Filter by:Study purpose: to explore the entire spectrum of proteomic and genomic changes (amongst others) involved in diseases and in healthy/control populations. The Study is designed to discover biomarkers, develop and validate diagnostic assays, instruments and therapeutics as well as other medical research. Specifically, researchers may analyze proteins, RNA, DNA copy number changes, including large and small (1,000-100,000 kb) scale rearrangements, transcription profiles, epigenetic modifications, sequence variation, and sequence in both diseased tissue and case-matched germline DNA from Subjects.
The goal of this clinical trial is to assess the safety and immunogenicity of a self-replicating (sr) RNA-based vaccine, JCXH-105, in the prevention of Shingles (Herpes Zoster) Participant will be randomized to receive either JCXH-105 or Shingrix.
This is an exploratory study to describe the pharmacokinetics of the azithromycin oral and rectal oleogel in humans compared to the reference oral drug to (Zithromax) assess the impact of the novel formulation on bioavailability. The investigators will perform a randomized, balanced, single dose, three-treatment, three-period, crossover oral bioavailability study under fasted conditions to evaluate the safety and tolerability of azithromycin oleogel and compare the bioavailability of the azithromycin oleogel to the reference drug.
Phase 1b, randomized, open-label, study to evaluate the safety, tolerability, and immunogenicity of RVM-V001 only, RVM-V002 only, or RVM V001 + RVM V002 (Co administered as Separate Injections) in healthy adults. The study will be conducted at one site in Singapore.
Patients referred to internal medicine wards are becoming increasingly complex and fragile. Despite deep knowledge of their specific disorders, steps are required to improve overall management of their acute and chronic conditions. The main objective of the study is to identify demographic, clinical, laboratory and radiological markers of disease severity and activity in patients with diseases treated at general medicine wards (respiratory disease, immune-mediated disease, sepsis, metabolic disease, rare disease, frailty, pregnancy pathology) in order to improve their diagnosis, monitoring and treatment processes.
Nearly half of child deaths occur during the neonatal period, and 80% of those occur in babies with low birthweight. Although tremendous progress has been made towards reducing under-five mortality globally, declines in neonatal mortality lag behind those observed in older children. Low birthweight babies are at increased risk of poor outcomes compared to those who are term-appropriate for gestational age, including mortality, stunting, and growth failure. Recent evidence has demonstrated that the incidence of wasting and linear growth failure is highest between birth and 3 months of age, substantially earlier than previously thought. Interventions are urgently needed to improve outcomes in low birthweight babies; however, these interventions must not interfere with breastfeeding and thus some well-established interventions used to treat or prevent malnutrition in older children cannot be considered. The investigators recently demonstrated that biannual mass azithromycin distribution reduces all-cause childhood mortality by approximately 25% in infants aged 1-5 months, with stronger effects seen in underweight infants. This study did not include neonates due to the risk of infantile hypertrophic pyloric stenosis (IHPS) that has been hypothesized to be associated with macrolide use during early infancy. However, our study team documented only a single case of IHPS among 21,833 neonates enrolled in a trial of azithromycin versus placebo administered to neonates aged 8-27 days for prevention of infant mortality, documenting no major risk of IHPS associated with azithromycin. Here, the investigators propose an individually randomized trial where participants will receive a single oral dose of azithromycin (administered either during the neontal period or 21 days after enrollment), two does of oral azithromycin spaced 21 days apart, or two doses of placebo to evalute if azithromycin improves nutritional outcome and reduces infectious burden among neonates aged 1-27 days who are either low birthweight (<2500 g at birth) or underweight (weight-for-age Z-score < -2 at enrollment). The primary outcome will be weight-for-age Z-score at 6 months of age compared between arms. The investigators anticipate that the results of this study will provide definitive evidence on azithromycin as an early intervention for low birthweight/underweight neonates, who are at the highest risk of adverse outcomes.
The goal of this clinical trial is to learn about, test, and compare JCXH-221 in healthy volunteers. The main aims to answer are: - To assess the safety and tolerability of the JCXH-221 vaccine in healthy adult subjects - To identify an optimal dose for the JCXH-221 vaccine in healthy adult subjects - To assess the humoral immunogenicity of the JCXH-221 vaccine in healthy adult subjects - To characterize the cellular immunogenicity of the JCXH-221 vaccine in healthy adult subjects Participants for Phase I will be randomized to either JCXH-221 or placebo. In Phase 2, participants will be randomized to either JCXH-221 or a FDA approved Active comparator.
The goal of this interventional study is to evaluate the pharmacokinetics, safety, and tolerability of 101-PGC-005 in healthy, adult, human subjects. The main question it aims to answer is what are the single and multi-dose PK properties of 101-PGC-005 in the systemic circulation Participants will receive a bolus injection of 101-PGC-005 administered intravenously once daily for 3 consecutive days. Blood and urine samples will be collected at predetermined timepoints for analysis.
We hypothesize that a high CD4+ and CD8+ T cell count will reduce viremia upon challenge with a structurally heterologous virus, and correspondingly result in reduced magnitude of host response to challenge infection. Primary Objective: To compare, after challenge with a structurally heterologous vaccine, the differences in levels of viremia between healthy adults who received primary vaccination with either YF17D vaccine, chimeric JE-YF17D vaccine, or inactivated JE vaccine. 58 subjects will be randomised into 1 of 2 arms (Arm B1 and Arm B2) in a 1:1 ratio, in a double-blind fashion. Subjects in Arm B1 will receive JE-YF17D vaccine (Imojev, Sanofi Pasteur) on Day 0 followed by YF17D vaccine (Stamaril, Sanofi Pasteur) on Day 28. Subjects in Arm B2 will receive Stamaril on Day 0 followed by Imojev on Day 28. Arm B3 will be conducted as a separate single-arm open label design in 14 subjects. Subjects in Arm B3 will receive inactivated JE vaccine (Ixiaro, Valneva) on Day 0 followed by Stamaril on Day 28. The rationale for these three study arms is as follows: Arm B1 will show the impact low levels of viremia, and the resultant low levels of virus-specific CD4+ and CD8+ T cells, would have on YF17D infection. In contrast, YF17D vaccination in Arm B2 would produce high levels of viremia, and in turn high levels virus-specific T cells, thus likely ameliorating JE-YF17D infection. Arm B3 will serve as the control arm, as vaccination with inactivated JE vaccine would not produce any YF17D-specific T cell response. Notably, the first vaccination in Arms B1 and B2 would also provide the viremia response in the absence of virus-specific T cells, which would serve as a reference point to interpret the outcome of the second vaccination.
