Market Growth Drivers & Opportunities

One of the strongest growth drivers in the siRNA therapeutics space is the increasing burden of chronic and genetic diseases. siRNA offers an elegant mechanism to “silence” disease-causing genes by degrading their messenger RNA, making it highly attractive for disorders where traditional drugs struggle to target the root cause. Advances in delivery systems—especially lipid nanoparticles (LNPs) and GalNAc-conjugation—have dramatically improved tissue targeting, stability, and efficacy, boosting clinical confidence in siRNA-based therapies.

Regulatory support and accelerating collaboration are amplifying this trend. Agencies in key markets are showing greater openness to RNAi-based therapies, and development timelines have shortened thanks to fast-track designations and orphan drug pathways. Strategic partnerships between large pharma and specialized biotech firms are improving access to complementary expertise, funding, and infrastructure, fueling pipeline acceleration.

Furthermore, there is immense untapped opportunity in expanding siRNA applications beyond liver disease. As delivery platforms mature, companies are targeting non-hepatic tissues for conditions such as cancer, cardiovascular disease, and neurological disorders. This diversification, paired with better manufacturing capacity and next-generation formulation technologies, promises to broaden siRNA’s therapeutic footprint.

Segmentation Analysis

The market can be analyzed across delivery platform, therapeutic application, route of administration, and end-user.

By delivery platform, the market includes lipid nanoparticle-based systemic therapies, GalNAc-conjugated siRNA, and other novel delivery systems. LNP-based therapeutics, long the backbone of siRNA delivery, remain dominant thanks to broad clinical validation. GalNAc-conjugated platforms specifically enhance liver targeting, increasing therapeutic precision and reducing dose frequency. Emerging delivery systems—such as polymeric carriers or viral vectors—are under active development to penetrate non-liver tissues.

When segmented by therapeutic application, siRNA candidates address genetic disorders, cardiovascular diseases, oncology, and infectious diseases. Genetic and rare diseases continue to be a major focus, given the high unmet need and well-defined molecular targets. Oncology is gaining ground as companies explore oncogenes previously considered undruggable, while cardiovascular applications leverage siRNA to innovate in lipid regulation and vascular biology.

In terms of route of administration, there are primarily intravenous (IV) and subcutaneous (SC) options. IV delivery remains essential for complex formulations, particularly in early-stage or hard-to-reach targets. SC administration, often enabled by GalNAc or other ligand-based platforms, is growing in appeal for chronic treatment regimens due to its patient-friendliness and improved compliance.

For end-users, siRNA therapeutics are primarily delivered via biotechnology and pharmaceutical companies, while academic and research institutions also play a key role in early discovery and preclinical development. Contract development and manufacturing organizations (CDMOs) are another important segment, as they provide specialized siRNA process development and scalable production capabilities.
