`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

`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.

`Roche/Genentech's breakthrough T­DM1 wins blockbuster OK for breast cancer ­ FierceBiotech
`to match T­DM1's targeting capabilities with a powerful drug payload. 
`Effective content harmonization
`requires a global system that can
`balance the needs of both the
`corporate office and satellite entities and
`partners. For companies considering content
`harmonization initiatives, this paper discusses
`best practices and the efficiency benefits they

`"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."
