Antiviral Product Development--Conducting and Submitting Virology Studies to the Agency

FinalCenter for Drug Evaluation and Research06/05/2006

Description

The purpose of this guidance is to assist sponsors in the development of antiviral drugs and biological products (i.e., therapeutic proteins and monoclonal antibodies) from the initial preIND through the new drug application (NDA) and postmarketing stages. This guidance should serve as a starting point for understanding what nonclinical and clinical virology data are important to support the submission of an investigational new drug application (IND), NDA, or biologics license application (BLA) for approval of an antiviral product. This guidance focuses on nonclinical and clinical virology study reports and makes recommendations for collecting and submitting resistance data to the Food and Drug Administration (FDA). Nonclinical and clinical virology study reports, based on collected data, are essential for the FDA’s review of antiviral drug investigational and marketing applications.

Regulatory Context

Attributes

4
genetic threshold

Determines if a product selects for resistance with few or multiple mutations.

phenotypic resistance

acquisition of a single mutation results in a high degree of phenotypic resistance

Inhibitory Quotient

Parameter discussed in antiviral activity analysis; An IQ is the Cmin/serum-adjusted EC50 value.

therapeutic index

Narrow margins may necessitate dose adjustments

Identified Hazards

Hazards

1
mitochondrial function defects

Linked to inhibition of human pol γ, leading to adverse events in humans.
