Real World Evidence has become an increasingly important part of the wider clinical research landscape, helping sponsors understand how treatments perform outside the controlled environment of traditional clinical trials. While randomised controlled trials remain central to demonstrating safety and efficacy, they are often conducted in highly selected patient populations and tightly managed settings that do not always reflect routine clinical practice.
For that reason, many sponsors look beyond conventional trial data when they want a broader understanding of treatment use, outcomes and patient experience. Real World Evidence can help provide that additional context, particularly when the aim is to understand how therapies are used in practice, how outcomes vary across different populations or how longer-term experience compares with what was observed in a formal study.
PHARMExcel supports sponsors with clinically grounded evidence generation where real-world data and observational approaches can add useful context to the wider research programme. Our focus is on helping sponsors approach this work in a way that is methodologically sound, proportionate and aligned with the scientific question being asked.
What is Real World Evidence?
Real World Evidence refers to clinical insight generated from data collected outside traditional randomised controlled trials. That data, often referred to as Real-World Data, may come from sources such as patient registries, routine healthcare records, observational studies and other forms of non-interventional data collection.
The value of Real World Evidence lies in the perspective it can offer. It may help sponsors understand treatment patterns, longer-term outcomes, patient experience and how therapies perform across broader and more varied populations than those typically included in tightly controlled studies.
At the same time, Real World Evidence requires careful interpretation. Routine healthcare data are not collected in the same way as trial data, and not every dataset is appropriate for every question. The strength of an RWE programme depends on the relevance of the data source, the clarity of the research objective and the methodological discipline applied to the study design.
How Real World Evidence fits alongside clinical trials
Real World Evidence does not replace clinical trials. Randomised controlled trials remain the accepted standard for demonstrating safety and efficacy in most development settings. What RWE can offer is additional context, particularly where sponsors want to better understand routine use, longer-term patterns or outcomes in populations that may be less visible within conventional trial designs.
This is particularly relevant in therapeutic areas where patient pathways are complex, long-term follow-up is important or routine practice varies across centres and healthcare systems. In those settings, observational evidence can help support a broader understanding of treatment experience, while still sitting alongside the more structured evidence generated through formal clinical studies.
Why this distinction matters
The value of Real World Evidence is usually greatest when it is used to complement conventional trial data rather than compete with it. Sponsors often get more useful insight when both types of evidence are considered together, with each answering slightly different questions.
Observational research and registry-based evidence
One of the more established ways of generating real-world evidence is through observational and registry-based research. These approaches can be useful where sponsors want to examine outcomes in routine care, understand disease patterns or collect information over longer periods than would normally be feasible within a conventional interventional study.
PHARMExcel can support sponsors with the planning and conduct of clinically grounded observational research where the objectives, data sources and methodology are clearly defined. In this context, the emphasis is on ensuring that the study question is meaningful, the approach is realistic and the resulting evidence is interpreted with appropriate care.
Patient experience and longer-term outcomes
A further strength of real-world evidence is that it can sometimes help bring patient experience into sharper focus. Depending on the design of the study and the data available, it may provide useful insight into treatment burden, persistence, symptom patterns and outcomes over time in routine care settings.
This type of evidence can be valuable when considered alongside conventional trial results, especially where sponsors want a broader view of how therapies are experienced in practice. It may also be helpful in areas where long-term outcomes are important, where routine treatment patterns vary or where conventional trial settings do not capture the full complexity of care.
A careful and methodologically sound approach
Generating meaningful real-world evidence depends on more than access to data. It requires a clear research question, an appropriate study design and a realistic understanding of what the data can and cannot support. Poorly matched data sources or over-interpreted findings can create as many problems as they solve.
PHARMExcel’s role in this area is to support evidence generation in a way that remains clinically grounded and scientifically proportionate. Where real-world evidence is appropriate, our contribution is centred on helping sponsors approach it with the same discipline that good clinical research demands elsewhere.
Practical considerations for sponsors
Before starting any Real World Evidence programme, sponsors should be clear about what they want to understand, whether the available data can answer that question and how the evidence will sit alongside the wider clinical programme. This early discipline usually has a direct effect on the usefulness of the final output.
Why sponsors choose PHARMExcel for evidence-focused clinical support
Sponsors choose PHARMExcel because we combine practical clinical research experience with a quality-driven and study-focused way of working. As a smaller, specialist CRO based in the UK, we offer direct access to experienced senior staff, continuity of team and the flexibility and personal service that larger organisations often struggle to match.
Where real-world evidence is relevant to the wider research programme, our value lies in helping sponsors think clearly about the purpose of the work, the feasibility of the approach and how it should sit alongside broader clinical evidence generation. That makes the service more focused, more credible and more useful than a broad claim to cover every aspect of the RWE landscape.
