Xeloda in combination with oxaliplatin shown to be effective in early colon cancer

RocheRoche has announced results from the international phase III study NO16968 (XELOXA), investigating oral Xeloda in combination with intravenous oxaliplatin (XELOX) immediately after surgery, which show that patients with colon cancer taking XELOX live disease free for longer compared to those taking the commonly used intravenous chemotherapy combination 5-fluorouracil/leucovorin (5-FU/LV). The data prove that XELOX is superior to 5-FU/LV in terms of the time patients live without their cancer being detectable.

The trial, conducted in previously untreated patients who have undergone surgery for colon cancer, studied use of XELOX for 24 weeks. Patients in the XELOX group demonstrated significantly better disease-free survival compared to patients receiving 5-FU/LV.

"While Xeloda is already approved for the treatment of early-stage colon cancer as monotherapy, the results of this study mean that physicians will now be able to offer their patients Xeloda as a combination chemotherapy. This is an important development for patients as colon cancer, if caught early enough, can be cured, so physicians need a wide range of treatment options," said William M. Burns, CEO of Roche's Pharmaceuticals Division.

Data from the trial will be submitted for presentation at upcoming international scientific meetings. Roche plans to file the data with health authorities to extend the current label for Xeloda.

Xeloda is a highly effective oral chemotherapy drug that can be used alone, or in combination with other drugs, for the treatment of colorectal (including colon), stomach and breast cancer. It is already approved for the treatment of colon cancer after surgery in the US, EU, Japan and rest of the world.

Colorectal cancer is the second most common cause of death from cancer across all cancer types in men and women in Europe(1) and is the third most commonly reported cancer in the world, with nearly one million cases occurring annually(2). Colon cancer refers to cancer of the large intestine (colon), which is the lower part of the digestive system, while rectal cancer specifies cancer of the last segment of the colon. Together, they're often referred to as colorectal cancer.

About the study
The NO16968 trial (XELOXA) is an open-label, randomised, phase III study of XELOX (oral Xeloda in combination with intravenous oxaliplatin) versus 5-fluorouracil/leucovorin (5-FU/LV) as adjuvant therapy for patients with stage III colon cancer who have undergone surgery. The study included 1886 patients and was conducted at 240 study sites across 29 countries. The primary endpoint of the study was to demonstrate the superiority of XELOX versus 5-FU/LV in terms of disease-free survival. Secondary endpoints included overall survival, safety profiles and perceived treatment convenience between the treatment arms.

About Xeloda (capecitabine)
Xeloda is a highly effective targeted oral chemotherapy offering patients a survival advantage when taken on its own or in combination with other anticancer drugs. Xeloda is converted to the active cancer-killing agent 5-FU (5-fluorouracil) directly inside the cancer cells, thus reducing damage to healthy cells. Xeloda tablets can be taken by patients in their own home, reducing the number of hospital visits.

Licensed and marketed by Roche in more than 100 countries worldwide, Xeloda has more than ten years of proven clinical experience providing an effective and flexible treatment option to over 1.8 million people with cancer. Xeloda is currently approved in:
