Representation for Better Science | Acclinate

Written by Acclinate | February 11, 2025

Key Takeaways and Learnings 

  • Stronger clinical research depends on including a wide range of participants to ensure treatments, including targeted therapies, are safe and effective for all appropriate patient populations.
  • Regulatory agencies and industry leaders are placing greater emphasis on ensuring populations reflect those most affected by the conditions being researched.
  • Limited participation in trials can impact a drug's ability to gain market traction, affecting prescriber decision-making, formulary placement, and insurance coverage.
  • Discover actionable steps for improving representation in clinical research.


When representation is discussed within the context of healthcare, conversations usually go right to how it helps individuals gain access to better treatments. But what's often ignored is just how beneficial it is for research itself. The quality and applicability of medical studies hinge on inclusive clinical trials, ensuring that new treatments are both effective and safe for all appropriate populations — not just a select few.

Despite progress in recognizing the importance of representation in clinical research, gaps remain, potentially leading to less safe and effective treatments, financial losses for pharmaceutical companies, and limited access to innovative medicines, including targeted therapies. This issue is particularly clear in kidney disease research, where Black Americans who are nearly 4x more likely to develop kidney failure than White Americans have been historically underrepresented in studies.

Why Representation Matters in Clinical Research

Before understanding why representation matters in clinical research, it's first essential to identify the underlying factor in successful medical advancements: high-quality data. And how do studies acquire this reliable information? Through assessing a thorough, diverse sample of participants. 

Ultimately, without adequate inclusion of populations from multiple backgrounds, clinical research risks producing treatments that may be less effective — or even harmful — when prescribed to the communities that need them most.   

One of the clearest examples of this issue is in kidney disease research. A genetic mutation affecting the APOL1 gene — more common in Black populations with West or Central African ancestry — significantly influences kidney disease risk. Historically, race-based eGFR (estimated glomerular filtration rate) calculations contributed to disparities in diagnosing and treating Black patients with kidney disease.

Recent initiatives have pushed to remove race-based adjustments, and there's also a focus on using precise genetic and biological factors to diagnose kidney disease. However, without concerted efforts to identify the specific, representative population that would benefit most from APOL1-targeted therapies, studies for APOL1-medicated kidney disease may be underdeveloped and their studies delayed. 

The Need for Inclusive Research 

Additionally, without adequate representation in clinical trials, these therapies may face major setbacks. Notably, lack of inclusion in research doesn't just impact health equity — it can cause obstacles to rolling out new medicine.  

For example, marketing teams are often unable to use images of patients of specific races, ethnicities, and other demographics in promotional materials if participants reflecting these populations were not included in pivotal clinical trials. This oversight could affect not only the perception of the treatment's applicability but also its marketability and accessibility. 

Camille (Pope) Campbell, PharmD, RPh, Acclinate's Sr. Director, Health Equity and a seasoned pharmaceutical leader, has witnessed these challenges firsthand. During her tenure at a major clinical research company, she worked closely with marketing teams that were asked to revise entire campaigns because the necessary representation was missing from a pivotal study. "We had to change all the marketing pieces, all the branding, because we didn't have the data to support the use of the visuals of Black patients in the assets," Dr. Pope recalls. "Beyond marketing, missing representation may impact physicians' confidence in prescribing the drug, as well as the ability to secure favorable formulary placement, which directly affects a drug's accessibility and profitability."  

How Expanding Representation Enhances Scientific and Economic Outcomes 

Beyond ethical considerations, representative clinical trials improve both scientific integrity and business outcomes:  

  • Improved Drug Efficacy Insights — Precision medicine relies on data from a wide spectrum of populations to determine how treatments work across different genetic and environmental factors.
  • Stronger Marketability and Formulary Placement — When representative data is missing, insurance companies and guideline committees may assign treatments to lower formulary tiers, making them harder for doctors to prescribe and affecting drug sales.
  • Reduced Financial Risk for Pharmaceutical Companies — Ineffective or unsafe treatments resulting from non-representative trials can lead to costly post-marketing studies, legal liabilities, and lost revenue opportunities.

Dr. Campbell also emphasizes the business case for inclusive clinical trials. "If a pharmaceutical company's competition has stronger and more representative data, they may use that as a brand differentiator. Formulary committees and insurance providers are increasingly looking at representation when making placement decisions. If a drug isn't positioned well, prescribers may not write for it as often (or must complete additional steps — like prior authorization paperwork — to prescribe it), which may affect sales," she explains.

Bridging the Representation Gap in Research 

To prevent these consequences, the healthcare industry must take proactive steps: 

  • Community Engagement — Historical injustices have fueled mistrust in medical research. Partnering with trusted community leaders and providing clear, transparent information about clinical trials is essential. The people-first platform NOWINCLUDED actively educates communities about their health and raises awareness about care options.
  • Inclusive Study Design — Expanding trial eligibility, diversifying research sites, and offering logistical support (such as transportation and childcare) can break down participation barriers.
  • Regulatory and Industry Commitment — While the FDA has issued guidance on clinical trial representation, the industry must take independent action to ensure meaningful inclusion, regardless of the evolving geopolitical atmosphere.

Final Thoughts: The Future of Representative Research 

Ensuring representation in clinical trials isn't just about equity — it's about advancing science in ways that benefit everyone. The case of APOL1 research highlights how inclusion benefits both patients and companies developing life-saving treatments, including precision medicines. Without a wide array of participants, we risk developing drugs that may not be safe and effective for everyone, increasing healthcare costs, and limiting access to effective treatments — setting back the healthcare ecosystem at large. 

Now, more than ever, industry leaders, researchers, and policymakers must stand firm in their commitment to representation. "This isn't just about making people feel included," says Dr. Campbell. "It's about making sure science works for everyone — and that's something we can't afford to ignore."
