Brief summary

The purpose of this study is to evaluate the anti-tumor activity, safety and pharmacology of two dose regimens (0.2 and 2 mg/kg)of IPH2101 in patients with Smoldering Multiple Myeloma.

Detailed description

This is a randomized Phase II, open label, multi-centre study, with two independent arms. Patients receive 6 injections of IPH2101, at the dose of 0.2 mg/kg or 2 mg/kg (according to their randomization) administered over one hour infusion at four weeks intervals. A patient whose disease achieves at least a minimal response to study treatment at any time during the initial period of 6 cycles can be treated with an additional period of treatment of 6 cycles. Patients are followed 6 months after treatment completion or until a KIR occupancy level \< 30% (i.e if the time required for KIR desaturation was \> 6 months), whichever is longer.

Interventions

0.2 mg/Kg or 2mg/Kg, every 4 weeks by intravenous route over 1 hour, for 6 or up to 12 cycles
