Since then, new therapeutic indications have been approved for some of these therapies,<a class="elsevierStyleCrossRef" href="#bib0200">5</a> and large randomized controlled trials (RCTs) have been recently published.<a class="elsevierStyleCrossRefs" href="#bib0225">10–12</a> Therefore, we considered timely to update our original systematic review and meta-analysis examining whether TPOr agonists affect thromboembolism occurrence in adult thrombocytopenic patients.MethodsFor this updated systematic review, we largely followed the methods as our 2012 review.<a class="elsevierStyleCrossRef" href="#bib0220">9</a>Search strategy and selection criteriaWe searched PubMed/MEDLINE, and the Cochrane Central Register of Controlled Trials with the specific terms: “romiplostim” and “eltrombopag”, for articles published from January 2011 to December 2014 and without language restriction. The Cochrane highly sensitive search strategy for identifying RCTs<a class="elsevierStyleCrossRef" href="#bib0240">13</a> was used (see <a class="elsevierStyleCrossRef" href="#sec0065">Appendix A</a>Appendix for specific search strategy). We also searched websites of the European Medicines Agency (<a id="intr0050" class="elsevierStyleInterRef" href="http://www.ema.europa.eu/">www.ema.europa.eu</a>) and of the U.S. Food and Drug Administration (<a id="intr0055" class="elsevierStyleInterRef" href="http://www.fda.gov/">www.fda.gov</a>). On-line clinical trials registries, including government (<a id="intr0060" class="elsevierStyleInterRef" href="http://www.clinicaltrials.gov/">www.clinicaltrials.gov</a>) and manufacturers (<a id="intr0065" class="elsevierStyleInterRef" href="http://www.amgentrials.com/">www.amgentrials.com</a> and, <a id="intr0070" class="elsevierStyleInterRef" href="http://www.gsk-clinicalstudyregister.com/">www.gsk-clinicalstudyregister.com</a>) were also searched, to identify eligible unpublished reports.The selection criteria followed those of the original review.<a class="elsevierStyleCrossRef" href="#bib0220">9</a> Briefly, selected studies had to be RCTs in adult thrombocytopenic patients exposed to romiplostim or eltrombopag in at least one treatment arm, and containing the outcome of interest (thrombotic and thromboembolic events). Only direct comparisons with control interventions (e.g., placebo and/or standard of care) were considered.Data collection and quality analysisData extraction from source documents was done independently by two reviewers. Disagreements were resolved by consensus. Should more than one report of the same clinical trial exist, the report with the most updated or complete data was included. The quality of studies included was independently assessed by two reviewers without blinding to authorship or journal using the Jadad's scale.<a class="elsevierStyleCrossRef" href="#bib0245">14</a> As in the original report,<a class="elsevierStyleCrossRef" href="#bib0220">9</a> the number of patients with a thromboembolic event and total number of patients in each trial group were extracted and tabulated, along with other information including disease conditions studied, trial design and duration, age, sex, race, and platelet counts at baseline, among others (<a class="elsevierStyleCrossRefs" href="#tbl1">Tables 1 and 2</a>).<elsevierMultimedia ident="tbl1"></elsevierMultimedia><elsevierMultimedia ident="tbl2"></elsevierMultimedia>Statistical analysesWe reported this systematic review and meta-analysis in line with recommendations from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.<a class="elsevierStyleCrossRefs" href="#bib0250">15,16</a> In the primary analyses, relative risks (RR) were provided to compare the likelihood of thromboembolisms between two groups. Absolute risk ratios (ARR) and number needed to harm (NNH) were also calculated to provide the population health impact of the treatment exposures with TPOr agonists. Data were pooled by using both random-effects and fixed-effects models.<a class="elsevierStyleCrossRefs" href="#bib0260">17,18</a> Heterogeneity was assessed using Cochran's Q test and I2 statistic.<a class="elsevierStyleCrossRef" href="#bib0270">19</a> Begg's rank-correlation method was used to assess publication bias and a funnel plot was also generated.