研究目的:

1.主要目的 评估利奈唑胺相较于标准治疗注射用青霉素钠治疗在实现神经梅毒的临床、脑脊液及血清学复合治愈终点的非劣效性。 2.次要目的 (1)评估利奈唑胺与注射用青霉素钠治疗相比的临床、脑脊液和血清学治愈率。 (2)评估利奈唑胺与标准注射用青霉素钠治疗相比的临床、脑脊液和血清学方面的治愈时间进程。 评估利奈唑胺治疗与标准注射用青霉素钠相比治疗神经梅毒的安全性。 (3)评估随机分配至利奈唑胺组的18名参与者体内利奈唑胺的药代动力学(PK)参数,包括基于实测药代动力学特征数据得出的 24 小时曲线下面积(AUC24h)及脑脊液与血药浓度比。 3.探索性目的: (1)鉴定梅毒螺旋体与神经梅毒临床表现相关的基因组学特征(基因组学)。 (2)鉴定与神经梅毒临床表现相关的抗原及宿主对梅毒螺旋体的体液免疫应答(蛋白质组学)。 (3)获取生物样本用于进一步研究。  

Objectives of Study:

1. Primary objectives To assess the non-inferiority of linezolid compared with standard ACPG treatment in achieving composite clinical, Cerebrospinal fluid(CSF), and serological cure of neurosyphilis. 2. Secondary objectives (1) To assess the rates of CSF, serological, and clinical cure of linezolid compared with standard ACPG treatment. (2) To assess the time course of clinical, CSF and serological cure of linezolid compared with standard ACPG treatment. (3) To characterize the pharmacokinetic (PK) parameters of linezolid in a subset of participants, including AUC24h and CSF: blood ratio derived from observed pharmacokinetic profile data. 3. Exploratory objectives (1) To identify genomic traits of TP that are associated to neurosyphilis clinical manifestations (genomics). (2) To identify antigens and host humoral response to TP that are associated to neurosyphilis clinical manifestations (proteomics). (3) Biological samples will be obtained for further studies.

纳入标准:

Inclusion criteria

排除标准:

1.已知对利奈唑胺、青霉素和/或赋形剂过敏,尤其是已知对青霉素、头孢菌素或其他β-内酰胺药物过敏和/或对大豆或花生过敏。 2.乳糖或半乳糖不耐症或葡萄糖-半乳糖吸收不良。 3.妊娠期或哺乳期妇女,或随访期间怀孕。 4.目前正在接受治疗的药物可能与研究药物发生相互作用(见研究计划的附录表2)。 5.在首次服用研究药物前至少30天或5个半衰期(以较长者为准)接受过任何研究性化学或生物制剂治疗,或目前正在参加另一项干预性临床研究。 6.在随机分组前 1 周内服用过任何具有潜在抗梅毒螺旋体活性的抗生素例如β内酰胺类(如青霉素及头孢菌素类)、大环内酯类、四环素类,或在随机分组前 2 周内肌肉注射过青霉素。 7.骨髓抑制,定义为出现以下任一情况: o 绝对中性粒细胞计数(ANC)<1,000/μL o 血红蛋白<9 g/dL o 血小板计数<100,000/μL 8.医生认为MRI 或其他检查结果提示参与者的症状存在与神经梅毒无关的其他潜在病因。 9.认知功能受损、意识模糊状态,或经医生判断存在其他可能导致无法提供有效知情同意或无法依从研究程序的情况。 10.重度免疫抑制:具体包括:①晚期HIV感染者(即患有艾滋病界定疾病者);②当前正在接受化疗者;③正在接受全身性皮质类固醇治疗、且剂量相当于泼尼松≥20毫克/天、持续超过2周者。设定此项排除标准,旨在最大程度降低参与者的安全风险,并避免因免疫状态差异对免疫反应及治疗结果的评估造成混杂效应。然而,HIV感染已得到控制者(即接受抗逆转录病毒治疗病情稳定,且病毒载量检测不到)可被纳入研究;因为已有公开证据表明,此类患者对于神经梅毒治疗的临床反应与普通患者相当。 11.活动性或未充分治疗的肺结核。 12.当前或过去一年内有晚期恶性肿瘤病史。 13.高血压未控制的患者、嗜铬细胞瘤或甲状腺功能亢进症患者。

Exclusion criteria:

1. Known allergy to linezolid, penicillin, and/or excipients, particularly known hypersensitivity to penicillin, cephalosporins, or other beta-lactam agents and/or allergy to soya or peanut. 2. Lactose or galactose intolerance or glucose-galactose malabsorption. 3. Pregnant or breastfeeding women, or willing to be pregnant during the follow-up period. 4. Current treatment with any drugs likely to interact with the study medication (see list in Appendix 2 of the research protocol). 5. Have been treated with any investigational chemical or biologic agent or currently enrolled in another interventional clinical study for at least 30 days or 5 half-lives (whichever is longer) prior to the first dose of study drug. 6. Have taken any antibiotics with potential activity against syphilis (e.g. beta lactams, cephalosporines, macrolides, tetracyclines) within 1 week prior to randomization or have been administered intramuscular penicillin within 2 weeks prior to randomization. 7. Myelosupression, defined as any of the following: o Absolute neutrophil count (ANC) < 1,000 cells/μL o Hemoglobin < 9 g/dL o Platelet count < 100,000 cells/μL 8. In the physician's opinion, the Magnetic Resonance Imaging (MRI) or other tests conducted reveal a potential alternative cause for the participant's symptoms that are unrelated to neurosyphilis. 9. Cognitive impairment, confusional state or any other process that, in the physician’s opinion, prevents from providing valid informed consent or from adequately complying with study procedures. 10. Severe immunosuppression: Specifically, ①individuals with advanced HIV infection (AIDS-defining illness);②current chemotherapy;③systemic corticosteroid therapy equivalent to ≥20 mg/day of prednisone for >2 weeks. Exclusion aims to minimize safety risks and to avoid confounding effects on immune response and treatment outcomes. Patients with controlled HIV infection (stable on ART and undetectable viral load) may be included, as this group has comparable clinical responses to neurosyphilis therapy based on published evidence. 11. Active or inadequately treated tuberculosis. 12. Current or past history (in the last year) of advanced malignancy 13. Uncontrolled hypertension, pheochromocytoma or hyperthyroidism

随机方法(请说明由何人用什么方法产生随机序列):

随机序列由独立统计学家预先生成,并通过交互式网络应答系统(IWRS)进行管理和执行。以1:1比例将参与者随机分组,每个区组包含6名参与者。

Randomization Procedure (please state who generates the random number sequence and by what method):

The randomization sequence was pre-generated by an independent statistician and executed through an Interactive Web Response System (IWRS), with all procedures recorded in the audit trail. Randomization will be done in a 1:1 ratio with six participants per block.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

由于干预组和对照组的给药方式、给药途径和治疗持续时间存在显著差异,因此无法进行盲法。但统计学分析将采用盲法。统计学家将不知道参与者被分配到哪个治疗组。

Blinding:

Blinding will not be carried out because the dosing, routes of administration, and treatment durations of the intervention and control groups are significantly different. However, the statistical analysis will be blinded. The statistician will not know which treatment group the participant has been allocated to.
