PRIMARY OBJECTIVE:
I. To assess the event free survival (EFS) of a novel regimen incorporating brentuximab
vedotin (Bv; Adcetris) in the chemotherapy backbone of doxorubicin hydrochloride
(doxorubicin) (Adriamycin), vincristine sulfate (vincristine), etoposide, prednisone and
cyclophosphamide (Bv-AVEPC) in newly diagnosed high-risk classical Hodgkin lymphoma (cHL)
compared to those treated with Adriamycin, bleomycin sulfate, vincristine sulfate,
etoposide, prednisone, and cyclophosphamide (ABVE-PC).
SECONDARY OBJECTIVES:
I. To determine whether children/young adults with high-risk cHL treated with Bv-AVEPC
have a higher rate of early response (determined by fludeoxyglucose F 18 [FDG]-positron
emission tomography [PET]) and a reduction in protocol directed radiation therapy (RT)
compared to those treated with ABVE-PC.
II. To compare the rate of neuropathy (>= grade 3) among patients treated on the Bv-AVEPC
(experimental arm) to patients treated on the ABVE-PC (standard arm).
EXPLORATORY OBJECTIVES:
I. To validate and compare the Childhood Hodgkin International Prognostic Score (CHIPS)
to conventional Ann Arbor stage (stages II B with bulk, III B, IV A or B) in predicting
outcome in high-risk childhood cHL.
II. To determine the incidence of preferentially expressed antigen in melanoma (PRAME)
and testis-specific antigens in Epstein-Barr virus (EBV)- cHL tumors and the incidence of
EBV antigens (Epstein-Barr nuclear antigen 1 [EBNA1], Epstein-Barr virus latent membrane
protein 1 [LMP1], large multifunctional peptidase 2 [LMP2]) in EBV+ cHL tumors, with the
goal of developing strategies to integrate cellular therapy into treatment for newly
diagnosed high-risk cHL. (Biology) III. To incorporate qualitative visual FDG-PET into
response-directed treatment algorithms and explore quantitative FDG-PET and computed
tomography (CT) definitions of tumor burden and response for incorporation into next
generation pediatric cHL risk-stratification schemes, exploring the extension of these
algorithms to young adults. (Imaging) IV. To evaluate the reduction in normal tissue
irradiation associated with the current treatment approach compared to the volume of
historic involved field radiation therapy (IFRT) fields. (Radiation Therapy) V. To
evaluate EFS and patterns of relapse following protocol-specified RT utilization and
treatment volumes. (Radiation Therapy) VI. To characterize the extent of chemotherapy
induced peripheral neuropathy (CIPN), as reported by patients and parent proxies, through
serial administration of the Functional Assessment of Cancer Therapy-Gynecologic Oncology
Group-Neurotoxicity (FACT-GOG-NTX). (Patient Reported Outcomes [PRO] of Peripheral
Neuropathy and Health-Related Quality of Life) VII. To describe the Health-Related
Quality of Life (HRQL) consequences of peripheral neuropathy over time by correlating
total neuropathy scale scores with the individual items with the Child Health Ratings
Inventories (CHRIs)-Global scale (e.g., physical health, pain, emotional functioning).
(PRO of Peripheral Neuropathy and Health-Related Quality of Life) VIII. To perform a
cross validation of the FACT-GOG-NTX with the Total Neuropathy Score-Pediatric
Vincristine (TNS-PV) to determine the performance of both measures with the use of
brentuximab vedotin in a limited institutional approach in children and adolescents with
cHL. (PRO of Peripheral Neuropathy and Health-Related Quality of Life) IX. To assess the
resource use and cost implications of Bv in combination with chemotherapy and
radiotherapy (RT) for newly diagnosed high-risk cHL in children and young adults.
(Economic) X. To estimate the risk of relapse among rapidly responding lesions (RRL)
subjects that have at least one lesion that is Deauville 3 at PET 2. (Follow-up of
Deauville score 3 lesions on FDG-PET imaging [confirmed by central imaging review]) XI.
To characterize the pharmacokinetics of brentuximab vedotin in children < 13 years of
age.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I (ABVE-PC): Patients receive doxorubicin hydrochloride intravenously (IV) over on
days 1-2, bleomycin sulfate IV or subcutaneously (SC) on days 1 and 8, vincristine
sulfate IV on days 1 and 8, etoposide IV on days 1-3, prednisone orally (PO) twice daily
(BID) or methylprednisolone IV on days 1-7, and cyclophosphamide IV on days 1 and 2.
ARM II (Bv-AVEPC): Patients receive brentuximab vedotin IV on day 1. Patients also
receive doxorubicin hydrochloride, etoposide, prednisone or methylprednisolone, and
cyclophosphamide as in Arm I and vincristine sulfate IV on day 8.
In both arms, treatment repeats every 21 days for 5 cycles in the absence of disease
progression or unacceptable toxicity. Granulocyte simulating factor (GCSF) or equivalent
is given on both arms.
After completion of study treatment, patients are followed up at 3, 6, 9, 12, 18, 24, 30,
36, and 48 months.
