How this study is set up

The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

  • Present: Registered before enrolment beganFirst posted 2024-11-18; recorded start 2024-11-26
  • Present: Has a defined primary outcomeA primary outcome measure is listed in the record
  • Present: The primary outcome states a time frameThe primary outcome measure records a time frame
  • Present: Participants are randomly assignedAllocation is recorded as randomised
  • Present: Has a comparison groupThe record lists a placebo or comparator arm, or more than one study arm
  • Present: Uses blinding (masking)A masking level is recorded in the record
  • Not stated: An ethics committee is not stated in the registry recordThis registry's ingested record has no ethics-committee field
  • Not stated: Regulatory oversight (such as an IND or IDE) is not stated in the registry recordThis registry's ingested record has no regulatory-authorisation field
  • Not stated: A data monitoring committee is not stated in the registry recordThis registry's ingested record has no data-monitoring-committee fieldA data monitoring committee is not required for many smaller studies, and its absence here is not unusual.
  • Present: No cost to participants is mentioned in the recordChecked the summary, description and eligibility text; no cost-to-participant phrase found
  • Present: Sponsor has 321 other studies in this databaseCounted from the lead sponsor named in the record (GlaxoSmithKline)
  • Present: Sponsor has posted results for at least one studyBased on the sponsor’s studies in this database
  • The record lists 1 condition.
  • Lead sponsor type recorded as: industry.
  • Intervention regulatory context: investigational, within a phased regulatory pathway.

Trial stature

Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

Methodological rigourDEFINITIVE

A definitive-grade design for a phase 3 study, judged from its ClinicalTrials.gov record.

How this score is built
  • Randomised allocation20/20

Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

How this score is built
  • Investigator standing0/100

    No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

תקציר

The purpose of this study is to assess how well-tolerated GSK's investigational varicella vaccine (VNS Vaccine) is, in comparison to an already approved varicella vaccine (VV) known as Varivax. The study will be conducted on healthy children aged 12 to 15 months, and who have neither contracted varicella nor received a varicella vaccination.
