纳入标准:

1.≥18周岁的患者,男女不限。 2.研究眼诊断为中度(2期,即持续性上皮缺损,PED)或重度(3期,即角膜溃疡)NK。 3.研究眼至少有2周的角膜上皮缺损或角膜溃疡史。 4. 研究眼在PED或角膜溃疡区域内及区域外至少一个象限存在角膜知觉减退(Cochet-Bonnet知觉计检测≤40mm)。 5.研究眼对既往一种或多种NK的传统非手术治疗难治(例如:不含防腐剂的人工泪液、凝胶或软膏,停用可降低角膜敏感性的药物,治疗性隐形眼镜等)。 6.研究眼在入组前2周内未发现PED或角膜溃疡改善。 7.从签署知情同意书至末次用药后3 个月内无生育计划(包含捐精和捐卵)且自愿采取有效的非药物避孕措施。 8.自愿参加本试验,经过充分知情,理解并签署知情同意书。

Inclusion criteria

1. Patients aged 18 years or older, regardless of gender. 2. The study eye is diagnosed with moderate (stage 2, i.e., persistent epithelial defect, PED) or severe (stage 3, i.e., corneal ulcer) neurotrophic keratitis (NK). 3. The study eye has a history of corneal epithelial defect or corneal ulcer for at least 2 weeks. 4. The study eye has reduced corneal sensation (measured by Cochet-Bonnet esthesiometer <=40 mm) in at least one quadrant both within and outside the area of PED or corneal ulcer. 5. The study eye is refractory to one or more previous traditional non-surgical treatments for NK (e.g., preservative-free artificial tears, gels or ointments, discontinuation of drugs that reduce corneal sensitivity, therapeutic contact lenses, etc.). 6. No improvement of PED or corneal ulcer was found in the study eye within 2 weeks before enrollment. 7. Have no plans for childbearing (including sperm donation and egg donation) from the signing of the informed consent form until 3 months after the last administration of the drug, and be willing to take effective non-pharmacological contraceptive measures. 8.

随机方法(请说明由何人用什么方法产生随机序列):

筛选合格的受试者由研究者使用交互式网络应答系统(Interactive Web Response System,IWRS)进行随机,分配随机号和试验用药品。本研究20、60 μg/mL两个剂量组先后进行筛选入组,每个剂量组21例,筛选合格的受试者随机进入试验组或安慰剂组(14∶7),每个剂量组13例采集PK样本(试验组和安慰剂组分别为9例和4例),所有受试者先随机接受4周试验药物或安慰剂盲态治疗(盲态治疗期),然后接受4周相应剂量的试验药物治疗(开放标签治疗期)。项目统计师根据试验方案设计随机计划和模拟随机表,随机统计师根据随机计划产生正式的随机表。随机号与不同的治疗组关联,继而与药物编码关联。

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

Eligible subjects identified during the screening process will be randomized by the investigator using the Interactive Web Response System (IWRS), and will be assigned a random number and the investigational drug. In this study, subjects will be screened and enrolled into the two dosage groups of 20 μg/mL and 60 μg/mL successively. There will be 21 subjects in each dosage group. Eligible subjects will be randomly assigned to either the experimental group or the placebo group (in a ratio of 14:7). For each dosage group, PK samples will be collected from 13 subjects (9 subjects from the experimental group and 4 subjects from the placebo group respectively). All subjects will first receive a blinded treatment with the investigational drug or placebo for 4 weeks (the blinded treatment period), and then receive the investigational drug at the corresponding dosage for another 4 weeks (the open-label treatment period). The project statistician will design the randomization plan and the simulated randomization table according to the trial protocol, and the randomization statistician will generate the formal randomization table based on the randomization plan. The random numbers will be associated with different treatment groups, which will in turn be associated with the drug codes.
