Emerging therapeutic options for relapsed/refractory multiple myeloma Meletios A. Dimopoulos, MD Department of Clinical Therapeutics, National and Kapodistrian University of Athens, School of Medicine, Athens, Greece

2 Prompt treatment initiation needed
Relapse situations Two clear scenarios Slow, asymptomatic relapse No symptoms Slowly progressing disease Low tumor burden Cytogenetic low risk Good performance status Fast, symptomatic relapse Symptoms Radiply progressing disease High tumor burden Organ involvement Cytogenetic high risk Poor performance status Observation Prompt treatment initiation needed The challenge: Identify appropriate time to initiate treatment for situations ‘in between‘

3 Multiple factors drive treatment choice in relapsed/refractory MM
Prior therapies received† Tolerance to prior therapies Time interval since last therapy Influential factors Side effects Subtype e.g. t(4;14) Comorbidity e.g. renal impairment* Age Previous SCT Treatment availability Pre-existing toxicities e.g. PN Performance status *Occurs in up to 50% MM patients; †Can repeat induction therapy where relapse occurs >6 mo. after treatment PN, peripheral neuropathy; SCT, stem cell transplant Moreau P, et al.

6 ...But IMiDs (thalidomide mainly) and bortezomib are used in first line therapy
What are the implications for treatment at relapse? How can relapse under treatment, e.g. maintenance treatment, be managed? Is retreatment feasible?

7 Is retreatment with novel agents feasible?

47 Filanesib (ARRY-520): Mechanism of action
Cancer cell Normal spindle: proliferation Monopolar spindle: arrest & apoptosis KSP ARRY-520 ARRY-520 is a kinesin spindle protein (KSP) inhibitor KSP inhibition prevents formation of bipolar spindle Inducing rapid apoptosis leading to cell death Shah JJ, et al. Blood. 2012;120:[Abstract 449].

49 Summary/Conclusions Treatment at relapse influenced by patient, disease and treatment factors; distinction between biochemical and clinical relapse necessary Bor, Thal and Len have improved outlook for patients with RR MM Range of effective combinations available: KRD another “standard of care” in this setting Retreatment with novel agents feasible Pomalidomide and carfilzomib produces high response rates and increases survival in patients who are refractory to both len and bor. Their combination is more effective but also more expensive! New classes of agents are of considerable interest and have antimyeloma activity (more promising: mAbs, panobinostat, ricolinostat, filanesib), mainly in combination with known anti-myeloma agents.
