A panel discussion involving the regulators was preceded by keynote presentations giving an update on the current approaches used by US FDA, EMA, MHRA, and PIC/S for remote/distant inspections.



Alonza Cruse
Director, Office of Pharmaceutical Quality Operations

In his keynote presentation, Cruse said that although on-site inspections remained the “gold standard,” the pandemic had forced FDA to rethink its approach to inspections by using a risk-based approach involving various oversight tools, including remote assessment of records, information sharing with trusted regulatory partners, reviewing compliance history of manufacturing facilities, analytical testing, and remote interactive evaluation (RIE) of facilities by video/live streaming of operations. Guidance for RIE was introduced in April 2021.1 FDA used the term “Remote Interactive Evaluation” to distinguish a remote evaluation from an on-site inspection.

Cruse said that the RIE would be hosted by FDA using an FDA version of MS Teams, Zoom, or Adobe as the IT platform. A written list of observations would follow the remote evaluation, but FDA would not issue Forms 482, Notice of Inspections and Forms 483, Inspectional Observations.

Cruse said that once the pandemic was over, FDA would go back to on-site inspections but would likely use a hybrid approach by considering at least a RIE component and remote inspection of records.

FDA may use remote evaluation outcomes to decide on the acceptability of a facility for a pending application, to determine a future cGMP surveillance inspection timing and scope, and to help resolve a “for cause” need to inspect. FDA will not use remote evaluation in lieu of an inspection.

Looking ahead, FDA will continue to leverage and maximize every available tool including operationalizing RIE. Relationships with capable regulatory partners will be enhanced.


Brendan Cuddy
Lead Scientific Officer

In his presentation, Cuddy said that the pandemic had created a challenge to GMP inspectors who needed to ensure ongoing verification of GMP compliance was being maintained. EMA recognized the need for regulatory flexibility until the end of the pandemic, using approaches such as automatic extension of the validity dates for GMP certificates and product-specific GMP flexibility for crucial medicines and process validation.

Cuddy said that a distant assessment guidance document to directly verify GMP compliance had been developed and published in October 2020 by EMA.2 This guidance document defined “distant assessment” as well as guidance for the planning, preparation, conduct, and post-assessment phases of the distant assessment.

Cuddy said distant assessments have broad application and can be performed for all types of sites, dosage forms, and preapproval inspections. They can result in the granting of GMP certificates, but with the certificate indicating that the determination was based on a remote assessment. He emphasized that a distant assessment does not replace an on-site inspection, which should be conducted when circumstances permit. He said that if a distant assessment does not permit the granting of a GMP certificate, a clock-stop would be triggered until an on-site inspection was possible.

For new sites or for pre-approval inspections, Cuddy said if any critical deficiencies were identified, the relevant application would be paused until an on-site inspection could be performed. For other types of distant assessments, if any critical deficiencies were identified, a statement of non-compliance may be issued.

Cuddy concluded by saying that distant assessment has proven to be a useful tool in the supervisory toolbox . He said good positive feedback had been received from inspectors and inspected companies on the conduct and results of distant assessments to date. Distant assessments provide an additional control measure to verify compliance. The future will see more international authority use of distant assessment, but distant assessment will not replace on-site inspection.

Looking ahead, FDA will continue to leverage and maximize every available tool including operationalizing RIE. Relationships with capable regulatory partners will be enhanced.


David Churchward
Head of Operations Quality, Compliance and External Affairs

Churchward discussed current and future challenges arising from the pandemic. Current challenges include severe travel restrictions, global supply pressures, and the backlog of GMP inspections. Future challenges when the pandemic is over would likely include the development of regulatory approaches to a digital environment and the harmonization of remote assessments between regulators to create an environment of reliance.

Churchward asked whether the regulatory changes arising from the pandemic are here to stay, including remote assessments. It was his belief that because a distant assessment was a rapid and flexible monitoring tool, it would continue to be used after the pandemic, but in a hybrid form, particularly for low-risk situations. He stressed that collaboration between regulatory agencies had been very good during the pandemic, and he advocated for this to continue and increase with opportunities taken to harmonize approaches and potentially regulations for distant assessments leading to more reliance between agencies. He mentioned that PIC/S has a key role in facilitating future closer cooperation and mutual reliance.


