  • Preclinical (rodent)
  • 16 weeks
  • No hepatotoxicity, nephrotoxicity, or cardiac dysfunction observed
  • 38% increased mitochondrial density, 22% reduced fasting glucose, 31% improved insulin sensitivity
  • Species differences in drug metabolism; 16 weeks in mice ≈ 3–4 years human equivalent, not lifetime exposure
  • Phase 1 (human)
  • 12 weeks
  • No serious adverse events; 5% mild liver enzyme elevation (resolved); 18% GI symptoms at high dose
  • Data pending full publication; preliminary reports show improved VO2 max and reduced HbA1c in prediabetic subgroup
  • Short duration; healthy volunteer population may not reflect patient populations with metabolic disease
  • Mechanistic concern
  • Theoretical
  • Chronic ERRα activation could theoretically impair mitophagy or deplete metabolic cofactors
  • Unknown. No long-term human data exists
  • Based on pathway biology, not observed effects; may or may not manifest clinically
  • Drug interaction risk
  • CYP3A4 substrate. Potential interactions with statins, immunosuppressants, antifungals
  • Unknown pending pharmacokinetic studies
  • Common concern with hepatically metabolised drugs; clinical significance depends on specific co-medications
