PHARMACEUTICAL QUALITY ASSURANCE INTERVIEW QUESTIONS

PHARMACEUTICAL QUALITY ASSURANCE INTERVIEW QUESTIONS

1Q. Why water for pharmaceutical use is always kept in close loop in continuous circulation?
A. Water is a best medium for many microorganisms, microorganism can be a highly pathogenic which causes serious diseases(many diseases are water born), these pathogens infect after consumption of contaminated water, microorganisms tend to settle on a surface if water is allowed to stand in a stagnant position for few hours, these settled microorganism form a film over the surface of vessel and piping, such film formed by microorganisms is also called as biofilm, biofilms are very difficult of remove, once a biofilm is formed at a particular point then that point may form a biofilm again even after cleaning very easily as seed from this point is may not completely get removed effectively. Biofilms then can become a source of microbial contaminations; therefore purified water after collection in a distribution system is always kept in a closed loop in a continuous circulation. A continuous circulation is also not enough at some points, therefore it is aided with high temperature range from 65 °C to 80°C, a minimum temperature of 65 °C is considered a selfsanitizing, but better assurance is obtained with a temperature of 80°C . Purified water collected should be stored in a stainless still vessel which must facilitate distribution to the point of use in a closed loop of continuous circulation, tank should be made of corrosion free material of construction, and must facilitate sanitization and easy cleaning.

2 Q. Water for pharmaceutical use shall be free cations,anions and other impurities why ?
A.Water for pharmaceutical must be free from inorganic as well as organic impurities, minerals, and heavy metals. Some impurities like calcium, magnesium, ferrous are responsible for degradation of drug molecule, many cations like ferrous and calcium magnesium act as catalysts in degradation reaction of drug molecule, anions like chloride are highly active they participate in nucliophylic substitution reactions, where in they break a double bond between -C=C- in to a single bond as CL –CH-CH2- , which a reason why we observe that color dies tend to fed in presence of chlorine as most of the dies used are diazo compounds which has plenty of places for nucliophylic substitution reactions, which is also a reason why stability of drug is drastically affected in presence of cations and anions from mineral origin present in water.

3. Q. Water for pharmaceutical use shall be free heavy metals why ?
A. Heavy metals like lead and arsenic are highly cumulative neurotoxic metals, heavy metals are not eliminated out of our body easily like other drugs and molecules but heavy metals bind with proteins and tend to get accumulated in fatty tissues, nerve tissue is most likely to get damaged by heavy metals, heavy metal causes nervous tissue damage there for water must be free from heavy metals.

4. Q. Brazil falls under which climatic zone ?
A. Zone IVB (30 degree celsius and 75% relative humidity)



5. Q. Change in the size or shape of the original container requires any stability study?
A. Change in the size or shape of the original container may not necessitate the initiation of new stability study.

6. Q. Forced degradation(stress testing) and accelerated stability testing are same?
A. Forced degradation and stress testing are not same. Stress testing is likely to be carried out on a single batch of the drug substance. The testing should include the effect of temperatures (in 10°C increments (e.g., 50°C, 60°C) above that for accelerated testing), humidity (e.g., 75 percent relative humidity or greater) where appropriate, oxidation, and photolysis on the drug substance. The testing should also evaluate the susceptibility of the drug substance to hydrolysis across a wide range of pH values when in solution or suspension. Photo stability testing should be an integral part of stress testing.

7. Q. According to WHO guidelines what is the storage condition of climatic zone IVa and zone IVb?
A. Zone IV a: 30°C and 65% RH (hot and humid countries) Zone IV b: 30°C and 75% RH (hot and very humid countries

8. Q. Countries comes under climatic zone IVb?
A.Brazil,Cuba,China,Brunei,Cambodia,Indonesia,Malaysia,Myanmar,Philippines,Singapore,Thailand

9. Q. What is the purpose of stress testing in stability studies?
A. Stress testing of the drug substance can help identify the likely degradation products, which can in turn help establish the degradation pathways and the intrinsic stability of the molecule and validate the stability indicating power of the analytical procedures used. The nature of the stress testing will depend on the individual drug substance and the type of drug product involved.

10. Q. What is the formula for calculating number of air changes in an area?
A. Number of air changes/hour in an area is = Total Room Airflow In CFM x 60/Total Volume of room in cubic feet
For calculating Total Room Airflow in CFM, first calculate air flow of individual filter. Formula is given below.
Air flow (in cfm) = Avg.air velocity in feet/Minute x Effective area of filter
Then find Total air flow. Formula is Total Air flow = Sum of air flow of individual filter.
Air flow Velocity can be measured with the help of Anemometer.

