Dual-targeted approaches in cancer therapy: integrating siRNA and chemotherapy for improved outcomes. (PubMed, 3 Biotech)
Early clinical candidates, such as EZN-3042 and ALN-VSP, achieved target engagement and biological activity, while limitations included variable tumour uptake, dose-limiting toxicities, and complex pharmacokinetic behaviour. Translation to clinical practice will depend on optimised delivery platforms, reproducible pharmacokinetic/pharmacodynamic synchronisation, and rigorous evaluation of safety and off-target effects. Overall, current evidence highlights substantial potential for siRNA-drug co-delivery while emphasizing key challenges to overcome in achieving durable clinically meaningful outcomes.
