Biomira Inc. (BIOM) And Merck KGaA (MKGAF.PK) Present Non-Small Cell Lung Cancer Data At European Society For Medical Oncology Congress (Abstract No. 3IN)


10/19/2005 5:12:02 PM

EDMONTON, ALBERTA and DARMSTADT, GERMANY, Nov. 1 /PRNewswire-FirstCall/ -- Biomira Inc. (TSX: BRA) and Merck KGaA reiterated today that data from the Companies' Phase IIb BLP 25 Liposome vaccine (L-BLP25) trial in patients with Stage IIIb and IV non-small cell lung cancer (NSCLC), showed that patients treated with the novel vaccine survived 4.4 months longer than those who received only standard therapy.

"The 4.4 month increase in median survival in patients receiving L-BLP25 is a notable period of time for such an aggressive disease as non-small cell lung cancer," said Dr. Charles Butts, Medical Oncologist, Cross Cancer Institute, Edmonton, Alberta and lead investigator in the trial. "The data indicate a favourable safety profile and maintenance of quality of life in the vaccine arm, further supporting the plans to evaluate the vaccine in additional clinical trials. More exciting are the results we're seeing in earlier stage patients."

Dr. Butts presented the trial data at the 29th Meeting of the European Society for Medical Oncology (ESMO) being held in Vienna, Austria (October 29- November 2, 2004). His oral presentation, entitled, "A multicenter phase IIb randomized study of liposomal MUC1 vaccine immunotherapy of non-small cell lung cancer (NSCLC); L-BLP25 Non-Small Cell Lung Cancer Study Group," was part of the Presidential Symposium today and also was included in ESMO's press conference highlighting significant developments in oncology, held yesterday.

All patients were required to have stage IIIB or IV NSCLC that was stable or had responded following treatment with first line chemotherapy, or combined chemotherapy with radiation therapy, prior to randomization into the study. Patients were randomized equally to the treatment arm (vaccine plus best supportive care) or to the control arm (best supportive care alone). Best supportive care could consist of second line chemotherapy, palliative radiotherapy, or other treatments as determined by the investigator. The primary endpoints were survival and safety, with quality of life as a secondary endpoint. Survival was calculated from the date of randomization in the study to the date of death or last contact.

In the 171-patient study, the Companies observed a median survival benefit of 4.4 months in patients receiving L-BLP25 after having achieved either stable disease or a response to first line chemotherapy. Overall median survival for the treatment group receiving the vaccine (n=88) was 17.4 months versus 13 months for the control group (n=83) (Kaplan-Meier log-rank p=0.0652; Adjusted Cox p=0.1120). In the overall patient population, two-year survival was 43.2 per cent for the treatment group and 28.9 per cent for the control group.

Patients in the vaccine arm maintained their baseline quality of life for a longer period of time than those in the control arm. The difference reached statistical significance at two time points, 19 and 31 weeks.

A subset analysis of locoregional Stage IIIb patients (disease contained within the lung) showed two-year survival to be 36.7 per cent for the control arm (n=30) versus 60 per cent for the treatment arm (n=35) per cent. Median survival was 13.3 months for patients in the control group, while the median survival for the treatment group had not yet been reached, at the time of analysis (Kaplan-Meier log-rank p=0.0575; Adjusted Cox p=0.0692).

"This peer-reviewed setting is an important opportunity for us to make our data available to the global oncology community," said Alex McPherson, MD, PhD, President and CEO of Biomira. "Lung cancer has historically been a very challenging disease to treat. These notable data, along with the potential for the results to further improve at the planned survival update in December, support our enthusiasm for this program."

"These Phase II data are very encouraging in terms of offering a potentially meaningful benefit to patients in an area where so little progress has been realized despite many years of work," said Bernhard Ehmer, MD, Vice President and Head of Merck's Oncology Business Area.

Biomira and Merck KGaA expect to announce an update from this trial in December 2004. The Companies also expect to launch a large trial in unresectable Stage III patients in several countries, including the U.S., Europe and Canada in late 2005.

Additional Study Details

Treated patients received a single low-dose of intravenous cyclophosphamide three days prior to the first vaccination of a 1000 (micro)g dose of L-BLP25. Vaccinations were given weekly for the first eight weeks, and at six-week intervals thereafter. Quality of life and clinical assessments took place at Week 4, Week 8 and then at 12-week intervals for the remainder of the trial.

Mild flu-like symptoms and injection site reactions occurred in approximately half of the patients in the vaccine arm. Other adverse events were consistent with disease status in both arms of the trial.

About Lung Cancer

Lung cancer is the leading cause of cancer-related mortality for men and women in North America. In 2004, approximately 174,000 new cases of lung cancer will be diagnosed in the United States and 160,000 Americans will die from the disease. In Canada, there will be an estimated 21,700 new lung cancer diagnoses and approximately 18,900 Canadians will die from the disease this year. NSCLC accounts for approximately 75 to 80 per cent of all primary lung cancers. At the time of diagnosis, only 25 per cent of NSCLC patients are potentially curable by surgery.

About L-BLP25

L-BLP25 is a synthetic MUC1 peptide vaccine that incorporates a 25-amino acid sequence of the MUC1 cancer mucin, in a liposomal formulation. The liposome enhances recognition of the cancer antigen by the immune system and facilitates better delivery. L-BLP25 is designed to induce an immune response to cancer cells.
