Diversity In Clinical Trials
Clinical research is vital in developing knowledge geared toward improving future health practices. It is often the only feasible solution to medical conditions where standard treatment has failed. Research can be groundbreaking and progressive but study populations lack diversity, especially regarding demographics such as race, ethnicity, age, and sex. Which begs the question: “Why is diversity important to research?” Simply put, various subsets of people can process the same medication differently. Through the clinical research process (guided by strict safety protocols), researchers gather data on how participants experience the same investigational product (IP). Suppose a clinical trial includes people from many different age, gender, and racial/ethnic groups. In that case, researchers will then have data on how several groups of people respond to the same product based on those differences. When these new products reach the market, doctors will know what works best, what doesn’t, and for whom based on those findings. Through research, doctors learned that it is best to prescribe particular medications based on patients’ ethnicity/racial background when treating hypertension. As we move forward, the clinical research community thrives on increasing the participation of all minority age, gender, and racial/ethnic groups to improve the safety profile of medical products. The US government must lead this effort through legislation.
At ENCORE, we recognize that to benefit the communities we serve, we must take the steps necessary to best represent ALL in the trials we conduct. However, this requires overcoming numerous challenges, including long-standing mistrust and economic barriers which prevent minority groups from accessing and participating in research.
Even though clinical trials have evolved from historically unethical practices involving minority racial groups to a transparent process where participant safety and protection are paramount, there is still a significant lack of trust on the part of potential study subjects. Especially for those who are dubious, establishing credibility and integrity within clinical research practice is crucial to growing minority group participation. We believe that physicians, especially those who serve ethnically/racially variant communities, play a significant role in achieving Diversity in clinical trials by bridging trust between researchers and minority participants. ENCORE physicians have dedicated their efforts to working alongside primary care physicians and specialists who serve these communities; to provide them with research material relevant to their practice. Doctors then have the information to make informed recommendations on whether a particular clinical trial is appropriate for their patients. Not only are people more likely to be confident in the recommendations coming from their doctors, but doctors find themselves better prepared to help patients who have failed on current therapeutic approaches.
Unlike when seeking intervention via traditional means, economic hindrance isn’t a preventative factor when one chooses to participate in clinical research. Healthcare costs are a significant burden to many; however, all of the investigational medical products available here at ENCORE cost our patients nothing. All study-related materials, evaluations, blood tests, and imaging are done for free. Study participants will never be billed. Sponsors such as pharmaceutical companies, governments, and foundations fund medical research through study grants. Grants provide the funding to conduct studies at local research sites, so the cost is not transferred to the volunteers. This allows people experiencing financial constraints or without health insurance the opportunity to receive potentially groundbreaking medical treatment at no cost to them. A small monetary compensation is often provided for participants’ time and inconvenience associated with participating in a clinical study. Payment is kept within a reasonable amount to prevent enticement and undue influence on participants.
Despite these steps, we recognize that much more needs to be done to garner diverse research participants in all our trials. Appropriately representing Diversity in clinical trials is an ethical and medical obligation that bounds all stakeholders. Critical players like research sponsors, investigators, referring physicians, coordinators, recruiters, and patients must work collaboratively to achieve this goal. A multi-level stakeholder approach can be more successful than one which addresses a single barrier or involves individual stakeholders. As a research facility, our responsibility in achieving increased Diversity amongst trial participants will build on our investments towards nurturing long-standing relationships. These relationships are between sponsors, community members, our diverse pool of staff and physicians, and our commitment to engagement and learning from diverse patient groups. With this approach, we are confident that trial enrollment will continue to become more diverse and result in a more accurate representation of the people that products are intended to treat.
