Today's change
Crohn's Disease and Colitis led new recruitment this week
What moved across 103 tracked conditions, from the public trial registries. Changes compare against 26 July 2026.
Collected 2:00 am AEST, Monday 3 August 2026. This page is dated 2 August 2026 because that is the UTC date when the overnight sync ran; in Australia that sync lands in the early hours of the following morning, so the newest page always carries a date a day behind the Sydney calendar.
Two figures are withheld on this page. "Recruiting worldwide" and "Recruiting at Australian sites" were previously calculated by adding up per-condition totals, which counted a trial once for every condition it is listed under — overstating them by up to 17.8%. We hold no correct figure for this date and cannot reconstruct one, so we show nothing rather than a number we know is wrong. The condition-level boards below are unaffected: they were never built by adding across conditions. Current figures are on our statistics page.
Trials that changed phase this week
4 trials had their registered phase changed in the 7 days to 2 August 2026. Most phase changes are the registry correcting or reclassifying a record rather than a trial moving forward: none of them was a move to a later phase.
Hover or tap a change to see what it means.
What these changes mean
- Moved to a later phase
- The registry now lists the trial at a later phase than it did before. This is the case people usually picture, and it is the rarest of the four.
- Moved to an earlier phase
- The registry now lists the trial at an earlier phase. This is almost always a correction to how the study was described, not a trial going backwards.
- A phase was added
- The record previously listed no phase and now lists one. The study did not change; the registry entry did.
- A phase was removed
- The record previously listed a phase and now lists none. Again this is a change to the registry entry, not to the study.

Counted over the 7 days to 2 August 2026, over every trial we track, whether or not it is recruiting. A trial that finishes, is terminated or stops recruiting does not appear here — it is still a trial we track and still at the same phase, and its status change is what the boards below report. The figures above include 0 changes from and 2 changes to “no phase recorded”, which is why the four rows do not add up to them. Phase changes are rare. Over the 33 weekly windows to 12 August 2026 the registries changed the phase of between 0 and 6 trials a week, out of more than 200,000 we track, so a week with none is an ordinary week rather than a missing figure.
How these dates work. These changes are dated by when our nightly sync saw them, not by when the registry recorded them. We have since checked every one of them against ClinicalTrials.gov’s own version history: we saw them a median of six days late, and in one case twenty-nine. A change therefore falls in a later week here than the week it happened in — so a recent week can count changes that belong to an earlier one and read high, while the week they belong to reads low. A trial we have only just begun tracking has no earlier phase to compare against, so its first recorded phase is never counted as a change.

A quiet week doesn't reflect a condition's severity or research importance, only recent registry activity.
Our record of this begins on 1 July 2026, so a figure marked “+” means we have seen no increase for the whole time we have been recording — the true silence may be far longer. These numbers understate quietness; they cannot overstate it.

About these figures
Sourced from public government trial registries. Voxsanity is editorially independent and this page is not medical advice. Talk to your doctor about anything you read here.
This week's figures count registry changes, not our catch-up. We re-check only a portion of the trial registry each night, so a status that changed months or even years ago can reach our record this week. The board above no longer counts that: it counts trials whose status changed at ClinicalTrials.gov inside the window, dated by the registry's own record of when each change was published. The total number of recruiting trials we hold still moves for both reasons, which is why it is shown separately.
Percentages can mislead on small numbers. A condition with very few trials can show a large percentage change from a single new trial, which is why every row above leads with the absolute count and shows the percentage only as context.
