4. Maintain and scale-up a sustainable and affordable collaborative registration procedure for diagnostics and support national regulatory bodies to make use of it to streamline their national regulatory procedures.
5. Develop and disseminate clearer procurement guidance for countries regarding the proposed and suggested remaining shelf-life of molecular diagnostic tests.
6. Expedite release of recent clinical and service delivery diagnostics-related guidance and recommendations in Q2 of 2021.
17. Develop and implement a sustainable and affordable collaborative registration procedure for diagnostics in 2019 and support national regulatory bodies to make use of it to streamline their national regulatory procedures.
18. Subject to support from donors (see 16 above), reinforce the capacity of its Prequalification of In Vitro Diagnostics programme, so that additional staffing can help to optimise process efficiencies and support transparent and predictable timelines for the review of HIV diagnostic products (in particular EID and VL products, and in alignment with WHO guidance).
19. In order to facilitate reduction of national evaluation studies (see points 9 and 12 above), provide relevant additional information within the public reports of products achieving prequalification status for increased data sharing to countries.
20. Provide additional guidance and support implementation on post-market surveillance and quality assurance to manufacturers, countries, and national regulatory authorities.
21. Develop guidelines and tools to support multiplexing of diagnostic technologies as well as viral load frequency for pregnant and breastfeeding women and children and consider novel interventions with patient impact evidence for review in next guidance review processes, including upgrading the POC EID recommendation.
The collaborative registration procedure for IVDs is being further extended in 2020.
The 2nd draft of the guideline document: Collaborative procedure between the World Health Organization (WHO) and National Regulatory Authorities in the assessment and accelerated national registration of WHO-prequalified In Vitro Diagnostics (IVDs), has been prepared to facilitate timely access to WHO-prequalified products in countries, to ensure that the product in countries is the same as the one which is WHO-prequalified and to provide a model for regulatory information exchange between countries. The document has undergone 2 rounds of public consultation and is on-track to be published by the end of the year.
One additional country (Ghana) has joined the CRP for IVD pilot.
A workshop was held with participants from the national regulatory authority in Uganda to support the facilitated registration of HIV self-tests. A second workshop is planned with the Mozambique NRA later in October.
The CRP-IVD pilot was implemented in 2019 in 5 countries. The procedure is being further extended in 2020 whereby WHO will be working with 7 countries to support the facilitated registration of HIV self-tests. The CRP-IVDs guidelines are published for public consultation.
The pilot is ongoing, all 5 pilot countries have signed the CRP agreement with WHO and the manufacturer is filing the submissions in each country. By end of 2019 we will be able to draw conclusions on the experience with the pilot.
To date no additional resources were made available to PQT/IVD, although discussions following transformation and RPQ relocation study included needed resources and phased prioritization of recruitments. PQDx timelines are transparent; - published a guidance on timelines on their website.
Regulators and end-users of IVDs in three sub-regions have been trained:
• Sub-regional work shop for Anglophone Africa in Arusha (2016)
• Sub-regional workshop for Francophone Africa in Dakar (2017)
• Sub-regional workshop for Russophone countries in Minsk (2018)
• National workshop in Ukraine (2018).
A replacement for a staff who left in 2019 is coming on board in November 2020. Beyond this, any additional resources are subject to approval by DG.
PQ Public reports have been amended and include extensive additional information to assist countries in leveraging PQ assessment outcomes. In Q3 2020 PQT will also split the current Public Report into two reports; the WHOPAR will capture the dossier assessment and performance evaluation outcomes and the WHOPIR will outline the site inspection findings.
The PQ public report was adjusted to provide more data on performance evaluations. At the next GDWG meeting this will be discussed again and input from GDWG will be sought.
The WHO normative guidance on post-market surveillance of in vitro diagnostics is available in English, French and Russian. A 2-day workshop that describes how to implement the guidance exists in each of the languages. There is no current HQ funding for these activities; however, additional funds are being sought to support further post-market surveillance trainings and workshops.
An amendment to the ‘Improving the quality of HIV-related point-of-care testing: ensuring the reliability and accuracy of test results’ handbook is ongoing to support improved quality assurance with POC NAT
WHO (HIV and TB) co-convened in July 2019 a global meeting with ASLM including 15-20 countries and key stakeholders in diagnostics to identify concrete ways to improve and increase access to integrated multiplex technologies, to determine how they can be translated into public health policy, and ultimately have global patient impact. The integration toolkit developed from this meeting will ideally be released by the end of 2019.
An amendment to the ‘Improving the quality of HIV-related point-of-care testing: ensuring the reliability and accuracy of test results’ handbook is ongoing to support improved quality.
