22  BTK inhibitor, an oral agent, showed promising activity as a single agent in untreated elderly pts (>65 yo) with CLL/SLL (John Byrd 2012 ASCO) - N = 26 - ORR 81%, CR 12% with medium f/u 14 mos  Ofatumumab is active in fludarabine- or alemtumumab-refractory CLL/SLL pts: ORR approximately 50% Wierda, et al., JCO 2010

23  Ibrutinib 420 mg po qd  Oftumumab - 300 mg C2, day1 - 2000 mg C2,days 8, 15, 22 - 2000 mg C3, days 1, 8, 15, 22 - 2000 mg C4-8, day 1 only

24  To determine the toxicity of the combination regimen - Tolerability is defined as no more than 1 DLT in the first 6 pts treated for 2 cycles  To evaluate ORR at one year: N = 27, including the initial 6

25  CLL/SLL or Richter’s transformation  Two or more prior therapy, including a purine analog- containing regimen  More than 10% CD20 expression on CLL cells by flow cytometry  Adequate organ functions

37 Topp, et al., JCO 2011 80% 15 ug/m 2 /24 hrs CIV x 4 weeks, 2 weeks off, q 6wk-cycle

38  Dose-finding Phase: - Cohorts: 1, 2a, 2b  Expansion Phase:  Dosing: CIV 4 wks on, 2 wks off, for up to 5 cycles - CR/CRh within the first 2 cycles -> allo  Primary Endpoint: CR/CRh within 2 cycles

39  R/R ALL, > 5% blasts in BM  Ph+ and relapsed after allo were permitted

40  Selected dose for expansion cohort based on lowest treatment-related AEs (3/5 pts): 5ug/m2/d CIV week 1, then 15ug/m2/d CIV thereafter

41 N = 23 Median Age 31 (21 – 66) Refractory1 (4%) Relapsed21 (91%) 1 st relapse <= 18 mos 9 (43%) 1 st relapse > 18 mos4 (19%) >= 2 nd relapse8 (38%) Prior SCT10 (43%) Ph +2 (9%) T (4,11)1 (4%) Blasts in BM >60%12 (52%) 10% - 60%6 (24%) < 10%4 (17%)

42  Cytokine release syndrome - Risks: high tumor burden ans without cytoreductive phase - Prevention: cytoreduction 5ug/m2 wk 1 and give Dex for BM>50%  CNS Adverse Events: - 3 seizures and 3 encephalopathy: fully reversible - all 6 pts continued at 5 ug/m2  One pt died of fungal infection

43  CR/CRh: 17/23 pts (74%)  All but 2 responders achieved molecular remission  High remission rate in all pt groups, including Ph+  13 pts received an allogeneic SCT  With a median follow-up of 4.5 months, median duration of response was 8.9 for all cohorts, not yet reached for the expansion cohort

44  Well-tolerated at 5 ug/m2/d followed by 15 ug/m2/d CIV, 4 weeks on, 2 weeks off  High hematologic and molecular response rate  Median duration of complete hematologic response was 8.9 months  Median survival was 9 months

45 Carfilzomib Coming to the Front-line

46  Disease status - High risk, intermediate risk vs low risk - special clinical scenarios: plasma leukemia, renal failure  Patient factors - Transplant eligibility - PS and comorbidity  Clinical benefit - response and OS - QOL  Toxicity and convenience  Cost

82  Highly active as a first-line treatment for MM  The quality of response seems improved in some studies  Tolerability seems improved with minimum peripheral neuropathy, although comparison with SQ bortezomib remain to be investigated

83  Lymphoma and CLL/SLL The Stil trial established R-Benda as the preferred first-line treatment for FL and MCL Ofatumumab + ibrutinib (Btk inhibitor) is highly active in relapsed/refractory CLL/SLL  Acute Leukemia Blinatumumab (Bite biphasic antibody) is highly active in relapsed/refractory ALL  Multiple Myeloma Carfilzomib is moving to the front line
