| NCT00047879 ↗ | Phase II Trial of Peginterferon Alpha-2b and Thalidomide in Adults With Recurrent Gliomas | Completed | National Cancer Institute (NCI) | Phase 2 | 2002-10-01 | This study will examine the safety and effectiveness of peginterferon alpha-2b (PEG-Intron) alone and together with thalidomide in patients with gliomas (a type of brain tumor). Gliomas are nourished by blood delivered through blood vessels whose formation is stimulated by substances produced by the tumor itself. Stopping the growth of new vessels can slow or prevent tumor growth. The Food and Drug Administration has approved various interferons for treating several diseases, including melanoma and some leukemias. These drugs block new vessel growth in patients with recurrent tumors, but in high doses they produce serious side effects. Therefore, this study will use a low dose of PEG-Intron given weekly instead of high doses given several times a week. Thalidomide, currently approved to treat leprosy, also blocks development of new blood vessel formation. In a recent study of thalidomide given to 36 patients with gliomas, 4 patients had tumor shrinkage, 12 had stable disease for at least 2 months, and at least 3 had responses to treatment lasting 6 to 14 months. Patients 18 years of age and older with a primary glioma whose tumor has recurred or is growing following standard treatment and does not respond to radiation therapy may be eligible for this study. Candidates will be screened with a physical examination, blood and urine tests (including a pregnancy test for women of childbearing potential), and magnetic resonance imaging (MRI) or computed tomography (CT) of the head. Patients will continue treatment cycles as long as the drug is tolerated without serious side effects and the tumor is not growing. While on the study, patients will undergo various tests and procedures as follows: Physical and neurologic examinations every 6 weeks MRI or CT brain scan every 6 weeks to assess tumor status. MRI is a diagnostic test that uses a strong magnetic field and radio waves to show structural and chemical changes in tissues. During the scan, the patient lies on a table in a narrow cylinder containing a magnetic field. He or she can speak with a staff member through an intercom system at all times during the procedure. |
| NCT00048945 ↗ | Efficacy and Safety Study of Pegasys in the Treatment of Chronic Hepatitis B | Completed | Hoffmann-La Roche | Phase 3 | 2002-01-01 | The purpose of this study is to determine the safety and efficacy of Pegasys + placebo + lamivudine versus lamivudine alone in patients with lamivudine versus lamivudine alone in patients with hepatitis B antigen CHB. |
| NCT00056862 ↗ | Low-Dose Peginterferon and Ribavirin to Treat Chronic Hepatitis C in Patients Infected With HCV Genotype 2 or 3 | Completed | National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) | Phase 4 | 2003-03-01 | This study will examine the effectiveness of low-dose peginterferon and ribavirin therapy for certain patients with chronic hepatitis C-a liver disease that, in some patients, can progress to cirrhosis of the liver, liver cancer, and liver failure. |
| NCT00077636 ↗ | ACCELERATE Study - A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) in Combination With COPEGUS (Ribavirin) in Interferon-Naive Patients With Chronic Hepatitis C (CHC) Infection. | Completed | Hoffmann-La Roche | Phase 4 | 2003-12-01 | This study will evaluate the efficacy and safety of different durations of treatment with PEGASYS combined with ribavirin in patients with CHC genotype 2 or 3 infection who have never previously received interferon (IFN) therapy. The anticipated time on study treatment is 3-12 months and the target sample size is 500+ individuals. |
| NCT00077649 ↗ | A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) in Combination With COPEGUS (Ribavirin) in Interferon-Naive Patients With Chronic Hepatitis C Infection (CHC). | Completed | Hoffmann-La Roche | Phase 4 | 2004-01-01 | The effects of treatment with different doses of PEGASYS in combination with different doses of ribavirin will be evaluated in patients with CHC genotype 1 who have a high viral titer, body weight greater than 85kg (187lbs) and no prior treatment with interferon. The anticipated time on study treatment is 3-12 months and the target sample size is 100-500 individuals. |
| NCT00081770 ↗ | Peginterferon Dose Evaluations for Previously Untreated Subjects With Chronic Hepatitis C Infected With Genotype 1 (Study P03471) | Completed | Merck Sharp & Dohme Corp. | Phase 3 | 2004-03-01 | 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) PegIntron 1.5 µg/kg/wk in combination with weight based REBETOL (800-1400 mg/day); (2) PegIntron 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. |
| NCT00085917 ↗ | Peginterferon Alpha-2a and Ribavirin to Treat Hepatitis C in HIV-infected Patients | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 2 | 2004-06-01 | This study will evaluate the safety and effectiveness of combination therapy with peginterferon alpha-2a and ribavirin for treating hepatitis C virus (HCV) infection in HIV-infected patients. Peginterferon alpha with ribavirin is the therapy of choice for people with HCV alone. Peginterferon alpha-2a is a compound that results from attaching a polyethylene glycol molecule to interferon alpha-2a. This compound stays in the blood longer than unmodified interferon alpha-2a, causing a higher blood concentration and thus maintaining greater activity against the hepatitis C virus. HIV-infected patients 18 years of age and older with chronic hepatitis C infection and a viral load greater than 2000 copies/mL may be eligible for this 2-1/2 year study. Candidates are screened with a medical history and physical examination, blood and urine tests, eye examination, chest x-ray, electrocardiogram (EKG), liver ultrasound, and pregnancy test in women who are able to become pregnant. If a recent liver biopsy is not available, this test is done to determine the type and severity of liver disease. The patient is given a sedative before the procedure. Then, the skin in the area over the biopsy site is numbed with a local anesthetic and a needle is inserted rapidly into and out of the liver to obtain a small tissue sample. The patient remains in the hospital overnight for monitoring. Participants begin treatment with injections under the skin of peginterferon alpha-2a and ribavirin pills by mouth on study day 0. Peginterferon is given either once or twice a week for 4 weeks and then once a week for 44 weeks. Ribavirin is given daily. In addition, patients continue to take all other medications prescribed by their doctor. Clinic visits are scheduled for the following procedures: - Days 1, 3, 4, 7, 10 and weeks 2, 3, and 4 - Blood tests for safety measures and to measure blood levels of HIV and HCV. - Weeks 6, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44 - Blood and urine tests to determine the side effects of treatment and its effect on the HCV infection. In addition, eye examinations are done every 3 months, and pregnancy and thyroid function tests are done several times during the treatment period. - Week 48 or end of treatment - Treatment stops after 48 weeks. At this time, or earlier for those who do not complete the 48 weeks, patients return to the clinic for a chest x-ray, EKG, blood tests, and abdominal ultrasound. Patients are hospitalized for a repeat liver biopsy. - Weeks 52, 56, 64 and 72 - Blood and urine tests to determine the side effects of treatment and its effect on the HCV infection, and a urine pregnancy test in women. |
