1. Introduction

1.1 Overview

This guidance document, outlines Health Canada's expectations for sponsors of clinical trials involving drugs, and provides direction on voluntary the submission of a Sex- and Gender-Based Analysis Plus (SGBA Plus) Demographics Action Plan (DAP), where applicable.

The SGBA Plus DAP is intended to support inclusive clinical trial practices and ensure that sex, gender, and intersecting demographic factors are appropriately considered throughout the trial lifecycle. Submission of a DAP is not a regulatory requirement but is strongly encouraged, to support inclusive trial design.
The recommendations described in this guidance are non-binding and provided for guidance purposes only, and do not create new legal requirements under the proposed Clinical Trials Regulations.

1.2 Scope and application

This guidance document is intended for sponsors conducting, or planning to conduct, clinical trials involving the use of drugs (pharmaceuticals, biologics, or radiopharmaceuticals).

In the Food and Drugs Act (FDA) a clinical trial is defined as a study, involving human subjects, for the purpose of discovering or verifying the effects of a drug, device, or food for a special dietary purpose. 

This guidance document outlines key considerations for the following phases of clinical trials:

This guidance document does not apply to the following:

These considerations represent encouraged approaches and suggested best practices; they do not create new regulatory requirements. Health Canada encourages the adoption of inclusive best practices in all clinical trials where applicable, as they are essential to both scientific validity and ethical responsibility. Ensuring representation of participants from various racial, ethnic, sex, gender, age and socioeconomic backgrounds and more can enhance generalizability of trial results and provide insights into real-world drug effectiveness.Footnote 1

1.3 Policy objectives

This document is intended to assist sponsors seeking authorization to conduct clinical trials in Canada by outlining recommended expectations related to adequate representation of trial participants. It aims to promote inclusive research practices and support equitable drug development across diverse populations in Canada.

Specifically, this document:

This guidance also reflects Health Canada's commitment to SGBA Plus - an analytical and intersectional framework adopted across the Government of Canada's Health Portfolio.

SGBA Plus is used to assess how different factors (such as sex, age, gender, race, ethnicity, indigeneity, disability, and more) affect how Canadians experience federal health initiatives. It helps Health Canada formulate responsive and inclusive health research, surveillance, legislation, policies, regulations, programs and services by considering factors that contribute to differences in accessing health-related resources and health outcomes.

In addition, this guidance document supports Health Canada's SGBA Plus Action Plan which aims to strengthen the systematic integration of sex, gender and diversity considerations throughout Health Canada's work to advance equity, diversity and inclusion.

1.4 Policy statements

The purpose of this Guidance is to:

1.5 Background

Limited diversity in clinical trial participation can compromise the breadth, relevance and applicability of biomedical research findings.Footnote 2 Historically marginalized populations—including women, older adults, racialized and ethnically diverse groups, individuals identifying beyond the binary gender spectrum, and persons with disabilities—are frequently underrepresented across various therapeutic domains.Footnote 2

This underrepresentation can result in constrained datasets, diminished confidence from excluded communities, and underpowered subgroup analyses.Footnote 3 Consequently, prescribing practices may fail to account for population-specific safety and efficacy signals, thereby exacerbating health inequities and limiting the benefits of evidence-based interventions.Footnote 2

A review of trials registered in ClinicalTrials.gov from 2000-2020 found that 80 percent of participants identified as White.Footnote 4 This underscores the need for recruitment strategies that reflect disease burden across ethnicities and other relevant demographic variables—so that that representation aligns with incidence, prevalence, and outcomes of target conditions.Footnote 3

While average treatment effects may suffice to gauge general estimations of drug effectiveness, failure to include diverse populations can obscure critical safety signals.Footnote 3

In some cases, these safety concerns have emerged decades after approval, demonstrating the real-world implications of trial homogeneity. Table 1 highlights several examples where delayed identification of safety concerns had specific implications for ethnically diverse populations:

African Americans were found to be more prone to experiencing angioedema in 1996. Warnings added in 2014. 15 years
(Source:Footnote 3 Anand SS et al., BMJ 2025; 388:e082485. doi:10.1136/bmj-2024-082485)

Inclusion of demographically diverse trial participants enables more robust subgroup analyses and facilitates more comprehensive assessments of safety and therapeutic effectiveness. It also deepens insight into how symptoms and treatment results differ among groups, supports more equitable prescribing practices, and enhances public trust in the regulatory system.

To support more inclusive and patient-centered research, sponsors are encouraged to thoughtfully consider demographic and identity-related factors relevant to the intended population for their investigational product. Such an approach fosters greater transparency, promotes informed decision-making, and contributes to improved outcomes while helping to advance equity in healthcare.

2. Regulatory context

2.1 The clinical trials regulations

As part of the regulatory requirements set out in the proposed Clinical Trials Regulations, pursuant to section 11(2)(e), sponsors must submit a protocol as part of the application to enable the Minister to determine whether authorization should be granted. Section 1(1) defines the protocol as a document describing the objectives, design, methodology, study population, statistical considerations, and organization of a clinical trial.

