CTIT-Chemotherapy Induced Thrombocytopenia

This study is a single-arm, exploratory, self-controlled clinical trial for the prevention of thrombocytopenia induced by gemcitabine plus cisplatin in the treatment of nasopharyngeal carcinoma. It aims to investigate the efficacy and safety of hetrombopag for the secondary prevention of thrombocytopenia caused by gemcitabine plus cisplatin in patients with nasopharyngeal carcinoma. The study protocol has been reviewed and approved by the Institutional Ethics Committee of Fujian Cancer Hospital, allowing the conduct of this clinical study.

The title of this study is: A two-cohort, single-arm, exploratory Phase II clinical study on the primary/secondary prevention ADC drug of heltrombopag for thrombocytopenia caused by breast cancer. This study is a two-cohort, single-arm, open-label, exploratory clinical trial for the prevention of thrombocytopenia caused by ADC drug treatment for breast cancer. This research was supported by Fujian Cancer Hospital. The protocol has been reviewed by the Ethics Committee of Fujian Cancer Hospital, which has agreed to conduct this clinical study.

The purpose of this clinical trial is to evaluate the safety and efficacy of Romiplostim N01 in patients with solid tumors who are undergoing concurrent/sequential radiotherapy and chemotherapy（combined with/without immunotherapy）-related thrombocytopenia. All eligible patients will be stratified and randomly assigned based on baseline platelet count（Stratification factors: whether the baseline platelet count of the patients is greater than 50×10\^9/L. ） . All patients will be randomly assigned in a 1:1 ratio to experimental group or control group: Experimental group: Romiplostim N01 (N=53) Control group：Human Interleukin-11(rhlL-11) (N=53) The main questions this trial aims to answer are: 1. The proportion of patients who received platelet transfusion due to thrombocytopenia during the treatment process, as well as the adjustment, delay and discontinuation of radiotherapy and chemotherapy doses； 2. Can patients treated with Romiplostim N01 restore their platelet count to ≥ 100×10\^9/L and what is the response rate of patients during the treatment (response criteria: no need for platelet transfusion and PLT increase ≥ 50×10\^9/L or at least twice the baseline or PLT increase to ≥ 100×10\^9/L)；3. The safety and tolerance of Romiplostim N01 in treating CTIT.
