Melatonin Intervention For Neurocognitive Deficits in the St. Jude Lifetime Cohort

26 juni 2018 uppdaterad av: St. Jude Children's Research Hospital

Primary objective:

  1. To examine the efficacy of melatonin treatment on neurocognitive functioning in adult survivors of childhood cancer.

Secondary objectives:

  1. To evaluate the efficacy of melatonin treatment on delayed sleep onset latency in long-term childhood cancer survivors.
  2. 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.

Detaljerad beskrivning

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.

Vapen och interventioner

Deltagargrupp / Arm
Intervention / Behandling
Aktiv komparator: 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.
Andra namn:
  • N-Acetyl-5-Methoxytryptamine
Placebo-jämförare: 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.

Åtgärdsbeskrivning
Tidsram
Neurocognitive Function as Measured by Performance on Standardized Tests of Attention, Memory, and Executive Function.
Tidsram: 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.

Sleep Onset Latency as Measured by Actigraphy and Self-report.
Tidsram: Baseline and six months after start of therapy
Efficacy of melatonin on delayed sleep onset latency in long-term childhood cancer survivors (Cohorts 2 and 3 only). The measures were analyzed to compare change in sleep onset latency from baseline to 6 months between active treatment and placebo groups.
Baseline and six months after start of therapy
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.
Tidsram: 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.
