Enrollment: 45 participants; Allocation: RANDOMIZED; Intervention model: CROSSOVER

Brief summary:
This study will assess the safety, tolerability, and pharmacodynamics of CK-1827452 infusion in patients with stable heart failure.

Detailed description:

Arms: arm 1: 4 treatment periods with a 2 hour infusion. The 4 treatment periods consist of 3 escalating dose levels of CK-1827452 and 1 placebo treatment randomized into the dose escalation sequence. Treatment periods occur at least 7 days apart. arm 2: 4 treatment periods with a 2 hour infusion. The 4 treatment periods consist of 3 escalating dose levels of CK-1827452 and 1 placebo treatment randomized into the dose escalation sequence. Treatment periods occur at least 7 days apart. arm 3: 4 treatment periods with a 24 hour infusion. The 4 treatment periods consist of 3 escalating dose levels of CK-1827452 and 1 placebo treatment randomized into the dose escalation sequence. Treatment periods occur at least 7 days apart. arm 4: 4 treatment periods with a 24 hour infusion. The 4 treatment periods consist of 3 escalating dose levels of CK-1827452 and 1 placebo treatment randomized into the dose escalation sequence. Treatment periods occur at least 7 days apart. arm 5: 2 treatment periods with a 72 hour infusion. The 2 treatment periods are randomly assigned and consist of 1 dose level of CK-1827452 (with dose de-escalation possible depending on tolerability) and 1 placebo treatment. Treatment period 2 occurs at least 7 days after the conclusion of period 1.
