4. ECOG Performance Score ≤ 2
5. Previous systemic anti-cancer therapy must have been discontinued at least 2 weeks prior to treatment.
6. Topical or systemic steroids (equivalent to ≤ 10 mg/day of prednisone) may be considered if dose has been constant and discontinuation may lead to rebound flare in disease, adrenal insufficiency, and/or unnecessary suffering.
7. If HIV+, patient must be on stable anti-retroviral treatment for 12 weeks prior to C1D1, with CD4 count >200 within 7 days prior to C1D1.
8. Females of childbearing potential must be on acceptable form of birth control per institutional standard

Exclusion Criteria:

1. Concurrent use of other systemic anti-cancer agents or treatments for mycosis fungoides/sezary syndrome, or lymphomatoid papulosis.
2. Grade 2 or greater neuropathy
3. Severe renal impairment (CrCL <30 mL/min)

5. Women of reproductive potential† must have a negative Serum ß human chorionic gonadotropin (ß-HCG) pregnancy test within 1 week of C1D1. They should discuss contraception with treating provider.
6. Previous use of brentuximab vedotin (for Cohort 1 ONLY)

7. Receiving systemic therapy for another primary malignancy (other than T-cell lymphoma).

   • Patients with more than one type of lymphoma may be enrolled after discussion with the MSK Principal Investigator.
   • Adjuvant or maintenance therapy to reduce the risk of recurrence of other malignancy (other than T-cell lymphoma) is permissible after discussion with the MSK Principal Investigator.

8. For Cohort 2, patients who previously progressed on the standard 1.8mg/kg dose and schedule of brentuximab vedotin are ineligible.
