I think I finally understand the data for the optimized patients. If I got anything wrong please correct me.

In the last newsletter there were 18 patients who had received an optimized treatment.

The 90 day data for those 18 patients was as follows:

44% CR (8 patients)
11% partial response (2 patients)
39% pending (7 patients)
6% no response (1 patient) 

We were waiting to find out what happened to those 7 pending patients. Would they also be CR at 90 days? Since then 5 more patients have been treated so now there are 23 patients with an optimized treatment and since there are now 3 patients pending, 2 of the 5 reached 90 days so there are 9 more patients at the 90 day mark than there were at the time of the last newsletter. Here are the results for the 23 optimized patients.

The 90 day data for the current 23 optimized patients is as follows:

52.2% CR (12 patients)
17.4% partial response (4 patients)
13 % pending (3 patients)
The news release does not explicitly tell us how many non-responders there were, but 23-19=4 therefore:
17% no response (4 patients)

Of the 9 patients who reached 90 days since the last report 
44% CR (4 patients)
22% partial response (2 patients)
33% no response (3 patients)

As the news release makes explicit there is still the potential of 82.6 CR at 90 days for the 23 optimized patients (52.2% CR + 17.4% PR + 13% pending)
