ATLANTA--(BUSINESS WIRE)--

Seattle Genetics, Inc. (SGEN) today announced that results from two ongoing investigator-sponsored phase II clinical trials of ADCETRIS (brentuximab vedotin) in patients with relapsed cutaneous T-cell lymphoma (CTCL) were presented at the 54th American Society of Hematology (ASH) Annual Meeting and Exposition being held December 8-11, 2012 in Atlanta, GA. ADCETRIS is an antibody-drug conjugate (ADC) directed to CD30. ADCETRIS has not been approved for use in the treatment of CTCL.

Brentuximab Vedotin Demonstrates Significant Clinical Activity in Relapsed or Refractory Mycosis Fungoides with Variable CD30 Expression (Abstract #797)

The ongoing phase II clinical trial is enrolling CTCL patients with mycosis fungoides (MF) or Sezary syndrome. Twenty patients have been enrolled to date with a median of six prior systemic therapies. The primary endpoint of the trial is clinical response rate. Secondary endpoints include correlation of clinical response with CD30 expression levels, duration of response and safety. The study was led by principle investigator Dr. Youn H. Kim from Stanford University School of Medicine in Stanford, CA, and was presented in an oral session. Key findings include:

Results of a Phase II Trial of Brentuximab Vedotin (SGN-35) for CD30+ Cutaneous T-Cell Lymphomas and Lymphoproliferative Disorders (Abstract #3688)

Data were presented from a phase II investigator-sponsored trial evaluating the use of ADCETRIS in CD30-positive CTCL patients, including lymphomatoid papulosis (LyP), primary cutaneous anaplastic large cell lymphoma (pcALCL) or MF. The ongoing study is being conducted by Dr. Madeleine Duvic from The University of Texas MD Anderson Cancer Center in Houston, TX. Among 54 patients enrolled to date, 46 patients were evaluable at the time of analysis. The primary endpoint of the trial is to evaluate the safety and efficacy of ADCETRIS in CD30-positive CTCL. The key findings include:

Seattle Genetics and Millennium: The Takeda Oncology Company have initiated the ALCANZA trial, a randomized phase III clinical trial of ADCETRIS for relapsed CD30-positive CTCL patients. The trial is assessing ADCETRIS versus investigators choice of methotrexate or bexarotene in patients with CD30-positive CTCL, including those with pcALCL or MF. The primary endpoint of the study is overall response rate lasting at least four months. Approximately 124 patients will be enrolled in the pivotal trial. The ALCANZA trial is being conducted under a Special Protocol Assessment agreement from the U.S. Food and Drug Administration (FDA). The study also received European Medicines Agency scientific advice.

About CTCL

Lymphoma is a general term for a group of cancers that originate in the lymphatic system. There are two major categories of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma. Cutaneous lymphomas are a category of non-Hodgkin lymphomas that primarily involve the skin. According to the Cutaneous Lymphoma Foundation, CTCL is the most common type of cutaneous lymphoma and typically presents with red, scaly patches or thickened plaques of skin that often mimic eczema or chronic dermatitis. Progression from limited skin involvement is variable and may be accompanied by tumor formation, ulceration and exfoliation, complicated by itching and infections. Advanced stages are defined by involvement of lymph nodes, peripheral blood and internal organs. According to published literature, up to 50 percent of CTCL patients lesions express CD30.
