Blood 116: 2010 (679-686); Anderson, et al. J Clin Oncol 28:15s, 2010 (suppl; abstr 8016) What Toxicities Should You Monitor in These Patients? IMID-associated Deep Venous Thrombosis • Pathophysiology unclear – MM, unlike solid tumor does not express tissue factor – Platelet activation via cathepsin G • Prevention is key – Low risk aspirin – High risk anticoagulation • High dose dex, immobility, prior DVT, comorbidity • Pearls – Continue until at least 1-2 months post completion – Do not forget to bridge for surgical procedures – Not a reason to abandon treatment Palumbo A et al. Blood Rev. 2011;25:181-191. Richardon PG et al. Leukemia. 2012;26:595-608. Other Toxicities: Peripheral Neuropathy • Peripheral neuropathy (PN) – one of the most important complications of MM treatment • PN can be caused by MM itself, and particularly by certain therapies, including bortezomib, thalidomide, vinca alkaloids, and cisplatin • Up to 20% of MM patients have PN at diagnosis, and as many as 75% may experience treatment-emergent PN during therapy • Bortezomib causes any grade PN in 31% to 47% patients • Lower-than-expected rates of severe PN with bortezomib plus lenalidomide combinations, with grade 3 PN rates of 3% and 2% with bortezomib, lenalidomide, and dexamethasone (RVD) in frontline and relapsed/refractory patients, respectively Palumbo A et al.

Pomalidomide + Dex in Relapsed MM • Pom + LoDex vs HiDex significantly extended PFS and OS in pts who failed LEN and BORT. • Toxicity is manageable and consists primarily of hematological toxicity • Effective in high-risk patients • Pomalidomide combinations should be explored (e.g, Pom/Bor/Dex, second generation PIs, alkylating agents) San Miguel et al, 2013, ASCO, abstr 8510; Lacy et al, 2009, JCO, 27(30): 5008-5014; Lacy MQ, et al. Haematologica. 2011;96(1):s21 Elotuzumab + Len/Dex Study • Elotuzumab is a humanized IgG1 mAb targeting human CS1, a cell surface glycoprotein • CS1 is highly expressed on >95% of MM cells – Lower expression on NK cells – Little to no expression on normal tissues • Results look very good for this patient population and justify phase III studies – ORR 84% (92% in elotuzumab 10 mg/kg group) – ORR 91% if 1 line of therapy – PFS NR for 10 mg/kg and 18.6 months for 20 mg/kg Lonial et al., ASCO 2012, Abstract 8020; Richardson et al., ASH 2012, Abstract 202. Next Steps for Elotuzumab + Len/Dex • Two ongoing Len/Dex +/- Elotuzumab studies • Bor/Dex +/- Elotuzumab phase II study initiated (abstract #92855) • Can we do even better by combining elotuzumab with 3-drug regimens or other agents? – Is cost going to be a concern? • How to use elotuzumab in LEN-refractory patients may need to be addressed • Lower PFS in high-risk patients is disappointing – There is a potential for relative benefit Lonial et al., ASCO 2012, Abstract 8020; Richardson et al., ASH 2012, Abstract 202.

ARS Question 11 A 55-year-old female patient presents with asymptomatic anemia of 10g/dL and total serum protein 10 g/L. The workup reveals multiple lytic lesions, an IgA kappa peak of 3.2, cytogenetic t4:14, 30% plasma cells, and Beta 2 microglobulin of 5.0. Which of the following treatment options is not a suitable choice for this patient? A. Thalidomide + dexamethasone (TD) B. Lenalidomide + dexamethasone (RD) C. Bortezomib + dexamethasone (VD) D. Lenalidomide + bortezomib + dexamethasone (RVD) E. Thalidomide + melphalan + prednisone (TMP) ARS Question 12 Which of the following is not a supportive care consideration that you would discuss with your patient being treated with a lenalidomide + dexamethasone regimen? A. There is a very high risk of peripheral neuropathy with this regimen B. Prophylactic treatment for deep vein thrombosis should be initiated C. Anticipate the possibility of infection D. Long-term complications might include diarrhea and fatigue ARS Question 13 A 72-year-old male is diagnosed with MM. The work up revealed 3 compression fractures; anemia; 60% kappa plasma cells; IgG 4200 mg/dL; kappa FLC 79 mg/dL; beta 2 microglobulin 8; creatinine 1.0, normal calcium; FISH shows hyperdiploidy; and comorbidities include diabetes, hypertension, obesity, and atrial fibrillation. He is treated with frontline lenalidomide + dexamethasone. However in a month his creatinine worsened to 1.7 mg/dL and the regimen is poorly tolerated.