11. Q. What is dead leg?
A. A dead leg is defined as an area in a piping system where liquid can become stagnant and not be exchanged during flushing.


12. Q. What is the recommended bio burden limits of purified water & WFI?

50 Most Common Interview Questions

50 Most Common Interview Questions

50 Most Common Interview Questions 


1. Tell me about yourself: The most often asked question in interviews. You need to have a short statement prepared in your mind. Be careful that it does not sound rehearsed. Limit it to work-related items unless instructed otherwise. Talk about things you have done and jobs you have held that relate to the position you are interviewing for. Start with the item farthest back and work up to the present.


2. Why did you leave your last job? Stay positive regardless of the circumstances. Never refer to a major problem with management and never speak ill of supervisors, co-workers or the organization. If you do, you will be the one looking bad. Keep smiling and talk about leaving for a positive reason such as an opportunity, a chance to do something special or other forward-looking reasons.


3. What experience do you have in this field? Speak about specifics that relate to the position you are applying for. If you do not have specific experience, get as close as you can.


4. Do you consider yourself successful? You should always answer yes and briefly explain why. A good explanation is that you have set goals, and you have met some and are on track to achieve the others.


5. What do co-workers say about you? Be prepared with a quote or two from co-workers. Either a specific statement or a paraphrase will work. Jill Clark, a co-worker at Smith Company, always said I was the hardest workers she had ever known. It is as powerful as Jill having said it at the interview herself.



6. What do you know about this organization? This question is one reason to do some research on the organization before the interview. Find out where they have been and where they are going. What are the current issues and who are the major players?


7. What have you done to improve your knowledge in the last year? Try to include improvement activities that relate to the job. A wide variety of activities can be mentioned as positive selfimprovement. Have some good ones handy to mention.


8. Are you applying for other jobs? Be honest but do not spend a lot of time in this area. Keep the focus on this job and what you can do for this organization. Anything else is a distraction.



9. Why do you want to work for this organization? This may take some thought and certainly, should be based on the research you have done on the organization. Sincerity is extremely important here and will easily be sensed. Relate it to your long-term career goals.


 10. Do you know anyone who works for us? Be aware of the policy on relatives working for the organization. This can affect your answer even though they asked about friends not relatives. Be careful to mention a friend only if they are well thought of.



11. What kind of salary do you need? A loaded question. A nasty little game that you will probably lose if you answer first. So, do not answer it. Instead, say something like, That’s a tough question. Can you tell me the range for this position? In most cases, the interviewer, taken off guard, will tell you. If not, say that it can depend on the details of the job. Then give a wide range.



12. Are you a team player? You are, of course, a team player. Be sure to have examples ready. Specifics that show you often perform for the good of the team rather than for yourself are good evidence of your team attitude. Do not brag, just say it in a matter-of-fact tone. This is a key point.


13. How long would you expect to work for us if hired? Specifics here are not good. Something like this should work: I’d like it to be a long time. Or As long as we both feel I’m doing a good job.


14. Have you ever had to fire anyone? How did you feel about that? This is serious. Do not make light of it or in any way seem like you like to fire people. At the same time, you will do it when it is the right thing to do. When it comes to the organization versus the individual who has created a harmful situation, you will protect the organization. Remember firing is not the same as layoff or reduction in force.



15. What is your philosophy towards work? The interviewer is not looking for a long or flowery dissertation here. Do you have strong feelings that the job gets done? Yes. That’s the type of answer that works best here. Short and positive, showing a benefit to the organization.



16. If you had enough money to retire right now, would you? Answer yes if you would. But since you need to work, this is the type of work you prefer. Do not say yes if you do not mean it.



17. Have you ever been asked to leave a position? If you have not, say no. If you have, be honest, brief and avoid saying negative things about the people or organization involved.



18. Explain how you would be an asset to this organization You should be anxious for this question. It gives you a chance to highlight your best points as they relate to the position being discussed. Give a little advance thought to this relationship.


19. Why should we hire you? Point out how your assets meet what the organization needs. Do not mention any other candidates to make a comparison.


20. Tell me about a suggestion you have made Have a good one ready. Be sure and use a suggestion that was accepted and was then considered successful. One related to the type of work applied for is a real plus.


 21. What irritates you about co-workers? This is a trap question. Think real hard but fail to come up with anything that irritates you. A short statement that you seem to get along with folks is great.


