This topic provides procedures for creating and managing stability studies including when they are performed, and what essential guidelines exist for stability testing programs. The topic also provides an overview of the stability study lifecycle management, including the creation of test interval plans and the creation of a storage condition plan. You are given guidance on the creation and management of a stability study, including the assignment of its material sources, editing stability study variants and time points, and defining its storage packages.
This chapter covers the following topics:
Following are some requirements addressed in defining and managing stability testing in Quality Management.
Yes. The stability study functionality is designed to assess the stability characteristics of products, and helps you evaluate product storage conditions and expiration dating. By supplying a repository for the collection and processing of this information, OPM stability studies assists in the documentation of a written testing program. Use the Oracle attachments functionality to link written materials to the stability study.
Use the Stability Study Window as a Launch Pad for the Entire Study
The Stability Study window lets you enter preliminary information about the study including its document number, description, and storage condition plan. Display the status of the study, the master item specification used to evaluate product performance, the laboratory organization conducting the study, and the owner of the study. Display additional information, including the number of variant material sources, storage conditions investigated, and packaging configurations investigated in the study. Once the study is launched, you can monitor all the dates associated to the study. At the completion of the study, the Stability Study window lets you enter recommendations for shelf life and storage specification for the material tested. Use Oracle attachments to link written materials to the stability study.
Yes. Each of the statistical variables for the stability study can be set up to evaluate the effects of sample size, test interval, and the impact of environmental variables on each individual variant in the stability study.
Create a Test Interval Plan, Storage Condition Plan, and Variants
The Test Interval Plan window lets you simulate, evaluate, and select test intervals for the study to help you plan for statistical evaluations of study data. Use the Storage Condition Plans window to structure a set of storage conditions to apply to a study. Each storage condition includes a monitoring specification for the environmental chamber and the test interval plan. The application creates a variant for each storage condition, sample material source, and storage package combination. Edit these variants on the Variant window.
Yes. Set up the stability study for additional retained samples that are not tested as part of the study, but are retained for historical purposes.
Use Sample Disposition to Indicate Sample Retention
Use sample disposition to indicate samples to retain in storage prior to stability testing.
Yes. Test reliability is assessed through standard procedures that document test performance. These measures include test sensitivity, test specificity, and test linearity. Set up specifications for each test referencing a test method. By comparing the results of these individual tests to accepted reference tests, you can assess the correlation to these methods as a measure of test accuracy.
Trace Results Back to Test Methods
OPM Quality Management lets you trace a test result directly to the tester and test method used. The traceability of test method attributes includes the quantity of material required, the instrument used to perform the test, the number of replicates used, the identification of the test kit, the duration of the test, and the decimal precision of the result. Enter realistic test targets and acceptable ranges of test performance that meet or exceed the performance of accepted reference test methods by setting up specifications for each test performed. By incorporating control materials in each test run, monitor test performance. Use control materials to evaluate correlation to reference test method performance as an assessment of test accuracy.
Yes. Set up one or more packages or container closure systems to be investigated in the stability study.
Enter Package Configurations on the Stability Study Window
Enter the Packages field as the total number of packaging configurations you plan to use to build the study. The default is one package. Study individual package closure systems to compare and contrast product performance in various packaging configurations.
Yes. Determine the acceptable number of batches to evaluate in the study. Records of all data for expiration dating is maintained in a single referenced study for rapid retrieval and analysis.
Use the Material Source Field to Define Materials to Test
The required number of source materials is defined on the Stability Study window. Identify the item, lot, and batches that become the basis for the stability study. Source materials can exist in inventory, or can be requested from production for the study.
Yes. Set up the recommended storage condition variants in parallel to the accelerated studies. Evaluate basic stability information on the components, products, and container closure systems. Use this information to support tentative expiration dates when the full shelf life studies are not yet available. This indicative information helps you initiate long-term studies such as clinical investigations.
Use Storage Condition Plan and Variants to Deliver Both Standard and Accelerated Stability Testing
Create a robust storage condition plan that includes both the standard and accelerated environmental storage conditions for materials to test in the stability study. Variants can then be tested in all specified environments simultaneously to deliver both standard and accelerated stability study test results.
Stability studies are performed in life sciences, chemical, and food and beverage industries to determine the effects of environmental conditions on product quality. Environmental conditions can impact product shelf life, and the viability of product formulation. Stability studies provide the supporting data that companies use to establish product storage requirements and expiration dating.
