Combination Products General Overview of 21 CFR Part 4 Requirements Mary C Getz, PhD VP, Quality – NSF Medical Device Consulting

Background Office of Combination Products (OCP) established December 24, 2002 In the Federal Register of October 4, 2004 FDA announced Draft Guidance – “Current Good Manufacturing Practices for Combination Products” –The Agency received 15 comments, which were largely supportive –A common theme – combination products are made up of drug, device, and biological product constituent parts –FDA determined that rulemaking was warranted The Agency published a proposed rule in the Federal Register of September 23, 2009 Final rule became effective July 22,

The Final Rule Established minimum requirements to assure the safety, identity, strength, quality, and purity, as applicable, of drugs, devices, biological products, and HCT/Ps The new regulation does not introduce any new regulations, it just clarifies how existing regulations are expected to be implemented No products are grandfathered – all combination products, regardless of introduction date, are expected to be compliant with the regulations CONFIDENTIAL4

21 CFR 3.2(e) Combination Product Definition Types of Combination products are defined as follows: (1) Single Entity: A product comprised of two or more regulated components, i.e., drug/device, biologic/device, drug/biologic, or drug/device/biologic, that are physically, chemically, or otherwise combined or mixed and produced as a single entity Examples of single-entity products –Prefilled syringe –Transdermal patch –Drug-eluting stents NOTE: a drug packaged as part of container/closure, such as a vial, would not be considered a combo product 5

21 CFR 3.2(e) Combination Product Definition (continued) Types of Combination products are defined as follows: (2) Co-packaged: Two or more separate products packaged together in a single package or as a unit and comprised of drug and device products, device and biological products, or biological and drug products Examples of Co-packaged products –Drug with delivery mechanism i.e., nebulizer, inhaler, dropper or syringe –Convenience kits (first aid kits or surgery kits) 6

21 CFR 3.2(e) Combination Product Definition (continued) Types of Combination products are defined as follows: (3) Cross-labeled: A drug, device, or biological product packaged separately that according to its investigational plan or proposed labeling is –intended for use only with an approved individually specified drug, device, or biological product where both are required to achieve the intended use, indication, or effect and –where upon approval of the proposed product the labeling of the approved product would need to be changed, e.g., to reflect a change in intended use, dosage form, strength, route of administration, or significant change in dose Examples of Cross-labeled products –Light-emitting devices which specify a certain antibiotic or protein solutions to be used in a medical procedure –Drug with specific applications for delivery mechanism 7

So how does the final ruling impact each type of combination product relative to GMPs compliance strategy? 8

Constituent Parts Establish the GMP Regulations The constituent parts* of a combination product retain their regulatory status (as a drug or device, for example) after they are combined Allow the Primary Mode of Action (PMOA) to influence the direction and strategy –In particular, compliance with either the cGMP regulations for drugs 21 CFR 210 and 211 or the quality system (QS) regulation for devices 21 CFR 820 will satisfy many, though not all, of the cGMP requirements applicable to both drug and device constituent parts –However, the PMOA does not dictate the Compliance strategy, the company does 9

Driver of cGMP Constituent Part(s)* establish GMP Regulations –The constituent parts of a combination product retain their regulatory status (as a drug or device, for example) after they are combined –Accordingly, the cGMP requirements that apply to each of the constituent parts continue to apply when they are combined to make combination products *Definition: Constituent part is a drug, device, or biological product that is part of a combination product 10

cGMP Requirements to Meet Combo Products Regs 21 CFR 4.4(e) …In the event of a conflict between cGMP requirements applicable to a combination product, the regulations most specifically applicable to the constituent part at issue shall prevail… –“constituent part at issue shall prevail” Translation: Given what the constituent part in question is, the regulations for that part shall be applied as a priority Example – If the needle component (constituent part is a device) is being evaluated in response to complaints and it was determined that unknown mold cavity changes were made at the vendor, while 21 CFR 210, 211 does not have specific Purchase Controls regarding notification of changes, since the constituent part is a device, 21 CFR (b) would apply requiring the supplier to notify prior to making any changes, as well as (f) to assure verification of those changes 11

cGMP Compliance Options The final rule offers several approaches to selecting the cGMP operating requirements applicable to a co-packaged or single-entity combination product. These options are: (1) Non-streamlined approach – demonstrate compliance with the specifics of both cGMP regulations applicable to each of the constituent parts included in the combination product (2)(a) Demonstrate compliance using the streamline approached based on the CFR 210/211 drug cGMPs (2)(b) Demonstrate compliance using the streamlined approached based on the CFR 820 QS regulation 12

