2 Hodgkin Lymphoma Successes and Challenges The success 80 % of patients achieve a complete response The ongoing challenges ~ 30% of patients relapse Optimal chemotherapy regimen ABVD vs.. Treatment of older patients Reduce toxicity of standard therapy More effective therapy for advanced stage and primary refractory and relapsed disease

3 CD30 Targeted Therapy Pivotal study in 102 patients with relapsed/refractory HL after ASCT -75% objective response rate with brentuximab vedotin -34% complete response rate Younes A, et al. J Clin Oncol. 2012;30(18):

4 PD-1 Immune Checkpoint Pathway Classical Hodgkin lymphoma (chl) is characterized by expression of PD-L1 and PD-L2 on malignant Reed Sternberg cells and on inflammatory cells in the tumor microenvironment PD-L1 expression in chl frequently occurs in the setting of genetic amplification of the 9p24.1 locus PD-L1 expression in chl Copy Gain Amplification PD-L1/L2 copy gains and amplification visible by FISH Chen BJ, et al. Clin Cancer Res. 2013;19(13): Ansell SM, et al. N Engl J Med. 2015;372(4): Ansell SM, et al. Blood. 2015;126: Abstract 583.

30 Results From a Phase 1/2 Study of Brentuximab Vedotin in Combination With Nivolumab in Patients With Relapsed or Refractory Hodgkin Lymphoma Abstract 649 Herrera AF, Moskowitz AJ, Bartlett NL, Vose JM, Ramchandren R, Feldman TA, LaCasce AS, Ansell SM, Moskowitz CH, Fenton K, Ogden CA, Taft D, Zhang Q, Kato K, Campbell M, Advani RH

31 Study Rationale BV activates the immune system and initiates an antitumor response through the induction of immunogenic cell death Nivolumab targets PD-1 and restores an effective antitumor response Herrera AF, et al. Blood. 2017;130: Abstract 649.

32 Methods Target enrollment: ~55 patients Patients were treated in 21-day cycles for up to 4 cycles (12 weeks) During Cycle 1, BV was administered on Day 1 and Nivo on Day 8 During Cycles 2-4, dosing of both drugs occurred on Day 1 of each cycle After completion of the Cycle 4 response assessment, patients were eligible to undergo ASCT Investigator assessment of lymphoma response and progression was per the Lugano Classification Revised Staging System for malignant lymphoma (Cheson et al, 2014) Herrera AF, et al. Blood. 2017;130: Abstract 649.

33 Patient Characteristics and Disposition Herrera AF, et al. Blood. 2017;130: Abstract 649.

34 Herrera AF, et al. Blood. 2017;130: Abstract 649. Response

35 Brentuximab Vedotin + Nivolumab BV + Nivo was well tolerated 44% of patients experienced IRRs, 41% Gr 1-2, 3% Gr 3 <10% had potential iraes requiring steroids Treatment did not impact stem cell mobilization and stem cell collection: patients were able to proceed to ASCT uneventfully BV + Nivo treatment resulted in Increasing circulating T-cell numbers, and increase in adaptive immuneactivating cytokines and chemokines Increased ability of memory T-cells to mount an immune response Herrera AF, et al. Blood. 2017;130: Abstract 649.
