Drug intelligence / Profile preview
DIA03-NTB is an exploratory, preclinical-stage drug delivery program developed by Dianosic. It utilizes a specialized intranasal insert designed for nose-to-brain (NTB) delivery, leveraging the company's proprietary polymer elution technology derived from its DIA01-R platform. The system is intended to provide sustained release of therapeutic agents directly to the central nervous system, bypassing the blood-brain barrier. While the specific active pharmaceutical ingredients have not been publicly disclosed, the program is currently targeting the treatment of neurological and psychiatric conditions, specifically schizophrenia and Parkinson's disease.
