None of the approved immunomodulatory drugs in adults Multiple Sclerosis (MS) patients have been officially approved for the pediatric patients and are currently used off-label in this population. In this study, we evaluated the effectiveness and tolerability of intramuscular interferon beta1-a (Avonex(®)) and subcutaneously injected interferon beta1-b (Betaferon(®)) in children with definite r...

Beta interferon − INF 1b: Betaferon® and Extavia® (vial 250 g) INF 1a: Avonex® (vial 30 g); Rebif® (vial 22–44 g). Both also in syringes and preloaded containers. RR MS Pseudo-fever syndrome, depression, psychiatric disorders, moderate myelosuppression, hypotension, high liver enzymes, cough, dyspnea, proteinuria, OHT, hyperuricemia, KI, neuropathy, confusion, edema, hair loss, digestive altera...

Treatment with interferon beta (IFN-β) induces the production of binding antibodies (BAbs) and neutralizing antibodies (NAbs) in patients with multiple sclerosis (MS). NAbs against IFN-β are associated with a loss of IFN-β bioactivity and decreased clinical efficacy of the drug. The objective of this study was to evaluate the incidence and the prevalence of binding antibodies (BAbs) and neutral...

Determining to what extent biophysical characteristics of aggregates affect immunogenicity of therapeutic interferon beta-1b. Three recombinant human interferon beta-1b (rhIFNβ-1b) samples with different levels of aggregates generated by copper oxidation, thermal stress, or left untreated, as well as Avonex(®) drug substance and Betaferon(®) drug product, were injected intraperitoneally in nont...

BACKGROUND Disease-modifying drugs (DMDs) are a significant expenditure for treating multiple sclerosis (MS). However, there is limited report on assessment of the cost-utility of DMDs compared with symptom management in the presence of long-term data. This study aimed to assess the lifetime cost-utility from the Iranian healthcare perspectives of 4DMDs relative to symptom management alone in p...

There are many reports suggesting an association between vitamin D status and both the development of multiple sclerosis (MS) and its course. This relationship and the effects of vitamin D and interferon β-1b (IFNβ-1b) in the treatment of patients are reviewed in the BEtaferon/ Betaseron in Newly Emerging multiple sclerosis For Initial Treatment (BENEFIT) and the Betaferon/Betaseron Efficacy Yi...

BACKGROUND The efficacy of interferon beta (IFN beta) is well established in relapsing-remitting multiple sclerosis (MS). However, the use of this drug in clinical practice is complex, especially because it is only partially effective, its long term efficacy and side effects are unknown, its efficacy may be abrogated by the development of neutralising antibodies, compliance is variable, and its...
