The proposed Phase I/II study will assess TGM-312 in healthy adult individuals and MASH patients, focusing on the pharmacodynamics, tolerability, safety, and pharmacokinetics.

Liver biopsies and exploratory imaging and biomarker endpoints will also be part of the MASH patient evaluations.

Subject to regulatory clearance, the trial is set to begin in early 2026 in the UK, with initial data expected in the second half of 2026.

Preclinical studies in the Gubra-Amylin NASH diet-induced obese mouse model demonstrated reductions in slowed fibrosis progression, NAFLD Activity Score, and decreased hepatic inflammation, both as a single agent and along with emerging and approved MASH therapies.
