COVID-19 Variant Immunologic Landscape Trial (COVAIL Trial)

NCT ID: NCT05289037

Last Updated: 2025-10-17

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 1270 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2022-03-30
• Study Completion Date: 2023-11-27

Brief Summary

This phase 2 clinical trial will evaluate the safety and immunogenicity of additional doses of prototype and variant (alone or in combination) vaccine candidates in previously vaccinated participants with or without prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and will evaluate innate, cellular, and humoral immune responses to inform on how to shift the immune response to cover new variants as they emerge. A randomized open-label, non-placebo controlled, multi-site, multi-stage clinical trial in individuals, 18 years of age and older, who are in a stable state of health, has received a complete authorized/approved vaccine series (primary series + booster either with homologous or heterologous vaccine products) >/ = 16 weeks prior to enrollment. Subjects will be stratified by i) age (18-64 years and = 65 years of age) (however arms 16 and 17 or stage 4 will only enroll participants between the ages of 18-49 years) and ii) history of confirmed prior SARS-CoV-2 infection, and randomly assigned to receive one of several variant vaccines. Enrollment will target a goal of approximately 45% of each of the variant vaccine arms to be in older adults (= 65 years of age) for stages 1, 2 and 3 and approximately 20% to have had confirmed COVID-19 for all 4 stages. The primary objective is to evaluate humoral immune responses of candidate SARS-CoV-2 variant vaccines, alone or in combination.

Detailed Description

This phase 2 clinical trial will evaluate the safety and immunogenicity of additional doses of prototype and variant (alone or in combination) vaccine candidates in previously vaccinated participants with or without prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and will evaluate innate, cellular, and humoral immune responses to inform on how to shift the immune response to cover new variants as they emerge. A randomized open-label, non-placebo controlled, multi-site, multi-stage clinical trial in individuals, 18 years of age and older, who are in a stable state of health, has received a complete authorized/approved vaccine series (primary series + booster either with homologous or heterologous vaccine products) >/= 16 weeks prior to enrollment. Subjects will be stratified by i) age (18-64 years and = 65 years of age) (however arms 16 and 17 or stage 4 will only enroll participants between the ages of 18-49 years) and ii) history of confirmed prior SARS-CoV-2 infection, and randomly assigned to receive one of several variant vaccines. Enrollment will target a goal of approximately 45% of each of the variant vaccine arms to be in older adults (= 65 years of age) for stages 1, 2 and 3 and approximately 20% to have had confirmed COVID-19 for all 4 stages. This is an adaptive design and may add arms of new vaccine platforms and/or variant lineage spike vaccines as needed. The study arms will be conducted in different stages (that could overlap) depending on public health needs and the availability of study products (starting with the available mRNA vaccines). The primary objective is to evaluate humoral immune responses of candidate SARS-CoV-2 variant vaccines, alone or in combination. The secondary objective is to evaluate the safety of candidate SARS-CoV-2 variant vaccines, as assessed by: a) Local and systemic solicited Adverse Events for 7 days following each vaccine dose; b) Unsolicited Adverse Events from Dose 1 to 28 days following each vaccine dose; c) Serious Adverse Events (SAEs), Medically Attended Adverse Events (MAAEs), Adverse Events of Special Interests (AESIs), New Onset of Chronic Medical (NOCMCs) and Adverse Events (AEs) leading to withdrawal from the study from Dose 1 to 12 months after last vaccine dose.
