CK-2127107 amplifies skeletal muscle response to nerve activation in humans.

ABSTRACT:

Introduction

Three studies evaluated safety, tolerability, pharmacokinetics, and pharmacodynamics of CK-2127107 (CK-107), a next-generation fast skeletal muscle troponin activator (FSTA), in healthy participants. We tested the hypothesis that CK-107 would amplify the force-frequency response of muscle in humans.

Methods

To assess the force-frequency response, participants received single doses of CK-107 and placebo in a randomized, double-blind, 4-period, crossover study. The force-frequency response of foot dorsiflexion following stimulation of the deep fibular nerve to activate the tibialis anterior muscle was assessed.

Results

CK-107 significantly increased tibialis anterior muscle response with increasing dose and plasma concentration in a frequency-dependent mann
