Using Real-World Evidence in Biologics and Biosimilar Lifecycle Management

In recent years, real-world evidence (RWE) has emerged as a critical factor in the regulatory landscape surrounding biologics and biosimilars. The foundations of regulatory affairs encompass a range of complex interactions between research, development, and post-marketing surveillance. This article provides an in-depth examination of the use of RWE in the lifecycle management of biologics and biosimilars, aligning with the expectations of regulatory bodies such as the FDA, EMA, and MHRA. This is an essential read for regulatory affairs professionals, CMC, and labeling teams within the pharmaceutical sectors of the US, UK, and EU.

Context

Regulatory Affairs (RA) serves as a bridge between the pharmaceutical industry and regulatory agencies. It ensures that products comply with the relevant laws and regulations throughout their lifecycle, from development to post-market surveillance. In the realm of biologics and biosimilars, the integration of RWE into decision-making frameworks has gained prominence. RWE is defined by the FDA as the clinical evidence derived from the analysis of RWD (real-world data) concerning the usage and benefits of a medical product. This can include data generated from electronic health records, claims and

billing activities, product and disease registries, and patient-reported outcomes.

Legal/Regulatory Basis

The legal frameworks governing the use of RWE can be found within several key regulations and guidelines:

  • 21 CFR Part 312: This outlines the regulations for Investigational New Drug Applications (IND), which may include requirements for RWE in demonstrating safety and efficacy.
  • 21 CFR Part 601: Applicable to biologics, this regulation lays the groundwork for licensing biological products. It offers flexibility for including RWE in applications for biologics and biosimilars, particularly in post-approval settings.
  • ICH E9 and E17 Guidelines: These guidelines speak to the use of statistical principles and considerations in the design and interpretation of clinical trials, including how RWE can complement data obtained from trials.
  • FDA’s Real-World Evidence Framework: This strategic framework emphasizes the importance of RWE in regulatory decision-making, especially in assessing the effectiveness of medical products post-marketing.
  • EMA’s Guideline on the Use of RWE: This document provides insights on how RWE may support the development and lifecycle management of medicines, including biosimilars.

Documentation

The effective use of RWE in regulatory submissions necessitates comprehensive and robust documentation strategies. Regulatory professionals must consider the following:

  • Quality of Data: Ensure that the real-world data utilized is of high quality. This includes the validity of sources, methods of data collection, and the relevance of the collected data to the product in question.
  • Study Design: Clearly outline the study designs employed in RWE analyses. This includes observational studies, registry data, and pragmatic trials, detailing how these designs fit into the regulatory framework.
  • Statistical Analysis: Provide a detailed explanation of the statistical methodologies utilized to analyze RWD. This should align with the ICH E9 guidelines concerning the use of statistical data in drug development.
  • Rationale for Use: A clear rationale for utilizing RWE as part of the evidence base for approval or lifecycle management decisions must be documented. This should reference specific regulation clauses and demonstrate how RWE fills existing gaps in traditional evidence.

Review/Approval Flow

The integration of RWE into regulatory submissions follows a distinct review and approval pathway, which includes several decision points:

  1. Pretreatment: Before conducting a clinical trial or submitting an application, assess whether existing RWD can fill knowledge gaps or whether prospective data collection is required.
  2. Initial Submission: When submitting applications, including biologics license applications (BLAs) or marketing authorization applications (MAAs), clearly specify plans for incorporating RWE.
  3. Agency Interactions: Engage in pre-submission meetings with regulatory agencies. This is crucial for discussing how RWE will complement clinical trial data and including it within the submission package.
  4. Post-Market Surveillance: Post-approval, establish a plan to gather RWE consistently, demonstrating the ongoing effectiveness and safety of the biologic or biosimilar.

Common Deficiencies

When utilizing RWE in regulatory submissions, there are common deficiencies that regulatory professionals should be cognizant of:

  • Insufficient Evidence: RWE should not be perceived as a replacement for clinical trial data. Regulatory agencies expect RWE to complement and provide insights into data generated from strict clinical protocols.
  • Poor Study Quality: Submissions that lack rigorous methodologies in RWE generation are likely to be met with scrutiny. Transparent reporting of data handling, analysis, and conclusions is essential.
  • Failure to Engage with Regulatory Bodies: Not proactively engaging with regulatory agencies can lead to unexpected outcomes. Pre-submission interactions and consultations can clarify expectations and align strategies early on.

RA-Specific Decision Points

Determining when and how to incorporate RWE into the regulatory process involves critical decision points that require careful consideration:

1. Filing as Variation vs. New Application

One of the significant decisions in RA is whether to file for a variation or a new application. When considering RWE, the following scenarios may arise:

  • If substantial changes are made to the biologic: This might necessitate a new application where robust RWE data must be generated to support the modified indications or claims.
  • For minor modifications: If the changes do not significantly alter the product’s safety or efficacy profile, then a variation might suffice, supported by relevant RWE.

2. Justifying Bridging Data

Bridging data refers to the use of RWE to support claims made in a new geographical market based on existing clinical data. When justifying the use of bridging data, consider:

  • Relevance to the local population: Ensure that the RWD used provides sufficient insights into the drug’s performance and safety in the new demographic.
  • Methodological Fit: Clearly justify the methodologies used to derive conclusions from RWE, ensuring alignment with local regulatory expectations.

3. Specific Expectations by Agency

Agencies such as the FDA, EMA, and MHRA have individual expectations for the incorporation of RWE. Engaging with agency-specific guidelines ensures compliance:

  • FDA’s Expectations: The FDA encourages the submission of RWE to provide insights into the effectiveness of therapies in broader, more variable populations.
  • EMA’s Focus: The EMA is particularly concerned with using RWE as post-marketing evidence to assess long-term safety and efficacy.
  • MHRA Guidelines: The MHRA highlights RWE’s role in informing the risk-benefit assessments in the context of patient populations that may differ from those in clinical trials.

Practical Tips for Documentation, Justifications, and Responses

To facilitate the effective incorporation of RWE within regulatory submissions, RA professionals should consider these practical tips:

  • Clear Protocols: Develop clear, documented protocols for how RWE will be generated and analyzed, ensuring consistency across all documentation.
  • Thorough Justifications: When presenting RWE, include detailed justifications for its relevance and appropriateness to support regulatory decisions. This includes comparison to traditional clinical trial data and how RWE adds value.
  • Continuous Engagement: Establish ongoing communication with regulatory bodies regarding RWE initiatives. Continuous feedback helps refine strategies to align with regulatory expectations.
  • Training and Education: Ensure that all team members involved in the RWE process are well-informed about regulatory requirements and best practices in data utilization.
