RECOVER-SLEEP: Platform Protocol, Appendix_A (Hypersomnia)

Summary

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

DRUG

Modafinil

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.

DRUG

Modafinil Placebo

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.

DRUG

Solriamfetol

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.

DRUG

Solriamfetol Placebo

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.
