The guidance describes how the FDA will request and conduct voluntary remote interactive evaluation at facilities. The guidance outlines specific considerations for planning, conducting and concluding a remote interactive evaluation as well as discusses impacts on established commitments and timeframes. The FDA may request to conduct a remote interactive evaluation for many purposes and programs whenever a program office determines it is appropriate based on mission needs and any travel limitations. This policy applies to all drug inspection programs including, but not limited to:


  • Pre-Approval Inspections (PAIs) and Pre-License Inspections (PLIs)
  • Post-Approval Inspections (PoAIs)
  • Surveillance Inspections
  • Follow-Up and Compliance Inspections
  • Bioresearch Monitoring (BIMO) Inspections


The policy described in the guidance is intended to remain in effect only for the duration of the public health emergency related to COVID-19 as declared by the Secretary of Health and Human Services (HHS) on January 31, 2020.


Coronavirus (COVID-19) Update: FDA Outlines Inspection and Assessment Activities During Pandemic, Roadmap for Future State of Operations (May 2021)


The FDA issued a new report titled, “Resiliency Roadmap for FDA Inspectional Oversight,” outlining the agency’s inspectional activities during the COVID-19 pandemic and its detailed plan to move toward a more consistent state of operations, including the FDA’s priorities related to this work going forward. The main contents of the report are as follows:


  • The report highlights the number of mission-critical inspections and prioritized domestic inspections conducted, as well as inspections that the agency was unable to complete during the past year. 
  • The report outlines the FDA’s continued successful use of alternative tools and approaches where inspections were or are not currently feasible, including remote interactive evaluations.
  • The report further outlines the ongoing steps the agency is taking in order to resume standard operational levels of inspection activities.
  • The agency will also soon begin a multi-year modernization effort to further transform data enterprise platforms and cross-program interoperability infrastructure to better support innovation related to its regulatory oversight role.
  • The FDA is also establishing an agency-wide FDA Inspectional Affairs Council that will plan and coordinate inspectional activities.


FDA Emergency Use Authorization for Vaccines to Prevent COVID-19 (May 2021)


This guidance is issued by the FDA on May 25, 2021 and supersedes the guidance of the same title issued on February 22, 2021 and October 2020. The guidance aims to provide sponsors of requests for Emergency Use Authorization (EUA) for COVID-19 vaccines, with recommendations regarding the data and information needed to support the issuance of an EUA under section 564 of the FD&C Act (21 U.S.C. 360bbb-3) for an investigational vaccine to prevent COVID-19 for the duration of the COVID-19 public health emergency. 


The guidance gives instructions on the criteria and considerations for the issuance of an EUA, the key logistic recommendations for the request for an EUA, and the prioritization of requests for issuance of an EUA, as well as recommendations regarding regulatory, Chemistry, Manufacturing and Controls (CMC), safety and effectiveness information and data to be included in a request for an EUA for a COVID-19 vaccine. The guidance also lays out the considerations for continuing clinical trials following issuance of an EUA and the consideration of an EUA for a COVID-19 vaccine by an FDA advisory committee. Additionally, the appendixes provide instructions on the submission of information in preparation for a Vaccines and Related Biological Products Advisory Committee (VRBPAC) meeting, and detailed instructions on the evaluation of vaccines to address emerging SARS-CoV-2 variants.


Bispecific Antibody Development Programs Guidance for Industry (May 2021)


This guidance discusses unique aspects for chemistry, manufacturing, and controls (CMC), as well as nonclinical and clinical development programs for bispecific antibodies that are different from monoclonal antibody development programs. The guidance also addresses a range of general, regulatory and scientific considerations and provides recommendations regarding the type of data necessary to support the approval of bispecific antibodies.


For regulatory considerations, the FDA’s regulation on fixed-combination prescription drugs for humans (21 CFR 300.50) does not apply to the development of bispecific antibodies, which are single molecules. Although not generally expected, in some cases the FDA may request a comparison of the bispecific antibody to an approved monospecific product(s) directed against the same antigenic target(s) to inform the benefit-risk assessment of the bispecific antibody.


Q3D (R2) – Guideline for Elemental Impurities (Draft: May 2021)


ICH Q3D “Elemental Impurities” is a quality guideline for the control of elemental impurities in new drug products (medicinal products), and it establishes Permitted Daily Exposures (PDEs) for Elemental Impurities (EIs) for drug products administered by the oral, parenteral and inhalation routes of administration. The initial version of Q3D was finalized under Step 4 in November 2014.