22. What is your greatest strength? Numerous answers are good, just stay positive. A few good examples:Your ability to prioritize, Your problem-solving skills, Your ability to work under pressure, Your ability to focus on projects, Your professional expertise, Your leadership skills, Your positive attitude


23. Tell me about your dream job. Stay away from a specific job. You cannot win. If you say the job you are contending for is it, you strain credibility. If you say another job is it, you plant the suspicion that you will be dissatisfied with this position if hired. The best is to stay genetic and say something like: A job where I love the work, like the people, can contribute and can’t wait to get to work.


24. Why do you think you would do well at this job? Give several reasons and include skills, experience and interest.



25. What are you looking for in a job? See answer # 23



26. What kind of person would you refuse to work with? Do not be trivial. It would take disloyalty to the organization, violence or lawbreaking to get you to object. Minor objections will label you as a whiner.


27. What is more important to you: the money or the work? Money is always important, but the work is the most important. There is no better answer.


28. What would your previous supervisor say your strongest point is? There are numerous good possibilities: Loyalty, Energy, Positive attitude, Leadership, Team player, Expertise, Initiative, Patience, Hard work, Creativity, Problem solver


29. Tell me about a problem you had with a supervisor Biggest trap of all. This is a test to see if you will speak ill of your boss. If you fall for it and tell about a problem with a former boss, you may well below the interview right there. Stay positive and develop a poor memory about any trouble with a supervisor.



30. What has disappointed you about a job? Don’t get trivial or negative. Safe areas are few but can include: Not enough of a challenge. You were laid off in a reduction Company did not win a contract, which would have given you more responsibility.


31. Tell me about your ability to work under pressure. You may say that you thrive under certain types of pressure. Give an example that relates to the type of position applied for.



 32. Do your skills match this job or another job more closely? Probably this one. Do not give fuel to the suspicion that you may want another job more than this one.


33. What motivates you to do your best on the job? This is a personal trait that only you can say, but good examples are: Challenge, Achievement, Recognition


34. Are you willing to work overtime? Nights? Weekends? This is up to you. Be totally honest.


35. How would you know you were successful on this job? Several ways are good measures: You set high standards for yourself and meet them. Your outcomes are a success.Your boss tell you that you are successful


36. Would you be willing to relocate if required? You should be clear on this with your family prior to the interview if you think there is a chance it may come up. Do not say yes just to get the job if the real answer is no. This can create a lot of problems later on in your career. Be honest at this point and save yourself future grief.



37. Are you willing to put the interests of the organization ahead of your own? This is a straight loyalty and dedication question. Do not worry about the deep ethical and philosophical implications. Just say yes.


38. Describe your management style. Try to avoid labels. Some of the more common labels, like progressive, salesman or consensus, can have several meanings or descriptions depending on which management expert you listen to. The situational style is safe, because it says you will manage according to the situation, instead of one size fits all.



39. What have you learned from mistakes on the job? Here you have to come up with something or you strain credibility. Make it small, well intentioned mistake with a positive lesson learned. An example would be working too far ahead of colleagues on a project and thus throwing coordination off.



40. Do you have any blind spots? Trick question. If you know about blind spots, they are no longer blind spots. Do not reveal any personal areas of concern here. Let them do their own discovery on your bad points. Do not hand it to them.


41. If you were hiring a person for this job, what would you look for? Be careful to mention traits that are needed and that you have.


42. Do you think you are overqualified for this position? Regardless of your qualifications, state that you are very well qualified for the position.


43. How do you propose to compensate for your lack of experience? First, if you have experience that the interviewer does not know about, bring that up: Then, point out (if true) that you are a hard working quick learner.


 44. What qualities do you look for in a boss? Be generic and positive. Safe qualities are knowledgeable, a sense of humor, fair, loyal to subordinates and holder of high standards. All bosses think they have these traits.



45. Tell me about a time when you helped resolve a dispute between others. Pick a specific incident. Concentrate on your problem solving technique and not the dispute you settled.


46. What position do you prefer on a team working on a project? Be honest. If you are comfortable in different roles, point that out.


47. Describe your work ethic. Emphasize benefits to the organization. Things like, determination to get the job done and work hard but enjoy your work are good.



48. What has been your biggest professional disappointment? Be sure that you refer to something that was beyond your control. Show acceptance and no negative feelings.



49. Tell me about the most fun you have had on the job. Talk about having fun by accomplishing something for the organization.



50. Do you have any questions for me? Always have some questions prepared. Questions prepared where you will be an asset to the organization are good. How soon will I be able to be productive? and What type of projects will I be able to assist on? Are examples.

