Terns Pharmaceuticals' trial data from its oral GLP-1 treatment for obesity missed a high threshold for efficacy, safety and tolerability.
The biopharmaceutical company said Tuesday it will not advance the therapy, or make any further metabolic disease investments.
"The threshold for a truly differentiated oral GLP-1RA therapy -- one that delivers safety, tolerability and efficacy -- is high," Chief Executive Amy Burroughs said.
The treatment's recent Phase 2 topline 12-week results did not meet this threshold, Burroughs added.
The results showed a maximum placebo-adjusted weight loss of 4.6%. About 12% of patients discontinued treatment due to adverse events, the majority of which were gastrointestinal related, the company said.
Asymptomatic, reversible grade 3 liver enzyme elevations occurred in three participants during a post-treatment follow-up period, two of which were drug related, the company said.
Shares slid 13% to $7.10 in after-hours trading. The stock is up 47% this year through the market close.