How Industry Can Apply the Regulation 13 The drug constituent must follow applicable sections of the cGMP’s [Parts 210 and 211] The drug constituent must follow applicable sections of the cGMP’s [Parts 210 and 211] The device constituent must follow applicable sections of the QSR’s [Part 820] The device constituent must follow applicable sections of the QSR’s [Part 820] The biologic constituent must follow applicable sections of the cGMP’s [Parts ] The biologic constituent must follow applicable sections of the cGMP’s [Parts ] Drug / Device Combination Product Drug / Device Combination Product Biologic / Device Combination Product Biologic / Device Combination Product

cGMP Requirements to Meet Combo Products Regs 21 CFR 4.4(b)(1) and 21 CFR 4.4(b)(2) If the Operating Manufacturing Control System is Part 820 (QS Regulation) If the Operating Manufacturing Control System is Part 210/211 (CGMP Regulation) CGMP RequirementsTitle Carefully Consider These Specific QS Requirements Title § Testing and approval or rejection of components, drug product containers, and closures § Management responsibilities § Calculation of yield§ Design controls § Tamper-evident packaging requirements for over-the- counter (OTC) human drug products § Purchasing controls § Expiration dating§ Corrective and preventative actions Testing and release for distribution § Installation § Stability testing § Servicing § Special testing requirements § Reserve samples 14

Overview of Regulatory Strategy Considerations for Combo Product Primary Mode of Action (PMOA) –“Most important therapeutic action of a combination product” –Determines Center for product’s review OCP does not review submissions OCP’s purpose is to provide expertise/guidance to sponsors and the Agency, and facilitate timely reviews and consistency in the application of policies –Sometimes PMOA is not clear FDA will look to past precedent, primary safety concerns, and Agency expertise CONFIDENTIAL15

Overview of Regulatory Strategy Considerations for Combo Product PMOA / Product Jurisdiction Determination –Legally determines assignment –Request for Designation (RFD) 15 page limited document with rationale for Sponsor’s suggested PMOA / classification FDA’s formal response within 60 days (binding decision). If deadline is missed, then the requestor’s recommendation applies –Indication for use (overall therapeutic effect) and primary mode of action are critical elements in jurisdictional determination CONFIDENTIAL16

Considerations for Combination Products Evaluate products to determine if the final product meets the definition of a “combination product” to establish the appropriate quality system for the product. This determination shall be documented Product must meet the combination product requirements from “cradle-to-grave” or design development (prior to use in humans) to discontinuation –NOTE: The product must comply with regulatory requirements in the market(s) registered CONFIDENTIAL17

Key Takeaway Important point is that during this process neither PMOA nor OCP determines or dictates the cGMP Part 4 compliance approach (i.e., streamlined or not), that is the company’s decision

Regulatory Considerations for Medical Device-based GMPs – Choosing the Streamline Approach Mary C Getz, PhD VP, Quality – NSF Medical Device Consulting

cGMP Requirements to Meet Combo Products Regs 21 CFR 4.4(b)(1) and 21 CFR 4.4(b)(2) If the Operating Manufacturing Control System is Part 820 (QS Regulation) CGMP RequirementsTitle § Testing and approval or rejection of components, drug product containers, and closures § Calculation of yield § Tamper-evident packaging requirements for over-the-counter (OTC) human drug products § Expiration dating Testing and release for distribution § Stability testing § Special testing requirements § Reserve samples 20

21 CFR 210/211 Requirements Calculation of yield ( ) –Excess or low yields suggest error. Conduct at each phase at which loss may occur, from drug formulation through combination product packaging as applicable/appropriate Stability testing ( ) –Must be conducted for the drug constituent part as incorporated into the combination product 3

21 CFR 210/211 Requirements (continued) Special testing ( ) –Sterility, pyrogenicity, ophthalmic ointment specs, controlled release –Controlled release combination products include drug-eluting stents and transdermal patches Reserve samples ( ) –Representative samples from each lot of combination product –Must include container/closure, which may be device constituent part (prefilled syringe) or be distinct from the device (drug in cartridge for use in auto-injector) 4