<a class="elsevierStyleCrossRefs" href="#bib0275">20,21</a> In addition, sensitivity analyses were conducted to measure the robustness of the main results by using a Jackknife approach (assessment on heterogeneity and/or effect size when removing one trial or a group of trials). A sensitivity analysis was also conducted to examine the possible influence of single studies by excluding possible outlier (extreme) observations. The identification of a study as an outlier was not based on an a priori statistical criterion, but rather on visual evaluation of forest plot with all selected studies.All the statistical analyses were conduced using Stata 12 (StataCorp, LP, College Station, TX, USA).ResultsStudy identification and selectionOur previous review<a class="elsevierStyleCrossRef" href="#bib0220">9</a> included 8 studies in 1180 patients. Since then, 7 new studies have been identified. A total of 15 studies<a class="elsevierStyleCrossRefs" href="#bib0225">10–12,22–33</a> were included in this updated systematic review (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>).<elsevierMultimedia ident="fig0005"></elsevierMultimedia>Study and patient characteristicsCharacteristics of the trials and patients are summarized in <a class="elsevierStyleCrossRefs" href="#tbl1">Tables 1 and 2</a>. Overall, the 15 studies<a class="elsevierStyleCrossRefs" href="#bib0225">10–12,22–33</a> enrolled a total of 3026 patients, with 2003 patients randomized to TPOr agonists, and 1023 assigned to controls (in a 2:1 ratio). Eight studies included eltrombopag as study drug.<a class="elsevierStyleCrossRefs" href="#bib0225">10,11,26–29,33</a> Six trials included patients with ITP,<a class="elsevierStyleCrossRefs" href="#bib0285">22–25,27–29</a> 3 trials were conducted in advanced cancer patients with chemotherapy-induced thrombocytopenia,<a class="elsevierStyleCrossRefs" href="#bib0305">26,32,33</a> 3 trials included thrombocytopenic patients with chronic liver disease<a class="elsevierStyleCrossRefs" href="#bib0225">10,11</a> and 3 trials in thrombocytopenic patients with myelodysplastic syndromes.<a class="elsevierStyleCrossRefs" href="#bib0235">12,30,31</a> The mean age of patients was 56.9 years-old and the percentage of women ranged from 21% to 87%.

We found that the quality of reporting among studies was variable. The average quality of the trials scored 2.5 in the Jadad's scale, and ranged from 0 (in two trials)<a class="elsevierStyleCrossRefs" href="#bib0285">22,25</a> to 4 (in three trials).<a class="elsevierStyleCrossRefs" href="#bib0230">11,28</a> Four studies<a class="elsevierStyleCrossRefs" href="#bib0285">22,25–27</a> with score ≤1 were considered of unacceptable reporting quality. Regarding potential sources of sponsorship bias, the 7 trials on romiplostim<a class="elsevierStyleCrossRefs" href="#bib0235">12,22,25,30–32</a> were funded by Amgen, the manufacturer of romiplostim (Nplate®), and the 8 trials on eltrombopag<a class="elsevierStyleCrossRefs" href="#bib0225">10,11,26–29,33</a> were funded by GlaxoSmithKline, the manufacturer of eltrombopag (Revolade®).Main resultsThe analysis of the outcome of interest was based on 89 patients with thromboembolisms (83.14% of them were TPOr agonists-treated patients). Estimated frequency of thromboembolisms was 3.69% (95% CI: 2.95–4.61%) for TPOr agonists and 1.46% (95% CI: 0.89–2.40%) for controls (e.g., placebo and/or standard of care).In the overall meta-analysis, for patients receiving TPOr agonists versus controls, we showed an absolute risk increase of 2.10% (95% CI: 0.03–3.90%) corresponding to a meta-analytic NNH of 48 and an 81% risk increase of thromboembolims (RR=1.81; 95% CI: 1.04–3.14; p=0.041). Overall, we did not find evidence of statistical heterogeneity (p=0.43; I2=1.60%) (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>).<elsevierMultimedia ident="fig0010"></elsevierMultimedia>Subgroup analysis based on only trials conducted in non-ITP patients (9 trials, 2314 patients)<a class="elsevierStyleCrossRefs" href="#bib0225">10–12,26,30–33</a> yielded an absolute risk increase of 2.80% (95% CI: 0.00–5.50%) corresponding to a NNH of 36 and a RR of 2.31 (95% CI: 1.10–4.86; p=0.028) with no evidence of statistical heterogeneity (p=0.210; I2=16.40%). This was largely driven by risk of harm in the cohort of chronic liver disease: RR=2.74 (95% CI: 0.97–7.75; p=0.058), absolute risk increase of 2.40% (95% CI: 0.04–4.3%) and NNH=42 (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>).The test statistic for Begg's rank-correlation method was non-statistically significant (p=0.255) for thromboembolism occurrence, denoting no evidence of publication bias (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>; <a class="elsevierStyleCrossRef" href="#tbl3">Table 3</a>).