Comparison Between CHF5993 pMDI 200/6/12.5 µg HFA-152a VS CHF5993 pMDI 200/6/12.5 µg HFA-134a in Subjects With Asthma (TRECOS). (TRECOS)

April 9, 2026 updated by: Chiesi Farmaceutici S.p.A.

A 12-week Double-blind, Multicentre, Randomised, Active-controlled, 2-arm, Parallel-group Clinical Trial to Evaluate the Safety of CHF5993 pMDI 200/6/12.5 μg HFA-152a, Compared to CHF5993 pMDI 200/6/12.5 μg HFA-134a, in Subjects With Asthma.

The CLI-05993AB6-03 Study is an interventional study designed to investigate the safety and efficacy of a new low global warming potential propellant (HFA-152a) compared to the currently approved one (HFA-134a) in the medication (CHF5993) in patients with moderate to severe asthma

Description

Inclusion Criteria:

  • Subject's written informed consent obtained prior to any study related procedure;
  • Male and female adults aged ≥ 18 and ≤ 75;
  • Body mass index (BMI) within the range of 18.0 to 35.0 kg/m2 inclusive;

  • Diagnosis of asthma: physician-diagnosed asthma for at least
  • 6 months and with diagnosis before the age of 50 years;

  • Subjects must have a cooperative attitude and the ability to be trained to use correctly the pMDI inhalers and e-Diary, to be able to read/write, to be able to perform the required outcomes measurements (e.g., technically acceptable spirometry, e-Diary completion) and the ability to understand the risks involved.

Exclusion Criteria:

  • History of near fatal asthma, hospitalisation for asthma in intensive care unit which in the judgement of the Investigator may place the subject at undue risk, emergency room access for asthma in the previous 6 months before enrolment;
  • Asthma exacerbation requiring systemic corticosteroids (SCS) or emergency room admission or hospitalisation within 4 weeks prior to study entry and/or during the run-in period (to be checked again prior to randomisation);
  • Non-permanent asthma: exercise-induced, seasonal asthma (as the only asthma-related diagnosis) not requiring daily asthma control medecine

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Relative change from pre-dose Forced Expiratory Volume in one second with (FEV1) (Safety Assessment to evaluate of the potential bronchoconstriction of the study treatment)
Time Frame: Day 1
Relative change from pre-dose in FEV1 at the 10 min post-dose timepoint
Day 1

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To complete the evaluation of FEV1 and the potential for bronchoconstriction of the study treatment (relative change from pre-dose FEV1)
Time Frame: Day 1, Day 7, Week 4, Week 12
Relative change from pre-dose in FEV1 at all the post dose timepoints
Day 1, Day 7, Week 4, Week 12
To complete the evaluation of FEV1 and the potential for bronchoconstriction of the study treatment (absolute change from pre-dose FEV1)
Time Frame: Day 1, Day 7, Week 4, Week 12
Absolute change from pre-dose in FEV1 at all post-dose timepoints
Day 1, Day 7, Week 4, Week 12
To complete the evaluation of FEV1 and the potential for bronchoconstriction of the study treatment (number and percentage of subjects with a relative decrease from pre-dose in FEV1)
Time Frame: Day 1, Day 7, Week 4, Week 12
Calculation of number and percentage of subjects with a relative decrease from pre-dose in FEV1 at each post-dose timpoint and at any post -dose timepoint > 15%
Day 1, Day 7, Week 4, Week 12
To complete the evaluation of FEV1 and the potential for bronchoconstriction of the study treatment (Absolute and relative changes from baseline in pre-dose FEV1)
Time Frame: Day 1, Day 7, Week 4, Week 12
Absolute and relative changes from baseline in pre-dose FEV1 at all clinical visits
Day 1, Day 7, Week 4, Week 12
To complete the evaluation of FEV1 and the potential for bronchoconstriction of the study treatment (Change from pre-dose in FEV1)
Time Frame: Day 1, Day 7, Week 12
Change from pre-dose in FEV1 AUC 0-2h
Day 1, Day 7, Week 12
Peak expiratory flow (PEF) change from baseline at each inter-visit period over the entire treatment period
Time Frame: Inter-visit, over the entire 12 weeks treatment period
Change from baseline at each inter-visit period and over the entire treatment period in morning and evening PEF
Inter-visit, over the entire 12 weeks treatment period
Percentage of days without intake of rescue medication.
Time Frame: Inter-visit, over the entire 12 weeks treatment period
Change from baseline at each inter-visit period and over the entire treatment period in the percentage of days without intake of rescue medications
Inter-visit, over the entire 12 weeks treatment period
Change in the average daily use of rescue medication.
Time Frame: Inter-visit, over the entire 12 weeks treatment period

Inter-visit, over the entire 12 weeks treatment period
Change on the average daily asthma symptoms.
Time Frame: Inter-visit, over the entire 12 weeks treatment period
Change from baseline at each inter-visit period and over the entire treatment period in the average daily symptoms. Patients are asked to complete daily a questionnaire to collect this information and allow their asthma symptoms to be monitored.
Inter-visit, over the entire 12 weeks treatment period
Change from baseline in Asthma Control Questionnaire 7 (ACQ 7) score.
Time Frame: At each planned on site study visit, during the entire 12 weeks treatment period.
ACQ 7 is a one week recall questionnaire including 6 questions to be completed by patients on a 7-points scale (0=no impairment, 6= maximum impairment) and 7th point capturing the FEV1 % predicted value (also scoring on a 7-point scale). Questions are equally weighted and the ACQ score is the mean of the 7 questions and therefore between 0 (totally controlled) and 6 (severely uncontrolled).
At each planned on site study visit, during the entire 12 weeks treatment period.
