CD38 Inhibitors
3 drugsAbout CD38
CD38, or Cyclic ADP Ribose Hydrolase, is an enzyme involved in various biological processes. It has emerged as a significant drug target, particularly in oncology, due to its role in cell signaling and immune regulation.
Human genetic studies provide strong support for CD38 as a therapeutic target (max score 0.76), with variants linked to Parkinson's disease (score 0.76) and other conditions. This genetic evidence strengthens the rationale for therapeutic intervention.
CD38 is targeted by 3 FDA-approved drugs, including DARZALEX, SARCLISA, and DARZALEX FASPRO, spanning biologics and antibodies. These drugs, developed by Johnson & Johnson and Sanofi, are primarily used in oncology.

ℹ️ How we calculate- Validated target with strong trial activity and 80% attractiveness score.
- White space opportunity in Amyloidosis with only 4 trials.
- phase1 represents biological uncertainty with 58% completion.
Human Genetic Evidence Strong
CD38 has strong genetic support with a maximum score of 0.76 linked to Parkinson's disease.
Strong genetic support suggests higher probability of clinical success, warranting further investment.

max H4: 1.00eQTL/pQTL signals for CD38 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
Johnson & Johnson and Sanofi are the primary companies with approved CD38-targeting drugs.
High market concentration suggests significant barriers to entry; consider partnership or novel approach.

How We Calculate These Metrics
Target Attractiveness Score
A 0-100 score based on trial activity, sponsor diversity, and completion rates. Calculated from 389 clinical trials targeting CD38.
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
