This is a single-arm, open-label, multicenter, clinical trial to evaluate the efficacy and
safety of Brentuximab Vedotin (BV) as a single agent in relapsed/refractory CD30+ PTCL
BV will be administered as a single IV infusion on Day 1 of each 21-day cycle. Measures of
anti-cancer activity will be assessed using the revised response criteria for malignant
lymphoma (Cheson et al. 2007).
Computed tomography (CT) scans (chest, neck, abdomen, and pelvis) and PET scan will be
performed at baseline and Cycles 3, 8, 12, and 16. Patients will have an End of Treatment
(EOT) assessment 30 ± 7 days after receiving their final dose of study drug. Patients with at
least stable disease will enter short follow up phase till month 24 with radiology assessment
every 6 months and visit every 12 weeks. After month 24 and for all patients with progressive
disease, long-term follow-up assessments (including survival, disease status and next therapy
information) will be performed every 12 weeks until either patient death or study closure,
whichever occurs first.

- Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) < 3 x upper
limit of normal (ULN).

double barrier method or practice true abstinence from sexual intercourse during the
study and for 6 months after the last dose of study drug.
- Male subjects and their female partners of childbearing potential must be willing to
use an appropriate method of contraception or practice true abstinence from sexual
intercourse during the study and for 6 months after the last dose of study drug.
- Diagnosis of CTCL, ALCL, mycosis fungoides or Sezary Syndrome.
