Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the change in ventilation pattern complexity and variability after 1 month of treatment by BGF 160;Secondary Objective: 1.To assess the change in Oscillatory mechanics, Flows and Lung volumes one month after administration of BGF 160 2. To assess the association between clinical response on dyspnea (TDI at V3) and the changes of variability/PFT between V2 and V3 3. To compare dyspnea and symptoms before administration of BGF 160 (at V2 base (pre-treatment)) and after administration (at V3 peak (2 hours (+/-30min) at one month) 4.To compare the ventilation pattern variability and complexity at the other time points : -V2 baseline vs V2 peak (first dose effect) -V2 baseline vsV3 trough (residual effect) ;Primary end point(s): Analysis of tidal volume (VT) complexity (noise limit as main parameter ) : Comparison of the noise limit between V2 baseline (pre-treatment) and V3 peak (2 hours (+/-30min) post dose ) ;Timepoint(s) of evaluation of this end point: During patients visits | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Outcome Measure 1:Change between V2 base (pre-treatment) and V3 peak (2 hours (+/-30min) post dose) of : - Impulse oscillometry or forced oscillation: resistances at 5Hz, reactance at 5Hz - Spirometry: Changes in FEV1 - Plethysmographic Functional residual capacity (FRC) Outcome Measure 2:Changes between V2 base measurement (pre-treatment) and V3 peak (2 hours (+/-30min) measurement for noise limit, respiratory frequency, volume, largest Lyapounov component, resistances at 5Hz, reactance at 5Hz, FEV1and FRC versus TDI at V3 (in term of continuous variable and in term of binary variable “responder/non responder”; a response is defined by a change in TDI =+1 between baseline and V3) Outcome Measure 3: - dyspnea scores: - Baseline dyspnea index ( BDI) - Transition dyspnea index (TDI) - Modified dyspnea profile ( MDP) - CAT score - Likert scale for dyspnea and general health Outcome Measure 4:Noise limit, respiratory frequency, volume, largest Lyapounov compone, resistances at 5Hz, reactance at 5Hz, FEV1, FRC ,and VAS dyspnea/chest tightness ;Timepoint(s) of evaluation of this end point: During patients visits | — |
