2月9日，FDA公布一封针对美国本土企业(Allay Pharmaceuticals)的警告信，主要的缺陷项涉及工艺验证、OOS调查、稳定性数据等问题。
FDA表示，对于某个验证批，时隔一年之后，该公司才启动长期稳定性研究（2020年5月1日），而这一决定刚好发生在FDA检查（2020年5月5日）开始前的几天。另外，对于某API，该公司的含量检验结果与供应商COA之间存在明显差异（相差7.8％），但公司没有进行充分的评估；这说明对于来自供应商物料，质量部门未能执行充分的监督。
最后，FDA指出，该公司质量部门未能履行其职责，以确保所生产的药品符合GMP要求，并建议使用CGMP顾问，来解决公司质量问题。
稳定性数据缺陷
3. Your firm failed to establish and follow an adequate written testing program designed to assess the stability characteristics of drug products and to use results of stability testing to determine appropriate storage conditions and expiration dates (21 CFR 211.166(a)).
你们公司未能建立并遵循适当的书面检验程序，以评估药品的稳定性特征；未能使用稳定性检验结果，来确定适当的储存条件和有效期(21 CFR 211.166(a))。
Your stability program is inadequate. You failed to have adequate long-term stability data to support the commercial size validation batches manufactured using API from a new supplier. Also, you failed to follow your stability test protocol by not consistently performing disintegration testing. The validation batches using the new API supplier were manufactured from May 16 to June 25, 2019, but not placed into a long-term stability study until May 1, 2020, almost a year later.
你们的稳定性程序不足。你们没有足够的长期稳定性数据，来支持使用新供应商API生产的商业验证批次。另外，你们没有遵循稳定性测试方案，因为没有一致性地执行崩解检验。使用新API供应商的验证批次于2019年5月16日至6月25日生产，但直到将近一年后的2020年5月1日才进行长期稳定性研究。
Stability data is critical for ensuring that products maintain their identity, strength, quality, purity, and safety throughout their labeled shelf-lives.
对于确保产品效期内保持其鉴别、强度、质量、纯度和安全性，稳定性数据至关重要。
In your response, you indicated that you initiated a deviation investigation for the lack of stability testing and that these deficiencies will not reoccur. A stability coordinator will also be hired to oversee the stability program.
在你们的答复中，你们表示由于缺乏稳定性测试而发起了偏差调查，并且这些缺陷将不会再次发生。还将聘请稳定协调员来监督稳定计划。
Your response is inadequate because you did not provide interim measures to address the products in the market that are lacking long term stability data.
你们的答复不充分，因为你们没有提供中期措施，来解决缺乏长期稳定性数据的市售产品问题。
In response to this letter, provide the following:
在针对此信的答复中，提供如下信息：
· A comprehensive, independent assessment and CAPA plan to ensure the adequacy of your stability program. Your remediated program should include, but not be limited to:
全面、独立的评估和CAPA计划，以确保你们的稳定性计划是充分的。你们的补救计划应包括但不限于：
o Stability indicating methods
稳定性指示方法
o Stability studies for each drug product in its marketed container-closure system before distribution is permitted
在分销之前，对市售容器密闭系统中的每种药物进行稳定性研究
o An ongoing program in which representative batches of each product are added each year to the program to determine if the shelf-life claim remains valid
正在进行的计划，每年将每种产品的代表性批次添加到其中，以确定有效期声明是否仍然有效
o Detailed definition of the specific attributes to be tested at each station (timepoint)
每个点(时间点)要检验的特定属性的详细定义

质量部门未履行职责
4. Your firm’s quality control unit failed to exercise its responsibility to ensure drug products manufactured are in compliance with CGMP, and meet established specifications for identity, strength, quality, and purity (21 CFR 211.22).
