1.0 Purpose 
 
 The purpose of this procedure is to describe the processes used for validation and routine
 
 execution of methods used for screening of surface allergens, cleaning agent residues, and
 product residues following cleaning of production equipment.

 This procedure applies to all cleaning verification and validation activity associated with
 
 manufacturing processes. This procedure outlines the overall process to conduct necessary
 
 activities under protocol. This procedure includes the evaluation of test cleaning verification test
 methods for suitability of the test for the intended purpose as well as the application of
 
 verification methods to validate a cleaning process. 
 
 3.0 Responsibility 
 
 3.1 It is the responsibility of QC Management to implement and maintain this procedure.
 
 3.2 It is the responsibility of QC Management and R&D Management to ensure that this
 procedure is followed. 
 
 3.3. It is the responsibility of QC Chemists and R&D personnel to execute validation and
 verification activities.

 6.0 Procedure 
 
 6.1 Process Overview 
 
 6.1.1 Cleaning processes are divided into two categories. 
 
 6.1.1.1 Manual cleaning processes are typically not validated. Manual cleaning
 processes are typically verified after every clean. It is acceptable to
 
 validate a manual cleaning process; however, verification is preferred
 unless the manual cleaning process is very consistent. 
 
 6.1.1.2 Automated cleaning processes must be validated unless verified after
 every clean. Automated cleaning processes include CIP systems.
 
 6.1.2 Test methods used for verification and/or validation of cleaning processes must
 
 be suitable for the intended purpose. Test methods used for this purpose must
 detect analytes of interest at levels associated with acceptable residual limits.
 
 Validation and Verification of each specific test method is covered by SOP D-
 103 Analytical Method Validation and Verification. 
 
 6.1.3 Cleaning Validation is defined and documented through protocols and reports.
 Requirements for protocols and reports are covered by SOP C-105 Protocol and
 
 Report Documentation Requirements. The following parameters are typically
 
 used in a cleaning validation protocol. Protocols may use alternate approaches as
 justified in the protocol. 
 
 6.1.3.1 The cleaning process must be well defined and documented. If the
 cleaning process is altered, the cleaning validation should be repeated.

 Verification and Validation of Cleaning Processes 
 Adding detail to the cleaning method does not necessarily indicate
 
 alteration. 
 
 6.1.3.2 Limits for analytes of interest are defined. Limits should be based on
 
 safety and risk assessment which should be discussed in the protocol.
 
 6.1.3.3 Sample collection methods are defined. 
 
 6.1.3.4 Testing methods are defined. Testing methods should be suitable for the
 
 intended purpose as discussed above. 
 
 6.1.3.5 Execution of cleaning with protocol-defined verification testing is
 
 repeated at least three (3) times successfully without intermittent
 failures. 
 
 Cleaning validation may include matrix approaches to include best-case / worst-
 case scenarios. Best-case / worst-case scenarios may be determined by solubility,
 
 identified risks, identified detectability, etc. Matrix approaches are defined and
 
 justified in protocols / reports applicable to the cleaning process.
 
 6.2 Verification of Cleaning 
 
 6.2.1 Verification of cleaning is the process of inspection, sampling, and/or testing to
 determine that equipment is satisfactorily clean. Cleaning verification is used
 
 after every clean for cleaning processes which are not validated. Cleaning
 verification is used during cleaning validation protocols to determine success or
 
 failure of that validation protocol. Various cleaning verification methods are
 available and the choice of which methods are used is dependent upon the nature
 
 of the analyte of concern. 
 
 6.2.2 Verification typically includes visual inspection, ATP swabs, and if known-
 allergens are present in the previous product, verification includes allergen swabs.
 
 6.2.3 For high potent compounds (i.e. Active Pharmaceutical Ingredients - API)

 verification may include the use of analytical methods specific to a particular API
 
 or other compound of interest. 
 
 6.3 Swab and Flush Sample Collection 
 
 6.3.1 Some test kits contain swabs as part of the test kit. Where specific instructions
 
 are available to a test kit, those instructions supersede the instructions provide
 here. 
 
 6.3.2 Select a swab suitable for the intended purpose. 
 
 6.3.3 For samples generated by swab, a 10cm X 10cm surface area will be swabbed in
 
 one direction using one side of the swab. The swab will then be turned over and
 the surface swabbed in a 90° direction from the first. When obtaining a sample
 
 from a hard to clean surface or convoluted surface approximate 100cm? as your
 sample area. Other sized surface areas can be used with proper scientific
 
 justification.

 6.3.4 For areas unreachable by swab, flushing with a fixed quantity of rinse agent
 (typically water) can be performed. The rinse volume should be a quantity that
 
 allows sufficient sensitivity for the surface area tested. 
 
 6.3.5 A suitable number of test samples will be taken to effectively demonstrate that

 the piece of equipment is residue free. 
 
 6.3.5.1 The sampling should be from surfaces that come into contact with the
 finished product material but other surfaces are acceptable to ensure
 
 complete cleaning. 
 
 6.3.5.2 If multiple surface types exist at least one representative sample from
 
 each surface type must be taken. 
 
 6.3.5.3 If corners, edges, channels or other hard to clean areas come in contact
 with finished product material at least one hard to clean area must be
 
 included in the sampling process.
