Breast cancer drug Herceptin has been approved in Europe for use with hormonal therapy for postmenopausal patients with HER2 and hormone receptor positive metastatic disease.

Herceptin, made by Swiss drugmaker Roche Holding AG, is already approved in Europe for early and metastatic HER2-positive breast cancer.

This new approval is based on data from an international late stage clinical trial showing the combination of Herceptin with hormonal therapy doubled the median progression-free survival time.

ImClone Systems Inc.'s drug Erbitux has failed to help pancreatic cancer patients live longer. It's also failed to grow ImClone's market -- not surprising since it's the company's only drug.

Imclone, partnering with Bristol-Myers Squibb Co., wanted to see Erbitux -- already cleared for use with colon, head, and neck cancers -- extend the lives of patients with cancer marked by a spread to the pancreas.

No one is giving up just yet, and Imclone plans additional tests on Erbitux's use in pancreatic cancer. A study using a combination of Erbitux and Avastin and chemotherapy is up next.

"There are reasons to think Erbitux works in pancreatic cancer, but the current results are not as dramatic as we hoped," said Alex Denner, lead for an executive committee that manages ImClone. "We remain committed to evaluating Erbitux in pancreatic cancer."

If approved, Erbitux will compete with Tarceva, sold by Roche Holding AG, Genentech Inc., and OSI Pharmaceuticals Inc. as a treatment for pancreatic and lung cancers.

About 37,170 new cases of pancreatic cancer are expected to occur in 2007 in the United States. And 33,370 people will die from the disease, according to the American Cancer Society. Pancreatic cancer is one of the most aggressive cancers, and there is no screening option that works at catching the disease in its early stages.

Only about 5 percent of patients with pancreatic cancer are still alive five years after being diagnosed.

The latest Phase III study of Roche's cancer treatment Xeloda -- featuring 627 previously treated colorectal patients -- has reached its primary endpoint of progression-free survival.

Study results show that the chemotherapy combination XELOX (Xeloda plus oxaliplatin) was as effective as the combination FOLFOX-4 (infused 5-FU/leucovorin plus oxaliplatin) in delaying disease progression -- a result that will be used in worldwide submissions of the drug.

Xeloda, an oral chemotherapy agent that can be taken at home, is already used in previously untreated colorectal cancer patients. It has also been approved for treatment of early stage colon cancer and for breast cancer that has spread to other parts of the body.
