XOFIGO (radium ra-223 dichloride)

Trial Activity: Declining
Oncology Approved 2013-05-15

Xofigo is a radioactive therapy used for patients with prostate cancer that has become resistant to medical or surgical treatments that lower testosterone. It helps patients who have developed symptomatic cancer spread in their bones but do not have evidence of the disease in their internal organs. This medication is specifically used to target and manage these painful bone metastases.

How XOFIGO Works

This drug works by mimicking calcium to target areas of high bone turnover where cancer is present. Once it binds to the bone mineral, it releases alpha particles that cause double-strand DNA breaks in nearby tumor cells and bone-regulating cells. Because these particles have a very short range, the treatment focuses its energy on the cancer while limiting damage to healthy surrounding tissue.

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
