Study type
Description of intervention(s) / exposure
Daily treatment with nasal spray, administered to subjects by Phase 1 unit clinical staff
Two dose levels to be evaluated in 2 cohorts in an ascending dose design
Study medication (Pentosan polysulfate sodium nasal spray) will be administered once daily to 2 groups of participants (40 mg cohort and 80 mg cohort) in 2 sequential stages, A safety review will be conducted before each dose escalation
Stage 1 - Single dose (2 sprays per nostril, once a day) on day 1
Stage 2 - 7 day multiple dose (2 sprays per nostril, once a day) on days 5-11
Subjects will be admitted to the Phase 1 unit on day -1, and confined to the unit for the duration of dosing, including monitoring days where no treatment is given (day 2, 3, 4, and 12).

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Computer generated randomisation schedules will be prepared by a statistician prior to the start of the study. Subjects within a given dose level cohort will be randomised to receive Rhinosul or Placebo in a ratio of 2 to 1 respectively.
Subjects will then be allocated a corresponding pre-prepared bottle labelled with the same randomisation number. Bottles containing active and placebo will be indistinguishable apart from the randomisation number on the label
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generated randomisation schedules will be prepared by a statistician prior to the start of the study for each dose level cohort
Masking / blinding

Statistical methods / analysis
Descriptive statistical analyses will be reported for all study endpoints by stage and sampling time within each dose. Results for those on placebo will be combined. Summary statistics for the categorical variables will include counts and percentages. The descriptive summary for the continuous variables will include number of subjects (n), means, medians, standard deviations, and minimum and maximum values. All data will be listed.
This study is descriptive in nature, and no formal hypothesis testing will be performed. Any confidence intervals (CIs) generated will be 95% using exact methods, unless stated otherwise.
