E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Idiopathic (Severe) Aplastic Anemia, a bone marrow failure syndrome which results in the normal hematopoietic tissue completely missing from the bone marrow, accounting for the subsequent pancytopenia. |
|
E.1.1.1 | Medical condition in easily understood language |
Severe aplastic anemia is an hematological disease of the bone marrow resulting in pancytopenia, a medical condition where there is a reduction in numbers of red-, white blood cells and platelets. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1.Diagnosis of severe or very severe aplastic anemia, defined by • At least two of the following: – Absolute neutrophil counts <0.5 x 10(9)/L (severe) or <0.2 x 10(9)/L (very severe) – Platelet counts <20 x 10(9)/L – Reticulocyte counts <60 x 10(9)/L • Hypocellular bone marrow (<30% cellularity), without evidences of fibrosis or malignant cells 2.Age ≥ 15 years; 3.Written informed consent
|
|
E.4 | Principal exclusion criteria |
1.Prior immunosuppressive therapy with ATG (horse of rabbit) or any other lymphocyte depleting agent (i.e., alemtuzumab)
2.Eligibility to a sibling allogeneic stem cell transplantation
3.Evidence of a myelodysplastic syndrome, defined by the presence of myelodysplastic features, excess of blasts or karyotypic abnormalities typical of MDS (according to revised WHO 2008 criteria) , as well as other primitive marrow disease. Patients with diagnosis of AA with cytogenetic abnormalities which are recurrent in MDS (according to revised WHO 2008 criteria) should be included in this category, and are not eligible for the study; patients with del(20q), +8 and –Y are not included in this category, and thus are eligible for this study. The list of karyotypic abnormalities which qualifies for the diagnosis of MDS are listed in the Appendix 1.
4.History or clinical suspect of constitutional aplastic anemia (i.e. Fanconi Anemia with positive DEB/MMC test or Dyskeratosis Congenita)
5.History of malignant tumors with active disease within 5 years from enrollment and/or previous chemo-rediotherapy
6.Previous history of stem cell transplantation
7.Treatment with cyclosporin: • <4 weeks of cyclosporin A treatment before enrollment. • Wash out period of 2 weeks before enrollment.
8.CMV viremia, as defined by positive PCR or pp65 test
9.WHO performance status ≥3
10.Pregnant or breast feeding patients
11.Patients with hepatic, renal or cardiac failure, or any other life- threatening concurrent disease
12.Patients with HIV infection
13.Patients without social health care assistance
14.Participation in another clinical trial within 1 month before the start of this trial
15.Subjects with known hypersensitivity to any of the component medications

E.5 End points |
E.5.1 | Primary end point(s) |
Rate of Complete response (defined as Hb >10 g/dL, ANC > 1,000/μL and Plt >100,000 μL) at 3 months since start of treatment in untreated severe AA patients. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
For the main endpoint a valid response has to be measured between month 3 plus or minus 10 days; in case of more than one measurement available in this time period, the best response will be taken. |
|
E.5.2 | Secondary end point(s) |
1.Time to first hematological response (complete or partial) described by a cumulative incidence curve (see paragraph 9.6)
2.Time to best hematological response, described by a cumulative incidence curve (see paragraph 9.6)
3.Time to complete response (see paragraph 9.6)
4.Rates of hematological response (overall, complete, partial) at 6, 12, 18 and 24 months
5.Overall survival (OS) probability; OS is defined as time from treatment starting (day 1) to death, or last follow-up for patients alive
6.Event-free survival (EFS) probability; EFS is defined as time from treatment starting to either relapse, death, treatment failure or clonal evolution (whichever occurs first), or last follow-up for patients alive in response
7.Cumulative incidence of relapse, from first hematological response (complete or partial) (see paragraph 9.6)
8.Cumulative incidence of clonal evolution (as defined below, see 9.5): AML, MDS or karyotypic abnormalities (see paragraph 9.6)
9.Cumulative incidence of PNH population occurrence and clinical hemolytic PNH occurrence (see paragraph 9.6)
10.Cumulative incidence of discontinuation of immunosuppressive therapy
11.Rate of CsA-independent hematological response at 24 months
12.Need for transfusions (packed red cell units and platelet units) and number of transfusions required from treatment.
13.Need for any supportive care, including hospitalization
14.Quality of life (as assessed by the validated EORTC QLQ-C30 questionnaire)(changes over time and differences between treatment arms)
15.Safety and tolerability of the investigational treatment, including SAE
