鼻内纳米乳剂佐剂重组大流行性流感疫苗在健康成人中的安全性和免疫原性 (IN-NE-rH5)

2026年7月3日 更新者:BlueWillow Biologics

在健康成人中进行 2 剂含和不含纳米乳剂佐剂的鼻内 rH5 流感疫苗随后接种 1 剂肌内 H5N1 疫苗的 Ph1 期随机双盲受控剂量范围安全耐受性和免疫原性研究

该临床试验的目的是评估 BW-1014 的安全性和免疫原性。

BW-1014 是一种纳米乳剂 (NE) 佐剂重组血凝素 5 (rH5),可预防流感大流行。

该研究将在美国一个中心的 40 名年龄在 18 至 45 岁之间的健康成人志愿者中进行。

该研究将比较 3 种不同剂量水平的 rH5(20% NE 佐剂中的 25µg、50µg 和 100µg rH5,使用移液器滴管和 rH5 对照(100µg,无 NE 佐剂)和安慰剂对照(生理盐水)。 研究产品将分 2 剂鼻内 (IN) 给药。 这将在 6 个月后使用获得许可的 H5N1 IIV IM 疫苗。

除了安全性结果外,还将在鼻洗液、血清和血细胞中测试同源和异源免疫学结果。

研究概览

详细说明

本研究是一项单中心、1 期、首次人体、单中心、随机、安慰剂对照、双盲研究,旨在评估主要系列鼻内重组 H5 流感疫苗的安全性、耐受性和免疫原性并且没有纳米乳剂佐剂,然后是加强剂量的获得许可的肌肉注射甲型流感 (H5N1) 疫苗。

参与者将被随机分配到以下 5 个组中的一个:

A. BW-1014:25 微克/20% NE; 8 名参与者。 B. BW-1014:50 µg / 20% NE; 8 名参与者。 C. BW-1014:100 微克/20% NE; 8 名参与者。 D. rH5 对照:100µg; 8 名参与者。 E. 生理盐水(安慰剂); 8 名参与者。 因为这是一项剂量递增试验,我们的研究分为四个阶段,每个阶段都有一个队列接受疫苗。 最多 40 名参与者将根据升级阶段的分配比例随机分配到五个研究组之一。 如果所有参与者都进行疫苗接种,最终的疫苗分配比例将为 1:1:1:1:1。 受试者将在第 1 天和第 29 天接受主要系列的两次研究治疗的鼻内疫苗接种。 受试者剂量将逐步进行。 在为研究组的其余成员接种疫苗之前,以及在为哨兵参与者接种下一个更高剂量的佐剂研究疫苗之前,将在哨兵参与者中评估每剂佐剂研究疫苗。 在收到第一剂疫苗后,将对哨兵参与者进行为期 7 天的跟踪,以确定停止标准和 SMC 数据审查,然后再对研究组的其余成员进行疫苗接种。 随后,所有参与者将在第 197 天接受第三剂肌肉注射异源甲型流感 (H5N1) 疫苗。

在第二次研究治疗疫苗接种后的一年内,将跟踪参与者的安全性和免疫学终点。

除了在整个研究过程中从外周血和鼻洗液中收集的单核细胞的细胞免疫反应外,还将评估参与者是否产生了特定的粘膜和体液抗体。 这些评估将针对同源 H5N1 进化枝 2.1 和异源 H5N1 进化枝 1。
