AIMS To evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of subcutaneous peginterferon beta-1a in patients with relapsing-remitting multiple sclerosis (RRMS) in the phase 3 ADVANCE study (n = 1512). METHODS During year 1, patients were randomized (1:1:1) to placebo or peginterferon beta-1a 125 μg every 2 or 4 weeks. After year 1, patients randomized to placebo were re-randomized t...

background: the refolding of proteins from inclusion bodies is affected by several factors, including solubilization of inclusion bodies by denaturants, removal of the denaturant, and assistance of refolding by small molecule additives. objectives: the purpose of this study was optimization of recombinant human interferon-b purification in order to achieve higher efficiency, yield, and a produc...

Introduction: Interferon beta is one of the members of type I interferons. Creating R27T and V101F mutations is one of the important researches performed to improve function, decrease immunogenicity, increase expression and increase half-life of interferon beta. In this study, the effects of R27T and V101F mutations on interferon beta binding to interferon receptors were studied by molecular do...

Acute inflammation is associated with cognitive deficits and alterations of cortical plasticity in multiple sclerosis (MS). We tested whether early treatment with high-dose interferon (IFN) beta-1a, known to reduce inflammatory activity, improves cortical function and cognitive deficits in MS. Eighty treatment-naïve relapsing-remitting MS (RRMS)patients received IFN beta-1a (44 mcg) subcutaneously ...