Stability studies are performed at various stages of the product development process. Early stages of stability testing are typically performed on laboratory materials to determine if the material to be produced has any inherent sensitivities to storage or shipping environments. Many manufacturers perform accelerated stability testing at relatively high temperatures and humidities as a worst case scenario to determine what types of degradation products can experience after long-term storage. Materials produced in a full production run are tested under controlled temperature and humidity storage conditions that simulate environmental extremes. Results of testing on these materials provide valuable information about overall product stability, and serve as a basis for product claims on storage requirements and shelf life.
There are a number of key national and international standards, laws, regulations, and guidelines for Good Manufacturing Practice (cGMP). The U.S. Food & Drug Administration (FDA) provides compliance guidelines for drugs and medical devices. The International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) is a consortium of regulatory authorities from Europe, Japan, the United States, and experts from the pharmaceutical industry worldwide. This group discusses scientific and technical aspects of product registration. The ICH makes recommendations on the interpretation and application of technical guidelines and requirements for product registration.
Section 211.166 of the FDA guidelines requires companies who produce finished pharmaceutical products to have a written stability program. The results of this program are used in determining appropriate storage conditions and product expiration dating. This guideline specifies what to include in a stability program. The following summarizes some of the essentials presented in this guideline:
A written testing program designed to assess the stability characteristics of drug products. The results of this stability testing program used in determining appropriate drug product storage conditions and expiration dating.
The written program must be followed, and it must include:
Sample size and test intervals based on statistical criteria for each attribute examined to assure valid estimates of stability.
Testing of the drug product in the same container closure system in which the drug product is marketed.
Testing of drug products for reconstitution at the time of dispensing as directed in the labeling as well as after they are reconstituted.
Testing of an adequate number of batches of each drug product to determine an appropriate expiration date. Records of this data must be maintained.
Accelerated studies, combined with basic stability information on the components, drug products, and container closure system, is used to support tentative expiration dates provided full shelf life studies are not available and are being conducted.
Where data from accelerated studies are used to project a tentative expiration date that is beyond a date supported by actual shelf life studies. There must be stability studies conducted, including drug product testing at appropriate intervals, until the tentative expiration date is verified or the appropriate expiration date determined.
In the following program, both study protocols are run concurrently, so that expiration dating does not factor into the interpretation of results.
There are two testing procedures to run:
Within-lot stability at 25 deg C/30% RH - Batch 1, Lot X
A typical monitoring specification can be set up for temperature and humidity as follows:
The temperature range is -10 deg C to 100 deg C. The target for a monitoring specification is 25 deg C, with a minimum of 24 deg C, and a maximum of 26 deg C.
The humidity range is 0% RH to 100% RH. The target for a monitoring specification is 30% RH, with a minimum of 29% RH, and a maximum of 31% RH.
Between-lot stability at 25 deg C/30% RH - Batch 2, Lot Y, Batch 3, Lot Z. Use the same monitoring specification that was designed for within-lot stability testing.
A robust stability study can contain within-lot and between-lot investigations for various combinations of temperature and humidity. This approach provides an extensive profile of material stability at a variety of temperatures and relative humidities. The following is an example of this type of study:
Within-lot stability at specified ICH conditions for Batch 1, Lot X
25 deg C/40% RH
25 deg C/60% RH
30 deg C/35% RH
30 deg C/60% RH
40 deg C/20% RH
40 deg C/75% RH
60 deg C/20% RH
60 deg C/75% RH
Between-lot stability at specified ICH conditions for - Batch 2, Lot Y, Batch 3, Lot Z
25 deg C/40% RH
25 deg C/60% RH
30 deg C/35% RH
30 deg C/60% RH
40 deg C/20% RH
40 deg C/75% RH
60 deg C/20% RH
60 deg C/75% RH
Oracle Process Manufacturing (OPM) Quality Management stability studies let you create both simple and robust stability studies. The stability study owner remains in full control of the variants created for each time point, and monitors the progress of the study through workflow notifications. The workflow and Oracle E-Records events associated with the stability study document critical decisions to support the written study program.
Following are stages that define a typical stability study lifecycle:
Setting Up for a Stability Study
Planning a Stability Study
Performing Initial Sampling and Testing
Approving a Stability Study Plan
Launching a Stability Study
Performing Stability Study Testing
Evaluating a Stability Study
Following are steps that describe the process of setting up for a stability study:
Define test interval plans before creating a storage condition plan for a stability study. Each test interval plan represents a unique set of testing time points that list the junctures at which you plan to test samples in the stability study. The frequency or intervals between time points vary depending on the purpose of a storage condition. For example, long-term, intermediate, or accelerated storage conditions can have very different frequencies between time points.
