Safety and Immunogenicity of an Intranasal RSV Vaccine Expressing SARS-CoV-2 Spike Protein (COVID-19 Vaccine) in Adults

August 1, 2022 updated by: Meissa Vaccines, Inc.

Phase 1, Open-Label, Dose-Escalation Study to Evaluate Tolerability, Safety, and Immunogenicity of an Intranasal Live Attenuated Respiratory Syncytial Virus Vaccine Expressing Spike Protein of SARS-CoV-2 in Healthy Adults Ages 18 - 69 Years

This study evaluates an investigational vaccine that is designed to protect humans against infection with SARS-CoV-2, the novel coronavirus causing COVID-19 disease. The investigational vaccine, MV-014-212, is a live attenuated vaccine against respiratory syncytial virus (RSV) that is expressing the spike (S) protein of SARS-CoV-2. MV-014-212 is administered as drops or a spray in the nose. Specifically, this study analyzes the safety of, and the immune response to, the vaccine when administered to healthy adults between the ages of 18 and 69 years who are seronegative to SARS-CoV-2 and have not received a prior vaccine against COVID-19.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 69 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Healthy adults ≥18 and <56 years (Cohort A) and ≥56 years and <70 years (Cohort B) as determined at the day of signing informed consent

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Unsolicited AEs
Time Frame: Immediate post-vaccination period
Frequency of unsolicited AEs will be measured, categorized by severity. Unsolicited AEs are any untoward medical occurrences in a participant administered the investigational vaccine, regardless of causal relationship to the investigational vaccine. Unsolicited AEs can include unfavorable and unintended signs (including abnormal laboratory findings), symptoms, or diseases temporally associated with the use of the investigational vaccine.
Immediate post-vaccination period
Medically attended adverse events (MAEs)
Time Frame: Full study duration, an average of 1 year
Frequency of MAEs will be measured, categorized by vaccine-relatedness. MAEs are AEs, whether considered causally related to the investigational vaccine or not, with unscheduled medically attended visits, such as urgent care visits, acute primary care visits, emergency department visits, or other previously unplanned visits to a medical provider. Scheduled medical visits such as routine physicals, wellness checks, 'check-ups', and vaccinations, are not considered MAEs.
Full study duration, an average of 1 year
Solicited adverse events (AEs)
Time Frame: Immediate post-vaccination period
Frequency of solicited AEs will be measured, categorized by severity. Solicited AEs are predefined AEs that may occur after investigational vaccine administration.
Immediate post-vaccination period
Serious adverse events (SAEs)
Time Frame: Full study duration, an average of 1 year
Frequency of SAEs will be measured, categorized by vaccine-relatedness. SAEs are AEs, whether considered causally related to the investigational vaccine or not, that threaten life or result in any of the following: death, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, or congenital anomaly/birth defect.
Full study duration, an average of 1 year
Change in serum neutralizing antibody titers against vaccine-encoded SARS-CoV-2 S protein
Time Frame: Baseline through Day 29, an average of five (5) weeks
Change in serum neutralizing antibody (nAb) titers against vaccine-encoded SARS-CoV-2 S protein will be measured per participant
Baseline through Day 29, an average of five (5) weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in serum binding antibody concentrations against vaccine-encoded SARS-CoV-2 S protein
Time Frame: Baseline through Day 29, an average of five (5) weeks
Change in serum binding antibody concentrations against vaccine-encoded SARS-CoV-2 S protein will be measured per participant
Baseline through Day 29, an average of five (5) weeks
Potential vaccine virus shedding: frequency
Time Frame: Baseline through Day 29, an average of four (4) weeks
Frequency of any post-vaccination shedding of vaccine virus (as detected by viral culture) will be measured per dosage group and overall
Baseline through Day 29, an average of four (4) weeks
Potential vaccine virus shedding: magnitude
Time Frame: Baseline through Day 29, an average of four (4) weeks
If post-vaccination shedding of vaccine virus is detected by culture, peak viral titer (measured in plaque forming units, PFU) will be measured per dosage group and overall
Baseline through Day 29, an average of four (4) weeks
Potential vaccine virus shedding: duration
Time Frame: Baseline through Day 29, an average of four (4) weeks
If post-vaccination shedding of vaccine virus is detected by culture, duration of shedding (in days) will be measured per dosage group and overall
Baseline through Day 29, an average of four (4) weeks
