Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43857   clinical trials with a EudraCT protocol, of which   7284   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: The number of participants in the baseline period included only participants randomized into Phase 2b or 3 who received at least one dose of CVnCoV or placebo.
    [2] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left.
    Justification: The milestones include Phase 2b and Phase 3 participants as well as participants who rolled over to the Open Label Phase.
    [3] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left.

    Medically-attended AEs were defined as AEs with medically-attended visits that were not routine visits for physical examination or vaccination, such as visits for hospitalization, an emergency room visit, or an otherwise unscheduled visit to or from medical personnel (medical doctor) for any reason. Clinic visits for COVID-19 testing resulting in negative test results were not considered as medically attended visits, if there is no confirmed diagnosis and no prescribed concomitant medication. The Investigator assessed the relationship between trial vaccine and occurrence of each AE. The analysis set used was the safety analysis set (SAS). Participants were censored at the first day after unblinding or at the day after receiving the authorized/licensed vaccine, whichever was earlier.

    Phase 2b Participants Only: Intensity of Solicited AEs as Per Investigator Assessment [10]
    End point description
    Solicited local AEs (injection site pain, redness, swelling, and itching) and solicited systemic AEs (fever, headache, fatigue, chills, myalgia, arthralgia, nausea/vomiting, and diarrhea) were recorded on the day of vaccination and the following 7 days using an eDiary. The Investigator made an assessment of intensity of each solicited AE reported during the trial. Each solicited AE was graded from Mild (Grade 1) to Severe (Grade 3), where higher grades indicated a worse outcome. The analysis set used was the SASsol including only participants who experienced solicited AEs. Participants were censored at the first day after unblinding or at the day after receiving the authorized/licensed vaccine, whichever was earlier.

    Number of Participants Who Experienced a Virologically-confirmed (RT-PCR Positive) Case of COVID-19 of Any Severity With Symptom Onset at Any Time After the First Study Vaccination
    End point description
    case of COVID-19 was defined as follows: • Virologically-confirmed case of COVID-19 (of any severity) defined as a positive SARS-CoV-2 specific RT-PCR test in a person with clinically symptomatic COVID-19. • Symptom onset ≥ 15 days after second trial vaccination. • First episode of virologically-confirmed COVID-19, i.e. the participant must not have had a history of virologically-confirmed COVID-19 illness at enrollment or have had developed a case of virologically-confirmed COVID-19 before 15 days after the second trial vaccination. • Participant was SARS-CoV-2 naïve at baseline and Day 43 (defined as seronegative to N protein in the blood samples collected at baseline and Day 43). This analysis was not completed as different definitions of COVID-19 cases used during blinding, open-label and after implementation of an urgent safety measures letter led to biases that did not permit analysis of COVID-19 cases at the end of the trial.

    End point description
    Titers of IgG antibodies directed against the SARS-CoV-2 RBD of Spike Protein antigen were measured by ELISA and expressed as GMTs with 95% CI. Participants who have tested positive for SARS-CoV-2 via PCR or N-protein antibodies have their data included up to the point of positive test result or symptom onset. Participants who received a licensed/authorized vaccine were censored at the day after receiving the licensed/authorized vaccine. Per Protocol Immunogenicity (PPI) Set: Included all Phase 2b participants from the Immunogenicity Subset who were seronegative at baseline, received both doses as randomized and within the specified windows, had no important protocol deviations that impacted immunogenicity outcomes, did not receive medical treatments that interfered with the proposed immunogenicity measurements and had at least 1 blood sample collected at baseline and starting at 14 days post-second vaccination available for analysis.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    17 Feb 2021
    The following changes were made: • The planned extension study was removed from the protocol for this trial and was submitted as a separate protocol. • Several COVID-19 vaccines have been authorized for emergency use since the original protocol and guidance was added on the handling of participant participation and data from participants who request to be unblinded due to being eligible to receive an authorized/licensed vaccine to prevent COVID-19. • The secondary safety objective was reclassified as a primary objective. • Instructions added that gene sequencing should be performed in participants with a positive RT PCR test to identify mutations in the S protein. • Samples for CMI and genomic biomarkers could also be taken in Phase 3 and not only in the Phase 2b immunogenicity subset. • It was clarified throughout the protocol that: - COVID-19 is not to be reported as an AE. - Different types of AEs, and any concomitant medication used for the treatment therefore, should only be collected during the specified reporting periods. - Participants may receive the second dose if they develop COVID 19 between the first and second doses (after being symptom-free for 2 weeks).
    29 Mar 2021
    The following changes were made: • The co-primary objective (and corresponding endpoint) regarding the efficacy of CVnCoV in the prevention of moderate to severe COVID 19 was changed to a key secondary objective. Subsequently, the corresponding statistical calculations were also updated. • Various strains have been identified since the original protocol and therefore a key secondary efficacy objective was added to demonstrate the efficacy of CVnCoV in the prevention of COVID 19 caused by the “wild type” (ie, WT/D614G lineages A.1/B.1 without VOC B.1.1.7, B.1.351, B.1.429) and “UK” (B.1.1.7) strains. An exploratory objective was added to demonstrate the efficacy on any other strains was also added. • The number of participants with exploratory immunogenicity assessment decreased from 400 to 200.
    25 Nov 2021
    The following changes were made: • To unblind all remaining blinded participants and inform them of the treatment received. • To monitor safety of the following participants remaining in the open-label phase after unblinding: - Participants who had received CVnCoV and received/would receive an AV through their national vaccination program. - Participants who had received CVnCoV and continued follow-up in the trial as initially planned, without receiving an AV.
