ICH HARMONISED TRIPARTITE GUIDELINE ... development of a proper long-term stability program becomes critical to the successful development of a commercial product. Thermal analytical techniques for stability testing (DSC,microcalorimetry) Overview of ICH guideline for stability testing Stability Q1A (R2) Stability Testing in New Drugs and Products (Revised guideline) Q1B Photo-Stability … Zone IVa. 21ºC ± 2ºC . Formal, long-term stability testing is still required as per the ICH guidelines, but these early predictive tests can help establish a high degree of confidence that the compound (drug substance form and formulation) will have long-term stability. The purpose of this document is to give guidance to applicants regarding the type of stability studies that should be provided in support of marketing applications.

Climatic Zone. intermediate (if necessary) and long-term testing, Proposed storage statement and shelf-life. Below are the general ICH storage conditions.

12 Months.

stability requirements for climatic zones i and ii are well established and defined in ich guidelines q1a, stability requirements for climatic zones iii and iv are not properly outlined due to divergences in its stability requirements so no global harmonization on long term conditions was reached.

Drug Substance / Drug Product 16 Stability Commitment When available long term stability data on primary batches do not cover the proposed re-test or shelf life granted at the time of approval from at least three production batches, a commitment should be made to continue the stability studies post approval in order to firmly establish the re-test shelf life (ICH Q1E).

Humidity.

The parent guideline states that regression

ICH stability guidelines give storage conditions and times for long-term, intermediate, and accelerated stability studies.

Minimum Duration. Zone II. 60% RH ± 5% RH.

You may wish to consider longer time points for long-term stability testing (i.e., 36, 48, 60 months) if you feel your product can achieve a longer shelf life.

Stability testing (according to ICH Q1A) and photostability testing (according to ICH Q1B) in the pharmaceutical industry, long-term storage, conditioning and climate testing of plastic material/metal/composite material, storage of electronic components/lacquers/coatings in controlled environment CONSTANT CLIMATE CHAMBER HPP PAGE 4 TO 5 TECHNICAL DATA PAGE 6 TO 7 Stability … ICH Guidelines recommend that proposed stability testing should show results after 0, 3, 6, 9, 12, 18 and 24 months storage for long-term testing and 0, 3 and 6 months storage for accelerated testing. 35% RH ± 5% RH.

The purpose of this document is to give guidance to applicants regarding the type of stability studies that should be provided in support of marketing applications.

Following are ICH stability conditions for these zones. ICH HARMONISED TRIPARTITE GUIDELINE ... development of a proper long-term stability program becomes critical to the successful development of a commercial product.

Long Term Stability Testing Conditions. the stability study under the long-term storage condition” (hereafter referred to as long-term data). Recent development in ICH Guidelines The Guideline "Evaluation of Stability Data" describes when and how an extrapolation of the data can be undertaken in order to establish the re-test period for a drug substance or the shelf life for a drug product beyond the observed range itself, based on the data resulting from the long-term stability testing.
