VEGFR Inhibitors
2 drugsAbout VEGFR
Vascular Endothelial Growth Factor Receptor (VEGFR) is crucial for angiogenesis, the formation of new blood vessels, playing a significant role in development and disease.
Human genetic studies provide strong validation for VEGFR (KDR) as a therapeutic target (max score 0.92), with variants linked to endometriosis and female infertility. Loss-of-function variants are protective, suggesting inhibition is likely beneficial.
VEGFR is targeted by 2 approved small molecule drugs: CAPRELSA (Sanofi) and ICLUSIG (Takeda), primarily in 'other' therapeutic areas.

Human Genetic Evidence Strong
Strong genetic evidence supports VEGFR as a drug target with a max score of 0.92.
Strong genetic support increases clinical success probability, especially for endometriosis indications.
💡 Why inhibition?
- • Loss-of-function variants reduce disease risk (OR < 1)
- • 100% directional consistency across 1 traits
- • Strong signal in reproductive system or breast disease pathways

Understanding these scores
Association Score (0-1): Combines all evidence types (genetic, literature, drugs, animal models). Higher = more evidence linking target to disease. This is a ranking heuristic, not a confidence score.
L2G Score: Open Targets uses a machine learning model (Locus-to-Gene) to predict which gene is causal at each GWAS locus. L2G=0.5 means ~50% probability of being the causal gene. Only associations with L2G > 0.05 are included.
Odds Ratio (OR): From gene burden studies (UK Biobank, AstraZeneca PheWAS). Measures how loss-of-function variants affect disease risk. OR<1 = protective (inhibiting target may help), OR>1 = risk (losing function causes disease).
Beta (β): Effect size for continuous traits. β<0 = protective, β>0 = risk.
Clinical Translation (~1.8x): Based on Nelson et al. 2015: drug targets with genetic evidence have ~2x higher success rates in clinical trials. We estimate: Strong support (score ≥0.7) → ~1.8x, Moderate (0.3-0.7) → ~1.3x, Weak → baseline.
Colocalization (H4): Tests whether a GWAS signal and an eQTL/pQTL signal share the same causal variant. H4 is the posterior probability that both traits are associated AND share a causal variant. H4 > 0.8 = strong evidence that gene expression/protein levels drive disease risk. This links genetic variation → gene expression → disease, supporting the target-disease connection.
Top Drugs
Sanofi and Takeda are the only companies with approved VEGFR-targeting drugs.
The market is not highly concentrated, suggesting opportunities for new entrants with differentiated VEGFR inhibitors.

Routes of Administration
VEGFR is amenable to small molecule drugs, with oral options available for convenient dosing.
Explore non-small molecule modalities like antibodies or fusion proteins to differentiate from existing therapies.

How We Calculate These Metrics
Target Attractiveness Score
A 0-100 score based on trial activity, sponsor diversity, and completion rates. Calculated from 47 clinical trials targeting VEGFR.
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
