Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
PB01 solution for oral inhalation is administered using a nebuliser and consists of PB01 in 20mM sodium phosphate buffer and 500mM sodium chloride, pH7.

A randomised, double blind, placebo-controlled, two period crossover study in healthy male participants. Over the two Treatment Periods, all participants will be randomised to receive a single orally inhaled dose of either 30mg PB01 or Placebo (in either sequence) at each Treatment Period. Investigational Medicinal Product (IMP) will be administered by an Aerogen Aeroneb Go vibrating mesh nebuliser for a duration of 15 minutes. Participants will be trained on the use of the Aeroneb Go nebuliser. An inhaled lipopolysaccharide (LPS) challenge (30 microgram) will be administered 1 hour post commencement of the IMP dose administration. The total dose of 30 microgram LPS (from Escherichia coli 026:B6 (Sigma)) will be delivered by a total of 5 inhalations using a calibrated breath activated nebuliser.

Following Screening, eligible participants will be admitted to the study unit on Treatment Period 1 Day 1 and will be randomised in a 1:1 ratio to receive either PB01 followed by Placebo or Placebo followed by PB01 in a two period crossover design. IMP will be administered on Treatment Period 1 Day 1 followed by the LPS challenge. Administration of the IMP and LPS will be performed at the study unit under the supervision of the clinical site personnel and participants will be confined to the study unit overnight (i.e. 24 hours) and discharged from the study unit after completion of all study procedures on Treatment Period 1 Day 2.

There will be a minimum of 24 days and a maximum of 65 days wash-out between dosing on Treatment Period 1 Day 1 and Treatment Period 2 Day 1.

At least 72 hrs and no more than 10 days prior to Treatment Period 2 Day 1 participants will attend a Baseline Visit which will include sputum sampling to determine eligibility to continue to Treatment Period 2.

On Treatment Period 2 Day 1, participants will be admitted to the study unit for IMP administration followed by the LPS challenge under the supervision of the clinical site personnel and participants will be confined to the study unit overnight (i.e. 24 hours) and discharged from the study unit after completion of all study procedures on Treatment Period 2 Day 2.

An End of Study visit will be performed 7 days (+ 5 days) after the last dose of IMP (i.e on Day 8 (+5)).

The maximum planned study duration will be 99 days per participant.

The investigator is responsible for maintaining accurate IMP accountability records throughout the study. Drug accountability will be performed by the monitor during monitoring visits to reconcile the number of IMP vials dispensed with that used/returned.

The change in neutrophil content will consist of the level of neutrophils in sputum at Screening (baseline for Treatment Period 1), 7 hours post IMP dose administration in Treatment Period 1, Baseline Visit (baseline for Treatment Period 2) and 7 hours post IMP dose administration in Treatment Period 2.

Timepoint [1] 322595 0
A single dose of 30mg PB01, will be administered via oral inhalation, one hour prior to an orally inhaled lipopolysaccharide (LPS) challenge in a two period cross over study. Participants will make 5 visits to the study unit for Screening (baseline for Treatment Period 1), Day 1 and 2 of Treatment Period 1, Baseline Visit (baseline for Treatment Period 2), Day 1 and 2 of Treatment Period 2 and End of Study Evaluation. During each visit (with the exception of the Treatment Period 2 Baseline visit) vital signs, physical examination, clinical laboratory determinations (haematology, clinical chemistry, liver function tests, coagulation, urinalysis), 12 lead electrocardiogram (ECG) reading and spirometry will be performed.
At the Treatment Period 2 Baseline visit, clinical laboratory determinations will be performed.
All participants will be monitored for adverse events and concomitant medications for the duration of the study and all information received between consent and End of Study Evaluation will be recorded in the case report form.
Secondary outcome [2] 322659 0
Sputum concentrations of PB01 measured at 7 hours post commencement of PB01 dose administration.
Timepoint [2] 322659 0
The pharmacokinetic data will consist of the concentration of PB01 in sputum at Screening (baseline for Treatment Period 1), 7 hours post IMP dose administration in Treatment Period 1, Baseline Visit (baseline for Treatment Period 2) and 7 hours post IMP dose administration in Treatment Period 2.
Secondary outcome [3] 322660 0
Changes in blood inflammatory cell counts (neutrophils, monocytes, eosinophils).
Timepoint [3] 322660 0
In both Treatment Periods 1 and 2, blood samples will be collected prior to IMP administration and following LPS challenge. Samples will be collected on Day 1, pre-dose (of IMP) and at 6 and 24 (Day 2) hours after commencement of LPS challenge.
