The objective of this study is to describe treatment patterns and outcomes in patients with primary ITP who switched from eltrombopag (ELT) or romiplostim (ROMI) to avatrombopag (AVA). We conducted a retrospective chart review study of adults with primary ITP who initiated ELT or ROMI on or after 1 July 2019, switched to AVA within 30\u2009days of ELT\/ROMI discontinuation and had \u22656\u2009months follow\u2010up after AVA initiation. Patients were followed from AVA initiation until last contact, death or study end (21 March 2025), whichever occurred earliest. Response was defined as achieving \u22651 platelet count (PC) of \u226530\u2009\u00d7\u200910\n                    <jats:sup>9<\/jats:sup>\n                    \/L, \u226550\u2009\u00d7\u200910\n                    <jats:sup>9<\/jats:sup>\n                    \/L or \u2265100\u2009\u00d7\u200910\n                    <jats:sup>9<\/jats:sup>\n                    \/L in the absence of rescue therapy.
