Brief Summary:
This study will determine the Maximal Tolerated Dose if any and the recommended dose for phase 2 of monalizumab, a monoclonal antibody directed against the CD94/NKG2A receptor, after allogenic stem cell transplantation. All patients will receive one single intravenous administration of one of the four doses of monalizumab.

Condition or disease Intervention/treatment Phase
Hematologic Malignancies Drug: Monalizumab Phase 1

Detailed Description:

Allogeneic hematopoietic stem cell transplantation (Allo-HSCT) is a curative option for most of hematological malignancies, though the graft-versus-tumor (GVT) effect mediated by immune cells from the donor. However, the use of Allo-HSCT is limited by its toxicity, notably the graft-versus-host disease (GVHD) that is a major cause of non-relapse mortality (NRM). Conditioning regimens dramatically improved during the last fifteen years, with a decrease of both GVHD and NRM rates. Now, disease recurrence after Allo-HSCT is the first cause of treatment failure and remains a concern for approximately 30% of the patients.

Based on a safety immunologic platform (ATG based reduced toxicity conditioning regimens), it is needed to develop post Allo-HSCT strategies to decrease the incidence of relapse. In this context, the modulation of immune cell activity could play a role to prevent relapse. NK cells have a unique capacity to exert potent GVT effects without inducing GVHD. Moreover, NK cells recovery occurs early after Allo-HSCT and NK cells function are not severely impaired by the use of ciclosporin A, that is given for few months after Allo-HSCT as GVHD prophylaxis. Thus, NK cell modulation appears as a viable option for early immune intervention after Allo-HSCT.

Monalizumab (IPH2201), a monoclonal antibody has a non-depleting and purely blocking activity directed with high affinity and specificity against the CD94/NKG2A receptor expressed by subsets of NK cells, activated αβ CD8+ T cells, γδ-T cells and NK T cells. By suppressing the inhibitory signal transduced by NKG2A, IPH2201 enhances the anti-tumor functions, including cytolytic activity of these immune effector cells.The aim of the study is to determine the safety of IPH2201 after allogenic stem cell transplantation.

Estimated Study Completion Date : April 28, 2020

Arm Intervention/treatment
Experimental: Monalizumab
Monalizumab treatment will be initiated 75 to 100 days after hematopoietic stem cells transplantation. Patients will receive a single dose of monalizumab by intravenous route over 1 hour.
Drug: Monalizumab
Four dose levels will be tested.
Other Names:
  • anti CD94/NKG2A
  • IPH2201




Primary Outcome Measures :
  1. Occurence ratio of dose-limiting toxicity (DLT) [ Time Frame: 4 weeks ]

    The occurrence of any of these 3 events will lead to the reporting of a Dose Limiting Toxicity:

    • Any Grade ≥ 3 toxicity according to CTCAE attributable to IPH2201 administration, occurring within 4 weeks of IPH2201 administration and considered as relevant by the investigator
    • Any grade ≥ II acute GVHD requiring a treatment by systemic corticosteroids and occurring within 4 weeks of IPH2201 administration.
    • Any grade ≥ moderate chronic GVHD occurring within 4 weeks of IPH2201 administration.


Secondary Outcome Measures :
  1. Incidence of acute GVHD of each grade or chronic GVHD of each degree of severity [ Time Frame: from D0 to Week 26 after administration of IPH2201 and at 1 year after transplantation ]
    Safety will be assessed using Glucksberg's classification for acute Graft versus host disease (GVHD) and NIH classification for chronic GVHD.

  2. Probabilities of non-relapse mortality (NRM) [ Time Frame: 1 year after the administration of IPH2201 ]
  3. Cumulative incidence of relapse (CIR) [ Time Frame: 1 year after administration of IPH2201. ]
    Efficacy endpoint

  4. Probability of Disease Free Survival (DFS) [ Time Frame: 1 year after the administration of IPH2201 ]
    Efficacy endpoint

  5. Probability of Overall survival (OS) [ Time Frame: 1 year after the administration of IPH2201 ]
    Efficacy endpoint
