Start Supplemental Information
In December 2016, the Cures Act (Pub. L. 114-255) was signed into law. Section 3038(c) of the Cures Act mandated that FDA publish in the Federal Register a list identifying types of combination products and manufacturing processes for which “good manufacturing processes” may be adopted that vary from the requirements set forth in § 4.4 (21 CFR 4.4) or that FDA proposes can satisfy the requirements in § 4.4 through “alternative or streamlined mechanisms,” and to review this list periodically. In accordance with this statutory mandate, FDA is publishing a proposed list in section II of this document, which addresses processes for single-entity and co-packaged combination products that can satisfy requirements in § 4.4 through alternative or streamlined mechanisms (hereafter “mechanisms”).
On January 22, 2013, FDA issued a final rule on CGMP requirements for combination products (see 78 FR 4307 and part 4 (21 CFR part 4, subpart A)). Prior to issuance of the final rule, although CGMP regulations were in place to establish requirements for drugs, devices, biological products, and human cells, tissues, or cellular or tissue-based products (HCT/Ps), there were no regulations to clarify and explain the application of these CGMP requirements to combination products. The final rule clarified which CGMP requirements apply to combination products. It also established a transparent and streamlined regulatory framework for combination product manufacturers to use when demonstrating compliance with applicable CGMP requirements.
A combination product is a product composed of two or more different types of medical products (i.e., a combination of a drug, device, and/or biological product). The drugs, devices, and biological products included in combination products are referred to as “constituent parts” of the combination product. Combination products include “single-entity” combination products that are physically, chemically, or otherwise combined or mixed and produced as a single entity (§ 3.2(e)(1) (21 CFR 3.2(e)(1)) (e.g., prefilled syringes and drug-eluting stents) and “co-packaged” combination products where two or more separate products are packaged together in a single package or as a unit and composed of drug and device products, device and biological products, or biological and drug products (§ 3.2(e)(2)) (e.g., a surgical or first-aid kit).
Section 4.4 outlines how manufacturers of single-entity and co-packaged combination products (hereafter “CP manufacturers”) can demonstrate compliance with applicable CGMP requirements, including through implementation of a streamlined approach to meet the requirements of both the drug CGMP and the device Quality System (QS) regulation by designing and implementing a CGMP operating system that demonstrates compliance with either of the following:
- The drug CGMP regulations in parts 210 and 211 (21 CFR parts 210 and 211) and the following specified provisions from the device QS regulation (§ 4.4(b)(1), “drug CGMP-based streamlined approach”): (1) § 820.20 (21 CFR 820.20) Management responsibility, (2) § 820.30 (21 CFR 820.30) Design controls, (3) § 820.50 (21 CFR 820.50) Purchasing controls, (4) § 820.100 (21 CFR 820.100) Corrective and preventive action, (5) § 820.170 (21 CFR 820.170) Installation, and (6) § 820.200 (21 CFR 820.200) Servicing; or
- The device QS regulation in part 820 (21 CFR part 820) and the following specified provisions from the drug CGMP regulations (§ 4.4(b)(2), “device QS regulation-based streamlined approach”): (1) § 211.84 (21 CFR 211.84) Testing and approval or rejection of components, drug product containers, and closures; (2) § 211.103 (21 CFR 211.103) Calculation of yield; (3) § 211.132 (21 CFR 211.132) Tamper-evident packaging requirements for Start Printed Page 27611over-the-counter (OTC) human drug products; (4) § 211.137 (21 CFR 211.137) Expiration dating; (5) § 211.165 (21 CFR 211.165) Testing and release for distribution; (6) § 211.166 (21 CFR 211.166) Stability testing; (7) § 211.167 (21 CFR 211.167) Special testing requirements; and (8) § 211.170 (21 CFR 211.170) Reserve samples.
If the combination product includes a biological product constituent part, the CGMP operating system must also demonstrate compliance with applicable CGMP requirements for biological products in parts 600 through 680 (21 CFR parts 600 through 680), and if the combination product includes an HCT/P, the CGMP operating system must also demonstrate compliance with the applicable current good tissue practice requirements in part 1271 (21 CFR part 1271).
Following publication of the final rule, FDA reviewed data and rationales provided by manufacturers who proposed various means of addressing CGMP considerations for combination products. FDA also considered feedback on its draft guidance on CGMP requirements for combination products, published in January 2015, in which stakeholders requested further guidance on circumstances in which flexible approaches may be available and how to engage with FDA on them. The final “Guidance for Industry and FDA Staff: Current Good Manufacturing Practice Requirements for Combination Products” includes discussion of existing mechanisms to comply with the final rule and of circumstances in which FDA did not intend to object to manufacturers applying practices that vary from the requirements set forth in the rule (Ref. 1). The Agency continues to apply a risk-based approach to evaluating methods for ensuring the quality of combination products and to welcome proposals from manufacturers for how to enhance the efficiency of development and manufacturing activities, while ensuring the safety and effectiveness of the combination products produced.
