What researchers measure

Primary outcomes

  1. Number of Adverse Events Reported During the Study.

    Time frame: Thru the Month 24 Visit

  2. Change in C-peptide

    The Full Analysis Set (FAS) is the intent-to-treat (ITT) set of subjects. This set is defined as all T1DM subjects who were enrolled into the study and received implantation of at least one VC-01-250 or sentinel unit on Study Day 1. The FAS (Cohort 2 T1DM subjects who meet the FAS criteria) will be used to analyze the primary efficacy endpoint.

    Time frame: Baseline to the Month 6 Visit

Adverse events

Collected over AEs are recorded on the CRF from Visit 2 (Week-3) through the last subject visit (out to two years). At the conclusion of the trial, any ongoing AEs were followed up for 28 days after the explantation procedure.. Non-serious events are listed at a 5% frequency threshold.

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.
No changes since tracking began. The registry record was last updated on Mar 24, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
