Executive Industry Relevance

This isolated working heart system enables ex vivo measurement of cardiac function in large animal models, providing clinically relevant data while avoiding immunological confounders inherent in transplantation studies. The system supports cross-species applicability through adjustable perfusion pressure regulation, facilitating translational cardiovascular research. By generating quantitative pressure-volume data, it enhances target validation and mechanistic de-risking in preclinical discovery pipelines.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Scientific Value: Enables interrogation of therapeutic hypotheses through direct measurement of ventricular function in physiologically relevant large animal models.
• Operational Value: Supports biological de-risking by providing human-relevant cardiac performance data without immunological confounders.
• Predictive Value: Generates quantitative pressure-volume loops that improve confidence in target engagement and pathway modulation assessments.

Screening & Assay Development

• Assay Readiness: Produces standardized, reproducible ventricular pressure-volume measurements suitable for compound screening campaigns.
• Quantitative Output: Delivers continuous, real-time hemodynamic readouts enabling dose-response analysis and efficacy profiling.
• Scalability: Adaptable perfusion system allows consistent assay execution across different heart sizes and species.

Translational & Preclinical Research

• Disease Relevance: Maintains hemodynamic parameters that replicate in vivo conditions, supporting preclinical model validity.
• Translational Continuity: Bridges discovery findings to preclinical validation through measurable functional endpoints.
• Risk-Adjusted Decisions: Provides data to inform go/no-go progression based on cardiac safety and efficacy signals.

Pipeline & Workflow Integration

The method integrates into the discovery continuum from early target validation through preclinical assessment, delivering functional cardiac data that informs lead optimization and safety evaluation.

• Discovery Biology: Supports hypothesis testing and pathway clarification via direct ventricular function measurements in disease-relevant systems.
• Screening: Enables assay readiness through standardized, reproducible pressure-volume data collection under controlled perfusion conditions.
• Analytics: Yields quantitative dependent variable measurements (e.g., end-systolic pressure, stroke work) that allow cross-condition comparison and compound ranking.
• Translational Research: Connects to preclinical work by providing human-relevant functional outputs that align with biomarker and safety assessments.
• Enterprise Reuse: Configurable apparatus serves as a reusable platform for multiple cardiovascular targets and species, reducing redundant model development.

Operational & Enterprise Impact

• Scientific Value: Increases predictive confidence by reducing mechanistic ambiguity in cardiac target validation.
• Operational Value: Ensures reproducibility through tight regulation of coronary perfusion pressure and physiologic electrolyte maintenance.
• Strategic Value: Improves capital efficiency by enabling early identification of cardiotoxic liabilities, reducing late-stage attrition.
• Portfolio Impact: Facilitates risk-adjusted prioritization of compounds based on quantitative cardiac performance thresholds.

Implementation Considerations

• Requires expertise in cardiovascular physiology and ex vivo perfusion techniques.
• Dependent on centrifugal pumps, pressure transducers, and conductance catheters for precise hemodynamic control and measurement.
• Necessitates cross-team standardization of blood preparation, temperature regulation, and data acquisition protocols.
• Involves adaptation considerations for varying heart sizes, species-specific ionic requirements, and catheter positioning optimization.
• Limited by the open-system design, which complicates long-term temperature regulation despite enabling effluent and pressure-volume data collection.
