Executive Industry Relevance

Next-generation polymerized hemoglobin-based oxygen carriers (PolyhHb) in ex vivo lung perfusion (EVLP) models address a critical bottleneck in donor lung assessment and preservation. By enabling more precise evaluation and maintenance of marginal donor lungs, these solutions support predictive confidence at the organ selection inflection point and expand the transplantable donor pool. This innovation directly impacts translational continuity and risk-adjusted advancement in organ transplantation pipelines.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables mechanistic interrogation of oxygen carrier performance in organ preservation.
• Supports biological de-risking by comparing PolyhHb to traditional perfusates in controlled EVLP models.
• Facilitates predictive confidence in donor lung viability assessment workflows.

Screening & Assay Development

• Establishes validated EVLP systems for quantitative comparison of perfusate formulations.
• Standardizes physiological readouts such as pulmonary vascular resistance and compliance for reproducible screening.
• Enables scalable evaluation of novel oxygen carriers for downstream translational studies.

Translational & Preclinical Research

• Aligns with disease-relevant models for preclinical assessment of lung preservation strategies.
• Supports continuity from discovery-stage perfusate optimization to preclinical validation in transplant models.
• Provides risk-adjusted data for advancing novel perfusates toward clinical translation.

Pipeline & Workflow Integration

PolyhHb-based perfusate testing in rat EVLP models bridges early discovery, screening, and preclinical validation within the organ preservation and transplantation workflow.

• Discovery Biology: Enables hypothesis testing on oxygen carrier efficacy and safety in organ preservation.
