Background FDA is announcing the availability of a draft guidance for industry entitled ‘‘Limiting the Use of Certain Phthalates as Excipients in CDER–Regulated Products.’’ This draft guidance provides the pharmaceutical industry with CDER’s current thinking on the potential human health risks associated with exposure to DBP and DEHP. In particular, the draft guidance recommends that the pharmaceutical industry avoid the use of these two specific phthalates as excipients in CDER-regulated drug and biologic products, including prescription and nonprescription products. The recommendations in this guidance do not address the use of DBP or DEHP in other types of FDA-regulated products or exposure to DBP or DEHP due to the presence of any of these compounds as an impurity—including as a result of leaching from packaging materials. Phthalate esters (phthalates) are synthetic chemicals with a broad spectrum of uses. Phthalates are found in certain pharmaceutical formulations, primarily as a plasticizer in entericcoatings of solid oral drug products to maintain flexibility, but they also may be used for different functions in other dosage forms. Phthalates also are found in other products for uses such as softeners of plastics, solvents in perfumes, and additives to nail polish, as well as in lubricants and insect repellents. Phthalates have been studied extensively in animals, and DBP and DEHP have been shown to be developmental and reproductive toxicants in laboratory animals. While the data in humans are less clear, epidemiological studies suggest that certain phthalates may affect reproductive and developmental outcomes. Other studies have confirmed the presence of DBP and DEHP in amniotic fluid, breast milk, urine, and serum. Data from the National Health and Nutrition Examination Survey (NHANES) indicate widespread exposure of the general population to phthalates. Humans are exposed to phthalates by multiple routes, including inhalation, ingestion, and to a lesser degree absorption through the skin. Several observational human studies have reported an association between exposure to certain phthalates and adverse developmental and reproductive effects. The ubiquitous presence of phthalates in the PO 00000 Frm 00061 Fmt 4703 Sfmt 4703 environment and the potential consequences of human exposure to phthalates have raised concerns, particularly in vulnerable populations such as pregnant women and infants. Although the currently available human data are limited, the Agency has determined that there is evidence that exposure to DBP and DEHP from pharmaceuticals presents a potential risk of developmental and reproductive toxicity. While it is recognized that drug products may carry inherent risks, DBP and DEHP are used as excipients, and safer alternatives are available. Therefore, the Agency recommends avoiding the use of DBP and DEHP as excipients in CDER-regulated drug and biologic products. These recommendations apply to CDER-regulated drug and biologic products that are under development (i.e., investigational new drugs), nonapplication products (e.g., over the counter monograph products), and both marketed approved products and those currently under review for marketing consideration (i.e., new drug applications, abbreviated new drug applications, and biologics license applications). There are alternatives to DBP and DEHP for use as excipients in CDERregulated products. Manufacturers with products that contain DBP or DEHP should consider alternative excipients and determine if the alternative excipient they plan to use has been used in similar CDER-approved products and at what level. The Inactive Ingredients Database provides information on excipients present in FDA-approved drug products, and this information can be helpful in developing drug products. As manufacturers reformulate their products, the listings for DBP and DEHP will be removed from the Inactive Ingredients Database. 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 limiting the use of certain phthalates as excipients in CDER-regulated products. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statutes and regulations. II.

SUPPLEMENTARY INFORMATION: I. Background On March 23, 2010, President Obama signed into law the Patient Protection and Affordable Care Act (Affordable Care Act) (Pub. L. 111–148). The Affordable Care Act contains the BPCI Act that amends the Public Health Service Act (the PHS Act) and other statutes to create an abbreviated licensure pathway for biological products shown to be biosimilar to, or interchangeable with, a reference product (see sections 7001 through 7003 of the Affordable Care Act). The implementation of an abbreviated licensure pathway for biological products can present challenges given the scientific and technical complexities that may be associated with the larger and often more complex structure of PO 00000 Frm 00062 Fmt 4703 Sfmt 4703 12853 biological products, as well as the processes by which such products are manufactured. Most biological products are produced in a living system such as a microorganism, or plant or animal cells, whereas small molecule drugs are typically manufactured through chemical synthesis. Among other things, section 351(k) of the PHS Act (42 U.S.C. 262(k)), added by the BPCI Act, sets forth the requirements for an application for a proposed biosimilar biological product. Section 351(k) defines biosimilarity to mean ‘‘that the biological product is highly similar to the reference product notwithstanding minor differences in clinically inactive components’’ and that ‘‘there are no clinically meaningful differences between the biological product and the reference product in terms of the safety, purity, and potency of the product.’’ A 351(k) biosimilar application must contain, among other things, information demonstrating that the biological product is biosimilar to a reference product based upon data derived from analytical studies, animal studies and a clinical study or studies, unless FDA determines that an element described here is unnecessary in a 351(k) application. II. Previous Public Hearing on Biosimilar Pathway As part of our commitment to public outreach, FDA held a 2-day public hearing on the ‘‘Approval Pathway for Biosimilar and Interchangeable Biological Products’’ on November 2 and 3, 2010 (75 FR 61497, October 5, 2010) (November 2010 public hearing). The purpose of that public hearing was to seek comments on a number of issues relating to the implementation of the BPCI Act. Over 40 speakers presented at the public hearing. In addition to the presentations, FDA has received more than 60 public comments to the docket, which closed on December 31, 2010. Information on this prior public hearing, including the Federal Register notice, meeting transcripts, and public comments can be found at https:// www.regulations.gov (Docket No. FDA– 2010–N–0477). FDA carefully considered the presentations and public comments as it was developing the recently issued draft guidances (see section III of this document). III. Draft Guidances FDA has issued the following three draft guidances as part of its initial implementation of the BPCI Act based on public input at the November 2010 public hearing regarding priorities for issuing guidances: E:\FR\FM\02MRN1.SGM 02MRN1

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Limiting the Use of Certain Phthalates as Excipients in 
CDER-Regulated Products.'' This draft guidance provides the 
pharmaceutical industry with CDER's current thinking on the potential 
human health risks associated with exposure to DBP and DEHP. In 
particular, the draft guidance recommends that the pharmaceutical 
industry avoid the use of these two specific phthalates as excipients 
in CDER-regulated drug and biologic products, including prescription 
and nonprescription products. The recommendations in this guidance do 
not address the use of DBP or DEHP in other types of FDA-regulated
