Gene Therapy for Heart Failure Market: Genotype-Specific Cardiomyopathy Treatment Demand, AAV-Based Cardiac Delivery Growth, and Calcium-Handling Restoration Technology Adoption to Drive Strong Market Expansion Through 2035

The global Gene Therapy for Heart Failure Market was valued at USD 2,451.8 million in 2025 and is projected to expand at a strong CAGR of 15.2%, reaching approximately USD 8,761.1 million by 2035. This growth trajectory is being driven by sustained clinical demand for genotype-specific cardiomyopathy treatment, growing utilization of AAV-based cardiac delivery platforms, and continued advancement of calcium-handling restoration technology. The market comprises a substantial clinical-stage pipeline including AB-1002, SRD-002, TN-201, TN-401, and multiple LX-series candidates, with no broadly approved gene therapy specifically for conventional heart failure currently available.

The market’s strong 15.2% CAGR reflects the field’s transition from generic cardiac function enhancement toward genotype-specific cardiomyopathy treatment, generating structured demand from cardiovascular centers above discretionary specialty pharmaceutical demand growth as this remains primarily a pipeline and emerging therapeutic market. Sustained clinical progress across BAG3-associated dilated cardiomyopathy, PKP2-associated arrhythmogenic cardiomyopathy, and MYBPC3-positive hypertrophic cardiomyopathy continues to demonstrate the field’s shift toward molecularly defined treatment approaches. Coverage extending across multiple therapeutic strategies, vector platforms, and delivery routes underscores the breadth of clinical and manufacturing infrastructure now supporting this category as it advances from Phase 1 through pivotal development stages.

Executive Snapshot

How does genotype-specific cardiomyopathy treatment demand drive the gene therapy for heart failure market?
Cardiovascular treatment centers increasingly focus gene therapy development on molecularly defined cardiomyopathy subtypes, including BAG3-associated dilated cardiomyopathy, PKP2-associated arrhythmogenic cardiomyopathy, and MYBPC3-positive hypertrophic cardiomyopathy, establishing genotype-specific treatment as a defining feature of current clinical development. As genetic testing continues to identify eligible patient populations, procurement associated with genotype-specific treatment is expected to remain a leading category through the forecast period.

What role does AAV-based cardiac delivery growth play in market expansion?
Biopharmaceutical developers continue to rely on adeno-associated virus vectors, including AAV1, AAV6, and AAV9 serotypes, for cardiac-directed gene delivery, sustaining structured demand from developers pursuing established viral vector platforms above emerging non-viral delivery alternatives.

How does calcium-handling restoration technology adoption sustain market growth?
Biopharmaceutical developers continue to advance SERCA2A-targeted and related calcium-handling restoration candidates such as SRD-002, sustaining structured demand above conventional generic cardiac function enhancement approaches. Continued clinical investment in this specific therapeutic strategy is generating demand from developers pursuing mechanistically defined heart failure treatment.

What is driving demand for gene therapy in intracoronary and intramyocardial delivery applications?
Developers pursuing intracoronary infusion delivery, consistent with AB-1002’s evaluation approach in its Phase 2 GenePHIT trial which completed enrollment of more than 170 participants across 64 sites in 12 countries, continue to establish this delivery route alongside emerging systemic intravenous administration approaches.

How does anti-fibrotic and anti-remodeling therapeutic strategy demand sustain the market?
Biopharmaceutical developers increasingly pursue anti-fibrotic and anti-remodeling gene therapy strategies alongside contractility enhancement approaches, sustaining structured demand from developers pursuing comprehensive heart failure disease modification beyond symptomatic improvement alone.

Which gene therapy for heart failure market segments are growing fastest?
The fastest-growing segments include genotype-specific cardiomyopathy treatment for BAG3, PKP2, and MYBPC3-associated disease, systemic intravenous delivery approaches, Phase 2 and pivotal-stage clinical candidates, and combination approaches alongside guideline-directed medical therapy.

Market Dynamics: Gene Therapy for Heart Failure Market

  • Cardiac contractility enhancement sustaining the leading share of current therapeutic strategy activity: Calcium-handling restoration and sarcomere protein restoration approaches continue to represent the most clinically advanced therapeutic strategies across the category.
  • AB-1002 sustaining the leading share of clinical development activity among current candidates: This program’s substantial Phase 2 GenePHIT trial enrollment continues to anchor a significant portion of overall gene therapy for heart failure development activity.
  • Genotype-specific cardiomyopathy programs sustaining structured demand above generic function-enhancement approaches: BAG3, PKP2, and MYBPC3-directed programs continue to represent an increasingly important area of pipeline differentiation.
  • AAV vector platforms sustaining the dominant delivery technology across the category: AAV1, AAV6, and AAV9 serotypes continue to represent the leading delivery platform relative to adenoviral, lentiviral, and non-viral alternatives.
  • Intracoronary delivery sustaining an established administration approach alongside emerging systemic delivery: Consistent with AB-1002’s evaluation approach, this delivery route continues to anchor current clinical activity as newer programs explore intravenous administration.
  • Phase 1 through pivotal-stage clinical development sustaining the entirety of current market activity: The absence of a broadly approved heart failure-specific gene therapy continues to concentrate all market activity within clinical-stage development.
