9月22日,FDA公布一封针对印度无菌制剂企业的警告信。主要的违规项涉及:缺少有关微生物鉴定和内毒素分析;未能建立适当的系统,来监测无菌工艺区域的环境条件,包括压差、粒子监测等。

在该警告信中,对于实验室检验,FDA特别指出:分析人员没有使用经校验的计时器(calibrated timer),来对方法中的步骤进行计时,而是使用了未经校验的挂钟(wall clock)。

Warning Letter 320-20-48
September 24, 2020
Dear Dr. Jain:
警告信320-20-48
2020年9月24日
Jain 博士:

The U.S. Food and Drug Administration (FDA) inspected your drug manufacturing facility, Panacea Biotec Limited, FEI 3007187282, at Tehsil Nalagarh, Village Malpur, Baddi, District Solan, Himachal Pradesh, from February 10 to 20, 2020.
2020年3月9日至12日,美国FDA检查了你的药品生产工厂Panacea Biotec Limited,FEI 3007187282,位于印度喜马偕尔邦。

This warning letter summarizes significant violations of current good manufacturing practice (CGMP) regulations for finished pharmaceuticals. See Title 21 Code of Federal Regulations (CFR), parts 210 and 211 (21 CFR 210 and 211).
该警告信总结了严重违反制剂CGMP规定的情况。请参阅21CFR第210和211部分。

Because your methods, facilities, or controls for manufacturing, processing, packing, or holding do not conform to CGMP, your drug products are adulterated within the meaning of section 501(a)(2)(B) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. 351(a)(2)(B).
由于你用于生产、加工、包装或储存的方法、设施或控制措施不符合CGMP,因此根据FD&C法案501(a)(2)(B)条及21 U.S.C.351(a)(2)(B) 条的规定,你的药品被认为是掺假。

We reviewed your March 13, 2020, response to our Form FDA 483 in detail and acknowledge receipt of your subsequent correspondence.
我们详细审查了你2020年3月13日对FDA 483表格的答复,并确认收到你的后续信件。

During our inspection, our investigator observed specific violations including, but not limited to, the following.
在我们的检查过程中,调查员发现了具体的违规行为,包括但不限于以下行为。

微生物鉴定问题

1. Your firm failed to establish laboratory controls that include scientifically sound and appropriate specifications, standards, sampling plans, and test procedures designed to assure that components, drug product containers, closures, in-process materials, labeling, and drug products conform to appropriate standards of identity, strength, quality, and purity (21 CFR 211.160(b)).
1.你的公司未能建立包括科学合理且适当的质量标准、标准、取样计划和检验程序在内的实验室控制措施,以确保组件、药品容器、密封件,在制品、标签和药品符合相关规定,即鉴别、强度、质量和纯度的标准(21 CFR 211.160(b))。

Your firm lacked data on microorganism identification from your aseptic processing operation.
你的公司缺少无菌工艺操作中有关微生物鉴定的数据。

Your microbiology laboratory is responsible for identifying microorganisms recovered from your firm’s environmental monitoring (EM) program. Your procedure, Isolation and Identification of Microbial Isolates SOP BFI-QC-060 Rev No. 02, requires identification of isolates to the genus (and “preferably” species) level when they are considered to be morphologically different from previously identified isolates.
你的微生物实验室负责鉴定从公司的环境监测(EM)程序中回收的微生物。你的程序“微生物分离物的分离和鉴定SOP BFI-QC-060 Rev. 02”,要求将分离物鉴定为属(“最好”是种)水平,前提是它们在形态上不同于先前鉴定的分离物。

However, you rarely identified microbes recovered from your aseptic processing operation and lacked meaningful data on microbes in your aseptic processing room. Notably, in 2019, your firm identified only one organism of the 6360 microorganisms isolated from the ISO 7 area.
但是,你很少鉴别从无菌工艺操作中回收的微生物,并且缺乏有关无菌工艺室中微生物相关的有意义数据。值得注意的是,在2019年,对于ISO 7级洁净室中分离出的6360个微生物,你的公司仅鉴别了其中一种。

Furthermore, you attempted to visually “identify” recovered microorganisms using an incomplete and crude photographic library consisting of only (b)(4) microbes.
此外,你尝试目视“鉴别”回收的微生物,这一过程中使用了不完整且粗糙的仅由XX个微生物组成的照片库。

n addition to lacking microbial identification data from aseptic processing operations, your laboratory also failed to maintain basic microbial differentiation information. For example, you often failed to record bacterial gram stain data, determine whether microbes were sporeformers, or provide other critical differentiating data.
除了缺乏来自无菌工艺操作的微生物鉴定数据外,你的实验室还无法维护基本的微生物分化信息。例如,你经常无法记录细菌革兰氏染色数据,无法确定微生物是否为产孢子菌,也不能提供其它重要的区分数据。