II. Proposed List of Mechanisms for Complying With § 4.4 CGMP Requirements for Combination Products
The following is a proposed list of mechanisms for demonstrating compliance with relevant combination product CGMP requirements, as described below. Where applicable, reference is made to sections of the “Guidance for Industry and FDA Staff: Current Good Manufacturing Practice Requirements for Combination Products” for additional information (Ref. 1). FDA will continue to evaluate this list in light of Agency experience and stakeholder input. Manufacturers are welcome to propose other approaches not described, and FDA continues to encourage dialogue with the Agency on various means of demonstrating CGMP compliance for combination products.
For each mechanism described below, CP manufacturers should consider what documentation would be sufficient to support that the mechanism, including the specific approach for implementing it, assures appropriate control of the manufacture of the combination product to ensure safety and effectiveness of the product. Appropriate evidence and an explanation of the rationale to support the approach should be accessible at the manufacturing facility for review during facility inspections. For additional discussion on how to interact with FDA regarding the mechanisms described below, see section III.
B. Mechanisms for Complying With Drug CGMP Requirements (Part 211) Specified in § 4.4 
FDA interprets the mechanisms identified in the sections below as a means to demonstrate compliance with the specified part 211 requirements identified in § 4.4:
1. Section 211.165 Testing and Release for Distribution
Use of product samples that are not finished combination products (but that are representative of the finished combination product with respect to the characteristics and attributes being tested) when performing testing required by § 211.165 to determine whether the drug constituent part meets final specifications. To meet the requirements of § 211.165, the CP manufacturer would need to establish, including where appropriate through bridging studies and other quantitative means, that any differences in the manufacturing process for the representative samples as compared to the finished combination product do not affect the drug constituent part. For example, as part of product release testing, drug-eluting lead manufacturers could perform release testing for identity, potency, or other quality attributes on a representative lead tip assembly that contains the drug constituent part, but does not contain the full electronic and mechanical assembly, so long as they can establish that the differences in the manufacturing process do not impact the drug constituent part and the sample is representative of the finished combination product with respect to the quality attributes being tested.
(See also Section IV.B.5 of Reference 1 for additional information on testing and release for combination products.)
2. Section 211.166 Stability Testing
Use of bracketing and matrixing approaches to stability studies for combination products. Principles for bracketing and matrixing approaches to meet the requirements of § 211.166 have already been addressed by the Agency with regard to drug products (Ref. 2), and such principles can also be applied to combination products. For example, when assessing stability for a prefilled syringe that is marketed in various fill volumes, one of the approaches that a CP manufacturer could utilize, if appropriate, is bracketing based on the smallest and the largest fill volume of product configurations. In determining the extremes for a bracketing approach and/or when justifying the use of a matrix design for single-entity combination products, it is important that the drug-device interactions and variations in the manufacturing processes are considered. For co-packaged combination products, such approaches can be applied to the drug constituent part of the product.
Leveraging stability data for an already marketed combination product. Such mechanisms can be considered when the new combination product is a modification of an already marketed product and the modification does not impact the stability of the drug constituent part. For example, when developing new lengths of a drug-coated catheter product for which the catheter materials, drug coating, manufacturing process, and packaging configurations are largely unchanged from existing marketed sizes, the CP manufacturer would generally be able to leverage existing stability data to establish initial product shelf life or to support reduced stability data requirements, so long as characteristics of the product that could impact stability (materials, packaging configuration, etc.) remain the same. However, if the device constituent part of a drug-coated catheter includes a new material that is in contact with the drug coating, for example, new stability studies would generally be needed under § 211.166.Start Printed Page 27612
(See also Section IV.B.6 of Reference 1 for additional information on stability requirements for combination products.)
3. Section 211.167 Special Testing Requirements
Defining “batch” based on the drug constituent part rather than the finished combination product for purposes of special testing requirements for pyrogens and endotoxins. For example, a manufacturer of a combination product that has a sub-assembly coated with a drug, which is then incorporated into several “batches” or “lots” of the overall combination product, may be able to define a batch for purposes of pyrogen and endotoxin testing as a batch of that sub-assembly for purposes of meeting the requirements of § 211.167. As with the other mechanisms described in this list, this mechanism would only potentially be available if there would be no impact on the drug constituent part from subsequent manufacturing processes, including when the constituent parts are combined to produce the final combination product. CP manufacturers should consider whether such risks may be introduced later in the production process (after the batch has been defined). This approach will most frequently apply for co-packaged combination products or single-entity combination products for which only a component or sub-assembly of the overall product is in contact with the drug constituent part.
