• TERN-701 (allosteric BCR-ABL inhibitor) advances into Phase 1 trial for CML in China
  
• IND-enabling activities for TERN-601 (GLP-1R agonist) remain on track; Phase 1 obesity trial initiation expected in 2023
  
• Initiated dosing of TERN-501 (THR-β agonist) Phase 2a DUET combo clinical trial for NASH; top-line data expected in second half of 2023
  
• Cash and equivalents of $140 million provides runway into 2025, supporting three expected clinical trial readouts across three product candidates and three indications

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 second quarter ended June 30, 2022 and corporate highlights.

“During the second quarter, Terns saw significant progress in advancing three of our internally discovered, small-molecule product candidates towards key clinical readouts in chronic myeloid leukemia, obesity and NASH,” said Sen Sundaram, chief executive officer at Terns. “We look forward to assessing the differentiation of these three product candidates, each of which target clinically validated mechanisms of action.”

Recent Developments and Anticipated Milestones

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

• In May 2022, Hansoh Pharmaceutical Group Company Limited (Hansoh) initiated dosing of TERN-701 in a Phase 1 dose-escalation and dose-expansion trial in approximately 100 patients with CML (NCT05367700)
  • The objectives of this trial are to evaluate the tolerability, efficacy, and pharmacokinetics of TERN-701 in CML
• TERN-701 is Terns’ proprietary, allosteric BCR-ABL TKI, designed to target the ABL myristoyl pocket, for the treatment of chronic myeloid leukemia (CML)
  • TERN-701 aims to address limitations of the only FDA-approved allosteric BCR-ABL TKI with the goal of achieving improved tumor suppression through a combination of: (1) potent activity against CML including a broad range of mutations, (2) improved PK to enable potential once-daily dosing, and (3) minimal food or fasting requirements
• TERN-701 is out-licensed to Hansoh for development in the greater China region. Hansoh is responsible for all development costs in China, including the ongoing Phase 1 trial
  • Terns retains all worldwide development and commercialization rights outside of greater China, as well as access to data generated by Hansoh in China
• Terns is exploring options for the development and commercialization of TERN-701 outside of China, including potential internal development and/or additional strategic partnerships

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

• IND-enabling activities for TERN-601, Terns’ lead GLP-1R development candidate, are proceeding on-track with the goal of initiating a first-in-human clinical trial 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 assessing potential endpoints such as body weight and HbA1c
• TERN-601 is a Terns’ proprietary orally-administered small-molecule glucagon-like peptide-1 receptor (GLP-1R) agonist for the treatment of obesity
  • Terns screened more than 20,000 molecular permutations through its proprietary quantitative structure activity relationship (QSAR) model to identify suitable small-molecule scaffolds with potentially improved properties relative to other GLP-1-based approaches
  • 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

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

• In July 2022, Terns initiated dosing in the DUET Phase 2a clinical trial of TERN-501 (THR-β agonist) alone and in combination with TERN-101 (FXR agonist) in approximately 140 adult patients with presumed NASH (NCT05415722)
  • Primary endpoint is the relative change from baseline in liver fat content as measured by 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 cT1 (TERN-501 monotherapy vs. placebo as well as 501+101 combination vs. placebo)
• Top-line data expected in the second half of 2023

Key Appointments

• Radhika Tripuraneni, M.D., M.P.H. joined the Company’s Board of Directors in July 2022. Dr. Tripuraneni serves as the Chief Development Officer of Prothena Corporation plc and brings to the Terns Board of Directors more than 15 years of experience in drug development
• Kerry Russell, M.D., Ph.D. joined the Company as Chief Medical Officer in June 2022. Dr. Russell was most recently vice president of late clinical development at Dicerna Pharmaceuticals, Inc. and was previously an associate professor at Yale University School of Medicine for over 13 years
