Type of endpoint(s)
Efficacy
Statistical methods / analysis
The primary efficacy endpoint is the incidence of post-operative atrial fibrillation.
The primary analysis will be performed using a two-sided Cochran-Mantel-Haenszel (CMH) test with treatment group and surgery type as stratification factors to compare the proportions of subjects with AF (incidence) between the NP202 and Placebo groups. The primary analysis will be based on the modified intention-to-treat analysis set.
The null hypothesis is that there is no difference in the proportion of subjects with AF between the NP202 and Placebo groups. The alternative hypothesis is that there is a difference in the proportion of subjects with AF between the groups.
A sample size of at least 160 subjects achieves 80.2% power to detect a difference of -0.2 between the proportions of the NP202 and Placebo groups. Assuming a Placebo response of 40% (pPlacebo = 0.4), this amounts to a 50% reduction in post-operative AF in the NP202 group compared to Placebo. The sample size was calculated based on a two-sided chi-test at a significance level of 5%.
A total of 180 subjects will be randomised into the study to ensure that at least 160 evaluable subjects.

Summary
Brief summary
Atrial fibrillation (AF) remains a frequent complication after coronary artery bypass graft surgery (CABG) with a rate of occurrence from 10 to 40%.. This study will assess the ability of a novel treatment (NP202) to prevent post operative atrial fibrillation in comparison to a placebo. NP202 is a small molecule that inhibits a protein that is central to atrial fibrillation. Subjects will be treated with NP202 or placebo for 3 days prior to their surgery and through the duration of their hospital stay. After surgery, the amount of atrial fibrillation will be assessed during the in hospital recovery period.
