Study Details

Study Description

Brief Summary

The primary objective was to determine the tolerability of a new inhaled formulation of interferon beta-1a when given as a single dose, when given once per week for 4 weeks, and compared with standard intramuscular (IM) AVONEX® when given as a single dose.

The additional objectives were:

To determine the pharmacokinetic (PK) properties of a new inhaled formulation of interferon beta-1a, using an anti-viral cytopathic effect (CPE) assay for human interferon-beta, when given as a single dose, when given once per week for 4 weeks, and compared with standard IM AVONEX® when given as a single dose.

To determine the pharmacodynamic (PD) properties of a new inhaled formulation of interferon beta-1a, as measured by serum neopterin and 2-microglobulin, when given as a single dose, when given once per week for 4 weeks, and compared with standard IM AVONEX® when given as a single dose.

Treatment History

Previous treatment with any interferon beta or any interferon alpha product.
Treatment with another investigational drug or approved therapy for investigational use within 3 months prior to the first day of dosing.
Except for contraceptives, vitamin/mineral supplements, acetaminophen (paracetamol), and/or ibuprofen, treatment with any medication including over-the-counter products within 48 hours prior to the first dose of study drug.

Miscellaneous

History of smoking within 6 months prior to the first day of dosing.
