ImmunoGen, Inc. Announces Approval of Roche’s Kadcyla(R) in the European Union

European Commission has approved Kadcyla® for marketing in the EU, which triggers a $5 million milestone payment to ImmunoGen.

Kadcyla comprises Roche’s trastuzumab antibody with ImmunoGen’s linker and DM1 cell-killing agent

WALTHAM, Mass.--(Healthcare Sales & Marketing Network)--ImmunoGen, Inc. (IMGN), a biotechnology company that develops novel anticancer therapeutics using its antibody-drug conjugate (ADC) technology, today announced that the European Commission has granted marketing approval for Kadcyla (trastuzumab emtansine; ado-trastuzumab emtansine in the US) in the European Union (EU). This event triggers a $5 million milestone payment to ImmunoGen.

Kadcyla has been approved for the treatment of adult patients with HER2-positive, unresectable locally advanced or metastatic breast cancer who previously received Herceptin® (trastuzumab) and a taxane, separately or in combination. Patients should have either: (1) received prior therapy for locally advanced or metastatic disease or (2) developed disease recurrence during or within six months of completing adjuvant therapy.

As with the Kadcyla approvals that have been granted in the US, Japan, and other geographies, the approval in the EU is based on the findings in the EMILIA Phase III trial. In the EU and other international markets, the timing of the commercial availability of Kadcyla after approval can vary due to national differences in processes for establishing pricing/reimbursement, with some countries – including Germany – able to launch shortly after approval.

“The European Commission’s decision is an important step toward Kadcyla becoming commercially available across the EU for patients with advanced HER2-positive breast cancer,” commented Daniel Junius, ImmunoGen President and CEO.
