Inclusion criteria

Participants must meet all inclusion criteria to be eligible for trial participation.

  • Males or females ≥ 50 years of age at the time of signing the informed consent.
  • Diagnosis of HFpEF as defined by European Society of Cardiology or American College of Cardiology/American Heart Association criteria
  • NYHA Functional Class II or III
  • LVEF ≥ 50% demonstrated by echocardiography (ECHO) performed at Screening with evidence of heart failure
  • Elevated NT-proBNP at Screening
  • NordicPRO-C6™ ≥ 11 ng/mL at Screening.
  • Stable dose of all concomitant HF medications for at least 4 weeks prior to Screening.
  • Body weight of at least 110 lbs (50 kg) and body mass index (BMI) within the range ≥ 18 to < 45 kg/m2.
  • Males must agree to the contraception requirements and females must be of non-childbearing potential
  • Able to understand and willing to sign a written informed consent form (ICF).
  • Willing and able to comply with trial procedures and restrictions listed in the ICF and in this protocol.

Exclusion criteria

  • Female trial participant who is pregnant or breastfeeding.
  • Known hypersensitivity to VS-041.
  • Cardiovascular disease other than HFpEF
  • Active intercurrent illness such as acute bacterial or viral infection.
  • History of illicit drug or alcohol abuse or addiction that in the opinion of the PI could affect participation.
  • Active chronic viral infection such as Hepatitis B, Hepatitis C or human immunodeficiency virus (HIV) at Screening.
  • Acute decompensated HF within 30 days of Screening
  • Lung disease within 12 months prior to Screening
  • History of an active or untreated malignancy or are in remission from a clinically significant malignancy for less than 5 years.
  • History of any other condition including psychiatric disorders that, in the opinion of the PI, may preclude the participant from following and completing the protocol.
  • Have participated within the last 6 months in a clinical study involving an investigational product.
  • Any other reason which, in the opinion of the PI, would prevent the participant from participating in the trial.

Treatment and study plan

VS-041

Drug

VS-041 high dose, VS-041 low dose or Placebo tablet BID

Placebo

Other

Placebo to match VS-041

Primary outcomes

  1. Participant incidence of treatment-emergent adverse events (TEAEs)

    Time frame: From Baseline to Day 28

    To evaluate the safety and tolerability of VS-041 in participants with HFpEF

  2. Change from baseline over time in serum NordicPRO-C6

    Time frame: From Baseline to Day 28

    To evaluate the impact of VS-041 on key biomarkers in participants with HFpEF

  3. Change from baseline over time in serum endotrophin

    Time frame: From Baseline to Day 28

    To evaluate the impact of VS-041 on key biomarkers in participants with HFpEF

  4. Change from baseline over time in serum NT-proBNP

    Time frame: From Baseline to Day 28

    To evaluate the impact of VS-041 on key biomarkers in participants with HFpEF

Secondary outcomes

  1. Pharmacokinetic profiles and parameters derived for VS-041 - Tmax

    Time frame: From Baseline to Day 28

    To assess PK of twice-daily VS-041 in participants with HFpEF

  2. Pharmacokinetic profiles and parameters derived for VS-041 - Cmax

    Time frame: From Baseline to Day 28

    To assess PK of twice-daily VS-041 in participants with HFpEF
