Takeda and Seattle Genetics Highlight Post-Hoc Analysis Examining Progression-free Survival with ADCETRIS® …

LUGANO, Switzerland--(BUSINESS WIRE)--

Takeda Pharmaceutical Company Limited (TSE:4502) and Seattle Genetics, Inc. (SGEN) today announced data from a post-hoc analysis examining progression-free survival (PFS) following treatment with ADCETRIS (brentuximab vedotin) versus last prior therapy in patients diagnosed with relapsed or refractory Hodgkin lymphoma (HL) post-autologous stem cell transplant (ASCT) or relapsed or refractory systemic anaplastic large cell lymphoma (sALCL). The data were highlighted during a presentation at the 12th International Conference on Malignant Lymphoma (ICML) being held June 1922, 2013 in Lugano, Switzerland.

ADCETRIS is an antibody-drug conjugate (ADC) directed to CD30, a defining marker of classical HL and sALCL.

The post-hoc analysis compared investigator assessed PFS following ADCETRIS single-agent treatment to the last prior systemic therapy in patients taking part in two pivotal Phase 2 studies. The post-hoc analysis was conducted in patients with relapsed or refractory HL post-ASCT or relapsed or refractory sALCL in the intent-to-treat (ITT) population. It also included prior systemic treatment histories and post-ADCETRIS stem cell transplant experience for each patient in the ITT populations.

These encouraging data suggest that ADCETRIS may delay disease progression compared to prior therapies used in this heavily pretreated patient population, said John Radford, M.D., Professor of Medical Oncology, University of Manchester, Manchester, UK. ADCETRIS is a CD30-targeted treatment option for patients with relapsed or refractory HL or relapsed or refractory sALCL that has shown a high overall response rate, including durable complete responses in both of its approved indications.
