An extrapolation of stability data assumes that the same change pattern will continue to apply beyond the period covered by long-term data. The correctness of the assumed change pattern is critical when extrapolation is considered. When estimating a regression line or curve to fit the long-term data, the data themselves provide a chec In this work, both the planning of a stress stability study to obtain a correct stability prediction from a temperature extrapolation and the suitable data treatment to discern the reliability of the stability results are discussed. The study was focused on the early formulation step of a very stable drug, Mitonafide (antineoplastic agent), formulated in a parenteral solution and in tablets. Extrapolation is the practice of using a known data set to infer information about future data. Extrapolation to extend the retest period or shelf life beyond the period covered by long-term data can be proposed in the application, particularly if no significant change is observed at the accelerated condition. Whether extrapolation of stability data is appropriate depends on the exten An extrapolation of stability data assumes that the same change pattern will continue to apply beyond the period covered by long-term data. The correctness of the assumed change pattern is critical when extrapolation is considered. When estimating a regression line or curve to fit the long
A typical example of a stability study deviation is late testing of a stability timepoint condition. Quite often, this is due to an analytical instrument issue or an error during sample shipment to another party for testing Stability studies ensuring product quality, safety, and efficacy throughout the time period are considered as pre-requisite for the acceptance and approval of any pharmaceutical product. These studies are required to be conducted in a planned way following the rules issued by ICH, WHO, and or other agencies A stability study is a program of testing that is designed to provide evidence on how the quality of a drug substance or drug product varies with time under the influence of a variety of environmental factors.

Accelerated stability studies were applied on the basis of first-order degradation kinetics to determine the shelf-life of the drugs at different temperatures (45 - 70°C) and storage times (1. In a recently issued ICH Q1E guidance on evaluation of stability data of drug substances and products, the need to perform a statistical extrapolation of a shelf-life of a drug product or a retest period for a drug substance is based heavily on whether data exhibit a change-over-time and/or variability. However, this document suggests neither measures nor acceptance criteria of these two. This guideline describes when and how extrapolation can be considered when proposing a retest period for a drug substance or a shelf life for a drug product that extends beyond the period covered by available data from the stability study under the long-term storage condition. 1.3 Scope of the Guideline . This guideline addresses the evaluation of stability data that should be submitted.
