这么说吧,既然指南已经给你间隔时间,为什么不遵守呢,没那个必要,因为全世界所有药企基本都这么干。但是也不是说必须这么干。你设置1/2/4/6/8/12...也是可以的。guideline没有法律强制性。
Testing Frequency
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.
For long term studies, frequency of testing should be sufficient to establish the stability profile of the drug substance. 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. |
