SAN DIEGO, Nov. 20, 2024 (GLOBE NEWSWIRE) -- Organovo Holdings, Inc. (Nasdaq:ONVO), a clinical stage biotechnology company focused on developing novel treatment approaches in inflammatory bowel disease (IBD) including ulcerative colitis, today announces that its oral presentation of its lead clinical stage drug FXR314 by Dr. Eric Lawitz of the Texas Liver Institute and the University of Texas Health San Antonio was featured at The Liver Meeting, sponsored by the American Association for the Study of Liver Diseases (AASLD). The meeting was held November 15-19, 2024 in San Diego, California.
The presentation entitled “Pharmacokinetics, Safety and Efficacy of the Novel Non-bile Acid FXR Agonist FXR314 in Patients with Metabolic Dysfunction-Associated Steatohepatitis: Results from a Phase 2 Study” was presented on Sunday, November 17 in the MASLD and MASH – New therapies session.
Dr. Lawitz shared the complete details of the 16-week, randomized, placebo-controlled, multi-center Phase 2 study of FXR314 in MASH patients. A total of 214 patients were randomized in a 1:1:1 ratio to either 3 mg or 6 mg of FXR314, or placebo. Study results demonstrated statistically significant reduction in liver fat content from baseline in patients receiving FXR314 compared to placebo, and a safety profile demonstrating significantly lower pruritus rates than seen with other FXR agonists.
Study subjects receiving FXR314 achieved statistically significant reduction in liver fat content from baseline, with LS mean percent reduction at end of treatment of 22.8% (p=0.0010) with 3 mg and 17.5% (p=0.0267) with 6 mg doses of FXR314 compared to 6.1% in the placebo group. The proportion of subjects with >30% magnetic resonance imaging-derived proton density fat fraction (MRI-PDFF) reduction was 29.2% (p=0.0023) and 32.2% (p=0.0020) for 3 mg and 6 mg FXR314, respectively, compared to 9.5% with placebo. Investigators observed improvements in hepatocellular damage and liver function based on serological measures, with no evidence of worsening of liver fibrosis.
FXR314 was also found to be safe and well tolerated. Treatment-emergent adverse events were mostly mild to moderate in severity, with incidence comparable between FXR314 3 mg, 6 mg, and placebo. Drug-related treatment discontinuation was low in frequency and similar across groups. FXR314 did not demonstrate significant adverse events typical of the FXR class, including pruritus (3 mg 2.8%, 6 mg 4.2% and placebo 2.8%) and LDL-C levels (change from baseline of 1.5%, 4.5% and -3.6% for 3mg, 6mg, and placebo groups respectively).

“These results are encouraging as we saw FXR314 treatment resulting in liver fat reduction but did not demonstrate the expected toxicities of this class,” stated Dr. Lawitz. “Due to this unique profile, I am excited about the prospects of further evaluating FXR314 for the treatment of MASH. The intestinal activating specificity is intriguing.”
