Brief Summary:

This is a multi-center, open-label phase II study to assess the efficacy of a novel fitness-adapted regimen in previously untreated older patients with classical Hodgkin lymphoma. All participants will receive up to a total of 8 cycles of pembrolizumab (Q6 week dosing). The first cycle of pembrolizumab will be administered in combination with brentuximab vedotin (BV) ("lead-in treatment").

Following lead-in treatment, all participants will undergo interim PET/CT (iPET) as well as fitness testing to help inform participant level of fitness for subsequent lymphoma-directed therapies.

Participants deemed "non-fit" by this assessment will continue 3 additional 6 week cycles of concurrent pembrolizumab and BV ("induction therapy", each cycle is 42 days), then continue single-agent pembrolizumab to complete up to 4 additional cycles (i.e., 8 total) of therapy ("consolidation and maintenance therapy", Non-Fit cohort). Two additional BV doses will be given as consolidation, at days 1 and 22 of pembrolizumab cycle 5.

Those deemed "fit" after lead-in therapy (Fit cohort) will continue pembrolizumab and switch from BV to concurrently-administered combination chemotherapy using doxorubicin (A), vinblastine (V), and dacarbazine (D) for a total of 4 planned AVD cycles (3, 6-week pembrolizumab cycles, "induction therapy"). Chemotherapy drugs will be given at standard doses as in ABVD (no bleomycin will be given in this study) on days 1 and 15 of each 28-day cycle (C1AVD), and pembrolizumab dosing will remain every 42 days. Following end-induction PET/CT, pembrolizumab will continue every 42 days for up to 4 cycles in the consolidation/maintenance phase. Two additional BV doses will be given as consolidation, at days 1 and 22 of pembrolizumab cycle 5.

Primary Outcome Measures :
  1. Complete Remission Rate [ Time Frame: 2 years ]
    Evaluate complete remission rate as defined by LYRIC criteria at end of induction in fit older participants with cHL following anthracycline-based chemotherapy.

  2. Incidence of grade 3-5 treatment-related AEs [ Time Frame: 2 years ]
    Assess tolerance and safety of a fitness-adapted pembrolizumab-based regimen in fit older participants with cHL based on incidence of grade 3-5 treatment-related AEs (CTCAE v5.0)

Secondary Outcome Measures :
  1. 2-year PFS, 2-year OS, 2-year Lymphoma Specific Survival in the fit older population following pembrolizumab-based adaptive therapy [ Time Frame: 2 years ]
    Evaluate the efficacy, as determined by the 2-year progression free survival (PFS), overall survival (OS), and 2-year lymphoma specific survival in the fit older population.

  2. Complete remission rate (by LYRIC criteria), 2-year PFS, 2-year OS, 2-year Lymphoma Specific Survival in the non-fit older population [ Time Frame: 2 years ]
    Evaluate the efficacy of a chemotherapy-free approach (pembrolizumab plus BV), as determined by the complete remission rate (LYRIC criteria), 2-year progression free survival (PFS), overall survival (OS), and 2-year lymphoma specific survival in participants who are not fit for anthracycline-based therapy.

  3. Complete remission rate (LYRIC criteria) after lead-in BV/pembrolizumab [ Time Frame: 2 years ]
    Assess the efficacy of short course lead-in therapy and correlation with end-induction treatment efficacy for all participants.

  4. Incidence of grade 2-5 immune-related toxicities (CTCAE v5.0) [ Time Frame: 2 years ]
    Assess safety, as determined by the frequency of higher-grade immune-related adverse events for all participants.

Other Outcome Measures:
  1. Rate of Indeterminate Response (LYRIC criteria) [ Time Frame: 2 years ]
    Assess the rate of "indeterminate response" by LYRIC criteria at interim and end-induction PET/CT and correlate with the presence of active Hodgkin lymphoma on biopsy (when available) and clinical outcome for all participants.

  2. Incidence of change in fitness assignment from baseline assessment. [ Time Frame: 2 years ]
    Evaluate and summarize incidence of changes in fitness assignments throughout therapy.

  3. Incidence and Severity of treatment-related toxicities [ Time Frame: 2 years ]
    Summarize participant fitness throughout therapy by incidence and severity of treatment-related toxicities.
