DUR-928 is the lead product candidate in DURECT’s Epigenetic Regulator program. It is an endogenous, orally bioavailable small molecule that has been shown in nonclinical studies to modulate the activity of nuclear receptors playing an important regulatory role in cellular functions such as lipid homeostasis, inflammation, and cell survival.

DUR-928 is a sulfated oxysterol—representing a new class of therapeutics with a novel mechanism of action. DUR-928 epigenetically modifies gene activity without changing the DNA sequence itself.

Over 200 individuals have been dosed with DUR-928 by oral (PO), intramuscular (IM), or intravascular (IV) administration in a series of Phase 1 clinical trials. DUR-928 was well tolerated at all doses. There was minimal food effect in the oral administration studies and no accumulation with repeat dosing in any of these studies.

DUR-928 has demonstrated positive efficacy and safety in a Phase 2a clinical trial in alcoholic hepatitis (AH), via intravenous administration, and encouraging topline data in a Phase 1b trial in nonalcoholic steatohepatitis (NASH), via oral administration.

Additonally, DUR-928 is being studied in a Phase 2 trial in COVID-19 patients with acute liver or kidney injury, via intravenous administration.

DUR-928 is an investigational product and has not been approved by the FDA for marketing in the U.S. for any indication.
