1 Front Line Therapy for Newly Diagnosed Multiple Myeloma
Vishal Kukreti, M.D., FRCPC Princess Margaret Hospital September 24, 2011

2 Objectives Overview of Myeloma Treatment options First Line Therapy
Transplant Eligible Non-Transplant Eligible

3 Multiple Myeloma Incurable cancer of plasma cells
Medullary and extra-medullary disease

4 Antibodies/Immunoglobulins
Plasma cells make antibodies (immunoglobulins, Igs) which consist of 2 heavy chains and 2 light chains One type of antibody is made to bind with one foreign substance (virus, bacteria, etc.)

5 Patterns of Antibody Production

6 Serum Protein Electropheresis
Normal SPEP Multiple Myeloma

7 Types of Multiple Myeloma

8 Diagnostic Criteria Diagnosis based on finding over 10% plasma cells (antibody forming cells) in bone marrow Symptomatic myeloma characterized by “CRAB” Anemia (<100 or 20g/L below normal) Bone lesions - lytic Kidney damage (Creatinine 176 umol/L) Elevated blood calcium (>2.8mmol/L)

9 Findings at diagnosis - MM
Anemia – 80% Renal dysfunction – 20% Hypercalcemia – 25% Bone destruction – 75% Hyperviscosity - <5% M-protein Identification Serum – 80% Urine – 20% Neither (non-secretory) – 1-2%

10 Age-specific incidence of MM
Transplant candidates Ineligible

11 Staging of Myeloma

12 International Staging System
Risk Category Characteristics 1  2 M  3.5 mg/L + albumin  35 g/L 2  2 M  3.5 mg/L+ albumin  35 g/L or  2 M  3.5 – 5.5 mg/L 3  2 M  5.5 mg/L

13 Survival and ISS score

14 FISH Cytogenetics in Myeloma
p53 deletion=10% (loss of tumor suppressor gene) t(4;14)=15% (dysregulation of FGFR3 and MMSET)

15 Combining Beta 2-Microglobulin and FISH Identifies 3 Prognostic Groups
No t(4;14), no del17p, b2m£4 mg/L, no del13 No t(4;14), no del17p, b2m£4 mg/L, del13 No t(4;14), no del17p, b2m>4 mg/L, no del13 No t(4;14), no del17p, b2m>4 mg/L, del13 t(4;14) or del17p, b2m£4 mg/L t(4;14) or del17p, b2m>4 mg/L 35% 50% FISH - a process which vividly paints chromosomes or portions of chromosomes with fluorescent molecules Identifies chromosomal abnormalities Used to identify the presence and location of a region of DNA or RNA within morphologically preserved chromosome preparations, fixed cells or tissue sections This means you can view a segment or entire chromosome with your own eyes p= 15% Avet-Loiseau H.

19 Novel Agents in Multiple Myeloma
Thalidomide Bortezomib Lenalidomide

20 Agent Class Effects Toxicity Thalidomide (Thalomid®) IMiD Bortezomib
Immunomodulatory effects - inhibits TNFa, inhibits angiogenesis, stimulates T-cells (CD8), alters cytokine production, impedes binding to stromal cells Teratogenicity, PN, sedation, rash, constipation, DVT Bortezomib (VelcadeTM) Proteasome inhibitor Decreased adhesion, cytokine production, angiogenesis, NFkB, DNA repair Fatigue, PN, GI toxicity Decrease in neutrophils, platelets and lymphocytes Lenalidomide (CC-5013; Revlimid®) Stimulate T-cell proliferation, upregulate IL-2 and IFN-g, inhibit TNFa and IL-6Decreased adhesion, alter synthesis of cytokines, induce growth arrest and caspase dependent apoptosis NK cell cytotoxicity Myelosuppression, DVT

21 Strategies to Improve ASCT Results
Improved induction therapy Risk Stratification – t(4;14) Improved dose intensive therapy Tandem ASCT New regimens (“Vel-Mel,” Bu-Mel, busulfex + bortezomib) Post-ASCT therapy Consolidation Maintenance

22 Induction Trials before ASCT
Many phase I-II trials of 3- and 4-drug regimens May allow option to continue regimen without ASCT Phase III trials that include ASCT 3 compare novel regimen with VAD 2 compare novel regimen with thalidomide + dex 1 compares novel regimen with bortezomib + dex

