Summary:

      This is an open randomised phase II study evaluating the anti-tumour activity, safety and
      pharmacology of two dose regimens of IPH2101, a human monoclonal anti-KIR antibody, in
      patients with multiple myeloma in stable partial response after a first line therapy.
    

Eligibility criteria:

        Inclusion Criteria:

          1. MM which initially required a systemic therapy and received a first line treatment,
             conventional doses of chemotherapies or high dose chemotherapy and an autologous
             transplantation of hematopoietic cells, followed or not by a consolidation treatment.

          2. Residual disease considered as evaluable with:

               -  Quantifiable serum M-protein: ≥ 3 g/l, except for spike in the beta globulin
                  area. In this particular case serum M-protein is considered quantifiable if ≥
                  10g/l

               -  If serum M-protein is < 3g/l, measurable involved Free Light Chains ≥ 100 mg/l
                  and an abnormal Free Light chains ratio (<0.26 or > 1.65)

          3. Responses which are partial (PR and VGPR) and in plateau

               -  Partial response should meet the IMWG uniform response criteria: a ≥ 50%
                  reduction from value of serum M-protein before the first line chemotherapy
                  treatment and a reduction in 24h urinary M-protein by ≥ 90% or to < 200 mg /24h;

               -  Very good partial response according to the IMWG uniform response criteria with
                  90% or greater reduction in serum M-protein plus urine M-protein level < 100
                  mg/24h; furthermore the M-protein should spike in the gamma globulin area;

               -  Plateau phase is defined by :

                    -  For patients with serum M-protein ≥ 3g/l: stable levels of M-protein in
                       serum during at least 2 months checked on at least 3 consecutive samples,
                       with the third evaluation performed within 4 weeks before study entry.
                       Fluctuations of ± 25 % and ± 2 g/l in Serum M-protein levels are allowed.

                    -  For Patients with serum M-protein < 3g/l: stable levels Free Light Chains in
                       serum during at least 2 months checked on at least 3 consecutive samples,
                       with the third evaluation performed within 4 weeks before study entry.
                       Fluctuations of ± 25 % of involved serum Free Light Chain are allowed.

          4. ECOG performance status of 0, 1 or 2.

          5. Clinical laboratory values at screening:

               -  Calculated creatinine clearance (according to MDRD) > 50 ml/min

               -  Platelet > 50 x 109 /l

               -  ANC > 1 x 109 /l

               -  Bilirubin levels < 1.5 ULN; ALT and AST < 2.5 ULN

          6. Male or female patient who accepts and is able to use recognised effective
             contraception (oral contraceptives, IUCD, barrier method of contraception in
             conjunction with spermicidal jelly) throughout the study.

          7. Signed inform consent obtained before any trial-related activities

        Exclusion Criteria:

          1. Age < 18 years old or > 75 years old

          2. Previous consolidation/ maintenance therapy by Imid (thalidomide, lenalidomid) or
             bortezomib within the last 2 months

          3. Treatment with chemotherapy, systemic corticosteroid within the previous 2 months

          4. Treatment with growth factors (EPO, G- or GM-CSF) within the previous 1 month

          5. Radiotherapy for bone or visceral lesion within the last 3 months

          6. Use of any investigational agent within the last 2 months

          7. Primary or associated amyloidosis

               2. myocardial infarction within the previous 6 months

               3. symptomatic cardiac arrhythmia despite treatment

         10. Current active infectious disease or positive serology for HIV, HCV or positive Hbs
