From Russia with (3 to 20 times more) Love

Russia’s Clinical Trials are a Thriving Business”, trumpeted the news release that came to my inbox the other day. Inside was a rather startling – and ever-so-slightly odd – claim:
NPR Marketplace Health Desk Reporter Gregory Warner uncovers the truths about clinical trials in Russia; namely, the ability for biopharmaceutical companies to enroll patients 3 to 20 times faster than in the more established regions of North America and Western Europe.
Of course, as you might expect, the NPR reporter does not “uncover” that – rather, the 3 to 20 times faster “truth” is simply a verbatim statement from the CEO of ClinStar, a CRO specializing in running trials in Russia and Eastern Europe. There is no explanation of the 3-to-20 number, or why there is such a wide confidence interval (if that’s what that is).

The full NPR story goes on to hint that the business of Russian clinical trials may be a bit on the ethically cloudy side by associating it with past practices of lavishing gifts and attention on leading physicians (no direct tie is made – the reporter however not so subtly notes the fact that one person who used to work in Russia as a drug rep now works in clinical trials). I think the implication here is that Russia gets results by any means necessary, and the pharma industry is excitedly queuing up to get its trials done faster.

However, this speed factor is coupled with the extremely modest claim that clinical trial business in Russia is “growing at 15% a years.” While this is certainly not a bad rate of growth, it’s hardly explosive. It’s in fact comparable to the revenue growth of the overall CRO market for the few years preceding the current downturn, estimated at 12.2%, and dwarfed by the estimated 34% annual growth of the industry in India.

From my perspective, the industry seems very hesitant to put too many eggs in Eastern Europe’s basket just yet. We need faster trials, certainly, but we need reliable and clean data even more. Recent troubling research experience with Russia -- most notably the dimebon fiasco, where overwhelming positive data in Russian phase 2 trials have turned out to be completely irreproducible in larger western trials –has left the industry wary about the region. And wink-and-nod publicity about incredible speed gains probably will ultimately hurt wider acceptance of Eastern European trials more than it will help.

1st-Person Accounts of Trial Participation

Two intriguing articles on participation in clinical trials were published this week. Both happen to be about breast cancer, but both touch squarely on some universal points:

ABC News features patient Haralee Weintraub, who has enrolled in 5 trials in the past 10 years. While she is unusual for having participated in so many studies, Weintraub’s offers great insights into the barriers and benefits of being in the trial, including the fact that many benefits – such as close follow-up and attention from the treatment team -- are not obvious at first.

Meanwhile, the New York Times’ recurring column from Dr Peter Bach on his wife’s breast cancer offers a moving description of her consent into a trial. His essay focuses mainly on the incremental, slow pace of cancer research (“this arduous slog”) and how it is both incredibly frustrating and absolutely necessary for long-term improvements in treatment.

Realistic Optimism in Clinical Trials

The concept of “unrealistic optimism” among clinical trial participants has gotten a fair bit of press lately, mostly due to a small study published in IRB: Ethics and Human Research. (I should stress the smallness of the study: it was a survey given to 72 blood cancer patients. This is worth noting in light of the slightly-bizarre Medscape headline that optimism “plagues” clinical trials.)

I was therefore happy to see this article reporting out of the Society for Surgical Oncology. In looking at breast cancer outcomes between surgical oncologists and general surgeons, the authors appear to have found that most of the beneficial outcomes among patients treated by surgical oncologist can be ascribed to clinical trial participation. Some major findings:
  • 56% of patients treated by a surgical oncologist participated in a trial, versus only 7% of those treated by a general surgeon
  • Clinical trial patients had significantly longer median follow-up than non-participants (44.6 months vs. 38.5 months)
  • Most importantly, clinical trial patients had significantly improved overall survival at 5 years than non-participants (31% vs. 26%)

Of course, the study reported on in the IRB article did not compare non-trial participants’ attitudes, so these aren’t necessarily contradictory results. However, I suspect that the message of “clinical trial participation” entails “better follow-up” entails “improved outcomes” will not get the same eye-catching headline in Medscape. Which is a shame, since we already have enough negative press about clinical trials out there.
