Hinova Pharmaceuticals Reports Positive Phase IIa Data for HP515 in MASH – THR-β Agonist Achieves >50% Liver Fat Reduction

Hinova Pharmaceuticals Inc. (SHA: 688302) announced that final analysis results from the Phase IIa clinical trial of HP515, a Class 1 innovative drug independently developed by the company for the treatment of metabolic dysfunction-associated steatohepatitis (MASH), have met the primary endpoint and key secondary endpoints with high statistical significance.

Clinical Trial Overview

ItemDetail
DrugHP515 – oral, highly selective THR-β agonist
DeveloperHinova Pharmaceuticals Inc. (SHA: 688302)
IndicationMetabolic dysfunction-associated steatohepatitis (MASH)
Study DesignPhase IIa, randomized, placebo-controlled
Treatment Duration12 weeks, once-daily oral administration
Dose Groups40 mg, 50 mg, 60 mg

Primary Endpoint Results – Liver Fat Content Reduction

GroupMean LFC Reduction at 12 Weeksp-value vs Placebo
Placebo3.5%Reference
HP515 40 mg>50%<0.001
HP515 50 mg>50%<0.001
HP515 60 mg>50%<0.001

All three active dose groups achieved statistically significant liver fat content (LFC) reductions exceeding 50%, compared to only 3.5% in the placebo group (P<0.001).

Secondary Endpoint Results

LFC Response Rates

  • ≥30% LFC reduction: Significantly higher proportions in all active dose groups vs placebo (P<0.001)
  • ≥50% LFC reduction: Significantly higher proportions in all active dose groups vs placebo (P<0.001)

Lipid Profile Improvements (P<0.001 for all comparisons)

  • Low-density lipoprotein cholesterol (LDL-C): Significant reduction
  • Apolipoprotein B (ApoB): Significant reduction
  • Non-high-density lipoprotein cholesterol (nonHDL-C): Significant reduction
  • Total cholesterol (TC): Significant reduction
  • Triglycerides (TG): Significant reduction
  • Small dense LDL-C (sd-LDL-C): Significant reduction

Mechanism of Action & Innovation

  • Target: Thyroid hormone receptor beta subtype (THR-β)
  • Mechanism: Highly selective and potent THR-β agonist that directly activates downstream gene transcription
  • Therapeutic Effects:
  • Enhances hepatocyte lipid metabolism activity
  • Increases hepatic fat metabolism
  • Reduces lipotoxicity
  • Classification: Class 1 innovative drug (first-in-class in China)
  • Market Status: No THR-β targeting product approved for marketing in China as of announcement date

Market Impact & Strategic Significance

  • MASH Market Opportunity: Global MASH/NASH therapeutics market projected to reach USD 40+ billion by 2030, representing one of the largest unmet medical needs in hepatology
  • Competitive Landscape: Multiple companies pursuing THR-β agonists globally, including Madrigal’s resmetirom (approved in US); HP515 represents China’s first domestically developed candidate in this class
  • Therapeutic Advantage: Dual benefit of significant liver fat reduction coupled with comprehensive lipid profile improvements addresses both hepatic and cardiovascular risk factors
  • Commercial Potential: If approved, HP515 would fill a critical gap in China’s MASH treatment landscape and position Hinova as a leader in metabolic liver disease therapeutics

The robust Phase IIa data support rapid advancement to Phase III development, with all three dose levels demonstrating compelling efficacy and establishing a clear dose-response relationship.
