The Types classification captures the molecular and biologic platforms that generate novel antiviral candidates. Small‑molecule inhibitors dominate with an estimated 45 % share, owing to established synthesis routes, oral bioavailability, and scalable manufacturing. Within this class, protease inhibitors, polymerase blockers, and entry‑fusion antagonists represent the primary sub‑categories, each aligned with distinct viral life‑cycle stages. Nucleoside/nucleotide analogues account for roughly 25 % of the market, leveraging chain‑termination mechanisms that are broadly applicable across RNA and DNA viruses. Monoclonal antibodies contribute about 15 %, offering high specificity and rapid deployment for emergent outbreaks, though they are limited by intravenous administration and higher cost structures. RNA‑interference (RNAi) agents and CRISPR‑based antivirals together comprise the remaining 15 %, reflecting early‑stage commercialization and significant R&D investment. The proportional weight of each type directly influences total market size, as development costs, regulatory pathways, and pricing models differ markedly across platforms. Understanding this Novel Antiviral Drugs segmentation is essential for investors evaluating pipeline risk‑adjusted returns.
