For sites and site networks, understanding how RWE is actually being used, and where the opportunities for site involvement exist, is increasingly relevant to business development conversations that go beyond traditional interventional trial recruitment. ## What Counts as Real-World Evidence, and Real-World Data It's worth distinguishing between **real-world data (RWD)**, the raw underlying data sources, and **real-world evidence**, the clinical conclusions derived from analyzing that data. Common RWD sources include: - **Electronic health record data**, aggregated across health systems or research networks, often the richest source for clinical detail but also the most variable in structure and completeness - **Administrative claims data**, from insurers or government payers, which offers excellent longitudinal coverage of a patient's healthcare utilization but limited clinical granularity - **Patient registries**, purpose-built databases tracking specific disease populations over time, often the gold standard for RWE quality because data collection is structured and standardized from the outset - **Patient-generated data**, increasingly including wearable device data and patient-reported outcomes collected outside a traditional clinical encounter RWE is the analysis and interpretation layered on top of these sources, used to answer specific clinical or regulatory questions, such as comparative effectiveness, long-term safety, or treatment patterns in a broader population than a controlled trial would capture. ## How Sponsors Are Using RWE in Trial Design The most direct way RWE is reshaping clinical trial design is through **external control arms**, where real-world data from a comparable untreated or standard-of-care population substitutes for or supplements a traditional randomized control group. This is particularly valuable in rare disease and oncology studies, where randomizing patients to a placebo or inferior standard-of-care arm raises significant ethical and recruitment challenges, and where a well-matched external control arm can materially speed trial completion. Beyond control arms, sponsors are using RWE for: - **Protocol design optimization**, analyzing real-world treatment patterns and patient characteristics to set more realistic inclusion and exclusion criteria before a trial even launches, reducing the risk of an under-enrolling protocol - **Site and country selection**, using real-world disease prevalence and treatment pattern data to identify geographies and site networks most likely to yield strong enrollment for a specific indication - **Endpoint validation**, particularly for novel or patient-reported endpoints, where real-world data can help establish that a proposed endpoint meaningfully correlates with outcomes patients and clinicians actually care about ## Regulatory Acceptance of RWE Continues to Expand Regulatory agencies, including the FDA under its ongoing real-world evidence program, have continued to clarify and expand the circumstances under which RWE can support regulatory decision-making, including label expansions, post-marketing safety commitments, and in select cases, primary approval support for rare diseases or conditions where traditional randomized trials are impractical. This regulatory acceptance has been a key driver behind sponsor investment in RWE infrastructure and data partnerships, since the evidence now has a genuine, growing pathway to translate into label and reimbursement value, not just supplementary publication material. ## Where Site Networks Fit Into the RWE Opportunity For research sites and embedded networks, particularly those built inside a larger health system or care delivery network with substantial EHR data, RWE creates a business development opportunity that runs parallel to, rather than replacing, traditional interventional trial recruitment. Specific opportunities include: - **Registry participation**, where a network contributes structured, longitudinal patient data to a disease-specific registry, often creating an ongoing relationship with a sponsor or academic consortium independent of any single interventional study - **Data partnership agreements**, where a health system's aggregated, de-identified EHR data is licensed or shared under a research collaboration agreement to support a sponsor's RWE analysis, an increasingly common revenue and relationship-building avenue for larger networks - **Hybrid trial designs incorporating RWE**, where a network's existing patient population data supports elements of a trial's external control or run-in period, reducing the burden of prospective data collection during the interventional phase itself ## Comparative Effectiveness Research and the Payer Connection Beyond regulatory applications, real-world evidence has become central to how payers and health technology assessment bodies evaluate a therapy's value once it reaches the market, through **comparative effectiveness research** that examines how a treatment performs against existing standard-of-care options in routine clinical practice rather than in the controlled conditions of a randomized trial. This payer-facing use case has grown in importance as pricing and reimbursement decisions increasingly demand evidence beyond the traditional efficacy and safety data package submitted for regulatory approval. For site networks, this creates an additional, somewhat less obvious business development angle: sponsors conducting comparative effectiveness studies post-approval often need the same kind of well-characterized patient population and reliable data infrastructure as a pre-approval interventional trial, but the study design frequently involves