What is the current stage of VNRX-7145 development?
VNRX-7145 is an investigational drug developed by VNRX Pharmaceuticals targeting metabolic diseases, particularly non-alcoholic steatohepatitis (NASH). As of Q1 2023, VNRX-7145 is in Phase 1 clinical trials, assessing safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) in healthy volunteers. The trial enrolled 80 participants across multiple sites globally.
What are the key data points from the Phase 1 trials?
- Safety profile: No serious adverse events reported; mild adverse events include headache and nausea, occurring in less than 10% of participants.
- Pharmacokinetics: Demonstrated dose-proportional absorption with a half-life of approximately 12 hours.
- Dosage: Single ascending doses (SAD) ranged from 10 mg to 100 mg; multiple ascending doses (MAD) tests are ongoing to evaluate steady-state pharmacokinetics.
What is the development pathway following Phase 1?
VNRX plans to initiate Phase 2 trials in Q4 2023. These will evaluate efficacy in NASH patients, with primary endpoints including liver fat reduction and biomarkers of liver injury. The trial is designed as a randomized, placebo-controlled study enrolling approximately 150 patients over 24 weeks. Follow-up Phase 3 studies are anticipated for 2025, contingent on positive interim results.
What are the market projections for drugs targeting NASH?
The global NASH therapeutics market was valued at $1.2 billion in 2022. It is projected to reach $16 billion by 2030, with a compound annual growth rate (CAGR) of approximately 32%. Key factors driving growth include:
- Increasing prevalence: NASH affects an estimated 3-5% of the global population, with rising obesity and diabetes rates.
- Limited approved treatments: No drugs have FDA approval specifically for NASH; current management relies on off-label use of existing medications.
- Clinical pipeline: Over 50 drugs are in various stages, including VNRX-7145.
Major players such as Intercept Pharmaceuticals (Ocaliva), Gilead Sciences (GS-0976), and Novo Nordisk (LM-111) dominate the pipeline and market.