<elsevierMultimedia ident="fig0015"></elsevierMultimedia><elsevierMultimedia ident="tbl3"></elsevierMultimedia>Sensitivity analysis are presented in <a class="elsevierStyleCrossRef" href="#tbl4">Table 4</a>. Overall, the results showed were consistent and similar to those of the base case meta-analysis. For example, when studies of poor reporting quality were excluded (four trials with Jadad's score ≤1),<a class="elsevierStyleCrossRefs" href="#bib0285">22,25–27</a> the analysis yielded a RR=2.18 (95% CI: 1.16–4.10) and a NNH=40. However, when the most influential trials were excluded,<a class="elsevierStyleCrossRefs" href="#bib0225">10,11,25</a> the sensitivity analysis yielded non-statistically significant results (RR=1.42; 95% CI: 0.62–3.25).<elsevierMultimedia ident="tbl4"></elsevierMultimedia>DiscussionIn this systematic review and updated meta-analysis of data from 15 RCTs, clinical evidence showed a higher risk of thromboembolic events associated to TPOr agonists compared with controls. Statistically significant results were largely driven by trials conducted in non-ITP populations, particularly in the cohort of chronic liver disease.The TPOr agonists analyzed in this study, romiplostim and eltrombopag, represent a therapeutic option for the treatment of adult chronic ITP splenectomised patients who are refractory to other treatments. Treatment of chronic ITP has been traditionally based on strategies aimed to decrease platelet destruction either by surgical (e.g., splenectomy) or pharmacological (e.g., corticosteroids, immunoglobulins, immunosuppressants) approaches. In 2013, the European Commission granted an additional therapeutic indication for TPOr agonist eltrombopag as a treatment for thrombocytopenia in adult patients with chronic hepatitis C virus infection, where the degree of thrombocytopenia is an important factor preventing the initiation or limiting the ability to maintain optimal interferon-based therapy.<a class="elsevierStyleCrossRef" href="#bib0200">5</a> The authorization granted to eltrombopag was based on results from the Eltrombopag to INitiate and Maintain Interferon Antiviral Treatment to Benefit Subjects with Hepatitis C related Liver DiseasE (ENABLE) program,<a class="elsevierStyleCrossRefs" href="#bib0200">5,11</a> two randomized, double-blind, placebo-controlled trials. Patients in ENABLE-1 utilized peginterferon alfa-2a plus ribavirin as antiviral treatment and patients in ENABLE-2 utilized peginterferon alfa-2b plus ribavirin.<a class="elsevierStyleCrossRef" href="#bib0230">11</a> On the current update of our previous review,<a class="elsevierStyleCrossRef" href="#bib0220">9</a> both ENABLE trials were included. In ENABLE program, thromboembolic events were more common in the eltrombopag group in comparison with placebo (34 thromboembolic events in 31 eltrombopag patients [3%] and 5 thromboembolic events in 5 placebo patients [1%]). Reported thromboembolic complications included both venous and arterial events, but portal vein thrombosis was the most common thromboembolic event in both treatment groups (1.2% in eltrombopag versus 0.4% in placebo).<a class="elsevierStyleCrossRef" href="#bib0230">11</a> These results are overall consistent with the results of prior TPOr agonist trials. Particularly, in the ELEVATE trial,<a class="elsevierStyleCrossRef" href="#bib0225">10</a> a double-blind, placebo-controlled trial, 292 patients with thrombocytopenia due to chronic liver disease were randomized to receive TPOr agonist eltrombopag or placebo before an invasive procedure. In that trial,<a class="elsevierStyleCrossRef" href="#bib0225">10</a> eltrombopag reduced the need for platelet transfusions, but it was associated with an increased risk of thromboembolism, as compared with placebo. This finding led to the early termination of the trial. Six (4%) patients receiving TPOr agonist and 2 (1%) patients in the placebo group experienced thromboembolisms, most of them affecting the portal venous system. In the ELEVATE trial,<a class="elsevierStyleCrossRefs" href="#bib0195">4,10</a> 5 of the 6 treated patients experienced thromboembolisms at platelet counts above 200×109L−1.Potential factors such as the rapid increase in platelet counts due to the administration of a higher dose of TPOr agonist, an enhancement of the prothrombotic state (hypercoagulability) due to an imbalance in coagulation factors, or the presence of endothelial damage seen in liver disease may also have contributed to these findings.