Product and Process Transition Support

Customers looking to transition into a new West product or process need to start with an evaluation of the likely impact of the change to their regulatory files. This is key to building an efficient regulatory submission strategy that will maximize approvability and minimize the time required to achieve approvals.

West RA can provide customers with regulatory assessments to identify potential regulatory risks, suggest mitigation strategies, and provide references to relevant guidances for support. West regulatory assessment documents can provide customers with the tools needed to help build an overall regulatory submission strategy and facilitate the transition.

Global Compliance Certifications

Regulatory Affairs provides customers with Regulatory Compliance Certificates to verify that West products and processes meet regulatory agency expectations in all major markets.

Examples of compliance certification letters include:

  • Direct/Indirect Food Contact Regulations
  • Materials of Animal Origin (TSE/BSE Risk Evaluation for Raw Materials)
  • Heavy Metals (Toxics in Packaging Legislation)
  • Natural Rubber Latex/Dry Natural Rubber Content

Drug Master Files

West maintains an extensive portfolio of Drug Master Files (DMFs), Master Access Files (MAFs), 510ks and Canadian Licenses with both the FDA and Health Canada.

Upon request, West can provide Letters of Authorization/Access (LOAs) to customers for inclusion in their drug applications.

Each year, West provides over 1800 LOAs to its DMFs, using a convenient online request form. West RA has worked with both FDA and Health Canada to define industry standards for conversion of packaging and process DMFs to electronic format (eCTD). The entire West DMF portfolio has been converted to eCTD, so that files are compliant with FDA and Health Canada requirements for electronic DMFs.

Regulatory Insights

Evaluation of Primary Functions

The concept of primary functions was first introduced in the 2022 revision of ISO 11608, Needle-based injection systems for medical use — Requirements and test methods: Part 1. Primary functions are defined in the ISO 11608-1 standard as a “function or operation of the needle-based injection system, which, if it does not perform to specifications during use, would directly result in a failure to accurately deliver the medicinal product via the correct route and/or directly result in unacceptable harm to the patient.”

Evaluation of Essential Performance Requirements

Determination of essential performance requirements (EPRs) are a critical step in the evaluation of a drug/device combination. EPRs are generally referring to those aspects of the combination product that are critical for device performance during clinical use to achieve its intended function.

Considerations for Medical Device Delivery and Product Classification

As technology evolves to meet the needs of patients, device options are expanded to cover multiple delivery profiles and drug types. In some cases, drugs may require reformulation in order to move a therapy that is traditionally provided via a large volume infusion to something that could be provided in a handheld device or an on-body delivery system (OBDS). This process can result in a range of delivery volumes, viscosities and dose delivery profiles (time and rate).

Special 510(k) Program Pilot Overview

On October 1, 2018, the Food and Drug Administration (FDA) launched the Special 510(k) Program Pilot, which aims to expand on the types of changes eligible for the program to improve the efficiency of 510(k) review.  

Devices Proposed for a New Use with an Approved, Marketed Drug; FDA Public Hearing

Medical products are often intended and labeled for use in conjunction with other medical products marketed by different sponsors. In some cases, the medical products are of different types. Typically, the different sponsors collaborate when the two products are to be used together for a new intended use. however, sponsors seek marketing authorization from FDA for a medical product for a new use with the approved, marketed medical product of another sponsor, and the sponsor of the approved, marketed product does not wish to pursue the new use or work with the other product sponsor.  

Determining Whether to Submit an ANDA or a 505(b)(2) Application Overview

The Drug Price Competition and Patent Term Restoration Act of 1984 (Public Law 98-417) (Hatch-Waxman Amendments) added section 505(b)(2) and 505(j) (Abbreviated New Drug Application (ANDA) to the FD&C Act, which describe abbreviated approval pathways. With the passage of the Hatch-Waxman Amendments, the FD&C Act describes different routes for obtaining approval of two broad categories of drug applications: new drug applications (NDAs) and abbreviated new drug applications

Appropriate Use of Voluntary Consensus Standards in Premarket Submissions for Medical Devices FDA Guidance

Voluntary consensus standards can be a valuable resource for industry and FDA staff. The use of  consensus standards can increase predictability, streamline premarket review, provide clearer regulatory expectations, and facilitate market entry for safe and effective medical products. 

Impact of GDUFA II Fee Structure on Generic Drug Change Evaluation

GDUFA II becomes effective on October 1, 2017, bringing significant changes to the user fee structure. Some of these changes may provide incentives for generic drug manufacturers to pursue manufacturing upgrades that may have previously been prohibitive.

Human Factors Considerations in Combination Product Design and Development

Human factors studies plays a key role in maximizing the likelihood that the device will be safe and effective for use by the intended users and environments.

Unannounced EU Medical Device Audits by Notified Bodies: Impact on Suppliers 

European medical device licensing regulations permit Notified Bodies to evaluate manufacturers and suppliers for conformance to quality standards. Suppliers identified as critical may be subject to announced and unannounced audits and must comply or risk jeopardizing the device manufacturer’s license.