Routine characterization of recovered isolates provides vital data to promptly detect potential routes of contamination in aseptic operations and take action to prevent sterile drug contamination. Because your firm lacks microbial identification data from environmental monitoring, you lack basic information needed to evaluate the ongoing state of control of your aseptic manufacturing operations.
对回收的分离物进行常规表征可提供重要数据,以迅速检测出无菌操作中潜在的污染途径,并采取措施防止无菌药物污染。你的公司缺少来自环境监测的微生物鉴别数据,因此你缺少评估无菌生产操作的持续控制状态所需的基本信息。

Your response stated that you would differentiate and attempt to presumptively identify environmental isolates based on colony morphology. In addition, you stated you would perform a gram stain on isolates recovered from your ISO 5 and 7 areas. Your response is inadequate. You did not commit to identifying all isolates recovered throughout your aseptic processing rooms to at least the genus level (and species, whenever possible).
你的答复表明,你将根据菌落形态,区分并尝试推测性地鉴定环境分离株。此外,你还说过要对从ISO 5和7区域回收的分离物进行革兰氏染色。你的回应不充分。对于在整个无菌工艺室所有分离株,你并没有承诺中至少鉴定出属(以及可能的种)的。

Also, you did not commit to implement a sufficient microbial identification program for ancillary cleanrooms. For ancillary cleanrooms, identification of isolates should occur at an adequate frequency to provide a current database of microflora, and other isolates from these areas should be differentiated with higher specificity than your procedures currently prescribe.
另外,你没有承诺为辅助洁净室实施足够的微生物鉴定程序。对于辅助洁净室,应该以足够的频率对分离株进行鉴定,以提供当前的菌群数据库,并且应该以比你目前规定的程序更高的特异性,来区分来自这些区域的其它分离株。

Endotoxin Analysis 内毒素分析
During the inspection, we observed the analysis of water samples and (b)(4) samples for endotoxin using the gel clot method. We observed that the analyst failed to perform the critical steps for vortexing samples. Additionally, the analyst failed to use a calibrated timer for timing the steps in the method and instead used a wall clock that had not been calibrated. Vortexing and timing are critical steps for this method to ensure that testing does not yield false negative results. Your gel clot method also failed to include sufficient instructions.
在检查过程中,我们观察到了使用凝胶凝结法分析水样品和XX样品中的内毒素。我们观察到分析人员未能执行涡旋样品的关键步骤。此外,分析人员没有使用已校验的计时器,来对方法中的步骤进行计,而是使用了未经校验的挂钟。涡旋和定时是该方法的关键步骤,以确保检验不会产生假阴性结果。你的凝胶凝结法也没有包含足够的说明。

your procedure to include vortexing steps, as well as use a calibrated external thermometer and a calibrated external timer. You also stated that, as a part of your investigation to assess impact on the product, you analyzed reserve samples of all commercial batches of (b)(4) injection (b)(4) mg/vial and all batches complied with the acceptance criteria.
你的回答承认你的方法不充分,你将修改程序以包括涡旋步骤,并使用已校验的外部温度计和已校验的外部计时器。你还声明,作为评估对产品影响的调查的一部分,你分析了XX注射剂XX mg /瓶的所有商业批次的留样,所有批次均符合可接受标准。

Your response is inadequate. You failed to perform a retrospective review of your laboratory practices including but not limited to the adequacy of your test methods. You also did not provide an evaluation of analyst competencies and training sufficiency.
你的回应不充分。你没有对实验室实践进行回顾性审查,包括但不限于检验方法的充分性。你也没有提供对分析人员能力和培训充分性的评估。

In response to this letter, provide the following:
针对此信,请提供:

• A comprehensive, independent assessment of your laboratory practices, procedures, methods, equipment, documentation, and analyst competencies. Based on this review, provide a detailed plan to remediate and evaluate the effectiveness of your laboratory system. Areas of special emphasis in your retrospective assessment and corrective action and preventive action (CAPA) plan should include, but not be limited to:
•对你的实验室操作、程序、方法、设备,文档和分析人员的能力进行全面、独立的评估。在此审查的基础上,提供详细计划,以补救和评估实验室系统的有效性。在回顾性评估以及纠正和预防措施(CAPA)计划中,应特别强调的领域应包括但不限于:

o Review all laboratory test methods to ensure they are well-defined in order to enable reproducibility, and remediate any gaps in specificity that are identified
o复查所有实验室检验方法,确保其定义明确,以确保可重复性,并弥补任何确定的特异性差距

o Ensure adequate calibration frequencies for lab equipment (e.g., heating block thermometer). Include your SOP with remediated frequencies
o确保实验室设备(例如加热块温度计)具有足够的校验频率。提供含频率修改后的SOP

