在 18 岁及以上成人中针对 COVID-19 的单价和二价重组蛋白疫苗的研究 (VAT00008)
一项平行组、III 期、多阶段、改良双盲、多组研究,以评估两种 SARS-CoV-2 佐剂重组蛋白疫苗(单价和二价)预防 COVID 的功效、安全性和免疫原性-19 在 18 岁及以上的成年人中作为主要系列和开放标签扩展,以评估单价加强剂量的 SARS-CoV2 佐剂重组蛋白疫苗的免疫原性、安全性和功效
这项 III 期研究的目的是评估两种 CoV2 preS dTM-AS03 疫苗(单价和二价)的有效性、安全性和免疫原性,作为多阶段方法初级系列疫苗接种的一部分,以及加强注射CoV2 preS dTM-AS03 疫苗,适用于 18 岁及以上的成年人。
计划总共招募大约 21046 名参与者(第 1 阶段每个研究干预组 5080 人,第 2 阶段每个研究干预组 5443 人)。
初始、双盲、初级系列研究设计计划在每个参与者的最后一次初始注射后 365 天(即,总共大约 386 天)进行。
根据研究监督小组的决定,第 1 阶段和第 2 阶段的参与者将被邀请参加非盲交叉/助推器研究设计,持续时间如下:
- 对于最初接种疫苗的参与者:加强后 12 个月(即大约 18 至 24 个月)
- 对于最初接受安慰剂的参与者:主要系列的最后一剂后 ≥ 4 个月 + 加强剂后 12 个月(即,大约 28 至 34 个月)
- 对于不同意继续研究的非盲交叉/助推器部分的参与者,将停止所有研究程序并且参与者将停止研究。

An SAE was defined as any AE that at any dose resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, or was an important medical event.
An AESI (serious or non-serious) was 1 of scientific and medical concern specific to the Sponsor's study intervention or program, for which ongoing monitoring and rapid communication by the Investigator to the Sponsor could be appropriate.
An MAAE was a new onset or a worsening of a condition that prompted the participant or participant's parent/guardian to seek unplanned medical advice at a physician's office or Emergency Department.

Responders are participants who had baseline values below lower limit of quantification (LLOQ) with quantifiable neutralization titer above assay LLOQ at each pre-defined post-vaccination timepoint and participants with baseline values above LLOQ with a 4-fold increase in neutralizing antibody titers at each pre-defined post-vaccination timepoint.

Stage 1: Number of Participants With >=2-Fold and >=4-Fold Rise in Neutralizing Antibody Titers Against SARS-CoV-2 D614G Strain at Days 22 and 43
大体时间:Pre-vaccination on Day 1 and post-vaccination on Days 22 and 43
|
Neutralizing antibodies activity against SARS-CoV-2 D614G strain was measured with serum neutralization assay (monogram assay).
Participants with neutralization antibody titers >=2-fold and >=4-fold increase from baseline (pre-vaccination) are reported.

Number of Participants With Symptomatic COVID-19 Episodes
大体时间:Stages 1 and 2: From first dose of study vaccine administration (Day 1) up to Day 387. Crossover and Booster: From first dose of study vaccine administration (Day 1) up to Day 487
|
Symptomatic COVID-19 is defined as virologically-confirmed SARS-CoV-2 infection accompanied by protocol-defined CLI.
Grade 1: A type of AE that was usually transient and required only minimal treatment or therapeutic intervention and did not generally interfere with usual activities of daily living.
Grade 2: A type of AE that was usually alleviated with additional therapeutic intervention and interfered with usual activities of daily living, causing discomfort but posed no significant or permanent risk of harm to the research participant.
Grade 3: A type of AE that interrupted usual activities of daily living, or significantly affects clinical status, or required intensive therapeutic intervention.

Stages 1 and 2: From first dose of study vaccine administration (Day 1) up to Day 387. Crossover and Booster: From first dose of study vaccine administration (Day 1) up to Day 487

Number of Participants With COVID-19 Severity Using a 7-Point Ordinal Scale
大体时间:Stages 1 and 2: From first dose of study vaccine administration (Day 1) up to Day 387. Crossover and Booster: From first dose of study vaccine administration (Day 1) up to Day 487
|
The COVID-19 severity scale was based on the 7-point ordinal scale of clinical assessments: 1: death; 2: hospitalized, on invasive mechanical ventilation or extracorporeal membrane oxygenation; 3: hospitalized, on non-invasive ventilation or high flow oxygen devices; 4: hospitalized, that required supplemental oxygen; 5: hospitalized, that did not require supplemental oxygen- discharged but required ongoing medical care (COVID-19 related or otherwise); 6: hospitalized, that did not require supplemental oxygen discharged without ongoing medical care; 7: not hospitalized.

Stages 1 and 2: From first dose of study vaccine administration (Day 1) up to Day 387. Crossover and Booster: From first dose of study vaccine administration (Day 1) up to Day 487

Number of Deaths Associated With COVID-19
大体时间:Stages 1 and 2: From first dose of study vaccine administration (Day 1) up to Day 387. Crossover and Booster: From first dose of study vaccine administration (Day 1) up to Day 487
|
Death associated with COVID-19 was defined as death in a participant with COVID-19 who died within 28 days of the first positive specimen date or who died more than 28 days after the first specimen date and COVID-19 was mentioned as an immediate or underlying cause of death on the death certificate.
