Diversity, Equity, and Inclusion in Clinical Research
Achieving diversity, equity, and inclusion (DEI) in clinical trials is crucial for producing comprehensive and effective medical research benefitting all communities. DEI ensures clinical research encompasses diverse populations, considering variations in gender, race, ethnicity, socioeconomic status, and more. This helps to generate inclusive data essential for regulatory review and developing treatments effective for everyone.
Importance of DEI in Clinical Trials
Clinical trials are a cornerstone of medical research, contributing to the development of new drugs and treatments. However, historical underrepresentation of marginalized communities has often led to incomplete or biased data. For example, treatments working well for one group may not be effective or could even be harmful to another group due to differences in genetics, lifestyle, or environment. This highlights the need for diverse participation in clinical trials to ensure all populations benefit from medical advancements.
The U.S. Food and Drug Administration (FDA) emphasizes the need for equal representation in clinical trials to generate useful and inclusive data. The agency’s draft guidance calls for Diversity Action Plans to ensure diverse participants are enrolled, which is critical for developing safe and effective drugs and medical devices for everyone.
The National Institute on Minority Health and Health Disparities emphasizes DEI in research goes beyond race and ethnicity, but should also face for the diverse lived experiences of different populations considering factors such as:
- Socioeconomic status
- Age
- Biological status
- Pregnancy status
- Unhealthy behaviors (such as substance use)
- Environmental conditions (such as pollution)
- Underlying medical conditions or comorbidities
Challenges to Achieving DEI in Clinical Research
Achieving DEI in clinical research is not without challenges. Some common barriers to diverse clinical trial enrollment include:
- Mistrust: Historical mistreatment by medical professionals, such as the Tuskegee Syphilis Study and the mishandling of genetic information from the Havasupai Tribe, has led to a deep mistrust of clinical trials among certain communities. Overcoming this requires significant education and outreach to build trust and inform people about the safety and importance of participating in clinical trials.
- Lack of awareness and education: Many potential participants may not understand what clinical trials entail, their purpose, or the protections in place to ensure safety. More educational efforts are needed to demystify important clinical research and encourage participation.
- Environmental barriers: Physical barriers such as distance from research sites, lack of transportation, and time constraints can prevent potential participants from enrolling in clinical trials. To address this, creating research sites within underserved communities or employing decentralized clinical trial models can help improve accessibility and encourage diverse participation.
- Community engagement: Building relationships with communities is crucial for understanding their unique needs and concerns. Engaging community leaders and providing transparency throughout the trial process can help foster trust and encourage participation.
Strategies for Promoting DEI in Clinical Trials
To address these challenges, several strategies can be employed:
- Community outreach and education: Building relationships with community leaders and organizations can help promote understanding and trust. This involves going beyond traditional healthcare settings and engaging in places like community centers, faith-based organizations, and local health fairs.
- Culturally competent communication: Effective communication tailored to different cultural and linguistic groups is essential for encouraging diverse participation. Ensuring clinical trial information is accessible and understandable can help break down enrollment barriers.
- Diverse research staff and investigators: Having a diverse team of researchers and investigators who reflect the communities they serve can help foster trust and increase enrollment from underrepresented groups. Potential participants are more likely to trust and engage with study staff who share similar backgrounds or experiences.
- Decentralized clinical trials: By employing decentralized models, which can include home visits, remote monitoring, or using local healthcare facilities, clinical trials can become more accessible to participants who may face geographic or logistical barriers.
Regulatory and Ethical Considerations
To ensure ethical standards are upheld, regulatory frameworks such as the Belmont Report and the Declaration of Helsinki guide the ethical conduct of clinical research. These guidelines stress the importance of informed consent, respect for persons, and equitable participant selection. Regulatory bodies like institutional review boards (IRBs) are crucial for reviewing and approving research studies, ensuring they meet ethical standards and protect participant rights.
Other guidelines include:
21 CFR 56.111 and 45 CFR 46.111 | Criteria for IRB approval of research including assessing equitable selection of participants. “In making this assessment the IRB should take into account the purposes of the research and the setting in which the research will be conducted.” |
21 CFR 56.107 and 45 CFR 46.107 | Regulations describe the need for diverse IRB membership, “including consideration of race, gender, cultural backgrounds, and sensitivity to such issues as community attitudes.” If the IRB regularly reviews research involving vulnerable populations, the IRB should include in its review one or more people knowledgeable about and experienced in working with such populations. |
21 CFR 50 Subpart B and 45 CFR 46.116 | Based on “respect for persons” from the Belmont report, this regulation outlines general requirements for informed consent, including basic and additional elements of that should be included in an informed consent document. Also advises against exculpatory language and requires minimized possibility of coercion and undue influence. Provides instruction on providing consent materials in a language understandable to the participant. |
Promoting diversity, equity, and inclusion in clinical research is essential for developing safe, effective, and equitable treatments. Overcoming historical mistrust, improving accessibility, and engaging communities are key steps toward achieving this goal. By prioritizing DEI, clinical trials can provide more comprehensive and relevant data designed to benefits all individuals, ensuring the medical advancements of tomorrow are built on a foundation of inclusivity and fairness.
