Besides changing anticancer regimens, standard management of CIT has been limited to platelet transfusions and supportive care. Use of the thrombopoietin receptor agonist romiplostim, already approved for use in immune thrombocytopenia, has shown promising signs of efficacy in CIT. In a phase 2 prospective randomized study of solid tumor patients with platelet counts &lt;100\u2009\u00d7\u200910\n                    <jats:sup>9<\/jats:sup>\n                    \/L for \u22654\u2009weeks due to CIT, weekly romiplostim corrected the platelet count to &gt;100\u2009\u00d7\u200910\n                    <jats:sup>9<\/jats:sup>\n                    \/L in 93% (14\/15) of patients within 3\u2009weeks versus 12.5% (1\/8) of untreated patients (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001). Including patients treated with romiplostim in an additional single\u2010arm cohort, 85% (44\/52) of all romiplostim\u2010treated patients responded with platelet count correction within 3\u2009weeks. Several retrospective studies of CIT have also shown responses to weekly romiplostim, with the largest study finding that poor response to romiplostim was predicted by tumor invasion of the bone marrow (odds ratio, 0.029; 95% CI: 0.0046\u20130.18;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001), prior pelvic irradiation (odds ratio, 0.078; 95% CI: 0.0062\u20130.98;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.048), and prior temozolomide treatment (odds ratio 0.24; 95% CI: 0.061\u20130.96;\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.043). Elsewhere, lower baseline TPO levels were predictive of romiplostim response (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.036). No new safety signals have emerged from romiplostim CIT studies. Recent treatment guidelines, including those from the National Comprehensive Cancer Network, now support consideration of romiplostim use in CIT. Data are expected from two ongoing phase 3 romiplostim CIT trials.\n                  <\/jats:p>","DOI":"10.1002\/cam4.7429","type":"journal-article","created":{"date-parts":[[2024,8,13]],"date-time":"2024-08-13T00:44:41Z","timestamp":1723509881000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Romiplostim in chemotherapy\u2010induced thrombocytopenia: A review of the literature"],"prefix":"10.1002","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8781-903X","authenticated-orcid":false,"given":"Gerald A.","family":"Soff","sequence":"first","affiliation":[{"name":"University of Miami Health System\/Sylvester Comprehensive Cancer Center  Miami Florida USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanny","family":"Al\u2010Samkari","sequence":"additional","affiliation":[{"name":"Center for Hematology, Massachusetts General Hospital Cancer Center Harvard Medical School  Boston Massachusetts USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Avi","family":"Leader","sequence":"additional","affiliation":[{"name":"Section of Hematology, Memorial Sloan Kettering Cancer Center  New York New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melissa","family":"Eisen","sequence":"additional","affiliation":[{"name":"Amgen Inc.
