Clinical Study Design

Biomedical research study

Pepgra is your reliable CRO. Our experts in scientific, clinical, regulatory, and statistical study will design your clinical protocols and execute trials.

Clinical study design and protocols that balance the interests of multiple stakeholders

To estimate the magnitude of treatment effect or difference in the treatment effect, there is a need for a good trial design approach that allows the treatment effect to be sorted out from person-to-person with variation in the responses. With a better-informed protocol, clinical trials can answer the objectives of the study while reducing the bias in estimating treatment effects thereby reducing the overall time, costs and also increase value to stakeholders.

At Pepgra, we are sensitive to the need of balancing scientific, regulatory and logistical concerns to design and plan a successful clinical investigation. Our team has experience in developing study design for both new drugs and medical device despite the risk stratification (or class) of the device. Our experts develop study design based on strong scientific evidence, and our study design experts regularly advise on the necessity, implications, and practicality of clinical study design factors.

Three years ago, we had roped in Pepgra to do the clinical study design; in retrospect, we don’t regret it. They took over right from design and protocols to our submission of IDE to FDA. Their Case Report Form (CRF) was impeccable and so were all their assignments—on par with regulatory standards. If you have to make a choice of a CRO partner, then you can bet on Pepgra.
