N2 - Purpose: Brentuximab vedotin, a monoclonal antibody (cAC10) conjugated to monomethyl auristatin E, targets CD30+ receptors. This phase II open-label trial was conducted to evaluate safety and efficacy in CD30+ cutaneous T-cell lymphomas Patients and Methods: Forty-eight patients with CD30+ lymphoproliferative disorders or mycosis fungoides (MF) received an infusion of 1.8 mg/kg every 21 days. Results: Forty-eight evaluable patients (22 women and 26 men; median age, 59.5 years) had an overal response rate of 73% (95% CI, 60% to 86%; 35 of 48 patients) and complete response rate of 35% (95% CI, 22% to 49%; 17 of 48 patients). Fifteen (54%; 95% CI, 31% to 59%) of 28 patients with MF responded, independent of CD30 expression. In patients with MF/Sézary syndrome, the overall response rate was 50% (five of 10 patients) in patients with low CD30 expression (< 10%), 58% (seven of 12 patients) in patients with medium expression (10% to 50%), and 50% (three of six patients) in patients with high expression (≥ 50%). Time to response was 12 weeks (range, 3 to 39 weeks), and duration of response was 32 weeks (range, 3 to 93 weeks). All patients with lymphomatoid papulosis (n = 9) and primary cutaneous anaplastic T-cell lymphomas (n = 2) responded; time to response was 3 weeks (range, 3 to 9 weeks), and median duration of response was 26 weeks (range, 6 to 44 weeks). Soluble baseline CD30 levels were lowest in complete responders (P =.036). Grade 1 to 2 peripheral neuropathy was observed in 65% of patients (95% CI, 52% to 79%; 31 of 48 patients), is still ongoing in 55% of patients (95% CI, 41% to 69%; 17 of 31 patients), and resolved in 45% of patients (95% CI, 31% to 59%; 14 of 31 patients), with a median time to resolution of 41.5 weeks. Grade 3 to 4 events were neutropenia (n = 5), nausea (n = 2), chest pain (n = 2), deep vein thrombosis (n = 1), transaminitis (n = 1), and dehydration (n = 1). Dose reductions to 1.2
