VENICE, ITALY — Personalized doses and slack tapering of semaglutide (Wegovy or Ozempic, Novo Nordisk) in sufferers who moreover practice a digital weight reduction program can consequence in maintenance of target weight as a lot as 6 months later, declare retrospective, real-world knowledge.
Lower doses had been found to be upright as efficient as greater doses for weight reduction. Slowly reducing medicine while specializing in method of life changes the utilize of a digital program looked as if it would reduction quit weight come by, said the look lead Henrik Gudbergsen, MD, lead researcher and chief clinical officer at Embla, a digital weight reduction health heart, in Copenhagen, Denmark.
Sufferers within the weight reduction program feeble spherical a third (36.1%) of the instant cumulative semaglutide dose and lost a median of 14.8% (95% CI, 14.3%-15.2%) of body weight by week 64. Sideeffects incorporated nausea, vomiting, and stomachache, nonetheless had been soft and transient.
“It be the same amount of weight reduction considered within the phase 3 trials [of semaglutide], so contributors moreover lose roughly 15% of the weight they’ve when they join our program nonetheless with a third of the medication. The strategy in which of life changes in point of fact work,” Gudbergsen told Medscape Scientific Files.
Of these sufferers who tapered off semaglutide to zero — knowledge are available in for 85 members — a stable body weight became maintained for the first 26 weeks.
The work is being offered as two posters on 13 and 14 Could at the European Congress on Obesity (ECO) 2024.
“Our results declare that weight reduction is achievable no matter initial body mass index (BMI) and the amount of semaglutide feeble,” said Gudbergsen. “The usage of decrease doses of semaglutide is more cost effective for sufferers, finally ends up in fewer facet results, and helps build obvious stocks of the drug, that are detached minute, stir further.”
Reflecting on the persisted minute weight reduction after stopping, Gudbergsen said, “The combination of beef up in making method of life changes and slack tapering appears to be like to permit sufferers to serve some distance from regaining weight after coming off semaglutide. I believe that is testomony to the indisputable truth that they in point of fact enjoy discovered extra about emotional drinking behaviors, method of life, meals, exercise, and plenty others, and never upright relied on semaglutide for the weight reduction. They’re in point of fact as a lot as tempo.”
Gudbergsen moreover notorious that the decrease most dose facilitated engagement with supportive method of life changes all around the program that “ought to reduction with shedding weight and with conserving it off.”
Weight Loss With out Aspect Results
Gudbergsen and his colleagues at Embla wished to discover if semaglutide will most certainly be tailored to carry out weight reduction with minimal facet results, as neatly as figuring out, whether or not once the target weight became done, the drug dose will most certainly be slowly tapered to zero with out weight come by.
A total of 2246 contributors residing with weight problems (BMI ≥ 30) or overweight with at the least one weight-connected comorbidity (BMI between 27 and 29.9) had been incorporated within the look. All members lived in Denmark, and the median age became 49 years (41-55 years), and the median BMI became 33.2. They had been all enrolled within the Embla digital weight reduction app program.
As a weight reduction program, Embla comprises a combination of weight reduction medicine and method of life changes supported by nurses, clinical doctors, health coaches, and a psychologist, while Embla communities beef up every utterly different.
Contributors received a tailored version of the long-established semaglutide dosing time desk (starting at 0.25 mg once weekly, with 4-weekly incremental increases to 2 mg most for Ozempic and 2.4 mg for Wegovy) to ascertain the lowest efficient dose that accommodated any facet results. Doses had been increased if weight reduction stagnated, nonetheless if a weekly weight lack of at the least 0.5% of body weight became done, then the dose remained the same. The tapering idea involved slowly reducing the medications over a median of 9 weeks.
Weight Loss Maintained After Stopping Semaglutide — Slight Numbers
After 26, 64, and 76 weeks, a entire of 1,392, 359, and 185 members remained within the program, respectively (median total practice-up time became 32 weeks for the 2246 contributors who started the program).
The common most dose of semaglutide became 0.77 mg, and all members with a reported weight at week 64 lost over 5% of their body weight, and 85.3% lost over 10% of their baseline body weight. There became no difference within the amount of weight reduction done in step with baseline BMI and/or cumulative dose of semaglutide.
Within the 353 members who tapered their semaglutide dose, the median length of the tapering became 9 weeks (95% CI, 8%-10%), after which time the median change in body weight became −2.1% (95% CI, −3.5% to −0.8%). Virtually 40% began tapering after 72 weeks on the program.
A total of 240 sufferers (of 353) stopped the drug utterly, and available knowledge from 85 of these members showed an common body weight lack of −1.5% (95% CI, −6.4% to three.3%) at 26 weeks after stopping. The median practice-up time after stopping became 19.5 weeks.
“On myth of they’ve engaged in about a of the method of life changes, when they within the raze taper off, they serve the weight off with out semaglutide,” said Gudbergsen. “I believe there is a sturdy linkage between the initial phase of the utilize of this medicine with method of life changes and with out a doubt being able to conserving the kilos off after they’ve stopped.”
Of the 46 members who restarted semaglutide, body weight had increased since stopping by 1.3% (95% CI, −0.1% to 2.7%), and the probability of restarting became 21.5% (95% CI, 14.8-27.6%) 26 weeks after stopping semaglutide.
Asked to comment on the work, Esben Selmer Buhl, MD, PhD, fundamental practitioner physician, Institute for Effectively being and Society, College of Oslo, Oslo, Norway, said, “We all know from utterly different experiences that after a most fundamental weight reduction — no matter the regimen feeble — the weight adjusted metabolic rate is decreased by approximately 25%, and the patient’s potential to of direction feel satiety is vastly impaired while the feeling of hunger is vastly upregulated,” he explained, adding that, “Study moreover counsel this location persists for years in these completely about a who are in a job to withhold their weight for a in point of fact long time after a most fundamental weight reduction.”
Having to address a decreased basal metabolic rate as neatly as to being hungrier than ever explains why sustained weight reduction is sophisticated over time. “I am skeptical that basically fizzling out semaglutide will essentially change these cases. I have faith about the wide majority of sufferers in Embla’s look would commence to come by weight at some level, after being left on their very enjoy, and this corresponds to my clinical expertise.”
“We enjoy tried reducing and even in point of fact fizzling out semaglutide, nonetheless at some level — on the entire within 3-18 months — all sufferers will commence regaining weight, and now we enjoy found that our sufferers need repeated therapy cycles to withhold body weight. Many sufferers desire eternal sematglutide therapy to precise weight maintenance to sever the risk of yo-yo weight cycling.”
“Nonetheless, not least because of the costs for semaglutide, decrease-dose semaglutide, for event, 1.0 mg per week as neatly as to diet and exercise, appears to be like to be a candy set for declaring the weight lost,” said Selmer Buhl.
