S1PR4 Inhibitors
3 drugsAbout S1PR4
S1PR4, or sphingosine-1-phosphate receptor 4, is a G protein-coupled receptor involved in modulating immune cell trafficking and inflammation. It functions as a receptor for sphingosine-1-phosphate, a bioactive lipid mediator.
Human genetic studies provide moderate support for S1PR4 as a therapeutic target, with variants linked to severe acute respiratory syndrome (score 0.55) and hypothyroidism (score 0.54). Colocalization analysis reveals 10 strong eQTL/pQTL signals, suggesting potential regulatory roles.
S1PR4 is targeted by 3 FDA-approved small molecule drugs, including GILENYA and TASCENSO ODT. These drugs are primarily used in the central nervous system, with some applications in other therapeutic areas.

S1PR4 Genetic Evidence Moderate
Genetic evidence offers moderate support for S1PR4, with a max score of 0.55.
Further investigation of high H4 colocalization signals may reveal novel therapeutic opportunities.
Evidence Across Diseases

max H4: 1.00eQTL/pQTL signals for S1PR4 colocalize with these GWAS traits, providing causal evidence that gene expression changes drive disease risk.
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.

How We Calculate These Metrics
Target Attractiveness Score
A 0-100 score based on trial activity, sponsor diversity, and completion rates. Calculated from 24 clinical trials targeting S1PR4.
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
