Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients who are eligible to join the study will be randomised into three groups. Women will be using NR - Nicotinamide Riboside (TRU NIAGEN - TGA listed ARTG number 328365), as oral capsules, at the dosage of 250mg, 1000mg or placebo once a day for six weeks before the trigger (36 hours before the egg collection) in an IVF treatment cycle. As a strategy to monitor adherence to the intervention, the research nurse will call each participant after 14 days of medication use to check for compliance. In addition, after the participant’s first clinic visit, (approximately 28 days since commencing the study medication), the participant will be seen by research staff to count their study medication to check for compliance.

Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
Descriptive statistics will be presented by mean, SD, maximum and minimum for continuous variables, and the number of cases (n) and rate (%) for dichotomous variables. To explore the association between the number of retrieved oocytes and the number of blastocysts, univariable and multivariable regression analyses will be used. This study is a proof-of-concept trial to evaluate whether there is any evidence of the benefit of NR compared with the placebo.
