• Patients: Favorable in 68%, unfavorable in 32%.• CR rates: After BV, 18 pt (53%). After 2 A-AVD, 33 pt (97%).
At end of therapy, CR=88%, and 6/8 Pos PETs were false positive (? due to BV).
• Gr 3-4 AEs: FN in 29%, PN in 24%• At med f/u of 14 mo, PFS=90% and OS= 97%.• Randomized study needed to prove benefit of BV
Phase I/II Brentuximab Plus Bendamustine for Relapsed/Refractory HL
• CR rates for Rel/Ref HL with standard agents range 19-60%– Brentuximab vedotin alone: CR 34%– Bendamustine alone: CR 33%
• Treatment Plan: 1.8 mg/m2 BV day 1, Benda 90 mg/m2 days 1,2.– Cycles repeated q 3 wks– Benda de-escalated if DLT (delay of > 2 wk) in > 3/10 pts.
• Tolerability: No DLT reached• Infusion Reactions before adding Steroids and Antihistamines

PET vs CT for Stage I-IV HL: PFS by Radiographs after 2 CT Cycles

Reasons for the “False Positive” PETIntrinsic – hardware
– Improved detectionCriteria for positive
– Visual or SUV– Reader variation
Benign variants– Sarcoidosis– Thyroiditis
Inflammation– Infection– Trauma
Iatrogenic causes– Injections– Post RT– Post Surgery
Type/Location of lymphoma– Marginal Zone/SLL/T-Cell– Bowel, Marrow Disease– Hyperplasia?
Other tumors– Benign
• Warthin’s• Thyroid adenomas• Bowel adenomas
– Malignant (Any)Therapy
– Use of Rituximab– G-CSF
Timing of scan– How many days after last
chemotherapy
Routine Imaging Strategies (RIS) for Classical HL in First Remission
• Three centers: Retrospective comparison of Clinical (CS) and RIS• RIS by NCCN: Imaging Q 6 mo for 2-3 yearsChemotherapy: ABVD - 79%, Stanford V - 15%
Pingali et al, ASCO 2013 # 8505.
Group Mean # scans
% Deaths
% Relapses
Scans per Relapse
CS, n=77 1.14 4.6 6.6 17.6RIS, n=164 4.25 5.3 4.6 122.3
• RIS conferred no OS advantage (p=0.47)• CR rates with relapse therapies were also similar for CS and RIS Suggests that routine imaging after
therapy is completely unnecessary.

PET Scan Results From the RAPID Trial: Prognostic Value of the Positive PET
Radford et al. ICML-13, 2015, #82
• Positive PET after 3 ABVD defined as Deauville score of 3-5
• 145 received a 4th ABVD and IFRT• 88% and 85% had risk criteria to define EORTC
and GHSG favorable HL (66% and 68%, respectively).
• P values by MVA: PET 3-5: 0.001, EORTC: 0.48, GHSG: 0.62
• By Hazard Ratios: PET 5 vs 4- 6.7, vs 3- 9.3, vs 2- 3.2, vs 1- 5.1.

were closed to patient entry.

Update on Therapy for Hodgkin Lymphoma: ASCO/ICML
1. Brentuximab Trials• Single Agent Therapy• Combination Programs
2. PET-Driven Therapy• Stage I-II Disease• Stage III-IV Disease
3. Novel Agents• Anti-PD-1 for Relapse • Gem/Bu/Mel for SCT
PD-1 is Inactivated by PD-L1 and PD-L2 on Tumor Cells
• PD-1 is a protein on T-Cells that dampens the normal immune response•Tumor cells can evade normal T-cell attack• Inactivate T-cell function by activation of PD-1 via PD-L1 and PD-L2
• T-Cells are “exhausted”• Cannot attack tumor cells• Inactivation is reversible
PD-L1 is Upregulated in Tumor cells• Chromosome 9p24.1 amplification upregulates
PD-L1, as can EBV infection• Multiple tumor types utilize the PD-L1 and PD-L2
interaction with PD-1 to escape immune surveillance– Breast, NSCLC, Kidney, Colon, Melanoma,
Hematologic Malignancies overexpress PD Ligands– Pembrolizumab FDA-approved for Metastatic
Melanoma– Nivolumab recently approved for Metastatic
Melanoma– Ongoing studies in many other tumors
Phase I Nivolumab in Rel/Ref HL: Preliminary Safety, Efficacy and Biomarker Results
• 23 Hodgkin lymphoma patients from larger study in hematologic malignancies– Dosing: 1-3 mg/kg with no MTD reached in Phase I– Expansion cohort 3 mg/kg chosen, week 1, 4 and q 2
wk for maximum 2 years• Drug-related adverse events (> 10%, all reversible)