(See also Section IV.B.7 of Reference 1 for additional information on special testing requirements for combination products.)
4. Section 211.170 Reserve Samples
Keeping reserve samples that are representative of the finished combination product. CP manufacturers may use validated surrogates as representative samples to meet the requirements of § 211.170, provided the surrogate is appropriate, both in terms of the manufacturing process and the characteristics of the container closure. For example, maintaining only a sub-assembly of a coated single-entity combination product or only the drug constituent part of a co-packaged combination product as a reserve sample would generally be permissible under the regulation when: (1) All manufacturing process steps after the coating step or the fill for the drug constituent part are shown not to affect the drug constituent part, (2) the immediate container closure has essentially the same characteristics as that for the drug constituent part as packaged in the combination product for distribution, and (3) the representative samples are suitable for all required testing of the drug constituent part for which the reserve samples are being kept.
Using samples from representative lots of a larger batch for retention of reserve samples. To meet the requirements of § 211.170, CP manufacturers may be able to use bracketing and matrixing approaches to retain reserve samples from certain lots to adequately represent the broadly defined batch of the combination product. For example, CP manufacturers might be able to retain reserve samples of appropriately varied sizes of a drug-coated combination product from within a broadly defined batch that includes multiple lots of different sizes.
(See also Section IV.B.8 of Reference 1 for additional information on reserve sample requirements for combination products.)
C. Mechanisms for Complying With Device Quality System Requirements (Part 820) Specified in § 4.4
FDA interprets the mechanisms identified in the sections below as a means to demonstrate compliance with the specified part 820 requirements identified in § 4.4:
1. Section 820.30 Design Controls
Using existing pharmaceutical development practices and documentation that align with the design control principles and requirements of § 820.30. Robust pharmaceutical development practices would address many design control requirements to assure compliance with § 820.30, where applicable. CP manufacturers need to demonstrate how development processes and terminology align with design control principles and requirements in § 820.30, when required, including, where necessary, developing additional design control elements. When evaluating the adequacy of existing pharmaceutical development processes, particular attention should be given to postmarket management of design changes to the combination product and the alignment of change control practices with the principles and requirements of § 820.30, as applicable.
2. Exemption of Combination Products From Device QS Regulation
Exemption of the combination product from all or certain provisions of the device QS regulation (part 820) if the device constituent part of the combination product is itself exempt from such requirements and use of the device constituent part falls within the scope of the relevant exemption, including with respect to the device constituent part's intended use. Some devices are exempt from all or certain provisions of the device QS regulation (see, for example, liquid medication dispensers such as cups and droppers that fall within the scope of § 880.6430 (21 CFR 880.6430), provided the use of the device is not a new intended use or does not otherwise raise different safety and effectiveness questions (see, for example, limitations to the exemption under 21 CFR 880.9). Consistent with this, for the combination product to be exempt from the associated provisions of the device QS regulation, we interpret this exemption to mean that the use of the device in the combination product must not be a new intended use or otherwise raise different safety and effectiveness questions for the device. This circumstance will most frequently apply to co-packaged combination products. For example, an oral dosing syringe (a liquid medication dispenser under § 880.6430) that is co-packaged with a drug may be exempt from certain provisions of the device QS regulation (and hence the combination product may also be exempt from such provisions); however, incorporation of such a dispenser into a primary container closure system or co-packaging of such a dispenser with an emergency-use product, for example, may constitute a new intended use for the dispenser or raise different safety and effectiveness questions for the dispenser, such that the relevant exemption would not apply.
(See also Section III.C.3 of Reference 1 for additional information on the exemption from provisions of the device QS regulation for combination products.)
III. Interacting With FDA on Mechanisms for Complying With CGMP for Combination Products
1. Process for Interacting With FDA
In some cases, CP manufacturers may interact with FDA to gain approval or otherwise notify FDA of a manufacturing change. In other cases, although a submission or notification is not required, CP manufacturers may want to discuss potential use of CGMP mechanisms with FDA. CP manufacturers are encouraged to interact early with FDA on contemplated CGMP mechanisms.
