NCT ID: NCT01205165 Completed - Clinical trials for Hepatitis B, Chronic

An Open Label, Multi Centre Phase IV Study of Adefovir Dipivoxil in Korean Patients With Chronic Hepatitis B (CHB)

Start date: December 17, 2004
Phase: Phase 4
Study type: Interventional

Objective(s) The primary study objective is to assess the antiviral effect of 12 weeks of adefovir dipivoxil treatment in Korean patients with chronic hepatitis B and compensated liver disease. The secondary study objectives are to assess the antiviral effect, clinical benefit and safety of 52 weeks of adefovir dipivoxil treatment. Endpoint(s) The primary efficacy endpoint is "Mean log10 reduction in serum HBV DNA level from baseline to Week 12". The secondary efficacy endpoints include (a) the proportion of patients achieving serum ALT normalization at Week 52, (b) other assessments of antiviral effects (the proportion of patients achieving HBV DNA no less than 300 copies per mL at Week 52), (c)HBeAg loss, HBeAg seroconversion, HBsAg loss and HBsAg seroconversion, (d)the proportion of patients achieving serum ALT normalization at Week 12. Study Design This is an open label, multi centre phase IV study for Korean patients with chronic hepatitis B and compensated liver disease, assessing the antiviral effect of 12 weeks treatment of Adefovir dipivoxil as a primary objective and antiviral effect, clinical benefit and safety of 52 weeks treatment as secondary objectives. Patients will be screened for eligibility criteria and the baseline visit for the treatment initiation should occur no more than 4 weeks after screening. Total treatment period will be 52 weeks and patients will return to the clinic for assessments as scheduled during treatment period. After the 52 week study period, it is likely that the patient will benefit from continued treatment with commercial adefovir. If in the investigator's clinical judgement this is the case, the investigator should ensure that a routine prescription is available in a timely manner, and that no unnecessary interruption in treatment occurs. Study Population A minimum of 100 male or female Korean patients more than 18 years of age with HBeAg positive chronic hepatitis B and compensated liver disease who meet the eligibility criteria will be enrolled. Study Assessments and Procedures Potential patients will be screened prior to study entry and eligible patients who have given their consent will have further baseline assessments. Following the screening, the first doses of study medications will be given at baseline and patients will return to the clinic for assessment as scheduled during treatment period. Patients who discontinue treatment prematurely will be followed up every 4 weeks for 12 weeks following the withdrawal visit. The following key assessment and or measurement will be made at one or more visits during the study. (See section 14.1 Appendix 1. Time and event schedule): - Pregnancy test (females of child-bearing potential only) - Haematology and serum chemistry profile including prothrombin time(PT) and AFP - HBV DNA (Roche COBAS AMPLICOR HBV MONITOR Test, LLOD 300 copies per ml) - Hepatitis B markers: HBeAg(Anti HBe will be tested if HBeAg is negative), HBsAg(Anti HBs will be tested if HBsAg is negative) Investigational Product(s) Adefovir dipivoxil 10mg tablets will be supplied by GlaxoSmithKline and presented as a white to off white, round tablets, packaged in the bottle containing 30 tablets

NCT ID: NCT01204827 Withdrawn - Chronic Hepatitis B Clinical Trials

Follow Up of Patients Chronic Hepatitis B (CHB) Treated With Sebivo Using the 13C Methacetin Breath Test

Start date: n/a
Phase: Phase 2/Phase 3
Study type: Interventional

Patients with HBeAg negative chronic HBV and evidence of hepatic disease (elevated liver enzymes or evidence of cirrhosis) who have significant viremia are treated with anti HBV therapy. Currently the key goals of anti HBV therapy are profound and prolonged viral suppression and treatment efficacy is assessed by monitoring viral load and liver enzymes. However these do not always reflect the degree of liver impairment or the degree of improvement in response to therapy. Sebivo has been accepted in Israel as a first line therapy for HBeAg negative and HBeAg positive chronic HBV with evidence of liver damage. Viral load should decrease by 1 log every 3 months, otherwise patients should be offered add-on or alternative therapy. As the majority of patients in Israel are HBeAg negative chronic HBV and in order to have homogenous population we will select for our study only patients with HBeAg negative chronic HBV. The 13C Methacetin breath test, assess liver function and specifically the function of the microsomal CYP4501A2. It has been shown to correlate with the degree of liver impairment and with clinical outcomes in both acute and chronic liver disease. The aim of this study is to determine the utility of the 13C Methacetin Breath Test to follow up patients with HBeAg negative chronic HBV receiving anti viral therapy.

NCT ID: NCT01199601 Completed - Contraception Clinical Trials

Blood-borne Infection Screening in an Afghan Antenatal Population

Start date: June 2008
Phase: N/A
Study type: Interventional

Baseline information indicates there are measurable levels of hepatitis B SAg and low utilization of postpartum contraception, correct breastfeeding practices, or adherence to infant vaccination schedules in Kabul, Afghanistan. This intervention will randomize hospitals to assess the following aims: Aim 1: To determine whether the re-training and assignment of health care providers dedicated to intrapartum rapid testing and post-partum counseling will positively impact maternal and neonatal health indicators as compared to utilization of existing health providers for these services among women delivering in publish health maternity hospitals in Kabul, Afghanistan. Aim 2: To assess whether patients randomized to the intervention and their spouses perceive value in concentrated post-partum counseling. Aim 3: To investigate whether an intervention providing immediate post-partum provision of a long-acting family planning method would be feasible and acceptable to both men and women in Kabul, Afghanistan. Outcomes will be assessed through questionnaire responses and inspection of vaccination cards at six month intervals by trained study staff. The third aim will be addressed at the 12 month follow-up visit.
