The webcast also included updates on the company's PRISM platform and initial results from the application of ADAR editing to neurology targets.
In vivo data demonstrated durable restoration of M-AAT protein in the liver of animal models following initial doses of a GalNAc-conjugated SERPINA1 AIMer.
Serum concentrations of human AAT protein remained at least three-fold higher over PBS control for 30 days post-last dose.
Wave also shared data demonstrating progress in enhancing editing activity and protein restoration following PRISM chemistry optimization.
The AIMers achieved mean editing of approximately 50% of SERPINA1 mRNA in vivo.
Also, with chemistry optimization, Wave demonstrated in vivo a four-fold increase over PBS control in AAT protein restoration in serum.
Approximately 85% of circulating AAT was confirmed to be M-AAT in treated transgenic mice.
Wave expects to have an AATD development candidate in 2022.
