About this study
Official title: A Randomized, Double-blind, Placebo Controlled, Repeat Dose Phase 1b Study to Assess the Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Inhaled GSK3923868 During Experimental Human Rhinovirus Infection in Participants With Mild Asthma
This is a Phase 1b, single center study designed to evaluate the efficacy, safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of GSK3923868 following repeat doses in mild asthmatics during experimental human rhinovirus 16 (HRV-16) infection. The study will be conducted in two parts. Part A will determine the efficacy of GSK3923868 administration after viral inoculation (i.e., therapeutic treatment) and Part B may be undertaken to determine the efficacy of GSK3923868 administration before viral inoculation (i.e., prophylactic treatment). The purpose of this study is to establish proof-of-mechanism that GSK3923868 treatment can reduce symptoms of Human Rhinovirus (HRV) infection in a controlled setting.

What is being measured
The primary outcome is the main question the study is designed to answer.
Area under curve (AUC) of change from baseline (CfB) in total lower respiratory tract symptoms (LRTS) score from day of inoculation up to discharge
The LRTS includes cough, chest tightness, shortness of breath, wheezing, daily activity, and night time awakenings. Each symptom is assessed on a 4-point scale. The score ranges from 0 to 3, where higher points indicate more symptoms experienced and severity that restricts normal activities. Shortness of breath and wheezing will be measured on a 5-point scale and ranges from 0 to 4 in which 0 indicates no symptoms and 4 indicates symptoms at total rest and the highest level of disease severity. LRTS assessment is performed three times a day.
Measured: Baseline and up to Day 15
Secondary outcomes (8)
Maximal CfB in total LRTS score from day of inoculation up to discharge
Measured: Baseline and up to Day 15
AUC and maximal CfB in total upper respiratory tract symptoms (URTS) score from day of inoculation up to discharge
The URTS includes nasal discharge, nasal obstruction, sneezing and sore throat. Each symptom will be assessed on a 4-point scale, where 0 indicates no symptom and a higher point for more symptoms and severity that restricts normal activities.
Measured: Baseline and up to Day 15
Mean percent CfB and maximum percent decline from baseline in trough force expiratory volume (FEV1) from day of inoculation up to discharge
Measured: Baseline and up to Day 15
Mean percent CfB and maximum percent decline from baseline in morning and evening peak expiratory flow (PEF) from day of inoculation up to discharge
Measured: Baseline and up to Day 15
Number of participants with adverse events (AEs) and serious adverse events (SAEs)
Measured: Up to Day 22
Number of participants with clinically significant changes in vital signs
Measured: Up to Day 22
Number of participants with clinically significant changes in electrocardiogram (ECG)
Measured: Up to Day 22
Number of participants with clinically significant changes in clinical laboratory parameters
Measured: Up to Day 22

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing GSK3923868 in people with Pulmonary Disease, Chronic Obstructive, run by GlaxoSmithKline at 1 site in United Kingdom.
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 11 inclusion and 16 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: finished, as of the sponsor's last update on 6 May 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
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 phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Area under curve (AUC) of change from baseline (CfB) in total lower respiratory tract symptoms (LRTS) score from day of inoculation up to discharge (time frame: Baseline and up to Day 15). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 May 2024; AzTrials last refreshed its copy on 8 Nov 2026.
