Cross-source evidence suggests BTK inhibitor hepatotoxicity signal across clinical trials

Abstract

Analysis of 6 finding(s) across 4 source(s) reveals converging evidence on BTK inhibitor hepatotoxicity signal across clinical trials.

Key finding: {'success': False, 'error': 'FDA API error: 404 Not Found', 'code': 'FDA_404', 'requestId': '0d0930d9-81d3-4305-b511-75623a41ad65'}.

Evidence spans chembl_drug_search, ema_search, fda_lookup, opentargets_search, strengthening the cross-source signal.

Evidence

fda_lookup

• {'success': False, 'error': 'FDA API error: 404 Not Found', 'code': 'FDA_404', 'requestId': '0d0930d9-81d3-4305-b511-75623a41ad65'}

chembl_drug_search

• {'molecule_chembl_id': 'CHEMBL3301625', 'pref_name': 'SPEBRUTINIB', 'max_phase': '2.0', 'molecule_type': 'Small molecule', 'first_approval': None}
• {'molecule_chembl_id': 'CHEMBL4297549', 'pref_name': 'HUMAN C1-ESTERASE INHIBITOR', 'max_phase': '4.0', 'molecule_type': 'Protein', 'first_approval': 2011}
• {'molecule_chembl_id': 'CHEMBL4297879', 'pref_name': '.ALPHA.1-PROTEINASE INHIBITOR HUMAN', 'max_phase': '4.0', 'molecule_type': 'Protein', 'first_approval': 2015}

ema_search

• {'total_count': 0, 'results': [], 'source': 'EMA Medicines Database', 'source_url': 'https://www.ema.europa.eu/en/documents/report/medicines-output-medicines_json-report_en.json', 'last_updated': '2026-03-07T22:50:28.060Z'}

opentargets_search

• {'data': {'search': {'hits': [], 'total': 0}}}

Testable Predictions

1. Prediction: Further cross-source correlation may clarify whether observed signals represent a causal relationship or confounding

Limitations

• Limitation (chembl_drug_search): Data from chembl_drug_search may have unknown biases
• Limitation (ema_search): Data from ema_search may have unknown biases
• Limitation (fda_lookup): FAERS data reflects voluntary reporting; reporting rates vary by drug age and media attention
• Limitation (opentargets_search): Data from opentargets_search may have unknown biases