环境监测
2. Your firm failed to establish an adequate system for monitoring environmental conditions in aseptic processing areas (21 CFR 211.42(c)(10)(iv)).
2.你的公司未能建立适当的系统,来监测无菌工艺区域的环境条件(21 CFR 211.42(c)(10)(iv))。

Your firm manufactures (b)(4) injection (b)(4)mg/vial for the U.S. market. Our inspection revealed deficient ongoing monitoring and control of your aseptic processing facility.
你的公司为美国市场生产XX注射剂,XX毫克/瓶。我们的检查发现,你的无菌工艺设施缺乏持续的监测。

Pressure Differentials压差
You lacked an effective system to ensure adequate control of differential pressures in your aseptic processing facility. You manually recorded differential pressures between cleanrooms approximately (b)(4) during a (b)(4).
你缺乏有效的系统,来确保对无菌工艺设施中压差进行适当控制。你手动记录洁净室压力差为XX。

You also allowed excursions up to (b)(4), including pressure reversals. Notably, for excursions beyond (b)(4), a deviation/incident “may” be proposed.
你还允许XX范围的偏移,包括反向压力。值得注意的是,对于超出XX的偏移,“可能”会启动偏离/事件程序。

You also lacked an adequate, integrated system for frequently recording room differential pressure during a (b)(4), scrutinizing ongoing HVAC control, initiating deviations, and taking appropriate actions when pressure excursions occur.
你还缺少一个足够的集成系统,无法在XX期间频繁记录房间压差,仔细持续检查HVAC控制,并在发生压力偏移时启动偏差,采取适当的措施。

Because of your inadequate pressure differential systems, and insufficient standards for initiating investigations of pressure control issues, you lack evidence that ongoing control was maintained for the HVAC systems used in your aseptic processing operations.
由于压差系统不足,并且没有足够的标准来启动对压力控制问题的调查,因此,你缺乏证据证明:对无菌工艺操作中使用的HVAC系统保持了持续控制。

A suitable facility monitoring system is critical to maintain appropriate air quality throughout all of your cleanrooms. All alarms and deviations from established limits should be appropriately investigated to rapidly detect atypical changes that can compromise the facility’s environment. Prompt detection of an emerging low-pressure problem is essential to preventing ingress of lower quality air into a higher criticality room.
合适的设施监测系统,对于在所有洁净室中保持合适的空气质量,至关重要。对所有警报和偏离既定限值的情况,应进行适当调查,以迅速检测出可能危害设施环境的非典型变化。及时发现新出现的低压问题,对于防止低质量空气进入较高级别的关键房间,是至关重要的。

Your response stated you are implementing a new system that focuses on monitoring online differential pressures for the (b)(4) (filling line). However, you did not commit to a comprehensive review of your facility monitoring and HVAC systems to improve environmental control in all cleanrooms of the aseptic processing facility.
你的回答表明你正在实施一个新系统,该系统专注于监测XX(灌装线)的在线压差。但是,你并未承诺对设施监测和HVAC系统进行全面审查,针对无菌工艺设施所有洁净室,来改善环境控制。

Non-Viable Particulate Monitoring粒子监测
You lacked an adequate system for handling non-viable particulates (NVP) above your action level of (b)(4) NVP ≥ 0.5 μm/ftᶾ during aseptic processing operations.
对于悬浮粒子(NVP),你没有足够的系统,处理无菌工艺操作中高于行动限NVP≥0.5μm/ftᶾ的情况。

This limit was exceeded for seven out of (b)(4) batches of (b)(4) injection mg/vial manufactured since May 2019. You lacked investigations in response to the high particulate levels observed in the ISO 5 aseptic processing operation. Per your NVP monitoring procedure, an investigation was not required unless an excursion lasted longer than (b)(4).
对于自2019年5月生产的X批注射剂,有七批超限。对于ISO 5无菌工艺操作中发现的高粒子水平,你缺乏调查。根据你的NVP监测程序,除非偏移持续的时间长于XX,否则无需进行调查。

Excessive particulates in the ISO 5 environment can lead to nonviable or biological contamination of sterile drug products.
ISO 5级环境中的粒子过多,会导致无菌药品的颗粒或微生物污染。

