**FDA Workshop on***** *****Novel Drug Delivery Systems: Scientific, Clinical and Regulatory Challenges**
- July 8, 2003

## Overview	

- What is a Combination Product?
- Regulation of Combination Products
- Role of Office of Combination Products
- Current Initiatives

## Combination Products

**Question: Are novel drug and biologic delivery systems combination products?**
**Answer: It depends.**** **
**Question: Must a novel drug/biologic delivery system be a combination product to raise complicated regulatory issues?**
**Answer: No.**

## Combination Product

- Combination Product (21 CFR 3.2(e)):
- a product comprised of two or more regulated components that are physically, chemically or otherwise combined or mixed as a single entity;
- two or more separate products packaged together (e.g., drug and device products); or
- A product packaged separately but intended for use only with an approved, individually specified 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.
- (Similar to 3rd bullet but both products investigational)

## Examples of Combination Products

- Device coated, impregnated or otherwise physically/chemically combined with a drug or biologic
- Drug-eluting cardiovascular stent, antimicrobial or heparin-coated catheter, condom with spermicidal coating, pacing lead with steroid-coated tip
- Skin substitutes with cellular components, orthopedic implant with growth factors
- Prefilled drug or biologic delivery device
- Syringes, insulin/epinephrine/interferon injector pens, metered dose inhalers, transdermal patches

## Examples of Combination Products

- Drug or biologic with applicator/delivery device
- Drug-biologic combinations
- Radiopharmaceutical combined with biologic, monoclonal antibody combined with a chemotherapeutic drug, interferon/ribavirin
- Separate products that may constitute combination:
- Hyperthermia device and chemotherapeutic drug, photodynamic therapy drug and laser/light source, diagnostic device requiring administration of a particular drug or biologic, drug requiring specific diagnostic device

##  Not Combination Products

- Drug-drug, device-device, or biologic-biologic combinations
- Most concomitant use of drugs, devices and biologics
- General drug or biologic delivery devices (e.g., unfilled syringe or infusion pump) not intended for use with an individually specified drug or biologic product

## Regulatory Approaches

- Device (CDRH)
- PMA
- 510(k)
- IDE

- Drug (CDER)
- NDA
- IND

- Biologic (CBER)
- BLA
- IND

## Regulation of Combination Products

- Assigned to lead Center based on “primary mode of action”
- Intercenter consultation/collaboration
- Premarket regulatory authorities
- One application vs. two
- Postmarket regulatory authorities

## Office of Combination Products (Established December 24, 2002)

- Assignment of combination products
- Ensure timely and effective premarket review
- Consistent and appropriate postmarket regulation
- Dispute resolution (timeliness vs. substance)
- Review/update guidance, agreements, practices
- Reports to Congress

- P. L. 107-250 -- enacted 10-26-02

## Assignment of Combination Products

- Statute:
- Promptly assign an agency Center
- Goals:
- Efficient RFD process
- More consistent, predictable, and transparent process

## Assignment of Combination Products

- Initiatives:
- Definition of Primary Mode of Action
- Selection of premarket authorities
- 1 application vs. 2
- RFD Process and 21 CFR Part 3
- RFD Precedent Documentation

## Review of Combination Products

- Statute:
- Ensure timely and effective premarket review by overseeing timeliness of and coordinating reviews involving more than one agency Center

## Review of Combination Products

- SOP on Intercenter Consultation Process
_**www.fda.gov/oc/ombudsman/intercentersop.pdf**_
- Monitoring Intercenter Consultations
- Active monitoring/facilitation
- Web-enabled database
- Tracking and Reporting of Other Combinations
- Categorization of premarket submissions
- Resource to sponsors and review staff
- Reviewer tools and training
- Submission format and content

## SOP -- Policy Highlights

- “Consults Count”
- Agency’s work
- Consulted Centers are accountable for:
- quality
- timeliness
- Consulted reviewers receive credit

## Postmarket Regulation

- Statute:
- Ensure consistency and appropriateness
- Initiatives:
- RFD Letters
- GMP’s
- Adverse Event Reporting
- Consultation/communication process for new type of product
- Other Issues (e.g., registration and listing)

## Combination Product Evaluation -- General Considerations

- Elucidate primary mode of action (jurisdiction)
- Considerations:
- Regulatory pathway and questions that need to be addressed for that pathway
- Approaches normally taken by lead Center
- “Additive” effect of the “new” component
- One size doesn’t fit all
- Review guidance documents
- Consult with FDA

## Related Issues

- Advantages of collaboration between device and drug/biologic sponsors
- What if my product is not a combination product – will these initiatives still help?
