ARALAST® NP [Alpha1-Proteinase Inhibitor (Human)] is an Alpha1-Proteinase Inhibitor (Alpha1-PI) indicated for chronic augmentation therapy in adults with clinically evident emphysema due to severe congenital deficiency of Alpha1-PI (alpha1-antitrypsin deficiency).

ARALAST NP increases antigenic and functional (anti-neutrophil elastase capacity, ANEC) serum levels and antigenic lung epithelial lining fluid levels of Alpha1-PI. No randomized, controlled trials have demonstrated effects of augmentation therapy on pulmonary exacerbations or emphysema progression. Clinical data on long-term effects of ARALAST NP therapy are not available.

Please see full Indication and Limitations of Use below.

Know Alpha1-antitrypsin deficiency

Treating your patients with clinically evident emphysema due to severe congenital Alpha1-antitrypsin deficiency begins with understanding their condition.

Alpha1 deficiency is a hereditary disorder characterized by low serum and lung levels of Alpha1-PI.1

Severe variants are associated with slowly progressive emphysema, which manifests in the third to fourth decades of life.1

Augmentation therapy is indicated in patients with severe phenotypic variants who have clinically evident emphysema.1

Inheritance is in an autosomal codominant fashion.1

Learn about augmentation therapy

ARALAST NP is lyophilized for reconstitution and administered to patients as a once-weekly infusion.1

The recommended weekly dosage for ARALAST NP is 60 mg/kg.1

Administer ARALAST NP at a rate not to exceed 0.2 mL per kg body weight per minute, and as determined by the response and comfort of the patient.1

You and your patients can decide which setting is right for them.

ARALAST NP was proven to increase Alpha1-PI levels in a clinical trial.1

In a clinical trial, augmentation therapy with ARALAST NP was administered once weekly to patients with congenital Alpha1 deficiency at a dose of 60 mg/kg.*†1

During weeks 8 through 11 of the clinical trial, steady-stage trough levels of serum antigenic and functional Alpha1-PI remained above the 11 µM theoretical protective level.1

There were no deaths and no serious adverse reactions associated with ARALAST NP or ARALAST administration in clinical trials. The most common adverse reactions (>0.5% of infusions) in clinical trials were headache and upper respiratory infection.1

*Study Design: ARALAST NP was evaluated in a randomized, double-blind trial with partial crossover involving 26 Alpha1-PI deficient patients receiving ARALAST NP (n=13) or the comparator (n=13) at a dose of 60 mg/kg IV per week for 10 consecutive weeks. Following the first 10 weekly infusions, all patients received ARALAST NP at 60 mg/kg IV per week. The objectives of the study were to: demonstrate the pharmacokinetics of antigenic and/or functional Alpha1-PI in ARALAST NP were not inferior to the control; and determine whether ARALAST NP maintained antigenic and/or functional Alpha1-PI of at least 11 µM (57 mg/dL). A second clinical trial in 13 patients with severe congenital Alpha1-PI deficiency evaluated safety and effects of weekly augmentation therapy on levels of Alpha1-PI in the epithelial lining fluid.1

The effect of augmentation therapy on pulmonary exacerbations and on the progression of emphysema in Alpha1-antitrypsin deficiency has not been conclusively demonstrated in randomized, controlled clinical trials.1