This draft guidance, when finalized, will represent the current thinking of the Food and Drug 5 Administration (FDA or Agency) on this topic. It does not establish any rights for any person and is not 6 binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the 7 applicable statutes and regulations. To discuss an alternative approach, contact the FDA staff responsible 8 for this guidance as listed on the title page. 9

I. INTRODUCTION 14
15
The purpose of this guidance is to clarify the role of data integrity in current good manufacturing 16 practice (CGMP) for drugs, as required in 21 CFR parts 210, 211, and 212. Part 210 covers 17 Current Good Manufacturing Practice in Manufacturing, Processing, Packing, or Holding of 18 Drugs; General; part 211 covers Current Good Manufacturing Practice for Finished 19 Pharmaceuticals; and part 212 covers Current Good Manufacturing Practice for Positron 20 Emission Tomography Drugs. This guidance provides the Agency’s current thinking on the 21 creation and handling of data in accordance with CGMP requirements. 22
23
FDA expects that data be reliable and accurate (see the “Background” section). CGMP 24 regulations and guidance allow for flexible and risk-based strategies to prevent and detect data 25 integrity issues. Firms should implement meaningful and effective strategies to manage their data 26 integrity risks based upon their process understanding and knowledge management of 27 technologies and business models. 28
29
In general, FDA’s guidance documents do not establish legally enforceable responsibilities. 30 Instead, guidances describe the Agency’s current thinking on a topic and should be viewed only 31 as recommendations, unless specific regulatory or statutory requirements are cited. The use of 32 the word should in Agency guidances means that something is suggested or recommended, but 33 not required. 34
35
II. BACKGROUND 36
37
In recent years, FDA has increasingly observed CGMP violations involving data integrity during 38 CGMP inspections. This is troubling because ensuring data integrity is an important component 39 of industry’s responsibility to ensure the safety, efficacy, and quality of drugs, and of FDA’s 40 ability to protect the public health. These data integrity-related CGMP violations have led to 41

numerous regulatory actions, including warning letters, import alerts, and consent decrees. The 42 underlying premise in §§ 210.1 and 212.2 is that CGMP sets forth minimum requirements to 43 assure that drugs meet the standards of the Federal Food, Drug, and Cosmetic Act (FD&C Act) 44 regarding safety, identity, strength, quality, and purity.2 Requirements with respect to data 45 integrity in parts 211 and 212 include, among other things: 46
47
• § 211.68 (requiring that “backup data are exact and complete,” and “secure from 48 alteration, inadvertent erasures, or loss”); 49
• § 212.110(b) (requiring that data be “stored to prevent deterioration or loss”); 50
• §§ 211.100 and 211.160 (requiring that certain activities be “documented at the time 51 of performance” and that laboratory controls be “scientifically sound”); 52
• § 211.180 (requiring that records be retained as “original records,” “true copies,” or 53 other “accurate reproductions of the original records”); and 54
• §§ 211.188, 211.194, and 212.60(g) (requiring “complete information,” “complete 55 data derived from all tests,” “complete record of all data,” and “complete records of 56 all tests performed”). 57
58
Electronic signature and record-keeping requirements are laid out in 21 CFR part 11 and apply to 59 certain records subject to records requirements set forth in Agency regulations, including parts 60 210, 211, and 212. For more information, see guidance for industry Part 11, Electronic Records; 61 Electronic Signatures — Scope and Application.3 The guidance outlines FDA’s current thinking 62 regarding the narrow scope and application of part 11 pending FDA’s reexamination of part 11 63 as it applies to all FDA-regulated products. 64
65
III. QUESTIONS AND ANSWERS 66
67
1. Please clarify the following terms as they relate to CGMP records: 68
69
a. What is “data integrity”? 70
71
For the purposes of this guidance, data integrity refers to the completeness, 72 consistency, and accuracy of data. Complete, consistent, and accurate data should 73 be attributable, legible, contemporaneously recorded, original or a true copy, and 74 accurate (ALCOA).4 75
2 FDA’s authority for CGMP comes from FD&C Act section 501(a)(2)(B), which states that a drug shall be deemed adulterated if “the methods used in, or the facilities or controls used for, its manufacture, processing, packing, or holding do not conform to or are not operated or administered in conformity with current good manufacturing practice to assure that such drug meets the requirement of the act as to safety and has the identity and strength, and meets the quality and purity characteristics, which it purports or is represented to possess.”
3 CDER updates guidances periodically. To make sure you have the most recent version of a guidance, check the FDA Drugs guidance Web page at www.fda.gov/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/default.htm.
4 For attributable, see §§ 211.101(d), 211.122, 211.186, 211.188(b)(11), and 212.50(c)(10); for legible see §§ 211.180(e) and 212.110(b); for contemporaneously recorded (at the time of performance) see §§ 211.100(b) and 211.160(a); for original or a true copy see §§ 211.180 and 211.194(a); and for accurate see §§ 211.22(a), 211.68, 211.188, and 212.60(g).

