Study to Evaluate the Safety, Tolerability, and Immunogenicity of an RNA Vaccine Candidate Against COVID-19 in Healthy Japanese Adults
Study Details
Study Description
Brief Summary
This is a Phase 1/2, randomized, placebo-controlled, and observer-blind study in healthy Japanese adults.
The study will evaluate the safety, tolerability, and immunogenicity of the SARS-CoV-2 RNA vaccine candidate against COVID-19:
-
As 2 doses, separated by 21 days
-
At a single dose level
-
In adults 20 to 85 years of age

Outcome Measures
Primary Outcome Measures

- Percentage of participants reporting systemic events [For 7 days after dose 1 and dose 2]
Fever, fatigue, headache, chills, vomiting, diarrhea, new or worsened muscle pain, and new or worsened joint pain as self-reported on electronic diaries.
- Percentage of participants reporting adverse events [From dose 1 through 1 month after the last dose]
As elicited by investigational site staff

As measured at the central laboratory
- GMFR in SARS-CoV-2 serum neutralizing titers from before vaccination to each subsequent time point [Through 1 year after dose 2 from baseline]
As measured at the central laboratory
- SARS-CoV-2 S1-binding IgG levels, expressed as GMCs [Through 1 year after dose 2]
As measured at the central laboratory

As measured at the central laboratory
- GMR of the geometric mean of SARS-CoV-2 serum neutralizing titers to the geometric mean of SARS CoV 2 S1-binding IgG levels [Through 1 year after dose 2]
As measured at the central laboratory
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Japanese male or female participants between the ages of 20 and 85 years, inclusive, at randomization.
-
Participants who are willing and able to comply with all scheduled visits, vaccination plan, laboratory tests, lifestyle considerations, and other study procedures.
-
Healthy participants who are determined by medical history, physical examination, and clinical judgment of the investigator to be eligible for inclusion in the study.
-
Capable of giving personal signed informed consent.
Exclusion Criteria:
-
Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.
-
Known infection with human immunodeficiency virus (HIV), hepatitis C virus (HCV), or hepatitis B virus (HBV).
-
History of severe adverse reaction associated with a vaccine and/or severe allergic reaction (eg, anaphylaxis) to any component of the study intervention(s).
-
Receipt of medications intended to prevent COVID-19.
-
Previous confirmed diagnosis of COVID-19.
-
Immunocompromised individuals with known or suspected immunodeficiency, as determined by history and/or laboratory/physical examination.
-
Bleeding diathesis or condition associated with prolonged bleeding that would, in the opinion of the investigator, contraindicate intramuscular injection.
-
Women who are pregnant or breastfeeding.
-
Previous vaccination with any coronavirus vaccine.
-
Individuals who receive treatment with immunosuppressive therapy, including cytotoxic agents or systemic corticosteroids, eg, for cancer or an autoimmune disease, or planned receipt throughout the study.
-
Receipt of blood/plasma products or immunoglobulin, from 60 days before study intervention administration or planned receipt throughout the study.
-
Participation in other studies involving study intervention within 28 days prior to study entry and/or during study participation.
-
Previous participation in other studies involving study intervention containing lipid nanoparticles.
-
Subset only: Any screening hematology and/or blood chemistry laboratory value that meets the definition of a ≥ Grade 1 abnormality.
-
Investigator site staff or Pfizer employees directly involved in the conduct of the study, site staff otherwise supervised by the investigator, and their respective family members.