The current version of Q3D (R2), published by the FDA in May 2021, is a draft version which was endorsed on September 25, 2020 and is currently under public consultation. This document is comprised of extracts of the Q3D (R2) Guideline made from the revisions to the Q3D (R1) Guideline. The extracts are as follows: Part 1 – Extract of Appendix 2: Correction of PDEs for Gold, Silver and Nickel; Part 2 – Extract of Appendix 3: Correction of Gold monograph; Part 3 – Extract of Appendix 3: Correction of Silver monograph; and, Part 4 – New Appendix 5. The revised draft guideline incorporates Permitted Daily Exposure (PDE) for new elemental impurities (EI) / routes of administration and revises the PDE for EI already listed in Q3D (R1) as new toxicological data becomes available.


Q12 Technical and Regulatory Considerations for Pharmaceutical Product Lifecycle Management Guidance for Industry (May 2021)


This guidance provides a framework to facilitate the management of post-approval chemistry, manufacturing, and controls (CMC) changes in a more predictable and efficient manner. 


This guidance applies to pharmaceutical drug substances and products (both chemical and biological) that require a marketing authorization and to drug-device combination products that meet the definition of a pharmaceutical or biological product. Changes needed to comply with new or revised pharmacopoeial monographs are not within the scope of this guidance. The harmonized regulatory tools and enablers are given below:


  • Categorization of Post-approval CMC Changes 
  • Established Conditions
  • Post-approval Change Management Protocol
  • Product Lifecycle Management Document
  • Pharmaceutical Quality System and Change Management
  • Relationship Between Regulatory Assessment and Inspection
  • Structured Approaches for Frequent CMC Post-approval Changes
  • Stability Data Approaches to Support the Evaluation of CMC Changes


Effective implementation of the tools and enablers with associated guiding principles will enhance the management of post-approval changes and transparency between industry and regulatory authorities, promote innovation and continual improvement.


Q12 Technical and Regulatory Considerations for Pharmaceutical Product Lifecycle Management Annexes (May 2021)


This document comprises two parts: (1) Illustrative Examples (Annex I) and (2) Structured Approach to Analytical Procedure Changes (Annex II). The examples provided in sections I.A through I.F of the ICH Q12 Annex I are mock examples provided for illustrative purposes. They only suggest how the tools described in sections III, IV, and V of the ICH Q12 guidance could be applied and should not be used as a template or the sole basis for a regulatory submission. In addition, the reporting categories, as described in section II of the ICH Q12 guidance, may differ across regions depending on regional legislation; the nature of the product; and the Marketing Authorization Holder’s (MAH’s) demonstrated understanding of the product, process, and analytical procedure. 


MAHs are expected to maintain existing analytical procedures for authorized products and ensure that these are kept up-to-date. The intent of the approach provided in Annex II is to incentivize structured implementation of at least equivalent analytical procedures that are fit for purpose. An approach wherein specific criteria are defined for changes to analytical procedures used to test marketed products is described.


Chemistry, Manufacturing, and Controls Changes to an Approved Application: Certain Biological Products (June 2021)


This guidance is intended to assist applicants and manufacturers of certain licensed biological products in determining which reporting category is appropriate for a change in chemistry, manufacturing, and controls (CMC) information to an approved biologics license application (BLA). Licensed biological products that are within the scope of this guidance and of particular interest include vaccines, allergenic products, plasma-derived products and their recombinant analogs, and cellular and gene therapy products.


The guidance describes general and administrative information on evaluating and reporting changes and recommendations for reporting categories based on a tiered-reporting system for specific changes under 21 CFR 601.12. Special considerations regarding change in process parameters and change in a supplier of raw materials are given. In the Appendix, the FDA provides a list of examples of post-approval manufacturing changes and recommended reporting categories. Particularly, the FDA suggests that ICH Q12 guidance should be used by applicants in concert with any other applicable FDA guidance to report post-approval changes to the Agency when such reporting is required by the statute and regulation. 


This guidance finalizes the draft guidance, “Chemistry, Manufacturing, and Controls Changes to an Approved Application: Certain Biological Products” dated December 2017, and supersedes the guidance entitled “Guidance for Industry: Changes to an Approved Application: Biological Products” dated 1997 (July 1997 guidance).

Changes in Biological Products 


Post-marketing Changes in Biological Products


The Center for Drug Evaluation (CDE) issued the “Technical Guideline on Post-marketing Chemistry, Manufacturing and Controls Changes in Biological Products, Trial” (hereinafter referred to as “the Technical Guideline”). The Guideline provides suggestions on evaluating and reporting post-marketing changes in chemistry, manufacturing and controls (CMC), as well as studies and data required to support the changes in biological products. The Marketing Authorization Holder (MAH) is the main responsible entity for managing post-marketing changes, and a supplementary application should be submitted to the agency when MAH changes. Key considerations of comparability study are also provided in the Guideline. Relevant guidelines and requirements such as the ICH guideline shall also be considered when applying this guidance.   


Changes are categorized into three classes based on the risk of potential impacts on the safety, efficacy and quality of biological products. 


