2018-14055. Oncology Therapeutic Radiopharmaceuticals: Nonclinical Studies and Labeling Recommendations; Draft Guidance for Industry; Availability

AGENCY:

Food and Drug Administration, HHS.

ACTION:

Notice of availability.

SUMMARY:

The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance for industry entitled “Oncology Therapeutic Radiopharmaceuticals: Nonclinical Studies and Labeling Recommendations.” The purpose of this draft guidance is to assist sponsors in designing appropriate nonclinical studies before initiation of first-in-human (FIH) trials and through product approval. In addition, this draft guidance provides recommendations for product labeling, such as duration of contraception to minimize potential risk to a developing embryo/fetus and recommendations for lactating women to minimize potential risk to a nursing infant. This draft guidance intends to provide recommendations for nonclinical programs in a unique and challenging area of product development, provide a more consistent approach in nonclinical studies and product labeling, and reduce the conduct of nonclinical studies that are not informative for product use.

DATES:

Submit either electronic or written comments on the draft guidance by August 28, 2018 to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance.

ADDRESSES:

You may submit comments on any guidance at any time as follows:

SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a draft guidance for industry entitled “Oncology Therapeutic Radiopharmaceuticals: Nonclinical Studies and Labeling Recommendations.” This draft guidance presents FDA's current thinking on nonclinical studies needed to support FIH studies and for approval for therapeutic radiopharmaceuticals. In this draft guidance, the term therapeutic radiopharmaceutical refers to a pharmaceutical that contains a radionuclide and is used in patients with cancer for the treatment or for palliation of tumor-related symptoms (e.g., pain). This draft guidance discusses the following concepts: (1) Evaluation of toxicities from the ligand; (2) evaluation of radiation toxicities; and (3) information for product labeling as related to reproductive toxicity, genotoxicity, carcinogenicity, contraception, and use in lactating women.

Currently, no FDA or International Council for Harmonisation guidance addresses nonclinical studies supporting FIH trials and approval for radiopharmaceuticals for treatment of cancer. The guidance for industry entitled “Nonclinical Evaluation of Late Radiation Toxicity of Therapeutic Radiopharmaceuticals” (available at https://www.fda.gov/​downloads/​Drugs/​GuidanceComplianceRegulatoryInformation/​Guidances/​UCM079242.pdf) describes nonclinical studies to address late radiation toxicity only. This draft guidance provides further clarification of recommendations made in that guidance for the timing and design of late radiation toxicity studies. This draft guidance intends to bring consistency in nonclinical safety assessment and in product labeling for therapeutic radiopharmaceuticals and to reduce the number of nonclinical studies that are not informative for product use.

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 current thinking of FDA on nonclinical studies and labeling recommendations for oncology therapeutic radiopharmaceuticals. 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.

II. Paperwork Reduction Act of 1995

This draft guidance refers to previously approved collections of information found in FDA regulations. These collections of information are 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 collection of information in 21 CFR 312.23(a)(8) for submitting pharmacological and toxicology information has been approved under OMB control number 0910-0014; the collection of information in 21 CFR 201.56 and 201.57 for preparing human prescription drug labeling has been approved under OMB control number 0910-0572; and the collection of information in the “Content and Format of Labeling for Human Prescription Drug and Biological Products; Requirements for Pregnancy and Lactation Labeling” final rule has been approved under OMB control number 0910-0624.
