In a latest research printed within the New England Journal of Drugs, researchers investigated the consequences of tirzepatide on adults with weight problems and moderate-to-severe obstructive sleep apnea (OSA).
They discovered that tirzepatide considerably lowered the apnea-hypopnea index (AHI), physique weight, focus of high-sensitivity C-reactive protein (hsCRP), hypoxic burden, and systolic blood stress (SBP), and improved patient-reported sleep-related outcomes in comparison with placebo.

Background
OSA is marked by repetitive pharyngeal collapse throughout sleep, resulting in apneas, hypopneas, hypoxemia, hypercapnia, and arousal, with vital signs like extreme daytime sleepiness and an elevated cardiovascular threat. Affecting over 900 million folks globally, with 40% experiencing moderate-to-severe OSA, the situation has substantial medical and financial impacts.
Conventional remedies for the situation concentrate on mechanical help, primarily optimistic airway stress (PAP) remedy, which improves the AHI however has restricted adherence and no confirmed discount in cardiovascular outcomes.
Various remedies like mandibular development and upper-airway surgical procedure are both much less efficient or invasive. Additional, OSA has no authorised prescription drugs.
Extra adiposity is a key reversible threat issue, making weight administration essential. Tirzepatide, a long-acting GIP (quick for glucose-dependent insulinotropic polypeptide) and GLP-1 (quick for glucagon-like peptide-1) receptor agonist, has proven a big lower in physique weight, blood stress, and irritation, suggesting that it might be efficient for OSA by addressing weight problems and its associated issues.
Within the current research, researchers current the outcomes of two SURMOUNT-OSA part III trials, which investigated the protection and efficacy of tirzepatide in treating adults with OSA and weight problems.
In regards to the research
The SURMOUNT-OSA trials consisted of two part III, double-blinded, randomized managed research performed between June 2022 and March 2024 throughout 60 websites in 9 international locations, aimed toward evaluating the protection and efficacy of tirzepatide in adults with moderate-to-severe OSA (AHI ≥15 occasions per hour) and weight problems (BMI ≥30 or ≥27 in Japan).
Trial 1 included contributors not ready or not keen to make use of PAP remedy, whereas trial two concerned contributors utilizing PAP remedy for a minimum of three months. Members with kind 1 or 2 diabetes, latest vital weight change, deliberate surgical procedure for sleep apnea or weight problems, main craniofacial abnormalities, and central or blended sleep apnea have been excluded.
In trials 1 and a pair of, the contributors had a imply age of 47.9 and 51.7 years, respectively. A majority of the contributors have been male (67.1%, 72.3%) and White (65.8%, 73.1%).
After screening for 4 weeks, contributors have been assigned to trial 1 (n = 234) or trial 2 (n = 235) and randomly given tirzepatide or placebo as soon as weekly for 52 weeks.
The first endpoint was the alteration in AHI from baseline. Secondary endpoints included p.c change in AHI, discount in AHI by a minimum of 50%, attaining AHI of > 5 occasions per hour, change in physique weight, hsCRP focus, hypoxic burden, PROMIS (quick for patient-reported outcomes measurement data system) scores for sleep disturbance (PROMIS-SD) and sleep-related impairment (SRI), and SBP.
Opposed and severe antagonistic occasions have been monitored all through the reporting interval. Statistical evaluation concerned treatment-regimen and efficacy estimands, evaluation of covariance, logistic regression, and a number of imputations for lacking knowledge.
Outcomes and dialogue
The trials confirmed a excessive completion fee (82.9%) and excessive total adherence (79.7%). Estimand evaluation confirmed that tirzepatide therapy considerably lowered the AHI as in comparison with the placebo in each trials (p<0.001).
Moreover, contributors on tirzepatide confirmed enhancements in sleep apnea-specific hypoxic burden, and greater than 50% achieved clinically significant reductions in AHI.
Additional, contributors who acquired tirzepatide in each trials 1 and a pair of skilled vital reductions in PROMIS-SRI and PROMIS-SD T scores in addition to physique weight, systolic blood stress, and hsCRP focus.
No deaths have been reported throughout the trials. Nonetheless, contributors receiving tirzepatide reported increased charges of gastrointestinal antagonistic occasions, with two instances of acute pancreatitis in trial 2.
The trials are strengthened by their world nature, enough dimension, vital illustration of girls, evaluation of a number of related endpoints, and generalizability, and offered insights into tirzepatide’s results in sufferers with and with out present PAP remedy.
Nonetheless, the restrictions of the trials embody their quick length, exclusion of non-obese contributors, lack of research on PAP adherence, unexamined symptom presence at baseline, undefined medical significance for PROMIS measures, and evaluation solely as much as 52 weeks of therapy.
Conclusion
In conclusion, within the two trials, tirzepatide was discovered to deliver a few clinically vital enchancment in sleep-disordered respiration, sleep disturbance, and sleep-related impairment whereas decreasing OSA-related cardiovascular threat elements, together with AHI, physique weight, hypoxic burden, hsCRP focus, and SBP in people with moderate-to-severe OSA and weight problems.
These outcomes spotlight tirzepatide’s potential as a therapy possibility for enhancing sleep-related outcomes on this inhabitants.
