Estimated Enrollment : 60 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blinded, Placebo-Controlled Study to Evaluate the Safety, Tolerability, and Efficacy of IMB-1018972 in Patients With Non-obstructive Hypertrophic Cardiomyopathy
Actual Study Start Date : June 14, 2021
Estimated Primary Completion Date : June 2023
Estimated Study Completion Date : July 2023

Arm Intervention/treatment
Experimental: IMB-1018972 200mg Drug: IMB-1018972
Modified release (MR) oral tablet

Placebo Comparator: Placebo Drug: Placebo
Matching oral tablet

Primary Outcome Measures :
  1. Safety and tolerability of IMB-1018972 as measured by incidence and severity of treatment emergent AEs (including AEs leading to study drug discontinuation and AEs leading to death), as well as incidence of treatment emergent SAEs [ Time Frame: Baseline through Week 14 Safety Follow-up ]

Secondary Outcome Measures :
  1. Change from baseline of peak oxygen consumption (VO2) and Oxygen uptake efficiency slope (OUES), measured by standardized cardiopulmonary exercise testing (CPET) [ Time Frame: Baseline, Week 12 ]
