Description for medicine or protocol of treatment in detail:

 

纳入标准:

1. 年龄在 6 月-18 岁之间; 2. 进入“达拉非尼(Dabrafenib)或曲美替尼(Trametinib)联合氯法拉滨(Clofarabine)治疗高危/复发/难治儿童朗格罕斯细胞组织细胞增生症前瞻性真实世界研究”的 LCH 患者; 3. 首次使用氯法拉滨后皮下注射短效 rhG-CSF 后仍发生 3 级及以上中性粒细胞减少; 4. 预计生存期 3 个月以上; 5. 骨髓造血功能正常,无出血倾向; 6. ECOG 评分为 0-2; 7. 充分理解并遵守本研究的要求,且自愿签署知情同意书。

Inclusion criteria

1. Participants aged between 6 and 18 years; 2. Pediatric patients with LCH enrolled in a prospective real-world study involving Dabrafenib or Trametinib combined with Clofarabine for the treatment of high-risk, recurrent, or refractory LCH; 3. Occurrence of Grade 3 or higher neutropenia following subcutaneous administration of short-acting rhG-CSF after initial chlorpromazine use; 4. Expected survival period exceeding 3 months; 5. Normal bone marrow hematopoietic function and absence of bleeding tendencies; 6. The Eastern Cooperative Oncology Group (ECOG) performance status is between 0 and 2; 7. Participants must fully comprehend and adhere to the study requirements and voluntarily provide informed consent by signing the consent form.

排除标准:

1. 已知对 rhG-CSF、PEG-rhG-CSF 或其辅料过敏者; 2. 没有充分控制的局部或全身感染; 3. 既往有骨髓或造血干细胞移植史; 4. 严重的内脏器官功能障碍(肝功能检查总胆红素(TBIL)、谷丙转氨酶(ALT)、谷草转氨酶(AST)均>5 倍正常值上限;肾功能检查:血清肌酐(Cr)>2 倍正常值上限;合并严重心脑血管、肝脏、肾脏、内分泌和血液等系统原发疾病); 5. 有特殊病原感染者:乙肝患者(HbsAg 阳性且检测 HBV-DNA 提示有病毒复制);丙肝患者(HCV 抗体阳性且检测 HCV-RNA 提示有病毒复制);梅毒筛查阳性(特异性抗体检测阳性,非特异性抗体检测阴性且结合临床判断确证为非活动期感染者除外);已知 HIV 阳性病史或 HIV 筛查阳性; 6. 入组前 4 周内采用同类其他受试药物; 7. 研究者判断不适宜参与的患者。患有其他基础疾病,如原发免疫缺陷病、心功能不全、肾功能不全、肝炎病毒感染、HIV 感染、脏器移植术后等。

Exclusion criteria:

1. Individuals with known allergies to recombinant human granulocyte colony-stimulating factor (rhG-CSF), polyethylene glycol-conjugated rhG-CSF, or their excipients; 2. Presence of local or systemic infections that are inadequately controlled; 3. A history of bone marrow or hematopoietic stem cell transplantation; 4. Severe dysfunction of visceral organs, indicated by liver function tests showing total bilirubin (TBIL), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels exceeding five times the upper limit of normal, or renal function tests showing serum creatinine (Cr) levels greater than twice the upper limit of normal; and the presence of severe primary diseases affecting the cardiovascular, hepatic, renal, endocrine, or hematological systems; 5. Individuals with specific pathogenic infections include: patients diagnosed with Hepatitis B, characterized by HBsAg positivity and HBV DNA detection indicative of viral replication; patients with Hepatitis C, identified by HCV antibody positivity and HCV-RNA detection suggestive of viral replication; individuals with positive syphilis screening, excluding those with positive specific antibody testing, negative non-specific antibody testing, and clinically confirmed as non-active phase infection; and those with a known history of HIV positivity or positive HIV screening results; 6. Within the first four weeks of enrollment, the use of other investigational drugs of the same type is prohibited; 7. Researchers also have the discretion to exclude patients deemed unsuitable for participation due to other underlying conditions, such as primary immunodeficiency, heart failure, kidney failure, hepatitis virus infection, HIV infection, or a history of organ transplant surgery.
