The Advanced Therapy Based on Gene market is segmented by Type, reflecting the technological frameworks underpinning gene delivery. The primary categories include Viral Vectors, Non-Viral Vectors, and Oligonucleotides. Viral vectors, such as AAVs and lentiviruses, dominate due to their high transduction efficiency in clinical trials, particularly in oncology and rare diseases. Non-viral vectors, including plasmid DNA and lipid nanoparticles, are gaining traction for their reduced immunogenicity and scalability, though they face challenges in delivery efficacy. Oligonucleotides, such as antisense or CRISPR-based therapies, represent a niche but rapidly growing segment, driven by precision gene-editing applications. These subtypes collectively shape Advanced Therapy Based on Gene segmentation, with viral vectors accounting for ~55% of the market share in 2023, followed by non-viral (30%) and oligonucleotides (15%).
