CUPERTINO, Calif., March 30, 2015 /PRNewswire/ — DURECT Corporation (Nasdaq: DRRX) today announced that it has initiated a multi-dose Phase 1 clinical trial of an oral formulation of DUR-928, the lead molecule in DURECT’s Epigenomic Regulator Program. DUR-928 is an endogenous, small-molecule, new chemical entity (NCE) that may have broad applicability in metabolic diseases such as nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). It may also play an important role in protecting against acute kidney injury (AKI) and other types of acute organ injury.
“Following the successful completion of our Phase 1 oral, single-dose study of DUR-928, we have now begun enrollment for a Phase 1 multiple-ascending-dose trial,” said James E. Brown, President and CEO of DURECT. “This trial will provide valuable information on multi-dose pharmacokinetics that will be important as we continue moving toward Phase 2 planned for next year.”
Phase 1 Multi-Dose Study
This Phase 1 trial is a single-site, randomized, double-blinded, placebo-controlled, multiple-ascending-dose study to evaluate the safety, tolerability, and pharmacokinetics of DUR-928 when orally administered once daily for 5 consecutive days to healthy volunteers. The 20-subject study will evaluate DUR-928 in 2 consecutive 10-subject cohorts, the first receiving DUR-928 at a lower dose and the second at a higher dose.
DUR-928 is an endogenous, orally bioavailable small molecule that modulates the activity of several nuclear receptors that play an important regulatory role in lipid homeostasis, inflammation, and cell survival. A systems biology study involving over 23,000 genes showed that DUR-928 modulates the activity of more than 240 genes, including ACC, FAS, HMGR, Cyp7A1, LXR, PPARγ, NFκB/IκB, TNFα, IL-1α, IL-6, COX-2, PCSK9, and others.
The biological activity of DUR-928 has been demonstrated in 6 different animal disease models, 3 representing acute toxic or ischemic organ injury (kidney and liver) and 3 representing chronic disorders of hepatic lipid accumulation and dysfunction (NAFLD/NASH). Animal pharmacokinetics and toxicity studies have shown DUR-928 to be orally bioavailable and safe at all doses tested to date. An injectable formulation, envisioned for use in acute conditions, is currently undergoing animal testing.
About DURECT’s Epigenomic Regulator Program
DURECT’s Epigenomic Regulator Program is a collaborative effort now in its fourth year between DURECT and the Department of Internal Medicine at Virginia Commonwealth University (VCU), the VCU Medical Center, and the McGuire VA Medical Center. During the course of this program, a number of compounds that may have therapeutic utility have been identified, including the lead molecule DUR-928. DURECT holds the exclusive worldwide right to develop and commercialize DUR-928 and related molecules discovered in the program. Several clinical indications are currently under exploration, including orphan and non-orphan diseases that are both acute and chronic in nature.
