A clinical gene therapy study with hematopoietic stem cells for the treatment of patients suffering from a plasma cell tumor.

A phase I/II dose escalation study evaluating safety and activity of autologous CD34+-enriched hematopoietic progenitor cells genetically modified with a lentiviral vector encoding for the human interferon-alfa2 gene in multiple myeloma patients with early relapse after intensive front line therapy - TEM-MM

Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate safety and tolerability of escalating doses of Temferon in multiple myeloma patients with early relapse after intensive front line therapy.;Secondary Objective: To evaluate biological activity and efficacy of escalating doses of Temferon as maintenance/consolidation treatment in multiple myeloma patients with early relapse after intensive front line therapy.;Primary end point(s): - Engraftment of Temferon after reduced intensity conditioning (vector copy number [VCN] > 0.07 in myeloid cells between Day +30 and Day +100 in at least 2 patients); - The proportion of patients achieving hematologic recovery by Day +30 from ASCT with non-manipulated autologous HSPC and infusion of Temferon; - Safety of Temferon measured through the 24 months post Temferon infusion.;Timepoint(s) of evaluation of this end point: Multiple timepoints up to 2 years

Secondary

MeasureTime frame
Secondary end point(s): - Presence of an IFN-alfa gene signature in the bone marrow (BM) of Temferon-treated patients. - Presence of transduced myeloid cells in BM aspirate and peripheral blood (PB) at Day +30 and Day +100 post Temferon infusion as determined by VCN. - Persistence of transduced myeloid cells in PB and BM as assessed by VCN for at least 12 weeks - Overall response rate (ORR) - Fraction of patients achieving complete response (CR) with minimal residual disease (MRD) levels = 10-5 and 10-6 on BM aspirate - Duration of maintenance of response during the 24 months post Temferon infusion - Progression-free survival (PFS) and overall survival (OS) at 24 months post Temferon infusion. - Change in health-related quality of life (HRQOL) at 6, 12 and 24 months post Temferon infusion compared to screening. - Change over time in performance status scores (ECOG and Karnofsky) through 24 months post Temferon infusion.;Timepoint(s) of evaluation of this end point: Multiple timepoints up to 2 years
