Objectives of the Guideline The following guideline is a revised version of the ICH Q1A guideline and defines the stability data package for a new drug sub

5、stance or drug product that is sufficient for a registration application within the three regions of the EC, Japan, and the United States. It does not seek necessarily to cover the testing for registration in or export to other areas of the world. The guideline seeks to exemplify the core stability

6、data package for new drug substances and products, but leaves sufficient flexibility to encompass the variety of different practical situations that may be encountered due to specific scientific considerations and characteristics of the materials being evaluated. Alternative approaches can be used w

7、hen there are scientifically justifiable reasons. 1.2. Scope of the Guideline The guideline addresses the information to be submitted in registration applications for new molecular entities and associated drug products. This guideline does not currently seek to cover the information to be submitted

8、for abbreviated or abridged applications, variations, clinical trial applications, etc. Specific details of the sampling and testing for particular dosage forms in their proposed container closures are not covered in this guideline. Further guidance on new dosage forms and on biotechnological/biolog

9、ical products can be found in ICH guidelines Q1C and Q5C, respectively.1.3. General Principles The purpose of stability testing is 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 such as temperature

10、, humidity, and light, and to establish a re-test period for the drug substance or a shelf life for the drug product and recommended storage conditions. The choice of test conditions defined in this guideline is based on an analysis of the effects of climatic conditions in the three regions of the E

11、C, Japan and the United States. The mean kinetic temperature in any part of the world can be derived from climatic data, and the world can be divided into four climatic zones, I-IV. This guideline addresses climatic zones I and II. The principle has been established that stability information genera

12、ted in any one of the three regions of the EC, Japan and the United States would be mutually acceptable to the other two regions, provided the information is consistent with this guideline and the labeling is in accord with national/regional requirements.2. GUIDELINES 2.1. Drug Substance 2.1.1. Gene

13、ral Information on the stability of the drug substance is an integral part of the systematic approach to stability evaluation. 2.1.2. Stress TestingStress testing of the drug substance can help identify the likely degradation products, which can in turn help establish the degradation pathways and th

14、e intrinsic stability of the molecule and validate the stability indicating power of the analytical procedures used. The nature of the stress testing will depend on the individual drug substance and the type of drug product involved. Stress testing is likely to be carried out on a single batch of th

15、e drug substance. It should include the effect of temperatures (in 10C increments (e.g., 50C, 60C, etc.) above that for accelerated testing), humidity (e.g., 75% RH or greater) where appropriate, oxidation, and photolysis on the drug substance. The testing should also evaluate the susceptibility of

16、the drug substance to hydrolysis across a wide range of pH values when in solution or suspension. Photostability testing should be an integral part of stress testing. The standard conditions for photostability testing are described in ICH Q1B. Examining degradation products under stress conditions i

17、s useful in establishing degradation pathways and developing and validating suitable analytical procedures. However, it may not be necessary to examine specifically for certain degradation products if it has been demonstrated that they are not formed under accelerated or long term storage conditions

18、. Results from these studies will form an integral part of the information provided to regulatory authorities.2.1.3. Selection of Batches Data from formal stability studies should be provided on at least three primary batches of the drug substance. The batches should be manufactured to a minimum of

19、pilot scale by the same synthetic route as, and using a method of manufacture and procedure that simulates the final process to be used for, production batches. The overall quality of the batches of drug substance placed on formal stability studies should be representative of the quality of the mate

20、rial to be made on a production scale. Other supporting data can be provided.2.1.4. Container Closure System The stability studies should be conducted on the drug substance packaged in a container closure system that is the same as or simulates the packaging proposed for storage and distribution. 2.

21、1.5. Specification Specification, which is a list of tests, reference to analytical procedures, and proposed acceptance criteria, is addressed in ICH Q6A and Q6B. In addition, specification for degradation products in a drug substance is discussed in Q3A. Stability studies should include testing of

22、those attributes of the drug substance that are susceptible to change during storage and are likely to influence quality, safety, and/or efficacy. The testing should cover, as appropriate, the physical, chemical, biological, and microbiological attributes. Validated stability-indicating analytical p

23、rocedures should be applied. Whether and to what extent replication should be performed will depend on the results from validation studies.2.1.6. Testing Frequency For long term studies, frequency of testing should be sufficient to establish the stability pro the drug substance. For drug substances

24、with a proposed re-test period of at least 12 months, the frequency of testing at the long term storage condition should normally be every 3 months over the first year, every 6 months over the second year, and annually thereafter through the proposed re-test period. At the accelerated storage condit

25、ion, a minimum of three time points, including the initial and final time points (e.g., 0, 3, and 6 months), from a 6-month study is recommended. Where an expectation (based on development experience) exists that results from accelerated studies are likely to approach significant change criteria, in

26、creased testing should be conducted either by adding samples at the final time point or by including a fourth time point in the study design. When testing at the intermediate storage condition is called for as a result of significant change at the accelerated storage condition, a minimum of four tim

27、e points, including the initial and final time points (e.g., 0, 6, 9, 12 months), from a 12-month study is recommended.2.1.7. Storage Conditions In general, a drug substance should be evaluated under storage conditions (with appropriate tolerances) that test its thermal stability and, if applicable,

28、 its sensitivity to moisture. The storage conditions and the lengths of studies chosen should be sufficient to cover storage, shipment, and subsequent use. The long term testing should cover a minimum of 12 months duration on at least three primary batches at the time of submission and should be con

29、tinued for a period of time sufficient to cover the proposed re-test period. Additional data accumulated during the assessment period of the registration application should be submitted to the authorities if requested. Data from the accelerated storage condition and, if appropriate, from the interme

30、diate storage condition can be used to evaluate the effect of short term excursions outside the label storage conditions (such as might occur during shipping). Long term, accelerated, and, where appropriate, intermediate storage conditions for drug substances are detailed in the sections below. The

31、general case applies if the drug substance is not specifically covered by a subsequent section. Alternative storage conditions can be used if justified.2.1.7.1.