<a class="elsevierStyleCrossRefs" href="#bib0200">5,9</a> Particularly in ENABLE program, patients with low albumin levels (≤35gL−1) or Model for End Stage Liver Disease (MELD) score ≥10 had a 2-fold greater risk of thromboembolic events than those with higher albumin levels; and those aged ≥60 years had a 2-fold greater risk of thromboembolism compared to younger patients.<a class="elsevierStyleCrossRefs" href="#bib0200">5,11</a> The dosing adjustment schedule of TPOs is another important factor that might influence the thrombotic risk associated with these drugs. Early results from the ELEVATE trial motivated the European Medicines Agency's Committee for Medicinal Products for Human Use to modify the dosing recommendations for both TPOs from 250 to 150×109L−1 and from 400 to 250×109L−1 as the cut off point for dose reduction and dosing interruption respectively.<a class="elsevierStyleCrossRefs" href="#bib0195">4,5,9</a> These changes were not implemented by the U.S. Food and Drug Administration and the ENABLE program was conducted according to the U.S. dosing adjustment schedule, therefore the relevance of these results for different regions setting might not be homogeneous. In any case, the treatment paradigm of hepatitis C virus is rapidly moving and the role of interferon-based therapy in this setting is likely to be downplayed dramatically in the next future, thus relativizing the role of TPOr agonists in this therapeutic indication.Studies in a wide variety of other clinical conditions where thrombocytopenia represents a significant clinical challenge (e.g., advanced myelodysplastic syndromes, or solid tumors receiving chemotherapy) are underway,<a class="elsevierStyleCrossRef" href="#bib0345">34</a> but the effectiveness and safety of TPOr agonists have not been established for use in other thrombocytopenic conditions than chronic ITP (for romiplostim and eltrombopag) and/or thrombocytopenic chronic liver disease (in the case of eltrombopag). Thus, TPOr agonists should not be used outside of clinical trials for the treatment of thrombocytopenia due to myelodysplastic syndromes or any other cause of thrombocytopenia other than the approved indications.<a class="elsevierStyleCrossRefs" href="#bib0200">5,6</a>To the best of our knowledge, no comprehensive update of the original 2012 systematic review and meta-analysis<a class="elsevierStyleCrossRef" href="#bib0220">9</a> has been carried out specifically for examining TPOr agonist class effect on thromboembolism. The present review supersedes all previously published findings on this topic. Our previous 2012 systematic review included 8 RCTs with a total of 1180 adult patients with thrombocytopenia, most of them in ITP patients.<a class="elsevierStyleCrossRef" href="#bib0220">9</a> That meta-analysis revealed that TPOr agonist treatment of adult thrombocytopenic patients was associated with a non-statistically significant trend to increase the risk of thromboembolisms compared to controls (RR=1.49; 95% CI: 0.68–3.27), with a more marked effect in non-ITP studies. However, the low number of total events impeded to show statistical significance. For the current update of our review, we used the same systematic and statistical methods. This updated synthesis of the clinical evidence for the risk of thromboembolism and TPOr agonists identified 7 more RCTs not included in the previous review, all of them contributing new data. The total number of participants increased by 61.0% (from 1180 to 3026 adult patients with thrombocytopenia) and the number of events by 65.2% (from 31 to 89 patients with thromboembolisms).Our study has several limitations. More importantly, we primarily derived our conclusions from trials with highly selected and heterogeneous thrombocytopenic populations of adult patients. Although findings from trials are generally consistent, the evidence is limited to a small number of