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 study is designed to investigate the safety profile and the photoirritant potential of eltrombopag in healthy subjects. The study is placebo- and positive controlled, randomized, parallel group with three treatment arms: eltrombopag (75 mg QD), placebo, and a positive control (ciprofloxacin, 500 mg BID). Eltrombopag will be administered in a double-blind fashion with respect to placebo and the positive control, ciprofloxacin, will be administered under observer-blinded conditions. Twelve to fifteen subjects will be recruited into each arm, to assure total enrollment of 36 evaluable subjects. The primary endpoint is the photosensitizing potential of eltrombopag as measured by photoirritant index (PI) and change in minimum erythemal dose (MED) in comparison with placebo.

OBJECTIVE:

To investigate the safety and efficacy of eltrombopag for adult patients with chronic immune thrombocytopenia (cITP).

METHODS:

It was a randomised, single-centre, 6 weeks, placebo-controlled study. Beginning in January 29(th), 2013, 35 patients were enrolled, and the trial was completed on May 16(th), 2014. 17 patients were assigned to receive eltrombopag (starting dose 25 mg/d) and 18 were assigned to receive placebo.

RESULTS:

A total of 35 cases of adult cITP, 6 males and 29 females with a median age of 42(22-66) years were enrolled. One patient withdrew from eltrombopag treatment group for the adverse event (AE) and discontinued treatment. In first two weeks, 27.78% (5/18) of placebo-treated compared with 64.71%(11/17) of eltrombopag-treated patients achieved platelet counts ≥ 30×10(9)/L(P=0.031); Treatment 6 weeks, the proportion of platelet counts reached ≥50×10(9)/L and ≥ 30×10(9)/L in eltrombopag-treated were higher than placebo-treated ones with statistically significant differences in both groups [64.71%(11/17) vs 11.11% (2/18), P=0.001; 76.47% (13/17) vs 38.89% (7/18), P=0.028]; The study also indicated a statistically significant difference in favour of eltrombopag compared with placebo in the odds of achieving the outcome of a platelet count ≥ 50×10(9)/L at least once during 6-week treatment (94.11% vs 33.33%, P<0.001), and 70.59%(12/17) of patients with the platelet count continuously ≥ 50×10(9)/L in 50% of treatment time in eltrombopag-treated group was more than placebo-treated one [11.11%(2/18), P<0.001]. Proportions of patients who required rescue treatment were 44.44% in placebo group and none in eltrombopag-treated one, respectively (P=0.002); The odds of bleeding symptoms with the WHO bleeding scale had no difference in both groups after 6 weeks (P=0.066). Adverse events that occurred more frequently due to eltrombopag than placebo included increased transaminase (3/17) and blood bilirubin (5/17), cerebral infarction(1/17).

CONCLUSIONS:

The thrombopoietin receptor agonist eltrombopag was a suitable therapeutic option for Chinese adults with cITP.

PURPOSE:

Eltrombopag was evaluated as a second-line treatment for adult chronic immune thrombocytopenia (ITP) in the 2006 Phase III RAISE (Eltrombopag for Management of Chronic Immune Thrombocytopenia) randomized, placebo-controlled trial. More than 80% of patients reached satisfactory platelet counts within 2 weeks. However, the economic value of eltrombopag as a second-line treatment for ITP remains to be formally assessed. This study aimed to estimate the cost-effectiveness of treating ITP with a comparable thrombopoietin receptor agonist (eltrombopag vs romiplostim).

METHODS:

A Markov model was implemented over a lifetime time horizon to estimate the benefits and costs of each treatment. The model featured 3 health states based on current guidelines: (1) on treatment; (2) treatment failure/discontinuation; and (3) mortality. In line with therapeutic goals in ITP, model patients could experience 3 events: no bleeding, mild/moderate bleeding, or severe bleeding. Data on eltrombopag use were obtained from an open-label extension of previous Phase II/III trials, including RAISE. Romiplostim data were obtained from Phase III trials and an extension study. Lifetime overall survival was extrapolated by using treatment-specific mortality rates derived from severe bleeding and natural mortality rates. The costs of drugs, routine care, bleeding episodes, adverse events, and mortality were represented in the model.

FINDINGS:

Eltrombopag-treated patients gained 17.58 life years and 14.68 quality-adjusted life years, whereas romiplostim-treated patients gained 17.52 life years and 14.67 quality-adjusted life years. The total lifetime cost of eltrombopag treatment was estimated at $1.58 million versus $2.13 million for romiplostim. Sensitivity analyses supported base case findings. Deterministic sensitivity analysis predicted the greatest sensitivity to the rates of severe bleeding, discontinuation, and natural mortality. Probabilistic sensitivity analysis showed that eltrombopag would be an efficient use of resources at a $50,000 threshold in 52.8% of cases. In all probabilistic iterations, the total cost of eltrombopag treatment was lower than with romiplostim, primarily because of lower drug costs.

IMPLICATIONS:

Clinical data were applied in an economic analysis, and eltrombopag exhibited economic dominance compared with romiplostim, driven largely by the reduced costs of primary therapy. This model was limited by a lack of specific patient-level data and robust data on the duration of secondary therapy, as well as by the fact that utilization values are likely conservative estimates for routine care use.

