Our mission
Helping breakthroughs reach patients faster.
We are former FDA reviewers and decision-makers across CBER, CDER, and CDRH with 100+ years
of combined experience across cell & gene therapy (CGT) including mRNA, AAV, ADC,
immunotherapies for vaccines, oncology, regenerative medicine and tissue engineering for
medical device and combination products.
We started Deffai to help teams understand and anticipate FDA expectations, so lifesaving
medicines and devices can get to market faster.
Work with the team that set the bar.
Put former FDA reviewers — and the AI they built — on your next submission.
