Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Randomised trial of NP202 versus placebo. NP202 is a synthetic flavonol. The mechanism of action is thought to be inhibition of pro-apoptotic kinases of the death-associated protein kinase family. NP202 has been shown to reduce rhythm disturbances in heart muscle in the ventricles, and it is compelling to discover if it similarly reduces rhythm disturbances in heart muscle in the atria. As AF is the most common rhythm disturbance in the atria, it is the most suitable target to investigate a benefit. NP202 is a tablet and dose administered is 100mg daily for 4 weeks. Adherence was monitored by drug returned at 4 weeks.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software.

Safety/efficacy
Statistical methods / analysis
A sample size of 20-50 subjects provides 46-80% power to detect a treatment difference of at least 50% reduction in the primary efficacy endpoint. Power was calculated for a two-sided t-test with a 5% Type I error rate.

Analysis sets:
• Full analysis set (FAS): All subjects randomised into the study. Subjects will be analysed according to the treatment to which they were randomised. Efficacy analyses performed in the FAS are considered supportive of analyses performed in the mITT set.
• Safety set: All randomised subjects who received at least one dose of study medication. Subjects will be analysed according to the treatment received. All safety analyses will be conducted in the Safety set.
• Modified Intention-to-treat (mITT) set: All randomised subjects who received at least one dose of study medication. Subjects will be analysed according to the treatment to which they were randomised. The primary efficacy analysis will be performed in the mITT set.
• Per-protocol (PP) set: All subjects from the mITT population who completed the study in compliance with the protocol and who reported no major violation of the study protocol. Subjects will be analysed according to the treatment to which they were randomised. The final decision to exclude a subject from the PP set will be taken during a blinded data review meeting before database lock. Efficacy analyses performed in the PP set are considered supportive of analyses performed in the mITT set.

Summary
Brief summary
NP202 has been shown to reduce rhythm disturbances in heart muscle in the ventricles, and it is compelling to discover if it similarly reduces rhythm disturbances in heart muscle in the atria. As AF is the most common rhythm disturbance in the atria, it is the most suitable target to investigate a benefit.

This is a single-centre, randomised, double blind, placebo controlled study to assess the efficacy, safety and tolerability of NP202.

Subjects will be screened during routine interrogation of their cardiac device. Eligible subjects will have a high burden of paroxysmal atrial fibrillation. They will be randomised and administered their first dose of investigational product (IP) on Study Day 1.

Subjects will take their IP dose once a day for 1 month (30 days). During this treatment period they will return to the site for study visits at Week 2, and Months 1, 2, and 3. Month 3 is the end of the Treatment Period. Subject will return for follow up and the final study visit at Month 4.

A Data Monitoring Committee (DMC) will review safety data at agreed recruitment and progression milestones to provide independent oversight of subject safety.

Armaron Bio Pty Ltd has provided the study drug at no cost. They have not have provided any funding and the study investigators have full intellectual property and rights over the study data.
