Al's Comment:

 This is mostly good news about the DCVax trial.  This is one of my favorite trials. There are 2 major announcements:

1.  The patients on the compassionate use arm of the trial seem to have done much better than expected.  These patients had the vaccine made but were excluded from the trial because they had a recurrence before the trial could actually start.   These patients usually die quickly but the vaccine seemed to help those.

2. They have changed the number of patients in the trial, as well as the point in time when they evaluate the trial.  This may be good or bad - hard to tell. The good point is that will increase the chances that the trial shows positive results, however it is going to delay the results - maybe by a year.  As the ICT-107 trial showed, when you look at the results too early, you can't see the effect the treatment has on the "tail" - the number of people who do well for a long period of time. You just see the people who did not respond to the treatment.

Trial Progressing On Track;55 Patients In Compassionate Use "Information Arm" Showing Encouraging Survival
BETHESDA, Md., Aug. 11, 2014 /PRNewswire/ -- Northwest Biotherapeutics NWBO -1.63%  (NW Bio), a biotechnology company developing DCVax® personalized immune therapies for solid tumor cancers, announced an update about the Company's Phase III clinical trial of DCVax®-L for Glioblastoma multiforme (GBM) brain cancer in conjunction with the Company's separate announcement today about certain changes to the Phase III trial.  The update from the Company reported that the trial is progressing on track, and that 55 patients who were not eligible to enroll in the trial due to unusually rapid tumor recurrence were included in a compassionate use "Information Arm" and are showing encouraging survival times.
The Phase III trial is enrolling patients at over 50 trial sites in the US and a number of sites in the UK and Germany, and is progressing in accordance with industry norms.  The current trial plan involves enrollment of 312 total patients in the trial, and counting 110 "events" of tumor recurrence or patient deaths from among these 312 patients to determine whether the primary endpoint of the trial is met.  As announced separately today, the Company is modifying its trial plan so that it will enroll 348 total patients, and will count 248 "events" from among these 348 total patients to determine whether the primary endpoint of the trial is met.  So, the number of "events" counted in the statistical analysis will increase from 110 to 248, but the total enrollment in the trial will only increase from 312 to 348.
During 2011 and 2012, in addition to conducting the trial, the Company also treated 55 GBM patients with DCVax-L on a compassionate basis in an "Information Arm" outside of the Phase III trial.  These 55 patients received the same DCVax-L treatment regimen used in the trial, at medical centers participating in the trial.  The 55 patients were not eligible for the Phase III trial because they were either definitely or potentially "rapid progressors": patients with such an aggressive form of GBM that their tumor was already re-growing during the 6 weeks of daily radiation to the brain and daily chemotherapy which followed the surgical removal of their original tumor as part of the current standard of care. 
"Rapid progressors" are usually excluded or segregated in studies and analyses because their disease is so accelerated that it is not comparable to regular GBM patients.  Regular GBM patients survive for a median of about 14.6 months with current standard of care.  "Rapid progressors" have a much shorter life expectancy, in the range of 7 to 10 months, and generally are not expected to respond much to any treatments.
Although the "Information Arm" data were not part of the Phase III trial and were not blinded, the Company did not receive this data until recently, in connection with the changes to the Phase III trial that were also announced today and certain regulatory submissions.
The data received by the Company include the survival to date for all 55 patients in the "Information Arm" and data relating to the progression of their cancer for 43 of the 55 patients.  According to initial analyses, the median Overall Survival for all 55 patients is 18 months;  the median Overall Survival for the 43 patients is a little over 19 months.  The Company is in the process of further analyses of the data on these patients.
In light of the extremely poor prognosis and short survival time of "rapid progressor" patients with standard of care today, the median Overall Survival observed in these patients who received treatment with DCVax-L in the "Information Arm" is unexpected and encouraging.
