Adefovir 10mg tablets

BackgroundChronic hepatitis B (CHB) affects a vast population globally. A variety of drugs are available for the treatment of CHB, including tenofovir (TDF) and adefovir (ADV). However, the efficacy of monotherapy drug treatment is inconclusive, the safety and efficacy of TDF remain unclear, more data are needed to be included and combined drug treatment is considered to exhibit higher efficacy. To explore this issue, we performed a current literature review and meta-analysis to compare the efficacy and safety of ADV vs. TDF, TDF vs. ADV + lamivudine (LAM); TDF vs. ADV + entecavir (ETV).MethodsWe systematically searched China National Knowledge Infrastructure, the Cochrane Library, Embase, PubMed, Chinese VIP, and Wanfang Data, for relevant clinical trials since July 2015, all included studies were based on PICOS principles and evaluated independently by the reviewers in accordance with the Cochrane Handbook (Rob2.0). A meta-analysis was performed by using Review Manager 5.4.ResultsWe included a total of 32 studies, including 31 randomized controlled trials and one retrospective study involving 2,473 patients. The results revealed a low risk of bias in included studies, that the virologic response of TDF was superior to ADV (PConclusionsResults showed that TDF was superior to ADV in the parameters of ALT, hepatitis B virus (HBV)-DNA reduction, HBeAg-negative conversion rate, safety, and total bilirubin levels in patients with CHB. However, when ADV was combined with LAM or ETV, they often showed the same therapeutic effect as TDF in parameters such as ALT level and Tbil level and combined therapy can effectively reduce the occurrence of adverse reactions. In this study, because the sample source countries were limited, a greater number of global studies are needed in the future to verify the current findings.

Background and aimsPradefovir mesylate is a novel liver-targeting prodrug of adefovir developed using HepDirect technology. We report that the phase 3 trial is to compare the efficacy and safety of pradefovir versus tenofovir disoproxil fumarate (TDF) in patients with chronic hepatitis B (CHB).Approach and resultsThis ongoing randomized, double-blind, non-inferiority, phase 3 study was conducted at 58 sites in China. Patients with CHB were randomly assigned (2:1) to receive either 45 mg daily pradefovir or 300 mg daily TDF with a matching placebo. The primary efficacy endpoint was defined as the proportion of patients whose HBV DNA level was ConclusionsPradefovir should be a highly recommended treatment option for adult patients with CHB.
