NCT ID: NCT05831124 Active, not recruiting - Clinical trials for Pneumococcal Disease

A Study to Learn About a Type of Pneumococcal Vaccine With a New Ingredient (PF-07872411) Intended to Enhance the Effects of the Vaccine Which is Given to Adults

Start date: April 19, 2023
Phase: Phase 1
Study type: Interventional

The purpose of this clinical trial is to learn about a pneumococcal vaccine with a new ingredient (PF-07872411) intended to enhance the effects of the vaccine. This pneumococcal vaccine with the new ingredient may prevent the diseases caused by pneumococcal bacteria like meningitis, sepsis, ear infections and sinusitis. Meningitis is an infection in which the tissue around the brain and spine is swollen. Sepsis is a very serious infection in your blood caused by a germ (a bacteria). Sinusitis is when your sinuses (the air-filled spaces inside your nose and head), are infected. This study is seeking for healthy participants who: - are above 50 years of age and less than 64 years of age. - have not taken any vaccine for pneumococcal diseases before. - have not taken any vaccines with additional ingredients within 1 year before administration of the study vaccine. All participants will receive a single study vaccine shot in the upper arm muscle at the study clinic. The study will compare the experiences of people receiving the vaccine with a new ingredient in the vaccine to those without the new ingredient. This will be done by comparing 2 different dose levels of the new ingredient. It will also be compared against people who receive the vaccine without the new ingredient and at different dose levels. This will help the study team establish if the vaccine with a new ingredient is safe and effective. Participants will take part in this study for about 12 months. During this time participants will have up to 6 clinic visits. At these clinic visits, participants will be asked if any side effects were experienced. The participants will also have to give blood samples during these visits. Some participants will need to have blood taken for laboratory tests before they can be judged to be eligible to be included in the study.

NCT ID: NCT05569954 Active, not recruiting - Clinical trials for Pneumococcal Disease

Safety and Immunogenicity of V116 in Pneumococcal Vaccine-naïve Adults 50 Years of Age or Older (V116-010, STRIDE-10)

Start date: November 7, 2022
Phase: Phase 3
Study type: Interventional

This is a phase 3, randomized, double-blind, active comparator-controlled study of the safety, tolerability, and immunogenicity of V116 in pneumococcal vaccine-naïve adults 50 years of age and older. The polyvalent (23-valent) pneumococcal vaccine, PPSV23, is the active comparator. In addition to studying safety/tolerability, it is hypothesized that, at 30 days postvaccination, the immunogenicity of V116 is noninferior to PPSV23 for the 12 common serotypes in V116 and PPSV23, and that V116 is superior to PPSV23 for the 9 serotypes unique to V116. It is also hypothesized that V116 is superior to PPSV23 in the percentage of participants with ≥4-fold rise from baseline in unique V116 serotypes, as measured by serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs).

NCT ID: NCT05512819 Active, not recruiting - Clinical trials for Pneumococcal Disease

NCT ID: NCT03489018 Active, not recruiting - Clinical trials for Pneumococcal Infection

The Effect of Fractional Doses of Pneumococcal Conjugate Vaccines on Immunogenicity and Carriage in Kenyan Infants

FPCV
Start date: March 21, 2019
Phase: Phase 4
Study type: Interventional

Before the introduction of pneumonia vaccines in 2000, between 700,000 - 1 million children died each year as a result of infection with the bacteria Streptococcus pneumoniae and the resulting diseases, namely, meningitis, sepsis and pneumonia. Most of the deaths were in Africa and Asia. Where the vaccines have been introduced, they have been highly effective and have already reduced disease. However, at 10 USD per child, they are not affordable to most low-income countries without financial support from Gavi, the Vaccine Alliance. This project aims to assess whether lower doses of the two commercially available pneumonia vaccines can protect Kenyan infants as well as the full dose. The results could be used to increase the affordability of the pneumonia vaccine, and enable delivery of the vaccine to continue in the absence of Gavi support.

