Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Big-pharma sponsor +3.0pp
    Eli Lilly and Company is a top-20 pharma sponsor — historical approval rates run ~3pp above average due to scale, regulatory experience, and trial-design quality.

Mechanism of action

Biguanides are a class of antidiabetic agents that work primarily by decreasing gluconeogenesis in the liver and improving peripheral glucose uptake and utilization. They activate AMPK, a key metabolic regulator, and inhibit mitochondrial respiratory chain complex I, leading to reduced ATP production and suppression of hepatic glucose output. This mechanism makes them effective for lowering blood glucose without stimulating insulin secretion.
