Considerations for Optimizing Transplant in Multiple Myeloma Patient Management The first 68 slides of this library should be considered a sample presentation only. You should customize your presentation using the slides in the library, keeping in mind that the learning objectives must be met. Considerations for Optimizing Transplant in Multiple Myeloma Patient Management Learning Objectives After completing this program, participants should be able to: 1. Identify factors that might determine eligibility for and timing of high-dose chemotherapy (HDT) followed by autologous stem cell transplant (ASCT) in patients with multiple myeloma (MM) 2. Differentiate treatment strategies for patients with newly diagnosed multiple myeloma who are eligible for HDT/ASCT 3. Identify barriers in access to HDT/ASCT for MM 4. Review the rationale for conditioning regimens in patients with multiple myeloma who are eligible for HDT/ASCT 5.

MELPHALAN CHALLENGES PK Variability Propylene Glycol Special Issues MEL Pharmacokinetics • Inter-individual variability – Creatinine Clearance – Fat free mass – Hematocrit • Higher MEL exposure—increased toxicity and efficacy • Unbound MEL—sensitive predictor of toxicity and efficacy Nath, et al. Br J Clin Pharmacol. 2010;69:484-497. Special Issues with Melphalan: Renal Impairment • Up to 50% of newly diagnosed patients have a decrease in creatine clearance and ∼9% require dialysis because of severe renal impairment [1] • No change in the pharmacokinetics of high-dose melphalan in patients with renal failure[2,3] – Outcome similar to patients with preserved renal function • Similar results observed in a series of 81 MM patients with renal failure (38 patients on dialysis)[4] – Renal failure did not affect the quality of stem cell collections or engraftment – Median OS >52 months (similar to patients with normal renal function) – CR rate was not significantly affected by dialysis dependence (37% in dialysis patients vs 33% in the non-dialysis group; P=.07) [1] Knudsen L, et al. Eur J Haematol.1994; 53: 207–212. [2] Tricot, et al. Clin Cancer Res. 1996;2:947-952. [3] Jagannath, et al. Blood. Special Issues with Melphalan: Renal Impairment • Melphalan 140 mg/m2 as effective as melphalan 200 mg/m2 with less toxicity in patients with renal impairment[1] – Mucositis: 93% (MEL-200) vs 67% (MEL-140); P= .04 – Pulmonary complications • 57% (MEL-200) vs 17% (MEL-140); P=.007 • 53% (dialysis-dependent) vs 19%; P= .02 – Cardiac complications • Atrial dysrhythmias significantly more common in MEL-200 group • 21% (MEL-200) vs 0 (MEL-140); P = .07 – Neurological complications • More common in MEL -200 group (36% vs 27%, P = .6) • Significantly more common in dialysis group (47% vs 6%; P = .005) 1. Badros A, et al. Br J Haematol. 2001; 114:822–829. Special Issues with Melphalan: Renal Impairment • Pharmacokinetics of MEL are no different in renal-impaired patients BUT – More leukopenia noted in patients with renal impairment in early studies – MEL-200 poorly tolerated by patients with renal dysfunction – 60% MEL can be recovered from urine • Auto-SCT should be performed early in the disease course before renal failure becomes irreversible1 – MEL-140 is associated with less toxicity and equal efficacy to MEL200 in patients with renal failure – Renal failure patients with low albumin had a higher treatment-related mortality and may do better with even lower doses of MEL (70 ± 100 mg/m2) 1. Badros A, et al. Br J Haematol. 2001; 114:822–829. Special Issues with Melphalan: Mucositis • MEL-ASCT is associated with severe oral mucositis (OM) – OM develops in 45%-75% of patients[1,2] – Predictors of severe OM[1] • High serum creatinine • High mg/kg melphalan – Severe OM risk and/or duration was significantly associated with:[2] • Higher chemotherapy dose/kg of body weight • Poor performance status • NOT related to age [1] Grazziutti ML,et al. Bone Marrow Transplant. 2006;38(7):501-506. [2] Blijlevens N, et al. J Clin Oncol. 2008;26(9):1519-1525. Cryotherapy Prevents OM in MM Patients Receiving High-dose Melphalan • 117 MM patients randomized to receive cryotherapy (CT) + saline solution (SS) mouth rinse, SS alone, or supersaturated calcium phosphate rinses[1] – No OM: 90% of patients in the CT group vs 36% (supersaturated calcium phosphate rinse) and 34% (SS) (P < .0001) – No grade 3-4 OM in the CT group • Meta analysis of 7 RCTs including 458 patients with hematological malignancies undergoing HSCT[2] – Oral cryotherapy significantly reduced • The incidence of severe OM • OM severity • The duration of total parenteral nutrition use • The length of hospitalization [1] Toro, et al. BBMT . 2014;20 :S204 - S205. [2] Wang, et al. PLoS One. 2015; 10(5): e0128763. Special Issues with Melphalan: Administration • When reconstituted, Melphalan rapidly hydrolyzes ~1% every 10 minutes • Manufacturer recommendations: – Dilute dose in NS to </= 0.45 mg/mL and infuse over at least 15 minutes – Complete the infusion within 60 minutes of reconstitution of the vial • BMT programs should verify that infusions have ended before the Melphalan expiration time/date Special Issues with Melphalan: Administration • Example: Patient 2.1 m2 ordered 200 mg/m2 • A dose of 420 mg diluted in 933 mL NS (0.45 mg/mL) must infuse @ 1867 mL/h administer the dose over 30 minutes • The dose is prepared as 2 bags (466.5 mL each) to infuse simultaneously with each pump @ 933 mL/h – A typical infusion pump has a maximum infusion rate of 999 mL/h Special Issues with Melphalan: Stability • Highly unstable in solution • 10% per loss of activity/ hr • Propylene Glycol (PG) – Additive to MEL – Toxic in the ICU setting when given as continuous infusion – Rate of PG infusion exceeds FDA guidelines when MEL bolus given currently CE-Melphalan (Propylene Glycol-free) • FDA Approved March 2016 – 1st drug to gain FDA approval for the high-dose conditioning indication in MM • Captisol-enabled melphalan (CE-melphalan) approved for two indications in MM – High-dose conditioning treatment prior to HSCT for patients with MM – Palliative treatment for MM patients who are not candidates for oral therapy • Approval based on multicenter, open-label, phase 2b study of 61 patients (5 relapsed prior to HSCT; 56 with newly diagnosed disease)1 – 200 mg/m² CE-melphalan, administered in 100 mg/m² doses on day 3 and day 2 before transplantation – ORR:95%; CR: 31% (16% stringent CRs) [as determined by investigator assessment] – No treatment-related mortality; no new safety signals 1.

Biol Blood Marrow Transplant. 2015;21:2100-2105. 44 CE-Melphalan (Propylene Glycol-free): Phase 2a Pharmacokinetic Study Results from the Phase 2a study (N=24) • CE-Melphalan is bioequivalent to standard Melphalan – Propylene glycol-free – More stable following reconstitution – Longer infusion times / higher doses possible with CE-Melphalan (propylene glycol-free) could improve response to treatment • The efficacy and safety profile were consistent with that already established for high-dose Melphalan conditioning with ASCT for MM – 100% of patients achieved myeloablation and engraftment – Most frequent AEs included fatigue, nausea, and hypokalemia Aljitawi, et al.
