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 guidance for industry entitled “General Principles for Evaluating the Abuse Deterrence of Generic Solid Oral Opioid Drug Products.” This guidance is intended to assist a person who plans to develop and submit an abbreviated new drug application (ANDA) to seek approval of a generic version of a solid oral opioid drug product that references an opioid drug product with abuse-deterrent properties described in its labeling. The guidance recommends studies, including comparative in vitro and pharmacokinetic (PK) studies, that a potential ANDA applicant should conduct and submit to FDA to demonstrate that a generic solid oral opioid drug product is no less abuse deterrent than its reference listed drug (RLD) with respect to all potential routes of abuse.

I. Background

FDA is announcing the availability of a guidance for industry entitled “General Principles for Evaluating the Start Printed Page 55618Abuse Deterrence of Generic Solid Oral Opioid Drug Products.” Prescription opioid analgesics are an important component of modern pain management. However, abuse and misuse of these drug products have created a serious and widespread public health problem. Addressing this public health crisis is an FDA priority. One potentially important step toward the goal of creating safer opioid analgesics has been the development of opioid drug products that are formulated to deter abuse. “Abuse-deterrent properties,” as that term is used in the guidance to which this notice applies are those properties shown to meaningfully deter abuse; abuse-deterrent properties do not fully prevent abuse or addiction. FDA considers the development of these products a high public health priority. It is important that less costly generic versions of opioids that reference listed drugs whose labeling describes abuse-deterrent properties are available to ensure access to safe and effective analgesics for patients who need them.

If the summary in section 9.2 of the approved labeling for the RLD indicates that FDA has concluded that the RLD has properties that are expected to (or have been shown through postmarketing studies to) deter abuse, the potential ANDA applicant should evaluate its proposed generic drug to show that it is no less abuse deterrent than the RLD with respect to all of the potential routes of abuse. This will ensure the generic drug is no less abuse-deterrent than the RLD with respect to all potential routes of abuse and minimize the risk of shifting abuse to other, potentially more dangerous routes. This guidance describes FDA's current thinking on the studies that should be conducted by a potential ANDA applicant and submitted to FDA in an ANDA to demonstrate that a generic solid oral opioid drug product is no less abuse deterrent than its RLD with respect to all potential routes of abuse. These studies are in addition to other studies that may be needed to support ANDA approval (e.g., as described in product-specific guidances).

The final guidance, like the draft guidance, focuses on the general principles for developing and evaluating the abuse deterrence of generic solid oral opioid drug products formulated to incorporate physical or chemical barriers, agonist/antagonist combinations, aversive agents, or a combination of two or more of these technologies. FDA will continue to assess the state of science and, as novel technologies develop, will address them by issuing additional guidance, as appropriate.

In the Federal Register of March 25, 2016, FDA announced the availability of the draft guidance for industry “General Principles for Evaluating the Abuse Deterrence of Generic Solid Oral Opioid Drug Products” (81 FR 16186). FDA subsequently announced in the Federal Register of October 6, 2016, and held on October 31-November 1, 2016, a public meeting to discuss scientific and technical issues relating to formulation development and premarket evaluation of opioid drug products with abuse-deterrent properties (81 FR 69532). This final guidance reflects our consideration of comments made in the dockets for the draft guidance (Docket No. FDA-2016-D-0785) and for the public meeting (Docket No. FDA-2016-N-2896) and comments made during the public meeting, and provides the Agency's current thinking with respect to the general principles for evaluating the abuse deterrence of generic solid oral opioid drug products.

Among other changes, the final guidance eliminates the recommendation to use a control to identify discriminatory study conditions for comparing the proposed generic opioid drug product (the test (T) product) and the RLD (reference (R) product). Instead, FDA recommends that a potential ANDA applicant conduct extraction studies to assess the particular vulnerabilities of T and R products to inform the comparison of their abuse deterrence. The final guidance also provides more detailed recommendations regarding the conduct of in vivo studies, specifically comparative PK studies of manipulated T and R products to evaluate the potential for abuse by the oral and nasal routes of administration.

Appendix 1 of the final guidance continues to describe some of the ways in which the T and R products can be physically manipulated and provides recommendations for conducting extraction studies to assess the particular vulnerabilities of the T and R products to inform the comparison of their abuse deterrence. FDA continues to recommend potential ANDA applicants follow a tier-based approach to extractability testing to efficiently compare a T product to its R product and limit the number of tests required for evaluating the abuse deterrence of the T product, but has modified some of the initial recommendations regarding solvents.

Appendix 2 provides recommendations for evaluating abuse by ingestion. In the final guidance, FDA clarifies the circumstances under which a potential applicant should conduct a comparative oral PK study. Appendices 3, 4, and 5 provide modified recommendations for evaluating abuse by injection, insufflation, and smoking, respectively.

The guidance addresses the general principles for evaluating abuse deterrence in generic solid oral opioid drug products. FDA may provide additional testing recommendations in future product-specific guidances. For example, FDA may recommend in a product-specific guidance that a potential ANDA applicant evaluate human abuse potential (for example, evaluate a study subject's willingness to take drug again) if R product contains a known aversive agent. Further, FDA will continue to assess the state of the science and, as novel technologies develop, will address them by issuing revised or additional guidance, as appropriate.

Potential ANDA applicants may pose questions regarding evaluation of abuse deterrence for a generic solid oral opioid drug product through FDA's pre-ANDA program. The goals of the pre-ANDA program are to clarify regulatory expectations for prospective applicants early in the development process, assist applicants in developing more complete submissions, promote a more efficient and effective ANDA review process, and reduce the number of review cycles required to obtain ANDA approval, particularly for complex products. FDA considers abuse-deterrent opioids to be products that fall within the definition of complex product as that term has been defined in the GDUFA Reauthorization Performance Goals and Program Enhancements Fiscal Years 2018-2022, which can be found at https://www.fda.gov/​downloads/​ForIndustry/​UserFees/​GenericDrugUserFees/​UCM525234.pdf. The pre-ANDA program provides for, among other things, submission of controlled correspondence and requests for formal meetings between FDA and applicants on complex generic drug development issues.

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 “General Principles for Evaluating the Abuse Deterrence of Generic Solid Oral Opioid Drug Products.” 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.Start Printed Page 55619
