The ICH E17 Guideline on Multi-Regional Clinical Trials reaches Step 2b of the ICH Process in June 2016 and now enters the consultation period (Step 3). This new ICH Guideline is proposed to provide guidance on general principles on planning/designing a Multi-Regional Clinical Trial (MRCT).
There are currently no ICH guidelines that deal with the planning and design of multi-regional clinical trials (MRCTs = clinical trials conducted in more than one region under a single protocol). The present guideline describes the principles for planning and design of MRCTs+ in order to increase the acceptability of MRCTs by multiple regulatory authorities. The guideline emphasizes that, at the moment, "it may be challenging both operationally and scientifically to conduct a drug development programme globally, in part due to distinct and sometimes conflicting requirements from regulatory authorities. At the same time, regulatory authorities face increasing challenges in evaluating data from MRCTs for drug approval. Data from MRCTs are often submitted to multiple regulatory authorities without a previous harmonised regulatory view on the study plan."
The present guideline "may facilitate a more efficient drug development and provide earlier access to medicines. In addition, MRCTs conducted according to the present guideline may enhance scientific knowledge about how treatment effects vary across populations and ethnicities under the umbrella of a single study protocol. This information is essential for simultaneous drug development to treat a broad patient population."
Basic Requirements and Key Considerations for MRCTs are:
It is recommended to have scientific consultation meetings, early in the planning stage, with the different regulatory authorities involved, and to obtain their agreement with the proposed overall development plan and the acceptability of MRCT data to support marketing authorization.
