About this study
Official title: Prevention of Acute Respiratory Infection in Taiwanese Institutionalized Elderly (PARITIE)
The purpose of this study is to assess the efficacy of Bacille Calmette-Guérin (BCG) vaccination compared to placebo against acute respiratory infections in the elderly who are less protected by standard vaccines against influenza than other age groups. The investigators hypothesize that BCG vaccination can reduce incidence of infection and severity of a range of acute respiratory infections. Patients who are residents of participating long-term care facilities (LTCFs), who agree to participate in the study, or with a legal guardian who agrees on their behalf, will be randomly assigned to receive BCG vaccination or a placebo. Participants will be followed for up to six months to assess the incidence of infection and the severity of a range of acute respiratory infections.
Read the detailed description
This is a Phase III, double-blind, randomized placebo-controlled trial comparing efficacy of BCG vaccination to that of placebo in reducing severity of a range of acute respiratory infections. Participants will need to meet eligibility criteria in order to be included in the study. Those selected will be asked to provide a blood sample for complete blood count, liver function and renal tests, tests to calculate MELD score, also serological testing.
Participants will be randomized in a 1:1 allocation to receive intradermal administration of BCG vaccination or placebo at baseline. During follow-up, the study team will monitor participants' health status by using intermittent surveys about the presence of adverse events potentially related to vaccination, clinic visits or hospitalization for acute respiratory infection, BioFire® Respiratory 2.1 panel for respiratory pathogens and disease outcome status.
The investigators will screen 980 individuals to enroll 830 participants, resulting in 415 receiving BCG vaccine and 415 receiving placebo. The proposed enrollment sample size is designed to provide 80% power to detect 60% vaccine efficacy (a relative risk of 0.4 among the vaccinated) with 0.05 type-1 error in a two-tailed test, assuming 10% lost to follow-up. The number of individuals screened assumes about 15% will not be eligible to be enrolled after screening.
Objective: To measure the impact of one-time BCG-Japan vaccination on acute respiratory infections leading to hospitalization in the elderly.
Primary Endpoint 1: The cumulative incidence of hospitalization for acute respiratory infection following BCG vaccination compared to that following placebo, starting from 14 days post-vaccination, as defined using relevant ICD-10 codes.
If BCG vaccine is shown to be effective in this age group, it will be of major benefit to both study participants and other elderly individuals at risk for acute respiratory infections and have added protection from disease. Identification of an intervention that can reduce the risk of infection and/or of being hospitalized with ARI would reduce the number of new cases and reducing the number of cases that require hospital admission and vast resources.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing BCG Vaccine in people with Acute Respiratory Infection, run by Harvard Medical School (HMS and HSDM).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 6 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To measure the impact of one-time BCG vaccination compared to placebo in reducing the occurrence of acute respiratory infection leading to hospitalization in the elderly in Taiwan (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04938323, which also lists 23 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jul 2022.
