sponsor-provided albuterol (salbutamol) hydrofluoroalkane (HFA) inhaler to be used as needed for symptomatic relief of asthma symptoms during the run in and treatment periods.
Patients were assigned to inhaled corticosteroid (ICS) monotherapy or inhaled corticosteroid/long acting beta2 agonist (ICS/LABA) combination therapy and then to a mid- or high-treatment strength based on their current asthma maintenance therapy regimen. Patients in each strength of the ICS monotherapy cohort were randomly assigned in a 3:1 distribution to either the Fp MDPI or FLOVENT HFA treatment arm. Patients in each strength of the ICS/LABA combination cohort were randomly assigned in a 3:1 distribution to either the FS MDPI or ADVAIR DISKUS treatment arm. There was a total of 8 treatment arms following randomization.

Primary outcome
Participants With Treatment-Emergent Adverse Experiences (TEAE) During the Treatment Period
Time frame: Day 1 to Week 26 of the Treatment Period
An adverse event was defined as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator on a scale of mild, moderate and severe, with severe= an AE which prevents normal daily activities. Relationship of AE to treatment was determined by the investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical intervention to prevent the previously listed serious outcomes.
