CONSIDERING A CLINICAL STUDY?
I Think I Need a Clinical Study, but Where Do I Even Begin?
Planning a clinical study can seem overwhelming. What type of study do I need? What clinical evidence do I need to generate? How do I know what the study needs to demonstrate? And how will I ultimately use the results?
Before jumping into a study design, first understand why you need the clinical study and what you need to learn from it. Those decisions shape everything that follows, including the evidence you need, endpoints, patient population, sites, and ultimately how the study is executed.
CONSIDERING A CLINICAL STUDY
A well planned clinical study starts with the clinical strategy. The protocol comes later, once you understand what the study needs to accomplish and the evidence it needs to generate.
Consider Why You Are Conducting the Study
Are you trying to support a regulatory submission, evaluate safety or performance, support a new indication or claim, generate evidence for publication or adoption, or address another development need?
There may be more than one objective, but they need to be clear from the beginning. They provide the foundation for determining what the study needs to demonstrate.
Understand What You Already Have
Review the evidence that already exists. This may include bench or analytical testing, preclinical data, published literature, prior clinical experience, and data from your product or similar products.
The goal is to understand what the existing evidence supports and where meaningful gaps remain. In some cases, you may have more evidence than you realize. In others, an important question may not yet be adequately addressed.
Determine What You Still Need
Perform a gap analysis to determine what is still needed to support safety, performance, effectiveness, the intended patient population, or proposed claims.
This helps define the clinical question and the evidence the study needs to generate. The study should be built around the evidence you need, rather than starting with a study design and trying to make the evidence fit.
Consider the Regulatory and Development Context
The clinical strategy needs to fit within the broader product development strategy. Regulatory pathway, intended use, proposed claims, product risk, stage of development, and prior regulatory interactions can all influence the clinical evidence requirements.
Considering these factors early helps ensure the clinical strategy supports the overall development plan.
Build a Study That Generates the Right Evidence and Can Be Executed
Once the objectives and evidence needs are clear, they can be translated into the study design. This includes the patient population, endpoints, comparator or control, follow up period, sample size, study procedures, and overall structure.
The design also has to work in the real world. Patient availability, recruitment, site capabilities, standard of care, study procedures, follow up requirements, and operational complexity all affect feasibility.
A scientifically strong study that cannot recruit or be consistently executed across sites is not a strong study plan. Study design and feasibility need to be considered together.
Plan for Execution and Data Quality Early
Site selection and training, data collection, monitoring, endpoint assessment, protocol compliance, vendor oversight, and data management all contribute to the quality and interpretability of the results.
These considerations should be addressed while the study is being planned, not after the protocol is finalized. Doing so can identify operational challenges early, reduce variability and missing data, and help ensure the study generates reliable, usable results.
BRINGING IT ALL TOGETHER
Planning a clinical study is more than writing a protocol and finding sites. It starts with understanding why the study is needed, what is already known, and what still needs to be demonstrated.
Those answers inform the strategy. The strategy informs the study design. The design must be feasible, and the study must be executed in a way that protects data quality.
Working through these decisions early can prevent costly changes later and provide a clearer path from the initial clinical question through study execution.
