Detailní popis

This was a phase III, multinational, multicentre, randomised, double-blind, double-dummy, active-control, 2-arm parallel group study designed to evaluate the non-inferiority of Foster® NEXThaler® 100/6 µg (400/24 µg/day) versus Foster® pMDI 100/6 µg (400/24 µg/day) in patients with controlled asthma.

The study included the following phases:

  • Pre-Screening Phase (Visit 0): Conducted within a maximum of 7 days before the screening visit (Visit 1), this phase provided patients with study details, obtained informed consent, and outlined medication restrictions.
  • Screening and Run-in Phase (Visit 1, Week -4 to Visit 2, Week -2): Patients underwent eligibility assessments and transitioned into a 4-week open-label run-in period with Foster® pMDI 100/6 µg (400/24 µg/day) to establish baseline parameters.
  • Randomisation Phase (Visit 3, Week 0): Eligible patients were randomised in a 1:1 ratio to receive either Foster® NEXThaler® 100/6 µg 2 inhalations bid (for a total daily dose of 400/24 µg/day) or Foster® pMDI 100/6 µg, 2 puffs bid (for a total daily dose of 400/24 µg/day) for 12 weeks. The allocation was managed via an Interactive Web Response System (IWRS) to ensure balanced treatment groups.
  • Investigational Phase (Treatment Period: Weeks 0-12): Patients attended scheduled visits at Weeks 2, 4, 6, 8, 10, and 12 to monitor efficacy and safety.

Daily, patients recorded pre-dose morning and evening Peak Expiratory Flow (PEF), rescue medication use, and asthma symptoms using an electronic peak flow meter and e-diary. At each visit, lung function (FEV1, FVC, and PEF), asthma symptom scores, and rescue medication use were assessed. Vital signs (heart rate, blood pressure) and safety outcomes (adverse events, serious adverse events, and laboratory assessments) were monitored.

  • Follow-Up Phase: A safety follow-up phone call was conducted 7-10 days after the final visit (Week 12) or early termination to assess any unresolved adverse events (AEs) or new concomitant medications.

The total study duration per participant was 16 weeks, including the 4-week run-in period, 12-week treatment phase, and 1-week follow-up. This design ensured a standardized baseline before randomisation and provided sufficient time to assess both primary and secondary endpoints.

Salbutamol (purchased locally and provided by the Investigator site to the patient) was used as a rescue medication.

Change From Baseline to End of Treatment Period in Average Pre-dose Morning Peak Expiratory Flow (PEF)
Časové okno: Baseline (Week 0, Visit 3) and Week 12 (EoT)

PEF= peak expiratory flow. The peak expiratory flow (also known as a peak flow or peak flow rate) is the maximal rate that a person can exhale during a short maximal expiratory effort after a full inspiration.

In this study PEF (L/min) was monitored twice daily using a portable electronic peak flow meter before medication intake: morning (7:00-9:00 am) and evening (7:00-9:00 pm). Each session required at least two blows, with the highest valid value recorded.

  • Baseline pre-dose morning PEF was calculated as the mean of all valid pre-dose morning Best PEF values from the last 14 days before randomization (Week 0, Visit 3).
  • The average pre-dose morning PEF over the entire treatment period was computed as:

    ∑Valid pre-dose morning Best PEF values (treatment period) / Number of days with available data

  • Valid pre-dose morning Best PEF values = Highest value recorded from at least two PEF measurements per session, within the range 50-900 L/min

  • Baseline percentage of symptom-free days was the mean percentage over the last 14 days before randomization (Week 0, Visit 3).
  • Percentage of asthma symptom-free days was calculated as:

(Number of symptom-free days / Total number of days with available data)×100

  • It was assessed for each inter-visit period (from the evening of the clinic visit to the morning of the next visit) and over the 12-week treatment period (from the evening of treatment start to the morning of treatment end).
  • At least 7 valid days were required per period, with at least one evaluable inter-visit period needed for full analysis.

An asthma control day was defined as a day without rescue medication use and with both total morning and total evening asthma symptom scores = 0. Only days with both scores available were included in the calculation.

  • Baseline percentage of asthma control days was the mean percentage over the last 14 days before randomization (Week 0, Visit 3).
  • Percentage of asthma control days was calculated as:

(Number of asthma control days / Total number of days with available data)×100

  • It was assessed for each inter-visit period (from the evening of the clinic visit to the morning of the next visit) and over the 12-week treatment period (from the evening of treatment start to the morning of treatment end).

Change From Baseline in Pre-Dose Morning FEV1 at Each Clinic Visit

Forced Expiratory Volume in 1 second (FEV1) was measured pre-dose in the morning (7:00-9:00 am) at each clinic visit using spirometry, following standardized procedures. Baseline FEV1 was recorded at Visit 3 (Week 0, randomization), and changes were assessed at each visit (Weeks 2, 4, 6, 8, 10, and 12).

Patients performed spirometry in a seated position, using the same calibrated spirometer across all visits. They inhaled deeply to total lung capacity and exhaled forcefully and completely. At least three acceptable maneuvers were required, with the highest valid measurement recorded. FEV1 was expressed in liters (L), and a higher value indicated better lung function.

Forced vital capacity (FVC) is the maximum capacity of air that a patient can exhale after a maximum inspiration. It measures the volume of air exhaled in a spirometer, after a maximal inspiration. FVC was measured pre-dose in the morning (7:00-9:00 am) at each clinic visit using spirometry, following standardized procedures. Baseline FVC was recorded at Visit 3 (Week 0, randomization), and changes were assessed at each visit (Weeks 2, 4, 6, 8, 10, and 12).

Patients performed spirometry in a seated position, ensuring consistency across visits. They were instructed to inhale deeply to full lung capacity and exhale forcefully and completely into the spirometer. At least three acceptable maneuvers were required per session, with the highest valid measurement recorded. The higher the capacity, measured in liters, the better the outcome.

Change From Baseline to Last Visit in ACQ-6 Score
Časové okno: Week 12 (Visit 9, End of Treatment - EOT)

The ACQ-6 was a validated questionnaire assessing asthma control, consisting of six items: five on asthma symptoms (nighttime waking, symptoms on waking, activity limitation, shortness of breath, wheezing) and one on rescue medication use, all self-administered. Each item was scored from 0 (no impairment) to 6 (maximum impairment), and the ACQ-6 total score was the mean of all six items, ranging from 0 (totally controlled asthma) to 6 (severely uncontrolled asthma). Hence, the higher the score, the worse the outcome.

Baseline ACQ-6 was assessed at Visit 3 (Week 0, randomization), and the final score was recorded at Visit 9 (Week 12, EOT). The change from baseline was calculated as the difference between these values .

Number of Participants With at Least One Adverse Event (TEAE) or Adverse Drug Reaction (ADR)
Časové okno: From Week 0 (Visit 3, Randomization) to Week 12 (Visit 9, EoT)

An adverse event (AE) was defined as "any untoward medical occurrence in a patient or clinical study patient administered a medicinal product and which did not necessarily have a causal relationship with this treatment". An AE could therefore be any unfavourable and unintended sign (including abnormal laboratory finding), symptom or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

An adverse drug reaction (ADR) was defined as an "untoward and unintended response to an investigational medicinal product related to any dose administered".

An SAE/serious ADR was defined as any untoward medical occurrence or effect that at any dose Resulted in death, Was life-threatening, Required hospitalisation or prolongation of existing hospitalisation, Resulted in persistent or significant disability or incapacity, Was a congenital anomaly or birth defect, Was a medically significant AE.
