Brentuximab vendotin plus CHP meets PFS endpoint in ECHELON-2


 

Takeda Pharmaceuticals and Seattle Genetics announced top-line results in the ECHELON-2 phase 3 trial of brentuximab vedotin plus CHP (cyclophosphamide, doxorubicin, prednisone) in the frontline treatment of CD-30 expressing peripheral T-cell lymphoma (PTCL).

The combination achieved statistically significant improvement in progression-free survival (PFS), compared with the control arm of standard chemotherapy alone using cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). The PFS was assessed by an Independent Review Facility (hazard ratio, 0.71; P = .0110).

The combination of brentuximab vedotin plus CHP also outperformed CHOP in overall survival, a secondary endpoint of the trial (hazard ratio, 0.66, P = .0244), according to the drug sponsors.

Full results of ECHELON-2 will be presented in December 2018 at the annual meeting of the American Society of Hematology, according to the announcement from Seattle Genetics and Takeda.
