Cancer therapy-induced thrombocytopenia (CTIT) is a common complication in patients with solid tumors during their cancer treatment. The sole therapeutic agents approved for this indication are recombinant human interleukin-11 (rhIL-11) or recombinant human thrombopoietin (rhTPO). Romiplostim-N01 is a novel thrombopoietic agent launched in China in 2024, which has demonstrated preliminary therapeutic efficacy in the management of CTIT. This retrospective study compared romiplostim-N01 with rhIL-11 or rhTPO for CTIT management. Ninety-two matched consecutive patients with grade ≥2 CTIT (platelet PLT count .05). The median duration of chemotherapy delay was significantly shorter in the romiplostim-N01 group compared with the rhIL-11/rhTPO group (5.5 vs 9.5 days, P < .001). Multivariate regression analysis confirmed that romiplostim-N01 was independently associated with an elevation in PLT count. These findings position romiplostim-N01 as a favorable alternative to rhIL-11 or rhTPO in CTIT, given its enhanced early PLT response and reduced risk of chemotherapy disruption.
