Obstructive Sleep Apnea: what the trials found

Solriamfetol has demonstrated a significant improvement in cognitive performance as measured by the average of DSST RBANS scores (p=0.009) 1. Tirzepatide significantly reduced the Apnea-Hypopnea Index (AHI), with mean reductions reaching over 50% in some cohorts (p<0.001); notably, approximately 61% to 72% of participants achieved a reduction of at least 50% in AHI 15.

Armodafinil showed significant clinical improvement in the Clinical Global Impression of Change (CGI-C) (p=0.0120) and a significant reduction in scores on the Epworth Sleepiness Scale (ESS) (p=0.0027), despite no statistically significant change in the Maintenance of Wakefulness Test 13. JZP-110 was associated with reductions in ESS scores at various intervals, with some cohorts showing improvements of up to 7.9 points by week 12 18.

Xyrem demonstrated a statistically significant reduction in the mean Apnea-Hypopnea Index (AHI) compared to other treatment arms (p=0.009) 12. Other interventions, including Donepezil 5, Mometasone furoate nasal spray 14, and PMP-300E 22, did not show statistically significant improvements in AHI or related respiratory metrics.

Several other pharmacological agents were evaluated for the condition, including Venlafaxine 6, Guanfacine 7, Dexmedetomidine 11, and rozerem 21. Additionally, a combination of budesonide and montelukast did not significantly reduce the number of apnea or hypopnea events to less than 5 per hour (p=0.946) 20.

Recent results — preliminary, needs further review

  • Supplemental Oxygen is currently under investigation in Phase 1 trials 2.
  • Belun Ring Pulse Oximeter is being evaluated in a non-interventional study 3.
  • Hypoglossal Nerve Stimulation showed no significant difference in Pharyngeal Critical Pressure (p=0.80) or Pharyngeal Opening Pressure (p=0.94) 4.

For the clinician treating this condition

  • Tirzepatide is associated with a statistically significant and substantial reduction in Apnea-Hypopnea Index (AHI) 15.
  • Xyrem and Solriamfetol have shown statistically significant improvements in primary efficacy measures, specifically AHI and cognitive scores respectively [1, 12].
  • Armodafinil is associated with a significant reduction in Epworth Sleepiness Scale (ESS) scores 13.
