Group:

Sample size:

干预措施:

按照患者纳入的先后顺序,将先纳入的3名患者以标准治疗方案联合预先指定的YMN-1A1疫苗起始剂量进行治疗。在低剂量组中,患者单次剂量为15 μg/次,第0、14、28、56天肌肉注射YMN-1A1疫苗制剂,共给药4次。在剂量限制性毒性(Dose-limited toxicity, DLT)观察期内(28天),观察3名患者中发生DLT的例数,以此判断是否维持当前剂量组或是调整剂量组。若满足剂量递增的条件,再招募更多参与者接受高剂量,每位受试者只接受一个相应的剂量,患者单次剂量为15 μg/次或30 μg/次或60 μg/次,每个剂量均为200 μL,第0、14、28、56天肌肉注射YMN-1A1疫苗制剂,共给药4次。

干预措施代码:

Intervention:

According to the order of patient inclusion, the first three included patients were treated with the standard treatment regimen combined with the pre-specified starting dose of the YMN-1A1 vaccine. In the low-dose group, patients received a single dose of 15 μg each time. The MN-1A1 vaccine formulation was intramuscularly injected on days 0, 14, 28, and 56 for a total of 4 doses. During the dose-limited toxicity (DLT) observation period (28 days), the number of cases of DLT among the 3 patients was observed to determine whether to maintain the current Dose group or adjust the dose group. If the conditions for dose escalation are met, more participants will be recruited to receive a high dose. Each subject will only receive one corresponding dose. The single dose for patients is 15 μg/ time or 30 μg/ time or 60 μg/ time, and each dose is 200 μ L. The MN-1A1 vaccine preparation will be intramuscularly injected on days 0, 14, 28, and 56 for a total of 4 doses.
