- 5 Year Data Confirm Superiority of Xeloda Over the Mayo Clinic
Regimen in Treating Colon Cancer

Five-year follow-up data from the X-ACT trial presented today at
the 14th European Cancer Conference (ECCO) show that patients with
stage III colon cancer live longer when taking the oral chemotherapy
Xeloda (capecitabine) compared to the injections of bolus 5-FU/FA(i),
the Mayo Clinic regimen. Patients were followed up for a median of 7
years, with results confirming 5 year overall survival rates of 71.4%
in the Xeloda group and 68.4% in the 5-FU/FA group. The trial also
showed that patients taking Xeloda were as likely to be relapse-free
and disease-free at five years as those having bolus i.v. treatment.

"These results are very encouraging, as the data show patients
living longer with Xeloda monotherapy." said Professor Chris Twelves,
University of Leeds and St. James University Hospital, Leeds. "We
have long-term evidence now that clearly supports Xeloda's
superiority over the Mayo Clinic regimen. There is no reason we
should ask colon cancer patients to endure the burdens associated
with bolus i.v. treatment, visiting the clinic 5 consecutive days for
an injection, when there is a highly effective option with fewer
side-effects that patients can take in the comfort of their home."

"This adds to the growing body of evidence supporting the fact
that Xeloda can replace 5-FU in colorectal cancer regimens." Prof
Twelves said.

Earlier results from the X-ACT study show that Xeloda is also more
cost-effective than the Mayo Clinic regimen. Xeloda patients spend
85% less time visiting their doctor or hospital for treatment and for
every 100 patients treated with Xeloda, a doctor could save
approximately one year (400 days) in consultation time compared to
i.v. 5-FU/FA.

Previous studies show that patients prefer oral treatment as it
allows them to carry on their daily lives as normally as
possible(1),(2).

Earlier results also confirm that Xeloda's targeted approach
causes less of the side-effects usually associated with chemotherapy.
Additionally, any side-effects can be easily managed by altering the
dose without compromising efficacy(3),(4). This has a cost-saving
benefit with previous analyses of the X-ACT study showing that costs
for medicines to treat side effects such as nausea, vomiting and
diarrhoea, were cut by nearly 75% in patients taking Xeloda compared
to i.v. 5-FU/FA.

Based on the initial results of the X-ACT study, Xeloda was
approved by the European Medicines Agency (EMEA) and U.S. Food and
Drug Administration (FDA) for adjuvant (post-surgery) treatment of
colon cancer in March and June 2005, respectively. The results seen
in the five-year follow up data with single agent Xeloda are broadly
similar to those previously seen in the Mosaic study with continuous
infusion 5FU/FA and the addition of oxaliplatin.

Earlier this year Roche applied for a label extension in Europe to
broaden the label for Xeloda in the form of Xeloda plus oxaliplatin
(XELOX) with or without Avastin for the treatment of metastatic
(advanced) colorectal cancer.

Colorectal cancer (cancer of the colon and rectum) is the third
most commonly reported cancer worldwide, and it is estimated that
over 50% of people diagnosed with colorectal cancer will die of the
disease.

This year will see 281,700 suffer with adjuvant colon cancer in
the majority of the developed world (UK, Spain, Italy, France,
Germany, Japan, Canada and the USA), and its incidence is likely to
increase, with over 286,500 patients expected in 2008(5).

Chemotherapy following surgery (adjuvant therapy) is one of the
most common treatment approaches in patients diagnosed with the
disease.

Highlights from the new X-ACT data

- Overall Survival -- With a median follow-up of 7 years, the
5-year overall survival rates were 71.4% (95% CI 68-74%) in the
Xeloda group and 68.4% (95% CI 65-71%) in the 5-FU/FA group,
corresponding to a HR of 0.86 (95% CI 0.74-1.01).

- Disease-free Survival (DFS) -- At a median follow-up of 3.8
years, DFS in the Xeloda group was at least equivalent to 5-FU/FA
(intent-to-treat analysis, P

About the X-ACT Study:

The goal of the X-ACT trial (Xeloda in Adjuvant Colon Cancer
Therapy) was to evaluate the safety and efficacy of Xeloda(R)
(capecitabine), a targeted oral chemotherapy, versus the old global
standard of care, bolus intravenous 5-FU/FA (also known as the Mayo
Clinic regimen), in patients who recently have had colon cancer
surgery (adjuvant therapy).

The X-ACT trial randomly assigned 1987 patients with resected
stage III colon cancer to oral capecitabine (n=1004) or bolus 5-FU/FA
(Mayo Clinic regimen; n=983) over 24 weeks. The primary efficacy
endpoint was at least equivalence in disease-free survival (DFS);
other efficacy endpoints included relapse-free survival (RFS) and
overall survival.