NCT ID: NCT03102840 Active, not recruiting - Clinical trials for Streptococcus Pneumoniae Infection

Understanding Pneumococcal Carriage and Disease 2017-2020

Start date: June 26, 2017
Phase:
Study type: Observational

Streptococcus pneumoniae is a type of bacteria that is carried (lives) in the nose of most individuals and can sometimes go on to cause severe infections such as meningitis and pneumonia. There are over 100 types of pneumococcus, and children in the UK have been routinely immunized against pneumococcal disease since 2006. A vaccine against 13 types of pneumococcus (PCV 13) was introduced into the UK in 2010, replacing a previous version that prevented 7 types. Pneumococcal carriage in the Thames Valley region has been studied over the last 7 years with carriage rates having been shown to be reflective of potential severe pneumococcal disease and hence vaccine effect. The main purpose of this study is to see whether the pneumococcal immunization program has changed the frequency and nature of pneumococcal bacteria carried by children, as this may give a clue as to what changes in pneumococcal disease are likely to be seen in the future. In addition, this study is especially timely given the possibility of a change in the PCV 13 immunization schedule that is currently being assessed in the 'Sched3' Immunization study (NCT02482636). Obtaining accurate baseline data will be important in informing the interpretation of any subsequent data on carriage rates obtained following introduction of the new schedule. This study will enrol up to 1600 children aged 13 to 48 months living in the Thames Valley and South Midlands and which have had three doses of 13-valent pneumococcal conjugate vaccine. In addition, up to 800, 6-12 month old children who have received a priming dose of PCV13 will be recruited. The study consists of one visit done at a convenient venue (GP surgeries, educational/ play settings, or home) where a single nasal swab and an optional finger-prick blood sample for a sub-set of 632 participants, will be performed. No additional follow-up is needed. The study recruitment period will be from 2017 onwards.

NCT ID: NCT02012309 Active, not recruiting - HIV Clinical Trials

Mechanisms of Impaired HIV-associated B Cell and Pneumococcal Vaccine Responses

Start date: August 2014
Phase: N/A
Study type: Interventional

Human Immunodeficiency Virus (HIV) infection is complicated by high rates of infections and cancers which are often the cause of death rather than the HIV/acquired immune deficiency syndrome (AIDS) virus itself. Treatment of HIV with antiretroviral medications has decreased the frequency of many complications by over 90%, but bacterial pneumonia remains extremely high. Current vaccines are not very effective in preventing these infections in patients with HIV infection. The investigators are studying the cells (B cells) that make antibodies to fight infection by binding to and killing bacteria. The goal is to understand how HIV impairs the ability of B cells to make antibodies in sufficient quantity and of sufficient quality to protect patients with HIV to learn how to enhance protection against these infections. The investigators also seek to understand the role of the bacteria (specifically Streptococcus pneumoniae) that normally live in the nose and throat in the development of pneumonia and other infections.

NCT ID: NCT01694329 Active, not recruiting - Clinical trials for Acute Upper Respiratory Infection

Impact of Introduction of PHiD-CV for Nunavik Children, Quebec, Canada

Nunavik2
Start date: September 2012
Phase: N/A
Study type: Observational

The objective of this study is to document the residual burden of acute upper respiratory infections (AURIs), acute lower respiratory infections (ALRIs), otitis media (OMs) and auditory functional and anatomical abnormalities in children under the age of 5 years in Nunavik who will be exposed to PHiD-CV in combination with PCV-7 or PCV-13. The comparison groups will be the cohorts of children who received no PCV vaccine (those born in 1994-1996) and those exposed to PCV-7 exclusively (those born in 2003-2007).

NCT ID: NCT00844467 Active, not recruiting - Clinical trials for Pneumococcal Infection

A Retrospective Epidemiological Study on Pneumococcal Infection in Children in Ministry of Health Hospital at EHSA Region in the Eastern Province

IPD in saudi
Start date: February 2009
Phase: N/A
Study type: Observational

The purpose of this study is to establish retrospectively the incidence rates of invasive pneumococcal disease in children aged less than 5 years. The investigators allocate the El Hasa region for the study because it has higher incidence of sickle cell anemia. The study will include data from 2003 to 2007(before introduction of the vaccine) and then for 2008 and 2009 (after introduction of the vaccine).

NCT ID: NCT00099658 Active, not recruiting - HIV Infections Clinical Trials

Safety of and Immune Response to a Pneumococcal Vaccine (PncCV) in HIV Infected and Uninfected Children

Start date: April 2005
Phase: N/A
Study type: Interventional

Infection by Streptococcal pneumoniae is a common invasive bacterial infection in HIV infected children. The purpose of this study is to determine the safety of and immune response to a pneumococcal polysaccharide-protein conjugate vaccine (PncCV) in HIV infected and uninfected children. The study will also determine the safety of and immune response to Haemophilus influenzae vaccine (HibCV) in these children. Recruitment for this study will occur at two hospitals in South Africa, and all HIV infected infants participating in this study must also be coenrolled in the CIPRA SA-Project 2 study.
