Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The aim of the phase IIa trial is to investigate the rate of response in patients with high risk smoldering multiple myeloma vaccinated with PD-L1 long1.;Secondary Objective: Furthermore, immunogenicity of the vaccine, adverse events, quality of life, time to progression and overall survival will be described.;Primary end point(s): • Overall response rate (ORR);Timepoint(s) of evaluation of this end point: Three months after last vaccination | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Immunogenicity of the vaccine (blood and bone marrow) • Incidence of treatment emergent adverse events (TEAE) and patient reported outcomes (PRO) in terms of quality of life (QoL) as well as patient reported adverse events (PRO-CTCAE) • Progression-free survival (PFS) • Time to progression (TTP) • Overall survival (OS) ;Timepoint(s) of evaluation of this end point: Analysis of Immunogenicity, PRO and Adverse events will be performed when the latest enrolled patient has been followed three months after last given vaccine. Analysis of TTP, PFS and OS will be performed at two time points of 48 months and 5 years from the inclusion of the latest enrolled patient. | — |
