CD80 Inhibitors
2 drugsAbout CD80
CD80 is a protein on immune cells that acts as a costimulatory molecule, modulating immune responses. It interacts with other molecules on immune cells to enhance or suppress their activity, which is vital for T cell activation.
CD80 is a therapeutic target with moderate genetic support (max score 0.65). Loss-of-function variants are protective against vitiligo (score 0.65) and systemic lupus erythematosus (score 0.56), suggesting inhibition may be beneficial.
Two FDA-approved drugs, ORENCIA and NULOJIX, target CD80 as fusion proteins. Both drugs are marketed by Bristol-Myers Squibb for indications beyond common therapeutic areas.
Strategic Insights
ℹ️ How we calculate- Validated target with strong trial activity and 80% attractiveness score.
- White space opportunity in Kidney Transplant with only 2 trials.
Human Genetic Evidence Moderate
Genetic evidence provides moderate support for CD80 as a drug target.
A score of 0.65 suggests CD80 is a viable target, but further validation may be needed.
💡 Why inhibition?
- • Loss-of-function variants reduce disease risk (OR < 1)
- • 100% directional consistency across 2 traits
- • Strong signal in immune system disease, integumentary system disease pathways

max H4: 1.00eQTL/pQTL signals for CD80 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.
Top Drugs
Bristol-Myers Squibb is the only company with approved drugs targeting CD80.
The lack of competitors suggests high barriers to entry or untapped market potential.
Drug Modality Landscape
Modalities
Routes of Administration
CD80 requires biologic approaches (fusion protein), likely due to its structure or location.
Exploring alternative modalities like antibodies or small molecules could provide a competitive advantage.

How We Calculate These Metrics
Target Attractiveness Score
A 0-100 score based on trial activity, sponsor diversity, and completion rates. Calculated from 118 clinical trials targeting CD80.
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
