Roferon-A (Interferon Alfa-2A (Recombinant)) - Summary

ROFERON-A SUMMARY

ROFERON^®-A
(Interferon alfa-2a, recombinant)

Roferon-A (Interferon alfa-2a, recombinant) is a sterile protein product for use by injection. Roferon-A is manufactured by recombinant DNA technology that employs a genetically engineered Escherichia coli bacterium containing DNA that codes for the human protein.

Roferon-A is indicated for the treatment of chronic hepatitis C and hairy cell leukemia in patients 18 years of age or older. In addition, it is indicated for chronic phase, Philadelphia chromosome (Ph) positive chronic myelogenous leukemia (CML) patients who are minimally pretreated (within 1 year of diagnosis).

FOR PATIENTS WITH CHRONIC HEPATITIS C: Roferon-A is indicated for use in patients with chronic hepatitis C diagnosed by HCV antibody and/or a history of exposure to hepatitis C who have compensated liver disease and are 18 years of age or older. A liver biopsy and a serum test for the presence of antibody to HCV should be performed to establish the diagnosis of chronic hepatitis C. Other causes of hepatitis, including hepatitis B, should be excluded prior to therapy with Roferon-A.

Antiviral activity of danoprevir (ITMN-191/RG7227) in combination with pegylated interferon alpha-2a and ribavirin in patients with hepatitis C. [2011.08.15]
BACKGROUND: Current therapy options for patients with chronic hepatitis C virus (HCV) infection genotype 1 are effective in <50%. Danoprevir (ITMN-191/RG7227) is a potent, selective, and orally active inhibitor of the HCV NS3/4A serine protease... CONCLUSIONS: Our study showed substantial antiviral efficacy of danoprevir in combination with pegylated interferon alpha-2a and ribavirin. Exploration of the safety and antiviral efficacy of danoprevir in longer clinical studies is warranted.

Randomised clinical trial: efficacy of peginterferon alfa-2a in HBeAg positive chronic hepatitis B patients with lamivudine resistance. [2011.08]
BACKGROUND: Previous studies suggested that a finite course of peginterferon alfa-2a may offer an alternative rescue therapy for patients with lamivudine resistance. However, because of the limitation of study design and small sample size, it is difficult to make definitive conclusion. AIM: To explore the role of peginterferon alfa-2a, in the rescue treatment of HBeAg-positive chronic hepatitis B patients with lamivudine resistance... CONCLUSIONS: Overall, the response to peginterferon alfa-2a among patients with lamivudine resistance was suboptimal. HBeAg seroconversion rate at week 72 by 48 weeks peginterferon alfa-2a treatment was higher than continuous adefovir therapy. Monitoring HBsAg levels can help to predict response to peginterferon alfa-2a. (c) 2011 Blackwell Publishing Ltd.

High-dose pegylated interferon-alpha and ribavirin in nonresponder hepatitis C patients and relationship with IL-28B genotype (SYREN trial). [2011.07]
BACKGROUND &#38; AIMS: In patients with chronic hepatitis C who failed to respond to standard therapy, high-dose pegylated interferon (IFN)-alpha and/or ribavirin could induce a stronger antiviral response and prevent treatment failure and HCV resistance when combined with direct-acting antivirals. The influence of genetic determinants in this context remains unknown... CONCLUSIONS: High-dose pegylated IFN-alpha with standard or high doses of ribavirin induces a potent antiviral response in a substantial number of patients who did not respond to standard therapy. The IL-28B genotype is an independent predictor of the antiviral response. High-dose pegylated IFN-alpha in combination with ribavirin and protease inhibitors appears as an attractive option for future study in this population. Copyright (c) 2011 AGA Institute.

Twice-weekly pegylated interferon-alpha-2a and ribavirin results in superior viral kinetics in HIV/hepatitis C virus co-infected patients compared to standard therapy. [2011.06.01]
CONCLUSION: Our results, when confirmed in larger randomized clinical trials, may provide a novel therapeutic approach to improve SVR among HIV/HCV co-infected patients, especially African-American patients.

Coffee consumption is associated with response to peginterferon and ribavirin therapy in patients with chronic hepatitis C. [2011.06]
BACKGROUND &#38; AIMS: High-level coffee consumption has been associated with reduced progression of pre-existing liver diseases and lower risk of hepatocellular carcinoma. However, its relationship with therapy for hepatitis C virus infection has not been evaluated... CONCLUSIONS: High-level consumption of coffee (more than 3 cups per day) is an independent predictor of improved virologic response to peginterferon plus ribavirin in patients with hepatitis C.

Clinical Trials Related to Roferon-A (Interferon Alfa-2A)

Thymosin Alpha 1, Interferon Alpha, or Both, in Combination With Dacarbazine in Patients With Malignant Melanoma [Completed]
The purpose of the study is to test safety and efficacy of different doses of thymosin alpha 1 (1. 6 mg, 3. 2 mg, and 6. 4 mg) in combination with dacarbazine and with or without Interferon alpha in treating patients affected by stage IV melanoma. Primary end-point is Tumor Response evaluated according to Response Evaluation Criteria In Solid Tumors (RECIST). Secondary end-points are Overall Survival and Progression Free Survival. Ninety-five patients are allocated to each arm to test the hypothesis that P0 <= 0. 05 vs the alternative hypothesis that P1 >= 0. 15 (alpha = 5%, within-group statistical analysis beta = 95%).

Recombinant Interferon Alpha and Etoposide in Relapsed Osteosarcoma [Completed]
Primary Objectives: 1. To determine the efficacy of combining Interferon Alpha (IFN) with etoposide for the treatment of relapsed osteosarcoma. 2. To determine if IFN alters the plasma pharmacokinetics of etoposide. 3. To determine the toxicities of IFN and etoposide when administered together. 4. To determine IFN blood levels following combination therapy.

Zidovudine, Interferon Alfa-2b, and PEG-Interferon Alfa-2b in Treating Patients With Human T-Cell Lymphotropic Virus Type 1-Associated Adult T-Cell Leukemia/Lymphoma [Terminated]
RATIONALE: Human T-cell lymphotropic virus type 1 can cause cancer. Zidovudine is an antiviral drug that acts against the human T-cell lymphotropic virus type 1. Giving zidovudine, interferon alfa-2b, and PEG-interferon alfa-2b together may stimulate the immune system and slow down or keep the cancer cell from growing. PURPOSE: This clinical trial is studying how well giving zidovudine together with interferon alfa-2b and PEG-interferon alfa-2b works in treating patients with human T-cell lymphotropic virus type 1-associated adult T-cell leukemia/lymphoma.

Reactogenicity, Immunogenicity of Trivalent Influenza Vaccine With Recombinant Interferon Alpha Among Chronic Lymphocytic Leukemia [Withdrawn]
The goal of this clinical study is to learn if Pegasys (pegylated interferon) or Roferon (interferon) can make the Trivalent Inactivated Influenza vaccine (TIV) more effective in increasing the body's immune reaction against the flu virus in patients with Chronic Lymphocytic Leukemia (CLL).

Recombinant Interferon Alfa-2b in Treating Patients With Melanoma [Active, not recruiting]
This pilot clinical trial studies recombinant interferon alfa-2b in treating patients with melanoma. Recombinant interferon alfa-2b may interfere with the growth of tumor cells and slow the growth of melanoma
