The Role of Biomarkers in Enhancing Clinical Trials

Clinical trials are essential for validating the safety and efficacy of a product before it enters the market. Whether the product is a new skincare serum, dietary supplement, or pet health formula, clinical trials provide scientifically backed data that assures consumers and regulators of its claims. But what’s becoming an even greater asset to this process are biomarkers—biological indicators that can significantly improve the precision, predictability, and overall effectiveness of clinical trials.

In this article, we’ll explore what biomarkers are, their critical role in clinical trials for non-pharmaceutical applications, and how they’re helping brands create better products.


What Are Biomarkers?


Biomarkers are measurable indicators of a biological state or condition. They can include a wide range of characteristics, such as blood pressure, hormone levels, gene expression, skin hydration, and even observable traits in animals’ health for pet products. Biomarkers are already widely used in medicine to diagnose diseases, monitor health conditions, and evaluate the impact of treatment. However, they also have exciting applications in clinical trials for consumer products.


In the context of non-pharmaceutical products, biomarkers can be harnessed to:

  • Validate a product’s effects on health and wellness

  • Provide objective, measurable data

  • Support claims related to skin appearance, energy levels, and nutritional benefits


The Advantages of Biomarkers in Clinical Trials


Using biomarkers in clinical trials introduces several significant advantages for consumer product brands, researchers, and consumers alike. Here’s why they’re increasingly becoming a cornerstone of advanced product testing.


Enhanced Accuracy in Measuring Outcomes


One of the key benefits of biomarkers is their ability to produce precise and quantifiable results. Traditional clinical trials often rely on subjective measures, such as user surveys or visual assessments, which can sometimes introduce bias or variability. Biomarkers, however, provide objective data that can substantiate claims with scientific rigor.


For example, in skincare trials, measuring collagen levels in the skin through biomarkers can help objectively verify claims about anti-aging effects. In supplement trials, biomarkers like

blood sugar levels can illustrate the impact of ingredients intended to support metabolism.


Faster and More Efficient Trials


Clinical trials that incorporate biomarkers can sometimes reach conclusions faster than trials relying on subjective endpoints alone. With measurable data provided by biomarkers, researchers can observe changes or improvements in a shorter timeframe. This can lead to shorter trial durations, lower costs, and quicker go-to-market timelines.


For brands looking to stay competitive, this efficiency can be game-changing, allowing for faster responses to market trends and consumer demand without compromising on scientific integrity.


Improved Product Safety and Transparency


Biomarkers can reveal not only the efficacy of a product but also its safety. For instance, in pet health trials, biomarkers such as enzyme levels in the liver can indicate whether a new formula is safe for long-term consumption by pets. By using biomarkers to track these safety indicators, brands can prevent potential adverse effects before the product reaches consumers.


This increased transparency builds consumer trust and ensures that only safe, effective products make it to store shelves, which is vital in today’s informed and health-conscious market.


Clear, Data-Driven Product Claims


For any consumer brand, making product claims that are backed by data is a significant competitive advantage. Biomarkers allow brands to make scientifically substantiated claims, whether it’s about the product’s anti-inflammatory properties, energy-boosting effects, or enhanced hydration. This data-driven approach can improve regulatory compliance and support marketing claims that are more likely to resonate with educated consumers.


How Biomarkers Are Used Across Different Product Categories


In non-pharmaceutical trials, biomarkers are being used in creative ways across diverse product categories. Let’s take a look at a few examples:


1. Skincare and Cosmetics


The skincare industry is heavily influenced by product claims related to anti-aging, hydration, and skin clarity. Biomarkers can provide quantifiable insights into these areas. For example, trials might monitor specific proteins associated with skin elasticity to determine if a product truly improves firmness or reduces wrinkles. Biomarkers such as skin moisture levels or markers of oxidative stress can also validate claims about hydration and antioxidant effects.


2. Nutritional Supplements


For dietary supplements, biomarkers help prove that ingredients actually benefit the body in the way they are advertised. For example, blood biomarkers can show how a vitamin supplement impacts nutrient levels in the bloodstream or how an omega-3 product affects cholesterol levels. This helps brands substantiate health claims on products designed to improve cognitive function, support immunity, or boost metabolism.


3. Pet Health Products


In pet health trials, biomarkers have a significant role in assessing an animal’s physical response to supplements or food formulas. Biomarkers such as cortisol levels in saliva or specific enzymes in the blood can provide valuable data on a product's stress-relief effects or its impact on joint health. This is a rapidly growing area, as pet owners seek the same level of transparency and efficacy from pet products as they do for their own wellness items.


Biomarkers and the Future of Decentralized Trials


The rise of decentralized clinical trials (DCTs), which allow participants to complete parts of the study remotely, is another area where biomarkers are becoming invaluable. Biomarkers can provide critical data points that participants can collect at home, using wearables or simple test kits, allowing trials to be conducted outside of traditional laboratory settings. This flexibility can lower the cost of trials and improve participant diversity and retention, leading to more robust and generalizable findings.


Challenges in Using Biomarkers in Clinical Trials


Despite their advantages, the use of biomarkers in clinical trials comes with challenges. Here are a few key considerations:


  • Standardization: Not all biomarkers have been standardized across industries, which can make comparisons between trials challenging.

  • Regulatory Considerations: While biomarkers can substantiate product claims, regulatory bodies still require that they meet specific standards and undergo rigorous validation processes.

  • Cost: The technology and expertise required to measure some biomarkers can be costly, which may limit their use, especially in smaller trials or those with limited budgets.


However, advancements in technology and a growing understanding of biological indicators are making biomarkers more accessible and affordable for a range of applications.


Embracing Biomarkers for Better Product Validation


Biomarkers are transforming the way clinical trials substantiate product claims, offering brands a path to more precise, reliable, and scientifically backed results. By integrating biomarkers into testing processes, brands can improve product transparency and boost consumer trust. As this technology becomes more accessible, biomarkers will likely become a standard in clinical trials, allowing brands to confidently market safer, more effective products across skincare, wellness, and pet health. Embracing biomarkers isn't just a scientific upgrade—it's a commitment to higher product standards and consumer satisfaction.
