As standard as the brand new group of weight-loss medicine like Wegovy and Zepbound are, not everybody responds to them in the identical means.
In a brand new presentation on the Digestive Disease Week convention in Washington, Mayo Clinic affiliate professor of medication Dr. Andres Acosta reported {that a} genetic check he developed can determine which individuals are probably to answer semaglutide (Wegovy) and which aren’t.
The check, referred to as MyPhenome, from an organization Acosta co-founded referred to as Phenomix, depends on a mix of genetic and different components to categorize folks into several types of weight acquire. Acosta recognized about two dozen genes linked to weight problems, and greater than 6,000 variants of those genes, to kind individuals who wrestle with weight acquire into 4 classes:
- Hungry Brain: People by no means really feel full, regardless of how a lot they eat
- Hungry Gut: People eat till they’re full however then really feel hungry once more an hour or so later
- Emotional Hungry: Those who eat to deal with emotional points or to reward themselves, no matter their physiological alerts of starvation
- Slow Burn: People who merely aren’t in a position to burn energy as rapidly as they take them in.
In his newest presentation (the outcomes of which haven’t but been revealed in a journal), Acosta stories that the MyPhenome check for Hungry Gut predicts with 75% accuracy who will reply to semaglutide.
“That comes with enormous implications—first for the affected person, as a result of there isn’t any extra trial and error, and second, as a doctor, I wish to know which of my sufferers will reply as a result of I’m asking them to spend $1,000 a month or pay a excessive copay if their insurance coverage covers the medicine,” he says. Having a greater thought of whether or not an individual will reply to medicine like Wegovy may additionally relieve entry points by steering solely the most effective candidates towards it. “This may change the best way we handle weight problems,” he says.

The examine concerned a small variety of sufferers—84 individuals who had been obese or overweight, solely a few of whom had diabetes—who offered a saliva pattern for the MyPhenome check for genetic evaluation and likewise answered a questionnaire about their consuming habits. Each took semaglutide for a yr, and most reached the utmost dose. Because the Hungry Gut profile includes urge for food, and semaglutide works by suppressing the need to eat, Acosta discovered that individuals who match into this class had been probably to lose essentially the most weight on semaglutide. In the examine, 51 of the 84, or about 60%, had been categorised as Hungry Gut.
“Patients with Hungry Gut misplaced 19.5% of their physique mass after a yr, in comparison with 10% for many who had been Hungry Gut unfavourable,” says Acosta. “That’s virtually double the quantity of weight reduction. For the primary time, we will determine the most effective responders.”
Acosta and his group say bigger research replicating these preliminary findings have to be accomplished earlier than the check can be utilized extra extensively. For now, docs can order the MyPhenome check for sufferers from Phenomix’s web site and use it as one other piece of knowledge to assist them and their sufferers resolve if the drug is an efficient match.
“My dream is to deal with continual illnesses like weight problems in the identical means we deal with most cancers—in a really precision-based method,” says Acosta concerning the subsequent steps for the check. It’s additionally attainable that as extra next-generation weight reduction medicine are accredited, pharmaceutical firms might concurrently develop screening assessments to determine people who find themselves probably to profit from their medicine. Insurers can also begin counting on such assessments in making reimbursement selections to make sure that sufferers are receiving the suitable therapies for them.
Acosta says the potential of the check isn’t restricted to semaglutide. For some folks, among the older weight-loss medicines could also be simply as efficient, however till now, docs relied on a trial and error technique of prescribing them. With extra exact methods to matching sufferers to the medicines that work for them, all the current weight-loss medicine might be higher optimized to the suitable sufferers.
