Global Clinical Landscape & Future Outlook

The race for GPBAR1 (TGR5) therapeutics is intensifying, with major players shifting focus from systemic agonists to intestine-restricted and biased modalities. First-generation pan-agonists (e.g., INT-777) demonstrated efficacy in NASH and Type 2 Diabetes but encountered gallbladder-related safety limitations (pruritus, gallbladder filling). The next wave of R&D is targeting pathway-biased signaling (cAMP vs β-arrestin) to preserve metabolic benefits while minimizing off-target effects. The convergence of TGR5 agonism with GLP-1R co-agonism represents a critical frontier for combination metabolic therapy.
