NCT07134751
Approximately one million febrile infants aged ≤60 days present annually to pediatric emergency departments (PEDs) in Europe and the United States. Although fewer than 5% are diagnosed with meningitis or bacteremia (invasive bacterial infections - IBIs), and 10-15% with urinary tract infections (UTIs), current guidelines recommend extensive diagnostic evaluations, hospitalization, and empirical treatment with broad-spectrum parenteral antibiotics. This approach may contribute to medical overuse, with implications for patient care, healthcare resource utilization, and environmental sustainability. The Febrile Infants Swedish Study (FISS) is a prospective observational study conducted across 11 PEDs in Sweden. All febrile infants aged ≤60 days presenting to participating sites will be eligible. A new clinical guideline for the management of infants with fever without source (FWS) will be implemented in 7 PEDs, while 4 PEDs will continue with current standard practice and serve as a comparison group. The study is expected to run for approximately two years and aims to recruit a minimum of 2,500 febrile infants
NCT07505836
The goal of this clinical trial is to evaluate the immunogenicity and safety of an investigational group ACYW135 Meningococcal conjugate vaccine in healthy children aged 12 to 23 months. The main questions it aims to answer are: Is the immune response induced by the investigational vaccine non-inferior to that of the licensed control vaccine? What safety profile does the investigational vaccine have in this pediatric population? Researchers will compare the investigational vaccine group with the active comparator group (licensed ACYW135 meningococcal conjugate vaccine (CRM197 carrier), CanSinoBIO; hereinafter referred to as CanSinoBIO MCV-ACYW) to determine if the new vaccine provides comparable immune protection with an acceptable safety profile. Participants will: Receive two doses of either the investigational vaccine or the control vaccine according to a 0,1-month schedule; Be observed for 30 minutes after each dose for immediate adverse reactions; Have solicited local and systemic adverse events recorded for 7 days after each dose using diary cards; Have unsolicited adverse events recorded for 30 days after each dose using diary cards; Be monitored for serious adverse events for at least 6 months after completion of the primary immunization series; A total of 1040 participants will be enrolled and randomly assigned in a 1:1 ratio to either the investigational group or the control group.
NCT07505823
The goal of this clinical trial is to evaluate the immunogenicity, safety, and persistence of the immune response of a group ACYW135 meningococcal conjugate vaccine in healthy children aged 6 to 11 months. The main questions it aims to answer are: Is the immune response induced by the investigational vaccine non-inferior to that of the licensed control vaccine following the primary series? What is the safety profile of the investigational vaccine during the primary series and booster dose? Does the investigational vaccine provide durable immune persistence up to 18 months of age? What is the immunogenicity of a booster dose administered at 18 months of age? Researchers will compare the investigational vaccine group with the active comparator group (licensed group ACYW135 meningococcal conjugate vaccine (CRM197 carrier), CanSinoBIO) during the primary immunization phase. Only the investigational group will receive a booster dose at 18 months of age to evaluate booster immunogenicity and safety. Participants will: Be randomly assigned in a 1:1 ratio to receive either two doses of the investigational vaccine or two doses of the control vaccine according to a 0,1-month schedule during the primary immunization phase; In the investigational group only, receive a booster dose at 18 months of age; Provide blood samples at three time points: before primary vaccination, 30 days after primary vaccination, and at 18 months of age to assess primary immunogenicity and immune persistence; In the investigational group only, provide an additional blood sample 30 days after the booster dose to assess booster immunogenicity; Be observed for 30 minutes after each dose for immediate adverse reactions; Have solicited local and systemic adverse events recorded for 7 days after each dose using diary cards; Have unsolicited adverse events recorded for 30 days after each dose using diary cards; Be monitored for serious adverse events for at least 6 months after the last dose administered; A total of 1040 participants will be enrolled.
