China’s National Medical Products Administration (NMPA) has been streamlining approval processes for innovative therapies, facilitating the development and commercialization of RNA-based treatments.
Emerging Trends
- Acceleration in FDA Approvals of Nucleic Acid-Based Therapies: The approval landscape for nucleic acid drugs has expanded rapidly. The U.S. FDA granted accelerated approval to tofersen (QALSODY) in April 2023 for SOD1-mutant ALS, representing the first antisense therapy for this condition. In the same year, vutrisiran received approval for hereditary transthyretin-mediated amyloidosis, administered quarterly through subcutaneous delivery. These advancements indicate increasing regulatory confidence in antisense and RNA interference (RNAi) modalities.
- Advances in Chemical Optimization and Precision Delivery: Substantial progress has been observed in chemical modification strategies that enhance stability, potency, and targeted delivery of oligonucleotide drugs. GalNAc-siRNA conjugation is now widely used to achieve efficient and selective hepatocyte targeting at lower doses. Modified chemistries such as locked nucleic acid (LNA) and constrained ethyl (cEt) designs provide increased nuclease resistance and high binding affinity, supporting the development of second-generation antisense oligonucleotides (ASOs) and siRNAs with improved therapeutic performance.
- Growth of Personalized and N-of-1 Antisense Therapeutics: The antisense platform has demonstrated viability for highly individualized treatment approaches. The development of milasen, a patient-specific ASO for Batten disease, provided a notable example of rapid design and emergency-use deployment within months. The feasibility of such customized therapeutics is expected to drive broader adoption of N-of-1 strategies for ultra-rare genetic disorders, supported by streamlined design and testing workflows.
- Expansion of the Late-Stage Clinical Pipeline: The clinical pipeline for oligonucleotide therapies has expanded to include a wider range of therapeutic areas. Multiple candidates have progressed to phase III development, such as tofersen for ALS and inclisiran for familial hypercholesterolemia. In a pivotal study with 482 participants, inclisiran achieved a 39.7% reduction in LDL-cholesterol at 16 months. This pipeline expansion reflects the increasing maturity and validation of oligonucleotide-based interventions across neurology, cardiometabolic diseases, and rare genetic conditions.
Use Cases
- Givosiran for Acute Hepatic Porphyria: Givosiran, a GalNAc-conjugated siRNA, reduces hepatic ALAS1 expression to prevent accumulation of toxic metabolites. In a 94-patient study, 74% of treated individuals experienced fewer porphyria attacks. Monthly dosing demonstrated sustained efficacy and acceptable tolerability, although routine monitoring of liver and kidney function is advised.
- Inotersen for Hereditary Transthyretin Amyloidosis (hATTR): Inotersen, incorporating 2′-O-MOE chemistry, targets TTR mRNA to decrease pathogenic protein levels. A 66-week, randomized phase III trial involving 112 treated and 60 placebo patients showed significant improvement in neuropathy impairment metrics. These findings confirmed the therapeutic value of inotersen for polyneuropathy associated with TTR mutations.
- Fitusiran for Hemophilia A and B: Fitusiran employs siRNA-mediated suppression of antithrombin to rebalance coagulation pathways. A phase II study with 25 participants demonstrated an 81% reduction in antithrombin mRNA, accompanied by a decline in annualized bleed rate from 12 to 1.7 events over 13 months. These results highlight strong efficacy in bleed prevention with monthly administration.
- Inclisiran for Heterozygous Familial Hypercholesterolemia: Inclisiran targets PCSK9 mRNA and is administered twice yearly. In a 482-subject phase III trial, the therapy achieved a 39.7% LDL-cholesterol reduction at 16 months, whereas the placebo group recorded an 8.2% increase. Approximately 65% of treated patients attained LDL-C concentrations below 100 mg/dL, underscoring consistent lipid-lowering durability and dosing convenience.
