3. Relapsed/Refractory Multiple Myeloma Case 1 76 year-old white female presented in Oct ‘11 w/ Severe mid-back pain Anemia w/ hemoglobin 10.0 Workup: Labs IgG 3760 M-protein 2.62 24-hour urine paraprotein 650 mg B2M 3.7, albumin 3.3 (Stage 2 ISS) Creatinine 1.5 Bone marrow 40% plasma cells Bone survey w/ lytic lesions throughout the axial skeleton and long bones and T10 VCF Patient received initial treatment Kyphoplasty at T10 Zoledronic acid 4 mg monthly Cyclophosphamide, bortezomib and dexamethasone

4. Relapsed/Refractory Multiple Myeloma Case 1 (cont’d) Course Back pain resolved following kyphoplasty After 4 cycles of initial therapy IgG 1170 (from 3760) M-protein 0.59 (from 2.62) 24-hour urine M-protein 45 mg (from 650 mg) Other labs- creatinine 1.0, hemoglobin 11.7 Patient continued treatment for 3 additional cycles w/ myeloma labs increasing IgG 1500 M-protein 0.79 24 hour urine paraprotein 81 mg Other labs- creatinine 1.1, hemoglobin 11.5

5. Relapsed/Refractory Multiple Myeloma: Case 1 At this point, you should Start lenalidomide and oral steroids Stop CYBORD Repeat labs Continue present regimen Start another bortezomib-containing combination

6. Relapsed/Refractory Multiple Myeloma: Case 1 Labs were repeated 1 month later IgG now 1800 M-protein 1.01 24 hour urine M-protein 237 mg Creatinine 1.5; hemoglobin 10.6 What next?

7. Individualize Your Choice for the Myeloma Patient Based on: • How active is the patient? • Mobility? • Is potential neuropathy an issue? (e.g.- surgeon, pianist) • Renal, • Bone, • Marrow, • Subjective, • Rate of ProgressionGenetics? Work/ Lifestyle Disease • Responseand for how long? • Side effects and tolerability • Diabetes mellitus (steroids) • Cardiac (Doxorubicin, PLD) • Neuropathy • (Thalidomide) Prior treatments Co-morbid conditions

8. Principles of Treating Relapsed/Refractory Multiple Myeloma Be sure a patient has really progressed before changing therapy REPEAT MYELOMA LABS! Try to use drugs patient has not seen before HOWEVER, progression on one drug in combination does not mean that drug will not be effective w/ another agent e.g., pts progressing from bortezomib w/ melphalan often respond to bortezomib w/ PLD Even different drugs in the same class may be active so that bortezomib+melphalan failures may respond to other alkylating agents- cyclophosphamide or bendamustine LEN failures may respond to THAL or POM and vice versa bortezomib failures respond to carfilzomib pts progressing from a drug at one dose may respond to the same drug at a higher dose- e.g., LEN the same combination may be effective again if the patient has not seen the combination in a long time

10. Bortezomib + Pegylated Liposomal Doxorubicin (PLD) + Dexamethasone for Patients with Previously Untreated Myeloma:A Phase II Trial PLD: 5 mg/m2 IV infusion Dexamethasone 40 mg IV Bortezomib: 1.0 mg/m2 IV Cycle repeats Days 1 2 3 4 5 6 7 8 9 10 11 29 • MR: 86% • Reduced incidence of PN & PPE Berenson et al.

11. Efficacy and Safety of Bendamustine plus Bortezomib in R/RMM: A Phase 1/2 trial Patients were assigned to one of 3 cohorts receiving doses of intravenous bendamustine at 50 mg/m2 (cohort 1), 70 mg/m2 (cohort 2), or 90 (cohort 3) mg/m2 in combination with a fixed dose of intravenous bortezomib (1.0 mg/m2) according to the schedule in Figure 1. Berenson et al. Brit J Haematol 2012

12. Bendamustine & Bortezomib: Results • No DLT was observed at any dose level • 50 mg/m2 (n = 5) • 70 mg/m2 (n = 4) • 90 mg/m2 (n = 5) • The maximum dose of bendamustine (90 mg/m2) was well tolerated in combination with bortezomib 1.0 mg/m2 and was designated as the MTD • Overall response rate • Overall 48% (1 CR, 2 VGPR, 9 PR, & 7 MR) • At MTD (90 mg/m2) 52% • Bortezomib-exposed (n=31) 42% • Alkylator-exposed (n=28) 46%

13. Lenalidomide + Dexamethasone in R/R MMPhase 3 Trials–Response1,2 • CR rates were significantly higher in the Len + Dex arm of each trial compared with Placebo + Dex (P < .001) • Both OS & TTP superior in Len + Dex arm CR, complete response; nCR, near complete response; Len + Dex,lenalidomide, dexamethasone; PR, partial response; ORR, overall response rate; RRMM, relapsed/refractory multiple myeloma. 1.
