Inspection Approach

How Pratik Inspects

Upadhyay is one of FDA's most prolific investigators, with a 483 issuance rate that reflects an uncompromising approach to CGMP compliance. His first-day facility walkthrough is critical to his methodology — at Intas Pharmaceuticals, investigators found a truck loaded with bags of shredded cGMP documents on Day 1, and at Granules India, bird intrusion, dust contamination, and torn records in waste bags were identified during the initial physical assessment.

His signature approach involves deep-dive investigations into OOS results, tracing root cause analyses through multiple layers: interviewing analysts, reviewing chromatographic raw data, and checking whether investigations were extended to other batches and products. At Torrent Pharmaceuticals, he identified that efficacy complaints were not being logged and OOS investigations lacked scientific rigour, leading to a September 2024 warning letter.

Upadhyay is particularly effective at detecting data destruction and falsification. He specifically checks waste disposal areas, waste bags, and uncontrolled paper for evidence of data integrity failures. When issues are found with a single analyst, he demands investigation extension to all work performed by that analyst — a pattern that has turned single findings into facility-wide data integrity crises at multiple Indian manufacturing sites.

Pre-Inspection Preparation

How to Prepare

  • 1 Audit waste management areas before any inspection — Upadhyay has found torn cGMP records in waste bags at multiple facilities. Ensure all document destruction follows SOPs with documented evidence.
  • 2 Review all OOS investigations for scientific soundness — his citations consistently focus on whether root cause conclusions are supported by data and whether investigations extend to related batches.
  • 3 Validate cleaning procedures end-to-end — he rejects MACO-based carryover limits when the underlying cleaning process itself is not validated.
  • 4 Ensure facility maintenance is current — physical conditions (walls, HEPA filters, pest control, floor integrity) are inspected during early walkthroughs.
  • 5 Verify analyst training and practices through direct observation — he interviews QC analysts and cross-checks documented work against actual practices.
  • 6 Extend investigations to all affected analysts and products when any data integrity issue is found — expect a demand for comprehensive scope.
  • 7 Confirm Field Alert Report compliance — review your FAR SOP and ensure substantiated complaints trigger timely filings within 3 working days.
  • 8 Prepare computer system audit trails for review — he examines chromatographic data integrity, interrupted sequences, and "Project Integrity Failed" messages.
  • 9 Ensure environmental monitoring data is accurate — at Intas, he found that plate counts were systematically under-reported.
  • 10 Maintain controlled document practices — no data recording on uncontrolled paper. All raw data must be on pre-numbered, controlled forms.
  • 11 Review complaint handling processes — he checks whether product quality complaints are properly categorised and Health Hazard Evaluations conducted.
  • 12 Document equipment qualification status — every piece of analytical equipment should have current qualification records accessible during inspection.
