FOSTER CITY, Calif., Sept. 09, 2024 (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, today announced positive top-line data from its Phase 1 randomized, double-blind, placebo-controlled single and multiple-ascending dose (SAD and MAD) trial to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of TERN-601 dosed once-daily (QD) in healthy adults with obesity or overweight.
The clinical trial results showed TERN-601 was well tolerated and demonstrated dose-dependent, statistically significant placebo-adjusted mean weight loss across all three doses evaluated in the 28-day MAD study, with maximum placebo-adjusted mean weight loss of 4.9% (p<0.0001) at the highest dose of 740 mg QD. Additionally, 67% of participants lost 5% or more of their baseline body weight at the top dose.
“These compelling results underscore TERN-601’s potential to be a class-leading GLP-1R agonist based on its composite profile of initial indications of efficacy, tolerability and manufacturing scalability,” said Amy Burroughs, chief executive officer of Terns. “These data validate the potential of TERN-601 for the treatment of obesity as monotherapy or in combination with agents such as TERN-501, our internally discovered, clinical stage THR-β agonist, or a GIPR modulator from our TERN-800 series. With operational preparations well underway, we look forward to swiftly advancing this promising product candidate into Phase 2 clinical development in 2025.”
“We are delighted to demonstrate potent GLP-1R agonism with TERN-601 as its distinct drug properties allowed for sustained target coverage with once-daily dosing and the evaluation of doses up to 740 mg, while being tolerable,” noted Emil Kuriakose, chief medical officer of Terns. “Importantly, we believe we have successfully identified an optimal range of clinically active, well tolerated doses to take forward in Phase 2 clinical trials, with no new dose range exploration anticipated.”
About the TERN-601 Phase 1 Trial
The Phase 1 trial was a randomized, double-blind, placebo-controlled single and multiple-ascending dose (SAD and MAD) trial to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of TERN-601 in healthy adults with obesity or overweight. The trial consisted of two parts.
Part 1 (SAD) was a single ascending dose study that evaluated five TERN-601 dose levels in healthy participants with a Body Mass Index (BMI) of ≥ 25 kg/m2 and < 40 kg/m2. The starting TERN-601 dose was 30 mg, with subsequent dose levels based on review of emerging safety and PK data from prior cohorts.
In Part 2 (MAD) of the trial, obese and overweight healthy adults were enrolled in cohorts that included titration of TERN-601 administered for 28 days at doses selected based on data from Part 1 (SAD). Part 2 included healthy participants with a BMI of ≥ 27 kg/m2 to < 40 kg/m2.
The primary endpoint of the trial was to evaluate safety and tolerability of TERN-601 administered once-daily for 28 days. Secondary endpoints included PK, efficacy as measured by body weight loss following 28 days of treatment with TERN-601, and other exploratory markers.
About TERN-601
TERN-601 is an oral, small-molecule glucagon-like peptide-1 receptor agonist, or GLP-1R agonist, internally discovered at Terns for development in obesity. TERN-601 was designed through internal structure-based drug discovery efforts employing Terns’ proprietary three-dimensional QSAR model of the receptor. The ligands were further optimized based on in vitro activity, metabolic stability, and pharmacokinetic parameters. This process led to the selection of TERN-601, a potent GLP-1R agonist biased towards cAMP generation.
