Continued Process Verification in Pharma: Real-Time Monitoring, Trending & Lifecycle Stage 3 Compliance Continued Process Verification in Pharma: Real-Time Monitoring, Trending & Lifecycle Stage 3 Compliance 1. Introduction to Continued Process Verification (CPV) Continued Process Verification (CPV) represents the third stage in the pharmaceutical process validation lifecycle, focusing on ongoing process monitoring to ensure sustained product quality. While Stage 1 (Process Design) and Stage 2 (Process Qualification) confirm that a process works as intended, Stage 3—CPV—ensures that it keeps working consistently throughout commercial production. Defined in the FDA’s 2011 guidance “Process Validation: General Principles and Practices,” CPV is a requirement…

CPV Data Strategy: Parameters, Sampling Plans & Trending Tools Building a Robust CPV Data Strategy: From Parameters to Trending Tools Stage 3 of the pharmaceutical process validation lifecycle — Continued Process Verification (CPV) — ensures that manufacturing processes remain in a state of control through ongoing monitoring. A well-designed CPV data strategy forms the backbone of compliance, efficiency, and product quality. This article explores how to create a scientifically sound data collection and analysis plan for CPV, covering parameter selection, sampling plans, trending tools, and regulatory expectations. 1. Regulatory Expectations for CPV Data Strategy Regulatory authorities expect a lifecycle approach…

Using Control Charts, Moving Averages & Trend Rules for CPV: Pharma Guide to Data-Driven Process Monitoring How to Use Control Charts, Moving Averages & Trend Rules in CPV for Effective Process Monitoring Continued Process Verification (CPV), the third stage in the pharmaceutical process validation lifecycle, emphasizes ongoing monitoring of critical parameters to maintain a state of control. A core element of CPV is statistical trending, which involves the use of control charts, moving averages, and trend rules. These tools help identify early signs of variability, drift, or out-of-trend performance, enabling proactive corrective action. In this article, we break down how…

Trending Deviations and Out-of-Trend (OOT) Events Trending Deviations and Out-of-Trend Events in CPV: Detection, Investigation & Regulatory Compliance In the context of Continued Process Verification (CPV), managing variability is not limited to individual out-of-specification (OOS) results. Trending deviations and Out-of-Trend (OOT) events provide early warnings of potential process drift, long before failure occurs. Identifying, evaluating, and reacting to these trends are essential for maintaining control and ensuring regulatory compliance. This article explores how pharma manufacturers should handle OOTs, trending deviations, and signal detection under a robust CPV framework, including documentation, investigation strategies, and corrective action plans (CAPA). 1. Defining Out-of-Trend…

Writing the CPV Plan & Report According to FDA/ICH Guidelines: Templates, Content & Review Strategy How to Write a CPV Plan & Report as per FDA and ICH Guidelines Stage 3 of pharmaceutical process validation—Continued Process Verification (CPV)—requires robust documentation to ensure lifecycle control of commercial manufacturing. The CPV Plan and CPV Report are the two foundational documents that define how the process will be monitored and how data trends are assessed. This article walks you through how to prepare, structure, and review CPV documentation in compliance with FDA, ICH, and EMA expectations. 1. What Is a CPV Plan? The…

How CPV Feeds into Change Control, Deviations & CAPA: Integration with QMS Integrating CPV with QMS: How Continued Process Verification Feeds into Change Control, Deviations, and CAPA Continued Process Verification (CPV), the third stage of the pharmaceutical process validation lifecycle, is more than just routine data monitoring—it’s the foundation for ongoing process improvement and quality decision-making. When executed properly, CPV becomes the nerve center of the Quality Management System (QMS), driving evidence-based change control, triggering deviation investigations, and informing Corrective and Preventive Actions (CAPA). This article explains how CPV feeds into QMS components like Change Control, Deviations, and CAPA, providing…
