Not aware of ANY pivotal phase III trial underway. I just checked clinicaltrials.gov and they show that a non-pivotal, phase III is just recruiting now but has not started. If all goes on schedule, it is expected to be completed in 3 years in December 2015.
And understand it is phase III trials where most drugs fail. They are very high risk.
