FDA approves Brentuximab vedotin for the treatment of adult patients with primary cutaneous anaplastic large cell lymphoma

On November 9, 2017, the Food and Drug Administration granted regular approval to brentuximab vedotin (ADCETRIS, Seattle Genetics, Inc.) for the treatment of adult patients with primary cutaneous anaplastic large cell lymphoma (pcALCL) or CD30-expressing mycosis fungoides (MF) who have received prior systemic therapy.

Approval was based on a phase 3, randomized, open-label, multicenter clinical trial (ALCANZA) of brentuximab vedotin in patients with MF or pcALCL who had previously received one prior systemic therapy and required systemic treatment. The trial randomized 131 patients (1:1) to receive either brentuximab vedotin or the physician’s choice of methotrexate or bexarotene.

Efficacy was established based on improvement in objective response rate lasting 4 months (ORR4), complete response (CR) rate, and progression-free survival (PFS) assessed by an independent review facility. ALCANZA demonstrated an improvement (p<0.001) in="" orr4="" in="" the="" brentuximab="" vedotin="" arm="" versus="" the="" physician’s="" choice="" arm,="" 56%="" (95%="" ci:="" 44%,="" 68%)="" versus="" 12%="" (95%="" ci="" 4%,="" 21%),="" respectively.="" cr="" rate="" was="" also="" superior="" (p="0.007)" in="" the="" brentuximab="" vedotin="" arm="" versus="" the="" physician’s="" choice="" arm,="" 16%="" (95%="" ci:="" 8%,="" 27%)="" versus="" 2%="" (95%ci:="" 0,="" 8%).="" alcanza="" also="" demonstrated="" improvement="" in="" pfs="" with="" an="" estimated="" hazard="" ratio="" of="" 0.27="" (95%ci="" 0.17,="" 0.43,=""><0.001). the="" median="" pfs="" was="" 17="" months="" in="" the="" brentuximab="" vedotin="" arm="" versus="" 4="" months="" in="" the="" physician’s="" choice="">

The most common adverse reactions occurring in >20% of patients receiving brentuximab vedotin were anemia, peripheral sensory neuropathy, nausea, diarrhea, fatigue, and neutropenia. The most common adverse event leading to discontinuation was peripheral neuropathy.

The recommended dose of brentuximab vedotin is 1.8 mg/kg up to a maximum of 180 mg as an intravenous infusion over 30 minutes every 3 weeks until a maximum of 16 cycles, disease progression, or unacceptable toxicity.