b. What is “metadata”? 76
77
Metadata is the contextual information required to understand data. A data value 78 is by itself meaningless without additional information about the data. Metadata is 79 often described as data about data. Metadata is structured information that 80 describes, explains, or otherwise makes it easier to retrieve, use, or manage data. 81 For example, the number “23” is meaningless without metadata, such as an 82 indication of the unit “mg.” Among other things, metadata for a particular piece 83 of data could include a date/time stamp for when the data were acquired, a user ID 84 of the person who conducted the test or analysis that generated the data, the 85 instrument ID used to acquire the data, audit trails, etc. 86
87
Data should be maintained throughout the record’s retention period with all 88 associated metadata required to reconstruct the CGMP activity (e.g., §§ 211.188 89 and 211.194). The relationships between data and their metadata should be 90 preserved in a secure and traceable manner. 91
92
c. What is an “audit trail”? 93
94
For purposes of this guidance, audit trail means a secure, computer-generated, 95 time-stamped electronic record that allows for reconstruction of the course of 96 events relating to the creation, modification, or deletion of an electronic record. 97 An audit trail is a chronology of the “who, what, when, and why” of a record. For 98 example, the audit trail for a high performance liquid chromatography (HPLC) 99 run could include the user name, date/time of the run, the integration parameters 100 used, and details of a reprocessing, if any, including change justification for the 101 reprocessing. 102
103
Electronic audit trails include those that track creation, modification, or deletion 104 of data (such as processing parameters and results) and those that track actions at 105 the record or system level (such as attempts to access the system or rename or 106 delete a file). 107
108
CGMP-compliant record-keeping practices prevent data from being lost or 109 obscured (see §§ 211.160(a), 211.194, and 212.110(b)). Electronic record-keeping 110 systems, which include audit trails, can fulfill these CGMP requirements. 111
112
d. How does FDA use the terms “static” and “dynamic” as they relate to record 113 formats? 114
115
For the purposes of this guidance, static is used to indicate a fixed-data document 116 such as a paper record or an electronic image, and dynamic means that the record 117 format allows interaction between the user and the record content. For example, a 118 dynamic chromatographic record may allow the user to change the baseline and 119 reprocess chromatographic data so that the resulting peaks may appear smaller or 120