All test interval plans that use the storage conditions of a stability study must be either a base interval plan or an overlay of the base interval plan assigned to the storage condition plan. Define interval periods as the testing frequencies required by the storage condition.
Define base test interval plan as the total set of testing time points used by each of the stability study storage conditions. If all storage conditions test the sample material at the same frequency or time intervals, then this is the only test interval plan you define.
Define an overlay test interval plan when a stability study storage condition performs time point tests with a different set of time intervals from those defined in the base test interval plan. You can enter additional time points for the overlay interval plan. You cannot delete time points on the overlay interval plan that come from the base interval plan, however, you can exclude them.
Create specifications to define the environmental monitoring criteria for the storage conditions. These are called monitoring specifications. A monitoring or nonitem specification must be created to include tests that support each required storage condition detail such as ambient temperature, relative humidity, and atmospheric pressure. Assign tests to the monitoring specifications. Create a specification validity rule to specify the resource or physical location to monitor.
Create the required set of storage conditions. These conditions include a unique combination of temperature and relative humidity measurements that differentiate testing conditions for a stability study. The storage conditions created require the environmental monitoring of a defined equipment resource such as a refrigerator or a subinventory locator in a particular storage organization. The planned and actual storage condition parameters must be monitored for each storage condition combination. For example, 30 deg C/60% RH requires the monitoring of both the 30 deg C refrigeration and 60% RH ambient moisture content.
Define the two components of a storage condition plan:
A monitoring specification to define the details of the storage condition for each one of the variants in the stability study
A test interval plan to define testing time points by indicating the test intervals for each variant in the stability study
Decide on the package to use for the container closure system for the product to test in a particular organization. Create a storage package configuration.
Create base and overlay item specifications that contain the tests you use in stability testing. These are usually based on the product release specifications which are a combination of physical, chemical, biological, and microbiological tests and acceptance criteria that determine the suitability of a product at the time of its release. The base specification serves as the default item specification when you create the stability study. You can associate the overlay specifications to time points when the stability testing requirements vary from the base specification.
Set up document numbering using the Samples tab in the Process Quality Parameters window for the organization where you plan to perform the sampling.
Set up document numbering using the Stability Studies tab in the Process Quality Parameters window for the stability study organization.
Following are steps that describe the planning of a stability study:
Create a stability study with the following information:
Item as the process quality-enabled item to test in the stability study
Master item specification to use in evaluating item performance in the stability study
Study name to record a unique identifier for the stability study entity
Protocol to enter as part of the study description to capture the purpose of the stability study
Study start, notification lead time, testing grace period, and completion dates to define the beginning and end dates for study
Study approval process with status control. Stability study status controls sample pull and testing notifications, and specifies how all associated samples are consumed, allocated, or used for testing in the study
Refer to the "Creating and Managing a Stability Study" topic for more information on creating a stability study.
Assign the storage condition plan to the stability study. This plan consists of the monitoring specification that provides the details of the storage condition for each one of the variants in the stability study, and a test interval plan that defines the testing time points.
Identify the item, lot, and batches that serve as the basis for the stability study. The source material can already exist in a material source inventory organization as lots or it can be selected, or requested as batch. Batches can be initial production batches for a new formulation, or a portion of routine production batches pulled for stability testing. This information includes the item, lot, batch number, date of manufacture or product yield date, sample quantity and UOM, recipe, recipe version used, and sample quantity.
Plan all variant storage conditions for each time point sample or sample group. Variants are defined by the unique combination of the stability study storage condition in a storage organization, the test interval plan, the package, and material source. Specify the default item specification, number of stability samples per time point, and the number of retained samples for the variant. You can configure the default item specification for the variant to select an overlay specification for a time point.
Following are steps that describe initial sampling and testing in a stability study:
When acquiring the initial material to use as a basis for a stability study, the item lots must be allocated or reserved as inventory for use only in the stability study. Material must be physically stored in a subinventory, locator, and container, or moved directly from the manufacturing floor to a staging area where initial testing is performed. Samples used in stability studies reflect inventory consumption and sample movement into storage subinventory locators to manage environmental variants. An initial stability sample can be retained, or moved into a storage subinventory and locator.
