         SUBJECT  : Implementing Guidelines on the Collaborative Procedure for 
the Accelerated Registration of World Health Organization 
(WHO) – Prequalified Pharmaceutical Products and Vaccines  
   
 
I. BACKGROUND  4 
 5 
Republic Act No. 3720, otherwise known as the “Food, Drugs and Devices, and 6 
Cosmetics Act”, as amended  by Republic Act No. 9711, otherwise known as the “Food 7 
and Drug Administration (FDA) Act of 2009”, and its Implementing Rules and 8 
Regulations, declare that it is the policy of the state to ensure the safety, efficacy, and 9 
quality  of drug supply in the country so as to protect the health of the Filipino people. 10 
The FDA, as the national regulatory authority (NRA) in the country, together with the 11 
Department of Health (DOH), are tasked to ensure that there is (1) a constant supply of  12 
drugs, including vaccines, and (2) facilitated access to safe, effective, and quality drugs.  13 
 14 
In 2013, the World  Health Organization (WHO) issued the initial collaborative review 15 
procedure under Annex 4 of WHO Technical Report Series (TRS) No. 981, 2013. In 16 
2016, a revised procedure was issued under Annex 8 of WHO TRS No. 996. This was 17 
adopted as per Administrative Order  (AO)  No. 2020 -0044: Adoption of the 18 
Collaborative Procedure for the Accelerated Registration of World Health Organization 19 
(WHO) – Prequalified Pharmaceutical Products and Vaccines.  20 
 21 
Given the current resource constraints affecting drug regulation, co llaboration  and 22 
regulatory convergence with international organizations such as the WHO  are 23 
necessary .  24 
 25 
This Circular is  issued to guide the concerned stakeholders who will be affected by the 26 
implementation of the collaborative procedure for accelerated registration , and the 27 
activities that must be undertaken by the concerned stakeholders.  28 
 29 
 30 
II. OBJECTIVE  31 
 32 
This Circular aims to provide the implementing guidelines of AO No. 2020 -0044 which 33 
adopted the collaborative procedure for accelerated registration of WHO -prequalified 34 
pharmaceutical products and vaccines.  35 
 36 
 37 
III. SCOPE  AND COVERAGE  38 
 39 
This Circular  shall apply to all FDA -licensed drug manufacturers, traders, and 40

IV. DEFINITION OF TERMS  44 
 45 
Collaborative procedure for accelerated registration , also referred to as  46 
collaborative  review procedure  or collaborative registration procedure  (CRP ), 47 
refers to the procedure for collaboration between the WHO Prequalification Team 48 
(WHO/PQT) and interested NRAs in the assessment and accelerated national 49 
registration of WHO -prequalified pharmaceutical products and vaccines.  50 
 51 
WHO prequalified  pharmaceutical products and vaccines  refer  to those products 52 
which have undergone the WHO Prequalification  wherein comprehensive ongoing 53 
requirements  stipulated by the WHO  are applied  to ensure  that the products  are safe,  54 
efficacious,  appropriate , and meet stringent quality standards.  The mission of WHO 55 
Prequalification is to work in close cooperation with national regulatory agencies and 56 
other partner organizations to make quality priority medical products available for those 57 
who urgently need them.  58 
 59 
A national regulatory authority (NRA)  or national medicines regulatory authority 60 
(NMRA)  is responsible for ensuring that products released for public distribution  such 61 
as pharmaceuticals , biological products  such as vaccines , and medi cal devices 62 
including test kits  are evaluated properly and meet international standards of quality 63 
and safety an d efficacy.  64 
 65 
A new drug  application  refers to a registration application for a product that contains 66 
new chemical and/or biological entities proposed to be used in the diagnosis, cure, 67 
mitigation, treatment, or prevention of disease, new dosage forms, new dosage 68 
strengths, new routes of administration, and new indications. All generic products with 69 
FDA -approved equivalent shall not be considered as new drug.  70