trials because the majority of trials enrolled small numbers of patients, and most lacked sufficient power to determine potentially subtle differences. For example, we found only statistically significant results in one study (namely, ENABLE-2 trial)<a class="elsevierStyleCrossRef" href="#bib0230">11</a> where treatment effects were considerable and are likely to have clinical relevance. Most trials defined thrombotic risk factors or previous thromboembolic events as exclusion criteria but none used the occurrence of thromboembolisms as the primary outcome. As in other systematic reviews and meta-analyses, we used trial-level data and did not adjust our analyses for dosage of drugs used, compliance to assigned treatment, duration or outcome nature because of the limited reporting data in each trial.Publication bias is a concern for all systematic reviews and has been empirically proven to be problematic for evaluating safety outcomes.<a class="elsevierStyleCrossRef" href="#bib0350">35</a> Although we followed current recommendations for searching complementary sources (including clinical trial registries), potential reporting bias may not have been effectively ruled out. The small number of studies for individual conditions limits the validity of statistical methods to explore publication bias, such as funnel plots. Thus, the potential underreporting of adverse events in published trials is a major concern.In summary, TPOr agonists are associated with potential long-term safety problems, being the statistically significant increased risk of thromboembolic events one of the most obvious. Our results are supportive of the current information provided in the product information in the European Union,<a class="elsevierStyleCrossRefs" href="#bib0195">4,5</a> indicating caution when administering TPOr agonists to patients at risk of thromboembolism.Conflict of interestsThe authors state that they have no conflict of interest.

In 2012, a systematic review and meta-analysis reported a non-statistically significant increased risk of thromboembolic events for these drugs, but analyses were limited by lack of statistical power. Our objective was to update the 2012 meta-analysis examining whether TPOr agonists affect thromboembolism occurrence in adult thrombocytopenic patients. Materials and methodsWe conducted a systematic review and meta-analysis of randomized controlled trials (RCTs). Updated searches were conduced on PubMed, Cochrane Central, and publicly available registries (up to December 2014). RCTs using romiplostim or eltrombopag in at least one group were included. Relative risks (RR), absolute risk ratios (ARR) and number needed to harm (NNH) were estimated. Heterogeneity was analyzed using Cochran's Q test and I2 statistic. ResultsFifteen studies with 3026 adult thrombocytopenic patients were included. Estimated frequency of thromboembolism was 3.69% (95% CI: 2.95–4.61%) for TPOr agonists and 1.46% (95% CI: 0.89–2.40%) for controls. TPOr agonists were associated with a RR of thromboembolism of 1.81 (95% CI: 1.04–3.14) and an ARR of 2.10% (95% CI: 0.03–3.90%) meaning a NNH of 48. Overall, we did not find evidence of statistical heterogeneity (p=0.43; I2=1.60%). ConclusionsOur updated meta-analysis suggested that TPOr agonists are associated with a higher risk of thromboemboembolic events compared with controls, and supports the current recommendations included in the European product information on this respect."

El objetivo es actualizar el metaanálisis de 2012 examinando si los agonistas del TPOr afectan a la incidencia de tromboembolismos en los pacientes adultos con trombocitopenia. Material y métodosSe llevó a cabo una revisión sistemática y metaanálisis de ensayos clínicos aleatorizados y controlados (ECA). Se actualizaron búsquedas llevadas a cabo en PubMed, Cochrane Central, y registros públicos (hasta Diciembre de 2014). Se incluyeron ECA en los que se administrara romiplostim o eltrombopag en al menos uno de los grupos de pacientes tratados. Se calcularon los riesgos relativos (RR), la diferencia absoluta de riesgo (ARR, por sus siglas en inglés) y el número necesario de pacientes para dañar (NNH). Se examinó la heterogeneidad estadística mediante la Q de Cochran y el estadístico I2. ResultadosSe incluyeron 15 estudios con 3026 pacientes adultos diagnosticados de trombocitopenia.
