Brief Summary:
This is a phase II exploratory study conducted to evaluate the safety and efficacy of the combination of Ibuprofen, G-CSF and Plerixafor as stem cell mobilization regimen in patients affected by X-CGD.

Condition or disease Intervention/treatment Phase
Chronic Granulomatous Disease X-linked (X-CGD) Drug: Ibuprofen Drug: Myelostim Drug: Mozobil Phase 2

Detailed Description:

We designed a mobilization trial with the aim of collecting a sufficient number of HSPC in X-CGD patients; it is well known that this procedure is challenging for these patients, potentially due to functional defects induced by their chronic inflammatory state.

The combination of G-CSF and Plerixafor is considered state of the art for HSPC harvest in gene therapy trials; we considered to add a non-steroidal inflammatory drug to increase HSPC mobilization and reduce inflammation that could have a role in altering HSPC content.

If this trial confirms the synergistic effect of the three drugs under investigation, such a regimen will be considered for a HSPC mobilization in future gene therapy trial for X-CGD patients.

Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: A Multicentric, Exploratory, Non-randomised, Non-controlled, Prospective, Open-label Phase II Study Evaluating Safety and Efficacy of IBU, G-CSF and Plerixafor as Stem Cell Mobilization Regimen in Patients Affected by X-CGD
Study Start Date : November 2015
Estimated Primary Completion Date : September 2017
Estimated Study Completion Date : August 2018

Arm Intervention/treatment
Experimental: XCGD mobilization
Treatment with combination of Ibuprofen, Myelostim and Mozobil
Drug: Ibuprofen
Ibuprofen: 3 mg/kg tid (total daily dose: 9 mg/kg); administered orally from day 1 to day 5 and then from day 14 to the day before the last LP.

Drug: Myelostim
Myelostim (G-CSF): 5 µg/kg bid (total daily dose 10 µg/kg); administered subcutaneously from day 19 to the day of the last LP.

Drug: Mozobil
Mozobil (Plerixafor): 0,24 mg/kg daily. When CD34+ are ≥ 10 /μL Plerixafor will be administered subcutaneously from the next day (or from day 24 if CD34+ are < 10 /μL) to the day of the last LP.

Primary Outcome Measures :
  1. Percentage of patients experiencing adverse events [ Time Frame: up to 30 days after the last LP ]
    Percentage of patients experiencing adverse events, as assessed by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse events (CTCAe v3.0, 2006) (all grades).

  2. Number of CD34+ collected per body weight after the last LP [ Time Frame: Day 21-24 ]
    Cytofluorimetric analysis for CD34 on PB and on collected PBSC to calculate the number of CD34+ cells collected per kg body weight. The analysis will be performed at the end of the LP(s) (Day 21-24)

Secondary Outcome Measures :
  1. Change in number of CD34+ cells in PB before and after administration of Ibuprofen [ Time Frame: Day 6 and day 7 ]
    Cytofluorimetric analysis to determine the number of CD34+ cells present in PB on day 6 and 7 compared to before the administration of Ibuprofen

  2. Transduction efficiency [ Time Frame: Through study completion, an average of 1 year ]
    Efficient transduction of mobilized HSPC with a lentiviral vector encoding for a corrective cDNA of the human gp91phox gene. Frequency and Vector Copy Number tested by PCR.

  3. DHR (dihydrorhodamine) test in myeloid progeny [ Time Frame: Through study completion, an average of 1 year ]
    Correction of the functional defects in the differentiated myeloid progeny

  4. Functional characterization of mobilized CD34+ cells. [ Time Frame: Through study completion, an average of 1 year ]
    Phenotype analysis (FACS).

  5. Functional characterization of mobilized CD34+ cells. [ Time Frame: Through study completion, an average of 1 year ]
    Clonogenic activity (CFU-C) before and after transduction.

  6. Functional characterization of mobilized CD34+ cells. [ Time Frame: Through study completion, an average of 1 year ]
    Repopulating activity of mobilized CD34+ cells in immunodeficient mice.
