RECOVER-SLEEP: Platform Protocol, Appendix_B (CPSD)

June 1, 2026 updated by: Duke University

RECOVER-SLEEP: A Platform Protocol for Evaluation of Interventions for Sleep Disturbances in Post-Acute Sequelae of SARS-CoV-2 Infection (PASC)

The platform protocol is designed to be flexible so that it is suitable for a range of study settings and intervention types. Therefore, the platform protocol provides a general protocol structure that can be shared by multiple interventions and allows comparative analysis across the interventions. For example, objectives, measures, and endpoints are generalized in the platform protocol, but intervention-specific features are detailed in separate appendices.

This platform protocol is a prospective, multi-center, multi-arm, randomized controlled platform trial evaluating potential interventions for PASC-mediated sleep disturbances. The hypothesis is that symptoms of sleep and circadian disorders that emerge in patients with PASC can be improved by phenotype-targeted interventions. Specific sleep and circadian disorders addressed in this protocol include sleep-related daytime impairment (referred to as hypersomnia) and complex PASC-related sleep disturbance (reflecting symptoms of insomnia and sleep-wake rhythm disturbance).

Study Overview

Detailed Description

Interventions will be added to the platform protocol as appendices. Each appendix will leverage all elements of the platform protocol, with additional elements described in the individual appendix.

After completing Baseline assessments, participants will be randomized to an intervention group, which is based on their sleep phenotype, or into a placebo/control group.

  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Active TL + Oral Melatonin
The Complex PASC-Related Sleep Disturbances (CPSD) Appendix B combines brief education and a tailored sleep timing prescription for CPSD (referred to as RESET-PASC) with therapies that modify circadian timing for participants who report poor sleep quality. The intervention therapies involve tailored lighting (TL) and melatonin. Participants will be randomly assigned to one of four groups: (a) active TL + oral melatonin, (b) active TL + placebo melatonin, (c) placebo TL + oral melatonin, and (d) placebo TL + placebo melatonin. All groups will receive RESET-PASC. The intervention duration will be 8 weeks.
Melatonin dosing will be one tablet of 3 mg immediate release daily consumed 2 hours before the participant's desired bedtime, which is defined as the time at which the participant tries to fall asleep.
TL will be delivered similarly to both active and placebo groups, but the circadian stimulus (the amount of light) will be different, albeit practically unidentifiable to participants.

Melatonin placebo dosing will be one placebo tablet once daily consumed 2 hours before the participant's desired bedtime.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in sleep onset variability, assessed using a wearable device
Time Frame: Baseline, End of Intervention (Day 63)
A wearable device will be used as an objective measure to assess sleep onset variability assessed for 7 days before randomization and 7 days before EOI
Baseline, End of Intervention (Day 63)
Change in total score of the PROMIS 8b SD to assess sleep disturbance
Time Frame: Baseline, End of Intervention (Day 63)