observational data collection rather than an investigational product, which can be a lower-barrier entry point for networks newer to structured research participation. Networks that position themselves as capable partners for this type of post-approval real-world research, in addition to traditional interventional trials, broaden the range of sponsor relationships available to them beyond the interventional trial pipeline alone. ## Data Quality as the Gating Factor The single biggest constraint on a site network's ability to participate meaningfully in RWE initiatives is data quality and structure. Sponsors and RWE-focused researchers consistently report that the biggest barrier to using real-world data isn't availability, it's the effort required to clean, standardize, and validate data that was originally captured for clinical care purposes rather than research purposes. Networks that invest in structured data capture practices, standardized coding, and data governance infrastructure ahead of a specific RWE opportunity are far better positioned to respond quickly when a sponsor or academic partner approaches with a data partnership proposal. ## The Growing Role of Patient Registries as a Business Development Channel Purpose-built **patient registries**, longitudinal databases tracking a specific disease population over time, deserve particular attention as a business development channel distinct from traditional interventional trial recruitment. Registries are typically sponsored by a combination of pharmaceutical companies, academic consortia, and sometimes patient advocacy organizations, and site participation usually involves structured, ongoing data contribution for enrolled patients rather than a single defined study period. For a site network, registry participation offers a few distinct advantages compared to interventional trial work. Registry relationships tend to be longer-duration and more stable than individual interventional studies, providing a more predictable revenue stream once established. They also often serve as a relationship-building foundation with a sponsor that can lead to interventional trial opportunities later, since a sponsor already familiar with a network's data quality and operational reliability through registry participation has a lower-risk pathway to considering that same network for an interventional study. Networks pursuing registry opportunities should approach the business development process similarly to interventional trial pursuit: identifying relevant registry sponsors and academic consortia active in the network's core therapeutic areas, and building the same kind of systematic, documented outreach cadence used for traditional sponsor relationships. ## Preparing to Engage in RWE Partnerships: A Readiness Checklist Networks interested in pursuing real-world evidence partnerships benefit from building foundational readiness before actively pursuing a specific opportunity: - Conduct a data quality audit across core EHR fields relevant to the network's priority therapeutic areas, identifying gaps in structured versus free-text data capture - Establish a data governance policy covering de-identification standards, data use agreement templates, and internal approval processes for external data sharing - Identify and document the network's population strengths, such as specific disease prevalence or demographic characteristics that would make the network an attractive RWE partner - Build relationships with academic epidemiology or biostatistics contacts who may serve as either direct research partners or referral sources to sponsor RWE teams - Start with a smaller, well-defined registry or data partnership opportunity to build a track record before pursuing larger, more complex RWE collaborations ## Frequently Asked Questions on Real-World Evidence **Does RWE participation require a site to have a formal IRB and research infrastructure in place?** Generally yes, particularly for registry participation or interventional hybrid designs, though the level of research infrastructure required is often lower than for a traditional interventional trial, since aggregated data partnerships frequently rely on de-identified data governed under a separate data use agreement rather than a full clinical protocol. **How is RWE different from simply being a site with a large patient database?** Having a large patient population is a starting point, but real-world evidence generation requires the data to be structured, validated, and analytically usable in a way that supports defensible clinical conclusions, which is a meaningfully higher bar than simply having a large EHR system. **Is RWE work a realistic near-term revenue opportunity for a mid-size site network, or mainly relevant to large academic systems?** Increasingly realistic for mid-size networks, particularly those with a well-characterized population in a high-demand therapeutic area, though building the data infrastructure and initial sponsor or academic relationships typically takes longer to establish than a traditional interventional trial relationship. ## Conclusion Real-world evidence has become a core input into how modern clinical development programs are designed, executed, and supported through regulatory review, not a supplementary afterthought generated after a drug reaches the market. For site networks with strong underlying patient population data, this shift represents a genuine business development opportunity that runs alongside traditional trial recruitment, but capturing that opportunity depends heavily on data infrastructure and governance investment made well before a specific RWE partnership opportunity arrives.