Pre-Submissions and Meeting Requests. CP manufacturers who want to obtain FDA feedback prior to submitting a premarket application or a postmarket supplement or who otherwise want to obtain feedback on Start Printed Page 27613their approach may interact with FDA via the existing established process applicable to the lead Center 
for the combination product. For combination products reviewed under a new drug application (NDA) or a biologics license application (BLA), such interactions will generally be through Type C meetings (Ref. 3).
For combination products reviewed under an abbreviated new drug application (ANDA), these interactions will generally be through pre-ANDA meetings (Ref. 4).
For combination products reviewed under a device premarket submission (e.g., a premarket approval application (PMA), de novo classification, or premarket notification (510(k)), these interactions will generally be via the pre-submission process (Ref. 5).
Regardless of the type of submission, such interactions should be focused on a general discussion of the mechanism and CGMP approach the CP manufacturer wishes to pursue and associated justification to support the approach. Only representative data is typically appropriate in these interactions; complete data should be included in the subsequent premarket submission or postmarket supplement, if required, and/or be maintained at the manufacturing facility, as appropriate.
Premarket Review. CP manufacturers should include in their original submission for NDAs, BLAs, ANDAs, and PMAs information on any mechanisms for complying with CGMP requirements. For PMAs, this information should be included in the manufacturing section of the PMA. For information regarding where to place information in NDAs, BLAs, or ANDAs, refer to “eCTD Technical Conformance Guide” (Ref. 6).
Postmarket Supplements or Notifications to FDA. Postmarket changes to implement a combination product CGMP mechanism for NDAs, ANDAs, BLAs, and PMAs, may require submission of a supplement or notification to FDA.
CP manufacturers should consult related guidances relevant to the type of constituent part of the combination product (Refs. 7 to 9).
If a CP manufacturer has questions on the appropriate submission type or the need for a submission, they can contact the lead Center for assistance.
2. Content Suggestions
When submitting information on a CGMP mechanism, along with any submission requirements applicable to the submission type, the following content should be included:
Applicable CGMP regulation. Identify the CGMP regulation applicable to the described mechanism. For example, if a submission includes a mechanism related to stability testing, indicate that § 211.166 is the applicable CGMP requirement.
Applicable Products. If the mechanism is to be applied to multiple products and/or product configurations, list all related sizes, strengths, etc., as well as all related application numbers.
Related Interactions with FDA. If the CP manufacturer has had previous interactions with FDA relevant to the proposed mechanism, either for the product addressed in the submission or for related products, the CP manufacturer should provide reference to those interactions. Where applicable, the CP manufacturer may cross-reference previously submitted information.
Justification and Scientific Data. Include a rationale to support that the proposed mechanism assures adequate manufacturing control to ensure product safety and effectiveness. When describing a CGMP mechanism in a premarket or postmarket submission, the description should be accompanied by data necessary to support the approach. When proposing a change from a CGMP approach that was reviewed previously by FDA, such justification should include analysis of how the proposed approach compares to the previously reviewed approach as an effective manufacturing control, including representative data, as appropriate, to substantiate the analysis.
3. FDA Engagement
CP manufacturers are encouraged to discuss combination product CGMP mechanisms with FDA. Any questions on how to engage FDA in such discussions should be directed to the lead Center for the product or the Office of Combination Products, as needed.
4. FDA Review
FDA may review information from a CP manufacturer related to a mechanism for complying with CGMP requirements for combination products in premarket applications, postmarket supplements or notifications, pre-submissions and meetings, and during facility inspections. FDA may determine that the data and rationale presented by a CP manufacturer for a particular mechanism are insufficient to demonstrate that the mechanism, as proposed or implemented, meets the applicable CGMP requirement. FDA generally will notify the CP manufacturer and/or applicant in writing of any such determination.
IV. Other Issues for Consideration
We have developed this proposed list of mechanisms based on information submitted to FDA by CP manufacturers as well as FDA experience with manufacturing processes and CGMP compliance approaches that have been shown through appropriate data and rationales to support the manufacture of safe and effective products. FDA requests comment from stakeholders who believe there are additional types of combination products and/or manufacturing processes where different approaches may be appropriate. When providing such feedback, the suggested approach should be:
- Applicable to a type or range of combination products (e.g., not just a single CP manufacturer's product). Commenters should indicate to which types of combination products or manufacturing processes they believe the suggested approach should apply.
- Supported by adequate data and rationales to demonstrate that such an approach would continue to support manufacturing of safe and effective combination products. Commenters should summarize the data and rationale that support the suggested approach.
Any confidential information submitted to FDA via the docket should be appropriately identified (see Instructions above, in ADDRESSES).
