ADEMPAS (riociguat)

Guanylate Cyclase Stimulators Trial Activity: Stable 3 active trials
Cardiovascular Approved 2013-10-08

Adempas treats adults with specific types of high blood pressure in the lungs, including pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension. It helps patients who have persistent symptoms after surgery for blood clots or those with conditions that cannot be treated surgically. This medication is used to improve a patient's ability to exercise and perform daily tasks while also helping to delay the worsening of their condition.

How ADEMPAS Works

This drug works by targeting an enzyme called soluble guanylate cyclase, which serves as the receptor for nitric oxide in the heart and lungs. It uses a dual approach to increase the production of a signaling molecule that triggers vasodilation and regulates vascular inflammation and fibrosis. By both sensitizing the enzyme to existing nitric oxide and stimulating it directly, the medication helps restore signaling pathways that are often impaired in pulmonary hypertension.

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
