A well-liked prescription drug that’s used to deal with kind 2 diabetes or to handle weight in adults appears to be each protected and efficient for weight reduction in kids – no less than within the brief time period, in line with new outcomes.
Liraglutide (model title Victoza or Saxenda) belongs to the identical class of medication as semaglutide, which is the drug behind Ozempic and Wegovy.
The subcutaneous injection was first authorised within the US as an adjunct remedy for kind 2 diabetes in 2010. 4 years later, it was authorised for weight administration in adults who’re thought of obese or overweight.
Regardless of its surging recognition, the long-term results of liraglutide and comparable medicine are nonetheless being investigated, even amongst adults. Their use amongst kids stays controversial.
Whereas some scientists have warned that liraglutide could also be harmful or have unintended penalties for teenagers in the long term, in 2019, the US Meals and Drug Administration authorised liraglutide to be used in sufferers with kind 2 diabetes who’re 10 years or older.
Thus far, no drugs are at present authorised for the remedy of weight problems in kids youthful than 12.
A section 3 scientific trial amongst 82 members has now supplied preliminary outcomes that liraglutide, mixed with different way of life interventions, is each protected and efficient as a weight reduction drug for kids as younger as six years previous.
Roughly a 12 months after beginning the trial, which was funded by liraglutide maker Novo Nordisk, members between the ages of 6 and 12 who got the liraglutide decreased their physique mass index by 5.8 p.c. These given a placebo over the identical interval confirmed elevated BMIs by about 1.6 p.c.
Youngsters at this age are nonetheless rising, so it’s anticipated that some weight achieve would happen with out drug remedy over the course of a 12 months.
All taking part kids had been endorsed by certified well being care professionals and inspired to eat healthily and train for an hour or so a day.
“In our examine, diastolic blood strain and… a measure of blood sugar management improved extra in kids receiving liraglutide than in these receiving the placebo,” explains lead researcher and pediatrician Claudia Fox from the College of Minnesota Twin Cities. Fox has acquired grant and get in touch with assist from Novo Nordisk and one other pharmaceutical firm, Eli Lilly.
The prevalence of detrimental unintended effects was about the identical amongst each teams, though transient gastrointestinal points, like nausea and vomiting, had been almost 30 p.c extra widespread within the liraglutide group.
“Thus far, kids have had just about no choices for treating weight problems,” argues Fox.
“They’ve been informed to ‘attempt tougher’ with weight-reduction plan and train. Now with the opportunity of a medicine that addresses the underlying physiology of weight problems, there may be hope that kids residing with weight problems can stay more healthy, extra productive lives.”
In an accompanying editorial, pediatricians Julian Hamilton-Protect and Timothy Barrett argue that Fox and her colleagues have supplied “much-needed proof” for the results of liraglutide on younger kids with weight problems.
However physique composition was not measured within the trial, and BMI is a poor surrogate for fats mass, they be aware.
After remedy was ceased, kids within the liraglutide group of the trial confirmed elevated BMI scores, “which is worrisome as a result of it implies the continuing want for pharmacotherapy to forestall BMI rebound,” clarify Hamilton-Protect and Barrett.
The identical considerations additionally apply to adults taking these drugs. As soon as the injections are stopped, research have discovered the common affected person sometimes regains about two-thirds of their misplaced weight inside a 12 months.
Vital fluctuations in weight throughout childhood may very well be a critical threat for ongoing growth.
In a commentary printed final 12 months, some scientists (with no conflicts of curiosity to declare) warned that “little consideration has been paid to the potential unintended penalties or opposed affect of those drugs on kids and adolescents throughout their essential interval of development and growth.”
Provided that the long-term unintended effects of incretin mimetics are nonetheless being realized in adults, there’s each purpose to tread cautiously.
The examine was printed within the New England Journal of Medication.
