Regulatory Affairs For Clinical Trials

End to end regulatory affairs services: regulatory operations, submissions and package writing from CTA/IND and beyond.

  • End to end support: regulatory consultancy, operations submissions & agency engagement, and regulatory writing aligned to ICH GCP.
  • Lifecycle coverage: before, during, and after trials — from CTA/IND packs, Investigator Brochures, Investigational Medicinal Product Dossiers, Protocol, to interim safety updates (e.g. DSUR), and clinical study reports (including lay summaries).
  • Integrated within a full service early phase CRO spanning clinical operations, biometry, medical writing, laboratory (BSL 2/3), and specialised human challenge studies.
  • Strategic advantage: early regulatory strategy de-risks programmes, accelerates timelines and unlocks expedited pathways (e.g., FDA Fast Track, EMA PRIME, Orphan Drug designation) which can transform development trajectories.

Regulatory Strategy as Competitive Advantage: From Compliance to Acceleration

For many years, regulatory affairs were viewed as a necessary hurdle in drug development. The role was to ensure compliance, prepare dossiers, and shepherd submissions through complex national and international frameworks. That perception is outdated. Today, regulatory strategy is not simply about compliance; it is a source of competitive advantage. When integrated early into drug development planning, regulatory expertise can accelerate timelines, de‑risk programmes, and even enhance the commercial value of a compound. At hVIVO, our regulatory experts have seen this transformation first‑hand. Their experience across early‑phase clinical trials, human challenge studies, and complex therapeutic areas has shown that regulatory affairs are no longer confined to the back room. They are central to shaping development pathways, influencing policy, and ensuring that innovative treatments reach patients more quickly.
