Terns Pharmaceuticals Presents Late-Breaking Data from Phase 2a DUET Trial of THR-β Agonist TERN-501 in NASH at AASLD The Liver Meeting® 2023
TERN-501 treatment over 12 weeks significantly improved liver fat content and fibro-inflammation in NASH patients, with low rates of gastrointestinal and no cardiovascular adverse events
TERN-501 significantly increased SHBG, a marker of target engagement and predictor of histologic response in the THR-β class
Company to host in-person investor event following late-breaking data today at 4:00 p.m. ET in Boston
FOSTER CITY, Calif., Nov. 13, 2023 (GLOBE NEWSWIRE) -- Terns Pharmaceuticals, Inc. (“Terns” or the “Company”) (Nasdaq: TERN), a clinical-stage biopharmaceutical company developing a portfolio of small-molecule product candidates to address serious diseases, including oncology, obesity and non-alcoholic steatohepatitis (NASH), today announced the late-breaking oral presentation of top-line data from its Phase 2a DUET clinical trial of TERN-501, an investigational orally administered thyroid hormone receptor-β (THR-β) agonist for the treatment of NASH. TERN-501 was evaluated alone and in combination with the Company’s liver-distributed farnesoid X receptor (FXR) agonist TERN-101. These data will be presented at The Liver Meeting®, the annual meeting of the American Association for the Study of Liver Diseases (AASLD), on Monday, November 13 at 2:00 p.m. ET in Boston, Massachusetts.
“NASH continues to be a serious, multi-faceted disease, and it is encouraging to see the additional evidence supporting the THR-β mechanism of action of TERN-501 to address these disease processes,” said Mazen Noureddin, M.D., MHSc, Professor of Medicine, Academic Institute, Houston Methodist, Director of Houston Research Institute, study presenter and principal investigator in the DUET trial. “The efficacy of TERN-501, showing a significant impact on steatosis and fibro-inflammation markers in a short period of time, coupled with its convenient oral once-daily dosing and highly positive safety profile, indicate that TERN-501 is a promising candidate for NASH treatment, either as a monotherapy or in combination with other therapies.”

|Session Title:||Late Breaking Abstract #1|
In the Phase 2a DUET trial, patients with phenotypic or prior histologic NASH were randomized to one of seven treatments: once-daily, orally administered TERN-501 (1, 3 or 6 mg), TERN-101 (10 mg), TERN-501 (3 or 6 mg) combined with TERN-101 (10 mg), or placebo. The primary endpoint was the relative change from baseline in magnetic resonance imaging proton density fat fraction (MRI-PDFF), a measure of liver fat content, at Week 12 for TERN-501 monotherapy versus placebo. The study also assessed liver fibro-inflammation as measured by MRI corrected T1 (cT1), sex hormone binding globulin (SHBG) levels, a marker of THR-β agonism in the liver, lipid levels, and other fibrosis biomarkers as well as safety and tolerability following treatment.
Late-Breaking Phase 2a DUET Top-line Data to be Presented at AASLD The Liver Meeting
- TERN-501 (6 mg) monotherapy demonstrated significant reductions in liver fat content as early as Week 6
- The study met its primary endpoint, with TERN-501 monotherapy demonstrating a mean relative reduction of 27% (p=0.0036) and 45% (p<0.0001) at 3 mg and 6 mg doses, respectively, versus a 4% reduction in the placebo group at Week 12
- A significantly higher percentage of patients achieved a ≥30% MRI-PDFF reduction in TERN-501 arms and a ≥50% reduction with TERN-501 (6 mg) monotherapy at Week 12
- TERN-501 (6 mg) monotherapy resulted in a significant and rapid decrease in cT1 with a significantly higher percentage of patients achieving a ≥80 ms reduction (recovering from an at-risk NASH category)
- TERN-501 combined with TERN-101 resulted in efficacy improvement or maintenance compared to TERN-501 monotherapy
- TERN-501 monotherapy arms demonstrated significant increases in SHBG and improved lipid levels, including significant reductions in apolipoprotein B (ApoB) and a decrease in low-density lipoprotein (LDL) levels, when combined with TERN-101
- TERN-501 was generally well tolerated, with treatment-related adverse events (AEs) similar to the placebo group
- Overall, there were low rates of gastrointestinal AEs reported similarly across all treatment arms
- No treatment-related cardiovascular AEs or serious AEs were reported
“The acceptance of this late-breaking analysis of our Phase 2a DUET study for patients with non-cirrhotic NASH at one of the most prestigious liver meetings in the world is further validation that we are advancing important research that has the potential to transform the treatment of this serious disease,” said Erin Quirk, M.D., president and head of research and development at Terns. “These top-line data of TERN-501 are encouraging, with significant reductions in key biomarkers including liver fat content, MRI-PDFF, and cT1, a marker of fibro-inflammation. The positive efficacy and safety profile of TERN-501 supports our belief that it has the potential to become the THR-β monotherapy of choice and potentially a mainstay backbone of combination therapies for people living with NASH who are in desperate need of treatment options.”
The presentation will be made available on the Scientific Publications portion of the Terns website.

About the Phase 2a DUET Trial
The Phase 2a DUET trial (NCT05415722) is a multicenter, randomized, double-blind, placebo-controlled clinical trial in non-cirrhotic NASH, designed to evaluate efficacy and safety of TERN-501 as a monotherapy and in combination with TERN-101. The trial enrolled over 160 adults with body mass index (BMI) ≥ 25 kg/m2 and pre-cirrhotic NASH identified based on prior liver biopsy and/or imaging and clinical criteria. All participants had liver fat content measured by magnetic resonance imaging proton density fat fraction (MRI-PDFF) of ≥10%, MRI corrected T1 (cT1) relaxation time of ≥ 800 msec and met other inclusion and exclusion criteria. The trial included a 12-week treatment period and a 4-week follow-up period. The primary endpoint was the relative change from baseline in MRI-PDFF at Week 12 for TERN-501 monotherapy compared to placebo. Secondary endpoints included assessments of relative change from baseline in MRI-PDFF for TERN-501+TERN-101 combination compared to placebo and change from baseline in cT1 for TERN-501 monotherapy compared to placebo as well as for TERN-501+TERN-101 combination therapy compared to placebo.
About Non-alcoholic Steatohepatitis (NASH)
NASH is a severe form of non-alcoholic fatty liver disease (NAFLD) that affects up to 20 million people in the United States, and up to 5% of the global population, and for which there is currently no approved therapy in the United States or Europe. In a study published in Hepatology in 2018, lifetime costs of treating and managing NASH patients in the United States in 2017 were estimated to be over $220 billion, in the absence of approved therapies. NASH is a multifaceted disease that involves three distinct pathogenic hepatic disease processes: accumulation of excess fat in the liver (steatosis), inflammation and fibrosis. In addition to these three disease processes, NASH patients often exhibit elevated levels of glucose and atherogenic lipids, are overweight or obese and accumulate excessive lipotoxic fat. Severe progression of NASH can lead to cirrhosis, decompensated liver disease and increased risk for hepatic carcinoma and liver-related mortality.
