Sunosi™

(solriamfetol)

Tablet

Improve wakefulness in adult patients with excessive daytime sleepiness associated with narcolepsy or obstructive sleep apnea (OSA)

Limitations of Use:

Not indicated to treat the underlying airway obstruction in OSA. Ensure that the underlying airway obstruction is treated (e.g., with continuous positive airway pressure [CPAP]) for at least one month prior to initiating Sunosi for excessive daytime sleepiness. Modalities to treat the underlying airway obstruction should be continued during treatment with Sunosi. Sunosi is not a substitute for these modalities.

CLINICAL RATIONALE

Clinical Rationale

Excessive daytime sleepiness (EDS) is characterized by persistent sleepiness regardless of how much sleep an individual gets at night. In between sleep attacks, individuals have normal levels of alertness, particularly if doing activities that keep their attention.(2) The most common causes of EDS include narcolepsy, obstructive sleep apnea, shift work disorder, sleep deprivation, medication effects, and other medical and psychiatric conditions.(5)

Narcolepsy

Narcolepsy is a chronic neurological disorder caused by the inability to regulate sleep-wake cycles. At various times throughout the day, patients with narcolepsy experience irresistible bouts of sleep and could fall asleep. If left undiagnosed or untreated, narcolepsy can interfere with psychological, social, and cognitive function and development and can inhibit academic, work, and social activities. Symptoms may include excessive daytime sleepiness, cataplexy, sleep paralysis, and hallucinations. All patients diagnosed with narcolepsy will have excessive daytime sleepiness. However, sleepiness in narcolepsy is more like a “sleep attack”, where an overwhelming sense of sleepiness comes on quickly.(2) There is limited evidence to advise on treatment of special populations such as children, pregnant women, and breastfeeding mothers.(4)

The American Family Physician recommends referral to a sleep clinic if narcolepsy is suspected.(3) The American Academy of Sleep Medicine indicates treatment goals should be to alleviate daytime sleepiness and produce the fullest possible return of normal function for patients at work, school, home, and socially.(4)

The American Academy of Sleep Medicine (AASM) 2021 guidelines combined the recommendations for narcolepsy with cataplexy and EDS associated with narcolepsy. The AASM recommend the following for the pharmacologic treatment with narcolepsy:(8)

  • Strong treatment recommendations:
    • Modafinil
    • Pitolisant
    • Sodium oxybate
    • Solriamfetol
  • Conditional treatment recommendations:
    • Armodafinil
    • Dextroamphetamine
    • Methylphenidate
  • There was insufficient evidence to make recommendations for SSRI and SNRIs for the treatment of narcolepsy.

Efficacy(1)

The efficacy of Sunosi in improving wakefulness and reducing excessive daytime sleepiness was demonstrated in a 12-week, multi-center, randomized, double-blind, placebo controlled, parallel-group study (Study 1; NCT02348593) in adult patients with a diagnosis of narcolepsy according to the ICSD-3 or DSM-5 criteria.

Wakefulness and sleepiness were assessed using the Maintenance of Wakefulness Test(MWT) and the Epworth Sleepiness Scale (ESS). Compared to the placebo group, patients randomized to 150 mg Sunosi showed statistically significant improvements on the MWT and on the ESS at Week 12.

Obstructive Sleep Apnea (OSA)

Obstructive sleep apnea (OSA) is a prevalent condition with serious health consequences, including EDS, cognitive disturbances, depression, hypertension, and cardiovascular and cerebrovascular disease.(7)

Guidelines from the American College of Physicians (ACP) on management of OSA do not include modafinil/armodafinil in their recommendations for treatment. ACP guidelines state that pharmacologic therapy is not currently supported by evidence and should not be prescribed for OSA treatment.(7) The American Academy of Sleep Medicine (AASM) practice parameters recommend modafinil in patients with OSA for the treatment of residual excessive daytime sleepiness despite effective positive airway pressure treatment and who are lacking any other identifiable cause for their sleepiness.(7)  Both guidelines recommend weight loss for obese and overweight patients and continuous positive airway pressure treatment as initial therapy.(6,7)

A review on the treatment of OSA suggested pharmacologic agents play a minimal role in the treatment of breathing itself in patients with a sleep disorder. Modafinil and armodafinil are considered adjunctive therapies to improve wakefulness in these patients. These agents are recommended for patients who experience residual sleepiness despite optimal CPAP therapy, provided CPAP compliance is closely monitored. Modafinil or armodafinil do not treat the OSA itself but only the associated symptoms of sleepiness. The majority of patients (75%) with severe sleepiness at baseline still had mean multiple sleep latency times of less than 10 minutes despite the addition of modafinil to effective therapy with CPAP. This suggests that these drugs do not necessarily eliminate the risk of motor vehicle and other accidents in the OSA population. Concern also exists that the use of pharmacotherapy to treat excessive sleepiness associated with OSA may lead to subsequent reduction in CPAP compliance.(6)

Efficacy (1)

The efficacy of Sunosi in improving wakefulness and reducing excessive daytime sleepiness in patients with OSA was demonstrated in a 12-week multi-center, randomized, double-blind, placebo-controlled study (Study 2; NCT02348606) in adults diagnosed with OSA according to ICSD 3 criteria. 
Compared to the placebo group, patients randomized to 37.5 mg, 75 mg, and 150 mg Sunosi showed statistically significant improvements on the MWT and ESS. At Week 12, 37.5 mg, 75 mg, and 150 mg of Sunosi all demonstrated improvements in wakefulness compared to placebo as assessed in test sessions 1 (approximately 1 hour post-dose) through 5 (approximately 9 hours post-dose) of the MWT. 

Safety(1)

Sunosi is contraindicated in patients receiving concomitant treatment with monoamine oxidase inhibitors (MAOI), or within 14 days following discontinuation of MOAI, due to the risk of hypertensive reactions.
