A Study to Investigate the Safety, Immunogenicity of Bivalent mRNA Vaccine RQ3027 and RQ3025 as a Booster Dose in Healthy Adults

January 23, 2024 updated by: Jia Wei, Affiliated Hospital of Yunnan University

An Interventional, Randomized, Parallel Controlled, Investigator Initiated Study to Investigate the Safety, Immunogenicity of Bivalent RQ3027 and RQ3025 mRNA Vaccine as a Booster Dose in 3 Doses COVID-19 Vaccine-Experienced Healthy Adults

This clinical trial aimed to gather safety and immunogenicity data in COVID-19 vaccine-experienced healthy adults. The main questions it aims to answer are:

  • The neutralizing antibodies levels of bivalent mRNA vaccines RQ3027(Alpha/Beta+Omicron XBB.1.5) and RQ3025(Alpha/Beta+Omicron BA.2/4/5) and monovalent mRNA vaccine RQ3013 against the current SARS-CoV-2 circulating variant.
  • The safety profile of RQ3027 and RQ3025 given as a second booster dose to COVID-19 vaccine-experienced participants 18 through 55 years of age.
  • Explore the protective efficacy by documenting confirmed COVID-19 cases after vaccination.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

  • Adult

Accepts Healthy Volunteers

Yes

  • Participants 18 through 55 years of ages.
  • Participants who have received at least 3 doses COVID-19 vaccine.
  • Participants with the last prior dose being 90 or more days before Visit 1(Day 0) or recovered from COVID-19 at least 28 days.
  • Participants able to comply with all scheduled visits, laboratory tests and investigator's instruction.

Exclusion Criteria:

  • Women who are pregnant or breastfeeding.
  • Enrolling in or planning to participate other interventional clinical study.
  • Has received systemic immunoglobulins or blood products within 3 months prior to the day of screening.
  • History of anaphylaxis, urticaria, or other significant adverse reaction requiring medical intervention after receipt of a vaccine.
  • Bleeding disorder considered a contraindication to intramuscular injection or phlebotomy.
  • Continued using anticoagulants such as coumarin and related anticoagulants (i.e., warfarin) or oral anticoagulants (i.e., apixaban, rivaroxaban, dabigatran, and edoxaban).
