Trombopenia

Thrombocytopenia associated with ITP.---------------------------trombocitopenia asociada a púrpura trombocitopénica inmune (idiopática) (PTI)


The primary objective of this study is to evaluate the incidence of collagen fibrosis asevidenced by trichrome staining at Year 1, Year 2, or Year 3 after initial exposure of romiplostim.

To evaluate the presence of collagen fibrosis as evidenced by trichrome staining 12 weeks after romiplostim discontinuation in subjects who developed collagen fibrosis at Year 1, Year 2, or Year 3 after exposure of romiplostim.To evaluate the incidence of increased reticulin fibrosis as evidenced by silver staining at Year 1, Year 2, or Year 3 after exposure of romiplostim.To evaluate electrocardiogram (ECG) changes after exposure to romiplostim.To evaluate the incidence of cytopenias (anemia or neutropenia) after exposure to romiplostim.To evaluate the overall safety as evidenced by adverse events and the development of neutralizing antibodies to romiplostim or cross-reacting antibodies to endogenousthrombopoietin.

No


Disease related- Diagnosis of ITP according to American Society of Hematology (ASH) guidelines- Subject must have had a bone marrow biopsy within one year prior to planned firstdose of romiplostim (with available bone marrow tissue block or unstained histological slides to send to a central laboratory for interpretation) or must consentto a pre-treatment bone marrow biopsy within 3 weeks prior to planned first dose ofromiplostim. Central laboratory interpretation is required prior to first dose of romiplostim- Subject must agree to a scheduled bone marrow biopsy at Year 1, Year 2, or Year3 following romiplostim treatment and any unscheduled biopsies if clinically indicatedDemographic- Subject > 18 years of ageLaboratory- Baseline bone marrow reticulin grade of 0, 1, 2, or 3 according to the modifiedBauermeister grading scheme as assessed by central laboratory interpretation- Platelet count < 50x 109/LMedications- Must have received at least 1 prior ITP therapy (examples of ITP therapy includecorticosteroids, IVIG, splenectomy)Ethical- Subject (or legally-acceptable representative) is willing and able to provide writteninformed consent

Disease Related- Baseline bone marrow biopsy positive for collagen fibrosis- Any known history of or currently active bone marrow stem cell disorder, hematological malignancy, myeloproliferative disorder, myelodysplastic syndrome- Any current active malignancy- Any prior exposure to cytostatic chemotherapy or radiotherapy for malignancy- Subject has undergone pacemaker placement, cardiac ablation of arrhythmia, and/or any current treatment with Vaughan Williams Class IA- IC and Class III agents (Vaughan Williams, 1970)Medications- Subject has participated in any study evaluating PEG-rHuMGDF, recombinanthuman thrombopoietin (rHuTPO), or thrombopoietin receptor agonists (ie romiplostimor eltrombopag)- Subject has a known hypersensitivity to any recombinant E coli-derived productGeneral- Subject is currently enrolled in or has not yet completed (at least 4 weeks sinceending) other investigational device or drug trial(s) or subject is receiving otherinvestigational agent(s)- Other investigational procedures are excluded- Subject of child-bearing potential is evidently pregnant (eg positive pregnancy test)or is breast feeding- Subject is not using adequate contraceptive precautions- Subject has any kind of disorder that compromises the ability of the subject to givewritten informed consent and does not have a legally acceptable representativeand/or is unable to comply with study procedures

The primary endpoint is the incidence of collagen fibrosis as evidenced by trichrome staining at Years 1, 2, or 3 after initial romiplostim exposure using the modified Bauermeister grading scale.
