Statistical Justification for Sample Size

ABOUT ABOUT

Almost all manufacturing and development companies perform at least some process validation studies, but it is difficult to decide how many Lots to include in the study and how large the Sample per Lot should be.

This webinar provides a “statistical” justification and method for determining Sample Sizes, and a statistical justification for using only 3 Lots (which is the typical number, especially in industries regulated by the FDA).

Those justifications can then be documented in Protocols or regulatory submissions, or can be given to regulatory auditors who may ask for them during onsite audits at your company. Thus, this webinar is designed to help you avoid regulatory delays in product approvals and to prevent an auditor from issuing you a nonconformity.

This webinar does not address clinical trials, nor bulk-solution processes. It applies to unitized products such as pills, drug-filled syringes, medical devices, and components.

Areas Covered in the Session :

This webinar explains how to choose and justify a sample-size for Lots that are included in Process Validation studies. The statistical methods discussed during the webinar include the following:

Confidence intervals
Confidence / Reliability Calculations (for variables & attributes)

It then explains how to analyze those samples in such a way that they provide statistically valid final %Reliability for the production Process itself. One example is worked through completely.

Topics include:

Introduction:

Regulatory requirements
Basic concepts and vocabulary

Calculation of Sample Size to be taken from each Lot in the Validation study
Calculation of % Confidence and %Reliability ( = %-in-specification) for each Lot
Calculation of % confidence and %Reliability for the Production Process
Worked example (with all calculations)
Example summary “justification” statement
