PRIMARY OBJECTIVES:
I. To compare the progression-free survival (PFS) of a standard chemotherapy approach
versus an immunotherapy (IO) approach (brentuximab vedotin and nivolumab) in patients
with newly diagnosed early stage classic Hodgkin lymphoma (cHL) who have a rapid early
response (RER) as determined by position emission tomography post cycle 2 (PET2) after 2
cycles of doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy.
II. To compare the PFS of a standard chemotherapy approach versus an IO therapy approach
(brentuximab vedotin and nivolumab) plus involved site radiation therapy (ISRT) in
patients with newly diagnosed early stage cHL who have a slow early response (SER) as
determined by PET2 after 2 cycles of ABVD chemotherapy.
SECONDARY OBJECTIVES:
I. To demonstrate non-inferiority of overall survival (OS) at 12 years of IO therapy
versus standard therapy in early stage cHL patients who have a RER as determined by PET2
after 2 cycles of doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy.
II. To evaluate the overall survival (OS) at 12 years of IO therapy versus standard
therapy in early stage cHL patients who have a SER as determined by PET2 after 2 cycles
of doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy.
III. To demonstrate non-inferiority of overall survival (OS) at 12 years of IO therapy
versus standard therapy in early stage cHL patients.
IV. To evaluate in patients with newly diagnosed early stage cHL the PFS of a standard
chemotherapy approach versus an IO therapy approach (brentuximab vedotin and nivolumab)
in the overall cohort, in the favorable risk cohort, and in the unfavorable risk cohort.
V. To evaluate the event-free survival (EFS) at 12 years of patients undergoing standard
chemotherapy versus an IO therapy approach (brentuximab vedotin and nivolumab).
VI. To compare the physician-reported treatment-related adverse event (AE) rates between
a standard chemotherapy approach and an IO therapy approach (brentuximab vedotin and
nivolumab) in patients with newly diagnosed early stage cHL.
VII. To compare patient-reported adverse events using pediatric and adult versions of
Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events
(PRO-CTCAE), stratified by age groups, therapeutic arms, and receipt of radiation therapy
(RT) over time.
VIII. To evaluate changes in patient-reported fatigue, cognitive functioning, and
health-related quality of life (HRQoL), e.g., emotional, physical, and role functioning,
by treatment arm, using validated adult and pediatric measurement systems.
IX. To evaluate self-reported late morbidities (e.g., cardiovascular, pulmonary and
endocrine) over time for children, adolescents and adults undergoing standard
chemotherapy versus an IO therapy approach (brentuximab vedotin and nivolumab) with and
without RT using measures from the St. Jude Lifetime Cohort Study (SJLIFE).
X. To evaluate fludeoxyglucose F-18 (FDG)-position emission tomography (PET) measurements
of metabolic tumor burden (MTV and total lesion glycolysis [TLG]) at PET at baseline
(PET1) as a predictive marker of PFS.
XI. To evaluate the associations between race/ethnicity and key outcomes including early
response to therapy, PFS and OS.
EXPLORATORY OBJECTIVES:
I. To evaluate the PFS of a standard chemotherapy approach versus an IO therapy approach
(brentuximab vedotin and nivolumab) in patients with newly diagnosed early stage cHL
across different age groups (ages 5-11 years, 12-21 years, 22-39 years, 40-60 years).
II. To bank specimens for future correlative studies. III. To assess concordance and
discordance of rapid central review and local institutional review of FDG PET 5-point
score (5-PS; previously referred to as Deauville score) at baseline PET1, interim PET2
and end of systemic therapy PET-end of systemic therapy (EST) SER.
IV. To assess the association between PFS and the quantitative FDG-PET/computed
tomography (CT) parameters (PET MTV, TLG, delta-standardized uptake value [SUV] and PET
SUV-based quantitative surrogates [qPET] of visual qualitative 5-PS) on measurements by
automated measurements using convolutional neural networks (CNNs) through
artificial-intelligence (AI) machine learning in the entire population.
V. To assess the agreement between quantitative FDG-PET/CT parameters obtained using AI
and those based on measurements by a trained imaging physician.
VI. To compare patient-reported adverse events (via pediatric [Ped]-PRO-CTCAE and
PRO-CTCAE) to provider adverse event reporting.
VII. To evaluate the association between self-reported race/ethnicity and social
determinants of health.
VIII. To evaluate the associations between race/ethnicity and
post-progression/post-relapse overall survival.
IX. To evaluate the completion rates of PRO and health-related quality of life (HRQoL)
contact forms at 1 year off treatment for the first 450 eligible patients.
X. To collect contact information from participants for future re-contact.
OUTLINE: Patients are stratified by risk status (favorable versus unfavorable) and then
all patients receive the ABVD regimen (doxorubicin hydrochloride intravenously [IV] over
3-15 minutes, bleomycin sulfate IV over at least 10 minutes, vinblastine sulfate IV, and
dacarbazine IV over 15-60 minutes) on days 1 and 15 of each treatment cycle. Cycles
repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Patients then undergo FDG-PET/CT or magnetic resonance imaging (MRI) and are identified
as RER or SER.
Patients with a favorable risk status and RER are randomized to Arm A or Arm B. Patients
with a favorable risk status and SER are randomized to Arm C or Arm D. Patients with an
unfavorable risk status and RER are randomized to Arm E or Arm F. Patients with an
unfavorable risk status and SER are randomized to Arm G or Arm H.
ARM A (RER, FAVORABLE): Patients receive ABVD IV for an additional 2 cycles on study.
Each cycle lasts 28 days and ABVD is administered on days 1 and 15 of each cycle in the
absence of disease progression or unacceptable toxicity. Patients also undergo FDG-PET,
PET, PET-CT, PET-MRI, CT, and/or MRI throughout the trial. Patients may also undergo
blood sample collection on trial.
ARM B (RER, FAVORABLE): Patients receive brentuximab vedotin IV over 30 minutes and
