`
`Roche ($RHHBY) will market the newly approved drug as
`Kadcyla. Its partner ImmunoGen ($IMGN) stepped up with the
`ADC technology and stands to gain a small, singledigit royalty
`stream from the therapy.
`
`The drug will cost $9,800 a month,or about $94,000 for a 9.5
`month course of therapy. Analysts' peak sales projections for
`this drug have ranged from $2 billion to $5 billion a year.

`"Kadcyla is an antibodydrug conjugate representing a completely new way to treat
`HER2positive metastatic breast cancer, and it helped people in the EMILIA study
`live nearly six months longer," said Hal Barron, Roche's chief medical officer and
`head of global product development.

`
`In early October Roche revealed that the armed antibody delivered a 32% reduction
`in the risk of death among patients in the pivotal Phase III study when compared to
`the standardofcare arm. The median overall survival rate for TDM1 patients hit
`an impressive 30.9 months, while patients taking a combination of Tykerb and
`Xeloda achieved a 25.1month OS rate.

`"Kadcyla delivers the drug to the cancer site to shrink the tumor, slow disease
`progression and prolong survival," said Dr. Richard Pazdur, director of the Office of
`Hematology and Oncology Products in the FDA's Center for Drug Evaluation and
`Research. "It is the fourth approved drug that targets the HER2 protein."
`
`Fewer people who received Kadcyla experienced severe side effects compared to
`those receiving standard therapy (40.8 percent vs. 57.0 percent), the FDA noted.
`But as expected a boxed warning will apply,noting that the drug can cause liver
`toxicity, heart toxicity and death. "The drug can also cause severe lifethreatening
`birth defects, and pregnancy status should be verified prior to starting Kadcyla
`treatment."
`
`"The biggest news in today's press release, given that approval was expected, was
`that the label allows for use in frontline HER2 positive metastatic breast cancer,"
`says Cowen's Simos Simeonidis in a note this morning. "This was not a major
`surprise, since EMILIA included about 12% frontline mBC patients (about 60 1st
`line mBC patients in the TDM1 arm of the EMILIA trial), but it was definitely not a
`given."
