Developments in the Treatment of Multiple Myeloma

Kenneth C. Anderson, M.D.

Kraft Family Professor of MedicineHarvard Medical School

Director, Jerome Lipper Multiple Myeloma CenterDana-Farber Cancer Institute

Conflict of Interest: Kenneth C. Anderson, M.D.

Consultancy: Celgene, Onyx, Sanofi Aventis, and Gilead

Scientific Founder: Acetylon, Oncopep

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 MM and now part of induction, consolidation, and maintenance therapy

Nine FDA approvals in the last decade and median survival prolonged from 2-3 yrs to at least 5-7 yrs, with additional prolongation seen from maintenance

New approaches needed to treat and ultimately prevent relapse

Chromosomes and Prognosis in Multiple Myeloma

For conventional low and high dose theapy:

Nonhyperdiploid worse prognosis than hyperdiploid t(11;14), hyperdiplody -standard risk t(4;14), t(14;16),t(14;20), del(17p), del(13q14)-high risk

For novel treatmentsBortezomib, but not lenalidomide, can at least partially overcome t(4;14), del(13q14)-

del(17p) p53 remains high risk

PFS OS

• There was significant prolongation of both PFS (HR 0.49, 95% CI, 0.41–0.58, p<0.001) and OS (HR 0.77, 95% CI, 0.62–0.95, p=0.013) with LM vs. placebo/no maintenance

Results

• Bortezomib-based treatment consistently improves PFS (median 27 m vs 36 m) and OS (median 84 m vs not reached, p=0.05) in patients with newly diagnosed MM who are transplant eligible

• Bortezomib significantly improves the long-term outcome of patients presenting with renal failure (p<0.001)

FIRST Trial: Conclusions

• Continuous Rd significantly extended PFS, with an OS benefit vs. MPT– PFS:

• HR= 0.72 (P= 0.00006)• Consistent benefit across most subgroups• Rd better than Rd18 (HR= 0.70, P= 0.00001)• 3 yr PFS: 42% Rd vs. 23% Rd18 and MPT

– Planned interim OS: HR= 0.78 (P= 0.0168)– Rd was superior to MPT across all other efficacy secondary endpoints

• Safety profile with continuous Rd was manageable – Hematological and non-hematological AEs were as expected for Rd and

MPT– Incidence of hematological SPM was lower with continuous Rd vs. MPT

• In NDMM transplant-ineligible patients, the FIRST Trial establishes continuous Rd as a new standard of care

Conclusions

• The global population is rapidly aging. Aging is associated with an increased incidence of co-morbidity, frailty, and disability.

• PFS and OS appeared similar between the 2- drug and the 3-drug combinations

• Melphalan seemed more toxic than cyclophosphamide

• Fit patients

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

Background: Targeting KSP with ARRY-520 (Filanesib)

• Filanesib is a targeted Kinesin Spindle Protein (KSP) inhibitor

– KSP is a microtubule motor protein critical to the function of proliferating cells

• KSP inhibition induces aberrant mitotic arrest and rapid cell death

– Novel mechanism of action for MM– Preferentially acts on MCL-1

dependent cells including MM– Not expected to be cross-resistant

with other drugs

VANTAGE 088: An International, Multicenter, Randomized, Double-Blind Study of Vorinostat

or Placebo with Bortezomib in Relapsed MM

• The combination of vorinostat + bortezomib is active in patients with relapsed and refractory MM– Significant improvement in response rate– ORR 54% vs 41% (P<0.0001); CBR 71% vs 53% (P<0.0001)

• PFS and TTP were prolonged in the combination arm compared with bortezomib alone

PFS hazard ratio reduction of 23% (P=0.01); 7.63 months (6.9–8.4)versus 6.83 months (5.7–7.7)

• Diarrhea, fatigue, and thrombocytopenia limited tolerability.

• 5 patients withdrew after one cycle and 3 had progressive disease after 2 cycles

• Clinical benefit rate (≥SD): 60%

• 6/10 patients refractory to bortezomib had ≥SD (1 VGPR, 1 MR, 4 SD)

Treatment of Multiple Myeloma: Conclusions

• In newly diagnosed transplant candidates, three drug regimens incorporating immunomodulatory drugs and proteasome inhibitors before and after transplant can prolong PFS and OS.

• Lenalidomide dex until progression is standard of care for non transplant patients with newly diagnosed myeloma.

• Lenalidomide maintenance until progression prolongs PFS and OS, with an increased risk of secondary cancers in patients who have received MP or high dose therapy and ASCT.

Treatment of Multiple Myeloma: Conclusions

• Pomalidomide low dose dex is active in relapsed refractory MM, (including 17p deletion)

• Bortezomib or Carfilzomib and pomalidomide low dose dex increases response and is tolerated in relapsed refractory MM

• Novel agents including oral proteasome inhibitor ixazomib, monoclonal antibodies SAR650984 and daratumumab, immunotoxin indatuximab, KSP inhibitor filanesib, Akt inhibitor afuresertib, and HDAC6 inhibitor ricolinostat demonstrate promising activity in relapsed refractory MM

• Incorporation of novel therapies at all stages of disease is further improving patient outcome in MM
