Alpha interferons, including PEG-Intron, may cause or aggravate fatal or life-threatening neuropsychiatric, autoimmune, ischemic, and infectious disorders. Patients should be monitored closely with periodic clinical and laboratory evaluations. Patients with persistently severe or worsening signs or symptoms of these conditions should be withdrawn from therapy. In many but not all cases these disorders resolve after stopping PEG-Intron therapy. See WARNINGS, ADVERSE REACTIONS.
Use with Ribavirin. Ribavirin may cause birth defects and/or death of the unborn child. Extreme care must be taken to avoid pregnancy in female patients and in female partners of male patients. Ribavirin causes hemolytic anemia. The anemia associated with REBETOL therapy may result in a worsening of cardiac disease. Ribavirin is genotoxic and mutagenic and should be considered a potential carcinogen. (See REBETOL package insert for additional information and other warnings).
PEG-Intron® , peginterferon alfa-2b, Powder for Injection is a covalent conjugate of recombinant alfa-2b interferon with monomethoxypolyethylene glycol (PEG).
PEG-Intron, peginterferon alfa-2b, is indicated for use alone or in combination with REBETOL (ribavirin, USP) for the treatment of chronic hepatitis C in patients with compensated liver disease who have not been previously treated with interferon alpha and are at least 18 years of age.
Published Studies Related to PEG-Intron (Peginterferon Alfa-2B)
Maintenance therapy with peginterferon alfa-2b does not prevent hepatocellular carcinoma in cirrhotic patients with chronic hepatitis C. [2011.06]
BACKGROUND & AIMS: Several studies have reported that low doses of interferon can delay the development of hepatocellular carcinoma (HCC) and progression of chronic hepatitis C. We investigated the incidence of clinical events among participants of the Evaluation of PegIntron in Control of Hepatitis C Cirrhosis (EPIC)3 program... CONCLUSIONS: Maintenance therapy with peginterferon alfa-2b is not warranted in all patients and does not prevent HCC. However, there is a potential clinical benefit of long-term suppressive therapy in patients with preexisting portal hypertension. Copyright (c) 2011 AGA Institute. Published by Elsevier Inc.

Combination therapy of intra-arterial 5-fluorouracil and systemic pegylated interferon alpha-2b for advanced hepatocellular carcinoma. [2011.06]
BACKGROUND: This study evaluated the efficacy of combined 5-fluorouracil (5-FU) and pegylated interferon (PEG-IFN) alpha-2b in patients with advanced hepatocellular carcinoma (HCC)... CONCLUSION: Although a prospective randomized controlled trial using a larger population of patients with advanced HCC is needed to evaluate combination therapy with 5-FU and PEG-IFNalpha-2b, this new combination therapy may be useful for patients with advanced HCC.
Seizures during pegylated interferon and ribavirin therapy for chronic Hepatitis C: observations from the WIN-R trial. [2011.03]
BACKGROUND: Seizures are reported as an uncommon side effect of interferon therapy. AIM: To determine the frequency and presentation of seizures occurring during pegylated interferon-alpha (PEG-IFNalpha) and ribavirin therapy for chronic hepatitis C... CONCLUSIONS: Seizures occur infrequently in patients receiving PEG-IFNalpha-2b plus ribavirin, and appear to be associated with other risk factors including antidepressant use.
Immune modulation of minimal residual disease in early chronic phase chronic myelogenous leukemia: a randomized trial of frontline high-dose imatinib mesylate with or without pegylated interferon alpha-2b and granulocyte-macrophage colony-stimulating factor. [2011.02.01]
BACKGROUND: Most patients with chronic myelogenous leukemia (CML) harbor residual disease, as evidenced by molecular techniques even after treatment with high-dose imatinib (ie, 800 mg/d). Interferon alpha (IFN alpha) is efficacious in CML likely due to its immunomodulatory properties, and is synergistic in vitro with imatinib and granulocyte macrophage-colony stimulating factor (GM-CSF)... CONCLUSIONS: The addition of PEG IFN alpha-2b and GM-CSF to high-dose imatinib therapy does not improve significantly the cytogenetic or molecular response rates compared with high-dose imatinib alone. The high dropout rate in the PEG IFN alpha-2b arm may have compromised its potential immunomodulatory benefit. Copyright (c) 2010 American Cancer Society.
