Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.

Primary study objectives

Percentage of participants with adverse events of special interest (AESIs) from study vaccination through the end of the study

Percentage of participants with medically attended adverse events (MAAEs) from study vaccination through the end of the study

Percentage of participants with serious adverse events (SAEs) from study vaccination through the end of the study

Secondary study objectives

Seroresponse rate 28 days after the booster dose, based on neutralizing Ab titers against pseudoviruses bearing S protein from SARS-CoV-2 WT, Omicron, and Delta variants at each collection timepoint

Awards & Highlights

No Placebo-Only Group

All patients enrolled in this study will receive some form of active treatment.

Trial Design

7Treatment groups

Experimental Treatment

Group I: Part B: CV0501 Dose Cohort 7 (6 μg)Experimental Treatment1 Intervention

Part B, designed to comprise 2 single age group cohorts, Group 7a (≥18 to \<65 years old) will start based on the first interim analysis of safety and immunogenicity data, provided that the SRT assesses the 12 μg dose to be immunogenic and safe.

Group II: Part B: CV0501 Dose Cohort 6 (3 μg)Experimental Treatment1 Intervention

Part B, designed to comprise 2 single age group cohorts, Group 6a (≥18 to \<65 years old) will start based on the first interim analysis of safety and immunogenicity data, provided that the SRT assesses the 12 μg dose to be immunogenic and safe.

Group III: Part A: CV0501 Dose Cohort 5 (100 μg, 150 μg or 200 μg)Experimental Treatment3 Interventions

For each of the groups in Cohort 5, Group 5a (younger) and Group 5b (older age), the SRT may recommend a dose specified by the dosing scenarios in the protocol, based on their review of all available safety data. The SRT will use the same approach, independently, to select the dose levels for older participants (Group 5b) and younger participants (Group 5a).

Group IV: Part A: CV0501 Dose Cohort 4 (75 μg or 100 μg)Experimental Treatment2 Interventions

For each of the groups in Cohort 4, Group 4a (younger) and Group 4b (older age),the SRT may recommend a dose specified by the dosing scenarios in the protocol, based on their review of all available safety data. The SRT will use the same approach, independently, to select the dose levels for older participants (Group 4b) and younger participants (Group 4a).

Group V: Part A: CV0501 Dose Cohort 3 (50 μg)Experimental Treatment1 Intervention

For both Group 3a (younger) and Group 3b (older age), initiation of enrollment in the subsequent group at the next dose level for Cohorts 2-5 will depend on SRT review of safety data up to Day 8 from a minimum of 10 participants, from the previous dose level in the same age group.

Group VI: Part A: CV0501 Dose Cohort 2 (25 μg)Experimental Treatment1 Intervention

For both Group 2a (younger) and Group 2b (older age), initiation of enrollment in the subsequent group at the next dose level for Cohorts 2-5 will depend on SRT review of safety data up to Day 8 from a minimum of 10 participants, from the previous dose level in the same age group.

Group VII: Part A: CV0501 Dose Cohort 1 (12 μg)Experimental Treatment1 Intervention

Enrollment will be staggered, beginning with Group 1a (12 μg, younger adults). Initiation of enrollment in Group 1b (12 μg, older adults) will depend on Safety Review Team (SRT) review of safety data up to Day 8 from a minimum of 10 participants in Group 1a.
