About this study

This is a Phase 2, Single Arm, Open Label Extension Study, Evaluating the Long-Term Safety and Clinical Efficacy of SAR447537 (INBRX-101) in Adults With Alpha-1 Antitrypsin Deficiency (AATD) Emphysema.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Males or females 18-80 years of age, inclusive, at the time of screening
  • Diagnosis of AATD
  • Evidence of emphysema secondary to AATD
  • FEV1 of ≥ 30% predicted at screening and post-bronchodilator FEV1/FVC<0.7
  • Current non-smoking status

Exclusion criteria

For newly identified participants

  • Receipt of A1PI augmentation therapy within 5 weeks prior to the first dose of study drug
  • Known or suspected allergy to components of SAR447537, A1PI or human IgG
  • Uncontrolled diabetes mellitus despite adequate antidiabetic pharmacologic treatment with a screening HbA1c value ≥9%
  • Received IV immunoglobulins, monoclonal antibodies and/or other biologic therapies within 30 days
  • On waiting list for lung or liver transplant
  • Acute respiratory tract infection or COPD exacerbation within 4 weeks prior to or during screening
  • Evidence of decompensated cirrhosis
  • Active cancers or has a history of malignancy within 5 years prior to screening
  • History of unstable cor pulmonale

The above information is not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.

Treatment and study plan

SAR447537

Drug

A1PI, Recombinant, Bivalent Fc Fusion Protein

Primary outcomes

  1. Long-term safety and tolerability

    Time frame: 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 outcomes

  1. Change in lung density by quantitative computerized tomography (CT)

    Time frame: 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).

  2. Trough SAR447537 concentration changes

    Time frame: 3 years

    Change in SAR447537 concentration levels from baseline to end of treatment

  3. Trough serum functional AAT (fAAT) concentration changes

    Time frame: 3 years

    Change in fAAT concentration levels from baseline to end of treatment

  4. Covariate Analysis: Biometric Values: Weight

    Time frame: 3 years

    Assessment of the impact of participant's weight [in kg] on the pharmacokinetic profile of SAR447537

  5. Covariate Analysis: Biometric Values: Height

    Time frame: 3 years

    Assessment of the impact of participant's height [in cm] on the pharmacokinetic profile of SAR447537

  6. Covariate Analysis: Biometric Values: Age

    Time frame: 3 years

    Assessment of the impact of participant's age [in years] on the pharmacokinetic profile of SAR447537

  7. Covariate Analysis: Biometric Values: Sex

    Time frame: 3 years

    Assessment of the impact of participant's sex [male or female] on the pharmacokinetic profile of SAR447537

  8. Anti-drug antibodies

    Time frame: 3 years

    Frequency of anti-drug antibodies (ADA) against SAR447537 as well as neutralizing ADA (NAb) against SAR447537
