详细说明
Defects in the immune cells can hinder the immune system's ability to fight infection. A stem cell transplant can replace non-working immune system cells with a donor's fully functioning immune cells, but if inflammation is present, the immune cells from the donor may not graft successfully. The proposed trial tests whether emapalumab or fludarabine and dexamethasone can help prepare the body to receive a stem cell transplant by reducing inflammation, so that the immune system will be able to produce fully functioning immune cells. Participants will receive emapalumab or a combination of fludarabine and dexamethasone over the course of four days in the hospital prior to a planned transplant procedure.
This study has two study groups:
- Participants in Group A have a high CXCL9, a specific cytokine, level and will receive emapalumab on Days -22, -15, -8, and -1.
- Participants in Group B have a generalized inflammation and will receive fludarabine and dexamethasone from Days -22 to -18 (5 days).
All study participants are eligible to receive one additional emapalumab 3mg/kg in the first 30 days post-transplant if they begin to have CXCL9 levels that are trending up. Participants will receive personalized rATG dosing. Participants will remain in the hospital according to the usual standard of care guidelines for stem cell transplant. Subject status and follow-up examination/data collection will occur on days 0, 7, 14, 21,30, 45, 60, 7, 100, 180, 270, and 365, then quarterly until 3 years post-transplant.

描述
纳入标准:
- 因以下免疫学状况接受首次异基因 HCT 的患者:
- 原发性免疫缺陷治疗联盟 (PIDTC) 定义的原发性免疫调节障碍,伴或不伴遗传病变
- 患有自身炎症性疾病的患者,通过细胞因子和炎症测定证明至少有 1.5 倍 ULN 的测量细胞因子和/或升高的铁蛋白或 ESR > 2 ULN
- 要纳入 emapalumab 组,病变必须与升高的 CXCL9 >1.5 ULN(或已经控制在 JAK 抑制剂上,前提是 CXCL9 水平在 JAK 抑制剂开始前升高)分离到 IFNγ 途径(或其介质) ). 纳入氟达拉滨/地塞米松组需要炎症(如上定义),而不是孤立的 IFNγ/CXCL9 缺陷
- 能够耐受细胞减灭术(基于如下所述的足够器官功能)
- 只要符合其他纳入标准,任何年龄的患者都可以入组:
需要足够的器官功能,定义如下:
- 肝脏:血清胆红素≤ 2 mg/dL,除非良性先天性高胆红素血症。 患有与阵发性睡眠性血红蛋白尿相关的高胆红素血症或与其 PIRD 诊断相关的其他溶血性疾病的患者符合条件。
- 肝脏:除非被认为与疾病相关,否则 AST、ALT 和碱性磷酸酶 < 正常上限的 2.5 倍。 研究者将需要进行临床指示评估,以评估疾病是否与疾病相关或内在肝病。 如果有临床指征,可以在移植前免疫前期之后和调节开始之前进行额外的测试,因为这将提供额外的数据来确认疾病相关与内在肝功能障碍。
- 肾脏:血清肌酐 <1.5 倍正常年龄。 如果血清肌酐超出正常范围,则 CrCl > 50 mL/min/1.73m2 (计算或估计)或 GFR (mL/min/1.72m2) >30% 的年龄预测正常值。
- 按年龄划分的正常 GFR
- 心脏:MUGA 或静息超声心动图显示 LVEF ≥ 50%。
- 肺部:肺功能测试(FEV1 和校正的 DLCO)≥ 50% 预测值(无法完成 PFT 的儿科患者需要室内空气中脉搏血氧仪记录的氧饱和度≥92%)。
适当的性能状态:
- 年龄 ≥ 16 岁:ECOG ≤ 1 或 Karnofsky 70%
- 年龄 < 16 岁:兰斯基 70%
- 每个患者必须愿意作为研究对象参与,并且必须签署知情同意书或法定监护人酌情同意。
排除标准:
- 入组时未控制的感染。
- 既往接受过同种异体 HCT 的患者。
- HIV I/II 和/或 HTLV I/II 的患者血清阳性。
- 怀孕或哺乳的女性。

- 8/8 或 7/8 HLA 在 A、B、C 和 DRB1 位点匹配,如通过 DNA 分析测试的那样。
- 通过 DNA 分析测试 A、B、C 和 DRB1 位点的单倍相合供体
无关捐赠者:
o 根据 DNA 分析测试,8/8 或 7/8 在 A、B、C 和 DRB1 位点匹配。
- 能够根据机构标准为捐赠过程提供知情同意。
