Brentuximab Vedotin and Combination Chemotherapy in Treating Patients With CD30-Positive Peripheral T-cell Lymphoma

PRIMARY OBJECTIVES:

I. Assess the safety and tolerability of cyclophosphamide, doxorubicin, etoposide,
prednisone, and brentuximab vedotin (CHEP-BV), as induction therapy in patients with
CD30-positive peripheral T-cell lymphoma (PTCL). (Safety lead-in) II. Assess the
anti-lymphoma activity of CHEP-BV as induction treatment in patients with CD30-positive PTCL.
(Phase 2)

SECONDARY OBJECTIVES:

I. Describe outcomes of CD30-positive PTCL patients who go on to receive BV consolidation
therapy post CHEP-BV induction with/without autologous hematopoietic cell
transplantation/radiation.

TERTIARY OBJECTIVES:

I. Explore the rate of minimal residual disease (MRD) negativity (as assessed by
next-generation sequencing) and MRD kinetics after CHEP-BV and BV consolidation therapy in
CD30-positive PTCL.

II. Explore the possible association between outcome after study treatment and CD30
expression, gene expression profiles (GEP), and genetic mutations as measured in PTCL tumor
samples.

OUTLINE:

INDUCTION: Patients receive cyclophosphamide intravenously (IV) and doxorubicin IV on day 1,
etoposide IV on days 1-3, and prednisone orally (PO) on days 1-5. Patients also receive
brentuximab vedotin IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 6
courses in the absence of disease progression or unacceptable toxicity.

CONSOLIDATION: Between 30-60 days post-consolidative autologous stem cell therapy or after
completing induction course 6, patients with objective response (compete response or partial
response) receive brentuximab vedotin IV over 30 minutes on day 1. Treatment repeats every 21
days for up to 10 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, 6 months and 12
months.

the urine test is positive or cannot be confirmed as negative, a serum pregnancy test
will be required

- Agreement by WOCBP and males of childbearing potential to use an effective method of
birth control or abstain from heterosexual activity for the course of the study
through at least 6 months after the last dose of protocol therapy; childbearing
potential defined as not being surgically sterilized (men and women) or have not been
