FOSTER CITY, Calif., Nov. 09, 2022 (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 reported financial results for the third quarter ended September 30, 2022 and corporate highlights.

“The third quarter marked an exciting period for Terns, as we continued to accelerate development of our three lead programs in indications with large unmet need. With the completion of our $65 million financing in August, we are well-positioned to advance TERN-701 in CML and TERN-601 in obesity into the clinic in the United States in 2023. We also look forward to top-line data from the Phase 2a DUET trial evaluating TERN-501 monotherapy and in combination with TERN-101, the first trial to assess both THR-β and FXR agonists in NASH, in the second half of 2023. We look forward to continued momentum in 2023 and multiple important milestones for Terns’ product candidates next year,” said Sen Sundaram, chief executive officer at Terns.

Recent Developments and Anticipated Milestones

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

• Terns intends to initiate a Phase 1 clinical trial for TERN-701 in the United States in the second half 2023 with potential interim top-line readouts from initial cohorts in 2024
• TERN-701 is Terns’ proprietary, allosteric BCR-ABL TKI, designed to target the ABL myristoyl pocket, for the treatment of chronic myeloid leukemia (CML)
  • Allosteric TKIs, which bind to the myristoyl-binding pocket, represent a new treatment class for CML and have the potential to address active-site TKI shortcomings, including off-target activity and limited efficacy against active site resistance mutations
  • TERN-701 aims to address the limitations of active-site TKIs with the goal of achieving improved tumor suppression through a combination of (1) potent activity against BCR-ABL including a broad range of mutations, and (2) improved safety and tolerability profiles
• Terns retains all worldwide development and commercialization rights outside of greater China
  • TERN-701 is out-licensed to Hansoh Pharmaceutical Group Company Limited (Hansoh) for development in the greater China region, with Hansoh responsible for all development costs in China
  • The Phase 1 trial in China is advancing. This trial is a dose-escalation and dose-expansion trial (NCT05367700) evaluating the tolerability, efficacy, and pharmacokinetics of TERN-701 in approximately 100 patients with CML

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

• Investigational new drug (IND)-enabling activities for TERN-601, Terns’ lead GLP-1 receptor agonist program, remain on track with the goal of initiating a Phase 1 first-in-human clinical trial in obesity in 2023
  • The Phase 1 clinical program for TERN-601 is expected to include a single ascending dose trial and a multiple ascending dose proof-of-concept trial in obese healthy volunteers and/or people with Type 2 diabetes
  • Potential endpoints may include changes in body weight and glycemic control parameters
  • Top-line data expected in 2024
• TERN-601 is Terns’ proprietary orally administered small-molecule GLP-1R agonist for the treatment of obesity
  • Terns has identified structures believed to be suitable for oral administration as a single agent or in combination with other drug candidates within its pipeline, including small molecule glucose-dependent insulinotropic polypeptide receptor (GIPR) modulators

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

• Terns presented positive data from Phase 1 clinical trial of TERN-501 in NASH at AASLD’s The Liver Meeting® in November 2022
  • Among 24 treated participants TERN-501 was generally well tolerated and exhibited dose-dependent pharmacokinetics with low variability
  • TERN-501-treated participants experienced increases in sex-hormone binding globulin (SHBG), a key pharmacodynamic marker of THR-β engagement linked to decreases in levels of atherogenic lipids and NASH histologic efficacy, which were time- and dose-dependent and highly associated with TERN-501 exposure
• The Phase 2a DUET trial (NCT05415722) evaluating TERN-501 monotherapy and in combination with TERN-101, the first trial assessing both THR-β and FXR agonists in NASH, remains ongoing
  • 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 changes in MRI-PDFF (combination vs. placebo) and MRI corrected T1, or cT1 (TERN-501 monotherapy vs. placebo as well as 501+101 combination vs. placebo)
  • Top-line data expected in the second half of 2023
• TERN-501 is a THR-β agonist with high metabolic stability, enhanced liver distribution and greater selectivity for THR-β compared to other THR-β agonists in development

Pre-clinical and discovery programs: TERN-201 (VAP-1) and TERN-800 series (GIPR modulator program)

• Terns is conducting pre-clinical in vivo studies exploring TERN-201, a vascular adhesion protein-1 (VAP-1) inhibitor co-administered with immune checkpoint inhibitors (e.g., anti-PD1 and anti-CTLA4 antibodies) to assess the potential for TERN-201 to enhance response rates in solid tumors
• Discovery efforts are ongoing for the TERN-800 series of small molecule GIPR modulators for obesity, with the potential for combination with GLP-1 receptor agonists, such as TERN-601

Business Update

• Terns closed its August 2022 underwritten offering of 12,250,000 shares of its common stock at $2.42 per share and, to certain investors in lieu of common stock, pre-funded warrants to purchase 14,630,000 shares of common stock at a price of $2.4199 per pre-funded warrant. The gross proceeds to Terns for the offering were approximately $65.0 million, before deducting underwriting discounts and commissions and other offering expenses
• Terns anticipates existing cash to be sufficient to fund operations into 2025, including expected clinical trial readouts for three product candidates across three indications during that time period