In alignment with these provisions, section 46(1)(b) requires that a clinical trial be conducted in accordance with Good Clinical Practices (GCP), including by ensuring that the study population of the clinical trial be consistent with the objectives of the trial.

Building on this regulatory foundation,and Health Canada's commitment to evidence-based decision-making, sponsors are encouraged to submit a Sex- and Gender-Based Analysis Plus (SGBA Plus) Demographics Action Plan as part of all applicable regulatory submissions. This recommendation while not regulatory requirement, underscores the importance of designing and conducting clinical trials with a comprehensive understanding of the diverse characteristics of the population for whom the health product is intended.

This recommendation supports a methodical and inclusive approach to trial participant recruitment, which takes into account the stage of drug development, the specific objectives of the clinical study, and the underlying epidemiology of the disease or condition under investigation. By doing so, sponsors ensure that the data generated are reflective of real-world use and can be generalized to the broader target population.

Health Canada encourages the integration of SGBA Plus principles throughout the clinical development process. This includes the systematic consideration of intersecting demographic factors such as sex, gender identity, race, ethnicity, age, disability, and more and other relevant determinants of health. These variables have the potential to influence pharmacokinetics, pharmacodynamics, clinical outcomes, and patient safety profiles, and must therefore be thoughtfully integrated into study design, participant eligibility criteria, and analytical plans.

Incorporating SGBA Plus demographic considerations contributes to the generation of high-quality, reliable data that are representative and equitable, ultimately supporting improved health outcomes across diverse population groups.

2.2 Submitting a SGBA plus demographics action plan

Submission of a SGBA Plus Demographics Action Plan (DAP) is optional. When provided, it should be in accordance with Health Canada's standard procedures for electronically filing regulatory submissions in either Electronic Common Technical Document (eCTD) format or non-eCTD format.

Sponsors should refer to the following guidance documents, as applicable:

The SGBA Plus DAP may be submitted within Module 1.7.1 Study Protocol. Sponsors can choose to submit the plan either as an embedded section within the clinical trial protocol or as a standalone document. Sponsors are encouraged to clearly state in the cover letter accompanying the submission whether a SGBA Plus DAP is included, and identify its exact location within the application to facilitate review.

It is anticipated that information pertaining to the SGBA Plus DAP will overlap and be reflected in multiple other sections of Module 1, where contextually appropriate.

Examples of relevant subsections include:

SGBA Plus demographic information overlapping within these sections—such as epidemiological data, clinical population characteristics, and disease pathophysiology literature—contributes to a more cohesive and transparent presentation of demographic inclusivity within the proposed clinical trial framework.

Submission of Comparative Inclusion Plans in Support of SGBA Plus DAPs

Health Canada will also consider other equivalent inclusive strategies or recruitment plans—such as Diversity Action Plans or Inclusive Clinical Trial Recruitment Strategies— that have been previously submitted to other regulatory authorities, provided they sufficiently address expectations in this guidance.

Sponsors are encouraged to reference such submissions within the cover letter and include the relevant documentation in Module 1.7.1 Study Protocol, either appended to the clinical trial protocol or presented as a separate, stand-alone document.

2.3 Omission of a SGBA plus demographics action plan

Health Canada strongly encourages Sponsors to provide a SGBA Plus Demographics Action Plan whenever feasible. In circumstances where submission of such a plan is not applicable, sponsors are encouraged to provide a clear explanation of the extent to which the following apply:

Any explanation provided may be supported by relevant data and evidence. Sponsors are encouraged to clearly articulate the rationale underlying their proposed enrollment targets.

This justification may be submitted either as a stand-alone document or as a dedicated paragraph within the clinical trial protocol. within Module 1.7.1 of Module 1.

2.4 Content of a SGBA plus demographics action plan

The SGBA Plus Demographics Action Plan is intended to ensure that clinical trial recruitment strategies appropriately reflect the demographic diversity of the Canadian population affected by the disease or condition under investigation. To support this objective, Sponsors are strongly encouraged to adopt the following structured format:

i. Overview and epidemiology of the disease

ii. Intended clinical trial population

Examples of commonly considered SGBA Plus demographic variables include:

Plus: Other intersecting identity factors such as (this is not an exhaustive list):

iii. Currently known differential effects and sensitivities

Sponsors may provide available evidence that highlights any known similarities or differences in disease manifestation or treatment response across distinct population groups—both globally and within Canada. Specifically:

iv. Barriers to recruitment and proposed mitigation strategies

To support inclusive participation in clinical trials, sponsors are encouraged to identify anticipated barriers to recruitment of underrepresented populations and propose actionable solutions. These may include:

Sponsors are encouraged to present these strategies transparently and to monitor the effectiveness of such measures throughout the trial lifecycle.

