A woman is considered of child-bearing potential unless post-menopausal or surgically sterilized. (Acceptable contraception methods are restricted to barrier contraceptives which include Food and Drug Administration (FDA)-approved spermicides, intrauterine contraceptive devices, or licensed hormonal products.)
  • Read, signed and dated Informed Consent Form.

Who cannot join

  • Pregnant or breast-feeding women.
  • Uncontrolled serious infection i.e., not responding to antimicrobial therapy.
  • History of or active autoimmune disease. Persons with vitiligo or thyroid disease taking thyroid replacement are not excluded.
  • Known or suspected impairment of immunologic function including, but not limited to, clinically significant liver disease; uncontrolled diabetes mellitus; moderate to severe kidney impairment or post organ transplant subjects.
  • History of malignancy, other than squamous cell or basal cell skin cancer, unless there has been surgical excision that is considered to have achieved cure.
  • History of coronary heart disease, myocardial infarction, angina, congestive heart failure, cardiomyopathy, stroke or transient ischemic attack, uncontrolled high blood pressure, or any other heart condition under the care of a doctor.

  • History of allergies or reactions to eggs, egg products, or gentamycin.
  • Having received any vaccinations or planned vaccinations with a live vaccine within 28 days or a killed vaccine within 14 days prior to or after IMVAMUNE®vaccination.
  • Chronic administration (defined as more than 6 days) of systemic corticosteroids within 30 days of the first planned vaccination.
  • Use of any investigational or non-registered drug or vaccine other than IMVAMUNE® within 30 days preceding the first vaccine dose.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • IMVAMUNE®Biological

    IMVAMUNE® liquid -frozen, containing 1 x 10E8 TCID50 MVA-BN® per 0.5 mL dose

Study groups in NCT03472014
Study groupRoleWhat they receive
IMVAMUNE®ExperimentalTwo subcutaneous vaccinations with 0.5 mL IMVAMUNE® vaccine administered at a 4 week intervals
Receives: Biological: IMVAMUNE®

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. ELISA Seropositivity Rate

    Seropositivity rate based on vaccinia-specific Enzyme-linked Immunosorbent Assay (ELISA). Seropositivity is defined as antibody titers ≥ detection limit (50). Percentages based on number of subjects with data available.

    Measured: up to Week 7

Secondary outcomes (5)
  1. ELISA Seroconversion Rate

    Seroconversion rate based on Enzyme-linked Immunosorbent Assay (ELISA). Seroconversion is defined as the appearance of antibody titers ≥ detection limit (50) for initially seronegative subjects, or a doubling or more of the antibody titer compared to the Screening titer for initially seropositive subjects. Percentages based on number of subjects with data available.

    Measured: Week 7

  2. ELISA GMT

    Geometric Mean Titers (GMT) based on vaccinia-specific Enzyme-linked Immunosorbent Assay (ELISA). Titers below the detection limit are included with a value of '1'.

    Measured: up to Week 7

  3. Serious Adverse Events

    Incidence, relationship and intensity of any Serious Adverse Event (SAE).

    Measured: up to 32 weeks

  4. Related Grade >=3 Adverse Events

    Incidence of any Grade >=3 Adverse Events possibly, probably or definitely related to the trial vaccine

    Measured: within 29 days after any vaccination

  5. Non-serious AEs

    Incidence of non-serious AEs

    Measured: within 29 days after any vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing IMVAMUNE® in people with Vaccination, run by Bavarian Nordic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Aug 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

ELISA Seropositivity Rate (time frame: up to Week 7). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Aug 2020.
