The purpose of this note is to:

(1) Reconcile the past ODAC meeting

(2) Present a FORMAT for understanding the
current Phase 3 testing of DepoCyt vs
Leukemia & Lymphoma & Solid Tumors

I realize many already understand
what has happened, so please move on,
I'm just making sure I understand what has
happened and what will happen.

In addition, it may help just 1 more stockholder.

Regards,

John

Notes:

(1) DEPO Mgmt. REFUSES to explain the 7 people
they termed Not Evaluable.

(2) To steal a line from BIAO LUO - is DEPO Mgmt. CHERRY PICKING the
Control Population.

(3) (2) calls into question the VERACITY of DEPO Management.

(4) The WORST side effects occurred with Methotrexate usage.
1 Death and 1 CNS.

(5) Doctors who offered opinions on their review included
Richard Simon , Steve Hirschfeld , Sandra Swain and
Derek Ragavan.

(6) The final vote was 7 against and 3 for.
