NCT ID: NCT02233075 Completed - Clinical trials for Chronic HBV Infection (HBeAg Negative)

REP 2139-Ca / Pegasys™ Combination Therapy in Hepatitis B / Hepatitis D Co-infection

Start date: September 2014
Phase: Phase 2
Study type: Interventional

REP 2139-Ca is nucleic acid polymer. Nucleic acid polymers have been previously shown to clear serum hepatitis B virus surface antigen (HBsAg) both preclinically (in duck HBV infected ducks) and in human patients and to act synergistically with immunotherapeutic agents such as pegylated interferon-alpha 2a or thymosin alpha-1 to restore host immunological control of HBV infection. HBsAg is an essential component of the hepatitis D virus (HDV), therefore the direct action of REP 2139-Ca in removing serum HBsAg and its synergistic effect with pegylated interferon-alpha 2a is expected to have a significant antiviral effect against HDV infection. This study will examine the safety and efficacy of REP 2139-Ca therapy when used in combination with pegylated interferon alpha-2a in patients with HBV / HDV co-infection. The primary hypothesis to be tested is that this combined dosing regimen is safe and well tolerated in patients with HBV / HDV co-infection which will be assessed by examining the number of patients with adverse events (including reported symptoms and laboratory abnormalities). The secondary hypothesis to be tested is that this combined dosing regimen will have an antiviral effect against HBV / HDV co-infection in these patients which will be assessed by examining the following outcomes: 1. The number of patients with reductions in serum HBsAg. 2. The number of patients with reductions in serum HDAg and HDV RNA 3. The number of patients that experience a sustained antiviral response after treatment is stopped (reductions in serum HBV DNA and HDV RNA). The secondary hypothesis to be tested is that this combination approach can have an effective

NCT ID: NCT02178592 Completed - HIV Infections Clinical Trials

Open-label Study of Dolutegravir (DTG) or Efavirenz (EFV) for Human Immunodeficiency Virus (HIV) - Tuberculosis (TB) Co-infection

Start date: January 23, 2015
Phase: Phase 3
Study type: Interventional

HIV/Tuberculosis (TB) co-infection have profound effects on the host's immune system. TB is the most common cause of death in patients with HIV worldwide. Rifamycins (such as rifampicin [RIF]) are an important component of TB therapy because of their unique activity. The problem is that most protease inhibitors (PI) and non-nucleoside reverse transcriptase inhibitors (NNRTI) used to treat HIV have significant drug-drug interactions with RIF that can lead to reduced concentrations of these agents with risk of treatment failure or resistance. The non-nucleoside reverse transcriptase inhibitor (NNRTI) efavirenz (EFV) does not present the same significant drug interactions with RIF. EFV-based HIV treatment was tested in patients concomitantly treated with RIF-containing TB therapy, demonstrating that their co-administration can be used safely and effectively. However, the side effect profile of EFV overlaps with the RIF-containing TB regimens and makes the management of treatment toxicities very complex. Integrase inhibitors (INI), such as dolutegravir (DTG), may offer an important alternative to EFV-based therapy in TB coinfected patients. A Phase I drug-drug interaction study was conducted in healthy, HIV-seronegative subjects, and showed that DTG at 50 mg twice daily given together with RIF was well-tolerated and resulted in DTG concentrations similar to those of DTG 50 mg given once daily alone, which is the recommended dose for INI-naive patients. Therefore, ART regimens using DTG 50 mg twice daily may represent a new treatment option for TB-infected patients who require concurrent treatment for HIV infection. This is a Phase III b, randomized, open-label study describing the efficacy and safety of DTG and EFV-containing ART regimens in HIV/TB co-infected patients. This study is designed to assess the antiviral activity of DTG or efavirenz (EFV) ART-containing regimens through 48 weeks. A total of approximately 115 +/-5% subjects will be randomly assigned in a 3:2 ratio to DTG (approximately 69 subjects) and EFV (approximately 46 subjects), respectively. This study will include a Screening Period, a Randomized Phase (Day 1 to 48 weeks plus a 4-week extension), and a DTG Open-label extension (OLE). During the DTG OLE, subjects will be supplied with DTG until it is locally approved and commercially available, the subject no longer derives clinical benefit, or the subject meets a protocol-defined reason for discontinuation, which ever comes first.

