What researchers measure

Primary outcomes

  1. Incidence and severity of AEs

    To assess the safety and tolerability of CK-3828136 when administered orally as single or multiple doses to healthy participants

    Time frame: Time Frame for SAD Cohorts: Day -1 - Day 7; Time Frame for MAD Cohorts: Day -1 - Day 14; Time Frame for Food Effect Cohorts: Days 1 to 7 (Treatment Periods 1 and 2)

Secondary outcomes

  1. Primary PK parameters of CK-3828136 including AUC

    To characterize the PK of CK-3828136 after single and multiple oral doses in healthy participants

    Time frame: Time Frame for SAD Cohorts: Day -1 - Day 7; Time Frame for MAD Cohorts: Day -1 - Day 14; Time Frame for Food Effect Cohorts: Days 1 to 7 (Treatment Periods 1 and 2)

  2. Changes over time from baseline in echocardiographic parameters including, but not limited to, LVEF

    To characterize the PD effects of single and multiple oral doses of CK-3828136 in healthy participants Time Frame for SAD Cohorts: Day -1 - Day 7; Time Frame for MAD Cohorts: Day -1 - Day 14

    Time frame: Time Frame for SAD Cohorts: Day -1 - Day 7; Time Frame for MAD Cohorts: Day -1 - Day 14

  3. PK parameters calculated using plasma CK-3828136 concentrations including AUC in fed and fasted state

    PK parameters following single multiple doses in fed and fasted state

    Time frame: Time Frame for Food Effect Cohort: Days 1 to 7 (Treatment Periods 1 and 2)
