AstraZeneca and Aptamer Group Collaborate to Enhance siRNA Therapies
AstraZeneca, in collaboration with UK biotech firm Aptamer Group, is set to revolutionize small interfering RNA (siRNA) therapies through the utilization of Aptamer’s Optimer delivery system. The partnership, commencing with pre-clinical lab data and advancing to animal studies, aims to tackle the challenge of off-target effects in siRNA therapies, a significant hurdle in the realm of drug development. Market optimism was evident as Aptamer’s shares surged by 18% subsequent to the announcement.
The Optimer system has exhibited efficacy in treating fibrotic liver in vitro and holds the potential to transform the targeted delivery of siRNA molecules. Dr. Arron Tolley, CTO of Aptamer Group, conveyed enthusiasm about the collaboration, emphasizing its capacity to expedite the advancement of Optimer technology. Notably, the system selectively targets activated hepatic stellate cells, vital for addressing fibrotic liver disease, while leaving other liver cells unaffected.
This collaborative venture is emblematic of the broader trend in which major pharmaceutical companies are displaying keen interest in innovative biotech solutions. Aptamer is also venturing into potential licensing agreements with other leading pharmaceutical firms, underscoring the escalating industry interest in their technology. siRNA therapies hold promise for the treatment of a wide spectrum of diseases encompassing oncology, fibrosis, and neurological disorders, among others.

Did You Know?
- siRNA Therapies:
- Small interfering RNA (siRNA) therapies utilize RNA interference to silence specific genes, thereby thwarting the production of harmful proteins. This technology shows promise in treating diseases caused by overactive or mutated genes, such as certain cancers, fibrosis, and neurological disorders.
- Optimer Delivery System:
- The Optimer delivery system, developed by Aptamer Group, signifies a novel approach to augment the effectiveness of siRNA therapies. It harnesses aptamers, short, single-stranded DNA or RNA molecules, to selectively target and transport siRNA to precise cells or tissues, minimizing off-target effects—an inherent challenge in siRNA therapy that can lead to side effects.
- Off-Target Effects in Drug Development:
- Off-target effects occur when a drug interacts with proteins or receptors unintendedly, resulting in unintended biological responses. These effects can lead to adverse side effects and can diminish the drug's efficacy and safety. Addressing off-target effects is a significant challenge in drug development, particularly for siRNA therapies, where precise delivery is crucial for effective treatment.
