Overview

SunBio develops and supplies PEG (polyethylene glycol) derivatives, chemical building blocks used to make biopharmaceutical drugs, and has its own drug products, including a treatment for a condition called neutropenia (a dangerous drop in white blood cells caused by chemotherapy) and a dry-mouth therapy.

Its neutropenia drug is supplied to Intas Pharma, which manufactures the finished product for markets including the EU, Canada, Australia, and India, with SunBio earning royalties on those sales. Listed on KOSDAQ, Korea's tech-focused small-cap board, the company's core revenue engine is its PEG-derivative supply and royalty business, while it also runs early-stage research into artificial blood and solid-state battery electrolytes.
