Disease research snapshot

No clinical trials have been linked to this exact normalized concept in the current published dataset. This is a coverage limitation, not evidence that the condition or medicine has never been studied. Try a synonym or browse registry-reported labels.

Numbers are derived from CureCurrent's current ClinicalTrials.gov projection and conservative MONDO/RxNorm mappings. See sources, counting rules and limitations and verify eligibility or clinical findings with the original study record.

Background context

Advanced sleep phase disorder

Advanced sleep phase disorder (ASPD), also known as the advanced sleep-phase type (ASPT) of circadian rhythm sleep disorder, is a condition that is characterized by a recurrent pattern of early evening (e.g. 7-9 PM) sleepiness and very early morning awakening (e.g. 2-4 AM). This sleep phase advancement can interfere with daily social and work schedules, and results in shortened sleep duration and excessive daytime sleepiness. The timing of sleep and melatonin levels are regulated by the body's central circadian clock, which is located in the suprachiasmatic nucleus in the hypothalamus.

How to interpret this record

CureCurrent links normalized diseases, medicines, registry study labels, sponsors and research sites. A link is not the same as a finding of clinical effectiveness. Our research guides explain how to compare studies, decode RxNorm identities, and avoid over-interpreting site and trial counts. See the published database coverage for mapping completeness.
