Start Preamble

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The Food and Drug Administration (FDA or Agency) is announcing the availability of a draft guidance for industry entitled “Development of Therapeutic Protein Biosimilars: Comparative Analytical Assessment and Other Quality-Related Considerations.” This draft guidance describes the Agency's recommendations on the design and evaluation of comparative analytical studies intended to support a demonstration that a proposed therapeutic protein product is biosimilar to a reference product licensed under the Public Health Service Act (PHS Act). Additionally, this draft guidance is intended to provide recommendations to sponsors on the scientific and technical information for the chemistry, manufacturing, and controls (CMC) portion of a marketing application for a proposed product submitted under the PHS Act. This draft guidance revises the guidance entitled “Quality Considerations in Demonstrating Biosimilarity of a Therapeutic Protein Product to a Reference Product” that was published on April 30, 2015.

DATES:

Submit either electronic or written comments on the draft guidance by July 22, 2019 to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance.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FDA is announcing the availability of a draft guidance for industry entitled “Development of Therapeutic Protein Biosimilars: Comparative Analytical Assessment and Other Quality-Related Considerations.” This draft guidance describes the Agency's recommendations on the design and evaluation of comparative analytical studies intended to support a demonstration that a proposed therapeutic protein product is biosimilar to a reference product licensed under section 351(a) of the PHS Act (42 U.S.C. 262(a)). Additionally, this draft guidance is intended to provide recommendations to sponsors on of the scientific and technical information for the CMC portion of a marketing application for a proposed product submitted under section 351(k) of the PHS Act. Although the 351(k) pathway applies generally to biological products, this guidance focuses on therapeutic protein products.

The Biologics Price Competition and Innovation Act of 2009 was enacted as part of the Patient Protection and Affordable Care Act (Pub. L. 111-148) on March 23, 2010, and created an abbreviated licensure pathway under section 351(k) of the PHS Act for biological products demonstrated to be biosimilar to, or interchangeable with, a reference product. Under this abbreviated licensure pathway, FDA will license a proposed biological product submitted under section 351(k) of the PHS Act if, among other things, FDA determines that the information submitted in the application is sufficient to show that the biological product is biosimilar to the reference product.

In the Federal Register of February 15, 2012 (77 FR 8884), FDA announced the availability of the draft guidance entitled “Quality Considerations in Demonstrating Biosimilarity to a Reference Protein Product.” FDA received a number of comments on the draft guidance. In response to these comments, FDA provided further clarification on the general principles described through a final guidance entitled “Quality Considerations in Demonstrating Biosimilarity of a Therapeutic Protein Product to a Reference Product,” which was announced in the Federal Register of April 30, 2015 (80 FR 24257).

In the Federal Register of September 22, 2017 (82 FR 44425), FDA announced the availability of the draft guidance entitled “Statistical Approaches to Evaluate Analytical Similarity.” FDA received a number of comments on the draft guidance. Comments submitted to the docket addressed a range of issues that could impact the cost and efficiency of biosimilar development, including the number of reference product lots the draft guidance would have recommended that biosimilar developers sample in their evaluation of high similarity and the statistical methods for this evaluation. After considering the public comments that FDA received, FDA determined it would withdraw the draft guidance to give further consideration to the scientific and regulatory issues involved. FDA announced the withdrawal of the draft Start Printed Page 23571guidance on June 21, 2018, with the intention of issuing future draft guidance on the evaluation of analytical data to support a demonstration that a proposed biosimilar product is highly similar to a reference product.

This draft guidance revises the guidance issued on April 30, 2015. FDA has adjusted the title of this draft guidance to more clearly communicate that this draft guidance includes the Agency's recommendations on the design and evaluation of comparative analytical studies intended to support a demonstration that a proposed therapeutic protein product is biosimilar to a reference product. In addition to editorial and clarifying edits, the draft guidance includes a section that fulfills the Biosimilar User Fee Act II commitment to publish a revised draft or final guidance, describing statistical considerations for the analysis of analytical similarity data intended to support a demonstration of “highly similar” for biosimilar biological products within 18 months after the close of the public comment period for the withdrawn guidance, “Statistical Approaches to Evaluate Analytical Similarity.”

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 “Development of Therapeutic Protein Biosimilars: Comparative Analytical Assessment and Other Quality-Related Considerations.” 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 guidance refers to previously approved collections of information found in FDA regulations, which are not expected to change as a result of the guidance. 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 collections of information related to the submission of: (1) An investigational new drug application, which is covered under 21 CFR part 312 and approved under OMB control number 0910-0014; (2) a new drug application, which is covered under 21 CFR 314.50 and approved under OMB control number 0910-0001; (3) a biologics license application (BLA) under section 351(a) of the PHS Act, which is covered under part 601 (21 CFR part 601) and approved under OMB control number 0910-0338; and (4) a BLA under section 351(k), which is covered under part 601 and approved under OMB control number 0910-0719.
