Metformin (Active Rescue)

AstraZeneca · Phase 3 active Small molecule ✓ Verified Jun 2026

Metformin (Active Rescue) is a Biguanide Small molecule drug developed by AstraZeneca. It is currently in Phase 3 development for Type 2 diabetes mellitus.

Metformin reduces hepatic glucose production and improves insulin sensitivity by activating AMP-activated protein kinase (AMPK).

Metformin is a small molecule used to treat conditions such as Type 2 Diabetes Mellitus and Atherosclerosis. It is typically administered in combination with other medications, such as Saxagliptin, and is available in a 500 mg dosage.

If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
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
    AstraZeneca 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

Metformin is a biguanide that primarily works by decreasing gluconeogenesis in the liver and improving peripheral glucose uptake and utilization. It activates AMPK, a key metabolic regulator, which enhances insulin sensitivity and reduces blood glucose levels without stimulating insulin secretion. The 'Active Rescue' designation likely refers to a formulation or combination strategy, though the core mechanism remains glucose homeostasis improvement.
