About PDE3

Phosphodiesterase 3 (PDE3) is an enzyme that regulates intracellular levels of cAMP and cGMP by hydrolyzing these cyclic nucleotides. This influences physiological processes like smooth muscle contraction, platelet aggregation, and cardiac function.

How We Calculate These Metrics

Target Attractiveness Score

A 0-100 score based on trial activity, sponsor diversity, and completion rates. Calculated from 20 clinical trials targeting PDE3.

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 Trials terminated early, withdrawn, or suspended are not counted—these often indicate safety issues, lack of efficacy, or strategic pivots.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
