Drug target analysis

Approved (phase 4): 1 · Phase ≥3: 1 · Phased (≥1): 1 · Undrugged: 0

Druggability breadth: 1 of 1 evidence-associated genes (100%) have a ChEMBL target (buckets above are over the deeply-mined display cohort).

Genes with an approved drug

The molecule shown is one approved compound that hits the gene — not necessarily a drug of choice or one indicated for this disease.

No cohort gene has a CPIC/DPWG genotype-guided dosing guideline (PharmGKB).

Drug repurposing candidates

4 approved/phased drugs hit cohort targets but don’t yet appear in disease-level clinical trials. Target-inhibition rationale is strongest for cancer driver genes; a bioactivity hit is a screening signal, not a treatment claim.
