What is being measured

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

  1. Number of Participants With Varicella Glycoprotein Enzyme-Linked Immunosorbent Assay (gpELISA) Antibody Titer ≥ 5 gpELISA Units

    Antibody response to Varicella at 6 weeks postvaccination in participants with baseline titer <1.25 gpELISA units

    Measured: 6 weeks postvaccination

Secondary outcomes (8)
  1. Number of Participants With Postvaccination Measles Enzyme-Linked Immunosorbent Assay (ELISA) Antibody Titer ≥ 207.5 mIU/mL

    Antibody response to measles at 6 weeks postvaccination in participants initially seronegative (a titer <207.5 mIU/mL) to measles at baseline

    Measured: 6 weeks postvaccination

  2. Number of Participants With Postvaccination Mumps ELISA Antibody Titer ≥ 2.0 Ab Units/mL

    Antibody response to Mumps at 6 weeks postvaccination in participants initially seronegative (a titer < 2.0 Ab units/mL) to Mumps at baseline

    Measured: 6 weeks Postvaccination

  3. Number of Participants With Postvaccination Rubella ELISA Antibody Titer ≥ 10 IU/mL

    Antibody response to Rubella at 6 weeks postvaccination in participants initially seronegative (a titer <10 IU/mL) to Rubella at baseline

    Measured: 6 weeks Postvaccination

  4. Number of Participants With Serious Vaccine-Related Clinical Adverse Experiences (CAEs)

    Participants with a serious vaccine-related CAE (an AE which is assessed by an investigator/qualified physician as being related to study vaccine and results in death, persistent or significant disability/incapacity, prolongs an existing inpatient hospitalization, is life-threatening, a congenital anomaly/birth defect, a cancer, or an overdose).

    Measured: 6 weeks Postvaccination Visit 1 or Visit 2

  5. Antibody Response to Varicella at 6 Weeks Postvaccination in Participants With Baseline Titer < 1.25 gpELISA Units - Geometric Mean Titer (GMT)

    Postvaccination observed Geometric Mean Titer (GMT) of Varicella antibody. (Titers measured using Varicella zoster virus (VZV) gpELISA.)

    Measured: 6 weeks Postvaccination

  6. Antibody Response to Measles at 6 Weeks Postvaccination in Participants Initially Seronegative to Measles at Baseline - Geometric Mean Titer (GMT)

    Postvaccination observed Geometric Mean Titer (GMT) of Measles antibody. (Titers measured using Measles ELISA.)

    Measured: 6 weeks Postvaccination

  7. Antibody Response to Mumps at 6 Weeks Postvaccination in Participants Initially Seronegative to Mumps at Baseline - Geometric Mean Titer (GMT)

    Postvaccination observed Geometric Mean Titer (GMT) of Mumps antibody. (Titer measured using Mumps ELISA.)

    Measured: 6 weeks Postvaccination

  8. Antibody Response to Rubella at 6 Weeks Postvaccination in Participants Initially Seronegative to Rubella at Baseline - Geometric Mean Titer (GMT)

    Postvaccination observed Geometric Mean Titer (GMT) of Rubella antibody. (Titers measured using Rubella ELISA.)

    Measured: 6 weeks postvaccination

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Measles, Mumps, Rubella and Varicella (Oka-Merck) Virus Vaccine Live, Comparator: M-M-R II and Comparator: PUVV in people with Measles and Mumps, run by Merck Sharp & Dohme LLC.

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 2 inclusion and 6 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 10 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 15 Feb 2010). 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?

Number of Participants With Varicella Glycoprotein Enzyme-Linked Immunosorbent Assay (gpELISA) Antibody Titer ≥ 5 gpELISA Units (time frame: 6 weeks postvaccination). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00986232, which also lists 1 linked publication.

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 10 Apr 2015.
