Ensuring high-quality data from the Human Challenge Model – Regulatory and Clinical considerations & solutions


Viral-challenge studies are used as proof-of-concept trials after initial activity assessments, Phase I human pharmacokinetic, tolerability studies and must comply with specific clinical trial and regulatory conditions. Moreover, the selection, isolation and manufacture of Challenge Agents for use in the Human Challenge Model (Phase 2a/b) must also meet stringent criteria at all stages if the eventual product is to both comply with regulatory advice and provide pertinent data.

What this webinar will cover:

  • Provide an overview of the use of viral-challenge studies in drug development and the regulatory requirements for this type of studies.
  • Discuss the regulatory requirements for challenge viruses.
  • Review Best Practice for the identification of potential challenge strains and the pilot testing required prior to manufacture to ensure high titres of active agent are achieved.
  • Evaluate the value of various agents with the relative merits of each, as documented in commercial clinical trials, laid out for consideration.
