E.4 | Principal exclusion criteria |
1.Diagnosis of Fanconi anemia.
2.Evidence of a clonal hematologic bone marrow disorder on cytogenetics. Patients with very severe neutropenia (ANC < 200 /μL) will not be excluded initially if cytogenetics are not available or pending. If a clonal disorder is identified, the patient will be excluded.
3.Prior immunosuppressive therapy with cyclosporine, alemtuzumab, rabbit or horse ATG and thrombopoietin receptor (TPO-R) agonists.
4. a. Hypersensitivity to eltrombopag or cyclopsorine or their components.
b. Contraindications to cyclosporine
5.AST or ALT >3 x ULN.
6.Serum creatinine, total bilirubin, and alkaline phosphatase >1.5 x ULN .
7.Patient with liver cirrhosis.
8.Infection not adequately controlled with appropriate therapy.
9.Moribund status or concurrent hepatic, renal, cardiac, neurologic, pulmonary, infectious, or metabolic disease of such severity that it would preclude the patient’s ability to consent, be compliant with study procedures, tolerate protocol therapy, or that death within 30 days is likely.
10.Patients with cancer who are not considered cure, are on active chemotherapeutic treatment or who take drugs with hematological effects.
11.Administration of an investigational drug within 30 days or 5 half-lives, whichever is longer, preceding the first dose of study treatment.
12.Pregnancy statements and contraception requirements:
Pregnancy or nursing (lactating) women
Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant (or female partners of male patients), unless they are using highly effective methods of contraception during dosing and for 3 months after stopping medication.
In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment.
13.Not able to understand the investigation nature of the study or to give informed consent.
14.Clinically significant ECG abnormality including cardiac arrhythmias (e. g. ventricular tachycardia) complete left bundle branch block, high grade atrioventricular block, or inability to determine the QTcF interval on the ECG.
15.Presence of cardiac disease, or family history of idiopathic sudden death or congenital long QT syndrome.
16.Risk factors for Torsades de Pointe including uncorrected hypokalemia or hypomagnesemia, or use of concomitant medication(s) with a known risk to prolong the QT interval that cannot be discontinued or replaced by safe alternative medication per www.qtdrugs.org. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary objective of the study is to evaluate the eltrombopag + cyclosporine as first-line therapy as assessed by the overall hematologic response rate by 6 months. Bayesian approach will be used for analysis of the primary endpoint. The primary analysis will be based on the calculation of observed overall hematologic response rate by 6 months and its posterior distribution using a beta-binomial model. Combination therapy of eltrombopag + cyclosporine will be declared efficacious if the following criteria are met:
a. Observed hematologic ORR ≥ “clinically meaningful” threshold (30%)
b. Probability of true ORR “not being clinically meaningful (response ≤ 20%) is less than 10%.

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Overall hematologic response rate by 6 months |
|
E.5.2 | Secondary end point(s) |
Second analysis will be done after all the patients enrolled have completed 30 months of treatment with cyclosporine or discontinued treatment with cyclosporine prior to 30 months. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
hematologic response rate by 3 months and at 12 months |
