GIAZO Market Analysis and Financial Projection

Last updated: February 3, 2026

What is GIAZO and its current development status?

GIAZO is a proprietary formulation combining glibenclamide with guaiazulene, primarily developed for targeted treatment of type 2 diabetes through enhanced bioavailability and reduced gastrointestinal side effects. The formulation leverages guaiazulene’s anti-inflammatory properties to mitigate common adverse effects of glibenclamide, such as gastric irritation.

GIAZO has completed phase III clinical trials in China, demonstrating comparable efficacy to standard glibenclamide with an improved safety profile. Approval processes are underway in select Asian markets, with regulatory submissions expected by Q4 2023. No FDA or EMA approval has been granted as of this date.
