Off-label Discussion Disclosure
This educational activity may contain discussion of published and/or
investigational uses of agents that are not indicated by the Food and Drug
Administration. PCME does not recommend the use of any agent outside of
the labeled indications. Please refer to the official prescribing information
for each product for discussion of approved indications, contraindications

Educational Objectives
At the conclusion of this activity, participants should be able to
demonstrate the ability to:
• Assess the prognosis of patients based on risk stratification and
patient- and disease-related characteristics that influence the
selection of optimal treatment in frontline, maintenance, and
relapsed/ refractory settings
• Review current and emerging maintenance therapy options
considered for MM
• Review treatment options for patients with relapsed/refractory MM
• Identify and manage common treatment-related toxicities in MM
• Evaluate clinical trial opportunities for patients with
relapsed/refractory MM

Multiple Myeloma: Prognosis
• Survival statistics unknown now
– If not high risk, many survive 10 years
– High risk = 3 years
• Some 10%-20% of patients have long-term control with SCT
• Prognosis dictated by host features and genetics
– High risk – 17p13, t(4;14), and t(14;16)
– Gene expression profiling
• Other markers: high LDH, hypodiploidy, IgA, plasmablastic
• International Staging System (ISS) is useful to compare
patients with published data
• ISS has replaced the Durie-Salmon staging system

Who gets a CR?
● Alkylators
and Steroids
● Newer
Agents
– Predominately good risk
– Good and Poor risk
– Low stage
– Addition of new agents
overcomes some poor risk
features
– Hyperdiploid
– Low Proliferation
– CRs occur in the good and
the bad
This change in the spectrum of who
achieves a CR has changed who is ‘at risk’
and adds validity to the newer OS data

• With a median follow-up of 27.3 months median duration of response, PFS,
and OS have not been reached
– 18-month PFS: 75%; 18-month OS: 97%
• Stem cell collection (31 patients)
– Median: 5.6 x 106 CD34+ cells/kg
Richardson PG, et al. Blood. 2010;116(5):679-686.
Frontline Therapy for MM with RVD Regimen
• RVD is highly effective for previously untreated MM
– The first regimen to result in a 100% response rate (≥PR) without ASCT
– Remarkably high rates of CR/nCR and ≥VGPR
• Promising outcomes data; estimated 24-month PFS of 68% and OS of
95% with RVD ± ASCT
• Favorable tolerability over a lengthy treatment period
– Manageable toxicities
– Only 2% G3 sensory PN, 6% DVT; no treatment-related mortality
– All-grade PN 80%, but mainly G1/2 and reversible
– Stem cell mobilization feasible and successful in almost all patients
Richardson et al. 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

lenalidomide/dexamethasone alone?

What would you recommend for Patients #1 & #2 at this

A. Recommend participation in a clinical trial
B. Offer autologous transplantation after successful

C. Allogeneic transplantation after successful induction
D. RVD therapy without collection of stem cells or a

Autologous vs Allogeneic
AUTOLOGOUS
ALLOGENEIC
• High-dose therapy with
reinfusion of own
cryopreserved cells
• Immunosuppressive Rx with
infusion of cells from another
person
• Safer, TRM <5%
• Risk of rejection, GVHD
• Possible contamination with
malignant cells
• Higher risk, TRM 10%-40%
• No graft-vs-malignancy effect
• Lower risk of relapse
• Higher risk of relapse
• Graft-vs-malignancy occurs
• Can perform in diseases in
which blood and BM involved

Role of allogeneic transplant for MM
• Limited utility to most patients due to excessive TRM and
continued risk of relapse
• No evidence that allo grafting improves outcomes for high
risk disease, multiple negative trials
• Is a reasonable option when performed in the context of a
clinical trial testing a new approach, but may limit access
to new agents

Pomalidomide + Low-dose Dex for Relapsed MM
Lacy M et al. J Clin Oncol. 2009;27:5008-5014.
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

Ixazomib (MLN8708) in Relapsed/Refractory
(R/R) MM: Phase I Data
• Phase I data suggest clinical activity in R/R MM patients (median 4
prior lines of therapy)
– ORR (≥PR) of 18%, plus 2% MR, and 30% SD
– Responses seen in patients with prior exposure to proteasome
inhibitors, including patients relapsed after bortezomib.
• Among 50 response-evaluable patients,
– 15 (30%) had M-protein reduction of ≥25%,
– 9 (18%) had best M-protein reductions of ≥50%, including 3 of
≥90% and 1 immunofixation-negative
• A phase III trial in R/R is current recruiting participants
