Outcomes

Primary Outcome Measures

Number of Participants With Overall Induced Mucinous Glycoprotein-1 (MUC-1)-Specific Immune Response
The overall immune response was achieved at least for 2 timepoints; that is at least 1 parameter in at least 1 assay (Lymphoproliferation assay, enzyme-linked immunospot (ELISPOT) for interferon [IFN] gamma, and intracellular IFN gamma cytokine assay in peripheral blood mononuclear cell [PBMC]) with ratio to background >=2, and ratio of background-corrected value to baseline >=2;Specific immune response at a given timepoint 't' was considered as differences of log-scale values under stimulation (X vax,t ) to those of the respective unstimulated controls (Xneg,t, background values)were computed after certain assay-specific pre-processing steps: Yt = Xvax,t - Xneg,t; A participant was considered to show positive stimulation-induced immune response at timepoint 't' (POS[t]=1), upon fulfilling the following criteria: Yt =>1 (That is at least a 2-fold higher value under stimulation than without stimulation). AVvax,t-1SEM vax,t > AVneg,t+1SEMneg,t (ELISPOT and proliferation assay only).

Secondary Outcome Measures

Number of Participants With Baseline Immune Response and Initial Increase of MUC1 Specific Immune Response
Baseline immune response towards MUC1 was defined as an immune response towards BP25, MUC-A2 or MUC-A11 peptide stimulation which was present in at least one of the two baseline assessments; the specific immune responses at baseline were based on the averaged baseline values across the two baseline visits. Initial increase of MUC1-specific immune response was defined as an increase of MUC1-specific immune response during the primary treatment period (up to Week 9).
Number of Participants With Overall Induced Immune Response by Human Leukocyte-associated Antigen (HLA) Type
Relationship between immune response with HLA subtypes was determined by analyzing the number of participants with overall induced immune response grouped by the presence versus absence of the given HLA type.
Percentage of Participants With Objective Clinical Response (Complete Response [CR], or Partial Response [PR], or Minimal Response [MR]
OCR (CR, or PR, or MR or NC or PD or NE) was defined per Blade Criteria. OCR rate (CR, or PR, or MR) was defined as the number of participants having experienced at least once a CR, PR, or MR, divided by the number of all participants. CR: negative immunofixation on serum and urine monoclonal paraprotein (M-protein), disappearance of any soft tissue plasmacytomas (STP), <=5% plasma cells in bone marrow (BM); PR: >=50% reduction in serum M-protein, plasma cells in BM, size of STP; >=90% reduction of urinary M-protein in 24 hours, no increase in size/number of the lytic bone lesions (LBL). MR: 25%-49% reduction in serum M-protein, plasma cells in BM aspirate in non-secretory myeloma participants, size of STP; 50%-89% reduction in 24 h urinary light chain reaction (LCR), and no increase in size/number of LBL. PD: >25% increase in the serum M-protein level, 24 hour urinary LCR. Increase in size of existing BL or STP, development of new BL or STP, or development of hypercalcemia
Time to Progression (TTP)
Progression was defined as follows per Blade criteria: The disease was considered to be progressive if it met 1 or more of the following: >25% increase in the level of serum monoclonal paraprotein (M-protein);>25% increase in the 24 h urinary light chain excretion; >25% increase in plasma cells in the bone marrow- definite increase in the size of existing bone lesions or soft tissues plasmacytomas (STP); Development of new bone lesions or STP, or development of hypercalcemia. TTP was defined as time from randomization to disease progression. Participants without events were censored on the date of last tumor assessment. Participants without PD at time of treatment discontinuation were censored at the date of discontinuation. Participants without PD at the time of the analysis but still on treatment were censored at the date of the latest available multiple myeloma status assessment. Participants dying from causes other than PD were treated as censored observations at time of death.
Time to Anti-tumor Therapy
Time from date of randomization to the date of first anti-tumor therapy since end of study treatment. In case a concomitant or concurrent procedure was identified as anti-tumor therapy during the medical review process, the start date of that anti-tumor therapy was used instead. Participants in the survival follow-up phase without subsequent anti-tumor therapy at the time of the analysis were censored at the latest available follow-up date. Participants without anti-tumor therapy and still on treatment at the time of analysis were censored at the data cut-off date if any trial treatment administration was recorded after the data cut-off date. In case no such record exists, the subject was censored at the last available administration date prior or equal to the data cut-off date. Participants dying before start of subsequent anti-tumor therapy were treated as censored observations at time of death.
Number of Participants With Treatment Emergent Adverse Events (TEAEs),Serious TEAEs, TEAEs of Grade 3 or 4 According to NCI-CTCAE v3.0, TEAEs Leading to Discontinuation and Injection Site Reactions (ISRs)
TEAEs occurred between the first dose of study drug administration and up to 42 days after the last dose of study drug administration that were absent before treatment or that worsened relative to pretreatment state. A Serious TEAE was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect.Grade 3 and 4 TEAES as per National Cancer Institute Common Terminology Criteria for Adverse Experience version 3 (NCI-CTCAE v3.0) were presented. Grade 3 refers to severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care and Activity of daily living (ADL).Grade 4 refers to Life-threatening consequences; where urgent intervention indicated. Injection site reactions, term used per NCI-CTCAE, were also presented.

Tecemotide (L-BLP25) is believed to induce a Mucinous glycoprotein 1 (MUC1)-specific T-cell response after vaccination. The primary purpose of this study is to ascertain whether vaccination with tecemotide (L-BLP25) induces a MUC1-specific T-cell response in slowly progressive or chemotherapy naive multiple myeloma subjects.
