* 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.
