A phase II multicenter study evaluating combination immunotherapy with pembrolizumab and peginterferon alfa-2b for advanced cholangiocarcinoma.

Pembrolizumab was present in pts with elevated CC in Phase I studies. Interferon alpha-2b has been shown to raise tumor immune infiltrates. We recommend combining sylatron and pem in an open-label, single-arm, multicenter Phase II research in order to raise the response rate of pts with CC to pem. Forty-four pts will be on trial for SC sylatron weekly for 12 weeks, and IV pem once a week for three weeks, or until pts experience disease progression or unacceptable toxicity, or refuse consent, or withdraw consent. One biopsy will be obtained before the start of sylatron therapy and another after the third but not before the fourth injection of sylatron. Using biopsies 1 and 2, the effect of sylatron on the CC immune microenvironment will be investigated.

Virological Escape in HCV Genotype-1-Infected Patients Receiving Daclatasvir plus Ribavirin and Peginterferon Alfa-2A or Alfa-2B

Daclatasvir is a picomolar inhibitor of HCV non-structural protein 5A and has demonstrated effectiveness in patients chronically infected with HCV. Methods In the double-blind, randomized trials AI444021 and AI444022, 71 Japanese patients chronically infected with HCV genotype 1 and e11, 1 received DCV plus peginterferon alfa-2b, and ribavirin. In 14% of treatment-naive patients and 54% of former alfa/ribavirin non-responders, there was a virological error. Resistance testing was carried out on baseline samples and samples with HCV RNAu22651,000 IU/ml at week 1 through to post-treatment week 24. At the time of failure, all patients with virological failure had NS5A DCV-resistant variants. Significant decrease in DCV antiviral activity was generally limited to u2265 two resistance-associated NS5A substitutes. Conclusions HCV genotype 1b treatment-naive Japanese patients receiving DCV plus alfa-2a/ribavirin or alfa-2b/ribavirin was associated with increased enrichment of NS5A resistance variants L31V/M-Y93H.

A Randomized Trial of Daclatasvir with Peginterferon Alfa-2B and Ribavirin for HCV Genotype 1 Infection

Background Daclatasvir-containing regimens are expected to improve existing regimens by combining peginterferon alfa and ribavirin with first-generation protease inhibitors for treatment of chronic HCV genotype 1 infection. For 24 weeks, protocol-defined response Daclatasvir recipients with protocol-defined responses were treated; those without protocol-defined response and placebo recipients continued therapy until week 48. In the daclatasvir 10 mg, 60 mg, and placebo groups, respectively, sustained virological response 24 weeks post-treatment with 67. 7%, 90. 0%, and 62. 5% of treatment-naive patients. Conclusions Daclatasvir 60 mg as a combination of peginterferon alfa-2b and ribavirin produced a high incidence of SVR 24 in treatment-naive patients with HCV genotype 1 infection, with tolerability similar to that of peginterferent alfa-2b/ribavirin alone.

U.S. Food and Drug Administration Approval: Peginterferon-alfa-2b for the Adjuvant Treatment of Patients with Melanoma

Abstract Learning Objectives After completing this course, the reader will be able to: Describe the situation in which peginterferon-alfa-2b is used to treat melanoma patients. Describe the learning objectives in patients with melanoma patients. Following definitive surgical resection, complete lymphadenectomy, complete hemoglobectomy, CME's On March 29, 2011, the U. S. Food and Drug Administration approved peginterferon alfa-2b for the adjuvant treatment of melanoma patients with microscopic or gross nodal involvement following definitive surgical resection including complete lymphadenectomy. www. cance. com PEG-IFN patients, 33 percent, discontinued therapy due to adverse reactions. Two deaths were confirmed within 30 days of the last therapy dose, two due to cardiovascular disease that could be possibly related to treatment.

Peginterferon alfa-2b and ribavirin combination therapy for chronic hepatitis C

Since 2001, Pegylated interferon and ribavirin have been the gold standard treatment for chronic hepatitis C. Hepatitis C is the most common blood-borne disease in the United States and the leading cause of cirrhosis requiring liver transplantation. For most healthcare professionals, having understanding of the medications used for CHC therapy is highly recommended.

Cost-effectiveness analysis of treatment with peginterferon-alfa-2a versus peginterferon-alfa-2b for patients with chronic hepatitis C under the public payer perspective in Brazil

Abstract Background: Chronic hepatitis C affects approximately 170 million people worldwide, making it one of the leading causes of chronic liver disease. About 20% of patients with chronic hepatitis C will experience cirrhosis over 20 years, and there is an elevated risk of experiencing hepatic dysfunction. In the Brazilian Public Health System's study, pegylated interferon-alfa-2a versus pegylated interferon-alfa-2b's treatment costs and results were compared to ribavirin-based pegylated interferon-alfa-2a and genotype 1, respectively. Conclusion These results show that treatment with peginterferon-alfa-2a is more cost-effective and less costly than peginterferon-alfa-2b in Brazil, as compared to peginterferon-alfa-2b.
