Summary

This study is an 8-week single center, randomized, double-blind, placebo-controlled, flexible titration trial evaluating the efficacy of solriamfetol in the treatment of fatigue symptoms in adult patients with chronic fatigue syndrome. Subjects will be randomized to a solriamfetol group or placebo group. The investigators will utilize an intent to treat model and impute data.

Criteria

Inclusion Criteria:

• All subjects must meet IOM 2015 diagnostic criteria for ME/CFS. These criteria will be assessed by obtaining clinical histories and using appropriate symptom checklists.

• All subjects must be 18-65 years of age at the time of consent.

• All sexually active males or females of child baring potential must agree to practice two different methods of birth control or remain abstinent during the course of the trial. Methods of birth control or contraception will be logged. Male and female contraception will be continued throughout the study and for 30 days after study discontinuation. Women of childbearing potential must test negative for pregnancy at the Screening Visit.

• All subjects must be able to swallow intact tablets.

• Subjects, in the opinion of the investigator, must be able to understand and comply with protocol requirements- including assessments, prescribed dosage regimens, and discontinuation of concomitant medications.

• All subjects must have a minimum level of intellectual functioning without evidence of significant general intellectual deficit, as determined by the primary investigator. Specific learning disorders will not be considered general intellectual deficits.

• All subjects must be able to provide written, personally signed and dated informed consent to participate in the study in accordance with the International Conference on Harmonisation (ICH) Good Clinical Practice (GCP) Guideline E6 and applicable regulations before completing any study related procedures.

• All subjects must be fluent in English and have a degree of understanding sufficient to communicate suitably with the primary investigator and the study coordinator.

• Subjects must have a negative drug screen for cocaine and other illicit (illegal for recreational use in the State of Michigan) drugs excluding cannabis due to legality of cannabis in Michigan. Subjects with a positive drug screen for confirmed prescription or over the counter use of medications will require the necessary washout per PI instruction. Subjects who test positive for any prohibited medications per PI maybe permitted with PI approval. Re-tests will not be allowed for a positive screen of an illicit drug.

• All subjects must score at or above a 4 on the CGIS-S at screening.

Exclusion Criteria:

• Subjects must not be immediate family of the Investigator or others directly affiliated with the study.

• Subjects must not have received treatment with a drug that has not received regulatory approval or participated in a clinical trial within 30 days prior to screening.

• Subjects must not have medical complications arising from being severely underweight or overweight.

• Subjects must not have a current co-morbid psychiatric disorder that is uncontrolled and associated with significant symptoms or that requires a prohibited medication or behavioral modification program. Co-morbid psychiatric diagnoses will be assessed during a psychiatric intake and scoring of the MINI.

• Subjects must not currently be considered a suicide risk (as determined by the primary investigator and assessed by the C-SSRS). They must not have made a suicide attempt within the past two years. They cannot have current suicidal ideation with intent or plan to act, or current suicidal behavior.

• Subjects must not have a history of substance abuse or drug dependence according to DSM-5 criteria currently or within one year prior to study participation, excluding nicotine and caffeine. This is determined through clinical history and symptom checklist to be obtained at visit 1.

• Subjects must not test positive for an illicit substance at the time of screening.

• Subjects must not have a serious chronic or acute unstable medical condition or illness, including cardiovascular, hepatic, respiratory, or hematologic illness, narrow angle glaucoma, or other unstable medical or psychiatric conditions that in the opinion of the Investigator would compromise participation or would likely lead to hospitalization during the duration of the study. Subjects with a history of intellectual impairment or a severe learning disability are also excluded.

• Subjects must not have a history of seizure disorder (other than infantile febrile seizures), any tic disorder, current diagnosis and/or family history of Tourette's disorder.

• Subjects must not have a history of organic heart disease including coronary artery disease, past myocardial infarction, angina, arrhythmias, congestive heart failure, valvular heart disease and congenital heart disease.

• Subjects must not be likely (as assessed by the primary investigator) to add psychotropic medications, apart from their current regimen or the drug under study, to their treatment regimen during the course of the study.

• Subjects must not have been previously enrolled in this study.

• Subjects must not anticipate relocation outside the geographic range of the investigative site during participation in the study. Subjects must not have extended travel plans inconsistent with the recommended visit intervals.

Subjects must not be taking any excluded medications that cannot be discontinued prior to beginning treatment with study medication. Subjects' medical history will be reviewed by the PI and current prescription regimen will be reviewed for CNS stimulants and noradrenergic and dopaminergic medications. The PI will determine on a case by case basis if concomitant use of the patient's current prescriptions would affect response to solriamfetol and reasoning for inclusion or exclusion will be documented. Stimulant medications will be excluded (methylphenidate or amphetamine based).

• Have a known hypersensitivity, allergy intolerance or documented history of non-responsivity to NDRIs or similar medication.

• Subjects who, in the opinion of the Investigator, are unsuitable in any other way to participate in the study.

• Subjects who have taken an MAOI within 14 of the beginning of the study.

• Subjects currently taking a medication regime that would otherwise likely interfere with the efficacy of solriamfetol or the integrity of study results as determined on a case by case basis by the primary investigator.
