For drug substances 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 condition, 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, increased testing should be conducted either by adding samples at the final time point or by including a fourth time point in the study design. Drug Substance2017-ICH指导原则稳定性 Testing Frequency •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 time points, including the initial and final time points (e.g., 0, 6, 9, 12 months), from a 12-month study is recommended.

The likely changes on storage and the rationale for the selection of attributes to be tested in the formal stability studies should be stated. •成品稳定性试验设计应以原料药的性质以及从临床处方研究和原料药稳定性研究中得到的经验为基础，应阐述贮存中可能发生的变化以及将产品可变因素选入试验方案的理由。
Drug Product 2017-ICH指导原则稳定性 Selection of Batches •Data from stability studies should be provided on at least three primary batches of the drug product. The primary batches should be of the same formulation and packaged in the same container closure system as proposed for marketing. The manufacturing process used for primary batches should simulate that to be applied to production batches and should provide product of the same quality and meeting the same specification as that intended for marketing. Two of the three batches should be at least pilot scale batches and the third one can be smaller, if justified. Where possible, batches of the drug product should be manufactured by using different batches of the drug substance.Drug Product 2017-ICH指导原则稳定性 Selection of Batches •加速和长期试验的稳定性资料至少应包括与上市产品具有相同处方、剂型和容器及闭塞物的三批样品的数据，三批中至少有两批样品应是试生产规模生产的，第三批可以少一些(如：固体口服剂型可以25000~50000 片剂或胶囊)。

A 5% change in assay from its initial value; or failure to meet the acceptance criteria for potency when using biological or immunological procedures; •2. Any degradation product’s exceeding its acceptance criterion; •3. Failure to meet the acceptance criteria for appearance, physical attributes, and functionality test (e.g., color, phase separation, resuspendibility, caking, hardness, dose delivery per actuation); however, some changes in physical attributes (e.g., softening of suppositories, melting of creams) may be expected under accelerated conditions; •and, as appropriate for the dosage form: •4. Failure to meet the acceptance criterion for pH; or •5.
