FOSTER CITY, Calif., May 15, 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 reported financial results for the first quarter ended March 31, 2023 and corporate updates.

“We are excited to announce plans to share key clinical and preclinical updates across our three lead programs at upcoming scientific congresses and look forward to several important clinical milestones later this year,” said Sen Sundaram, chief executive officer at Terns. “We anticipate top-line data from our Phase 2a DUET trial of TERN-501 as a treatment for NASH in the third quarter and the initiation of Phase 1 clinical trials in our chronic myeloid leukemia (CML) and obesity programs in the second half of this year. In addition, I’m impressed with the progress our partner, Hansoh, has made in enrolling the Phase 1 trial in China so quickly and hope we will see early data accepted for presentation by the end of the year. We continue to rapidly advance our development programs with the goal of making a significant difference in the lives of people living with serious diseases.”

Recent Developments and Anticipated Milestones

TERN-701: Oral, allosteric BCR-ABL tyrosine kinase inhibitor (TKI) for chronic myeloid leukemia (CML)

• Terns expects to initiate a clinical trial for TERN-701 in the United States in the second half of 2023, with potential top-line readouts from initial dose-escalation cohorts in 2024
  • The Phase 1 trial for TERN-701 is expected to include sites from U.S., Europe and other countries
• A poster detailing non-clinical xenograft activity of TERN-701 will be presented at the American Society for Pharmacology and Experimental Therapeutics (ASPET) on May 18, 2023 at 5:00 PM CDT
• A trial-in-progress (TiP) poster and status update will be presented at the 2023 ASCO Annual Meeting on June 5, 2023 at 8:00 AM CDT summarizing the ongoing Phase 1 study of TERN-701 (HS-10382) in China
  • The Phase 1 trial is a dose-escalation and dose-expansion trial (NCT05367700) evaluating the tolerability, efficacy, and pharmacokinetics of once-daily TERN-701 (HS-10382) in approximately 100 people with CML in China conducted by Terns’ partner Hansoh Pharmaceutical Group
    
• Terns welcomed Emil Kuriakose, M.D. as Chief Medical Officer of Terns Oncology in May 2023. Dr. Kuriakose brings more than a decade of oncology clinical development and medical affairs experience
  
• Terns plans to host a virtual R&D event with a focus on the evolving CML treatment paradigm and the potential role for TERN-701 in July 2023

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 (farnesoid X receptor (FXR) agonist), completed enrollment in February 2023 with top-line data expected in the third quarter of 2023
  • 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

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

• Terns’ lead GLP-1 receptor agonist program remains on track to initiate a Phase 1 first-in-human clinical trial in subjects with elevated BMI in the second half of 2023, with top-line data expected in 2024
• A poster evaluating activity of TERN-601 in transgenic mice expressing human GLP-1 receptor will be presented at a major diabetes conference in June 2023

TERN-800: Oral, small-molecule glucose-dependent insulinotropic polypeptide receptor (GIPR) modulators for obesity

• Lead structural series of GIPR modulators have been identified, with lead optimization efforts underway
• Candidate nomination and initiation of IND-enabling activities expected in 2024
• GIPR modulators have the potential for combination with GLP-1 receptor agonists, such as TERN-601
