Filter by:The purpose of the study is to characterize the pharmacokinetic (PK) profile of cetrelimab administered subcutaneous (SC) and optionally intravenous (IV) in chronic hepatitis B (CHB) participants.
This is a randomized, double-blinded, placebo-controlled, multi center, dose ranging study of safety and efficacy in volunteers with chronic hepatitis B virus infection. Volunteers will be administered multiple oral doses of ATI-2173 vebicorvir in combination with tenofovir disoproxil fumarate and assessed for safety and efficacy including blood tests to show how the body metabolizes and eliminates the investigational drug as well as how the drug effects the virus infection.
Patients with medical conditions requiring allogeneic hematopoietic cell transplantation (allo-HCT) are at risk of developing a condition called graft versus host disease (GvHD) which carries a high morbidity and mortality. This is a phase I/II study that will test the safety and efficacy of hematopoietic cell transplantation (HCT) with ex-vivo T cell receptor Alpha/Beta+ and CD19 depletion to treat patients' underlying condition. This process is expected to substantially decrease the risk of GvHD thus allowing for the elimination of immunosuppressive therapy post-transplant. The study will use blood stem/progenitor cells collected from the peripheral blood of parent or other half-matched (haploidentical) family member donor. The procedure will be performed using CliniMACS® TCRα/β-Biotin System which is considered investigational.
Background: CT has been used on a massive scale to help identify and investigate suspected or confirmed cases of COVID-19 pneumonia. This study aimed to assess the prognostic significance of the chest findings MSCT of Covid-19 patients and to determine if prognosis can rely on the initial CT imaging. Methods: The study design was retrospective cohort study. It was carried out on 300 patients presented to the chest outpatient clinics in Benha university hospitals and Elabbasyia chest hospital with clinical picture suggestive of COVID 19 infection. The CT finding were then compared to the short-term clinical outcome of the patients (1-3weeks), acquired from the hospital patient data archive. According to the progression of the respiratory symptoms (include; dyspnea, respiratory rate and O2 saturation), the short-term clinical outcome of the patients was classified into 4 groups; Group A: (mild cases), Group B: (moderate cases), Group C: (sever cases), and Group D: (fatality cases).
Pertussis is a bacterial respiratory infection caused by Bordetella pertussis. Highly contagious, it is potentially serious and even fatal in infants under 6 months of age. The immunity acquired through vaccination is very limited in time, requiring regular booster shots. There is a passive protection of the newborn by the maternal-fetal transmission of maternal antibodies, but it is brief. The infant's first vaccination is given at 2 months of age and immunity is not acquired until the second injection at 4 months of age. The booster at 11 months of age is essential to prolong this immunity. In order to protect infants under 6 months of age, France has recommended since 2004 the cocooning strategy, which consists of vaccinating people likely to be in close contact with the infant during this period. This vaccination is therefore proposed to adults who are planning to have children, to the entourage of pregnant women, and in the immediate post-partum period for the mother (and people who were not vaccinated during pregnancy). This strategy was put in place following the international recommendation of a forum of scientific experts, the Global Pertussis Initiative. In France, vaccination against pertussis is not currently recommended during pregnancy. There is no contraindication to vaccination during pregnancy and it is recommended in many countries. Influenza is a viral respiratory infection caused by Myxovirus influenzae, which is highly contagious. In France, vaccination against influenza is recommended for pregnant women, regardless of the trimester of pregnancy. It is also recommended for the entourage of infants under 6 months of age with risk factors for severe influenza. There are few recent data in the scientific literature regarding influenza and pertussis vaccination coverage among pregnant or postpartum women in France. In addition, the COVID19 pandemic has recently reopened the debate on vaccination of the general population and caregivers. Knowing the current status of vaccination coverage among pregnant women and caregivers, their knowledge and fears regarding vaccination could help improve the information provided by healthcare staff.
