Aim: This study investigated the impact of food intake and circadian rhythms on the pharmacokinetics of

mavacamten. Materials & methods: A sensitive bioanalytical method for quantifying mavacamten in rat

plasma was developed and validated. Thismethod was applied to assess the effect of chronopharmacology

and food intake on the pharmacokinetics of mavacamten in rats. Results: A circadian variation at two

doses resulted in significant changes in the volume of distribution, clearance and time ofmaximum plasma

concentration of mavacamten (p < 0.05). In addition, food intake had an insignificant impact on the

pharmacokinetic parameters except for the time of maximum plasma concentration (p<0.05). Conclusion:

These pharmacokinetic changes and human chronotype findings will help optimize dosing time.
