Biomira announces final Phase 2b survival results of Stimuvax(R) (formerly known as BLP25 Liposome Vaccine) trial in patients with non-small cell lung cancer

· Issued by Skrr Exploration, Inc. via CNW
Results confirm median survival of 30.6 months in stage IIIB patients on 
vaccine versus 13.3 months in control patients

EDMONTON, April 28 /CNW/ - Biomira Inc. (Nasdaq:BIOM) (TSX:BRA) today
announced final survival results from an exploratory analysis of the Phase 2b
clinical trial data. The randomized, open-label trial tested the clinical
potential of Stimuvax(R) in patients with Stage IIIB and IV non-small cell
lung cancer (NSCLC). The analysis confirms a median survival in Stage IIIB
patients on vaccine being 30.6 months, while Stage IIIB patients on the
control had a median survival of 13.3 months.
"Our enthusiasm around Stimuvax(R) continues," said Alex McPherson, MD,
PhD, President and CEO of Biomira. "These data from the Phase 2b trial are
encouraging and have been reviewed by an independent statistician, who
confirms our findings. We are in the process of completing the transition of
this exciting project to Merck KGaA of Darmstadt, Germany and we have begun
manufacturing the vaccine required for the phase 3 study slated to start this
summer. We are hopeful that this larger randomized trial will confirm the
results seen in the phase 2b trial."

Stimuvax(R): Clinical Study Design and Results of Additional Analysis
The controlled, open-label Phase 2b trial enrolled 171 men and women with
NSCLC whose disease was stable or who had responded to treatment following
completion of their first-line standard chemotherapy with or without radiation
therapy. Patients were randomized to either Stimuvax(R) plus best supportive
care or to best supportive care alone. Best supportive care includes
palliative radiation therapy and/or second line chemotherapy according to
current standard clinical practice. The study was designed to document the
safety profile of the vaccine and to evaluate efficacy by comparing survival
in the two arms.
An earlier survival analysis reported in November 2004, indicated that
the median survival in the pre-stratified subset of locoregional Stage IIIB
patients on the vaccine arm had not been reached. Informal survival results
from an additional exploratory analysis have now been confirmed showing a
median survival in the Stage IIIB patients on vaccine being 30.6 months, while
the Stage IIIB patients on the control had a median survival of 13.3 months.

Stimuvax(R)
Formerly known as BLP25 Liposome Vaccine (L-BLP25), Stimuvax(R) is a
synthetic MUC1 peptide vaccine. Stimuvax(R) incorporates a 25-amino acid
sequence of the MUC1 cancer mucin, encapsulated in a liposomal delivery
system. The liposome enhances recognition of the cancer antigen by the immune
system and facilitates better delivery. Stimuvax(R) is designed to induce an
immune response to cancer cells.
