Study summary

This study of a randomized controlled trial aims to evaluate the feasibility of a 12-week sleep program and the randomized controlled trial research procedure. In total 20 participants will be recruited and randomized to the intervention or control group.

Read the detailed description

This feasibility study of a randomized controlled trial, aims to evaluate the feasibility of a 12-week sleep program consisting on aerobic exercise and cognitive-behavioral therapy. In this study the investigators wish to evaluate the program as well as the randomized controlled trial research procedure.

In total 20 participants will be recruited and randomized to either the intervention group (n=10) or control group (n=10).The intervention group will participate in two exercise sessions each week and four sessions based on cognitive-behavioral therapy for insomnia.

Timeline

Tracking 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

Ran from Mar 2018 to primary completion in Mar 2019, 12 months.

Of 1,098 non-industry interventional studies with no phase under Prostatic Neoplasms, half reached primary completion within 43 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 87. This study's 12 months is below that.

Counting every sponsor, half of 1,155 studies reached it within 43 months; a quarter within 22 and three quarters within 86.

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.
No changes since tracking began. The registry record was last updated on May 5, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
