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.

Following criteria:

Pan American 网红黑料 Organization:

Suspected case of SARS-CoV-2 infection Three options, A through C:

A. Met the clinical OR epidemiological criteria:

1. Clinical criteria: Acute onset of fever AND cough (influenza-like illness) OR

cough, general, weakness/fatigue, headache, myalgia, sore throat, coryza,

dyspnea, nausea, diarrhea, anorexia;

1. Epidemiological criteria: Contact of a probable or confirmed case or linked to a COVID-19 cluster; or B. Presented with acute respiratory infection with a history of fever or measured fever of 鈮� 38掳C and cough, with onset within the last 10 days, and required hospitalization; or C. Presented with no clinical signs or symptoms, NOR meeting epidemiologic criteria with a positive professional use or self-test SARS-CoV-2 Antigen-Rapid Diagnostic Test.

Probable* case of SARS-CoV-2 infection, defined as having met the clinical criteria

above AND was a contact of a probable or confirmed case or is linked to a COVID-19

cluster; or

Confirmed case of SARS-CoV-2 infection * Two options, A through B:

A. Presented with a positive nucleic acid amplification test, regardless of clinical

criteria OR epidemiological criteria; or B. Met clinical criteria AND/OR

epidemiological criteria (See suspected case A), with a positive professional use or

self-test SARS-CoV-2 Antigen-Rapid Diagnostic Test.

• Suspected and probable cases will only be allowed if they occurred before May 1, 2021, and will be limited to 10% of the study population. Otherwise, confirmed cases are required.

1. New/worse sleep problems following a SARS-CoV-2 infection that have persisted for at least 12 weeks and are still present at the time of consent

2. PROMIS 8a SRI or 8b SD T Score 鈮� 55 Screening with both the PROMIS 8a SRI and 8b SD will occur for the phenotype assessment portion of the protocol.

3. Willing and able to provide informed consent, complete the surveys and clinical assessments, and return for all of the necessary follow-up visits

4. Adequate method of birth control for participants of child-bearing potential

Exclusion Criteria:

An individual who meets any of the following criteria will be excluded from participation

In this study:

1. Known active acute SARS-CoV-2 infection 鈮� 4 weeks from consent

2. Known pregnancy, breastfeeding, or contemplating pregnancy during the study period

3. Untreated sleep apnea (AHI 鈮� 15 or severe sleep-related hypoxemia)

4. Current night or rotating shift work

5. Known history of narcolepsy prior to SARS-CoV-2 infection

6. Any non-marijuana illicit drug use within 30 days of informed consent

7. Known history of severe mental disorder, such as psychotic disorders and bipolar disorder

8. Current or recent use (within the last 14 days) of study intervention or similar intervention to treat the underlying condition, unless a washout period is permitted per appendix*

9. Known allergy/sensitivity or any hypersensitivity to components of the study intervention or control*

10. Known contraindication(s) to study intervention including prohibited concomitant

medications and without the ability to safely hold prohibited concomitant

medications (see appendices)*

1. Currently receiving/using intervention from another clinical trial that could impact

or mask treatment effect; refer to MOP for details

1. Any condition that would make the participant, in the opinion of the investigator,

unsuitable for the study

(*)If only one study intervention appendix is open at the time of enrollment. If multiple

study intervention appendices are open, a participant may be excluded from any study

intervention appendix based on contraindications listed in the study intervention

appendix, current use of study intervention, or known

allergy/sensitivity/hypersensitivity yet remain eligible for the remaining study

intervention appendices.
