The anti-obesity treatment semaglutide could assist to stop coronary heart assaults, strokes, and different main hostile cardiovascular occasions (MACE) in addition to demise in adults with obese or weight problems who haven’t got diabetes, whether or not or not in addition they have impaired kidney perform, in accordance with new analysis to be offered at this yr’s Annual Assembly of The European Affiliation for the Examine of Diabetes (EASD), Madrid (9-13 Sept).
The outcomes are based mostly on a pre-specified evaluation of the SELECT trial which discovered that adults with obese or weight problems however not diabetes taking semaglutide for greater than 3 years had a 20% decrease threat of MACE or demise as a consequence of heart problems, and misplaced a mean 9.4% of their body weight.Â
This new evaluation discovered the same proportion discount in heart problems with semaglutide in these with and with out poor kidney perform in SELECT. As a result of these with poor kidney perform have greater background threat of heart problems absolutely the profit is biggest on this group.”

She added: “These findings have vital scientific implications. Individuals with impaired kidney perform have elevated dangers of heart problems and the outcomes present that semaglutide is secure and efficient in lowering this threat considerably.”
Weight problems is strongly related to diabetes and persistent kidney illness, and is understood to exacerbate the chance of kidney perform decline and macroalbuminuira (irregular quantities of the albumin protein in urine).
Semaglutide is a GLP-1 treatment primarily prescribed for adults with sort 2 diabetes however on the 2.4mg dose is permitted for weight reduction in folks with weight problems or obese who’ve not less than one different well being problem. This class of medicines simulate the capabilities of the physique’s pure incretin hormones, which assist to decrease blood sugar ranges after a meal. Adjusting these hormone ranges may also make folks really feel full, and in doing so, helps decrease their every day calorie consumption.
Between October 2018 and June 2023, 17,604 adults (aged 45 or older; 72% male) from 804 websites in 41 international locations with obese or weight problems (BMI of 27 kg/m² or greater) had been enrolled within the SELECT trial and handled with semaglutide (2.4mg) or placebo for a mean of 40 months.
They’d beforehand skilled a coronary heart assault, stroke and/or had peripheral artery illness, however didn’t have sort 1 or sort 2 diabetes once they joined the research.
The brand new evaluation examined whether or not semaglutide’s impact on MACE and a mixed endpoint of MACE or demise from any trigger is maintained in members with impaired kidney perform, outlined as low filtration charges and excessive ranges of protein within the urine. This was measured in accordance with estimated glomerular filtration fee (eGFR; a measure of kidney perform in eradicating waste and extra water from the blood via urine) and albuminuria standing at randomisation.
At randomisation, 1,908 (11%) members had eGFR <60 mL/min/1.73 m2Â and a couple of,281 (13%) had urinary albumin-to-creatinine ratio (UACR) of not less than 30 mg/g (indicating impaired kidney perform).
Over a median follow-up of three.5 years, semaglutide was linked to an 18% discount in MACE (6% within the semaglutide group had such occasions vs. 7.3% within the placebo group), in addition to an 18% discount in MACE or demise from any trigger in adults with regular kidney perform (eGFR ≥60).
In members with impaired kidney perform (eGFR <60) semaglutide was linked to a 31% discount in MACE (9.7% semaglutide vs. 13.5% placebo), and a 33% decrease threat of MACE or demise from any trigger.
The researchers additionally discovered that in members with regular ranges of AUCR (<30), semaglutide was linked to a 20% discount in MACE (5.9% semaglutide vs. 7.3% placebo), in addition to a 21% diminished threat of MACE or all-cause mortality.
Equally, in members with greater ranges of UACR (≥30), indicating kidney harm or illness, semaglutide was linked to a 20% discount in MACE in contrast with placebo (9.9% vs 12.3%) and a 19% decrease threat of MACE or demise from any trigger.
Amongst these with impaired kidney perform (eGFR <60) severe hostile occasions had been reported in 37% of these allotted to semaglutide in comparison with 46% of these on placebo.
“The SELECT trial confirmed the advantages of semaglutide for adults with heart problems who had been residing with weight problems or obese however did not have diabetes. This new evaluation finds that inside this group, folks with impaired kidney perform had a lot greater charges of heart problems,” mentioned Professor Colhoun.
“Nonetheless, semaglutide was not less than as efficient at stopping coronary heart assaults and different main cardiac occasions in addition to deaths on this group because it was in these with regular kidney perform. The findings add to the rising proof of the cardiovascular advantages of semaglutide and underscore its vital function as a therapy possibility within the administration of cardiovascular and renal well being for the rising variety of folks affected by weight problems.”
Regardless of the vital findings, the authors warning that SELECT was not a major prevention trial, so the outcomes can’t be extrapolated to sufferers with kidney failure on the whole.
