Seattle Genetics Highlights ADCETRIS® (Brentuximab Vedotin) Data in Relapsed Hodgkin Lymphoma and Other CD30-Positive …

ATLANTA--(BUSINESS WIRE)--

Seattle Genetics, Inc. (SGEN) today summarized ADCETRIS (brentuximab vedotin) data in relapsed Hodgkin lymphoma (HL) and other CD30-positive malignancies from multiple presentations at the 54th American Society of Hematology (ASH) Annual Meeting and Exposition being held December 8-11, 2012 in Atlanta, GA. Highlights include compelling survival data from long-term follow up in a pivotal clinical trial of ADCETRIS in relapsed or refractory HL and a retrospective comparison of overall survival among patients treated with ADCETRIS to those not treated with ADCETRIS following an autologous stem cell transplant (ASCT). In addition, data describe the activity and tolerability of ADCETRIS in the salvage HL setting from an investigator-sponsored trial and in relapsed patients age 60 or over with CD30-positive malignancies, including HL. ADCETRIS is an antibody-drug conjugate (ADC) directed to CD30, a defining marker of classical HL.

"There are more than a dozen data presentations at ASH evaluating the use of ADCETRIS in CD30-positive malignancies and we are very encouraged by both the broad application across multiple hematologic disease areas as well as the encouraging activity associated with ADCETRIS, said Clay B. Siegall, Ph.D., President and Chief Executive Officer of Seattle Genetics. The extensive investigator and corporate data presentations at ASH clearly demonstrate the important role ADCETRIS plays in the treatment of relapsed HL and systemic anaplastic large cell lymphoma and the promise of the role it potentially will play in additional future indications.

Long-term Survival Analysis of an Ongoing Phase 2 Study of Brentuximab Vedotin in Patients with Relapsed or Refractory Hodgkin Lymphoma (Abstract #3689)

A pivotal, single-arm trial was conducted in 102 relapsed or refractory HL patients after ASCT to assess efficacy and safety of single-agent ADCETRIS. In addition, the trial was designed to determine duration of response, progression-free survival and overall survival. Enrolled patients had received a median of more than three prior chemotherapy regimens.

Data highlights from the long-term survival analysis in the pivotal trial were:

Overall Survival Benefit for Patients with Relapsed Hodgkin Lymphoma Treated with Brentuximab Vedotin After Autologous Stem Cell Transplant (Abstract #3701)

An independent retrospective comparison conducted by MD Anderson Cancer Center evaluated overall survival in 102 relapsed HL patients treated with ADCETRIS in a pivotal clinical trial compared to data from 756 relapsed HL patients treated at six international centers (Horning et al., 2008). The authors compared median overall survival, starting at the time of receiving an ASCT, among ADCETRIS treated patients to patients not treated with ADCETRIS. Key findings, which were highlighted in a presentation by Dr. Meghan Karuturi from MD Anderson Cancer Center, included:

Brentuximab Vedotin as a First Line Salvage Therapy in Relapsed/Refractory HL (Abstract #3699)

An investigator-sponsored trial was conducted to evaluate ADCETRIS as a salvage therapy for HL. Fourteen patients were evaluated for response and safety and all had relapsed or refractory HL after initial therapy with the chemotherapy regimens ABVD (Adriamycin, bleomycin, vinblastine, dacarbazine) or BEACOPP (bleomycin, etoposide, Adriamycin, cyclophosphamide, Oncovin, procarbazine hydrochloride, prednisone) or a combination of chemotherapy with or without consolidative radiation treatment. Patients were treated with ADCETRIS every three weeks for a maximum of four cycles. Data were presented by Dr. Robert Chen from City of Hope National Medical Center in Duarte, CA.
