For participants with CD30 positive Mature T-cell lymphomas who have received brentuximab vedotin, cyclophosphamide, doxorubicin, and prednisone (A-CHP) as induction (4 to 6 cycles) and achieved complete response (CR) or chemo-sensitive partial response (PR) and deemed suitable for autologous stem cell transplant (ASCT) as consolidation, the investigators propose to add brentuximab vedotin after ASCT.

There is currently no standard of care treatment to prevent relapse after upfront treatment or ASCT for CD30-positive peripheral T-cell lymphoma's (PTCL)s. An agent that could improve outcomes in this population would be a major contribution to the field and is likely to be practice changing. Therefore, in addition to studying the anti-lymphoma activity of A-CHP as induction therapy, for participants who respond to induction the investigators propose to add brentuximab vedotin consolidation after ASCT in participants treated with consolidative upfront ASCT.

Inclusion Criteria:

• A-CHP for 6 cycles. First cycle may be cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP)- based if already planned and then 5 cycles of A-CHP.

• Performance status of 0-2.

• Participants with CD30 positive mature T- cell lymphomas who have received A-CHP as induction and achieved complete response (CR) or chemo- sensitive partial response (PR) and deemed suitable for ASCT as consolidation.

• Eligible disease types:

  • Anaplastic lymphoma kinase (ALK)- negative systemic Anaplastic large-cell lymphoma (sALCL)
  • Peripheral T-cell lymphoma- not otherwise specified (PTCL-NOS)
  • Angioimmunoblastic T-cell lymphoma (AITL)
  • Adult T-cell leukemia/lymphoma (ATLL; acute and lymphoma types only, must be positive for human T cell leukemia virus 1)
  • Enteropathy-associated T-cell lymphoma (EATL)
  • Hepatosplenic T-cell lymphoma (HSTCL)

• Fluorodeoxyglucose (FDG)-avid disease by positron emission tomography (PET) and measurable disease by Computed tomography (CT), as assessed by the site radiologist.

• Adequate organ function.

Exclusion Criteria:

• Enrolled in any other treatment clinical trial.

• Is breastfeeding.

• Active severe or medically significant or higher viral, bacterial, or fungal infection within 2 weeks prior to the first dose of study treatment.

• Has human immunodeficiency virus (HIV) infection, hepatitis B surface antigen-positive status, or known or suspected active hepatitis C infection.

• Left ventricular ejection fraction (LVEF) less than 45% or symptomatic cardiac disease, or myocardial infarction within the past 6 months.

• Previous treatment with complete cumulative doses of doxorubicin or other anthracyclines.

• Baseline, moderate, peripheral neuropathy or patients with the demyelinating form of Charcot-Marie-Tooth syndrome.

• Post auto or allo stem cell transplant (SCT).

• Cerebral/meningeal disease related to the underlying malignancy.

• History of progressive multifocal leukoencephalopathy (PML).

• Current diagnosis of any of the following:

  • Primary cutaneous CD30-positive T-cell lymphoproliferative disorders and lymphomas. Cutaneous ALCL with tumor spread outside of the skin and to lymph nodes away from the primary site are eligible.
