Opinion: Canadians can benefit from tumbling prices on weight-loss drugs Affordable semaglutide can improve the health outcomes for the more than 1 billion people living with obesity worldwide

So @petersinger.bsky.social and I just published a piece about the "$6 revolution" in generic GLP-1 drugs in Canada's @theglobeandmail.com.

You can also read the original, longer version, on our Substacks. (see below)

Happy to write this piece with @natashaloder.bsky.social. Canada is in a unique position as the only G7 country which will soon have no patent protections for GLP-1 drugs. The opportunities are humungous. Read more about what we think should happen www.theglobeandmail.com/gift/2be7b2e...

Canadians can benefit from tumbling prices on weight-loss drugs. Canada is in a unique position as the only G7 country where patent protection on semaglutide is about to lapse, by @petersinger.bsky.social @natashaloder.bsky.social www.theglobeandmail.com/opinion/arti... via @theglobeandmail.com

The WHO listing is a step in the right direction. But it’s only advice to governments. Its indications are also pretty conservative: diabetes w/ heart or kidney disease or w/ obesity. WHO could speed up availability by pre-qualifying GLP-1 manufacturers and updating its clinical guidelines.

The $6 revolution. How generic weight loss drugs could save millions of lives. The arrival of generic semaglutide is an unheard of opportunity for global public health

Funding is also needed. @natashaloder.bsky.social & I outline several options for innovative finance for GLP-1 drugs and sketch the huge opportunity as the patent on semaglutide expires in many jurisdictions early next year. Check out our joint piece here: open.substack.com/pub/singerp/...

On Sept 5th, @who.int listed GLP-1 drugs on its Essential Medicines List. This listing covers about 75% of the 2.1 m lives saved per year in the lower estimate of the model David Brook and I developed. See the details on the screenshot below from our preprint: www.medrxiv.org/content/10.1...

GLP-1 drugs have been on the Medicines Patent Pool priority list for a while. Time for the companies to come forward now @who.int labeled them essential @thirugeneva.bsky.social @medicinespatentpool.org

Tomorrow the WHO updates its essential medicines listβ€”which over 150 countries adopt as policy. Will GLP-1 drugs be on the list?

Read my article with @petersinger.bsky.social which explains why such a shift could be an important next step

5/ The World Health Organization needs to step up. GLP-1 drugs deserve inclusion in global obesity strategies. Delay could mean hundreds of thousands of preventable deaths.

1️⃣ Earlier this month, the US health departmentβ€”headed by RFK Jr.β€”terminated $500m contracts supposedly related to mRNA vaccines for respiratory viruses. Debunked safety concerns were cited as the reason.

But far more than this was cut. #Science #Vaccines #HealthPolicy #RNA #mRNA

@natashaloder.bsky.social and I argue that company foundations should be able to promote global access β€” by supporting financial innovations or researchβ€” on products their related companies make in cases of massive public benefits.

In 5 months, semaglutide (Ozempic) goes off patent in parts of the world. Manufacturing cost is about $6/month.

India, China, Brazil, and Canada will get generics. The US, UK, and Europe won't. Yet.

Eventually, this will be dirt cheap for everyone. That's how obesity ends.

3/ This isn’t just about weight loss. These drugs could save up to 3.1M lives per year, as per @petersinger.bsky.social and help with diabetes, improve heart health, and may also impact addiction and dementia risk.

mRNA vaccines can be quickly programmed based on viral genomic sequence. It’s like anti-viral software updates IRL. That quick and nimble nature is what makes them so useful.
