Description of intervention(s) / exposure
A randomised double-blinded placebo-controlled trial in patients with chronic rhinosinusitis.

Group 1 receives oral unlabelled Panafcortelone (Prednisolone, Aspen Pharmacare, St Leonards, NSW), in a tapering dose (25mg/day for 1 week then 12.5mg/day for 1 week then 12.5 mg every other day for 1 week) + 200ml isotonic saline with water for injection (2ml respules) as placebo delivered intranasally 2 times a day + oral placebo for antibiotic 2 tablets on day one, followed by one tablet once daily for 3 weeks

Group 2 receives topical steroid Pulmicort ® (Budesonide, 0.5mg/2ml respules) washes of the nasal cavities and sinuses delivered intranasally 2 times a day in 200 ml isotonic saline + oral placebo for antibiotic 2 tablets on day one, followed by one tablet once daily + placebo for oral steroid as mentioned above in tapering doses for three weeks

Group 3 receives oral antibiotic, Doxylin® (Doxycycline, antibiotic) tablets 2 tablets on day one (200mg), followed by one tablet (100mg) once daily + placebo for steroid in tapering doses as mentioned above + 200ml isotonic saline with water for injection (2ml respules) as placebo delivered intranasally 2 times a day for 3 weeks.

The placebo oral medication is prepared by Professional Pharmaceutical Packaging Pty, Ltd (VIC, Australia) and the placebo for Pulmicort respules was 2mL water for injections (Pfizer, Brooklyn, USA).

The patients are asked to maintain a diary for the daily documentation of treatment taken and also asked to bring back the medicine bottles and the used vials back to the pharmacy.
The three sets of treatments (one active and two placebo) are taken simultaneously by the patients. For example, in the group 1, the day 1 of the oral placebo for oral antibiotic is day 1 of week 1 for the panafcortelone.
The Placebos consists of gelatin capsules and microcrystalline cellulose USP/NF United States Pharmacopeia (USP) and the National Formulary (NF)
Both placebos are prepared by level filling the preformed gelatin capsules. This is estimated at 300mg per capsule.

Comparator / control treatment
At the commencement of the study all patients received identical appearing treatment packs, consisting of unlabelled oral medication, FLO sinus care irrigation sachets (ENT technologies, Melbourne, Australia and an irrigation bottle and vials containing a solution that were to be added to the FLO irrigation solution at each sinus lavage. Only one of the treatments in the pack had an active medical ingredient, the remaining treatments were placebo.
Each arm has an active agent and placebo representing the other two treatments and hence act as a comparator in itself to look into intra treatment effects. Also, the third group which received antibiotic will be compared against the steroid arms (group 1 and 2). Doxycycline will be given as 200mg once daily dose on day 1 followed by 100mg once daily for a total 3-week duration of treatment.
Control group
Active

Outcomes
Primary outcome [1] 321518 0
changes in patient clinical scores as seen by the Sinonasal outcome test-22 using a patient directed questionnaire.
Timepoint [1] 321518 0
Baseline at the time of recruitment
3 weeks post intervention (primary timepoint )
6 weeks post intervention
Primary outcome [2] 321519 0
Change in sinonasal microbiome profile.
This will be assessed by taking endoscopic guided nasal microbiome swabs from the middle meatus of the patients. The swabs wills be stored at -80 freezer for extraction of bacterial DNA at the completion of patient recruitment. This would be further analysed to obtain the microbiome profile in the sinuses of the CRS patients.
Timepoint [2] 321519 0
Baseline at the time of recruitment
3 weeks post intervention (primary timepoint )
6 weeks post intervention
Primary outcome [3] 321569 0
changes in patient clinical scores as seen by Lund Kennedy score.
This is a nasal endoscopic score which will be done during the endoscopic examination of the patients. This is used to assess the disease severity by scoring the oedema, polyps and discharge.
Timepoint [3] 321569 0
Baseline at the time of recruitment
3 weeks post intervention (primary timepoint )

Secondary outcome [1] 375209 0
changes in patient clinical scores as seen by Adelaide sinus symptom score using a patient directed questionnaire.
