FDA is announcing the availability of a final guidance for industry entitled “Investigational Enzyme Replacement Therapy Products: Nonclinical Assessment.” The nonclinical study requirements for ERT products may be different from products used to treat other diseases because of the rare, seriously debilitating, and life-threatening nature of the diseases treated by ERT products. Currently, there is no other final guidance that provides recommendations about the substance and scope of nonclinical information needed to support initiation of clinical trials, ongoing clinical development, and marketing approval of ERT products. This guidance provides consistent recommendations for nonclinical studies to expedite developments of ERT products used to treat these rare, life-threatening conditions, especially in pediatric patients.
This guidance finalizes the draft guidance of the same title issued May 13, 2015. All public comments received on the draft guidance have been considered, and the guidance has been revised as appropriate, along with a few editorial changes. Changes from the draft to the final include the following: “Changes in disease-specific biomarkers” has been added as a pharmacodynamic endpoint; a statement on the preference for animal disease models in assessing pharmacodynamic activity has been added; safety pharmacology parameters to proof-of-concept studies were added; a statement was added to clarify the exposure margins; a clarification on the rapidly progressing disease phenotype was provided by adding “approximately” 1 year; a statement on the 3-month toxicology study in one species to support marketing approval was added; and a statement on recovery animals was added.
This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the current thinking of FDA on “Investigational Enzyme Replacement Therapy Products: Nonclinical Assessment.” It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations. This guidance is not subject to Executive Order 12866.