This phase II trial studies how well lenalidomide (LEN) and eltrombopag olamine (ELT) work in treating patients with symptomatic anemia in low or intermediate myelodysplastic syndrome (MDS). Lenalidomide may stimulate the immune system in different ways and stop cancer cells from growing. Eltrombopag olamine may increase the number of white blood cells and platelets found in bone marrow or peripheral blood. Giving lenalidomide and eltrombopag olamine may be an effective treatment for myelodysplastic syndrome.

Inherited thrombocytopenias represents a heterogenous group of diseases characterized by a congenital reduction in the platelet count that could lead to a bleeding tendency. MYH9-related disorders are characterized by large platelets and congenital thrombocytopenia. Thrombopoietin-receptor agonists: eltrombopag and romiplostim are currently approved in many countries for the treatment of different forms of acquired thrombocytopenia, such as immune thrombocytopenia. We report, instead, the successful use of eltrombopag to treat inherited thrombocytopenia in a patient with an MHY9-related disease. This is the first report of a chronic use of eltrombopag to elevate platelets in MYH9-related disorders without side effects.

This phase II trial studies how well eltrombopag olamine works in increasing platelet counts in patients undergoing transplant. Eltrombopag olamine may help platelet counts and the immune system recover from blood or bone marrow transplant.

Thrombopoietin Receptor Agonists (TPO-ra) are novel treatments for patients with refractory Primary Immune Thrombocytopenia (ITP). Rh-TPO and eltrombopag increase the number of platelets through different mechanism. If there is cross-resistance between 2 drugs for the treatment of adult ITP is still no answer. The purpose of this study is to investigate the efficacy and safety of switching eltrombopag and Rh-TPO in adults with ITP.

Patients with inherited thrombocytopenias often require platelet transfusions to raise their platelet count before surgery or other invasive procedures; moreover, subjects with clinically significant spontaneous bleeding may benefit from an enduring improvement of thrombocytopenia. The hypothesis that thrombopoietin-mimetics can increase platelet count in inherited thrombocytopenias is appealing, but evidence is scarce. We conducted a prospective, phase II clinical trial to investigate the efficacy of the oral thrombopoietin-mimetic eltrombopag in different forms of inherited thrombocytopenia. We enrolled 24 patients affected by MYH9-related disease, ANKRD26-related thrombocytopenia, X-linked thrombocytopenia/ Wiskott-Aldrich syndrome, monoallelic Bernard-Soulier syndrome, or ITGB3-related thrombocytopenia. The average pre-treatment platelet count was 40.4 ×109/L. Patients received a 3- to 6-week course of eltrombopag in a dose-escalated manner. Of 23 patients evaluable for response, 11 (47.8%) achieved a major response (platelet count >100 ×109/L), ten (43.5%) had a minor response (platelet count at least twice the baseline value), and two patients (8.7%) did not respond. The average increase of platelet count compared to baseline was 64.5 ×109/L (P<0.001). Four patients with clinically significant spontaneous bleeding entered a program of long-term eltrombopag administration (16 additional weeks): all of them obtained remission of mucosal hemorrhages, with the remission persisting throughout the treatment period. Treatment was globally well tolerated: five patients reported mild adverse events and one patient a moderate adverse event. In conclusion, eltrombopag was safe and effective in increasing platelet count and reducing bleeding symptoms in different forms of inherited thrombocytopenia. Despite these encouraging results, caution is recommended when using thrombopoietinmimetics in inherited thrombocytopenias predisposing to leukemia. ClinicalTrials.gov identifier: NCT02422394.

This will be a double-blind, placebo-control, randomized clinical trial conducted in the Department of Hematology, DMCH for one year. This study will help to establish the role of eltrombopag as a first-line therapy in newly diagnosed ITP. Newly diagnosed ITP patients will be selected after meeting inclusion and exclusion criteria, they will be thoroughly informed about the study, used drugs, randomization, risks, benefits, and follow-up. If they agree to participate, their consent will be taken and they will be enrolled in the study. A detailed history and clinical exam will be done. Primary investigation will be - CBC PBF, RBS, ANA, TSH, Anti H. pyloriIgG, Anti-HCV, APTT, and BMS (if indicated). The main outcome variable will be platelet count and number of spontaneous bleeding. Total sample size would be 100 (50 in each group). Enrolled patients would be divided into two groups (1:1) by block randomization. One group will get Eltrombopag\& Prednisolone and other group will get Eltrombopag\& Placebo. Researchers or any one related to the study in DMCH, patients \& their attendants, no one will know which patient will get placebo or eltrombopag. Only a respectable third party will know the information. A patient would be followed up on 1st, 2nd and 4th week of starting therapy. Patients would be evaluated in every follow up by history, physical examination and investigation. History of any spontaneous bleeding event, any discomfort or new symptoms science last follow up will be noted. General examination will be performed in every follow-up. CBC, RBS, ALT, AST, creatinine will be done in every follow-up. Data will be collected on a pre-designed case record form and will be collected through face-to-face interviews, physical examination, and laboratory reports. After data collection data will be edited, cleaned, and prepared for analysis at the end of the study. The statistical analysis will be conducted using SPSS version 25 statistical software. The results of the study will be published in national and international journals.
