Beyond Local: Obesity drug Wegovy cut risk of serious heart problems by 20%, study finds

Published

 on

The popular weight-loss drug Wegovy reduced the risk of serious heart problems by 20% in a large, international study that experts say could change the way doctors treat certain heart patients.

The research is the first to document that an obesity medication can not only pare pounds, but also safely prevent a heart attack, stroke or a heart-related death in people who already have heart disease — but not diabetes.

The findings could shift perceptions that the new class of obesity drugs are cosmetic treatments and put pressure on health insurers to cover them.

“It moves from a kind of therapy that reduces body weight to a therapy that reduces cardiovascular events,” said Dr. Michael Lincoff, the study’s lead author and a heart expert at the Cleveland Clinic.

Wegovy is a high-dose version of the diabetes treatment Ozempic, which already has been shown to reduce the risk of serious heart problems in people who have diabetes. The new study looked to see if the same was true in those who don’t have that disease.

Experts have known for years that losing weight can improve heart health, but there hasn’t been a safe and effective obesity medication proven to reduce specific risks, said Dr. Francisco Lopez-Jimenez, a heart expert at the Mayo Clinic. He expects the new findings to change treatment guidelines and “dominate the conversation” for years to come.

“This is the population who needs the medicine the most,” said Lopez-Jimenez, who had no role in the study.

In the U.S., there are about 6.6 million people like those tested in the study, experts said.

The results were published Saturday in the New England Journal of Medicine and presented at a medical conference in Philadelphia. Novo Nordisk, the maker of Wegovy and Ozempic, has asked the U.S. Food and Drug Administration to include the heart benefits on Wegovy’s label, like on Ozempic’s.

The new study, paid for by the company, included more than 17,500 people in 41 countries. Participants were age 45 and older, had a body mass index of 27 or higher and were tracked for more than three years on average. They took typical drugs for their heart conditions, but they were also randomly assigned to receive weekly injections of Wegovy or a dummy shot.

The study found that 569, or 6.5%, of those who got the drug versus 701, or 8%, of those who received the dummy shot had a heart attack or stroke or died from a heart-related cause. That’s an overall reduction of 20% in the risk of those outcomes, the researchers reported.

The drop appeared to be fueled primarily by the difference in heart attacks, but the number of serious health complications reported were too small to tell whether the individual outcomes were caused by the drug or by chance.

Study volunteers who took Wegovy lost about 9% of their weight while the placebo group lost less than 1%.

The Wegovy group also saw drops in key markers of heart disease, including inflammation, cholesterol, blood sugars, blood pressure and waist circumference, noted Dr. Martha Gulati, a heart expert at Cedars-Sinai Medical Center in Los Angeles. Changes in those markers began early in the study, before participants lost much weight.

“It means to me that it’s more than just weight loss, how this drug works,” said Gulati, who had no role in what she called a landmark study.

Still, “it remains unclear” how much of the results were a benefit of losing weight or the drug itself, an editorial accompanying the study noted.

About a third of all study volunteers reported serious side effects. About 17% in the Wegovy group and about 8% in the comparison group left the study, mostly because of nausea, vomiting, diarrhea and other stomach-related problems.

Nearly three-quarters of participants were men and nearly 84% were white. Gulati and others said future research needs to include more women and racial and ethnic minorities.

Wegovy is part of a new class of injectable medications for obesity. On Wednesday, the U.S. Food and Drug Administration approved Eli Lilly’s Zepbound, a version of the diabetes drug Mounjaro, for weight control.

Both carry high price tags — monthly costs are about $1,300 for Wegovy and about $1,000 for Zepbound. And both have been in shortage for months, with manufacturers promising to boost supplies.

The medications are often not covered by private health insurance or subject to strict preauthorization requirements. Medicare, the government health plan for older Americans, is prohibited from covering drugs for weight loss alone. But drugmakers and obesity treatment advocates have been pushing for broader coverage, including asking Congress to pass legislation to mandate that Medicare pay for the drugs.

Results from the latest study and others that show the obesity drugs have a direct effect on costly health problems could be a factor in shifting the calculus of coverage, said Dr. Mark McClellan, former chief of the Centers for Medicare and Medicaid Services and the FDA. In 2006, Medicare was allowed to cover weight-loss surgery to treat the complications of severe obesity, if not obesity itself, he noted.

That approach “may end up being relevant here,” he said.

Canada to donate up to 200,000 vaccine doses to combat mpox outbreaks in Africa

Published

 on

 

The Canadian government says it will donate up to 200,000 vaccine doses to fight the mpox outbreak in Congo and other African countries.

It says the donated doses of Imvamune will come from Canada’s existing supply and will not affect the country’s preparedness for mpox cases in this country.

Minister of Health Mark Holland says the donation “will help to protect those in the most affected regions of Africa and will help prevent further spread of the virus.”

Dr. Madhukar Pai, Canada research chair in epidemiology and global health, says although the donation is welcome, it is a very small portion of the estimated 10 million vaccine doses needed to control the outbreak.