Anne Hayes
Inspection Manager, Compliance and PIC/S Chair

PIC/S is an informal cooperative scheme that had been operating for 50 years, comprising 54 member authorities from all over the world (including countries in Europe, Africa, the Americas, Asia, and Australasia). Membership in PIC/S enables member authorities to share information of GMP-related topics, including GMP inspection reports. The mission for PIC/S is “To lead the international development, implementation and maintenance of harmonized GMP standards and quality systems of inspectorates in the field of medicinal products.”3

Hayes said that PIC/S held a training seminar for inspectors each year, with the most recent seminar in December 2020 covering the topic of distant assessment. This seminar revealed that because the terminology used for on-site assessments varied among member authorities, there was a need for harmonization of terminology.

Hayes said that seminar participants indicated their strong support for the development of guidelines and tools to harmonize procedures for distant inspections in order to facilitate continued reliance between international regulatory partners. She said that PIC/S had formed a working group to commence work on the preparation of these guidelines, tools, and training.

Panel Discussion

A two-hour panel discussion with all the regulators followed, moderated jointly by Thomas Hartman, ISPE President and CEO, and Thomas Zimmer, ISPE Vice President, European Operations.

Here is a summary of main points from the panel discussion.

Criteria for Distant Assessments

In response to a question regarding criteria for choosing different approaches, all panelists agreed that a risk-based approach was taken. Cruse said that because of the COVID-19 health emergency, FDA limited unnecessary face-to-face contact by conducting prioritized domestic on-site inspections only for those situations that were deemed “mission critical,” which included manufacturers of breakthrough therapies, unmet medical needs, etc. The term “mission critical” was defined in an FDA Guidance document covering Q&As.4

Cuddy said that EMA confers with the relevant supervisory authority and the rapporteurs for the product concerned to decide on the need for an on-site inspection, with the criticality of the product also taken into account.

Gouws said that each regulatory authority has their own procedures to determine when to carry out on-site inspections. She said that WHO had developed a guidance document on conducting pre-qualification inspections remotely.5

Preparation and Performing

All panelists said that as with on-site inspections, the key elements for distant assessments were transparency, integrity of data, complete and accurate data, truthfulness, and ease of access to subject matter experts (SMEs). Cruse said that there was evidence that some companies were selective with the information they shared; e.g., not all OOS data was shared, resulting in FDA needing to probe deeper and to ask repeatedly for information.

Eichmueller, Delbò, Morenas, and Lorente agreed that although hybrid inspections were being done in Europe, the German, Italian, French, and Spanish health authorities always preferred to do on-site inspections. Distant assessments do not provide sufficient assurance of compliance and take more resource for preparation and conducting, they said. It was considered that anything done remotely was simply an assessment and not an inspection. On-site inspections were necessary for critical products.

Morenas said that it was necessary to establish how to manage and protect the flow of information received during distant assessments. Cuddy confirmed that cybersecurity is not a new topic; both sides, agencies and industry, need to invest in security to help prevent cyberattacks.

Gouws said that it was important for WHO to know which other regulatory authorities are planning to carry out a distant assessment of specific manufacturing sites so that WHO can request a joint distant assessment. She said that this approach was appreciated by industry. She also said that industry can help to facilitate distant assessments by sharing data well in advance of the distant assessment, having suitable translators available, and having the company representative supported by suitable numbers of company staff in the war room, including plentiful technical SMEs.


Churchward said that as legislation in the UK did not dictate that GMP inspections must be on-site, MHRA can use other methods to determine GMP compliance. He added that where MHRA had seen enough information to give confidence of GMP compliance, a GMP certificate would be issued, but this certificate would bear a note to indicate that it was based on a remote assessment. Other EU agencies also confirmed that GMP certificates were being issued based on distant assessments, but that a suitable annotation was included.

Shestakov said that the Russian regulatory authority had never stopped issuing GMP certificates during the pandemic. He said that in order to avoid drug shortages in Russia, legislative changes had been made to enable remote assessments to be carried out, and GMP certificates could be issued following such assessments.


