As pharmaceutical supply chains become more globalized and complex, regulatory oversight increases as well in complexity, on top of an increasing need for financial and technical resources. It is, therefore, strategic to establish regulatory reliance and cooperation practices among national regulatory authorities, in order to address individual regulatory gaps in a more efficient and effective manner. With the issuance of Administrative Order (AO) No. 2020-0045, entitled, “Establishing Facilitated Registration Pathways for Drug Products, including Vaccines and Biologicals”, the Food and Drug Administration (FDA) recognized that instituting good reliance practices would be impactful toward facilitating access to drugs by producing more efficient regulatory mechanisms.

The World Health Organization, in its Technical Report Series No. 1033, Annex 10 – Good reliance practices in the regulation of medical products: high-level principles and considerations, defines reliance as “the act whereby the regulatory authority in one jurisdiction takes into account and gives significant weight to assessments performed by another regulatory authority or trusted institution, or to any other authoritative information, in reaching its own decision. The relying authority remains independent, responsible, and accountable for the decisions taken, even when it relies on the decisions, assessments, and information of others.”

In applying regulatory reliance, the FDA shall be streamlining its regulatory review to accelerate the registration process of drug products by leveraging against product regulatory assessments made by reference drug regulatory agencies (RDRAs). Simultaneously, strengthened post-marketing surveillance shall ensue and continuous improvement in building FDA’s institutional capacity to effectively oversee innovative and complex advancements of drug products shall remain in the long term. Thus, pursuant to Republic Act (RA) No. 3720 as amended by RA No. 9711, the FDA hereby provides the implementation arrangements for the abridged and verification review pathways stipulated in AO No. 2020-0045 through this Circular as a pragmatic approach to institutionalizing regulatory reliance.


This Circular aims to provide the implementing guidelines of AO No. 2020-0045 on the facilitated registration pathways (FRPs) through abridged review or verification review of new drugs, including vaccines and biologicals.


This Circular covers applications of new drugs including vaccines, and biologicals as defined in Section IV below, and shall apply to all licensed drug distributors intending to place in the local market or apply for post-approval changes of drug, vaccine, and biological products with existing and valid approval/s from RDRA/s.

This Circular only covers the abridged review and verification review types of FRP. For the collaborative procedure under AO No. 2020-0044 or the Adoption of the Collaborative Procedure for the Accelerated Registration of World Health Organization (WHO) – Prequalified Pharmaceutical Products and Vaccines, the implementing guidelines shall be covered by a separate Circular.


Abridged review refers to a limited independent assessment of specific parts of the dossier, or submission for suitability of use under local conditions and regulatory requirements while relying on prior assessment from an RDRA to inform the local decision. The review is based on a complete assessment report, including question and answer documents, and the dossier including the stability data.

Verification review refers to an assessment process by which the submission has been evaluated and approved by at least two (2) RDRAs, and the FDA only validates the submission and ensures that the product conforms to the registration conditions, standards, and requirements as approved by the RDRAs.

A new drug application refers to a local registration application for a product that contains new chemical and/or biological entities proposed to be used in the diagnosis, cure, mitigation, treatment, or prevention of disease, new dosage forms, new dosage strengths, new routes of administration, and new indications. All generic products with FDA-approved equivalents shall not be considered new drugs.

Reference Drug Regulatory Agency (RDRA) refers to a national or regional regulatory agency for drugs, vaccines, and biologicals being relied upon by the FDA for a more efficient approach at arriving at a decision thereby improving and expediting quality assured, effective, and safe products.

Assessment Report refers to the complete, unredacted, or unedited copy of the assessment reports of the marketing authorization application and evaluated by the RDRA. The Assessment Report details and explains how the RDRA assessed the safety, quality, and efficacy data and information within the submitted dossier to inform its final decision on the regulatory action. The Assessment Report outlines the area of concerns, questions and answers, and clarifications which the RDRA raised and how these were addressed by the applicant and includes the product approval conditions, the final and approved product labeling, and all other annexes.


A. Eligibility Criteria

The eligibility criteria provided under Sec. IV.B of AO No. 2020-0045, reiterated with necessary clarifications as follows, shall apply to applicants availing of the FRP:

  2. The applicant may avail of the following submission pathways, subject to certain conditions.
    a. Abridged review may be availed when the drug product, vaccine, or biological has been approved by an RDRA and the product application is within three (3) years from the date of approval of the RDRA.
    b. Verification review may be availed when the drug product, vaccine, or biological has been approved by at least two (2) RDRAs and the product application is within three (3) years from the date of approval of the RDRA/s.
    c. The applicant may choose to avail of only one (1) type of FRP per application based on compliance with the requirements. If the requirements of any of the FRP cannot be complied with, the application shall be processed following the regular review pathway.

  1. The eligible product shall be the same as the product duly approved or registered in the RDRA/s identified by the applicant.
    a. All aspects of the drug product’s quality, including but not limited to the formulation, manufacturing site/s, release and shelf-life specifications, and primary packaging, must be the same as those currently approved by the identified RDRA/s at the time of submission.