Vaccine donations from wealthier countries have only recently started arriving in Africa, almost a month after the World Health Organization declared the mpox outbreak a public health emergency of international concern.

A few days after the declaration in August, Global Affairs Canada announced a contribution of $1 million for mpox surveillance, diagnostic tools, research and community awareness in Africa.

On Thursday, the Africa Centres for Disease Control and Prevention said mpox is still on the rise and that testing rates are “insufficient” across the continent.

Jason Kindrachuk, Canada research chair in emerging viruses at the University of Manitoba, said donating vaccines, in addition to supporting surveillance and diagnostic tests, is “massively important.”

But Kindrachuk, who has worked on the ground in Congo during the epidemic, also said that the international response to the mpox outbreak is “better late than never (but) better never late.”

“It would have been fantastic for us globally to not be in this position by having provided doses a much, much longer time prior than when we are,” he said, noting that the outbreak of clade I mpox in Congo started in early 2023.

Clade II mpox, endemic in regions of West Africa, came to the world’s attention even earlier — in 2022 — as that strain of virus spread to other countries, including Canada.

Two doses are recommended for mpox vaccination, so the donation may only benefit 100,000 people, Pai said.

Pai questioned whether Canada is contributing enough, as the federal government hasn’t said what percentage of its mpox vaccine stockpile it is donating.

“Small donations are simply not going to help end this crisis. We need to show greater solidarity and support,” he said in an email.

“That is the biggest lesson from the COVID-19 pandemic — our collective safety is tied with that of other nations.”

How many Nova Scotians are on the doctor wait-list? Number hit 160,000 in June

Published

 on

 

HALIFAX – The Nova Scotia government says it could be months before it reveals how many people are on the wait-list for a family doctor.

The head of the province’s health authority told reporters Wednesday that the government won’t release updated data until the 160,000 people who were on the wait-list in June are contacted to verify whether they still need primary care.

Karen Oldfield said Nova Scotia Health is working on validating the primary care wait-list data before posting new numbers, and that work may take a matter of months. The most recent public wait-list figures are from June 1, when 160,234 people, or about 16 per cent of the population, were on it.

“It’s going to take time to make 160,000 calls,” Oldfield said. “We are not talking weeks, we are talking months.”

The interim CEO and president of Nova Scotia Health said people on the list are being asked where they live, whether they still need a family doctor, and to give an update on their health.

A spokesperson with the province’s Health Department says the government and its health authority are “working hard” to turn the wait-list registry into a useful tool, adding that the data will be shared once it is validated.

Nova Scotia’s NDP are calling on Premier Tim Houston to immediately release statistics on how many people are looking for a family doctor. On Tuesday, the NDP introduced a bill that would require the health minister to make the number public every month.

“It is unacceptable for the list to be more than three months out of date,” NDP Leader Claudia Chender said Tuesday.

Chender said releasing this data regularly is vital so Nova Scotians can track the government’s progress on its main 2021 campaign promise: fixing health care.

The number of people in need of a family doctor has more than doubled between the 2021 summer election campaign and June 2024. Since September 2021 about 300 doctors have been added to the provincial health system, the Health Department said.

“We’ll know if Tim Houston is keeping his 2021 election promise to fix health care when Nova Scotians are attached to primary care,” Chender said.

Newfoundland and Labrador monitoring rise in whooping cough cases: medical officer

Published

 on

 

ST. JOHN’S, N.L. – Newfoundland and Labrador‘s chief medical officer is monitoring the rise of whooping cough infections across the province as cases of the highly contagious disease continue to grow across Canada.

Dr. Janice Fitzgerald says that so far this year, the province has recorded 230 confirmed cases of the vaccine-preventable respiratory tract infection, also known as pertussis.

Late last month, Quebec reported more than 11,000 cases during the same time period, while Ontario counted 470 cases, well above the five-year average of 98. In Quebec, the majority of patients are between the ages of 10 and 14.

Meanwhile, New Brunswick has declared a whooping cough outbreak across the province. A total of 141 cases were reported by last month, exceeding the five-year average of 34.

The disease can lead to severe complications among vulnerable populations including infants, who are at the highest risk of suffering from complications like pneumonia and seizures. Symptoms may start with a runny nose, mild fever and cough, then progress to severe coughing accompanied by a distinctive “whooping” sound during inhalation.

“The public, especially pregnant people and those in close contact with infants, are encouraged to be aware of symptoms related to pertussis and to ensure vaccinations are up to date,” Newfoundland and Labrador’s Health Department said in a statement.

Whooping cough can be treated with antibiotics, but vaccination is the most effective way to control the spread of the disease. As a result, the province has expanded immunization efforts this school year. While booster doses are already offered in Grade 9, the vaccine is now being offered to Grade 8 students as well.

Public health officials say whooping cough is a cyclical disease that increases every two to five or six years.

Meanwhile, New Brunswick’s acting chief medical officer of health expects the current case count to get worse before tapering off.

A rise in whooping cough cases has also been reported in the United States and elsewhere. The Pan American Health Organization issued an alert in July encouraging countries to ramp up their surveillance and vaccination coverage.
