What researchers measure

Primary outcomes

  1. Conversion rate from Type 3 transformation zone (TZ) to Types 1 or 2

    The rate of participants with successful transformation from Type 3 (TZ) to Type 1 or 2 (TZ) will be calculated. It is the number of participants who successfully transformed from Type 3 TZ to Type 1 or 2 TZ, divided by the total number of participants in the entire randomized cohort.

    Time frame: Approximately 2-3 hours and approximately 4-6 hours since drug administration

Secondary outcomes

  1. Comparison of the rate of patients converted from Type 3 TZ to Type 1 or 2 TZ between 2-3 hours and 4-6 hours

    The rate of transformation from Type 3 transformation zone (TZ) to Type 1 or 2 TZ between 2-3 hours and 4-6 hours after administering misoprostol will be compared. The rate is calculated as the number of successful transformations within each time period (2-3 hours or 4-6 hours) divided by the total cohort.

    Time frame: Approximately 2-3 hours vs approximately 4-6 hours

References and documents

Individual participant data

Plan to share: No — Individual participant data (IPD) will not be shared publicly because the study collects sensitive personal and health information from participants, and broad data sharing could compromise participant privacy and confidentiality despite de-identification efforts. In addition, the informed consent process and ethics approvals did not include provisions for unrestricted public sharing of individual-level data. Access to study data will therefore remain restricted to the study investigators and authorized personnel for approved research purposes, in accordance with institutional policies, ethical approvals, and applicable data protection requirements.

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Feb 2025 (actual). Primary completion is estimated for Nov 2027, 32 months after the start.

Of 445 non-industry interventional studies with no phase under Uterine Cervical Neoplasms, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 71. This study's planned 32 months is close to that.

Counting every sponsor, half of 461 studies reached it within 33 months; a quarter within 15 and three quarters within 71.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
