FOSTER CITY, Calif., March 02, 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, non-alcoholic steatohepatitis (NASH) and obesity, today announced that management will participate in three upcoming investor conferences in March 2023 and provided program updates across the Company’s development programs as outlined below.

“We are delighted to have completed enrollment in the Phase 2a DUET trial of TERN-501 and express our gratitude to the people participating in this trial. We would also like to recognize the excellence of the study investigators and the Terns team in recruiting the trial. This milestone takes us one step closer to bringing TERN-501, our THR-β agonist with potentially class-leading efficacy, safety and tolerability profiles, to people living with NASH. With top-line data expected in the third quarter of this year, our team is expeditiously preparing for a potential initiation of a Phase 2b/3 clinical program in 2024,” said Erin Quirk, M.D., president, head of research and development of Terns. “We are also eagerly looking forward to a Type C meeting in May 2023, which was granted by the U.S. FDA to discuss the opportunity to leverage non-invasive endpoints to support NASH product development and, potentially, for seeking approval for NASH. While we are at the beginning of the journey towards potential pathways to accelerated approval based on non-invasive technologies, we look forward to working with the agency to explore the utility of these exciting technologies with the potential to play an important role in real world settings,” added Dr. Quirk.

“I am excited by the continued execution of our team as we strive to bring better medicines to people living with serious diseases,” said Sen Sundaram, chief executive officer of Terns Pharmaceuticals. “We expect significant progress across all of our clinical programs in 2023. In addition to NASH, we continue to progress towards initiating both our Phase 1 trial for TERN-701 in CML in the U.S. and our Phase 1 trial for TERN-601 for obesity in the second half of 2023, positioning us for three significant clinical readouts across our three lead programs by the end of 2024.”

Program Updates

The TiP abstract includes an update on enrollment progress across dose-escalation cohorts of TERN-701 (HS-10382) administered once daily
  
  • The Hansoh trial is a dose-escalation and dose-expansion trial (NCT05367700) evaluating the tolerability, efficacy, and pharmacokinetics of TERN-701 (HS-10382) in approximately 100 people with CML in China

TERN-501: Oral, thyroid hormone receptor-beta (THR-β) agonist for NASH

• The Phase 2a DUET trial (NCT05415722), evaluating TERN-501 as a monotherapy and in combination with TERN-101, completed enrollment in February 2023 with top-line data expected in the third quarter of 2023
  • Final enrollment in DUET exceeds 160, increased from the planned enrollment of 140 based on high demand for study participation
  • Primary endpoint is the relative change from baseline in liver fat content as measured by MRI protein density fat fraction (MRI-PDFF) at Week 12 for TERN-501 monotherapy compared with placebo
  • Secondary endpoints include assessment of safety and tolerability, pharmacokinetics, changes in MRI-PDFF and MRI corrected T1 (cT1)
  • DUET is the first clinical trial assessing a THR-β agonist as monotherapy and in combination with an FXR agonist in people with NASH
• FDA Type C meeting has been scheduled for May 2023
  • Terns plans to explore the opportunity to leverage non-invasive endpoints to facilitate NASH development
  • The Type C meeting, together with data from the ongoing DUET trial, is expected to inform the next stages of clinical development for Terns’ NASH program
• Terns aims to present additional preclinical data to support the dosing of TERN-501 +/- TERN-101 at a scientific conference in the second quarter of 2023
• Drug supply manufacturing is underway, and chronic toxicity data are expected by the third quarter of 2023, to enable the initiation of Phase 2b/3 development following DUET data availability

TERN-601: Oral, small-molecule glucagon-like peptide-1 (GLP-1) receptor agonist for obesity

About the DUET Trial

The Phase 2a DUET trial (NCT05415722) is a multicenter, randomized, double-blind, placebo-controlled clinical trial in noncirrhotic NASH using a factorial design including both monotherapy and combination arms of TERN-501 and TERN-101. The trial has enrolled over 160 adults with elevated body mass index (BMI ≥ 25 kg/m2) and NASH with fibrosis, but not cirrhosis, based on prior liver biopsy and/or imaging and clinical criteria. All participants must have 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 meet other inclusion and exclusion criteria. The trial includes a 12-week treatment period and a 4-week follow-up period. The primary endpoint is the relative change from baseline in MRI-PDFF at Week 12 for TERN-501 monotherapy compared with placebo. Secondary endpoints include assessment of changes in MRI-PDFF (combination vs. placebo) and cT1 (TERN-501 monotherapy vs. placebo as well as 501+101 combination vs. placebo). DUET is the first trial assessing a THR-β agonist as monotherapy and in combination with an FXR agonist in people with NASH.
