Brief summary

The purpose of this study is to determine whether nivolumab plus brentuximab vedotin (followed by brentuximab vedotin plus bendamustine in patient with suboptimal response) is safe and effective in treating patients with Hodgkin's lymphoma (cHL). Eligible patients are children, adolescents, and young adults relapsed or refractory to first line.

Cohort 1: Relapsed/Refractory Classic Hodgkin Lymphoma - Low Risk Relapse
Participants started in the induction phase and received nivolumab + brentuximab vedotin (N+Bv) for 2 cycles (6 weeks). Participants with radiographic progression, as assessed by Investigator at Cycle 2 entered follow-up. The rest of the participants continued in the induction phase and received 2 additional cycles of N+Bv study therapy (total 4 cycles = 12 weeks). * Participants who had a complete metabolic response (CMR) by BICR after a total of 4 cycles (12 weeks) of N+Bv received an additional 2 cycles of treatment of N+Bv (for a total of 6 cycles \[18 weeks\]), followed by Radiation Therapy (RT) (consolidation phase). * Participants without a CMR after 4 cycles of N+Bv, by BICR, entered the intensification phase and received 2 cycles of brentuximab + bendamustine (Bv+B); participants who achieved CMR after these 2 cycles proceeded with RT (consolidation phase). * Participants who had radiographic progression after Cycle 4 N+Bv, as assessed by BICR, or those who did not achieve CMR, by BICR, after 2 cycles of Bv+B were taken off study treatment and entered follow-up.

Overall Response Rate (ORR) Following 4 Cycles of Nivolumab + Brentuximab Vedotin Treatment by Blinded Independent Centralized Review (BICR)

Overall response rate (ORR) is defined as the percent of all response-evaluable participants who, assessed by the BICR, achieved a best response of complete metabolic response (CMR) or partial metabolic response (PMR). Complete metabolic response (CMR): * Lymph nodes/extralymphatic sites: Score 1, 2, 3 with/without residual mass on 5-point scale * New lesions: No * Bone marrow: No FDG-avid disease Partial metabolic response (PMR): * Lymph nodes/extralymphatic: Score 4 or 5, reduced uptake from baseline * New lesions: None * Bone marrow: Residual uptake higher than normal, reduced from baseline. Participants who came off early for toxicity without CMR or PMR were evaluable.

Time frame: From first dose to PMR or CMR within 4 cycles of therapy, or the completion of four cycles of therapy (N+Bv x4) (up to approximately 12 weeks).

Population: All treated participants.

Progression Free Survival (PFS) Rate at 3 Years by Blinded Independent Centralized Review (BICR)

Progression Free Survival (PFS) is the time from the date of first treatment to the date of first documented disease progression by BICR or death. Progressive Disease (PD): Lymph Nodes and Lesions: new growth or increase of \>= 50% in size from nadir. New or growing lesions outside the lymph nodes. Spleen: Significant increase in spleen size, either from a previously enlarged state or from normal size. New Lesions: Yes Bone Marrow: New or returning FDG-avid disease. Participants who neither progressed nor died were censored at the last adequate tumor assessment. Participants who started subsequent anticancer therapy (that is not part of high dose chemotherapy followed by autologous stem cell transplant (HDCT/ASCT) Consolidation Therapy for R2 Cohort) without a prior reported progression or death were censored at the last tumor assessment prior to initiation of the subsequent anticancer therapy. Based on Kaplan-Meier Estimates.

Time frame: At 3 years post first dose of study therapy

Population: All treated participants.

The Number of Participants With Adverse Events (AEs)

An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a clinical investigation participant administered study drug and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (such as an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug.

Time frame: From first dose to 30 days post last dose (an average of 4 months up until a maximum of 7 months).

The Number of Participants With Serious Adverse Events (SAEs)

A Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, at any dose: * Results in death * Is life-threatening (defined as an event in which the participant was at risk of death at the time of the event; it does not refer to an event which hypothetically might have caused death if it were more severe) * Requires inpatient hospitalization or causes prolongation of existing hospitalization * Results in persistent or significant disability/incapacity * Is a congenital anomaly/birth defect * Is an important medical event.
