What a First-in-Human Study Should Answer

The Objective Is Not to Prove Everything at Once

A first-in-human study may aim to answer:

First-in-human medical device clinical investigation with staged enrollment
  • Can the device be used as intended?
  • Can the procedure be performed safely?
  • Are there unexpected device-related risks?
  • Is device deployment technically feasible?
  • Does the device perform as expected?
  • Are modifications required?
  • What endpoints are practical?
  • What follow-up is needed?
  • What should change before a pivotal study?

The study should remain focused on early learning and controlled risk exposure.
