Filter by:Eltrombopag olamine (SB-497115-GR) is an orally bioavailable, small molecule thrombopoietin receptor agonist that may be beneficial in medical disorders associated with thrombocytopenia. Eltrombopag has been shown to increase platelet counts in patients with thrombocytopenia from various etiologies (Idiopathic thrombocytopenic purpura [ITP], liver disease, aplastic anemia and chemotherapy induced thrombocytopenia). Approximately 350 subjects will be randomized in a 1:1 ratio (175 into the eltrombopag arm and 175 into the placebo arm). Approximately 55 subjects will be enrolled into the azacitidine. Subjects with intermediate-1, intermediate-2 or high risk MDS by IPSS, and baseline platelet count of <75 Giga (10^9) per liter (Gi/L) will only be enrolled. This is a randomized, double-blind, parallel group, placebo-controlled study designed to explore the platelet supportive care effects of eltrombopag versus placebo in combination with the standard of care hypomethylating agent, azacitidine. The primary objective of this study is to determine the effect of eltrombopag versus placebo on the proportion of subjects who are platelet transfusion free during the first 4 cycles of azacitidine therapy. Key secondary endpoints include overall survival, disease response, and disease progression.
The objective of this study was to provide continued treatment with eltrombopag for subjects who were participating in a Novartis-sponsored investigational study with eltrombopag (parent studies 114968/ASPIRE (NCT01440374), PMA112509 (NCT00903422), and TRA105325/EXTEND (NCT00351468), receiving clinical benefit without unacceptable toxicity and to collect long-term safety data.
The purpose of the current Phase I, open-label, three-period, single sequence, crossover study, TPL116010, is to evaluate the potential drug-drug interaction between eltrombopag (ELT) and bocrprevir (BCP) and between ELT and telaprevir (TLP) in healthy subjects. In this study there will be a screening visit, three treatment periods, and a follow-up visit. In Period 1, subjects will receive a single dose of ELT on Day 1, and pharmacokinetic (PK) sampling will occur for 72 hours. In Period 2, subjects will receive BCP/TLP for 10 days with PK sampling for 8 hours. In Period 3, subjects will receive a single dose of ELT with BCP/TLP on Day 1 only with PK sampling for 72 hours. Subjects will return for a follow-up visit within 10 to 14 days of the last dose of study drugs. The total duration of the study from Screening to Follow-up will be approximately 9 weeks.
This is a worldwide, three-part (Part 1: open-label, Part 2: randomized, double-blind, Part 3: extension), multi-center study to evaluate the effect of eltrombopag in subjects with myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML) who have thrombocytopenia due to bone marrow insufficiency from their underlying disease or prior chemotherapy. This objective will be assessed by a composite primary endpoint that consists of the following: the proportion of ≥Grade 3 hemorrhagic adverse events, or platelet counts <10 Gi/L, or platelet transfusions. Patients with MDS or AML and Grade 4 thrombocytopenia due to bone marrow insufficiency from their underlying disease or prior chemotherapy will be enrolled in the study. No low or intermediate-1 risk MDS subjects will be enrolled in the study. Subjects must have had at least one of the following during the 4 weeks prior to enrolment: platelet count <10 Gi/L, platelet transfusion, or symptomatic hemorrhagic event. Supportive standard of care (SOC), including hydroxyurea, will be allowed as indicated by local practice throughout the study. The study will have 3 sequential parts. Subjects who are enrolled in Part 1 (open-label) cannot be enrolled in Part 2 of the study (randomized, double-blind); however, subjects who complete the treatment period for Part 1 or Part 2 (8 and 12 weeks, respectively) will continue in Part 3 (extension) if the investigator determines that the subject is receiving clinical benefit on treatment.
An indirect comparison to compare the efficacy of eltrombopag versus romiplostim
The purpose of the meta-analysis was to explore the efficacy of eltrombopag versus placebo (standard of care)
The present study is a randomized, blinded, placebo-controlled, two-Phase, sequential cohort, dose finding study to assess the safety and efficacy of eltrombopag in patients with solid tumors receiving gemcitabine monotherapy or the combination of gemcitabine plus carboplatin or cisplatin. Phase I of the study will examine safety and tolerability of various doses of eltrombopag to identify a dose and schedule of eltrombopag. Phase II will confirm that the chosen dose and schedule of eltrombopag from Phase I can deliver clinically meaningful benefit(s) to thrombocytopenic patients by improving platelet numbers.
This is a Phase IV study to evaluate eltrombopag concentrations in breast milk of nursing mothers taking marketed eltrombopag (PROMACTA®). Up to 10 subjects (mother-infant pairs) at as many as 10 study centers in the US will be enrolled. Nursing mothers who are registered with the PROMACTA Pregnancy Registry will be offered the option to participate in this trial if they continue to take commercial eltrombopag post-delivery and decide to breastfeed their infant. Information will be collected in a diary. Breast milk samples will be collected before and after infant feedings for a 24 hour period after eltrombopag dosing to evaluate the eltrombopag concentrations in the breast milk. Mothers will also be given the option to have a pharmacokinetic (PK) blood sample collected from the infant.
The study will evaluate the safety and tolerability, optimal biologic dose, and pharmacokinetics of eltrombopag for patients with advanced sarcoma who have a low platelet count and are receiving ADRIAMYCIN and ifosfamide (AI) chemotherapy.
SB497115 is an oral agent which activates the thrombopoietin receptor and increases platelet counts in healthy volunteers. This study is examining several different doses of SB497115 versus placebo as treatment for patients with advanced solid tumors scheduled to receive chemotherapy with carboplatin and paclitaxel every 21 days. Patients will receive SB497115 on days 2-11 of each 21 day cycle for at least 2 cycles of chemotherapy and for a maximum of 8 cycles of chemotherapy.