In your response, you stated that you are in the process of evaluating the feasibility of implementing an integrated non-viable particulate counter within the (b)(4) which will enable the filling machine to stop when an excursion occurs.
在答复中,你说明,你正在评估在XX中实施集成的粒子计数器的可行性,该计数器将使灌装机在发生偏移时停止运行。

Although you have committed to improvements in your non-viable particulate monitoring program, you lacked sufficient information on the parameters that trigger investigations.
尽管你一直致力于改善粒子监测程序,但是你缺乏有关触发调查参数的足够信息。

Based upon the nature of the violations we identified at your firm, we strongly recommend engaging a consultant, qualified as set forth in 21 CFR 211.34, to assist your firm in meeting CGMP requirements.
根据我们在你公司中发现的违规行为的性质,我们强烈建议雇用一名符合21 CFR 211.34规定的合格顾问,以帮助你的公司满足CGMP要求。

Your use of a consultant does not relieve your firm’s obligation to comply with CGMP. Your firm’s executive management remains responsible for resolving all deficiencies and systemic flaws to ensure ongoing CGMP compliance.
你聘用顾问并不能免除公司遵守CGMP的义务。你公司的执行管理层仍然负责解决所有缺陷和系统性缺陷,以确保持续符合CGMP。

结论
The violations cited in this letter are not intended to be an all-inclusive list of violations that exist at your facility. You are responsible for investigating and determining the causes of these violations and for preventing their recurrence or the occurrence of other violations.
本信函中引用的违规行为并非旨在列出与你产品相关的所有违规行为。你有责任调查和确定这些违规的原因,并防止其再次发生或发生其它违规情况。

If you are considering an action that is likely to lead to a disruption in the supply of drugs produced at your facility, FDA requests that you contact CDER’s Drug Shortages Staff immediately, at drugshortages@fda.hhs.gov, so that FDA can work with you on the most effective way to bring your operations into compliance with the law. Contacting the Drug Shortages Staff also allows you to meet any obligations you may have to report discontinuances or interruptions in your drug manufacture under 21 U.S.C. 356C(b). This also allows FDA to consider, as soon as possible, what actions, if any, may be needed to avoid shortages and protect the health of patients who depend on your products.
如果你考虑采取的行动可能会导致你药物的供应中断,则FDA要求你立即联系CDER的药物短缺人员(drugshortages@fda.hhs.gov),以便FDA可以与你以最有效的方式沟通,使你的运营符合法律规定。根据21 USC 356C(b),与药品短缺人员联系,还可以使你履行报告药品供应中断的义务。这也使FDA可以尽快考虑可能需要采取什么措施,以避免短缺,并保护依赖你产品的患者的健康。

Until you correct all violations completely and we confirm your compliance with CGMP, FDA may withhold approval of any new drug applications or supplements listing your firm as a drug manufacturer.
在你完全纠正所有违规行为、且我们确认你遵守CGMP之前,对于新药申请或补充申请,FDA可能会拒绝批准将你的公司列为药品生产商。

Failure to correct these violations may also result in the FDA refusing admission of articles manufactured at Tehsil Nalagarh, Malpur Baddi, District Solan, Himachal Pradesh, into the United States under section 801(a)(3) of the FD&C Act, 21 U.S.C. 381(a)(3). Articles under this authority may be subject to refusal of admission, in that the methods and controls used in their manufacture do not appear to conform to CGMP within the meaning of section 501(a)(2)(B) of the FD&C Act, 21 U.S.C. 351(a)(2)(B).
根据FD&C法案21 801(a)(3)条与USC 381(a)(3) 条,不纠正这些违规行为也可能导致FDA拒绝接纳该工厂生产的产品,无法进入美国。对于该法案授权下的产品,可能会被拒绝入境,因为其生产使用的方法与控制不符合CGMP,CGMP是在FD&C法案21(501)(a)(2)(B) 条与USC 351(a)(2)(B) 条中被要求的。

After you receive this letter, respond to this office in writing within 15 working days. Specify what you have done since our inspection to correct your violations and to prevent their recurrence. If you cannot complete corrective actions within 15 working days, state your reasons for delay and your schedule for completion.

内毒素保温仪器一般都自带计时器,那么这个仪器经过确认合格就表明时钟审核准确的。也许印度这家公司采信的是室内外挂钟,由此联系生产车间计时如何控制;

压差的持续监控,是否是必须的和强制的要求?有无相关的规范和指南?采用什么样的系统,监控哪些功能间?FDA没有给出相应的指南。
