Adcetris is an antibody-drug conjugate (ADC) directed to CD30, a determining marker of Hodgkin lymphoma.
The ADC includes an anti-CD30 monoclonal antibody attached by a protease-cleavable linker to a microtubule disrupting agent, monomethyl auristatin E (MMAE).
Adcetris is being assessed in around 70 clinical studies, including four phase 3 studies.
The FDA has granted the status based on data from the phase 3 ECHELON-1 clinical study, which assessed a combination of Adcetris plus AVD (Adriamycin, vinblastine, dacarbazine) compared to a recognized standard of care chemotherapy regimen in previously untreated advanced classical Hodgkin lymphoma.
According to the company, the trial reached its primary endpoint of a statistically significant improvement in modified progression-free survival (PFS) of the Adcetris containing regimen versus the control arm as assessed by an independent review facility.

Seattle Genetics, along with Takeda, is developing Adcetris. As part of the deal, Seattle Genetics will have commercialization rights in the US and Canada, while Takeda will commercialize the drug in other parts of the world.
Seattle Genetics president and CEO Dr Clay Siegall said: “The phase 3 ECHELON-1 study that supports the Breakthrough Therapy Designation for Adcetris in combination with chemotherapy showed superior activity versus the standard of care chemotherapy regimen in the treatment of frontline advanced classical Hodgkin lymphoma patients.”
