Republic Act No. 9711, otherwise known as the “Food and Drug Administration (FDA) Act of 2009,” and its Implementing Rules and Regulations has declared the policy of the state to adopt, support, establish, institutionalize, improve and maintain structures, processes, mechanism and initiatives that are aimed, directed and designed to: (a) protect and promote the right to health of the Filipino people; (b) help establish and maintain an effective health products regulatory system; and (c) undertake appropriate manpower development and research responsive to the country’s health needs and problems.

In 2020, the FDA worked on an streamlined regulation for the conduct of clinical trials in the Philippines. This effort resulted in the publication of Administrative Order (AO) No. 2020-0010, otherwise known as “Regulations on the Conduct of Clinical Trials for Investigational Products,” approved and implemented on 06 March 2020.

The World Health Organization (WHO) supports the implementation of reliance on other regulators’ work as a general principle in order to make the best use of available resources and expertise (WHO Technical Report Series, No.1033, 2021 (Annex 10, Good reliance practices in the regulation of medical products: high level principles and considerations). This principle enables leveraging the output of others whenever possible while placing a greater focus at the national level on value-added regulatory activities that cannot be undertaken by other authorities, such as in-country vigilance and clinical trial activities. Reliance approaches facilitate timely access to safe, effective, and quality-assured medical products and can help in regulatory preparedness and response, particularly during public health emergencies.

Good Reliance Practices are anchored in the overarching Good Regulatory Practices (GRP) which provide a means for establishing sound, affordable and effective regulation of medical products as an important part of health system strengthening. If implemented effectively, GRP can lead to consistent regulatory processes, sound regulatory decision-making, increased efficiency of regulatory systems and better public health outcomes.

In relation to these, the FDA, as the National Regulatory Authority (NRA), recognizes that reliance will further streamline its review process and accelerate the conduct of clinical trials in the country. The existing regulations related to the conduct of clinical trials were streamlined to create a clear, simplified and transparent regulation, boost local competitiveness, and attract more local and foreign entrepreneurs.


This Circular provides guidelines on reliance for approval of clinical trial applications and to promote a more efficient and effective approach to the regulations in the oversight of the conduct of clinical trials in the Philippines. Specifically, this Circular aims to:

A. To facilitate the evaluation of clinical trial applications addressing public health emergencies, rare diseases, cancer, HIV/AIDS, and emerging and re-emerging infectious diseases of public health threats.

B. To improve the access of investigational drug products for public health emergencies, rare diseases, cancer, HIV/AIDS, and emerging and re-emerging infectious diseases of public health threats


This Circular shall apply to Sponsors, Contract Research Organizations (CRO), investigators and  Research Ethics Committees (RECs) involved in the approval, conduct, monitoring and inspection, in all phases of Multi-Regional Clinical Trials (MRCTs) for investigational drug products intended for eventual product registration and marketing.


To ensure a common understanding of concepts and clarity in the interpretation of the terms used in this Circular, the definitions listed in this section are from AO No. 2020-0010, International Council for Harmonization (ICH) Guidelines (E6 & E17), and/or modified from the WHO Technical Report Series, No.1033, 2021.

A. Abridged Regulatory Pathways: Regulatory procedures facilitated by reliance, whereby the regulatory decision is solely or partially based on the application of reliance. The review of a clinical trial application wherein the process or progress of the review and decision-making will be expedited.

B. Contract Research Organization (CRO): A person or an organization (commercial, academic, or other) contracted by the sponsor to perform one or more of a sponsor’s trial-related duties and functions.

C. Regulatory Reviewer: An individual, organization, or institution duly recognized by the FDA to assist in the review of the technical and scientific soundness, merit, and regulatory compliance of a clinical trial application and provide recommendation.

D. Multi-Regional Clinical Trial (MRCT): A clinical trial conducted in more than one country/region under a single protocol.

E. Orphan drug: Any drug or medicine used to treat or alleviate the symptoms of persons afflicted with a rare disease and declared as such by the DOH upon recommendation of the National Institutes of Health (NIH), as defined in Republic Act No. 10747 also known as Rare Disease Act of the Philippines.

F. Reference Drug Regulatory Agency (RDRA): A stringent regulatory authority whose regulatory decisions and/or regulatory work products are relied upon by another regulatory authority to inform its own regulatory decisions. The list of RDRAs is provided under Annex A of this Circular, subject to regular updating.

G. Reliance: The act whereby the regulatory authority in one jurisdiction takes into account and gives significant weight to assessments performed by another regulatory authority in reaching its own decision.

H. Sponsor: An individual, company, institution, or organization that takes responsibility for the initiation, management, and or financing of clinical trial.


A. General Guidelines

1. Licensed Sponsor/CRO intending to undertake clinical trials under an abridged pathway shall follow the rules, regulations, and standards provided in A.O. No. 2020-0010, “Regulations on the Conduct of Clinical Trials for Investigational Products”, and the guidelines specified herein.

2. The FDA retains its prerogative on the following, for clinical trials under abridged pathway specially when there is a significant impact on the safety or physical or mental integrity of the subjects and scientific value of the trial:
a. To assess applications and apply judgements that consider the applicability of the assessment outcomes of the identified RDRA together with its benefits and risks as applicable in the Philippine context. In case of differences, such as in target population, epidemiology, and other features of the disease, concomitantly used medicines and other factors that can substantially affect the benefit–risk profile of an investigational product, appropriate justification should be provided upon filing of application.
b. To exempt a study from local Good Clinical Practice (GCP) inspection when an RDRA has conducted an inspection of the reliance-related study
c. To rely on generated information and relevant clinical decisions of RDRA on the reliance-related studies for FDA’s own regulatory decision.

3. The FDA remains independent, responsible, and accountable for the following decisions taken, even when it relies on the decisions, assessments and information of others.

4. Only establishments with valid FDA-issued Licenses to Operate (LTOs) as Sponsor and/or CRO can apply for abridged review.

5. The abridged procedures for Clinical Trial applications shall be applied only if all of the following criteria are met:
a. The investigational product will address any of the following:
i. Public health emergency
ii. Rare disease (Orphan drug)
iii. Cancer
iv. Human Immunodeficiency Virus (HIV)/Acquired Immunodeficiency Syndrome (AIDS)
v. Emerging or re-emerging infectious diseases considered as public health threat

b. All aspects of the clinical trial application, including but not limited to the protocol and investigational product information, are identical to that currently approved by the identified RDRA at the time of submission.
