HighTide’s First NDA for Diabetes Drug HTD1801 Accepted by China’s NMPA (TipRanks) - "The NDA follows three multicenter, randomized, double-blind, controlled Phase III trials in which HTD1801 met primary and multiple secondary endpoints and improved glycemic control, lipid metabolism, inflammatory markers, and renal function. These findings position HTD1801 as a potential single therapy addressing multiple facets of the cardiovascular-kidney-metabolic spectrum, which, if successfully brought to market, could offer differentiated value to patients and healthcare systems and support the company’s long-term growth trajectory."

Berberine: A Negentropic Modulator for Multi-System Coordination. (PubMed, Int J Mol Sci) - "Combination strategies, such as pairing BBR with metformin, Sodium-Glucose Cotransporter 2 (SGLT2) inhibitors, and agents targeting the microbiome or inflammation, have shown enhanced efficacy and substantial translational potential. Berberine ursodeoxycholate (HTD1801), an ionic-salt derivative of BBR currently in Phase III trials and directly compared with dapagliflozin, exemplifies the therapeutic promise of such approaches. Within the hub-axis paradigm, BBR emerges as a systems-level modulator that recouples energy, immune, and microbial circuits to drive multi-organ remodeling."

Evidence of Kidney Benefit with HTD1801 in Patients with Mild Renal Impairment (KIDNEY WEEK 2025) - "Conclusion These data provide the first clinical evidence that a therapy may benefit patients with CKD by improving the eGFR trajectory and recovering kidney function from the earliest stages of CKD, distinguishing HTD1801from existing therapies. The findings suggest a potential disease-modifying effect, indicating that HTD1801 may improve the eGFR trajectory."

SYMPHONY-2 (HTD1801 as an add-on therapy to Metformin): (TradingView) - "At week 24, the reduction from baseline in HbA1c with HTD1801 (-1.2%) was superior to placebo. HbA1c reductions were sustained in patients who continued receiving HTD1801 (-1.1% at Week 52). Placebo patients who switched to HTD1801 saw a reduction in HbA1c of -1.2% at Week 52, also substantiating the double-blind phase findings."

HTD1801 Demonstrates Promising Potential for Histologic Improvements in MASH in Both a Preclinical and Phase 2 Study. (PubMed, Clin Mol Hepatol) - "Dose-dependent improvements were observed across biomarkers, with more HTD1801-treated patients achieving response criteria associated with improvements in the histologic features of MASH. These findings suggest that HTD1801 has strong potential to produce histological improvements in patients with MASH."

These data suggest HTD1801 can comprehensively address metabolic and cardiovascular risk factors beyond glycemic control. Further evaluation of HTD1801 continues in 3 Phase 3 studies of T2DM and a Phase 2b study of patients with MASH and T2DM/pre-diabetes."

EVALUATION OF EFFICACY OF BERBERINE URSODEOXYCHOLATE (HTD1801) COMPARED TO ONGOING USE OF GLP-1 RECEPTOR AGONISTS IN PATIENTS WITH MASH AND T2DM (AASLD 2024) - P2 | "This data suggests newly initiated HTD1801 provides greater benefit than ongoing GLP-1RA use. Utilization of GLP-1RA continues to grow and may be confounding in studies of MASH. This has resulted in their exclusion from some new studies of MASH which is unlikely to be reflective of real-world use."
