SUMMARY:

The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance for industry entitled “Qualification of Biomarker—Total Kidney Volume in Studies for Treatment of Autosomal Dominant Polycystic Kidney Disease.” This draft guidance provides a qualified context of use (COU) for total kidney volume (TKV), measured at baseline, to be used as a prognostic enrichment biomarker to select patients with autosomal dominant polycystic kidney disease (ADPKD) at high risk for a “progressive decline” in renal function, defined as a confirmed 30 percent decline in the patient's estimated glomerular filtration rate (eGFR), for inclusion in interventional clinical trials. This draft guidance also describes the experimental conditions and constraints for which this biomarker is qualified through the Center for Drug Evaluation and Research (CDER) Biomarker Qualification Program. This biomarker can be used by drug developers for the qualified COU in submissions of investigational new drug applications, new drug applications, and biologics license applications without the relevant CDER review group reconsidering and reconfirming the suitability of the biomarker.

In the Federal Register of January 7, 2014, FDA announced the availability of a final guidance for industry entitled “Qualification Process for Drug Development Tools” that described the process that would be used to qualify Drug Development Tools (DDTs) and to make new DDT qualification recommendations available on FDA's Web site. The qualification recommendations in this draft guidance were developed using the process described in that guidance.

DATES:

Although you can comment on any guidance at any time (see 21 CFR 10.115(g)(5)), to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance, submit either electronic or written comments on the draft guidance by October 16, 2015.

ADDRESSES:

Submit written requests for single copies of the draft guidance to the Division of Drug Information, Center for Drug Evaluation and Research, Food and Drug Administration, 10001 New Hampshire Ave., Hillandale Building, 4th Floor, Silver Spring, MD 20993-0002. Send one self-addressed adhesive label to assist that office in processing your requests. See the SUPPLEMENTARY INFORMATION section for electronic access to the draft guidance document.

Submit electronic comments on the draft guidance to http://www.regulations.gov. Submit written comments to the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.

I. Background

FDA is announcing the availability of a draft guidance for industry entitled “Qualification of Biomarker—Total Kidney Volume in Studies for Treatment of Autosomal Dominant Polycystic Kidney Disease.” This draft guidance provides qualification recommendations for the use of TKV, measured at baseline, as a prognostic enrichment biomarker to select patients with ADPKD at high risk for a “progressive decline” in renal function, defined as a confirmed 30 percent decline in the patient's eGFR, for inclusion in interventional clinical trials. This biomarker may be used in combination with the patient's age and baseline eGFR as an enrichment factor in these interventional clinical trials. Specifically, this draft guidance provides the COU for which this biomarker is qualified through the CDER Biomarker Qualification Program. Qualification of this biomarker for this specific COU represents the conclusion that analytically valid measurements of the biomarker can be relied on to have a specific use and interpretable meaning. This biomarker can be used by drug developers for the qualified COU in submission of investigational new drug applications, new drug applications, and biologics license applications without the relevant CDER review group reconsidering and reconfirming the suitability of the biomarker. “Qualification” means that the use of this biomarker in the specific COU is not limited to a single, specific drug development program. Making the qualification recommendations widely known and available for use by drug developers will contribute to drug innovation, thus supporting public health.

In the Federal Register of January 7, 2014 (79 FR 831), FDA announced the availability of a final guidance for industry entitled “Qualification Process for Drug Development Tools” that described the process that would be used to qualify DDTs and to make new DDT qualification recommendations available on FDA's Web site at http://www.fda.gov/​Drugs/​GuidanceComplianceRegulatoryInformation/​Guidances/​default.htm. The current draft guidance is an attachment to that final guidance.

CDER has initiated this formal qualification process to work with developers of these biomarker DDTs to guide them as they refine and evaluate DDTs for use in the regulatory context. Once qualified, biomarker DDTs will be publicly available for use in any drug development program for the qualified COU. As described in the January 2014 guidance, biomarker DDTs should be developed and reviewed using this process. For more information on FDA's DDTs Qualification Programs, refer to the following Web page: http://www.fda.gov/​Drugs/​DevelopmentApprovalProcess/​DrugDevelopmentToolsQualificationProgram/​default.htm.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the Agency's current thinking on the use of TKV, measured at baseline, as a prognostic enrichment biomarker to select patients with ADPKD at high risk for a progressive decline in renal function, defined as a confirmed 30 percent decline in eGFR, for inclusion in interventional clinical trials. This biomarker may be used in combination with patient age and baseline eGFR, as an enrichment factor in these interventional clinical trials. It does not establish any rights for any person and not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.

II. The Paperwork Reduction Act of 1995

This guidance contains an information collection that is subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The information collection has been approved under the OMB control numbers 0910-0001 and 0910-0014. The information requested in this guidance is currently submitted to FDA to support medical product effectiveness (see 21 CFR 312.30, 21 CFR 314.50(d)(5), and 21 CFR 314.126(b)(6)).Start Printed Page 49246
