Phase 1
Terminated
Conditions
Healthy Participants
Interventions
Drug: Placebo for CK-3828136
Registration Number
NCT05662215
Lead Sponsor
Cytokinetics
Brief Summary

1. Learn about the safety and tolerability of CK-3828136 after a single dose and multiple doses in healthy subjects.

2. Find out how much CK-3828136 is in the blood after a single dose and multiple doses.

3. Determine the effect different doses of CK-3828136 on the pumping function of the heart.
