The pharmaceutical industry is undergoing a major conversion, driven by the power of data. Real-world evidence (RWE) is emerging as a critical factor in evaluating drug effectiveness and shaping healthcare decisions. This data, gathered from clinical settings, provides insights into how treatments perform in everyday scenarios, going beyond the controlled environments of clinical trials. By leveraging RWE,pharmaceutical companies can make more informed choices about pricing,market access,and how they deliver their drugs too patients. This shift is notably significant in the fight against diseases such as non-small cell lung cancer (NSCLC).

RWE: Beyond Clinical Trials

RWE encompasses a wide range of data, including patient outcomes, quality of life improvements, and healthcare cost reductions. This allows for a extensive understanding of a drug’s impact. Pharmaceutical companies are using RWE to better understand the challenges that patients face, particularly in specific populations.By analyzing real-world data (RWD),companies can map social determinants of health (SDOH),which include socioeconomic factors,environmental factors,and access to care. This approach is crucial for improving health equity, ensuring that all patients, irrespective of their background, have equal access to effective treatments.

Enhancing Clinical Trials with RWD

Using RWD to inform clinical trial design leads to more successful patient recruitment, and drugs that help a wider range of patients. Analyzing demographic and geographic data helps companies identify the best locations for clinical trials, and build teams that understand the community.

“I think if your not addressing the health equity piece, then you are missing out on part of your mission as a life sciences company,” said Steven Emrick, PurpleLab senior vice president of clinical informatics solutions and HealthNexus, during a recent webinar. “You’ve got to be inclusive, you’ve got to look at the patient populations for whom you’re developing therapies. That’s good for your business, that’s good for your brand to be more inclusive in terms of how you design your clinical trials. Don’t think those two things are mutually exclusive – a public health goal and a revenue goal.”

The Role of RWD in overcoming Challenges

Ben Freiberg, principal Informatics systems lead with Genentech’s GCS Computational Catalysts, highlighted the importance of understanding the demographics of a disease during clinical trial design. “The more we know about the demographics of a disease,what diseases are occurring where,and specifically how those pathologies are realized,what the environmental factors are,socioeconomic factors,genetic factors,then it becomes much easier to plan your clinical trial and has a higher chance of success,” Freiberg shared.

RWD helps to validate the effectiveness of treatments. It allows researchers to assess endpoints like overall survival, time to next treatment, and progression-free survival. Research has shown a connection between real-world endpoints and outcomes observed in randomized clinical trials, validating the use of RWD for informing regulatory and payer decision-making.

Understanding Real-World Data (RWD) & Real-World Evidence (RWE)

Real-World Data (RWD) refers to data relating to patient health that is collected outside of traditional clinical trials. This encompasses a vast range of sources, including:

Electronic Health Records (EHRs): A cornerstone of RWD, providing longitudinal patient data.

Claims Data: Information from insurance claims, detailing diagnoses, procedures, and costs.

Patient-Generated Health Data (PGHD): Data actively shared by patients, often through wearables, mobile apps, and patient registries. Examples include fitness tracker data, symptom diaries, and direct patient reported outcomes (PROs).

Registries: Databases focused on specific diseases or conditions, tracking patient characteristics and treatment patterns.

Public Health Data: Information collected by government agencies, such as immunization records and cancer registries.

Real-world Evidence (RWE) is the insight gained from analyzing RWD. It complements, and in some cases can substitute for, evidence generated from randomized controlled trials (RCTs). The increasing acceptance of RWE by regulatory bodies like the FDA and EMA is driving its adoption in clinical trial design.

The Limitations of Traditional Clinical Trials

While RCTs remain the gold standard for establishing efficacy, they have inherent limitations:

Cost: Traditional trials are incredibly expensive, frequently enough exceeding millions of dollars.

Time: Drug advancement timelines are lengthy, frequently taking 10-15 years from revelation to market.

Recruitment Challenges: Enrolling a representative patient population can be difficult, leading to biased results. Diversity in clinical trials remains a important concern.

Artificial Environments: Highly controlled trial settings may not accurately reflect real-world clinical practice.

Limited Generalizability: Results may not be applicable to all patient subgroups or real-world scenarios.

How RWD is Transforming Clinical Trial Design

RWD is impacting clinical trials across multiple phases, from initial planning to post-market surveillance.