NCT05093829
Infants aged 9 months will be randomized to receive a meningococcal vaccine at 9 months or 15 months. Infants randomized to the 9-month age group will be further randomized in a 2:1 ratio to receive a single dose of the experimental meningococcal vaccine (NmCV-5) or a single dose of the comparator meningococcal vaccine (MenACWY-TT). Prospectively identified and consented infants randomized to the 15-month age group will return when aged 15 months and will be randomized in a 2:1 ratio to receive a single dose of NmCV-5 or a single dose of MenACWY-TT.

Who is suitable to participate? Parents/legal guardians of all children aged between 1day to 12 years, who are suspected to have brain infection (meningitis) attending the Pediatric emergency room at the Royal Hospital. Participants will: Be counseled using verbal snd video method = Intervention group OR verbal method only = Control group The Researchers will collect the acceptance rate in performing LP in both groups.
NCT03549325
This study is part of a project that aims to develop a vaccine with N. lactamica that prevents meningitis. The investigators have previously given nose drops containing N. lactamica to over 340 volunteers, and shown that many of the volunteers (35-60%) become colonised without causing any illness or disease. In the future the investigators would like to modify N. lactamica so that it can carry vaccine molecules into the nose of children. To do this the investigators need to know more about the immune response generated against N. lactamica. Previously the investigators have shown that inoculation resulted in an immune (antibody) response in volunteers who were colonised. Taking an antibiotic called ciprofloxacin will treat N.lactamica in the nose and throat of the volunteers. The investigators need to know if the immune response to N. lactamica is the same when colonised volunteers are treated with the antibiotic after 4 days, is the same if the investigators treat volunteers after 14 days of carriage. This information will inform future studies.
NCT06666322
Cryptococcal meningitis is a fungal infection that causes a severe syndrome of meningitis that is 100% fatal without antifungal therapy. Even with antifungal therapy, mortality rates remain high, especially in low and middle income countries where the ongoing HIV/AIDS pandemic increases the risk of cryptococcosis among persons living with HIV infection. The combination of amphotericin and flucytosine (5-FC) has been the mainstay of therapy for the initial management of cryptococcal meningitis for 4 decades. Indeed, the effective delivery of these first line therapy in Africa can lower mortality to 25%. However, several challenges exist. First, even while 5-FC is included on the WHO list of essential medicines, the availability of 5-FC worldwide is limited. Second, liposomal amphotericin (Ambisome ®) is currently available from a single source supplier, creating risk. Third, current therapies have substantial toxicity. Lastly, with widespread agricultural fungicide use of azoles, the median fluconazole minimum inhibitory concentration (MIC50 ) for Cryptococcus has doubled since 2013. Globally, new or improved antifungals are needed for cryptococcal meningitis, particularly those which have less toxicity, greater efficacy, a prolonged half-life, and minimal drug-drug interactions. As multiple new antifungal medicines are on the horizon, this platform trial utilizes a master protocol to investigate, multiple regimens using standardized eligibility criteria, standardized study schedule of events, and standardized contemporary endpoints.

NCT05452928
To determine whether active treatment with (val)acyclovir is superior for treatment of viral meningitis compared with placebo assessed by numbers meeting a primary, objective endpoint at 7 days after randomisation
NCT02102256
Current treatment options for bilateral profoundly deaf children, diagnosed with inner ear anatomical abnormalities, are limited and, in the case of absent cochleas, non-existent. An auditory brainstem implant (ABI) places an electrode close to the auditory nucleus in the brainstem. Children aged 2 - 5 who are not candidates for a cochlear implant, or who did not demonstrate benefit from a cochlear implant, will be implanted with an ABI and followed for 1 year for safety and a total of 3 years for preliminary efficacy. This is a feasibility study to determine the safety of the ABI.
