About AATD and INBRX-101

Alpha-1 Antitrypsin Deficiency ("AATD") is an under-diagnosed genetic disease affecting an estimated 100,000 patients in the US. It is characterized by insufficient levels of AAT causing emphysema, loss of lung function, and decreased life expectancy. Based on biochemical efficacy, plasma-derived AAT ("pdAAT") therapy was approved in the 1980s and is administered weekly to maintain serum AAT concentrations above 11 µM, which is below the normal range. Since then, little progress has been made with new treatment modalities and cost/supply of pdAAT remains a challenge.

The INBRX-101 study is an open-label, international Phase 1 trial designed to assess safety, pharmacokinetics ("PK"), pharmacodynamics ("PD"), and immunogenicity (NCT03815396). AATD patients were administered single or multiple doses (three consecutive doses every three weeks) of 10, 40, 80 or 120 mg/kg INBRX-101 via IV infusion.

As of November 2021, 24 AATD patients have been administered INBRX-101 at doses of 10 mg/kg (n=6), 40 mg/kg (n=6), 80 mg/kg (n=6) and 120 mg/kg (n=6). INBRX-101 has been well tolerated without serious adverse reactions, dose-limiting toxicities, or severe treatment emergent adverse events. The most common drug related adverse events reported were fatigue (n=5), pruritus (n=5), blood pressure increased (n=5), urticaria (n=4), and infusion related reactions (n=2). Infusion related reactions (e.g., pruritus, blood pressure increased, urticaria, infusion related reactions) were transient, mostly mild (Grade 1 per CTCAEv5.0) except for one moderate event (Grade 2) and responded well to symptomatic therapy.

Serum antigenic PK and functional AAT levels were assessed in 21 AATD patients. Dose-related increases in maximal and total INBRX-101 exposure were observed across the dose range of 10 to 120 mg/kg. A terminal half-life of approximately 15 - 19 days was observed. Preliminary data from multiple doses of 40 mg/kg or 80 mg/kg every three weeks showed accumulation in line with the prolonged half-life. Observed trough levels of functional AAT exceeded those reported historically for pdAAT.
