The European Commission (EC) has extended the current conditional marketing authorization of brentuximab vedotin (Adcetris) to include the treatment of adults with CD30+ Hodgkin lymphoma (HL) who are at an increased risk of relapse or progression following autologous stem cell transplant (ASCT).
Conditional marketing authorizations are valid for 1 year and are reviewed annually.
The company developing the drug is required to provide comprehensive data confirming the drug’s benefit-risk balance is positive. Once these data are available, the marketing authorization may be converted into a standard marketing authorization.
Drugs are eligible for conditional marketing authorization if they are designated as orphan medicines, intended for use in emergency situations, or designed to treat, prevent, or diagnose seriously debilitating or life-threatening diseases.
The EC previously granted brentuximab vedotin conditional marketing authorization for 2 indications:
- To treat adults with relapsed or refractory CD30+ HL after ASCT or following at least 2 prior therapies when ASCT or multi-agent chemotherapy is not a treatment option
- To treat adults with relapsed or refractory systemic anaplastic large-cell lymphoma (sALCL).
In January 2016, the EC approved a Type II variation to include data on the retreatment of adult patients with HL or sALCL who previously responded to brentuximab vedotin and later relapsed.
Brentuximab vedotin is under joint development by Seattle Genetics and Takeda Pharmaceutical Company Limited.
AETHERA trial
The EC’s decision to extend the conditional marketing authorization of brentuximab vedotin is based on results from the phase 3 AETHERA trial.
The trial was designed to compare brentuximab vedotin to placebo, both administered for up to 16 cycles (approximately 1 year) every 3 weeks following ASCT. Results from the trial were published in The Lancet in March 2015 and presented at the 2014 ASH Annual Meeting.
The study enrolled 329 HL patients at risk of relapse or progression, including 165 on the brentuximab vedotin arm and 164 on the placebo arm.
Patients were eligible for enrollment if they had a history of primary refractory HL, relapsed within a year of receiving frontline chemotherapy, and/or had disease outside of the lymph nodes at the time of pre-ASCT relapse.
Brentuximab vedotin conferred a significant increase in progression-free survival over placebo, with a hazard ratio of 0.57 (P=0.001). The median progression-free survival was 43 months for patients who received brentuximab vedotin and 24 months for those who received placebo.
The most common adverse events (≥20%), of any grade and regardless of causality, in the brentuximab vedotin arm were neutropenia (78%), peripheral sensory neuropathy (56%), thrombocytopenia (41%), anemia (27%), upper respiratory tract infection (26%), fatigue (24%), peripheral motor neuropathy (23%), nausea (22%), cough (21%), and diarrhea (20%).
The most common adverse events (≥20%), of any grade and regardless of causality, in the placebo arm were neutropenia (34%), upper respiratory tract infection (23%), and thrombocytopenia (20%).
In all, 67% of patients on the brentuximab vedotin arm experienced peripheral neuropathy. Of those patients, 85% had resolution (59%) or partial improvement (26%) in symptoms at the time of their last evaluation, with a median time to improvement of 23 weeks (range, 0.1-138).
