Filter by:This is a single center Phase I clinical trial of FT538 administered intravenously (IV) once every 14 days for 4 consecutive doses for the reduction of the HIV reservoir in lymphoid tissue of HIV-infected individuals receiving standard of care (SOC) antiretroviral therapy (ART). As this is an early 1st in human study and the 1st for HIV-infected individual, the safety of FT538 is confirmed prior to the addition of oral vorinostat to explore the concept of "Kick and Kill".
Uganda uses a threshold of 1,000 copies/ml to determine HIV viral non-suppression among people living with HIV/AIDS (PLHIV) on treatment, which is indicative of either poor adherence or HIV virologic treatment failure; as per the recent WHO recommendations. The use of this high threshold of 1,000 copies/ml has resulted into an increase in the number of PLHIV having low-level viraemia (≥50 to <1,000 copies/ml) from 11.0% in 2017 to 35.0% in 2020 in Uganda. Different studies in developed countries have shown that low-level viraemia is associated with HIV drug resistance, and despite this, there is no intervention to manage and control low-level viraemia (LLV), as per the recent Uganda national HIV guidelines. With this increasing and unmanaged low-level viraemia (LLV), Uganda might never achieve the global targets of ending AIDS as epidemic by 2030, as stipulated by target 3.3 of SDG 3. This study will therefore determine the effectiveness of intensive adherence counselling on achieving a non-detectable viral load (below 50 copies/ml) in the management of LLV among PLHIV on ART in Uganda. This study will generate useful information that might guide the review of the national HIV guidelines, to control and manage LLV among PLHIV on ART; and thereby enable Uganda to achieve the global goals of SDG 3, Target 3.3 and the national targets of Vision 2040.
This is a Phase II, multicenter, open-label, randomized, standard of care (SOC) controlled, multiple ascending dose study to assess the safety and tolerability of IV Brincidofovir (BCV) in subjects with BKV infection after kidney transplantation. The study will be conducted at multiple study sites in several countries including Australia and Japan. Subjects who meet eligibility criteria will be enrolled in the study and will be randomized and assigned to BCV or SOC (defined as use of the same immunosuppressant administered during prescreening) before receipt of the first dose of study drug in both the Dose Escalation Phase and the Expansion Phase.
CMV infection is the most prevalent infection after heart transplantation (HTX), occurring in up to 40-60% of the recipients. It most frequently occurs within the first 6 months after transplantation and commonly presents as an asymptomatic viral replication. Viral syndrome or tissue-invasive disease (gastroenteritis, pneumonitis, myocarditis or meningitis) are much less common. Even though CMV infection is generally treatable with virostatic therapy and/or CMV-specific immunoglobulins, direct effects of CMV infection (viral syndrome and tissue-invasive disease) and general and transplant-specific indirect effects of CMV infection have been associated with significant morbidity and mortality in HTX patient population, mainly due to graft loss, development of malignancies, or opportunistic infections. According to the latest consensus paper on CMV prophylaxis and treatment in solid organ transplant recipients, valgancyclovir (or its active form gancyclovir) represents a virostatic therapy of choice for CMV prophylaxis and treatment after HTX. However, valgancyclovir has an array of side effects including hematological (leukopenia, neutropenia, anemia, thrombocytopenia), neurologic (headache, insomnia), gastrointestinal (decreased appetite, diarrhea, vomiting and dyspepsia) and psychiatric (depression) disorders. These can either expose HTX patients to additional complications (e.g. leukopenia and/or neutropenia can result in systemic fungal infections), decrease patients' quality of life, or mandate a decrease in valgancyclovir dose, which exposes patients to an increased risk for CMV reactivation. Recently, letermovir (a novel CMV viral terminase inhibitor), was approved for CMV prophylaxis in allogeneic bone marrow transplant recipients as the placebo-controlled study showed that significantly less patients, treated with letermovir, developed CMV disease (37% vs. 60%; P<0.001) and there was also a trend towards lower all-cause mortality. Data on bone marrow transplant recipients additionally suggest that letermovir is generally well tolerated with side effects limited to mild gastrointestinal symptoms (diarrhea, nausea). Importantly, myelosuppresive side effects of letermovir occur very rarely. Some encouraging data does exist on the use of letermovir in kidney transplant recipients, where a recently published proof-of-concept trial (N=27) suggested comparable safety and efficacy of leteremovir (N=18) and valgancyclovir (N=9): both treatment regimens resulted in similar time-course of viral load reduction and viral clearance and were well tolerated in terms of adverse events. Currently, a Phase III clinical trial is ongoing in renal transplant recipients (Clinicaltrials.gov: NCT03443869) to confirm this pilot data. However, to date, there is no published data on the use of letermovir in patients after HTX. Based on the results in kidney transplantation, the aim of this pilot study is thus to evaluate the effects of letermovir-based CMV prophylaxis in heart transplant recipients. The primary objective of the study is to investigate the efficacy of letermovir-based CMV prophylaxis in patients after heart transplantation. The secondary objectives of the study are: - to investigate the tolerability of letermovir-based CMV prophylaxis in patients after heart transplantation. - to explore the potential correlation between letermovir-based CMV prophylaxis and restitution of cell-regulated immunity in patients after heart transplantation.
