Last Updated: 2021-04-09

Results Overview

Number of participants with each disease response category utilizing the Blade criteria: * Complete Response (CR): Defined as negative serum and urine immunofixation and a bone marrow aspirate with \< 5% plasma cells. * Near Complete Response (nCR): Defined as negative serum and urine paraprotein, positive serum and/or urine immunofixation, and a bone marrow aspirate with \< 5% plasma cells. * Very Good Partial Response (VGPR): Defined as negative serum and urine paraprotein with positive serum and/or urine immunofixation; or a 90% decrease in serum paraprotein with urine paraprotein \< 100 mg/24 hours. * Partial Response (PR): Defined as a 50-89% decrease in serum paraprotein. * Minimal Response (MR): Defined as a 25-49% decrease in serum paraprotein. * Stable Disease (SD): Defined as not falling into any other response category. * Overall response rate (ORR): Total of CR, nCR, VGPR, and PR.

Measure
ASCT + MILs
Cyclophosphamide and filgrastim will be given to mobilize peripheral blood stem cells. Leukapheresis will be performed to collect peripheral blood from which activated marrow infiltrating lymphocytes will be produced. A melphalan conditioning regimen will be used prior to autologous stem cell transplant, and the MILs product will be administered on Days 3 and 4. Activated marrow infiltrating lymphocytes: Administered on Days 3 and 4. Cyclophosphamide: Administered at 2.5 g/m\^2. Filgrastim: Administered post cyclophosphamide daily until leukapheresis. Leukapheresis: Performed approximately 12 days post cyclophosphamide. Exact date depends on peripheral blood CD34+ cell counts. Melphalan: 100 mg/m\^2/day given on Days -2 and -1. Autologous stem cell transplant: Infused on Day 0.

PRIMARY outcome

Timeframe: Up to 1 year

Population: Only participants who had ASCT were evaluated for response. Three participants on the ASCT + MILs arm and two participants on the ASCT + MILs + vaccine arm were removed from study prior to ASCT and were therefore not evaluable for this outcome.

Number of participants with each disease response category utilizing the Blade criteria: * Complete Response (CR): Defined as negative serum and urine immunofixation and a bone marrow aspirate with \< 5% plasma cells. * Near Complete Response (nCR): Defined as negative serum and urine paraprotein, positive serum and/or urine immunofixation, and a bone marrow aspirate with \< 5% plasma cells. * Very Good Partial Response (VGPR): Defined as negative serum and urine paraprotein with positive serum and/or urine immunofixation; or a 90% decrease in serum paraprotein with urine paraprotein \< 100 mg/24 hours. * Partial Response (PR): Defined as a 50-89% decrease in serum paraprotein. * Minimal Response (MR): Defined as a 25-49% decrease in serum paraprotein. * Stable Disease (SD): Defined as not falling into any other response category. * Overall response rate (ORR): Total of CR, nCR, VGPR, and PR.
