Integration of Novel Therapy Into Myeloma Management Bortezomib, Lenalidomide, Thalidomide, Doxil, Carfilzomib, Pomalidamide Target MM in the BM microenvironment to overcome conventional drug resistance in vitro and in vivo Effective in relapsed/refractory, relapsed, induction, consolidation, and maintenance therapy Eight FDA approvals and median survival prolonged from 3-4 to 6-7 years, with additional prolongation from maintenance New approaches needed to treat and ultimately prevent relapse
Relapsed or Intolerant There is a well defined and recognized unmet need in multiple myeloma treatment Adapted from: Durie BGM. Multiple Myeloma. International Myeloma Foundation. 2011/2012 edition. Jagannath S. Clin Lymphoma Myeloma. 2008;8 Suppl 4:S149-S156. Unmet Need Relapsed Frontline Treatment Frontline Treatment Expected survival (m) 20-50 Sensitivity to therapy Sensitive Treatment limitations/ comorbidities Peripheral neuropathy (~15% at diagnosis) 14-16 Less Sensitive/Resistant >80% incidence of peripheral neuropathy Compromised marrow reserve Cytopenia 6-10 Resistant Intolerant to or ineligible for available therapy Elderly population ( risk for heart, lung, renal, liver dysfunction, diabetes)

Lenalidomide induces caspase 8 mediated apoptosis of MM cells in BM in vitro and in vivo; Dex (caspase 9) enhances response Synergistic MM cell toxicity of lenalidomide (caspase 8) with Bortezomib (caspase 9>8) in vitro and in vivo (dual apoptotic signaling) Phase I-II trials show that majority (58%) of patients refractory to either agent alone respond to the combination Phase I-II trials show 100% response with 74% CR/VGPR and 52% CR/nCR when used as initial therapy, including molecular responses.

CRd in Relapsed and Upfront MM Wang et al ASCO 2011; Jakubowiak et al ASH 2011 Response to CRd therapy was high, with an ORR of 78% –41% VGPR or better CRd well-tolerated with durable responses ASPIRE phase 3 open-label, international, multicenter trial comparing CRd to Rd in R/R MM fully enrolled.

Phase II Study of Infusional Carfilzomib in Patients with Relapsed or Refractory MM CFZ dose of 20/56 mg/m 2 administered as a 30-minute IV infusion resulted in high response rates in our BTZ treated/refractory population. Response rates were comparable to those seen in PX- 171-007 1 CFZ dose of 20/56 mg/m 2 was associated with more frequent cardiac and pulmonary toxicities, particularly HTN and pulmonary edema/CHF. –Possible contribution from “supportive” measures? CFZ dose of 20/56 mg/m 2 continues to be explored in ongoing Phase II/III studies. Lendvai et al, ASH 2012 Abstr 947

Pomalidomide With Low-Dose Dexamethasone Relapsed and Refractory Multiple Myeloma POM was effective in heavily pretreated patients who had already received LEN and bortezomib and who progressed on their last line of therapy The combination of POM with LoDEX improves the ORR due to synergy between immunomodulatory agents and glucocorticoids –POM + LoDEX, 34%; POM alone, 15% Response was durable with POM regardless of the addition of LoDEX –POM + LoDEX, 8.3 months ; POM alone, 8.8 months POM is generally well tolerated, with low rates of discontinuations due to AEs Age had no impact on ORR, DoR, or safety Jagannath S, et al. ASH 2012 abstract 450.
Pomalidomide Plus Low-Dose Dexamethasone (Pom/Dex) in Relapsed Myeloma (345 patients) Pom/Dex has high response rates even in heavily pretreated relapsed myeloma Pom/Dex is well tolerated Toxicity and efficacy are similar between the 2mg and 4mg dose levels The strongest predictors of response include the number and type of prior regimens. The strongest predictors of TTP and survival include the number and type of prior regimens, LDH, and B2M. Lacy et al. ASH 2013 Abstr 201.
A Phase III Clinical Trial of Pomalidomide with Low-dose Dex vs. High-dose Dex in Relapsed/Refractory MM POM + LoDEX significantly improved PFS and OS –Median PFS: 3.6 vs 1.8 months HR = 0.45; P <.001 –Median OS: not reached vs 7.8 months HR = 0.53; P <.001 Equal benefit in pts refractory to both LEN and BORT POM + LoDEX was generally well tolerated POM + LoDEX should be considered as a new treatment option for these pts Dimopoulos et al.

Carfilzomib Pomalidomide Dexamethasone (Car-Pom-d) in Relapsed/Refractory MM MTD was Carfilzomib 20/27 mg/m 2, Pomalidomide 4 mg, and dexamethasone 40 mg There are limited G 3 and 4 non hematologic toxicities; the regimen was tolerated well with no unexpected toxicity The combination of Car-Pom–d is highly active in this heavily pretreated, refractory patient population The combination has encouraging preserved response rate and survival independent of FISH/cytogenetic risk status ≥ VGPR13% ≥ ORR50% ≥ CBR67% PFS (median)7.4 months OS90% @ 1 year Shah et al.

PD-L1 Plays an Important Role in Dampening the Anti-tumor Immune Response Stromal PD-L1 modulation of T cells Immune cell modulation of T cells PD-L1/PD-1-mediated Inhibition of tumor cell killing IFN - mediated up-regulation of tumor PD- L1 Priming and Activation of T cells PD-L2 mediated inhibition of TH-2 T cells receptor Chen DS, Irving BA, Hodi FS. Clin Cancer Res. 2012;18:6580. PD-L1 expression in the tumor microenvironment can inhibit anti-tumor T cell activity: 1.PD-L1 expression by tumor infiltrating immune cells 2.PD-L1 expression by cancer cells cancer cell PD-L1 lymphocyte Presence of intratumoral T-cells may lead to adaptive immune resistance
Combination Immunotherapy Posttransplant Anti PD-1 Ab administration in the early post-autologous transplant period is well tolerated Anti-PD1 results in the expansion of tumor reactive lymphocytes in the post-transplant period that persist at 6 months This provides a promising platform for combination with a tumor vaccine We have inititated enrollment into cohort 2, in which patients receive an autologous DC/myeloma fusion vaccine 1 week prior to each dose of Anti-PD-1Ab Avigan et al.

1.Lenalidomide dexamethasone, bortezomib, and pegylated doxorubicin are approved regimens for relapsed MM. 1.Pomalidomide/dex and carfilzomib are newly FDA approved options. 3.There are many promising protocols of novel immune and targeted agents which show promise, alone and in combination. 4. Genomic analyses are both defining the basis for evolution underlying relapse and identifying new targets. Relapsed Refractory Myeloma
