The Regional Roadblock: Navigating Comparator Sourcing Challenges in Global Clinical Trials

The Regional Reference Standard Dilemma

Why is comparator sourcing a critical factor in global clinical trials?

Comparator sourcing directly impacts the regulatory approval process and clinical trial timelines. Many regional regulators require that reference drugs (RLDs) used in bioequivalence (BE) studies be sourced locally, making it a strategic, not just logistical, decision.

What challenges do pharmaceutical companies face when sourcing comparators for ASEAN countries?

ASEAN regulators often reject BE studies that use RLDs sourced outside the ASEAN region. Companies must also navigate local climate, stability conditions, and market-specific formulation requirements, complicating dossier submissions.

Can USFDA or EMA-approved comparators be used in emerging markets?

Not always. While the USFDA and EMA offer more flexibility, many emerging market regulators (like those in ASEAN or Latin America) require locally sourced comparators, regardless of prior global approvals.

What strategies can companies use to overcome comparator sourcing hurdles?

Effective strategies include early market analysis, maintaining regulatory intelligence, sourcing acceptable generics when innovators are unavailable, thorough documentation, and collaborating with local experts familiar with regional requirements.
