A serum pregnancy test is required for females of childbearing potential at the initial screening visit (Visit 1) and Visit 11 or Early Withdrawal. In addition a urine pregnancy test will be performed on all females of childbearing potential at Visit 2, Visit 5 and Visit 12.
  • Severity of Disease: A best pre-bronchodilator FEV1 of >=80% of the predicted normal value at the screening visit (Visit 1). Predicted values will be based upon National Health and Nutrition Examination Survey (NHANES) III. As subjects are Asian, the Asian adjustment will be used.
  • Stable Asthma: Subjects must have stable asthma, as judged by the Investigator. This includes no change in asthma medication for at least 8 weeks prior to Visit 1 and an ACT score of >=20 at Visit 1.
  • Current Anti-Asthma Therapy: All subjects must be using the middle-dose ICS/LABA which is equivalent to twice-daily combination of fluticasone propionate and salmeterol 250 mcg for at least 12 weeks prior to the registration visit. In addition, the prescription of the middle-dose ICS/LABA shouldn't be changed at least 8 weeks prior to Visit 1.

About this study

Official title: 201135 : A Randomised, Double-blind, Multicenter, Parallel-group Study to Compare the Efficacy and Safety of Fluticasone Furoate (FF) 100 mcg Once Daily With Fluticasone Propionate (FP) 250 mcg Twice Daily (BD) and FP 100 mcg BD in Well-controlled Asthmatic Subjects Stepped Down From a Maintenance Therapy With RELVAR® Inhaler (FF/VI) 100/25 mcg Once-daily in Japanese Subjects

The primary aim of this study is to clarify the position of FF and FF/Vilanterol (VI) 100/25 micrograms (mcg) compared with existing therapies by assessing FF dosage equivalent to low to middle-dose inhaled corticosteroids (ICS). The study is divided into Run-in period, Period 1 (open-label treatment), Period 2 (double blind treatment) and Follow-up. Subjects with well controlled asthma after completing a run-in period of 4 weeks will be switched from middle-dose ICS/long acting beta 2 agonist (LABA) equivalent dose to once-daily FF/VI 100/25 mcg for an 8 weeks treatment period (Period 1). After this, subjects will be randomized in a 1:1:1 ratio to receive either FP 250 mcg twice daily, FP 100 mcg twice daily or FF 100 mcg once daily in a 12 week double blind treatment period (Period 2). There will be a 1 week Follow-up Period following completion of the double-blind treatment period, or early withdrawal from the study. Overall , the total duration of subject's participation in the study will be for 25 weeks. RELVAR is a registered trademark of the GSK group of companies.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants (Par) Withdrawn From the Study Due to "Poorly-controlled Asthma" During Period 2

    Asthma symptom scores (SS) were recorded by par using ratings 0 (no symptoms) to 5-symptoms so severe that par could not perform normal activity [morning] or to 4-symptoms so severe that par could not sleep at all [nightly]. Withdrawal due to poorly-controlled(WPC) (required step-up therapy) asthma was defined as asthma worsening/exacerbation or ≧3 per week of : day symptoms on ≧ 2 days, rescue use on ≧2 days, morning PEF <80 % of best effort on ≧ 1 day, night symptoms on ≧1 or more day, a best pre-bronchodilator forced expiratory volume in 1s (FEV1) < 80% at clinic . Percentage of par WPC asthma at visit 6, 7, 9 and 11 (Week 10, 12, 16 and 20 respectively) were reported. Cox Proportional Hazards Model was used with covariates of Baseline FEV1, gender, age and treatment group. Analysis was descriptive only, no p -values calculated, treatment differences and associated 95% CI were produced.

    Measured: From Week 9 to Week 20

  2. Percentage of Participants With 'Well-controlled Asthma' at the End of Period 2

    Asthma symptom scores(SS) were recorded by par using ratings 0 (no symptoms) to 5-symptoms so severe that par could not perform normal activity[morning] or to 4-symptoms so severe that par could not sleep at all[nightly]. "Well-controlled asthma" was defined as having no exacerbation/asthma worsening, no night-time symptoms, a best pre-bronchodilator forced expiratory volume in 1 second ≥80% at clinic, and ≥2 per week of: daytime symptoms on ≤1 day, rescue use on ≤1 day, or morning peak expiratory flow ≥80% of the best effort value. "Well-controlled asthma" at the end of period 2 was assessed in the week prior to Visit 11 (Week 20). Percentage of participants were calculated as the number of participants with "well-controlled asthma" divided by total number participants excluding withdrawals prior to visit 11 (end of period 2) other than asthma worsening/exacerbation. A Logistic Regression Model was used with covariates of Baseline FEV1, gender, age and treatment group.