Device PMOA: Case Study Drug-Eluting Stent –Amount of data required in submission depends upon existing information on the drug used (existing IND or is it an NDA) and the similarities in exposure/dose –New drugs – full characterization of safety to understand clinical pharmacology issues In vitro studies > PK study > clinical trial with DES 23

Regulatory Considerations for Med Device based GMPs Choosing Streamline Approach If pursuing the streamlined approached based on CFR 820, the following aspects of 210/211 need to be addressed: –When do I Introduce the API into the Design Control process? –Sourcing of the API –Stability – not only the 2 separate but also the drug/device combination –If it is will be sold over-the-counter, then tamper- evident packaging is required 24

Retain Sampling – the challenge for medical device companies is the sample size. What if I am not able to gather 2X? Rationale/justification for why not – document! Laboratory Controls – methods validation is key Process Validation – focused on drug – content uniformity Yield Calculations Special testing – such as sterility or pyrogen testing, if required 25 Regulatory Considerations for Med Device based GMPs Choosing Streamline Approach

Overall GMP Compliance Strategy Build-in the regulatory expectations upfront in order to make both the Regulatory and Quality pathways efficient and effective Establish procedures that meet the both aspects of CFR 210/211 and CFR 820. For those that are unique to just one regulation, be clear in the “SCOPE” on how they apply. If opting out of a particular activity, then justify and document rationale. Cultivate relationships with OCP and the reviewing/approval agency – transparency and openness are key 26

Business Processes and Impact on the Compliance Strategy 27

Business Processes Which Influence the Compliance Strategy Several Business processes which can have a direct impact which combination products compliance approach to pursue. They are: –Product Development Process (PDP) – looks at new product introduction to market – typically companies are focused on EITHER Drug or Device but not the combination until much later downstream –Strategic Planning – 3 to 5 years to review product pipeline and manage their portfolio –Sales & Ops Planning – resources planning as well as discussions regarding internal vs. external sourcing (manufacturing, packaging) 28

Product Development Process Product Development Process (PDP) – new product introductions and line extensions as well as potential new product platforms Critical Inputs that can impact your Compliance Strategy –Complexity of products – drug/device delivery –Product Safety and Performance Risks – is the product high risk or low risk, and does the combination of the drug/device impact the risk status? – implantable device or chemotherapeutic drugs –Line extensions – are you looking at new markets, different demographics that would require a dosing change or device modification? –Novel approach – new drug or device entities –Acquisition of products – impact on pipeline development and sourcing (external manufacturing) 29

Strategic Planning A company should, at minimum, spend time at their Strategy Planning meeting(s) to determine the following: –Are they a combination products manufacturer and document as such –If so, how to address the product pipeline (future) as well as legacy products –If not, but intend to be there, plan a strategy to address the c ombination production regulations 30

Sales & Ops Planning Sourcing Decisions which can and will impact Compliance Strategy –Is Manufacturing being done onsite or outsourced? –The complexity of drug/device as well as the associated Manufacturing processes –Size and complexity of manufacturing facility –Supplier Selection: Does the Manufacturer have GMP processes in place to support combination products? Resource Planning –Skills and experience of personnel –Training program 31

Part 4 Implementation Challenges Organizations have struggled in their approach to addressing the Regulations as seen below: –During the past 2 years, some companies have had a “knee jerk” reaction to the Part 4 regulations – fire, aim, ready –Lets do it ALL at once, instead of a systematic approach – what makes sense based on the direction the company is headed –Head in the sand – “we have always done it this way, why change, it is TOO much $$ – we will wait for a regulatory action to change” –We aren’t a combo product so these requirements don’t apply to us (repackagers) 32

Conclusion and Summary cGMP Compliance Roadmap – streamline or not –Product type and positioning (PMOA) –Regulatory approach (cGMP compliance focus, where are your strength(s) and experience?) –Product complexity and risk profile –Strategic planning (supply chain, product pipeline) –Relationship with Agency – work with them throughout the process – NO SURPRISES! FINALLY – it is YOUR CALL – make whatever you decide work for you 33
