简要总结
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.

- •8. No participation in other clinical trials of drugs within 4 weeks prior to enrollment;
- •9. Subjects must understand the study details and voluntarily sign the Informed Consent Form (ICF);
- •10. No severe complications such as active massive gastrointestinal bleeding, perforation, jaundice, gastrointestinal obstruction, or non-cancerous fever > 38℃;
- •11. Expected to have good compliance and be able to complete follow-up for efficacy and adverse reactions as required by the protocol.
排除标准
- •1. Thrombocytopenia not caused by cancer therapy occurring within 6 months prior to screening, including but not limited to hepatic cirrhosis with hypersplenism, infection, and bleeding;
- •2. Having other hematopoietic system diseases besides chemotherapy-induced thrombocytopenia, including leukemia, primary immune thrombocytopenia (ITP), myeloproliferative diseases (MPDs), multiple myeloma (MM), myelodysplastic syndromes (MDS), etc.;
- •3. Complicated with bone marrow involvement or bone marrow metastasis;
- •4. Having received pelvic, spinal radiotherapy or large-field bone irradiation within 3 months prior to screening;
- •5. History of any arterial or venous thrombosis occurring within 6 months prior to screening;
- •6. Clinical manifestations of severe bleeding (such as gastrointestinal bleeding) within 2 weeks prior to screening;
- •7. Severe cardiovascular diseases (e.g., NYHA Cardiac Function Classification Grade III-IV) within 6 months prior to screening, or patients with arrhythmias known to increase thromboembolic risk (such as atrial fibrillation [AF]), history of coronary artery stenting, angioplasty, or coronary artery bypass grafting (CABG);
- •8. Brain tumor or brain metastasis;
- •9. Having received platelet transfusion within 2 days prior to enrollment;
- •10. Having received treatment with recombinant human thrombopoietin (rhTPO), recombinant human interleukin-11 (rhIL-11), or thrombopoietin receptor agonist drugs (such as eltrombopag, avatrombopag) within 5 days prior to screening;
- •11. Patients with known or anticipated allergy or intolerance to the active ingredient or excipients of Hetrombopag Ethanolamine Tablets (excipients include: cellulose-lactose, low-substituted hydroxypropyl cellulose [L-HPC], magnesium stearate, film-coating premix);
- •12. Pregnant or lactating women;
- •13. Patients deemed ineligible for enrollment by the investigator.
