Weight-loss jab could be made for $3 a month, study finds
Weight-loss jabs such as Wegovy could be made for just $3 a month, according to new analysis, potentially making the treatment available to millions in poorer countries as patents expire.
More than a billion people live with obesity worldwide, with rates rising fast in lower-income nations as they shift to westernised diets and more sedentary lifestyles.
The World Health Organization designated semaglutide – sold to treat obesity under the brand name Wegovy, and diabetes under the brand name Ozempic – as an essential medicine in September last year.
But global health leaders warned at the time that high prices were limiting access.
New research, published as a pre-print, suggests that semaglutide could be mass produced for $3 (about £2.35) for a monthly dose in its injectable form.
Newer formulations, taken as a pill rather than an injection, could be made for about $16 a month.
One of the authors, Dr Andrew Hill of Liverpool University’s pharmacology department, said: “These low prices open the door to worldwide access to an essential medicine.”
The researchers also found that core patents on semaglutide were due to expire in 10 countries this year, including Brazil, China, India, South Africa, Turkey, Mexico and Canada from 21 March, opening the way to generic competition.
They identified another 150 countries where patents had not been filed, including most of Africa. Those 160 countries are home to 69% of people with type 2 diabetes and 84% of those living with obesity.
Another author, Prof François Venter from Witwatersrand University in Johannesburg, said: “Drugs to treat HIV, TB, malaria and hepatitis are available in low- and middle-income countries for prices close to the cost of production, saving millions of lives while allowing generic companies to make sufficient profit to ensure sustainable supply. We can repeat this medical success story for semaglutide.”
The researchers warned that cheaper treatments would not address the structural drivers of obesity, “including food insecurity, poverty, urbanisation and commercial food environments”, and said that coordinated policies and procurement planning would be needed to realise the benefits.
Dr Nomathemba Chandiwana, chief scientific officer at South Africa’s Desmond Tutu Health Foundation, and a specialist in obesity, who was not involved in the study, said: “This could be very significant for South Africa and many African countries and low and middle-income countries [LMICs] at large where cost has been one of the main barriers to access.”
She said analysis suggested about 27% of adults worldwide met the criteria for drugs such as semaglutide “and importantly, most of those live in LMICs where access to these medicines is extremely limited”.
Chandiwana said the key question now was how health systems integrated the drugs responsibly into broader obesity and diabetes care.
Obesity is linked to a host of other health conditions, including heart disease, diabetes, stroke and cancer. There are 3.7 million deaths attributed to excess weight each year.
The number of people living with diabetes rose from 200 million in 1990 to 830 million in 2022, with the steepest rises in low- and middle-income countries.
Semaglutide was first approved by US regulators in 2017, and costs about $200 a month in the US and £120 a month in the UK. Patents in Britain continental Europe and the US do not expire for another five years.
The research is based on shipment records of key ingredients from 2024 and 2025, and uses the same methodology that has been used in the past to accurately predict the prices of generic medicines for HIV, hepatitis C and some cancer drugs.
Its findings follow research by Médecins Sans Frontières in 2024, which found that diabetes drugs including semaglutide could be made and sold much more cheaply.

PCOS: Matter Of Eggs And Far Beyond
Dr. Pooja Vaswani – Consultant Obstetrics & Gynaecology.
NMC Royal Hospital, Abu Dhabi
Quite many times in our daily practice we come across women who are diagnosed to have Polycystic Ovarian Syndrome (PCOS), the incidence of which is on an increase. It affects about 10% of women. It’s the word “PCOS” that catches any woman’s attention, as more often than not she would have heard about PCOS from her friends/ mother or sisters. Immediate question that comes to the mind of the woman is “will I be able to conceive?”
Ofcourse maternal instinct is paramount and being a gynecologist women with PCOS come to me with concerns that are either cosmetic or reproductive. As gynecologist we cater to reproductive goal,however it is to be kept in mind that as a doctor our role does not end there. PCOS has long term implications too which can go far beyond the reproductive age.Many studies confirm that the insulin resistance associated with PCOS can expose women to higher risk of metabolic syndrome which could be a combination of hypertension; hyperlipidemia, diabetes and cardiovascular disease.
Apart from these metabolic disorders, women with PCOS are also at an increased risk of developing endometrial, ovarian and possibly also breast cancer in later life.
There is a need for a holistic approach in dealing with PCOS keeping in mind that contrary to what the name implies, PCOS implications are not restricted just to sex organs but go way beyond, affecting many other organs in the body which can have profound effect on long term health of the women. These women should be evaluated for these conditions accordingly on a more frequent basis.
Every responsible gynecologist should utilize every potential opportunity to evaluate and educate the patients about ways to prevent these potentially threatening long term metabolic and malignant disorders by intervening at the earliest.

