Brief Summary:
The trial is a multi-centre, open-label, safety and tolerability extension trial to the IPH2101-101 (previously NN1975-1733) first human dose trial completed with a larger subject pool at an optimal dose level. The trial is conducted in elderly Acute Myeloid Leukemia (AML) patients over the age of 60 years, in complete remission, and who are not eligible for allogeneic stem-cell transplantation. The dose given to the individual patient will be the same as the patient received in the single dose trial IPH2101-101 and 1 mg/kg or 2 mg/kg for the 12 patients in an additional cohort.

Condition or disease Intervention/treatment Phase

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 21 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-label, Safety and Tolerability Extension Trial Assessing Repeated Dosing of Anti-KIR (1-7F9) Human Monoclonal Antibody in Patients With Acute Myeloid Leukaemia
Study Start Date : February 2007
Actual Primary Completion Date : July 2013
Actual Study Completion Date : September 2013

Arm Intervention/treatment
Experimental: IPH2101 Drug: IPH2101
IPH2101 fully human anti-KIR monoclonal antibody

Primary Outcome Measures :
  1. To assess safety and tolerability of repeating dosings of Anti-KIR(1-7F9) [ Time Frame: every 2 weeks ]
    using the US National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE)

Secondary Outcome Measures :
  1. To assess the pharmacokinetics upon repeated dosing(s)of Anti-KIR(1-7F9) [ Time Frame: every 2 weeks ]
  2. To assess the pharmacodynamics upon repeated dosing(s) of Anti-KIR(1-7F9) [ Time Frame: every 2 or 4 weeks ]
    • Degree of KIR-occupancy on patient NK-cells
    • Plasma inflammatory cytokines (IFN-γ, TNF-α, IL-1, IL-6)
    • Immunophenotyping (NK-, B- and T-lymphocyte counts and activation status)
    • NK-cell surface markers (activation markers and inhibitory receptors)
    • Functional assay of NK-cell activity only for patient from additional cohort

  3. To assess signs of efficacy of repeated dosing(s) with Anti-KIR(1-7F9) [ Time Frame: to date of progression diagnosed or until death ]
    • Reduction in minimal residual disease measured by WT-1 expression in blood and bone marrow
    • Progression-free survival (measured as calendar days from the first dosing of Anti-KIR(1-7F9) (in the IPH2101-101 trial) to date of progression diagnosed or until death by any cause
    • Overall survival measured as calendar days from the first dosing of Anti-KIR (1-7F9) to date of death
