Seattle Genetics Announces Initiation of Phase II Trial of ADCETRIS

Seattle Genetics

today announced the initiation of a phase II clinical trial evaluating ADCETRIS (brentuximab vedotin) as a front-line therapy for patients age 60 or older with newly diagnosed Hodgkin lymphoma (HL). The trial is designed to assess the efficacy and tolerability of ADCETRIS as a monotherapy for older HL patients who have received no prior treatment. Seattle Genetics is the leader in the field of antibody-drug conjugates (ADCs) and ADCETRIS is an ADC directed to CD30 for relapsed HL and systemic anaplastic large cell lymphoma (sALCL). “The current standard of care for the treatment of front-line HL is a combination of multiple chemotherapeutic agents and has not changed in more than three decades. Some older HL patients are not able to tolerate the significant side effects associated with these regimens, and there is a significant need to identify effective and tolerable treatment options for these patients,” said Thomas C. Reynolds, M.D., Ph.D., Chief Medical Officer at Seattle Genetics. “We believe the response rate associated with single-agent use of ADCETRIS in the relapsed HL setting supports the evaluation of single-agent ADCETRIS in older patients who have received no prior therapy.” The phase II single-arm, open-label clinical trial will evaluate the efficacy and tolerability of ADCETRIS as front-line monotherapy in patients age 60 or older with HL. The trial is enrolling patients who are newly diagnosed and have received no prior HL treatment. The primary endpoint of the trial is to assess the objective response rate (ORR), with key secondary endpoints of safety and tolerability, duration of response, complete remission (CR) rate and progression-free survival (PFS). The study is expected to enroll up to 20 patients at multiple centers in the United States.
