I’ve been writing in CRfocus about the ongoing globalisation of clinical research for so long that I’m sure many of you reading this know my starting point very well:
- That increasing globalisation is inevitable as a strategic result of shifts in demographics of patient groups and capability of societies to pay for medicines;
- That this shift has been accelerated by tactical advantages around speed and cost of conducting clinical trials; and
- That, provided these clinical trials are conducted with cultural sensitivity and to globally accepted standards of procedural and data quality, this is a ‘good thing’.
But how close is the correlation between the buzz and the truth? There is undisputed interest in many “emerging” countries, but how long is it taking for reality to catch up? Indeed, when we say global, do we really mean global at all?
Recently, I chaired a stream on “managing study globalisation” at the first ICR Symposium. Speakers and delegates alike shared their experiences, interest and commitment to carrying out “global” clinical trials for good ethical, practical and commercial reasons. Many countries were mentioned, and many details were discussed around the intricacies of working in the BRIC countries (Brazil, Russia, India and China) etc. I gave a presentation to close the stream, sharing an analysis I had done of the locations of studies listed in www.clinicaltrials.gov. My conclusion was that, while the pool of countries being used in clinical trials is certainly expanding, and increased attention on these emerging locations is certainly justified, the rate of change is perhaps slower than many might think, and the pool of countries is only expanding by a relatively modest amount.
I compiled a list of the top 25 countries mentioned in all studies in the registry and compared it with studies registered since 2009. While the ranking was altered, there was only one change in the countries listed (Hungary replacing Norway) and the BRIC countries were in both lists (albeit in the bottom half). Re-analysing the data again, to adjust for the absolute number of studies carried out in each country since 2009, only brought relatively minor changes in the composition of the top 25 countries, with a slight shift from Western Europe to Eastern Europe and the BRIC countries remaining outside the top 10 (although with Korea jumping up to 4th). When I asked delegates to highlight any countries they had worked in that were not in this list, only a few suggestions were given, and these were mostly in the next 25 in the ranking model.
So, while 146 countries around the world have hosted at least one clinical trial, the “global” operations of many pharmaceutical companies may well be constrained to only 50 countries, or perhaps more like 35, where it is logistically practical, commercially viable and of regulatory relevance.
There is one fairly major caveat to this analysis: the data I used was at a study level, rather than considering the distribution of sites or even patients within a study. This would mask the impact of studies still conducted in the USA or Western Europe, but with a substantial shift in the proportion of patients recruited from Eastern Europe, Asia-Pacific and Latin America, which is widely considered to be the case.
So, globalisation is increasing, is here to stay, and is a good thing. But, for the moment at least, the pool of countries we are working in routinely is still relatively small. As we gain experience of working in a wider pool of countries, and investigational site teams in those countries gain more experience of working to global standards, these metrics will continue to shift… but possibly somewhat slower than we might expect.
