Cytel's new Trial Innovations Webinar Series provides a platform for the most promising new statistical approaches helping to bridge the gap from methodology to implementation. Ultimately, our goal is to enable our audience to improve their chances of success in clinical development.

The series got underway in August with a webinar on ‘Phase 2 Trial Designs using Program-level Simulations, and Possible Adaptive Approaches’.

Cost of pharmaceutical development and R&D productivity is an ongoing industry concern, consistently discussed in the mainstream and specialist press.  The issue is held in delicate balance against the increasing pressure on pharmaceutical pricing and cost containment measures.

A study by Tufts Center for the Study of Drug Development published earlier this year in the Journal of Health Economics (1) provides new estimates of R&D costs, building on previous work in the area.

How to Shorten a Cardiovascular Outcome Trial By Two Years

Cardiovascular outcome trials (CVOTs) have earned the reputation of being the untamable behemoths of the clinical world. Needless to say these trials are long and require extremely large sample-sizes. The Contrave LIGHT study required 8900 patients. The SAVOR TIMI trial enrolled 16,492 patients. Even the EXAMINE trial, which benefited from a promising zone design, required 650 patients. 

However, since the explosive controversy over the FDA’s conditional approval of anti-obesity drug Contrave four years ago, there is much we have learned about how to make these trials shorter while also diminishing the financial risks of investing in them. For example, one of our clients managed to shorten the expected study length of an a CVOT by two years using a four point MACE Assessment (see below). 

In this post, we explore some of the lessons we have learned when designing these large-scale clinical trials.

5 Scenarios When ‘Keep it Simple’ May Be Bad Advice for Clinical Trial Designers

Posted by Esha Senchaudhuri

When designing clinical trials, many trial designers are advised to keep the trial simple. Prima facie, the keep it simple principle seems like sound advice. There are various logistical uncertainties that arise when implementing a clinical trial, and the more simple a trial – so conventional wisdom says – the easier it is to respond to these uncertainties.

According to Zoran Antonijevic, a Senior Director at Cytel Consulting, there is reason to doubt such conventional wisdom. After all, flexibility is hardly a virtue of a traditional trial design. Simple designs may seem to make it easier to monitor data and report results. However, a flexible design can better address remaining uncertainties in product development. These uncertainties are related to treatment effect, dose selection, or a sub-population that would experience the best benefit/risk from the treatment.

Impact of Study Design and Development Strategy on Pharmaceutical Programs and Portfolios

Posted by Esha Senchaudhuri

As more clinical trials make use of adaptive designs, investors have come to realize that high quality trial designs can result in significant improvements to a trial’s financial risk profile. Regardless of a trial’s eventual success or failure, a well-constructed design provides a drug with the highest possible probability of success while mitigating financial risk.
