  • 1. Able to provide written informed consent and agreeable to the schedule of assessments
  • 2. Male or female subjects, aged 18 years or older
  • 3. Diagnosis of primary ITP (persistent or chronic) made according to the American Society of Hematology 2011 evidence-based guideline
  • 4. Failed to respond or relapsed after at least 1 prior therapy, with a platelet count of <30,000/µL on 2 occasions at least 7 days apart with the confirmatory count on the first day of treatment. Response to such prior therapy is defined as platelet count of =30,000/µL and >2 times increase from baseline in the absence of bleeding. Failure to respond and relapse to such prior therapy are defined as failure to achieve and/or failure to maintain response on a tolerable regiment of prior therapy.
  • 5. Adequate hematologic, hepatic, and renal function (absolute neutrophil count = 1.5 X 109/L, hemoglobin [Hgb] = 10.0 g/dL, aspartate aminotransferase [AST] and alanine aminotransferase [ALT] = 2.0 x ULN, bilirubin <1.5 x ULN, albumin = 3 g/dL, estimated glomerular filtration rate [eGFR] =40 mL/min/1.73m2, and creatinine = 1.5 x ULN)
  • 6. ECOG performance status of 0, 1, or 2
  • 7. Both male and female subjects must agree to take the following steps to reduce the potential for transmission of genetic material containing the investigational product
  • a. Both male and female subjects, the subject and their partners of
  • childbearing potential must agree to use 2 of the following medically acceptable methods of contraception from the time of randomization, during the study, and for 6 months following discontinuation of study drug, of which:
  • o One must be a highly reliable method of contraception, such as:
  • ? An intrauterine device or intrauterine system implanted for at least 30 days prior to Day 1
  • ? Surgical sterilization of one of the partners for at least 6 months prior to the date of informed consent (assuming this will be the only partner for the whole duration of the clinical trial)
  • ? Consistent and correct use of hormonal contraceptives (hormonal implants, injectables, contraception pills, transdermal patches, or contraceptive rings) for at least 30 days prior to Day 1
  • o One supplementary barrier method, such as:
  • ? Male or female condom always with spermicide (a spermicidal
  • foam/gel/film/cream)
  • ? Diaphragm or cervical/vault caps always with spermicide (a
  • spermicidal foam/gel/film/cream)
  • ? Double-barrier methods (which means a barrier method used by both partners at the same time), even when used with spermicide, are not considered to be highly reliable contraception methods, and as such, may not be the only forms of contraception used
  • One of the other listed highly reliable methods must be used in
  • conjunction with a barrier method.
  • b. Female subjects must agree not to breastfeed starting from the time of Screening, throughout the study, and until after 6 months following the last dose of study drug.
  • c. Male subjects must agree not to donate sperm starting from the time of randomization, throughout the study, and until after 6 months following the last dose of study drug
  • d. For subjects and partners considered not of childbearing potential, the following conditions apply:
  • a. Menopausal females must have experienced their last period more than 12 months prior to the date of informed consent to be classified as not of childbearing potential.
  • b. Male and female subjects are in a situation of abstinence from
  • heterosexual intercourse from Screening until after 6 months following the las
