1Introduction
4 paragraphs
Your facility is registered with the United States Food and Drug Administration (FDA) as a manufacturer of over-the-counter (OTC) drug products. FDA has reviewed the records you submitted in response to our September 12, 2022 request for records and other information pursuant to section 704(a)(4) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) for your facility, Deqing Jiarou Daily Chemical Co., Ltd., FEI 3013042669, at Wuzling, Chengshan Village, Wukang Town, Deqing County, Huzhou, Zhejiang 313299, China.
This warning letter summarizes significant violations of Current Good Manufacturing Practice (CGMP) regulations for finished pharmaceuticals. See Title 21 Code of Federal Regulations, parts 210 and 211 (21 CFR, parts 210 and 211).
Because your methods, facilities, or controls for manufacturing, processing, packing, or holding of drugs as described in your response to our 704(a)(4) request 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)).
Following review of records and other information provided pursuant to section 704(a)(4) of the FD&C Act, significant violations were observed including, but not limited to, the following:
21. Your firm failed to conduct at least one test to verify the identity of each component of a drug product (21 CFR 211.84(d)(1).
6 paragraphs
Your firm manufactured OTC drug products including Antibacterial Hand Sanitizer (b)(4).1 Based on the records and information you provided, you did not demonstrate that you are adequately testing the identity of incoming components used in the manufacture of your drug products. You also did not demonstrate that you are testing your active ingredient ethanol for methanol.
Without adequate testing you do not have scientific evidence that your raw materials conform to appropriate specifications prior to use in the manufacture of your drug products. As a manufacturer, you have a responsibility to sample, test, and examine drug components before use in production to assure adequate quality, including testing for the presence of methanol in ethanol.
The use of ethanol contaminated with methanol has resulted in various lethal poisoning incidents in humans worldwide. See FDA’s guidance document, Policy for Testing of Alcohol (Ethanol) and Isopropyl Alcohol for Methanol, at https://www.fda.gov/media/173005/download.
2. Your firm failed to have, for each batch of drug product, appropriate laboratory determination of satisfactory conformance to final specifications for the drug product, including the identity and strength of each active ingredient, prior to release (21 CFR 211.165(a)).
Based on the records and information you provided, you did not demonstrate that you conducted adequate finished drug product testing on your drug products. For example, the certificate of analysis (COA) reports that you provided do not include an appropriate assay test for active ingredient content or impurity testing.
Full release testing, including strength and identity testing of the active ingredient, must be performed before drug product release and distribution. Without adequate testing, you do not have adequate scientific evidence to assure that your drug products conform to appropriate specifications before release.
33. Your firm failed to establish and follow an adequate written testing program designed to assess the stability characteristics of drug products (21 CFR 211.166(a)).
5 paragraphs
The records and information you provided did not demonstrate that your firm has an adequate stability program for the OTC hand sanitizer drug products that you manufacture. For example, your firm provided a stability test report which only include four weeks of stability data of (b)(4) batch of hand sanitizer. In addition, you failed to provide data demonstrating appropriate chemical and microbiological testing is performed on your drug products during your stability studies.
4. Your firm failed to establish an adequate quality control unit with the responsibility and authority to approve or reject all components, drug product containers, closures, in-process materials, packaging materials, labeling, and drug products (21 CFR 211.22(a)).
The records and information you provided demonstrate that your quality unit (QU) did not effectively exercise its responsibilities to oversee the quality of your drug manufacturing operations.
Your QU is responsible for fully exercising its authority and responsibilities. FDA is concerned that your QU may not be conducting appropriate oversight regarding CGMP operations.
See FDA’s guidance document Quality Systems Approach to Pharmaceutical CGMP Regulations for help implementing quality systems and risk management approaches to meet the requirements of CGMP regulations 21 CFR, parts 210 and 211 at https://www.fda.gov/media/71023/download.
4CGMP Consultant Recommended
1 paragraph
If your firm intends to resume manufacturing drugs for the U.S. market, you should engage a consultant qualified as set forth in 21 CFR 211.34 to assist your firm in meeting CGMP requirements before resuming drug manufacturing operations. The qualified consultant should also perform a comprehensive six-system audit of your entire operation for CGMP compliance and evaluate the completion and efficacy of all CAPAs before you pursue resolution of your firm’s compliance status per FDA’s guidance document Quality Systems Approach to Pharmaceutical CGMP Regulations.
