All Clinical Trials for boceprevir
| Trial ID | Title | Status | Sponsor | Phase | Start Date | Summary |
|---|---|---|---|---|---|---|
| NCT00160251 ↗ | Boceprevir (SCH 503034) Plus Peg-Intron, With and Without Added Ribavirin, in Patients With Chronic Hepatitis C, Genotype 1, Who Did Not Respond to Previous Treatment With Peginterferon Alfa Plus Ribavirin (Study P03659AM2)(COMPLETED) | Completed | Merck Sharp & Dohme Corp. | Phase 2 | 2005-09-01 | The primary objective of this study is to determine the safe and effective dose range of boceprevir (SCH 503034) in combination with PEG-Intron in adult subjects who have chronic hepatitis C without cirrhosis, and who have failed an adequate course of combination therapy with peginterferon-alfa plus ribavirin. A secondary objective is to explore whether ribavirin provides an additional benefit when combined with PEG-Intron plus boceprevir. |
| NCT00423670 ↗ | Safety and Efficacy of SCH 503034 in Previously Untreated Subjects With Chronic Hepatitis C Infected With Genotype 1 (Study P03523) | Completed | Merck Sharp & Dohme Corp. | Phase 2 | 2007-01-01 | This was an open-label, randomized safety and efficacy trial in adult, treatment-naïve Chronic Hepatitis C (CHC) participants with genotype 1 infection. The study conducted in 2 parts, compared standard-of-care PegIntron (1.5 μg/kg, once weekly [QW]), plus ribavirin (800 to 1400 mg/day), for 48 weeks to five treatment paradigms containing boceprevir (SCH 503034) 800 mg thrice a day (TID). The five treatments included boceprevir (BOC) plus standard-of-care for 28 or 48 weeks, with and without a 4-week lead-in with PegIntron (PEG) and ribavirin (RBV), and exploration of PegIntron plus low-dose ribavirin (400 to 1000 mg/day) plus boceprevir for 48 weeks. |
| NCT00689390 ↗ | Three-year Follow-up of Participants After Administration of Boceprevir or Narlaprevir for the Treatment of Chronic Hepatitis C (P05063) | Terminated | Merck Sharp & Dohme Corp. | Phase 2/Phase 3 | 2007-02-20 | Study P05063 is a 3-year long-term follow-up (LTFU) study in participants previously treated with boceprevir (BOC) or narlaprevir (NAR) in a Phase 1, 2, or 3 clinical study. Participants will be followed for up to 3.5 years after the end of their participation in the treatment protocol to document maintenance of the antiviral response (for sustained responders) and to characterize the long-term safety after use of this therapeutic regimen. LTFU procedures include collection of plasma samples for measuring Hepatitis C Virus ribonucleic acid (HCV-RNA) by polymerase chain reaction (PCR) and HCV sequence analysis. No drug therapy will be administered as part of this study. |
| NCT00705432 ↗ | Safety and Efficacy of Boceprevir in Previously Untreated Subjects With Chronic Hepatitis C Genotype 1 (Study P05216AM2) (COMPLETED) | Completed | Merck Sharp & Dohme Corp. | Phase 3 | 2008-08-01 | This study involves treatment with boceprevir or placebo in combination with PegIntron (PEG) + Ribavirin (RBV) (weight-based dosing [WBD]) in previously untreated adult participants with chronic hepatitis C (CHC) genotype 1. It is hypothesized that the addition of a third active anti- Hepatitis C Virus (anti-HCV) drug may lead to more rapid viral response than therapy with two drugs, and therefore, the addition of boceprevir to PegIntron plus ribavirin therapy after a 4-week lead-in period may allow for both increased rates of sustained virologic response (SVR) and shorter treatment durations (in some populations) than treatment with PegIntron plus ribavirin alone. The study includes two separate cohorts, Cohort I (White participants) and Cohort II (Black participants). Participants from each cohort are assigned (randomized) to one of three study arms, all of which have a 4-week lead-in period with (PEG + RBV). |
| NCT00708500 ↗ | Boceprevir in Subjects With Chronic Hepatitis C Genotype 1 Who Failed Prior Treatment With Peginterferon/Ribavirin (Study P05101AM3)(COMPLETED) | Completed | Merck Sharp & Dohme Corp. | Phase 3 | 2008-08-01 | This study involves treatment with boceprevir or placebo in combination with pegylated interferon alfa-2b (PegIntron, PEG2b) + Ribavirin (RBV) (weight-based dosing [WBD]) in adult subjects with chronic hepatitis C (CHC) genotype 1 who demonstrated interferon responsiveness (a decrease in hepatitis C virus RNA [HCV-RNA] viral load >=2 log10 by Week 12 or undetectable HCV-RNA at end of treatment) but who failed to achieve sustained virologic response (SVR) on prior treatment with any combination therapy of peginterferon alpha and RBV. This trial includes three arms, one control arm (PEG2b + RBV for 48 weeks) and two experimental arms (PEG2b + RBV + boceprevir). One of the experimental arms, Arm 3, consists of treatment with all three drugs for 44 weeks after the lead-in. The other experimental arm, Arm 2, consists of all three drugs for 32 weeks after the lead-in. Participants in Arm 2 who were undetectable for HCV-RNA at Treatment Week 8 will complete treatment at that point. Those who were not undetectable for HCV-RNA at Treatment Week 8 will receive an additional 12 weeks of PEG2b + RBV + boceprevir placebo. It is hypothesized that the addition of a third active anti-HCV drug may lead to more rapid viral response than therapy with two drugs, and therefore, the addition of boceprevir to PEG2b plus RBV therapy after a 4-week lead-in period may allow for both increased rates of SVR and shorter treatment durations (in some populations) than treatment with peginterferon plus RBV alone. |
| NCT00845065 ↗ | Boceprevir in Combination With Peginterferon Alfa-2a and Ribavirin in Participants With Chronic Hepatitis C Genotype 1 Who Failed Prior Treatment With Peginterferon/Ribavirin (Study P05685AM2)(COMPLETED) | Completed | Merck Sharp & Dohme Corp. | Phase 3 | 2009-02-01 | Based on previous experience with peginterferon alfa-2b/ribavirin in combination with boceprevir, the combination with peginterferon alfa- 2a/ribavirin and boceprevir is expected to be safe and well tolerated. Given the wide utilization of both peginterferons and the clear benefit of the addition of boceprevir to peginterferon alfa-2b/ribavirin, it is important to demonstrate the safety and efficacy of boceprevir in combination with peginterferon alfa-2a/ribavirin. |
| NCT00910624 ↗ | Boceprevir Treatment in Participants With Chronic Hepatitis C Genotype 1 Deemed Nonresponders to Peginterferon/Ribavirin (P05514) | Completed | Merck Sharp & Dohme Corp. | Phase 3 | 2009-06-22 | This is a single-arm, multicenter study of boceprevir (BOC) in combination with peginterferon plus ribavirin (PEG/RBV) in adult chronic hepatitis C (CHC) genotype 1 participants who completed their per-protocol defined treatment and did not achieve sustained viral response (SVR) while in the PEG/RBV control arm(s) of an Schering-Plough Research Institute (SPRI) study of BOC combination therapy. Participants who are able to enroll in this study within 2 weeks after the last dose of PEG/RBV in previous protocol are to receive BOC+ PEG/RBV for up to 44 weeks followed by 24 weeks post-treatment follow-up. Participants who are not able to enroll in this study within 2 weeks after the last dose of PEG/RBV in previous protocol are to receive PEG/RBV for 4 weeks followed by BOC+ PEG/RBV for up to 44 weeks, with 24 weeks post-treatment follow-up. |
