FDA 483 Response & Compliance Services

Received an FDA Form 483 or Warning Letter?

VTI Life Sciences helps FDA-regulated manufacturers respond to 483 observations, lift warning letters, and resolve consent decrees. Our consultants — including former federal and international regulatory experts — know exactly what investigators expect, because many of them sat on the other side of the table. We can typically have a senior consultant engaged within 24–48 hours.

How VTI helps you respond:

– Formal 483 Response — clear, credible written responses that address each observation point by point
– Warning Letter & Consent Decree Support — corrective action plans and onsite project management that satisfy the FDA and hold up under re-inspection
– Remediation & CAPA Execution — fixing the underlying systems and root causes, not just the symptoms
– Gap Assessments & Mock Audits — find and close exposures before the FDA does

With 25+ years supporting FDA-regulated companies worldwide, VTI helps you respond quickly, completely, and credibly — when the clock is running.
