The Pipeline

Four indications, one bioenergetic mechanism

VTI-531 and its oral conjugate VTI-531/h-CTP are being developed across acute, chronic, rare-disease, and spaceflight applications of the same underlying mitochondrial mechanism.

Cardiac-first

Focus, with future expansion to skeletal muscle

Lead Indications

>$ B

Combined U.S. serviceable obtainable market across the four lead indications below.

Indication U.S. Population / Year Annual SOM / Year
Acute Decompensated Heart Failure 1.2M hospitalizations $1B - $3B
Heart Failure w. preserved Ejection Fraction (HFpEF) 3.3M population $6B - $8B
Friedreich's Ataxia (FRDA) 5k - 6k population $0.5B - $1B
Cardiac Muscle Atrophy (CMA) in Space Travel ~1K active/future astronauts $1B - $2B (Est.)

Indication 1 of 4

Acute Decompensated Heart Failure

VTI-531 IV during hospitalization, followed by oral VTI-531/h-CTP maintenance therapy: a precision bioenergetic rescue designed to address impaired ATP production without the added oxygen demand common to current therapies.

01 - Hospitalization

IV VTI-531 infusion during the hospital stay begins bioenergetic rescue immediately.

In-hospital rescue

02 - Bioenergetic recovery

Improves myocardial function and restores ATP generation during the recovery window.

AMPK activation

03 - Discharge

A seamless transition to once-daily oral VTI-531/h-CTP for long-term cardiac maintenance.

Once-daily oral

Mechanism of Action in ADHF

THE CHALLENGE

• Impaired ATP production
• Systemic congestion
• Reduce myocardial efficiency
• Current therapies often increase oxygen demand

After stabilization, seamless transition to once-daily oral VTI1531/h-CTP for targeted long-term cardiac maintenance — extending bioenergetic benefits beyond the hospital.

VTI1531 & VTI1531/h-CTP: A Precision Medicine Approach

VTI-531 and VTI-531/h-CTP target the underlying mitochondrial metabolic dysfunction in HFpEF, a large patient population with no approved therapies addressing this root cause.

Large Unmet Need

Affects >3 million U.S. patients. No approved therapies targeting underlying mitochondrial metabolic dysfunction.

Mechanism

VTI1531/h-CTP is expected to restore bioenergetic homeostasis via AMPK activation.

Core Pathology

Characterized by microvascular rarefaction, mitochondrial dysfunction, and impaired myocardial energy utilization.

Expected Clinical Benefit

Improved diastolic performance and left atrial function.

VTI-531/h-CTP (oral conjugate)

Cardiac-specific delivery to sustain mitochondrial function improvements. Once-daily oral dosing in development.

Indication 3 of 4

Friedreich's Ataxia (FRDA)

A precision medicine approach to a rare, genetic disease affecting roughly 1 in 40,000 people in the U.S., with onset typically in adolescence.

Healthy (no FRDA)

With FRDA

A GAA-repeat expansion in the FXN gene leads to frataxin loss, mitochondrial iron dysregulation, and bioenergetic dysfunction. The clinical consequences are severe: progressive ataxia, muscle weakness, and scoliosis; cardiomyopathy, the major cause of mortality; and diabetes, neuropathy, and neurological decline. Progressive neurodegeneration and cardiomyopathy affect more than 90% of patients, and no approved disease-modifying therapies currently exist for the underlying mitochondrial dysfunction.

VTI-531/h-CTP approach

Designed for cardiac-specific delivery to address FRDA-related cardiomyopathy and mitochondrial iron accumulation, supporting mitochondrial energy homeostasis in a way that may delay disease progression.

An oral formulation is in development for chronic use, with an IV pump option for advanced or intolerant patients.

Indication 4 of 4

Cardiac Muscle Atrophy in Microgravity

  • Microgravity causes cardiac deconditioning, mitochondrial stress, and skeletal muscle loss — impairing astronaut performance and mission readiness.
  • ViCardia’s platform is being adapted to address bioenergetic dysfunction in spaceflight-associated muscle and cardiac decline.
  • Focus: Cardiac-targeted support first, with future expansion to skeletal muscle.
