Study Arms:
- Part 1a(Aralast NP)-Subjects Aged 16-35 Yrs (Type: EXPERIMENTAL): Subjects aged 16-35 years at enrollment with new-onset type 1 diabetes mellitus (T1DM) received Aralast NP 45 mg/kg by intravenous (IV) infusion once a week for 6 weeks. Following the Week 6 infusion, participants underwent a minimum 3-week washout period. After the washout period, each participant proceeded to a high dose of Aralast NP 90 mg/kg by IV infusion for the next 6 weeks, for a total of 12 infusions.
- Part 1a (Aralast NP)-Subjects 8-15 Yrs (Type: EXPERIMENTAL): Subjects aged 8-15 years at enrollment with new-onset type 1 diabetes mellitus (T1DM) received Aralast NP 45 mg/kg by IV infusion once a week for 6 weeks. Following the Week 6 infusion, participants underwent a minimum 3-week washout period. After the washout period, each participant proceeded to a high dose of Aralast NP 90 mg/kg by IV infusion for the next 6 weeks, for a total of 12 infusions.
- Part 1b (Aralast NP)--Subjects Aged 18-35 Yrs (Type: EXPERIMENTAL): Aralast NP 90 mg/kg/wk by IV infusion once a week for 6 weeks. Following the Week 6 infusion, participants undergo a minimum 3-wk washout period than then, each participant proceeds to high dose Aralast NP 180 mg/kg/wk by IV infusion for the next 6 weeks, for a total of 12 infusions.
- Part 1b (Aralast NP)-Subjects 8-17 Yrs (Type: EXPERIMENTAL): Aralast NP 90 mg/kg/wk by IV infusion once a week for 6 weeks. Following the Week 6 infusion, participants undergo a minimum 3-wk washout period than then, each participant proceeds to high dose Aralast NP 180 mg/kg/wk by IV infusion for the next 6 weeks, for a total of 12 infusions.
