The 120 people were for both leukemia, lymphoma and solid tumor. They originally planned to enroll 60 for each group. The enrollment for leukemia and lymphoma is not complete. During the conference, CEO mentioned they have 50+ patients for leukemia and lymphoma according to my memory. But because of the ODAC's criticism of their solid tumor data, they will talk to FDA to see 60 is still a satisfactory number. The drug has to be significantly better than the control to achieve statistically significance in 60 patients.

I am confused about one thing. On one hand, they said Depocyt achieved 60% response in lymphoma, while ara-C alone had 10% response; on the other hand, they said interim analysis of clinical trial data is a no-no. So are these numbers from phase II? They commented the 10% was lower than other people had seen.

The difference between "intend to treat" and "evaluable" cost the company this failure and a surprising financial loss to shareholders. I don't think CEO gave us a satisfactory explanation. He was a little irritated and said they chose evaluable patients based on some predetermined critria. But why were there 7 not evaluable in the experimental group and there was only 1 in methotrexate group? Was that because of increased toxicity and side effects? He didn't give a detailed explanation and this would cause some suspicion that cherry picking of the patients was involved. That kind of irresponsible and argumentitive attitude is worrisome.