27 Induction Therapy before ASCT - Summary
Advantages of bortezomib-containing induction Rapid induction of remission Effective in renal failure Effective in high-risk cytogenetic subgroups Some evidence that 3- and 4-drug regimens produce higher remissions, and convey better PFS Combinations of bortezomib and IMiDs very costly Weekly bortezomib carries much lower risk of PN PMH approach is to use CYBOR-D x 4 cycles

33 Transplant-Ineligible Patients – Balancing the Toxicities and Efficacy of Novel Agents

34 How do we choose initial therapy in non-transplant patients?
Drug availability Practical considerations Patient-related features Co-morbidities (diabetes, peripheral neuropathy) Marrow reserve Renal function Disease-related features Aggressive biology, such as t(4;14) Light chain nephropathy Treatment related features Rapidity of response Toxicity profile (VTE, peripheral neuropathy)

35 New Treatment Options for Newly Diagnosed Myeloma Patients Non-transplant Candidates
Add novel agent to melphalan + prednisone Continuous suppressive therapy with IMiD + dexamethasone (lenalidomide + weekly dex) Combination therapy with 3-4 drug regimens +/- maintenance CTD • VDC • VMPT6 RVD • VDCR4 CyborD • Thal + dex + PLD5 1Morgan G, et al.

37 IFM 99/06: MPT vs MP vs Mel100 65-75yo
PFS OS MPT MPT MP MP MP (melphalan, 4 mg/m2, days 1-7; and prednisone, 40mg/m2, days 1-7) or MP plus thal (MPT), 100 mg/d for 6 cycles.120 Patients in the MPT arm continued taking maintenance thal after the 6 cycles until relapse. Six months after initiation of therapy, 76% of patients in the MPT arm had a response (CR or PR) compared with 47.6% in the MP arm, which translated to a doubling of EFS at 2 years (54% vs 27%). However, grade 3 and 4 adverse events nearly doubled with the addition of thal (48% for MPT vs 25% for MP), and 11 patients in the MPT group died of toxicityrelated events compared with 6 patients in the MP group. Deep venous thrombosis was the most common grade 3 or 4 adverse event in the MPT group; it developed in 13 of the 9rst 65 patients. After introduction of enoxaparin prophylaxis, thrombosis developed in only 2 of the remaining 64 patients, and that occurred after interruption of enoxaparin. The incidence of early deaths might be reduced in patients younger than 80 years with normal cardiac and pulmonary functions, and with better management of side-effects with antibiotic and anticoagulant prophylaxis.

Also used inadequate VTE prophylaxis for the 1st half of the trial. Enoxaparin 40mg SQ daily prophylaxis added part way thru the study, reducing the VTE rate from 20% to 3% Waage: Certain aspects that may have significance for the differences between the studies are discussed here. There were differences in inclusion criteria between the studies, which was reflected in particular by the fact that 30% of the patients in our study had WHO performance status 3 or 4 compared with 6% to 8% and 6% in the Italian3 and French5,6 studies. The proportion of patients with WHO performance status more than 3 in our study is similar to our earlier population-based, unselected, and nearly complete registra- tion studies.10In addition, the scheduled dose of melphalan and thalidomide varied considerably between the studies. However, none of the studies was designed for evaluating optimal dose of thalidomide, and it is difficult to draw detailed conclusions about dose or duration of treatment and effect across the studies. We notice that beneficial effect has been observed at a dose of 100 mg daily, indicating that a dose in the lower range is sufficientThe median age in all studies was quite similar, ranging from 70 to 74 years in 4 of the studies.3,5,7 Age alone is therefore probably not of major importance. This is further underlined by the French study on patients older than 75 years, which demonstrates a survival benefit of thalidomide.6In conclusion, patient selection and, in particular, differences in proportion of WHO performance status more than 3, differences in dose and schedule of thalidomide and melphalan may have impact on the result. 1Facon T, et al.

49 Conclusions Not all elderly are the same. Not all myeloma is the same
Bortezomib-based induction (e.g. VMP) is reasonably well tolerated and associated with enhanced OS in most patients >65yo and >75yo (and is funded in Ontario) Oral induction regimens (e.g. MPT, MP or len/dex) may be appropriate in some non high-risk patients In patients with renal impairment or t(4;14), -17p a velcade-based induction regimen is preferred (e.g. VMP) Higher intensity regimens less beneficial and may be adverse in frail patients Weekly bortezomib is a new standard of administration Low dose dex is the standard of care in lenalidomide Niesvizky et al.