Hayes said that the pharmaceutical industry in Ireland had indicated to HPRA its strong support for distant assessments. She confirmed that distant assessments required a significant amount of preparation by regulatory authorities and because of this, it was advisable for companies to conduct a review of their IT capabilities, including digital tools and bandwidth because a regulatory authority cannot do a remote assessment if a site is unable to do video streaming effectively.

Shestakov said that from April 2020, the Russian regulatory authority had conducted 300 remote assessments, with some of the sites found not ready to receive the remote assessment because the inspectors could not get to the deepest manufacturing areas. He said that companies need to build the infrastructure to receive the remote assessment, including suitable video cameras; also, inspectors and manufacturing staff need suitable training about remote assessments.

To conduct remote inspections, it is imperative that some technical requirements are met, e.g., to ensure a secure communication channel by using private virtual networks. Keys and/or coded streaming of video and audio information should be shared in advance, preferably with the use of secure real-time transport protocol (SRTP). When it comes to using smartphones, there are prescribed requirements for smartphone’s camera and protection class. In addition, it is preferable that smartphones have a portable tripod or other anchorage that ensures simultaneous use of smartphones and back-lighting lamps. Availability of a portable spare battery is important.

Comparing On-site and Distant Assessments

With regard to potential differences between on-site inspections and distant assessments, Churchward said that MHRA had done an analysis to see if there was any difference in the number and type of deficiencies found. He said that this study had found no significant differences; this included quality system and facility failures, which trended much the same. Also, for hybrid inspections there were no significant differences.

In contrast, Eichmueller said that the German regulatory authorities had found fewer operational deficiencies during distant assessments, which is another reason why they should not be considered comparable to on-site inspections.

Sharing Information Among Health Authorities

Rosa said that FDA had been sharing inspection information under the EU mutual recognition agreement (MRA) for some years now; this was even more important and relevant at this time of the COVID-19 pandemic. He said that the challenge was that sometimes the scope of the inspection information shared may be different than what is required by FDA. Cruse added that in addition to the EU MRA, FDA also obtains information from EU and PIC/S member authorities about inspections carried out in other countries. Cuddy said that EU was using inspection reports from other regulatory authorities, including PIC/S member authorities.

All panelists stressed the need for sharing of information through mutual reliance with PIC/S regulatory partners to support distant assessments and the relevant outcome; however, each agency was making its own decisions. Where present, MRAs are different from “information sharing” and do not extend to distant assessments.

Hayes said that PIC/S had introduced a guidance document on “Inspection Reliance” in 2018,6 which has been instrumental in facilitating the sharing of inspection information among PIC/S member authorities at a time when on-site inspections had been significantly curtailed during the pan-demic.


Cuddy admitted that even within Europe, there was some disagreement among regulators about terminology for the terms distant, remote, and desktop inspection assessment.

Hayes said that one of the action items arising from the virtual PIC/S Committee meeting held during the previous week was to request International Coalition of Medicines Regulatory Authorities (ICMRA) to formulate a reflection paper on remote/distant assessment, which would include the harmonization of terminology, and for PIC/S to develop harmonized procedures for remote/distant assessments. She admitted that as terminology around re-mote/distant assessments was used in different ways by different regulatory authorities, it may be difficult for ICMRA to harmonize the terminology.

The Future of Distance Assessment

Each panelist provided their thoughts for the future about the use of distant assessments. FDA, EMA, MHRA, and 28% of respondents in a PIC/S survey believed that there was a place for distant assessments in the future, potentially using hybrid ways of working. However, all panelists agreed that a distant assessment cannot substitute for a face-to-face on-site inspection.

Regulators from France, Germany, Italy, and Spain said that the distant assessment was only an emergency tool and cannot replace a face-to-face on-site inspection. The distant assessment has many shortcomings and provides less information, and, because of this, on-site inspections should resume as soon as possible. Morenas and Eichmueller said that maybe a distant assessment could be used for low-risk situations only.

For Russia, Shestakov said that distant assessments were an interim measure only but could still be used in the future under special circumstances. He said that it was likely that the hybrid model would be used in the future. Gouws said distant assessments may be used by WHO as a tool for training in the future.