Draft — Not for Implementation
4
larger. It also may allow the user to modify formulas or entries in a spreadsheet 121 used to compute test results or other information such as calculated yield. 122
123
e. How does FDA use the term “backup” in § 211.68(b)? 124
125
FDA uses the term backup in § 211.68(b) to refer to a true copy of the original 126 data that is maintained securely throughout the records retention period (for 127 example, § 211.180). The backup file should contain the data (which includes 128 associated metadata) and should be in the original format or in a format 129 compatible with the original format. 130
131
This should not be confused with backup copies that may be created during 132 normal computer use and temporarily maintained for disaster recovery (e.g., in 133 case of a computer crash or other interruption). Such temporary backup copies 134 would not satisfy the requirement in § 211.68(b) to maintain a backup file of data. 135
136
f. What are the “systems” in “computer or related systems” in § 211.68? 137
138
The American National Standards Institute (ANSI) defines systems as people, 139 machines, and methods organized to accomplish a set of specific functions.5 140 Computer or related systems can refer to computer hardware, software, peripheral 141 devices, networks, cloud infrastructure, operators, and associated documents (e.g., 142 user manuals and standard operating procedures). 143
144
2. When is it permissible to exclude CGMP data from decision making? 145
146
Any data created as part of a CGMP record must be evaluated by the quality unit as part 147 of release criteria (see §§ 211.22 and 212.70) and maintained for CGMP purposes (e.g., § 148 211.180). Electronic data generated to fulfill CGMP requirements should include relevant 149 metadata. To exclude data from the release criteria decision-making process, there must 150 be a valid, documented, scientific justification for its exclusion (see the guidance for 151 industry Investigating Out-of-Specification (OOS) Test Results for Pharmaceutical 152 Production, and §§ 211.188, 211.192, and 212.71(b)). The requirements for record 153 retention and review do not differ depending on the data format; paper-based and 154 electronic data record-keeping systems are subject to the same requirements. 155
156
3. Does each workflow on our computer system need to be validated? 157
158
Yes, a workflow, such as creation of an electronic master production and control record 159 (MPCR), is an intended use of a computer system to be checked through validation (see 160 §§ 211.63, 211.68(b), and 211.110(a)). If you validate the computer system, but you do 161
5 American National Standard for Information Systems, Dictionary for Information Systems, American National Standards Institute, 1991.
Contains Nonbinding Recommendations
Draft — Not for Implementation
5
not validate it for its intended use, you cannot know if your workflow runs correctly.6 For 162 example, qualifying the Manufacturing Execution System (MES) platform, a computer 163 system, ensures that it meets specifications; however, it does not demonstrate that a given 164 MPCR generated by the MES contains the correct calculations. In this example, 165 validating the workflow ensures that the intended steps, specifications, and calculations 166 in the MPCR are accurate. This is similar to reviewing a paper MPCR and ensuring all 167 supporting procedures are in place before the MPCR is implemented in production (see 168 §§ 211.100, 211.186, and 212.50(b), and the guidance for industry PET Drugs — Current 169 Good Manufacturing Practice (CGMP)). 170
171
FDA recommends you implement appropriate controls to manage risks associated with 172 each element of the system. Controls that are appropriately designed to validate a system 173 for its intended use address software, hardware, personnel, and documentation. 174
175
4. How should access to CGMP computer systems be restricted? 176
177
You must exercise appropriate controls to assure that changes to computerized MPCRs, 178 or other records, or input of laboratory data into computerized records, can be made only 179 by authorized personnel (§ 211.68(b)). FDA recommends that you restrict the ability to 180 alter specifications, process parameters, or manufacturing or testing methods by technical 181 means where possible (for example, by limiting permissions to change settings or data). 182 FDA suggests that the system administrator role, including any rights to alter files and 183 settings, be assigned to personnel independent from those responsible for the record 184 content. To assist in controlling access, FDA recommends maintaining a list of 185 authorized individuals and their access privileges for each CGMP computer system in 186 use. 187
188
If these independent security role assignments are not practical for small operations or 189 facilities with few employees, such as PET or medical gas facilities, FDA recommends 190 alternate control strategies be implemented.7 For example, in the rare instance that the 191 same person is required to hold the system administrator role and to be responsible for 192 the content of the records, FDA suggests having a second person review settings and 193 content. If second-person review is not possible, the Agency recommends that the person 194 recheck settings and his or her own work. 195
196
6 In computer science, validation refers to ensuring that software meets its specifications. However, this may not meet the definition of process validation as found in guidance for industry Process Validation: General Principles and Practices: “The collection and evaluation of data … which establishes scientific evidence that a process is capable of consistently delivering quality products.” See also ICH guidance for industry Q7A Good Manufacturing Practice Guide for Active Pharmaceutical Ingredients, which defines validation as providing assurance that a specific process, method, or system will consistently produce a result meeting predetermined acceptance criteria. For purposes of this guidance, validation is being used in a manner consistent with the above guidance documents.
7 For further discussion of such alternate control strategies, see the guidance for industry PET Drugs — Current Good Manufacturing Practice (CGMP).

5. Why is FDA concerned with the use of shared login accounts for computer 197 systems? 198
199
You must exercise appropriate controls to assure that only authorized personnel make 200 changes to computerized MPCRs, or other records, or input laboratory data into 201 computerized records, and you must implement documentation controls that ensure 202 actions are attributable to a specific individual (see §§ 211.68(b), 211.188(b)(11), 203 211.194(a)(7) and (8), and 212.50(c)(10)). When login credentials are shared, a unique 204 individual cannot be identified through the login and the system would thus not conform 205 to the CGMP requirements in parts 211 and 212. FDA requires that systems controls, 206 including documentation controls, be designed to follow CGMP to assure product quality 207 (for example, §§ 211.100 and 212.50). 208
209
6. How should blank forms be controlled? 210
211
There must be document controls in place to assure product quality (see §§ 211.100, 212 211.160(a), 211.186, 212.20(d), and 212.60(g)). FDA recommends that, if used, blank 213 forms (including, but not limited to, worksheets, laboratory notebooks, and MPCRs) be 214 controlled by the quality unit or by another document control method. For example, 215 numbered sets of blank forms may be issued as appropriate and should be reconciled 216 upon completion of all issued forms. Incomplete or erroneous forms should be kept as 217 part of the permanent record along with written justification for their replacement (for 218 example, see §§ 211.192, 211.194, 212.50(a), and 212.70(f)(1)(vi)). 219
220
Similarly, bound paginated notebooks, stamped for official use by a document control 221 group, allow detection of unofficial notebooks as well as of any gaps in notebook pages. 222
223
7. How often should audit trails be reviewed? 224
225
FDA recommends that audit trails that capture changes to critical data be reviewed with 226 each record and before final approval of the record. Audit trails subject to regular review 227 should include, but are not limited to, the following: the change history of finished 228 product test results, changes to sample run sequences, changes to sample identification, 229 and changes to critical process parameters. 230
231
FDA recommends routine scheduled audit trail review based on the complexity of the 232 system and its intended use. 233
234
See audit trail definition 1.c. above for further information on audit trails. 235
236
8. Who should review audit trails? 237
238
Audit trails are considered part of the associated records. Personnel responsible for record 239 review under CGMP should review the audit trails that capture changes to critical data 240 associated with the record as they review the rest of the record (for example, §§ 241 211.22(a), 211.101(c), 211.194(a)(8), and 212.20(d)). For example, all production and 242

