Bioexcel Lifesciences & Research LLP supports pivotal and confirmatory medical device clinical investigations, including study design, protocol development, sample-size planning, multicenter site operations, monitoring, EDC, biostatistics and final clinical reporting.
The Study Should Support a Clear Confirmatory Conclusion
Typical pivotal questions include:
- Does the device meet the predefined safety objective?
- Does it meet the performance objective?
- Does it provide the intended clinical benefit?
- Is performance comparable or superior to current alternatives?
- Are event rates within an acceptable benchmark?
- Are outcomes consistent across sites?
- Does the benefit-risk profile remain favorable?
- Is the evidence strong enough for the target regulatory objective?
A pivotal study should minimize ambiguity around the final clinical conclusion.

Reconciled With
Design the Study With the Target Submission in Mind
Before study initiation, define:
- Intended regulatory market
- Intended clinical claim
- Device version
- Primary evidence objective
- Follow-up
- Statistical framework
This reduces the risk of generating technically valid data that do not adequately address the submission question.
Confirmatory Evidence for Higher-Risk Technologies
Pivotal clinical evidence may be particularly important for:
Potential Focus
Some Device Questions Require Years, Not Months
Potential long-term endpoints:
- Device survival
- Structural integrity
- Revision-free survival
- Reintervention-free survival
- Late complications
- Functional outcome
Time-to-event methods may be appropriate.
