Melatonin Intervention For Neurocognitive Deficits in the St. Jude Lifetime Cohort
Primary objective:
- To examine the efficacy of melatonin treatment on neurocognitive functioning in adult survivors of childhood cancer.
Secondary objectives:
- To evaluate the efficacy of melatonin treatment on delayed sleep onset latency in long-term childhood cancer survivors.
- To investigate whether improvement in sleep onset latency due to melatonin treatment is associated with neurocognitive improvement in long-term childhood cancer survivors.
This study is a randomized double-blind placebo controlled trial of time release melatonin for adult survivors of childhood cancer who demonstrate impaired neurocognitive functioning and/or difficulty falling asleep.

Részletes leírás
All participants undergo a general neurocognitive evaluation at baseline and 6-month follow-up, focused on assessment of intelligence, academic skills, attention, processing speed, memory and executive functions.
Sleep parameters using self-report and actigraphy will be assessed at three time points during the study: Baseline, 3-months, and 6-months.
Participants will be divided into 3 mutually exclusive groups:
- Cohort 1: Participant has neurocognitive impairment defined as performance on at least one measure of attention, memory, and/or executive functioning at or below the 10th percentile, AND is absent of delayed sleep onset latency defined as an inability to fall asleep within 30 minutes less than once a week during the past month.
- Cohort 2: Participant has neurocognitive impairment defined as performance on at least one measure of attention, memory, and/or executive functioning at or below the 10th percentile, AND has delayed sleep onset latency defined as self-report of an inability to fall asleep within 30 minutes at least once a week during the past month.
- Cohort 3: Participant is absent of neurocognitive impairment defined as performance >10th percentile on all six measures of attention, memory, and executive functioning, AND has delayed sleep onset latency defined as self-report of an inability to fall asleep within 30 minutes > once a week during the past month.
Within each group, participants will be randomly assigned to take either 3 mgs of time release melatonin or placebo 1-2 hours before bedtime each night for 6 months.
Psychosocial measures of health-related quality of life and psychological distress will be completed at baseline and following 6 months of melatonin/placebo treatment.
Biological samples for serum melatonin levels will be collected at baseline and at the 6 month follow-up evaluation.

Aktív összehasonlító: Melatonin
Participants receive 3 mgs of time-release melatonin 1-2 hours prior to bedtime.
|
Melatonin 3mg time release will be given.
Participants will be instructed to take one 3mg time released tablet by mouth approximately 1-2 hours before initiating sleep onset, preferably at the same time each night.

Placebo Comparator: Placebo
Participants receive a placebo identical to the time-release melatonin and are instructed to take it 1-2 hours prior to bedtime.
|
Placebo tablets to match the melatonin will be comprised of inert substances.

Neurocognitive Function as Measured by Performance on Standardized Tests of Attention, Memory, and Executive Function.
Időkeret: Baseline and 6 months after start of therapy
|
Efficacy of melatonin treatment on neurocognitive functioning in adult survivors of childhood cancer (Cohorts 1 and 2 only).
The measures were analyzed to compare change in neurocognitive performance from baseline to 6 months between active treatment and placebo groups.
The unit of measure is a standardized z-score with a mean of 0 and standard deviation of 1.
A higher z-score represents a better outcome.

Neurocognitive Function as Measured by Performance on Standardized Tests of Attention, Memory, and Executive Function, and Sleep Onset Latency as Measured by Actigraphy and Self-report.
Időkeret: Baseline and six months after start of therapy
|
Investigate whether improvement in sleep onset latency due to melatonin treatment is associated with neurocognitive improvement in long-term childhood cancer survivors (Cohort 2).
The change in neurocognitive performance from baseline to 6 months will be examined in relation to change in sleep onset latency.
The unit of measure is a standardized z-score with a mean of 0 and standard deviation of 1.
The unit of measurement is a correlation coefficient (Pearson's R2).
The range is from -1.0 to 1.0.
A zero indicates no correlation while values closer to -1.0 or 1.0 reflect a stronger association.
A negative correlation suggests that as sleep latency decreased, neurocognitive functioning improved.
