Trial Activity: Declining
Gastrointestinal Approved 2012-12-31

Mytesi is an antidiarrheal that helps adult patients living with HIV or AIDS who experience non-infectious diarrhea while taking anti-retroviral therapy. It is used to provide relief from the symptoms of this condition. This medication is specifically prescribed for those whose diarrhea is not caused by an infection but is associated with their ongoing HIV treatment regimen.

How MYTESI Works

This drug works by blocking specific chloride ion channels, known as CFTR and CaCC, located in the lining of the intestines. By inhibiting these channels, it prevents the excessive secretion of chloride and the high volume of water loss that occurs during diarrhea. This process helps normalize the flow of water and electrolytes through the gastrointestinal tract.

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
