First pre-surgical breast cancer drug

WASHINGTON — A biotech drug from Roche has become the first medicine approved to treat breast cancer before surgery, offering an earlier approach against one of the deadliest forms of the disease.

The Food and Drug Administration approved Perjeta for women with a form of early-stage breast cancer who face a high risk of having their cancer spread to other parts of the body.

Surgery to remove tumors is usually the first step in treating most forms of cancer. Perjeta is the first drug to be approved as a pre-surgical step.

Doctors hope that using cancer drugs earlier could help shrink tumors, making them easier to remove. In some cases, that could allow women to keep their breasts, rather than having a full mastectomy. Doctors also say that treating the disease at its earliest stages could prevent tumors from returning later, though studies have not yet established that benefit.

“By making effective therapies available to high-risk patients in the earliest disease setting, we may delay or prevent cancer recurrences,” said FDA’s Dr. Richard Pazdur, who directs the agency’s office of cancer products.

Cancer specialists already use several chemotherapy drugs as initial treatments for cancer, but they are not formally approved for the use. The FDA originally approved Perjeta to treat breast cancer that has spread to other parts of the body after surgery.

The FDA granted the drug accelerated approval for its new use based on a study showing women who received the drug as an initial treatment were more likely to be cancer-free 12 weeks later than women who received older drug combinations. Accelerated approval is reserved for drugs that show groundbreaking results for treating life-threatening diseases in early studies.

As a condition of approval, Roche’s Genentech unit must conduct a larger follow-up study showing the drug’s long-term benefits for patients. Generally that means showing that patients lived longer or had a higher quality of life due to taking the drug. Genentech, based in South San Francisco, Calif., has already enrolled about 4,800 patients in the follow-up study, with results expected in 2016.

  • Amid Russian warning, Ukraine's in a security bind

    Russian Foreign Minister Sergey Lavrov warned that Russia would mount a firm response if its citizens or interests come under attack in Ukraine. Although he did not specifically say Russia would launch a military attack, his comments bolstered wide concern that Russia could use any violence in eastern Ukraine as a pretext for sending in troops.