Open label, single arm, multi-center clinical trial of lonafarnib 50 mg QD plus ritonavir 200 mg QD, administered orally, over a 48-week treatment period, with a 24-week post-treatment follow-up period, in patients with chronic Hepatitis D Virusinfection. Objectives: To evaluate the safety and tolerability of once daily dosing of lonafarnib 50 mg with ritonavir 200 mg over a 48-week treatment period. To evaluate the effect of once daily dosing of lonafarnib 50 mg with ritonavir 200 mg over a 48-week treatment period with a 24-week post-treatment follow-up on HDV viral levels. Trial population: Up to 30 patients with chronic HDV infection with detectable HDV RNA and compensated liver disease.
This study seeks to identify and test host RNA expression profiles in context to protein biomarkers in dried blood spot samples as novel diagnostic markers of neonatal herpes simplex virus infection and to improve the understanding of the pathogenesis of the disease.
Patients are frequently evaluated by physicians for medical work-up of HIV indicator conditions in hospital and in primary care at the general practitioner. Testing for HIV is indicated with HIV indicator disorder but often omitted in clinical work-up. Besides the fact that HIV testing is forgotten, there are other reasons such as an underestimation of the risk of HIV in the event of indicator disorders, stigma and difficulties in discussing the test with a patient. Also and more relevant for primary care than for the hospital, practical challenges can exist for a patient to go to a laboratory, or costs are a hurdle. This project focuses on improving HIV indicator condition driven testing in different settings of the HIV epidemic, initially in the Netherlands as low HIV prevalence setting followed by an assessment of its benefit in different international settings. A specific focus will also be on the Rotterdam area in the Netherlands which has a high prevalence of undiagnosed HIV in the Netherlands. The ultimate aim is to decrease the number of undiagnosed HIV in populations, improve the 90-90-90 HIV cascade of care goals particularly its first pillar, and to help supporting the UNAIDS goal to end HIV/AIDS
The main objective of the clinical study is to evaluate the efficacy of Zinc supplementation in non-critically ill Covid-19 patients..
Ebola virus disease (EVD) is emerging regularly in various African countries for various reasons: during contact with mortal remains, during an unsafe burial or following the viral dissemination around a recovered patient. However, tools to fight the spread of the disease are being made available to countries affected by MVE. A vaccine (Ervebo), developed by the Merck laboratory, demonstrated its efficacy in protecting contacts and contacts of contacts in the "Ebola That's Enough" trial and two monoclonal antibodies (Mabs) have demonstrated their efficacy in reducing mortality in patients with EVM: REGN-E3B and Mab114. The question of their use in post-exposure prophylaxis (PEP), defined as the treatment of contacts at very high risk of contracting EVD, is essential. Vaccination with Ervebo alone does not appear to be a good option for PEP, particularly because antibody synthesis is delayed, and the vaccine is likely to be inactive for 10 days after administration. Monoclonal antibodies, on the other hand, seem to be a promising avenue in this indication because of their rapid action on the inhibition of virus entry into the cell. Moreover, Ervebo vaccine and monoclonal antibodies share the same viral target. It is therefore possible that the vaccine is inhibited by the monoclonal antibodies, particularly in the case of concomitant administration. However, no data on vaccine efficacy in combination are available. The question of the interaction between the monoclonal antibody and Ervebo and the delay between the administration of these two strategies remains unresolved. The hypothesis of this trial is that Ervebo vaccine efficacy is diminished with the concomitant administration of a monoclonal antibody, especially if this administration is close (short time between Mabs and vaccination). We hypothesize that with an optimal delay between Mabs and vaccination, the immunogenicity of the vaccine combined with monoclonal antibodies could be non-inferior to the vaccine alone, thus providing optimal short and long term protection. The primary objective of this study is to compare the vaccine immune response at 24 weeks induced by Ervebo administered on the same day (D0) or at S3, S6, or S12 of Inmazeb administration, in healthy volunteers, with vaccination with Ervebo alone. The trial will have 5 arms. The control arm (vaccination alone) will serve as a comparator of vaccine response in the intervention arms. The 4 intervention arms will assess the minimum time between Mab and vaccination.
