FOSTER CITY, CA, USA I March 21, 2022 I Terns Pharmaceuticals, Inc. (“Terns” or the “Company”) (Nasdaq: TERN), a clinical-stage biopharmaceutical company developing a portfolio of small-molecule single-agent and combination therapy candidates to address serious diseases such as non-alcoholic steatohepatitis (NASH) and obesity, today reported top-line results from Part 1 of the Company’s Phase 1b AVIATION Trial of TERN-201, a vascular adhesion protein-1 (VAP-1) inhibitor in development for the treatment of patients with NASH.  

Part 1 of the AVIATION Trial met the primary safety endpoint. Compared to placebo, TERN-201 10 mg administered for 12 weeks to presumed NASH patients was generally well-tolerated with a similar incidence of adverse events (AEs) between the 10 mg treatment group and placebo. All AEs were mild to moderate. There were no treatment-emergent serious AEs (SAEs), including no cases of treatment-related monoamine oxidase inhibition (e.g., central nervous system toxicity), and no patients discontinued TERN-201 or the study due to any AE. While treatment with TERN-201 10 mg resulted in near complete (>98%) inhibition of plasma VAP-1 in most subjects, there were no meaningful changes in exploratory serum or imaging NASH biomarkers with TERN-201 10 mg relative to placebo, including corrected T1 (cT1), a measure of inflammation and fibrosis linked to clinical outcomes, as well as ALT, AST, GGT and CK-18.

Part 2 of the AVIATION Trial assessing 20 mg of TERN-201 remains ongoing, with top-line results expected in the second half of 2022. Terns will continue to analyze results from Part 1 of the AVIATION Trial to evaluate next steps for the TERN-201 program.

“We want to thank the patients, study teams and physicians who participated in the well-executed Part 1 of the AVIATION Trial,” said Erin Quirk, M.D., President, Chief Medical Officer and Head of R&D at Terns. “While the AVIATION results from Part 1 were disappointing, Terns is fortunate to have a broad pipeline, cash runway expected to fund operations into 2024 and a stellar team to support our pipeline activities. We look forward to the planned initiation of our Phase 2a trial of TERN-501 alone and in combination with TERN-101 for NASH in the first half of 2022 and our Phase 1 trial of TERN-601, an oral small-molecule GLP-1 receptor agonist for obesity, in 2023.”

About the AVIATION Trial
The AVIATION Trial (NCT04897594) is a multi-center, randomized, double-blind, dose-ranging, placebo-controlled, proof of concept, adaptive, Phase 1b clinical trial. The primary objective of the AVIATION trial is to evaluate the safety and tolerability of TERN-201 over 12 weeks of treatment in patients with presumed non-cirrhotic NASH. Secondary objectives included pharmacokinetics and assessment of pharmacodynamic effect on VAP-1 activity. The clinical trial is designed to be conducted in two parts (Part 1 and Part 2). Part 1 of the AVIATION Trial evaluated 10 mg TERN-201 over 12 weeks with a four-week follow-up period. The patients in Part 1 were randomized to receive placebo (n=10) or 10 mg TERN-201 (n=20), and patients in Part 2 are randomized to receive placebo or 20 mg TERN-201.

About TERN-201
TERN-201 is a highly selective, irreversible, covalent inhibitor of vascular adhesion protein-1 (VAP-1). VAP-1 is a transmembrane protein highly expressed in hepatic vascular endothelial cells that binds to proteins on the surface of white blood cells to facilitate their deceleration, binding and transmigration from the blood stream into the liver. VAP-1 has been shown to be over-expressed in the livers of patients with NASH and fibrosis. In Terns’ Phase 1 first-in-human (SAD/MAD) clinical trial across 61 healthy subjects, TERN-201 was shown to be well-tolerated and fully suppress the enzymatic activity of VAP-1 at all evaluated doses with suppression persisting up to seven days after a single dose. In preclinical studies, TERN-201 showed significant dose-dependent reductions in liver inflammation and fibrosis in a model of liver injury. TERN-201 exhibits high selectivity for VAP-1, enhanced liver distribution and minimal potential for off-target inhibition of monoamine oxidases (MAOs). Terns received Fast Track Designation from the FDA for TERN-201 for the treatment of NASH in August 2020. TERN-201 was in-licensed from Eli Lilly and Company in March 2018 pursuant to an exclusive, worldwide license agreement.
