干预措施:

侧脑室注射腺相关病毒载体RF003注射液。剂量爬坡阶段:约 9-15 名患者,用于探索低、中、高 3 个剂量的安全范围起始剂量为低剂量,基于临床前毒理学数据(NOAEL - 未观察到不良反应水平)转化计算,留有充足安全余量。每个剂量水平对应 1 个队列,每个队列纳入 3 名对应年龄组的患者。低剂量队列设置 4-8 周核心安全观察期,重点监测急性期反应(发热、脑脊液细胞增多等)、早期免疫反应;中、高剂量队列沿用该观察期,同步关注器官毒性风险。待低剂量的 3 名患者完成观察期后,基于安全数据决策:无 DLT(剂量限制性毒性)且无一致严重不良事件:递增至下一个剂量水平(低→中→高)。出现 1 例 DLT:该剂量水平扩展至 6 名患者;若 6 人中 DLT≤1 例,继续爬坡;若≥2 例,停止爬坡,前一剂量为 MTD(最高耐受剂量)。出现≥2 例 DLT:立即停止该剂量入组,MTD 为前一剂量水平。3 个剂量水平,每个队列平均 3-5 人(含可能扩展),共 9-15名患者。

干预措施代码:

Intervention:

Adeno-associated viral vector RF003 injection was injected into the lateral ventricle. Dose climbing stage: about 9-15 patients were used to explore the safe range of low, medium and high doses. The starting dose was low dose, and there was sufficient safety margin based on the transformation of preclinical toxicology data (NOAEL - no observed adverse effect level). Each dose level corresponded to one cohort, and each cohort included three patients in the corresponding age group. A core safety observation period of 4-8 weeks was set for the low-dose cohort, focusing on the monitoring of acute phase reactions (fever, pleocytosis in cerebrospinal fluid, etc.) and early immune response. The same observation period was used for the medium-dose and high-dose cohorts, with attention paid to the risk of organ toxicity. After the three patients in the lower dose completed the observation period, the decision was made based on the safety data: no DLT (dose-limiting toxicity) and no consistent serious adverse events: escalation to the next dose level (low → medium → high). One DLT occurred: this dose level was extended to six patients; If DLT<=1 case in 6 people, continue climbing. If >=2 cases, the climbing was stopped, and the previous dose was MTD (maximum tolerated dose). If >=2 DLTS occurred, enrollment at that dose was stopped immediately, and MTD was the previous dose level. Three dose levels, an average of 3-5 patients per cohort (with potential expansion), and a total of 9-15 patients.

Sample size:

干预措施:

侧脑室注射腺相关病毒载体RF003注射液。剂量扩展队列:约 15-21 名患者,用于在初步确定的安全有效剂量下,进一步评估安全性与初步疗效。在爬坡阶段确定的 1-2 个安全且有潜力的剂量下,纳入更多患者,获取更可靠的安全性数据与初步疗效证据。队列 A(推荐剂量):入组 10-14 名对应年龄组患者,采用该年龄组高剂量给药。队列 B(探索剂量):入组 5-7 名对应年龄组患者,采用该年龄组中剂量给药。重点评估安全性:不良事件发生率、严重程度等;临床疗效:脑电图变化、癫痫发作频率减少比例、无发作天数等。

干预措施代码:

Intervention:

Adeno-associated viral vector RF003 injection was injected into the lateral ventricle. Dose expansion cohort: approximately 15-21 patients for further evaluation of safety and preliminary efficacy at doses initially determined to be safe and effective. At 1-2 safe and potential doses determined in the climbing phase, more patients will be enrolled to obtain more reliable safety data and preliminary efficacy evidence. Cohort A (recommended dose) : Enroll 10-14 patients in the same age group and use the high dose for that age group. Cohort B (exploratory dose) : Enroll 5-7 age-matched patients at the mid-age-group dose. The focus was on safety: the incidence and severity of adverse events. Clinical efficacy: electroencephalogram changes, proportion of seizure frequency reduction, seizure free days, etc.
