Can a daily pill boost blood counts in fanconi anemia?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

INCLUSION CRITERIA: * Confirmed diagnosis of Fanconi anemia. Diagnosis is confirmed by a biallelic mutation in a known FANC gene and/or by positive chromosome breakage analysis in lymphocytes and/or skin fibroblasts (for mosaicism). * One or more of the following three clinically-significant cytopenias: * Platelet count \<= 50,000/microliter or platelet-transfusion-dependence (requiring at least 4 platelet transfusions in the 8 weeks prior to study entry) * Neutrophil count less than 1000/microliter * Hemoglobin less than 10 g/dL or red cell transfusion- dependence (requiring at least 4 transfusions of PRBCs (adult patient 4 units PRBC, pediatric patients at least 10ml/kg/transfusion) in the eight weeks prior to study entry. * Failed or declined treatment with androgens (danazol or oxymetholone). * Age \>= 6 years old. * Weight \>=10kg. Transfusion Units: Single donor apheresis platelets have become the primary source of platelets in the US. Therefore, one transfused, single donor platelet apheresis product is considered 1 unit for protocol purposes. In the rare case that a patient received pooled platelet products, each completed platelet transfusion (1 bag) independent of donor units pooled, will be counted as 1 unit transfused. In analogy, each completed platelet transfusion will be counted as one unit in pediatric patients independent of the administered volume. EXCLUSION CRITERIA: * Known active or uncontrolled infections not adequately responding to appropriate therapy. * Evidence for MDS or AML as defined by WHO criteria. * Any cytogenetic abnormality associated with poor prognosis in FA, including gains of chromosome 3q, gains of chromosome 1q, deletions of chromosome 7, and complex cytogenetics identified from bone marrow aspirate. Patients with known biallelic mutations in BRCA2 (FANCD1). * Active malignancy or likelihood of recurrence of malignancies within 12 months * Moribund status such that death within 7 to 10 days is likely. Comorbidities of such severity that in the view of the investigator it would likely preclude the patient's ability to tolerate eltrombopag. * Treatment with androgens (danazol or oxymetholone) less than 4 weeks prior to initiating eltrombopag. * Creatinine \> 2.5 times ULN * Direct Bilirubin \> 3.0mg/dL, indicating congenital abnormalities in the bilirubin level * SGOT (AST) or SGPT (ALT) \>5 times the ULN normal * Known liver cirrhosis in severity that would preclude tolerability of eltrombopag as evidenced by albumin \< 35g/L * Known immediate or delayed hypersensitivity to EPAG or its components * Female subjects who are nursing or pregnant (positive serum or urine Beta-human chorionic gonadotrophin (Beta-hCG pregnancy test) at screening or pre-dose on Day 1. * Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 30 days after the last dose of EPAG. Highly effective contraception methods include: * Total abstinence (when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception * Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment * Male sterilization (at least 6 months prior to screening). For female patients on the study the vasectomized male partner should be the sole partner for that patient. * Use of oral, injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate \<1%), for example hormone vaginal ring or transdermal hormone contraception. * 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. * Women are considered post-menopausal and not of child bearing potential if they have had over 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile age appropriate (e.g. generally 40-59 years), history of vasomotor symptoms (e.g. hot flushes) in the absence of other medical justification or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of childbearing potential. * Sexually active males unless they use a condom during intercourse while taking the study treatment and for 30 days after stopping study treatment and should not father a child in this period. A condom is required to be used also by vasectomized men as well as during intercourse with a male partner in order to prevent delivery of the drug via seminal fluid. * History of thromboembolic events. * Unable to take oral medication * History or current diagnosis of cardiac disease indicating significant risk of safety for patients participating in the study such as uncontrolled or significant cardiac disease, including any of the following: * Recent myocardial infarction (within last 6 months), * Uncontrolled congestive heart failure, * Unstable angina (within last 6 months) * Clinically significant (symptomatic) cardiac arrhythmias (e.g., sustained ventricular tachycardia, and clinically significant second or third-degree AV block without a pacemaker.) * Long QT syndrome, family history of idiopathic sudden death, congenital long QT syndrome or additional risk factors for cardiac repolarization abnormality, as determined by the investigator. * Impaired cardiac function such as corrected QTc\>450msec using Fridericia correction on the screening EKG, other clinically significant cardio-vascular diseases (e.g. uncontrolled hypertension, history of labile hypertension), history of known structural abnormalities (e.g. cardiomyopathy). * History of HIV positivity. * History of alcohol/drug abuse. * Concurrent participation in an investigational study within 30 days prior to enrollment or within 5-half-lives of the investigational product, whichever is longer. Note: parallel enrollment in a disease registry is permitted.
