Trial Outcomes & Findings for A Study to Evaluate the Safety, Reactogenicity and Immunogenicity of Vaccine CVnCoV in Healthy Adults for COVID-19 (NCT NCT04449276)

NCT ID: NCT04449276

Last Updated: 2023-01-30

Results Overview

Grade 3 refers to the highest grading on the FDA toxicity scale where a higher grade indicates a worse outcome. An SAE was defined as any untoward medical occurrence that, at any dose: * Resulted in death. * Was life-threatening. * Required inpatient hospitalization or prolongation of existing hospitalization. * Resulted in persistent disability/incapacity. * Was a congenital anomaly/birth defect in the offspring of the participant. * Was an important medical event.

PRIMARY outcome

Timeframe: Up to 24 hours after vaccination on Day 1

Population: Only participants with available data were used for this analysis.

Grade 3 refers to the highest grading on the FDA toxicity scale where a higher grade indicates a worse outcome. An SAE was defined as any untoward medical occurrence that, at any dose: * Resulted in death. * Was life-threatening. * Required inpatient hospitalization or prolongation of existing hospitalization. * Resulted in persistent disability/incapacity. * Was a congenital anomaly/birth defect in the offspring of the participant. * Was an important medical event.

Population: Per the statistical analysis plan for this endpoint, the overall number of participants analyzed includes all randomized participants to show the rate of grade 1, 2, and 3 events in the entire analysis set.

Reactogenicity was assessed daily via collection of solicited local AEs (injection site pain, redness, swelling, and itching) using paper diary cards. Intensity of solicited local AEs and solicited systemic AEs were graded per the FDA Toxicity Grading Scale at Grades 1-3, where higher grades indicate a worse outcome.

Diaries were used for collection of unsolicited AEs on each vaccination day and the following 28 days. In addition, participants were contacted by phone to verify whether they had any health concerns since the last visit. Participants were included only once, at the maximum severity. The Investigator made an assessment of intensity for each AE reported during the trial and assigned it to one of the following categories: * Mild: an event that was easily tolerated by the participant, causing minimal discomfort and not interfering with everyday activities. * Moderate: an event that caused sufficient discomfort to interfere with normal everyday activities. * Severe: an event that prevented normal everyday activities.

Population: Per the statistical analysis plan for this endpoint, the overall number of participants analyzed includes all randomized participants to show the number of participants with one or more SAEs considered related to trial vaccine in the entire analysis set.

An SAE was defined as any untoward medical occurrence that, at any dose: * Resulted in death. * Was life-threatening. * Required inpatient hospitalization or prolongation of existing hospitalization. * Resulted in persistent disability/incapacity. * Was a congenital anomaly/birth defect in the offspring of the participant. * Was an important medical event.

Population: Participants who received at least 1 dose of trial vaccine and for whom the baseline blood sample and at least one additional blood sample are available for analysis (Immunogenicity Set).

Measured using Enzyme-Linked Immunosorbent Assay (ELISA). In participants who did not get exposed to SARS-CoV-2 before the trial or during the trial before the applicable sample was collected, as measured by ELISA to SARS-CoV-2 N-antigen, seroconversion is defined as an increase in titer in antibodies against SARS-CoV-2 spike protein versus baseline. In subjects seropositive for SARS-CoV-2 at baseline, seroconversion is defined as a 2-fold increase in titer in antibodies against SARS-CoV-2 spike protein versus baseline.

SECONDARY outcome

Timeframe: Day 8, Day 15, Day 29, Day 36, Day 43, Day 57, Day 120 and Day 211

Population: Participants who received at least 1 dose of trial vaccine and for whom the baseline blood sample and at least one additional blood sample are available for analysis (Immunogenicity Set).

Measured using an activity assay. In participants who did not get exposed to SARS-CoV-2 before the trial or during the trial before the applicable sample was collected, as measured by ELISA to SARS-CoV-2 N-antigen, seroconversion is defined as an increase in titer in SARS-CoV-2 neutralizing antibodies versus baseline. In participants seropositive for SARS-CoV-2 at baseline, seroconversion is defined as a 2-fold increase in titer in SARS-CoV-2 neutralizing antibodies versus baseline.
