Best-Effort Research Profile

TERN-601 was an investigational oral small-molecule GLP-1 receptor agonist evaluated in Phase 1 and Phase 2 clinical studies in adults with overweight or obesity. Clinical studies reported GLP-1-consistent pharmacodynamic effects, including reduced appetite and delayed gastric emptying, together with dose-dependent weight loss. Terns Pharmaceuticals announced in October 2025 that it would not advance TERN-601 after Phase 2 findings, including treatment discontinuations related to adverse events and liver-enzyme elevations.

Source review pending. This descriptive profile is shown from the available source material as a best-effort educational reference. It has not passed the full verification bar and is not a dosing instruction, medical claim, or treatment recommendation.

Research Profile

Half-Life
Terminal elimination half-life reported as approximately 3–5 hours at doses above 100 mg; prolonged absorption supported sustained target coverage for approximately 16–24 hours and once-daily dosing in the reported pharmacokinetic analysis.
Administration Routes (Research)
oral

Reported Research Effects

Data source: Primary literature, regulator records, trial registries, and identity-specific evidence search

Reflects preclinical/research literature context only. Not a medical claim, dosing instruction, or treatment recommendation.

Research Notes

Clinical study regimens included once-daily oral administration. In the Phase 2 FALCON study, reported dose groups included 250 mg, 500 mg with slower titration, 500 mg, and 750 mg, administered over 12 weeks. These are historical research-study regimens and are not prescribing or administration recommendations. TERN-601 development was discontinued and the compound is not an approved medicine.

Supplementary research context only. Not medical advice or a treatment recommendation.

Registry Identifiers

Development code: TERN-601. Publicly reviewed authoritative sources did not provide a CAS Registry Number, chemical name, molecular formula, molecular weight, SMILES, InChI, or other structure-based identifier.

Source-Backed Observations

The Phase 2 FALCON study was a randomized, double-blind, placebo-controlled study of orally administered TERN-601 in adults with overweight or obesity. The study enrolled 167 participants and was completed in September 2025. Publicly reported Phase 2 results included maximum placebo-adjusted weight loss of 4.6% at Week 12; asymptomatic, reversible grade 3 liver-enzyme elevations occurred in three participants during post-treatment follow-up, with two considered drug-related.
