ACTOS (pioglitazone hydrochloride)

Trial Activity: Stable 1 active trials
Metabolic Approved 1999-07-15

ACTOS helps adults with type 2 diabetes manage their blood sugar levels when used alongside diet and exercise. It is used in various clinical settings, either as a standalone therapy or in combination with other medications. Because the drug relies on the body's own insulin to function, it is not used for patients with type 1 diabetes or diabetic ketoacidosis.

How ACTOS Works

This medication works by activating PPAR-gamma receptors in the liver, fat, and muscle tissue, which modulates the activity of genes involved in glucose and lipid metabolism. This process reduces insulin resistance, allowing the body to use its existing insulin more effectively to dispose of glucose. Consequently, the drug helps lower the amount of sugar produced by the liver and improves glucose uptake in peripheral tissues.

How We Calculate These Metrics

Trial Activity Stage

Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.

Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.

  • Growth: High proportion of early-phase trials (Phase 1/2), active development
  • Expansion: Significant Phase 3 activity, approaching or pursuing approvals
  • Mature: Substantial Phase 4 post-marketing studies
  • Stable: Mixed phase distribution, steady development
  • Declining: Low active trial ratio, reduced R&D investment