Draft — Not for Implementation
7
control records, which includes audit trails, must be reviewed and approved by the 243 quality unit (§ 211.192). This is similar to the expectation that cross-outs on paper be 244 assessed when reviewing data. 245
246
9. Can electronic copies be used as accurate reproductions of paper or 247 electronic records? 248
249
Yes. Electronic copies can be used as true copies of paper or electronic records, provided 250 the copies preserve the content and meaning of the original data, which includes 251 associated metadata and the static or dynamic nature of the original records. 252
253
True copies of dynamic electronic records may be made and maintained in the format of 254 the original records or in a compatible format, provided that the content and meaning of 255 the original records are preserved and that a suitable reader and copying equipment (for 256 example, software and hardware, including media readers) are readily available (§§ 257 211.180(d) and 212.110). 258
259
10. Is it acceptable to retain paper printouts or static records instead of original 260 electronic records from stand-alone computerized laboratory instruments, 261 such as an FT-IR instrument? 262
263
A paper printout or static record may satisfy retention requirements if it is a complete 264 copy of the original record (see §§ 211.68(b), 211.188, 211.194, and 212.60). For 265 example, pH meters and balances may create a paper printout or static image during data 266 acquisition as the original record. In this case, the paper printout or static image created 267 during acquisition, or a true copy, should be retained (§ 211.180). 268
269
However, electronic records from certain types of laboratory instruments are dynamic 270 records, and a printout or a static record does not preserve the dynamic format which is 271 part of the complete original record. For example, the spectral file created by FT-IR 272 (Fourier transform infrared spectroscopy) can be reprocessed, but a static record or 273 printout is fixed, which would not satisfy CGMP requirements to retain original records 274 or true copies (§ 211.180(d)). Also, if the full spectrum is not displayed, contaminants 275 may be excluded. 276
277
Control strategies must ensure that original laboratory records, including paper and 278 electronic records, are subject to second-person review (§ 211.194(a)(8)) to make certain 279 that all test results are appropriately reported. 280
281

11. Can electronic signatures be used instead of handwritten signatures for 286 master production and control records? 287
288
Yes, electronic signatures with the appropriate controls can be used instead of 289 handwritten signatures or initials in any CGMP required record. While § 211.186(a) 290 specifies a “full signature, handwritten,” as explained in the Federal Register on 291 September 29, 1978 (43 FR 45069), part of the intent of the full signature requirement is 292 to be able to clearly identify the individual responsible for signing the record. An 293 electronic signature with the appropriate controls to securely link the signature with the 294 associated record fulfills this requirement. This comports with part 11, which establishes 295 criteria for when electronic signatures are considered the legally binding equivalent of 296 handwritten signatures. Firms using electronic signatures should document the controls 297 used to ensure that they are able to identify the specific person who signed the records 298 electronically. 299
300
There is no requirement for a handwritten signature for the MPCR in the PET CGMP 301 regulations (21 CFR part 212). 302
303
12. When does electronic data become a CGMP record? 304
305
When generated to satisfy a CGMP requirement, all data become a CGMP record. You 306 must document, or save, the data at the time of performance to create a record in 307 compliance with CGMP requirements, including, but not limited to, §§ 211.100(b) and 308 211.160(a). FDA expects processes to be designed so that quality data required to be 309 created and maintained cannot be modified. For example, chromatograms should be sent 310 to long-term storage (archiving or a permanent record) upon run completion instead of at 311 the end of a day’s runs. 312
313
It is not acceptable to record data on pieces of paper that will be discarded after the data 314 are transcribed to a permanent laboratory notebook (see §§ 211.100(b), 211.160(a), and 315 211.180(d)). Similarly, it is not acceptable to store data electronically in temporary 316 memory, in a manner that allows for manipulation, before creating a permanent record. 317 Electronic data that are automatically saved into temporary memory do not meet CGMP 318 documentation or retention requirements. 319

