Phase I: The primary purpose of this study phase is to determine the best dose also referred to as the maximum tolerated dose (MTD) of Selinexor when used in combination with high-dose melphalan as a conditioning regimen for hematopoietic cell transplant.
Phase II: The primary purpose of this study phase is to assess the complete response (CR) conversion rate.

|Official Title:||Phase 1/2 Investigator Sponsored Study of Selinexor in Combination With High-Dose Melphalan Before Autologous Hematopoietic Cell Transplantation for Multiple Myeloma|

|Estimated Study Completion Date :||August 31, 2022|
Experimental: Selinexor Plus HDM HCT
The conditioning regimen begins 3 days prior to autologous transplant. Day 0 is the day of the autologous hematopoietic cell transplant. Melphalan will be given intravenously (IV) on Day -3 and Day -2; Dexamethasone will be given through via IV on Day -3, Day -2 and Day -1; fosaprepitant at 150 IV on days -3 and -2 will be given to patients an an antiemetic.Selinexor will be taken by mouth (PO) daily on the same day participants receive chemotherapy with melphalan.
Selinexor will be given orally 2 to 3 hours prior to high dose-melphalan IV infusion. Phase I: Dose escalation beginning with 40 mg to determine the recommended Phase II dose (RPh2D). Phase II: Treatment at RPh2D.
Other Name: KPT-330
Melphalan 100 mg/m^2 IV over 30-45 minutes.
Other Name: Alkeran
Dexamethasone 20 mg PO (or IV) daily (on days -3, -2 and -1).
Other Name: Decadron
Procedure: Autologous Hematopoietic Cell Transplantation (HCT)
Participant's own stem cells are collected from their blood, frozen, then given back to them after chemotherapy.
Fosaprepitant at 150 mg IV on days -3 and -2.
- Phase I: Recommended Phase II Dose (RPh2D) [ Time Frame: Up to 3 months ]RPh2D/Maximum Tolerated Dose (MTD) of Selinexor when used in combination with high-dose melphalan as a conditioning regimen for hematopoietic cell transplant. MTD: the highest dose level at which 1 or less of 6 participants experience a dose limiting toxicity (DLT).
- Phase II: Complete Response (CR) [ Time Frame: 3 months post HCT ]
Complete response (CR) conversion rate. CR: Negative immunofixation of serum and urine, disappearance of any soft tissue plasmacytomas, and ≤ 5% plasma cells in bone marrow.
tissue plasmacytomas, and ≤ 5% plasma cells in bone marrow.
Complete Response conversion rate. CR: Negative immunofixation of serum and urine, disappearance of any soft tissue plasmacytomas, and ≤ 5% plasma cells in bone marrow.
- Progression Free Survival (PFS) [ Time Frame: 3 months post HCT ]Progressive Disease (PD) as outlined by International Myeloma Working Group (IMWG) uniform response criteria by response subcategory for multiple myeloma.
- Overall Survival (OS) [ Time Frame: 3 months post HCT ]Rate of participants' survival at time of evaluation.
- Rate of Minimal Residual Disease (MRD) [ Time Frame: 3 months post HCT ]To assess minimal residual disease (MRD) with PET scan, bone marrow flow cytometry and/or immunoglobulin gene sequencing at 3 months after autologous HCT (exploratory endpoint).