    Measured: Week 20

Secondary outcomes (6)

  1. Least Squares Mean Change From Baseline in Clinic Visit Trough FEV1 at the End of Period 2

    FEV measures amount of air a person can exhale during a forced breath. The amount of air exhaled in one second of the forced breath is FEV1. Trough FEV1 was measured between 3pm and 11pm excluding Visit 1. Highest value from the three acceptable measurements were recorded. Change from Baseline was calculated as adjusted mean FEV1 value during Period 2 minus Baseline. The Baseline value was the predose value at the randomization (Visit 5: Week 8). Analysis of covariance (ANCOVA) Model was used with covariates of baseline FEV1, gender, age and treatment group. The adjusted mean from this model is presented [least square mean (LSM)].

    Measured: Week 20

  2. Least Squares Mean Change From Baseline in Daily Morning (AM) and Evening (PM) PEF Averaged During Period 2

    Peak expiratory flow is a person's maximum speed of expiration, as measured with a peak flow meter which determines person's ability to breathe out air. PEF was measured each morning and evening prior to study medication or any rescue salbutamol inhalation aerosol use, using an electronic peak flow meter. Mean change from Baseline was calculated as PEF value averaged during Period 2 (Week 9 to Week 20) minus Baseline. Data is presented separately for morning(AM) and evening(PM) assessments. The Baseline value was the mean of the daily values in one week prior to randomization (Visit 5: Week 8) separately for morning and evening. Adjusted mean change from baseline is presented [least square mean (LSM)].

    Measured: From Week 9 to Week 20

  3. Least Squares Mean Change From Baseline in the Percentage of Symptom Free 24 Hour Periods During Period 2

    Participants who were symptom free for 24-hours were assessed with the help of a daily Dairy. It included the details on daily asthma symptom scores ranging from 0 (no symptoms) to 5-symptoms so severe that participant could not perform normal activity [morning] or to 4-symptoms so severe that participants could not sleep at all [nightly]. Mean change from Baseline was calculated as percentage of symptom free 24 hours during Period 2 (Week 9 to Week 20) minus Baseline. The Baseline value was the mean of the daily values in one week prior to randomization (Visit 5: Week 8). Adjusted mean change from baseline is presented [least square mean (LSM)].

    Measured: From Week 9 to Week 20

  4. Least Squares Mean Change From Baseline in the Percentage of Rescue Free 24 Hour (hr) Periods During Period 2

    The time during which the participants did not have to take any rescue medication (medication intended to relieve symptoms immediately) was considered as a rescue free period. Participants who did not require inhalation of salbutamol (rescue medication) for 24-hours were captured with the help of a daily dairy, all participants were required to record use of rescue medication daily for day and night time separately on e-diary. Mean change from Baseline was calculated as percentage of rescue free 24 hour period during Period 2 (Week 9 to Week 20) minus Baseline value. The Baseline value was the mean of the daily values in one week prior to randomization (Visit 5: Week 8). Adjusted mean change from baseline is presented [least square mean (LSM)].

    Measured: From Week 9 to Week 20

  5. Least Squares Mean Change From Baseline in Asthma Control Test (ACT) Score at the End of Period 2

    The total ACT score is the sum of the scores attributed to the five questions, ranging from 5 (poor control of asthma) to 25 (complete control of asthma), with higher scores reflecting greater asthma control. An ACT score >=20 indicates well-controlled asthma. The questions were designed to be self-completed by the participant. Mean change from Baseline was calculated as ACT score at the end of Period 2 (Week 20) minus Baseline value. The Baseline value was the predose value at randomization (Visit 5: Week 8). Adjusted mean change from baseline is presented [least square mean(LSM)].

    Measured: Week 20

  6. Proportion of Subjects With ACT Score >= 20 at Visit 11 (Week 20)

    Asthma control test is a five item questionnaire with each response rating from 1 to 5 (1 is severe and 5 is no event) of asthma events over previous 4-weeks. The questions were designed to be self-completed by the participant. The percentage of participants with ACT score >=20 at the end of the Period 2 were analyzed using a logistic regression model including covariates for baseline ACT score, gender, age and treatment group.

    Measured: Week 20

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Jun 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants (Par) Withdrawn From the Study Due to "Poorly-controlled Asthma" During Period 2 (time frame: From Week 9 to Week 20). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02094937.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 May 2017.