Define the test criteria to perform for the initial stability sample. If an approved, prerelease, laboratory specification exists for the material, then use that specification. If an approved production specification exists for the product, then use it for the initial sample testing. The selected sample specification must be entered as the master item specification defined in the stability study. The outcome of these tests determines whether an item lot or batch is used for continuing the stability study. Initial sampling and testing must indicate acceptable source material before the stability study is launched.
Associate the initial samples with a material source by selecting the appropriate sample group. Only initial sample groups with a disposition of Accept or Accept with Variance are listed. Make this association prior to launching the stability study.
Following are steps required to approve a stability study plan:
Use the Change Status action on the Stability Study window to request stability study approval. This initiates the Stability Study Change Status workflow which notifies the study owner of the request for status change in the stability study. The process of changing the status from NEW to a status of Stability Study Plan Approved is managed by the workflow. Oracle E-Records works with the workflow to enforce generation of an electronic record and capture of electronic signatures for each status change.
If material source lots are identified, then stability sample groups and samples are created by the application for the planned variants and time points. These samples are based on the:
Number of samples per time point
Number of retained samples for a variant
Sample quantity and UOM defined for a variant
These system-generated item samples are automatically associated to a stability study as identified by the sample source fields. You cannot create stability samples manually through the Samples window.
If the material source is requested as a batch, then the appropriate workflow initiates for batch and sample creation. Prior to launching the stability study, specify a lot on the Material Sources window.
The application generates the schedule dates for all the testing time points based on the stability study scheduled start date. A sample group is generated for each testing time point to permit the assignment of a final disposition to each point.
Finalize the availability and acceptability of the lots for every material source listed on the Material Sources window. Specify the lot for any batch requested to produce as a material source. Enter material source organization as the inventory organization where the sample material is produced. Prior to launching the stability study, each material source must have an acceptable initial sample group. If you cannot finalize all material sources at this time, then finalize them before you launch the stability study.
The Testing Time Point Label Generation report produces a pdf file. For each testing time point, the report produces the name of the stability study, variant, testing time point, sample number, time point scheduled date, and sample quantity.
You can generate this report for:
All testing time points for variants of a stability study
All testing time points for an individual variant
A specific time point for an individual variant
Regenerate the report for a specific variant time point if you add a time point to a variant during the study.
If packaging is specified for the variant, then put the sample material for each variant time point in individual packages. If labels were generated, then apply them to the sample storage package. Place the materials in the defined variant storage conditions in the specified storage organization. Update the storage date of stability samples for each variant.
Determine that there are sufficient sample materials to conduct the stability study. The total sample quantity must be validated to determine if there is sufficient quantity of material for each variant time point sample. This validation ensures there is sufficient material to complete the required analysis. Positive material identification is essential to a fully traceable stability study.
Following are steps required to launch a stability study:
If material sources are not finalized, then repeat steps 2 through 6 in the "Approving the Stability Study Plan" topic.
Once all source materials have an initial sample group with an acceptable disposition, the stability study owner can launch the approved stability study.
Following are steps required to perform stability study testing:
Change the status of the stability study to In Progress.
You receive notification to pull samples for stability study testing. The Stability Study Testing Notification master workflow governs this process.
Identify samples that require testing on the scheduled time point dates, and use the specification assigned to the time point to test the samples. If necessary, assign a retained sample for a variant to a point for time point testing.
Use the monitoring specification to evaluate the environmental conditions used in the study. The Sample Group Rejection workflow notifies you when either a monitoring sample group, or a stability study time point sample group is rejected.
Enter results for time point testing and evaluate them against the specification assigned to the time point. The Sample Group Rejection workflow notifies you when either a monitoring sample group, or a stability study time point sample group is rejected.
Following are steps that describe the evaluation of a stability study:
The Stability Study disposition is complete when the scheduled testing time points have a final disposition required to perform the stability study analysis. The stability study owner determines testing is complete when all scheduled testing time points variants have a final disposition, or when a sufficient number of testing time points have a rejected disposition for a specific variant, in which case it would be unnecessary to continue testing.
The stability study owner reviews all test result data.
The stability study owner determines whether additional testing is required for any of the time points in the study.
The stability study owner concludes the stability study by:
Changing the status of the stability study to Completed
Entering a study end date
Entering the recommended shelf life derived from the results of tests performed on variants in the study that met the item specification
Entering the recommended storage conditions derived from the monitoring specification used for the variants in the study that met the item specification
The stability study owner communicates the results of the stability study to appropriate individuals within the supply chain.