Novartis: Rare muscle disease drug shows early promise
Novartis (NOVN.S), opens new tab said on Thursday an experimental drug, which it acquired as part of its $12 billion takeover of Avidity, showed promise in an early-to-mid-stage study in patients with a type of genetic muscle disorder characterized by slowly progressive muscle weakness.
- The Swiss drugmaker said the drug, known as del-brax, lowered two blood markers linked to the disease and showed reduced signs of muscle damage in patients with facioscapulohumeral muscular dystrophy.
- Novartis said the drug shows potential to become the first disease-modifying treatment for FSHD, which can cause weakness in the face, shoulders, arms and other muscles.
- The company estimates it affects about 45,000 to 87,000 people in the U.S. and EU.
- The drug’s safety profile was consistent with previous results, the company said.
- Novartis plans to discuss the data with health regulators around the world, while a late-stage study of the drug is currently enrolling patients.

Obesity drug shows promise in reducing belly and liver fat
Boehringer Ingelheim said on Sunday its experimental obesity drug cut visceral and liver fat while minimizing loss of lean mass in a late-stage study, data showed, bolstering its case for benefits beyond weight loss as competition in obesity drugs intensifies.
The drug, survodutide, was licensed from Denmark’s Zealand Pharma (ZELA.CO), opens new tab. An injectable that mimics the proteins GLP-1 and glucagon to create a feeling of fullness, its weight-loss trial results were announced in April, showing patients lost an average of 16.6% over 76 weeks.
Analysis of a group of patients who had MRI measurements at the start and end of a 76-week trial showed that survodutide reduced harmful abdominal fat by up to 34% and liver fat by up to 63.1% from the baseline, Boehringer said.
Analysts have said the weight-loss numbers were broadly comparable to existing GLP-1 injections from Novo Nordisk (NOVOb.CO), opens new tab and Eli Lilly (LLY.N), opens new tab and below newer rivals in development, and that the company needed to differentiate the drug’s benefits.
Lean mass accounted for no more than 10.8% of the change in body composition at the highest dose of 6 milligrams, suggesting the weight loss was driven mainly by fat reduction.
The drug’s effect on liver-fat reduction and preservation of lean mass are central to whether it will be able to stand out commercially, alongside tolerability and how long patients stay on the drug. Detailed data from the study could help Boehringer make a stronger case that survodutide should be judged not only by pounds lost but by where weight is lost.
“We believe survodutide will become an important new option at the intersection of obesity and liver disease, two conditions that are deeply connected but rarely addressed together,” said Boehringer executive Shashank Deshpande, who leads the company’s human medicines business.
Boehringer acquired the rights in 2011 to solely develop and commercialise survodutide from Zealand, which is entitled to royalty payments on global revenue.
PATIENTS WITH LIVER DISEASE BENEFIT
In a separate late-stage study of overweight or obese patients with a fatty liver disease called MASLD, survodutide met both its main goals.
After 48 weeks, up to 84.2% of patients on the drug showed a liver fat reduction of at least 30%, compared with 24.3% for those on placebo. Patients on survodutide also lost up to 12.2% of their body weight, versus 1% for placebo.
In 61% of the patients the drug helped achieve liver fat normalization, or a liver fat content below 5%, compared with 5.7% on placebo.
U.S. biotech Altimmune (ALT.O), opens new tab is also developing a drug that targets both the appetite-suppressing gut hormone, GLP-1, and glucagon.
Survodutide is also being tested in other late-stage studies, including for patients with fatty liver disease and fibrosis.
