All Clinical Trials for HEPSERA
Trial ID | Title | Status | Sponsor | Phase | Start Date | Summary |
---|---|---|---|---|---|---|
NCT00158704 ↗ | Continued Access Study of Adefovir Dipivoxil (ADV) for Patients w/Chronic HBV Infection. | Terminated | Gilead Sciences | N/A | 2002-01-01 | Provide adefovir dipivoxil (Hepsera) 10 mg once daily to patients with chronic hepatitis B virus (HBV) infection who have completed a Gilead-sponsored study of adefovir dipivoxil and require continued access to adefovir dipivoxil. |
NCT00158717 ↗ | Observational Study of the Durability of Seroconversion Chronic HBV Patients Who Seroconverted in a Previous Gilead-Sponsored Study of ADV. | Completed | Gilead Sciences | 2003-04-01 | To investigate the durability of HBeAg seroconversion in patients with chronic hepatitis B virus infection (HBV) who have seroconverted while participating in a previous Gilead-sponsored study of adefovir dipivoxil. | |
NCT00230477 ↗ | Hepsera Versus Hepsera Plus Lamivudine for Treatment of Chronic Hepatitis B in Patients With Normal ALT | Completed | Gilead Sciences | Phase 4 | 2003-04-01 | This project is a randomized, open-label trial of adefovir dipivoxil (Hepsera) and lamivudine combination therapy versus adefovir dipivoxil (Hepsera) monotherapy. Both adefovir dipivoxil and lamivudine are nucleoside analogues approved by the U.S. FDA for the treatment of chronic hepatitis B. The primary hypothesis is that subjects treated with combination therapy will see their viral DNA count decrease in an amount greater than subjects treated with monotherapy. The secondary hypothesis is that subjects treated with combination therapy will have a higher HBeAg conversion rate compared to historical controls of subjects treated with lamivudine or adefovir dipivoxil monotherapy. |
NCT00230477 ↗ | Hepsera Versus Hepsera Plus Lamivudine for Treatment of Chronic Hepatitis B in Patients With Normal ALT | Completed | GlaxoSmithKline | Phase 4 | 2003-04-01 | This project is a randomized, open-label trial of adefovir dipivoxil (Hepsera) and lamivudine combination therapy versus adefovir dipivoxil (Hepsera) monotherapy. Both adefovir dipivoxil and lamivudine are nucleoside analogues approved by the U.S. FDA for the treatment of chronic hepatitis B. The primary hypothesis is that subjects treated with combination therapy will see their viral DNA count decrease in an amount greater than subjects treated with monotherapy. The secondary hypothesis is that subjects treated with combination therapy will have a higher HBeAg conversion rate compared to historical controls of subjects treated with lamivudine or adefovir dipivoxil monotherapy. |
NCT00230477 ↗ | Hepsera Versus Hepsera Plus Lamivudine for Treatment of Chronic Hepatitis B in Patients With Normal ALT | Completed | University of Washington | Phase 4 | 2003-04-01 | This project is a randomized, open-label trial of adefovir dipivoxil (Hepsera) and lamivudine combination therapy versus adefovir dipivoxil (Hepsera) monotherapy. Both adefovir dipivoxil and lamivudine are nucleoside analogues approved by the U.S. FDA for the treatment of chronic hepatitis B. The primary hypothesis is that subjects treated with combination therapy will see their viral DNA count decrease in an amount greater than subjects treated with monotherapy. The secondary hypothesis is that subjects treated with combination therapy will have a higher HBeAg conversion rate compared to historical controls of subjects treated with lamivudine or adefovir dipivoxil monotherapy. |
NCT00307489 ↗ | Treatment of Persistent Viremia (Virus in Blood) in Chronic Hepatitis B Subjects Already Receiving Adefovir Dipivoxil | Completed | Gilead Sciences | Phase 2 | 2006-03-01 | This study explores the efficacy, safety and tolerability of tenofovir DF (TDF) 300 mg once daily monotherapy versus the combination of emtricitabine 200 mg plus tenofovir DF 300 mg (FTC/TDF) once daily in subjects currently being treated with adefovir dipivoxil (Hepsera) for chronic hepatitis B who have persistent viral replication (detectable hepatitis B virus deoxyribonucleic acid [HBV DNA]). Subjects with confirmed (within 4 weeks) plasma HBV DNA ≥ 400 copies/mL during double blind treatment at Week 24 or any time thereafter have the option of receiving 12 weeks of open-label FTC/TDF which may be continued through the end of the 168-week treatment period if there is a virologic response (HBV DNA < 400 copies/mL). Alternatively, subjects with confirmed HBV DNA < 400 copies/mL at or any time after Week 24 of double-blind treatment may continue blinded therapy up to Week 168 at the discretion of the investigator. If, in the investigator's opinion, it is felt that continued blinded treatment beyond 24 weeks in subjects with confirmed HBV DNA ≥ 400 copies/mL is not beneficial, the subject may discontinue the study and begin commercially available HBV therapy rather than initiate open-label FTC/TDF. |
NCT00371761 ↗ | PegIntron Versus Adefovir in the Treatment of Chronic Hepatitis B (CHB) e Antigen Positive Patients in Taiwan (P04498/MK-4031-278) | Completed | Merck Sharp & Dohme Corp. | Phase 3 | 2006-09-01 | This is an open label, randomized, comparative, multi-center study. Subjects will be screened within 2 weeks prior to study entry to establish eligibility. Subjects who meet all the selection criteria will be randomly assigned 1:1 to (1) once-a-week, subcutaneous Pegylated interferon alfa-2b (PegIntron) (1.5 mcg/kg body weight) or (2) oral adefovir 10 mg daily. The treatment phase will be 24 weeks for PegIntron and 48 weeks for adefovir. All subjects completing the assigned treatment phase will be followed up for an additional 48 weeks for PegIntron and 24 weeks for adefovir as observation phase. The primary objective is to establish the efficacy profile of PegIntron. Secondary objectives are to compare the efficacy profile of PegIntron with that of adefovir, compare efficacy of PegIntron in lamivudine-naïve and lamivudine-experienced subjects, and to establish the safety profile of PegIntron in treating patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B. |
