About Dihydroorotate dehydrogenase

Dihydroorotate dehydrogenase (DHODH) is an enzyme essential for de novo pyrimidine synthesis, providing crucial building blocks for DNA and RNA. It catalyzes the fourth step in pyrimidine biosynthesis, making it vital for cell proliferation and function.

How We Calculate These Metrics

Target Attractiveness Score

A 0-100 score based on trial activity, sponsor diversity, and completion rates. Calculated from 39 clinical trials targeting Dihydroorotate dehydrogenase.

Completion rate: Percentage of trials that reached their planned endpoint. Trials terminated early, withdrawn, or suspended are not counted—these often indicate safety issues, lack of efficacy, or strategic pivots.

  • Highly Attractive (80+): High trial activity, many sponsors, strong completion rates
  • Attractive (60-79): Good trial activity and validation
  • Moderate (40-59): Moderate interest from sponsors
  • Low (under 40): Limited trial activity or validation concerns

Strategic Insights

Auto-generated insights based on trial analytics including competition intensity, white space opportunities, modality shifts, and failure patterns. We analyze trial sponsors, phases, indications, and outcomes.

Risk Signals

  • High Competition: Many sponsors competing for this target (may reduce market opportunity)
  • High Failure Risk: Low trial completion rates suggest development challenges
  • Low Validation: Limited trial activity or poor outcomes indicate uncertain viability
  • White Space Available: Underexplored indications present opportunities