The study will test four behavioral intervention components to identify the combination of the four components that best supports people who inject drugs to achieve and sustain HIV viral load suppression. The study design is a 2-to-the-4 factorial experiment. The 2 represents the level of each component: 0 (receive) or 1 (don't receive). The 4 represents the number of components being tested. The four components are: 1) receiving (or not receiving) peer support services for medication-assisted treatment (MAT) uptake and persistence, 2) behavioral activation therapy for depression (BAT), 3) Life-Steps Program for medication adherence, and 4) patient navigation for HIV care. Therefore, in order to test which combination of components produce the best outcome, this factorial design randomizes people to 1 of 16 conditions. Each condition represents a possible combination of the 4 components above.
BEAT-BK will see the effect of immunosuppression reduction/modification with and without IVIG on BKPyV infection, allograft function, allograft loss, acute transplant rejection, immunosuppression load and death in kidney and simultaneous kidney pancreas transplant recipients with polyomavirus infections (BKPyV).
The human BK polyomavirus is a significant risk factor for renal transplant dysfunction and allograft loss. The prevalence of BK viremia (BKV) following kidney transplantation is estimated to be 10-20%.
To date, antiviral treatment is not recommended for chronic hepatitis B patients with a normal ALT level and low viremia. The strategy is to closely monitor the patients. However, evidence suggests that these group are at risk of gradual disease progression and development of hepatocellular carcinoma. Peginterferon eliminates the hepatitis B virus through immune regulation and induction of antiviral protein expression. For patients with low viral load, the clinical cure rate is potentially promising. In this study, we aim to investigate the efficacy and safety of peginterferon alpha-2b therapy in selected chronic hepatitis B patients with normal ALT level and low viremia. It is expected to obtain a satisfactory curative effect. Peginterferon is a marketed drug available in Chinese clinics with indications of anti-hepatitis B virus.
Reduction of BK Viremia by treating kidney transplant patients.
Beyond EV-B, there are clinical observations to implicate other viruses in birth defects, including CHD. Since the Rubella epidemic of 1960s', however, viruses have received little attention and certainly no comprehensive study, especially using next generation sequencing (NGS), has been undertaken in this context. The current pandemic as well as those caused by Zika, influenza, Ebola and Lassa Fever (among many) have shown pregnant women and their baby are at high risk. Therefore, an open-minded approach is warranted when considering the role of maternal viral infections in CHD. Even less is known about maternal immune response, such as antibody production, to these viruses. The investigator's goal is to answer the above gaps in knowledge. The investigators propose to do that using two different approaches; one retrospective (analysis of samples in two existing, large biorepositories) and the other prospective. The investigator's have created a multi-disciplinary team to bring together the needed expertise from individuals who have overlapping and vested interest in this project. The investigator's specific aim is to examine the diversity of the gut virome in non-pregnant and pregnant women with and without diabetes, with special emphasis on known cardiotropic viruses (those with tropism for cardiac tissues). This study is seen by the investigator's as the first step prior to a larger prospective multi-institutional study to specifically assess the linkage between the maternal virome and CHD pathogenesis.
