Over 30 New Studies of Oral Xeloda Featured at the 2008 Gastrointestinal Cancers Symposium

- U.S. Data Highlights Oral Xeloda versus Standard Infusional Chemotherapy in Gastroesophageal and Colorectal Cancers -

NUTLEY, N.J., January 24, 2008 /PRNewswire/ -- Roche announced today that a total of 33 abstracts involving its oral chemotherapy Xeloda(R) have been accepted for presentation at the 2008 Gastrointestinal Cancers Symposium in Orlando, Fla., from Jan. 25 to 27.

Five poster presentations based on U.S. data offer additional knowledge about Xeloda. Two of these U.S. abstracts compare the safety profile and usage patterns of therapy with oral Xeloda to that of intravenous fluorouracil (5-FU) therapy in gastroesophageal cancer. A second pair of U.S. abstracts evaluates the usage patterns and cost of Xeloda-based regimens against those of 5-FU-based regimens in colon and rectal cancer. The fifth U.S. abstract highlights preclinical efficacy and tolerability results of a novel Xeloda regimen (7/7, or 7 days on, 7 days off) using higher daily doses for the treatment of colorectal cancer.

       capecitabine treatment patterns in patients with gastroesophageal

       cancer (GEC) (Presenter: Wasif Saif)

       gastroesophageal cancer (GEC): A claims database analysis of adverse

       events (AEs) (Presenter: Wasif Saif)

       comparison analysis of capecitabine in the treatment of patients with

       colon or rectal cancer (CRC) (Presenter: Edward Chu)

       with colon and rectal cancer (CRC): A claims database analysis of

       treatment (Presenter: Edward Chu)

    -- Jan. 27, 7 to 8 a.m., [Poster No. A29], In vivo activity of traditional

       vs. novel regimens of capecitabine (C) alone and in combination in a

       colorectal cancer xenograft model (Presenter: Kenneth Kolinsky)


Collectively, the findings of these studies highlight the efficacy and safety of oral Xeloda as a potential alternative to 5-FU in gastroesophageal and colorectal cancers and support further clinical testing to examine the efficacy and safety benefits of the 7/7 Xeloda dosing regimen. Global data presentations, including a meta-analysis that compares the overall survival benefit between Xeloda and 5-FU in adjuvant and metastatic settings, provide similar insights.

About Xeloda

Xeloda is the only FDA-approved oral chemotherapy for both metastatic breast cancer and adjuvant and metastatic colorectal cancer. Inactive in pill form, Xeloda is enzymatically activated within the body; when it comes into contact with a naturally occurring protein called thymidine phosphorylase, or TP, Xeloda is transformed into 5-FU, a cytotoxic (cell-killing) drug. Because many cancers have higher levels of TP than does normal tissue, more 5-FU is delivered to the tumor than to other tissue.

A clinically important drug interaction between Xeloda and warfarin has been demonstrated; altered coagulation parameters and/or bleeding and death have been reported. Clinically significant increases in prothrombin time (PT) and INR have been observed within days to months after starting Xeloda, and infrequently within one month of stopping Xeloda. For patients receiving both drugs concomitantly, frequent monitoring of INR or PT is recommended. Age greater than 60 and a diagnosis of cancer independently predispose patients to an increased risk of coagulopathy.

Xeloda is contraindicated in patients who have a known hypersensitivity to 5-fluorouracil, and in patients with known dihydropyrimidine dehydrogenase (DPD) deficiency. Xeloda is contraindicated in patients with severe renal impairment. For patients with moderate renal impairment, dose reduction is required.

The most common adverse events (greater than or equal to 20%) of Xeloda monotherapy were diarrhea, nausea, stomatitis and hand-foot syndrome. As with any cancer therapy, there is a risk of side effects, and these are usually manageable and reversible with dose modification or interruption.
