A Phase 1b Multiple Oral Dose Study to Evaluate the Pharmacological Effect, Safety and Tolerability of ASP0367 in Participants With Reduced Maximum Oxygen Uptake Due to Poor Systemic Oxygen Extraction
A Phase 1b Multiple Oral Dose Study to Evaluate the Pharmacological Effect, Safety and Tolerability of ASP0367 in Participants With Reduced Maximum Oxygen Uptake Due to Poor Systemic Oxygen Extraction
The purpose of this study is to to evaluate the effect of ASP0367 on improvement of aerobic capacity relative to placebo, as well as evaluate the safety and tolerability of ASP0367 relative to placebo. This study will also evaluate the effect of ASP0367 on improvement of other aerobic capacity parameters relative to placebo, as well as evaluate the effect of ASP0367 on improvement of functional capacity relative to placebo.
The study will consist of a screening period (up to 27 days [approximately 4 weeks]), treatment period (up to 44 days [6 weeks]) and follow-up period (7 days [1 week]).
The study will be completed with an end-of-study visit (ESV). The ESV will take place 7 days (1 week) after the end-of-treatment on day 44 (week 6) or 7 days (1 week) after early discontinuation from the study.
The anticipated total duration of the study for each participant, including screening and follow-up, is approximately 75 days (11 week).
An interim analysis may be performed before the end of the study.

Participants with reduced maximum oxygen uptake due to poor SOE, defined as peak exercise ([Ca-VO2])/[Hb]) ≤ 0.85 and VO2max < 85% predicted in the absence of a cardiac or pulmonary mechanical limit, determined by aCPET within 6 months prior to day 1 or participants with reduced maximum oxygen uptake due to poor SOE, defined as peak exercise ([Ca-VO2])/[Hb]) ≤ 0.85 and VO2max < 85% predicted in the absence of a cardiac or pulmonary mechanical limit, determined by historical aCPET within 45 months of screening and confirmed reduction in skeletal muscle citrate synthase activity.
Female participant is not pregnant and at least 1 of the following conditions apply:
Female participant must agree not to breastfeed starting at screening and throughout the study period and for 28 days after final IP administration.
Female participant must not donate ova starting at first dose of IP and throughout the study period and for 28 days after final IP administration.

Male participant must not donate sperm during the treatment period and for 28 days after final IP administration.
Male participant with pregnant partner(s) must agree to remain abstinent or use a condom for the duration of the pregnancy throughout the study period and for 28 days after final IP administration.
Participant agrees not to participate in another interventional study while participating in the present study.
Exclusion Criteria:

Participant has any condition which makes the participant unsuitable for study participation.
Participant has used moderate or strong inducers of CYP3A, CYP2C8 and CYP2C19 within the 3 months prior to day -1.
Participant has cardiac troponin I (cTnI) > ULN (or cardiac troponin T > ULN if cTnI is not available) at screening.
Participant has estimated glomerular filtration rate (eGFR) calculated by the modification of diet in renal disease equation < 60 mL/min per 1.73 m^2 at screening.
Participant has at screening: total bilirubin (TBL) > upper limit of normal (ULN) or transaminase(s) (aspartate aminotransferase [AST] or alanine aminotransferase [ALT]) > ULN in the absence of elevations in creatine kinase.
Participant has diabetes mellitus (types 1 or 2).
Participant has mental conditions such as schizophrenia, bipolar disorder or major depressive disorder that has not been under control within 1 year prior to screening.
Participant has severe behavioral or cognitive problems that preclude participation in the study.
Participant has a history of suicide attempt, suicidal behavior or has any suicidal ideation within 1 year prior to screening that meets criteria at a level of 4 or 5 by using the Columbia-Suicide Severity Rating Scale (C-SSRS) or who is at significant risk to commit suicide.
Participant has undergone an inpatient hospitalization within the 30 days prior to the randomization or has a planned hospitalization or a surgical procedure during the study, which may affect the study assessments.
Participant has clinically significant respiratory disease (such as chronic obstructive pulmonary disease, cystic fibrosis, severe asthma, lung infections including tuberculosis, sarcoidosis, thoracic endometriosis, pulmonary fibrosis and lung cancers) and/or cardiac disease (medical history or current clinical findings) or prior interventional cardiac procedure (e.g., left heart catheterization which resulted in angioplasty/percutaneous coronary intervention, balloon valvuloplasty, etc.) within 3 months prior to randomization.
Participant has a pacemaker, implantable cardioverter-defibrillator or cardiac resynchronization therapy device, or has a mean corrected QT interval using Fridericia's formula (QTcF) > 450 msec for male participants and > 470 msec for female participants at screening or randomization. If QTcF exceeds these limits, 1 additional triplicate ECG can be taken on the same day in order to determine the participant's eligibility.
Participant has ECG evidence of acute ischemia, atrial fibrillation or active conduction system abnormalities at screening, with the exception of any of the following:
Participant has a seizure disorder that may interfere with their ability to complete all study requirements.
Participant has an active malignancy or any other cancer from which the participant has been disease-free for < 5 years.
Participant has a solid organ transplant and is currently receiving treatment with therapy for immunosuppression.
Participant has a positive serology test for human immunodeficiency virus, hepatitis B or hepatitis C infection at screening.