  • Minor changes (Type I): Changes that have hardly any impact on the safety and efficacy related quality attributes of the biological products. Minor changes can be reported through Annual Reports.
  • Moderate changes (Type II): Changes that may have moderate impact on the safety and efficacy related quality attributes of the biological products. Relevant studies are required to demonstrate that the changes do not negatively impact the quality, safety, and efficacy of the biological products. Moderate changes should be recorded to the provincial drug administrations, where the MAH is located for domestically manufactured biological products and be recorded to the CDE for biological products manufactured abroad.
  • Major changes (Type III): Changes that may have significant impact on the safety and efficacy related quality attributes of the biological products. Extensive studies are required to demonstrate the changes do not negatively impact product quality, safety, and efficacy. Supplementary application to the National Medical Products Administration (NMPA) is required and the changes cannot be implemented before approval. 


Changing During the Review Period of Drug Registration Application


The CDE issued the “Work Procedures for Changes During the Review Period of Drug Registration Application (Draft Guidance)” (hereinafter referred to as “the Procedures”). The Procedures apply to changes that occur during the review of the clinical trial application (CTA), supplemental application, Biological License Application (BLA) and re-registration application. In principle, the applicant can only apply once for the changes, and the proposed changes do not affect the evaluability of the original application. In addition, technical changes are not accepted during the review process of the CTA and supplemental application during the clinical trial due to the limited review and approval timeline.

The NMPA issued the “Provisions of the Drug Inspection, Trial” (hereinafter referred to as “the Provisions”), which went into effect on the day of its promulgation. The Provisions stipulates the main responsibilities for regulatory authorities of all levels, inspection categories and procedures, as well as requirements for the authority and inspector. 


The NMPA is responsible for the management of drug inspections across the country, supervising and guiding the provincial medical products administrations to carry out on-site inspections of drug MAHs and manufacturers. The Center for Food and Drug Inspection (CFDI) of the NMPA is responsible for inspections of vaccines and blood products.



“Good Pharmacovigilance Practices” (hereinafter referred to as “the Practices”) will come into effect on December 1, 2021. The MAHs and the drug registration applicants who were approved to conduct clinical trials (hereinafter referred to as “the applicants”) should establish a special pharmacovigilance agency within China to develop an annual periodical analysis and evaluation plan based on the marketing time, risk characteristics or requirements of regulatory authorities and carry out the work as planned. The MAHs and the applicants should complete information registration in the National Adverse Event Surveillance System within 60 days of promulgation.


For the drug registration applicant, the drug safety update report (DSUR) during research and development (R&D) should be submitted to the CDE regularly after the clinical trial is approved. 


For the MAH, adverse drug reaction (ADR) monitoring data, clinical studies, literature and other data should be evaluated regularly. The MAH should record and report Periodic Safety Update Report (PSUR) as required. Serious adverse events should be reported no later than 15 days after information is obtained, and non-serious adverse reactions should be reported no later than 30 days after information is obtained. If the adverse event occurs abroad, the MAH should submit an individual case safety report (ICSR) to the National Center of ADR Monitoring. If a drug is required to be suspended for sale or use, or is withdrawn from the market by an overseas regulatory agency, the MAH should report to the national regulatory agency and National Center of ADR Monitoring within 24 hours after receiving the information.

Common Q&A about For-inspection Drugs


  • Q1:For the APIs and drug products applications submitted before the implementation of the new “Provisions for Drug Registration,” commercial scale process validation was not conducted before nor required upon submission. Thus, the on-site inspection application cannot be submitted to respond to the notice of inspection. 


    • The questions are: 


(1) When to submit the inspection application? 

A: In accordance with the previous “Provisions for Registration of Drug Products”, the applicant should submit the inspection application within 6 months upon receipt of the CDE notice.


(2) When is the deadline for the inspection? 

A: The CFDI should start the inspection within 30 days after the applicant submits the inspection application.

(3) How to submit the process validation materials? 

A: In accordance with the previous requirements, the PPQ batch numbers are required to be included in the application form, while process validation materials and other relevant documents can be provided to the inspection team during on-site inspection.

(4) Do all the products manufactured after the critical batches need to be preserved?

A: Yes. Samples should be kept for future inspection.


  • Q2: Will dynamic or static inspections be notified in advance? 


A: The CFDI will notify the applicant in advance if dynamic production is needed during the inspection. Normally, no phone notice will be given for static inspections. The applicant should check the inspection information through the “Window for Drug Registration Applicants”. 


  • Q3: Which department should the corrective materials for the inspection be submitted to?


A: For inspections conducted after the implementation of the new “Provisions for Drug Registration,” the correction reports of the defects should be submitted to the provincial medical products administration(s) for review. 

  • Q4: For products under regular review, the inspection report should be returned to the CDE 40 days before the end of the 200-day review cycle. For products under priority review, should the report be returned to CDE 40 days before the end of the 130-day review?


A: The inspection report of products under priority review should be returned to CDE 25 days before the end of the 130-day review cycle.\
