Bracketing and matrixing are reduced designs based on different principles. Therefore, careful consideration and scientific justification should precede the use of bracketing and matrixing together in one design. 2.3 Bracketing As defined in the glossary to the parent guideline, bracketing is the design of a stabilit Bracketing and matrixing can be done in full study designs that aim to test the new drug substances for every combination of all design factors included in the technical guidelines, or in reduced study designs that focus on testing some of the drug samples or components while ignoring others FDA Guidance for Industry: Bracketing and Matrixing Fortunately, there are well-accepted procedures, namely bracketing and matrixing (B&M), to reduce the amount of stability testing required BRACKETING AND MATRIXING DESIGNS (Q1D) · To reduce the total number of samples to be tested, the ICH guidelines introduced the concept of bracketing and matrixing. · Definition: Bracketing is the design of a stability schedule such that only samples on the extremes (high level) of certain design factors (e.g., strength, container size and/or.

Bracketing Design : 3 variasi volume dengan 3 variasi kemasan. Cukup diuji pada daerah ekstrim, kalo hasil pengujian variasi kemasan ga mempengaruhi stabilitas, maka pengujian variasi volume cukup pd daerah ektrim (vol <<< dan vol >>>) Matrixing : dilakukan pada semua kombinasi namun dipilih pada titik-titik tertentu (ga di setiap waktu. Unlike Bracketing that tests the extremes of design factors at all timepoints, a matrixed design reduces the total cost of a study by testing a subset of the total of number of possible samples for all design factor combinations at specified timepoints The use of bracketing/matrixing for the validation of a manufacturing process across different products should be approached with caution because of the risk of overlooking other possible affects of the change. Use of this type of bracketing/matrixing requires a good understanding of the processes involved and the risks being assumed. For example
