摘要

Purpose

The regulatory landscape in rare diseases and oncology has evolved to address unmet medical needs by implementing expedited approval pathways. The US FDA’s Accelerated Approval and the EMA’s Conditional Marketing Authorization facilitate earlier patient access to therapies through reliance on surrogate endpoints derived from early-phase clinical trials. The review aims to provide a comprehensive review of the role and utilization of surrogate endpoints in accelerated drug approvals, highlighting their strengths, limitations, and the varying perspectives of stakeholders on their validity and utility.

Methods

This article reviews existing literature and regulatory guidelines to assess the effectiveness and challenges associated with surrogate endpoints in expedited approval pathways. It also examines the post-approval commitment adherence required by regulatory bodies, exploring discrepancies among stakeholder perspectives.

Results

Findings indicate that while surrogate endpoints enable faster market access, uncertainties remain regarding post-approval commitments and their consistency. Differences in stakeholder opinions also persist, reflecting varying levels of confidence in the validity and applicability of surrogate endpoints.

Conclusion

Surrogate endpoints play a crucial role in accelerating drug approvals in areas with high unmet needs, yet challenges around post-approval commitments and stakeholder acceptance suggest the need for enhanced regulatory clarity and ongoing assessment of surrogate endpoint validity.