When the OPM Quality Stability Study Change Status workflow is activated the stability study requires a series of approvals that result in reassigning status through a predefined approval process.
Stability study statuses are preseeded. Refer to the "OPM Quality Stability Study Change Status Workflow" topic in "Appendix C" for additional information.
Set up the workflow. Contact a system administrator if you are not sure this is set up.
Enable the workflow. Enable the Stability Study Change Status workflow by setting it up in the System Administration application. The workflow is activated initially by changing the status of a stability study from New to Request Approval of Stability Study Plan.
Upon creation of a stability study, the default Status is New.
Choose Stability Study Plan Approved from the Actions menu to submit the stability study plan for approval. The status displays as Request Approval of Stability Study Plan.
If the stability study plan is approved, then the status changes to Stability Study Plan Approved. Proceed to step 2.
If the stability study plan is rejected, then the status changes to Revise Stability Study Plan. Repeat this step.
Choose Launch Approved from the Actions menu to submit the stability study for launch. The status displays as Request Approval to Launch.
If the stability study launch is approved, then the status changes to Launch Approved. Proceed to step 3.
If the stability study launch is rejected, then the status changes to Revise Launch. Repeat this step.
Choose In Progress from the Actions menu to perform stability study testing, .
Choose Completed from the Actions menu to complete the stability study, .
Choose Canceled from the Actions menu to cancel the stability study at Stability Study Plan Approved, Launch Approved, or In Progress. The status displays:
Request Approval to Cancel from Approved Plan if the stability study plan is approved, but not yet launched.
Request Approval to Cancel From Approved Launch if the stability study has an approved launch, but is not yet in progress.
Request Approval to Cancel From In Progress if the stability study is in progress.
The following depicts the previously described workflow:
The Test Interval Plan window lets you simulate a set of test interval periods to use in a stability study. The initial test interval plan saved becomes a candidate base test interval plan. Once you save a base test interval plan, you can reuse it to create an overlay test interval plan. The overlay can exclude time periods, or add time periods to the base plan.
MONTH_12 is a test interval plan that includes 12 periods spaced at one month each as follows:
MONTH-1, MONTH-2, MONTH-3, MONTH-4, MONTH-5, MONTH-6, MONTH-7, MONTH-8, MONTH-9, MONTH-10, MONTH-11, MONTH-12
When you recall MONTH_12, make it the base plan for MONTH_13, an overlay test interval plan that adds an additional month to the one year testing cycle. For example, MONTH_13 includes 13 periods spaced at one month, with the last interval being MONTH-13.
With this approach, you can create many variations of test interval plans by entering a base test interval plan and modifying the overlay test interval plan to meet your specific requirements.
For example, 2_YEAR is a test interval plan with a two year duration as follows:
1 WEEK
2 WEEKS
3 WEEKS
1 MONTH
2 MONTHS
3 MONTHS
6 MONTHS
12 MONTHS
18 MONTHS
2 YEARS
Use the Generate Test Intervals dialog box to enter a series of periods by defining a total duration and a frequency to repeat each period. The interval periods are resorted in ascending order by the simulated date when you save your work. Refer to the "Generating a Series of Testing Periods" topic for more information.

The Variant window lets you edit stability study variants. This window displays all variants the application creates when the stability study is created. The total number of rows displayed on this window depends on the number of unique combinations of:
A specific batch.
A specific storage condition in a storage organization such a combination of temperature and humidity. For example, 30 deg C and 60% RH.
A specific storage package. You can set up a stability study for several storage packages, however at least one package is required.
Delete or add variants until the stability study plan is approved. Resources or locators identified for variant storage conditions can also be replaced if they do not meet environmental monitoring requirements.
Each row on the Variant window represents an individual material source, storage condition, and storage package combination. Based on the variant count for a new stability study, the application creates a variant for each of these combinations. It is assumed that stability study sample material from each source is stored in each storage condition and storage package combination for the specified duration. Sample material from a batch is stored at one or several storage conditions in a process-enabled inventory storage organization, depending on the scope of the stability study.
Plan or edit variants once material sources are defined. However, changes to the number of acceptable material sources can affect the number of planned variants before a stability study plan is approved. Add, edit, or delete variants until the stability study plan is approved. Once the stability study is in progress, you can only edit the variant end date, or replace the resource or physical location for a storage condition.
