Clinical trials
Moderate104K records
Terminated, withdrawn, and suspended clinical trials across all therapeutic areas, with intervention metadata and termination reasons.
- AACT / ClinicalTrials.gov · Public Domain · daily refresh
- EudraCT · Public Domain · weekly refresh
- Drugs@FDA · Public Domain · weekly refresh
e.g. “Terminated Phase 3 oncology trials in 2024”
Antibodies
Moderate3.6K records
Developability failures including aggregation, polyreactivity, expression, and immunogenicity. Plus terminated antibody trials.
Coverage note: Public-database coverage at the molecular level is thin by nature — most antibody developability data is proprietary. Enterprise tier supplementary materials extraction in progress.

- SAbDab · planned
- FLAb · per-study, mostly CC-BY · quarterly refresh
- OAS · planned
e.g. “Antibodies with polyreactivity failures against PD-1”
Peptides
Moderate18.8K records
Stability failures, oral bioavailability dead ends, immunogenicity issues, and proteolytic degradation for therapeutic peptides.
- THPdb · Academic-use · quarterly refresh
- PepLife · planned
- DrugBank peptide subset · planned
e.g. “Peptides with failed oral bioavailability”
PROTACs
Thin824 records
Ternary complex failures, failed degradation, hook effect, and cell permeability issues for targeted protein degraders.
Coverage note: PROTAC discipline is ~7 years old; public coverage reflects the field's youth. Enterprise tier supplementary materials extraction in progress.
- PROTAC-DB · CC-BY 4.0 · quarterly refresh
- PROTACpedia · Academic-use · manual export
e.g. “Failed PROTACs targeting BTK”
Oligonucleotides
Thin144 records
Target engagement failures, delivery issues, hepatotoxicity, and immunogenicity for antisense oligonucleotides, siRNAs, and related modalities.
Coverage note: Most ASO/siRNA failure data is proprietary or in patents. Public coverage is thin. Enterprise tier supplementary materials extraction in progress.
- AOBase · planned