You may employ a combination of technical and procedural controls to meet CGMP 321 documentation practices for electronic systems. For example, a computer system, such as 322 a Laboratory Information Management System (LIMS) or an Electronic Batch Record 323 (EBR) system, can be designed to automatically save after each separate entry. This 324 would be similar to recording each entry contemporaneously on a paper batch record to 325 satisfy CGMP requirements. The computer system could be combined with a procedure 326 requiring data be entered immediately when generated. 327

13. Why has the FDA cited use of actual samples during “system suitability” or 332 test, prep, or equilibration runs in warning letters? 333
334
FDA prohibits sampling and testing with the goal of achieving a specific result or to 335 overcome an unacceptable result (e.g., testing different samples until the desired passing 336 result is obtained). This practice, also referred to as testing into compliance, is not 337 consistent with CGMP (see the guidance for industry Investigating Out-of-Specification 338 (OOS) Test Results for Pharmaceutical Production). In some situations, use of actual 339 samples to perform system suitability testing has been used as a means of testing into 340 compliance. We would consider it a violative practice to use an actual sample in test, 341 prep, or equilibration runs as a means of disguising testing into compliance. 342
343
According to the United States Pharmacopeia (USP), system suitability tests should 344 include replicate injections of a standard preparation or other standard solutions to 345 determine if requirements for precision are satisfied (see USP General Chapter <621> 346 Chromatography). System suitability tests, including the identity of the preparation to be 347 injected and the rationale for its selection, should be performed according to the firm’s 348 established written procedures and the approved application or applicable compendial 349 monograph (§§ 211.160 and 212.60). 350
351
If an actual sample is to be used for system suitability testing, it should be a properly 352 characterized secondary standard, written procedures should be established and followed, 353 and the sample should be from a different batch than the sample(s) being tested (§§ 354 211.160, 211.165, and 212.60). All data should be included in the record that is retained 355 and subject to review unless there is documented scientific justification for its exclusion. 356

14. Is it acceptable to only save the final results from reprocessed laboratory 361 chromatography? 362
363
No. Analytical methods should be capable and stable. For most lab analyses, reprocessing 364 data should not be regularly needed. If chromatography is reprocessed, written 365 procedures must be established and followed and each result retained for review (see §§ 366 211.160(a), 211.160(b), 211.165(c), 211.194(a)(4), and 212.60(a)). FDA requires 367 complete data in laboratory records, which includes raw data, graphs, charts, and spectra 368 from laboratory instruments (§§ 211.194(a) and 212.60(g)(3)). 369
370
15. Can an internal tip regarding a quality issue, such as potential data 371 falsification, be handled informally outside of the documented CGMP quality 372 system? 373
374
No. Suspected or known falsification or alteration of records required under parts 210, 375 211, and 212 must be fully investigated under the CGMP quality system to determine the 376 effect of the event on patient safety, product quality, and data reliability; to determine the 377

root cause; and to ensure the necessary corrective actions are taken (see §§ 211.22(a), 378 211.125(c), 211.192, 211.198, 211.204, and 212.100). 379
380
FDA invites individuals to report suspected data integrity issues that may affect the 381 safety, identity, strength, quality, or purity of drug products at DrugInfo@fda.hhs.gov. 382 “CGMP data integrity” should be included in the subject line of the email. 383

387
16. Should personnel be trained in detecting data integrity issues as part of a 388 routine CGMP training program? 389
390
Yes. Training personnel to detect data integrity issues is consistent with the personnel 391 requirements under §§ 211.25 and 212.10, which state that personnel must have the 392 education, training, and experience, or any combination thereof, to perform their assigned 393 duties. 394
395
17. Is the FDA investigator allowed to look at my electronic records? 396
397
Yes. All records required under CGMP are subject to FDA inspection. You must allow 398 authorized inspection, review, and copying of records, which includes copying of 399 electronic data (§§ 211.180(c) and 212.110(a) and (b)). See also section 704 of the FD&C 400 Act. 401
402
18. How does FDA recommend data integrity problems identified during 403 inspections, in warning letters, or in other regulatory actions be addressed? 404
405
FDA encourages you to demonstrate that you have effectively remedied your problems 406 by: hiring a third party auditor, determining the scope of the problem, implementing a 407 corrective action plan (globally), and removing at all levels individuals responsible for 408 problems from CGMP positions. FDA may conduct an inspection to decide whether 409 CGMP violations involving data integrity have been remedied. 410
