Nitto Denko's business development in the domain of nucleic acid drugs

Therapeutic nucleic acid drugs are short fragments of nucleic acids with defined chemical structure (sequence). These compounds have been shown to be effective in the modulation of gene expression in a highly specific manner. As a result, therapeutic nucleic acid drugs have the potential to serve as a novel therapy for various illnesses which conventionally have been difficult to combat.

Nitto Denko already is active in nucleic acid drug technology with its wholly owned subsidiary Nitto Denko Technical Corporation in Oceanside, California. NDT is currently expanding its technological development of the chemical synthesis of nucleic acid drugs.

With the acquisition of Avecia Biotechnology, Nitto Denko will further boost its business base in this drug technology domain by leveraging the additional contract manufacturing business of nucleic acid drugs.
