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).
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.

Modafinil is used off-label based on supporting published evidence in major depressive disorder (antidepressant augmentation), multiple sclerosis-related fatigue, Parkinson disease-related excessive daytime sleepiness, and severe cancer-related fatigue (in patients receiving active treatment). Doses up to 400 mg/day, given as a singleMode dose, have been well tolerated, but there is no consistent evidence that this dose confers additional benefit beyond that of the 200 mg dose. Study drug administration will total 10 weeks.
The placebo will be tooled to look similar to the modafinil tablet, but it will not contain the active ingredient. Modafinil placebo dosing will follow the same titration scheme as modafinil treatment. Unblinded study personnel will manage modafinil and placebo disbursement to maintain blinding among participants and blinded study personnel, including site investigators.
The proposed doses and the schedule of dose escalation are consistent with currently approved FDA labeling for solriamfetol for other disorders of excessive daytime sleepiness. Solriamfetol dosing will total 10 weeks, including 3 weeks for titration and 7 weeks of maintenance. Solriamfetol will be given as a 75 mg tablet (1 or 2 per day) in the morning. The 3-week titration will be facilitated by phone calls between the study team and participants. Titrations in dose will be dependent upon participants' symptoms and tolerance to solriamfetol, with a goal of participants taking the highest dose permitted by symptoms. This dose will be used for the maintenance phase.
The placebo tablet will be tooled to look similar to the solriamfetol tablet, but it will not contain the active ingredient. Solriamfetol placebo dosing will follow the solriamfetol dosing scheme and goal. Unblinded study personnel will manage solriamfetol and placebo disbursement to maintain blinding among participants and blinded study personnel, including site investigators.

Change in total score of the PROMIS 8a SRI to assess sleep-related impairment
The PROMIS 8a SRI form includes a total of 8 items that ask participants to reflect on their sleep-related daytime impairment over the past 7 days with questions rated not at all to very much. T-Scores range from 0 to 100, with a score of 55 being 1 standard deviation above population mean. Higher scores indicate greater sleep-related impairment.
Time frame: Baseline, End of Intervention (Day 77)
Change in total score of the PROMIS 8b SD to assess sleep disturbance
The PROMIS 8b SD form includes a total of 8 items that ask participants to reflect on their sleep over the past 7 days with one question rated very poor to very good and the remaining questions rated not at all to very much. T-Scores range from 0 to 100, with \> 55 1 SD above population mean.
Time frame: Baseline, End of Intervention (Day 77)
Change in PROMIS 10a Fatigue score
The PROMIS 10a Fatigue is a 10-item questionnaire that assesses a participant's fatigue on a scale of 1 (not at all fatigued) to 5 (very much).
Time frame: Baseline, End of Intervention (Day 77)
Change in an objective neurocognitive battery score
Time frame: Baseline, End of Intervention (Day 77)
Change in ECog2 measure
Everyday Cognition 2 (ECog2) is a self-report, 41-item questionnaire used to measure measure the participant's perceived capacity to perform activities related to cognitive function, which could impact major activities of daily living and independence. It has been used for patients with mild cognitive impairment, Alzheimer's Disease, and dementia. It takes 5 minutes to complete.
Time frame: Baseline, End of Intervention (Day 77)
Change in PASC Symptom Questionnaire responses
Participants will be asked to complete a questionnaire that asks about the presence of PASC symptoms at Baseline and at follow-up visits. This questionnaire includes symptoms that have been associated with PASC.
Time frame: Baseline, End of Intervention (Day 77)
Change in total score on the Insomnia Severity Index (ISI)
The ISI is a 7-item, self-report questionnaire that assesses the nature, severity, and impact of insomnia, on a 5-point Likert scale (eg, 0 = not at all, 4 = extremely; scores: from 0 to 28). The ISI asks patients to recall their insomnia symptoms over the past 2 weeks.
Time frame: Baseline, End of Intervention (Day 77)