Refer to Section 3, for overarching recommendations and guidance on developing inclusive clinical trials and strategies for overcoming common recruitment challenges.

3. Best practices in clinical trials

3.1 Best practices for developing inclusive clinical trials

While not a regulatory requirement, these recommendations are intended to support sponsors in strengthening trial design and promoting equitable participation across diverse populations.

  1. Integrating equity, diversity, and inclusion (EDI) throughout trial design
  1. Engage early and authentically with communities

Appendices

Appendix A – Glossary

Terms used throughout the policy are defined below, although it is not an exhaustive list.Footnote 20 The glossary will be updated as required.

Demographic factors:
Are the statistical characteristics of a population that help describe and analyze groups of people. These factors are commonly used in fields like sociology, marketing, public health, and policy making to understand trends, behaviours and needs. Examples of common demographic factors include age, gender, race and ethnicity, education and more
Disaggregated data:
Refers to information/data that has been broken down into smaller subcategories (that is by gender, race, age, income, geography and more) to reveal patterns or trends that might not be apparent in aggregated data
Diversity:
Consists of the conditions, expressions and experiences of different groups identified by age, culture, ethnicity, education, gender, disability, sexual orientation, migration status, geographic location, language and religious beliefs (and other factors)
Ethnicity:
A broader term than race. The term is used to categorize groups of people according to their cultural expression and identification. Commonalities such as racial, national, tribal, religious, linguistic, or cultural origin may be used to describe someone's ethnicity.
Gender:
Refers to the socially constructed roles, behaviours, expressions and identities of girls, women, boys, men, and gender diverse people. It influences how people perceive themselves and each other, how they act and interact, and the distribution of power and resources in society. Gender has traditionally been conceptualized as a binary (girl/woman and boy/man) yet there is considerable diversity in how individuals and groups understand, experience, and express it.
Health equity:
Refers to the absence of unfair and avoidable or remediable differences in health among population groups defined socially, economically, demographically or geographically
Intersectionality:
An approach to analyzing social relations and structures in a given society which recognizes that every person's identity consists of multiple overlapping factors. The term was first coined in 1989 by scholar and civil rights activist Kimberlé Crenshaw to explain how race interacts with gender and other factors to produce barriers for Black women.
Today, intersectionality is understood more broadly as a framework for understanding how people may experience systemic privilege and oppression based on their intersecting identities, depending on how they are valued by social institutions.
Race:
A social construct and is not grounded in biology: racial categorization schemes were invented by Western scientists to support worldviews that considered some groups of people as superior and some as inferior. This is a concern in the health sciences, because beliefs about race-based biological differences can influence how health care providers perceive their patients and make diagnostic or treatment decisions. However, the racialization of certain groups is a very real social phenomenon, and as such, it is necessary to pay attention to race as an identity factor because it has an impact on how people access and receive care and other federal programs and services.
It is recognized that racial categorizations are not biological, the impacts of racial identity need to be measured and assessed along with other identity factors as a determinant of health.
Sex:
Refers to a set of biological attributes in humans and animals. It is primarily associated with physical and physiological features including chromosomes, gene expression, hormone levels and function, and reproductive/sexual anatomy. Sex can be categorized as male, female, or intersex, as there is variation in the biological attributes that comprise sex and how those attributes are expressed.
Sex and gender based analysis plus (SGBA Plus):
An analytical process used in the Health Portfolio. It is an intersectional approach to assess how factors such as sex, gender, age, race, ethnicity, socioeconomic status, disability, sexual orientation, cultural background, migration status, and geographic location interact and intersect with each other and broader systems of power.
Conducting this analysis helps Health Canada to understand how intersecting identity factors, histories, power relations, distribution of resources and individuals' lived realities contribute to differences in accessing health-related resources and health outcomes. Applying SGBA analysis enables the Health Portfolio to formulate responsive and inclusive health research, policies, services, programs and other initiatives to promote greater health equity.

Note about guidance documents in general

Guidance documents provide assistance to industry and health care providers on how to comply with governing statutes and regulations. They also provide guidance to Health Canada staff on how mandates and objectives should be met fairly, consistently and effectively.

Guidance documents are administrative, not legal, instruments. This means that flexibility can be applied. However, to be acceptable, alternate approaches to the principles and practices described in this document should be supported by adequate justification. They should be discussed in advance with the relevant program area to avoid the possible finding that applicable statutory or regulatory requirements have not been met.

As always, Health Canada reserves the right to request information or material, or define conditions not specifically described in this document, to help Health Canada adequately assess the safety, efficacy or quality of a therapeutic product. Health Canada is committed to ensuring that such requests are justifiable and that decisions are clearly documented.

This document should be read along with the relevant sections of the Food and Drug Regulations and other applicable policy and guidance documents.

This document may be updated in the future to align with any future changes made to the Food and Drugs Act or its regulations.