NCT03100786
The primary objective is to determine whether Leukotriene A4 hydrolase (LTA4H) genotype, defined at randomisation, determines dexamethasone's clinical effectiveness when added to the first 6-8 weeks of anti-tuberculosis treatment of TBM. The investigators will conduct a LTA4H genotype stratified, parallel group, randomised, double blind, placebo-controlled multi-centre Phase III non-inferiority trial evaluating dexamethasone versus placebo for 6-8 weeks in addition to standard anti-tuberculosis drugs. The investigators will take a hybrid trial-design approach which assumes a modest harm of dexamethasone and aims to prove non-inferiority of placebo first but also allows claiming superiority of placebo in case dexamethasone causes substantial harm. Moreover, as it is possible that harm of dexamethasone only applies to the LTA4H CC genotype, the trial will allow dropping the CT group at an interim analysis but continue randomization of the CC group. In making this assessment the investigators not only determine whether dexamethasone influences survival and the incidence of new neurological events (the primary endpoint), but also whether it influences disability assessed by the modified Rankin score 12 months after the start of treatment. The secondary objective is to investigate alternative management strategies in a subset of patients who develop drug-induced liver injury that will enable the safe continuation of rifampicin and isoniazid therapy whenever possible.
NCT04886154
The purpose of this study was to assess the safety, effectiveness, and immune response of the meningococcal combined ABCWY vaccine (GSK4023393A) intended to protect against invasive meningococcal disease (IMD) caused by all 5 meningococcal serogroups. The first time-in-human (FTIH), Phase I part of this study was conducted in healthy adults in a dose-escalating fashion with 2 formulations of the investigational MenABCWY-2Gen vaccine and served as a safety lead-in to the Phase II study. The Phase II part of the study was conducted in 2 parts: The 'formulation and schedule-finding' part followed in healthy adolescents and young adults and was designed to select the vaccine formulation and the schedule to be tested in Phase III. The 'blood sourcing' part was conducted in healthy adults in order to collect sufficient serum samples for the development of assays to be used in the MenABCWY-2Gen vaccine clinical development program.
NCT03295318
Out of the 13 identified serogroups of Neisseria meningitidis (Nm) the six serogroups (A, B, C, W, Y and X) are responsible for majority of infections. Presently available vaccines effectively protect against A, B, C, W and Y serogroups; but no vaccine that is protective against serogroup X is available yet. Serum Institute of India Private Limited (SIIPL) has developed a conjugate vaccine against serogroups A, C, Y, W and X (NmCV-5). The first-in-human Phase 1 study was among 60 healthy adults in USA did not show no any safety issues. This phase 2 study is designed to evaluate safety and immunogenicity of the non-adjuvanted and adjuvanted formulations of NmCV-5 in healthy children 12-16 months of age, in comparison with the licensed quadrivalent meningococcal conjugate vaccine (Menactra®). Both vaccines will be administered in two dose schedule 3 months apart. among vaccine-naïve healthy subjects in Mali. Safety will be assessed by collecting solicited reactions till day 7 post each dose whereas adverse events will be collected throughout the study. Each subject will be followed up for 84 days post each vaccine dose. The vaccine immunogenicity will measured using a rabbit complement serum bactericidal activity assay (rSBA).
NCT06465420
Haemophilus influenzae serotype a (Hia) has emerged as a leading cause of serious illness in Indigenous children in Canada and Alaska in recent decades. In hospital-based surveillance studies, Hia was the most common cause of invasive disease, resulting in morbidity or mortality after Haemophilus influenzae serotype b (Hib). Given the success of the Hib vaccine program and the pathophysiologic similarities between Hib and Hia, immunization is the obvious way to protect Indigenous children living in small and scattered communities. The Public Health Agency of Canada has been working with the National Research Council and other members of the Consortium, including the Canadian Immunization Research Network, McGill Interdisciplinary Initiative in Infection and Immunity, GlycoNet, the Hewitt Foundation, and Inventprise/InventVacc, to develop a Hia vaccine for prevention of this deadly infection. The engagement process initiated by NRC with Consortium members and representatives from Indigenous groups, particularly, has led to the current project plan. In this first-in-human study, the investigators propose investigating the safety and immunogenicity of a novel glycoconjugate candidate vaccine that uses protein carrier CRM197 in healthy adults in the general population. The study will be conducted at the McGill University Health Center Vaccine Study Centre in Montreal and the Canadian Center for Vaccinology in Halifax. The findings of this Phase I study will be necessary to effectively move this potential vaccine solution further along the development continuum.
