Clinical Trial Supply Write-Off — Study Termination
Writing off unused clinical trial drug supply when a clinical programme is discontinued.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| R&D Expense — Clinical Supply Write-Off | Expense (+) | 4,800,000.00 | - |
| Clinical Trial Supply Inventory | Asset (-) | - | 4,800,000.00 |
💡 Accountant's Note
When a clinical programme is terminated (safety concerns, efficacy failure, strategic decision), any remaining clinical trial supply is written off as R&D expense. The inventory has no alternative commercial use and cannot be sold. Disposal costs (incineration of controlled substances) are an additional charge.
Practitioner & Systems Framework
💻 ERP Architecture
Clinical trial supply is maintained in a separate inventory location in the ERP, segregated from commercial supply. When a programme is terminated, the clinical operations and supply chain teams generate a list of all remaining clinical supply lots globally (at clinical sites, investigational pharmacies, and central depots). The write-off is posted by lot number against the clinical inventory account. Disposal is managed per regulatory requirements — controlled substances require DEA-witnessed destruction. An inventory disposal certificate is obtained for each lot.
⚠️ Audit Flags
Auditors test the write-off inventory valuation against the clinical supply cost records. Confirm that all remaining lots across all clinical sites worldwide are identified and included in the write-off (sites with active supply can be overlooked). Test that destruction is properly managed and evidenced (disposal certificates). For programmes partially completed, assess whether any completed Phase II data has value as a potential future asset (out-licensing) — if so, the terminated programme's sunk cost is still expensed but potential licensing income may be disclosed as a contingent asset.
📄 Required Documentation
Programme termination decision documentation, global clinical supply inventory count at termination, write-off calculation by lot, destruction certificates per lot and per site, DEA destruction records (for controlled substances), R&D expense classification journal, and financial statement disclosure of the terminated programme.
