Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Long-term safety and tolerability | 3 years | Incidence of all treatment emergent adverse events (TEAEs), TEAEs ≥ Grade 3, serious adverse events (SAEs), TEAEs leading to discontinuation from SAR447537, and adverse events of special interest (AESIs) (including infusion-related reactions). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in lung density by quantitative computerized tomography (CT) | 3 years | Assess the annual rate of change in lung density assessed by serial quantitative CT (15th percentile point, PD15) at total lung capacity (TLC), centrally read, from baseline to end of treatment (EoT). |
| Trough SAR447537 concentration changes | 3 years | Change in SAR447537 concentration levels from baseline to end of treatment |
| Trough serum functional AAT (fAAT) concentration changes | 3 years | Change in fAAT concentration levels from baseline to end of treatment |
| Covariate Analysis: Biometric Values: Weight | 3 years | Assessment of the impact of participant's weight \[in kg\] on the pharmacokinetic profile of SAR447537 |
| Covariate Analysis: Biometric Values: Height | 3 years | Assessment of the impact of participant's height \[in cm\] on the pharmacokinetic profile of SAR447537 |