4.质量控制部门未能履行职责，以确保所生产的药品符合CGMP要求，并符合有关鉴别、强度、质量和纯度的既定质量标准(21 CFR 211.22)。
Your quality unit (QU) failed to adequately oversee the quality of components received from your supplier and your drug manufacturing operations. For example:
对于来自供应商和药物生产部门组分的质量，你们质量部门(QU)未能进行充分的监督。例如：
· The variability in API assay results reported by your supplier compared to your testing was not adequately evaluated. The variability observed may compromise the assay and content uniformity of your finished product. For example, your firm’s test results for API lot (b)(4), used in the manufacture of (b)(4) tablets (b)(4) lot (b)(4), had a difference of 7.8% from the API manufacturer’s certificate of analysis (COA). Your firm used your assay result to formulate the finished product. Additionally, the FDA sampled lot (b)(4) and the sample results failed to meet the USP assay specification for active ingredient, (b)(4), and for content uniformity. In your communication dated September 15, 2020, your firm indicated that this lot was not distributed and will be destroyed.
·对于供应商API分析结果与检验结果之间的差异，你们没有充分评估。这种差异性可能会影响成品的含量和含量均匀性。例如，对XX片剂XX批次XX的生产中使用的API批次XX，相比于与API生产商的分析证书(COA)，你们的检验结果相差了7.8％。你们使用你们的含量结果来生产成品。此外，FDA对批次XX进行了其他部分，样品结果不符合USP中API XX的含量和含量均匀性的质量标准。在你们2020年9月15日的沟通信件中，你们公司表示该批次并未分销，将被销毁。
Per the quality agreement with (b)(4), your firm is responsible for the qualification of approved manufacturers. However, during the inspection you had not qualified the new API supplier and you relied on (b)(4) to perform qualification of the supplier, which is contrary to the agreement.
根据与XX达成的质量协议，你们公司负责确认生产商资质。但是，在检查过程中，你们没有确认新的API供应商资质，而是依靠XX对供应商进行资质确认，这违反了协议。
· Computerized systems in the laboratory had inadequate controls.
·实验室中的计算机系统控制不充分。
· Complaints were not adequately reviewed and investigated.
·投诉未得到适当的审查和调查。
In your response you stated that your firm recognizes the need to have more interactions with the API manufacturer. You committed to investigating and communicating to the API manufacturer when API release testing results differ more than 3%. Additionally, you have contacted the manufacturer of your HPLC systems to purchase and validate the necessary equipment. You also indicated that your new complaint procedure includes tracking, trending, and evaluating complaints.
在你们的答复中，你们表示认识到需要与API生产商进行更多的交互。你们承诺：在API放行检验结果相差超过3％时，启动调查并与API生产商沟通。此外，你们已经与HPLC系统的生产商联系，以购买和验证必要的一起。你们还指出，新的投诉程序包括跟踪、趋势化分析和评估投诉。
Your response is inadequate. You did not describe when and how you will requalify your API supplier or provide justification for how you determined when differences in API assay need to be investigated. In addition, you did not perform a retrospective review of the test results for your previous API supplier, (b)(4). Also, you did not perform an assessment to determine the risk from failing to have audit trail enabled controls and unique user passwords.
你们的答复不充分。你们没有描述何时、以及如何重新确认API供应商资质，就何时启动API分析差异调查，也没有提供论证。此外，就以前API供应商XX检验结果，你们没有对进行回顾性审查。此外，对于未能启用审计追踪和使用唯一用户/密码，你们没有执行评估来确定其风险。

未经批准的新药 (略)
作为合同方的责任
Responsibilities as a Contractor
Drugs must be manufactured in conformance with CGMP. FDA is aware that many drug manufacturers use independent contractors such as production facilities, testing laboratories, packagers, and labelers. FDA regards contractors as extensions of the manufacturer.
药品必须按照CGMP生产。FDA意识到许多药品生产商使用独立的合同方，例如生产设施、检验实验室、包装商和贴标签商。FDA将合同方视为生产商的延伸。
You and your customer (b)(4) have a quality agreement regarding the manufacture of (b)(4). You are responsible for the quality of drugs you produce as a contract facility regardless of agreements in place with product owners. You are required to ensure that drugs are made in accordance with section 501(a)(2)(B) of the FD&C Act for safety, identity, strength, quality, and purity.
就与XX产品的生产，你们和客户XX签订了质量协议。无论与产品所有者达成何种协议，作为合同设施生产，你们应对生产的药品质量负责。你们需要确保按照FD＆C法案第501(a)(2)(B)节的规定生产药物，以确保安全性、鉴别、强度、质量和纯度。