Telaprevir is effective given every 8 or 12 hours with ribavirin and peginterferon alfa-2a or -2b to patients with chronic hepatitis C. [2011.02]
BACKGROUND & AIMS: Recent studies have shown that 12 weeks of treatment with telaprevir, administered every 8 hours (q8h), combined with pegylated interferon (peginterferon) alfa-2a plus ribavirin significantly increased the rate of hepatitis C virus (HCV) eradication (sustained virologic response [SVR]) in patients infected with HCV genotype 1 compared with approved therapy. We investigated the efficacy, safety, tolerability, and pharmacokinetics of telaprevir given q8h or every 12 hours (q12 h) in combination with peginterferon alfa-2a or alfa-2b... CONCLUSIONS: A high proportion (>80%) of patients achieved an SVR regardless of the telaprevir dosing frequency (q8 h or q12 h) or type of peginterferon alfa used (alfa-2a or alfa-2b).

Clinical Trials Related to PEG-Intron (Peginterferon Alfa-2B)
Three Regimens of PEG-Intron Plus Ribavirin in Previously Untreated Chronic Hepatitis C, Genotype 2 or 3 (Study P03548AM2)(COMPLETED) [Completed]
This is a randomized, open-label, multinational study designed to evaluate the "standard"
regimen, PEG-Intron 1. 5 µg/kg subcutaneously once weekly plus ribavirin 800-1200 mg daily
(Arm A), compared to a lower dose regimen, PEG-Intron 1. 0 µg/kg subcutaneously once weekly
plus ribavirin 800-1200 mg daily (Arm B), using a 24 week treatment duration for both arms.
Additionally, the study will examine the efficacy of reduced treatment duration: PEG-Intron
1. 5 Âµg/kg subcutaneously once weekly plus ribavirin 800-1200 mg for 16 weeks (Arm C).
Peg-Ifn Dose Evaluations for Previously Untreated Subjects With Chronic Hepatitis C Infected With Genotype 1 (Study P03471AM1)(COMPLETED) [Completed]
The objective is to compare the safety and efficacy of the following three treatment regimens
in previously untreated adult subjects with chronic hepatitis C infected with Genotype 1: (1)
PEG-Intron 1. 5 µg/kg/wk in combination with weight based REBETOL (800-1400 mg/day); (2)
PEG-Intron 1µg/kg/wk in combination with weight based REBETOL (800-1400 mg/day); and (3)
PEGASYS 180 µg/wk plus COPEGUS 1000-1200 mg/day.
Study of PEG-Intron Plus REBETOL in Pediatric Subjects With Chronic Hepatitis C (Study P02538AM1)(COMPLETED) [Completed]
The primary objective is to assess the safety, efficacy and tolerability of the combination
of PEG-Intron plus REBETOL in pediatric subjects with chronic hepatitis C. The secondary
objective is to measure the multiple-dose pharmacokinetics of PEG-Intron and REBETOL in
pediatric subjects with chronic hepatitis C.
Extended Treatment With PEG-Intron and Rebetol in Patients With Genotype 1 Chronic Hepatitis C and Slow Virologic Response (Study P03685AM3) [Active, not recruiting]
This is a controlled, randomized, parallel-groups, open-label, multinational study designed
to evaluate the efficacy and safety of PEG-Intron plus Rebetol in subjects with chronic
hepatitis C. It is designed to evaluate whether 72 weeks of treatment with PEG-Intron plus
Rebetol is more effective than 48 weeks of treatment in subjects with Genotype 1 chronic
hepatitis C who exhibit a slow response to treatment.
A Phase II Study of an Anti-Tumor Immunotherapy Regimen Comprised of Pegylated Interferon-Alpha 2b and HyperAcute Melanoma Vaccine for Subjects With Advanced Melanoma [Recruiting]
The purpose of this study is to determine the safety of giving subjects with advanced,
recurrent or refractory melanoma the HyperAcute® Melanoma vaccine with a variant of a drug,
called Interferon (PEG-Intron®) that is specially formulated to be given on a weekly basis
(instead of daily). The study vaccine (HyperAcute®-Melanoma) is made from three types of
human melanoma cell lines (grown in the laboratory) in which the genes have been slightly
changed. This clinical study will try to discover the safety of the study vaccine combined
with PEG-IntronÂ®, its side effects and the potential benefits, if any.