NCT ID: NCT02125500 Completed - HIV Clinical Trials

Pilot Study to Assess Efficacy and Safety of Sofosbuvir/Ledipasvir Fixed-dose Combination in Treatment Experienced Subjects With Hepatitis C Virus (HCV) Genotype 1 - HIV Co-infection

Study type: Interventional

Aim of the study is to assess the efficacy and safety of 24 weeks of oral Sofosbuvir/Ledipasvir fixed-dose combination (FDC) in subjects with HCV genotype 1 infection and HIV co-infection, who have previously failed a NS3/4A protease inhibitor plus Pegylated interferon /ribavirin regimen or stopped prematurely their treatment for intolerance.

NCT ID: NCT02109887 Completed - Clinical trials for Non-HIV Patients With Pneumocystis Jiroveci Pneumonia

Assessment of CMV-specific ELISPOT Assay for Predicting CMV Co-infection in Patients With Pneumocystitis Pneumonia (ACE-PCP)

Start date: January 2014
Phase:
Study type: Observational

PCP (Pneumocystis jiroveci pneumonia) is one of the important opportunistic infections in immunocompromised patients including HIV-infected patients, transplant recipients, and immunosuppressant users. About one third of non-HIV patients with PCP have the evidence of co-infection with CMV. In this difficult clinical situation, physicians have difficulty to decide on whether anti-CMV treament will help patients with any evidence of CMV co-infection. However, there is no objective test to differentiate true co-infection of CMV from innocent bystander of CMV in those with PCP. The investigators thus evaluate the usefulness of CMV-specific ELISPOT assay in patients with PCP to differentiate true co-infection of CMV from inocent bystander of CMV. This findings may guide physicians to decide anti-CMV treatment in patients with PCP and CMV co-infection.

NCT ID: NCT01924455 Completed - Hepatitis B Clinical Trials

HBV-HIV Coinfection Research Network

Start date: April 2014
Phase:
Study type: Observational

Despite effective ART that can suppress both HIV and HBV, HBV-related liver disease remains a significant co-morbidity in this population. Little is known about the histologic spectrum of liver disease, the significance of complete vs. incomplete HBV suppression, the utility of novel virologic and serum markers of disease severity, and the long-term renal and bone effects of TDF-based therapy. This proposal will address these important questions and impact the science and health of those coinfected with HBV-HIV.

NCT ID: NCT01900015 Completed - HIV Infection Clinical Trials

Changes in Liver Steatosis After Switching to Raltegravir in HIV/HCV Coinfection

STERAL
Start date: February 3, 2014
Phase: Phase 4
Study type: Interventional

Primary Objective: To compare the impact of switching from efavirenz (EFV) plus two nucleoside analogs to rategravir (RAL) plus two nucleoside analogs versus keeping the same antiretroviral regimen on hepatic steatosis (HS) as measured by the controlled attenuation parameter (CAP) among HIV/HCV-coinfected patient. Secondary Trial Objective: 1. To compare the proportion of HIV/HCV-coinfected patients with one category decrease in the grade of HS between patients continuing with EFV plus two nucleoside analogs and those switching from EFV plus two nucleoside analogs to RAL plus two nucleoside analogs. 2. To evaluate the proportion of patients who maintain viral control (HIV RNA < 50 copies/mL) after switching. Design: Open-label, randomized clinical trial to evaluate safety (phase IV) Condition: HIV and HCV coinfection. Intervention: Patients on current EFV plus two nucleoside analogs will be randomly assigned to switch EFV to RAL (400mg BID), maintaining nucleoside analogs unchanged, or to continue the current regimen.
