How Asian Ethnobridging Trials Can Shorten Drug Development Timelines
If your organization intends to develop drugs for the Asian market, you may need to repeat Phase 1 studies in regions outside of North America or Europe—or with your current CRO if they have the right participant populations. This research can help you determine whether the drug’s pharmacokinetics are the same in different ethnic groups. If your organization wants to demonstrate biosimilarity in drug products between Asian and non-Asian populations, consider performing Asian ethnobridging trials. When you decide to incorporate ethnobridging into your project during early clinical development, you can save time and help your budget. Here’s how.
What Is Ethnobridging?
Ethnobridging means using a local target population for a study during
Phase 1. Instead of needing to repeat studies in the target region, your
organization can recruit participants in “global” safety and efficacy
trials using a Phase 1 ethnobridging strategy. The Phase 1 development
won’t have to be repeated for Phases 2 and 3, making it possible to use
the same Phase 1 clinical trial units without finding other units globally. This can help reduce drug development timelines, often by years.
Why Should You Perform Ethnobridging?
More than half of the world’s population is genetically Asian. Within
the many Asian subgroups are known differences in pharmacogenetics and
previously identified variants. These are significantly more or less
prevalent in Asian populations compared to other populations. In the
past, this meant timelines for drugs developed in Asia differed from
Western regions. Time lag could last for years. While some of these
problems have been addressed in the past few decades, it is still easier
to perform ethnobridging locally as opposed to multiple studies
worldwide.
Bridging Data with ICH E5 Guidance
Another strategy for addressing this lag was with the International
Council for Harmonisation of Technical Requirements for Pharmaceuticals
for Human Use (ICH) issuing the ICH E5 guidelines. Drug development
sponsors must have a complete clinical data package. This includes
adequate characterization of PK/PD, safety and efficacy, and a clear
definition of dose response. Authorities will also review
region-specific medical and diagnostic approaches. Once it passes this
step, your organization can consider a bridging strategy for
implementation.
ICH E17 Guidance
ICH
E17 provides further guidance, giving context for multi-regional
clinical trials (MRCTs) that support global drug development. These
guidelines include genomic sampling, the use of good clinical practice,
and statistical principles for control groups and sample sizes. MRCTs
that follow E17 allow for investigation of treatment effects, such as
safety evaluations in the overall population. It can also facilitate
submitting marketing authorization applications to multiple regulatory
authorities in different regions simultaneously. This can provide
earlier access to new drugs worldwide.
Accelerating Asian Drug Development Through Ethnobridging
Depending on the region of Asia you’ve decided to target, your drug
development may only need to perform Phase 2 studies and beyond in the
target regions. Phase 1 studies could be done in the U.S. with an
ethnobridging strategy. FIH, SAD/MAD, and ethnobridging trials can be
conducted in the U.S. if your drug is developed for all Asian markets
simultaneously. Target development regions and ethnobridging strategies
can be identified, with further decisions following consultations with
regulatory authorities across the regions.
