Good to see you back. Forgot mention that Xoma says DSMB will review again after 130 people have been treated. So need 50 more to get to that point from the 80 number st released.Perhaps from a business point of view it is better that the trials have continued. As some of your past post have indicated the determination of statistical significance is complex but the larger the sample the less doubt will exist as what the results actually mean.

Even when the sample is large as in the CORR drug, great debate can rage over the significance of less than strong results. Therefore, perhaps more is better since even "strong" results with a small sample might not seem important to many market players as indeed was the case with the open trial of just 26.
