Pfizer Bets Big on Chinese Weight-Loss Drug in Race to Catch Market Leaders

Pfizer is paying up to $2.09 billion for global rights to Fosun Pharma's experimental obesity pill, adding another asset to its pipeline as it scrambles to compete in the booming GLP-1 market where rivals Novo Nordisk and Eli Lilly have raced ahead.

The pattern is getting predictable by now: another Chinese pharmaceutical company has landed a licensing deal with a Big Pharma giant for a weight-loss treatment. This time it's Pfizer Inc. (PFE) teaming up with Shanghai Fosun Pharmaceutical (Group) Co. Ltd., and the stakes are substantial.

Pfizer is essentially playing catch-up in the anti-obesity business, a market where it's been watching from the sidelines as competitors rake in billions. The company has agreed to pay up to $2.09 billion for worldwide rights to an experimental oral weight-loss pill that's still in early development. It's a big bet, but given how badly Pfizer needs a winner in this space, it might be a necessary one.

The Deal Structure

Here's how the money breaks down: Fosun Pharma's subsidiary Yao Pharma gets $150 million upfront, with another $350 million potentially coming from hitting clinical and commercial milestones. Then there are sales-related payments that could reach $1.59 billion if everything goes perfectly. That's the optimistic scenario, of course.

The drug in question, YP05002, is an oral small-molecule GLP-1 receptor agonist. Translation: it's a pill that helps regulate blood sugar and suppress appetite by controlling insulin and glucagon secretion while slowing digestion. Beyond obesity, it's being developed for Type 2 diabetes and metabolic dysfunction-associated steatohepatitis (MASH), the liver disease formerly known as NASH.

What's particularly interesting is that YP05002 is currently undergoing Phase One trials in Australia. Phase One. That's about as early-stage as you can get in drug development, which explains why Pfizer negotiated an escape hatch. The company can terminate the agreement with just 60 days' written notice if the trials don't deliver. Smart move, considering the high failure rate at this stage.

Why This Matters for Pfizer

The GLP-1 market has exploded into one of pharma's hottest sectors. In the first three quarters of 2025 alone, Novo Nordisk's semaglutide generated $25.46 billion in sales, up 24% year-over-year. Eli Lilly's tirzepatide did even better, more than doubling to $24.84 billion and representing 49% of the company's total revenue. Combined, these two drugs brought in nearly $50 billion in nine months.

Pfizer, meanwhile, has been stuck on the sidelines. The company discontinued two of its own GLP-1 candidates due to adverse effects, leaving a significant hole in its pipeline right when the market took off. This is particularly painful timing because several of Pfizer's blockbuster products are losing patent protection over the next three years.

Remember 2022? That was Pfizer's peak moment, when Covid vaccine revenues pushed total sales past $100 billion, making it the world's top pharmaceutical company. Those days are gone. Now the company is scrambling to refill its pipeline through acquisitions and licensing deals.

Since the second half of 2024, Pfizer has been on a shopping spree. It signed a deal worth up to $6 billion with China's 3SBio for an experimental cancer drug. It acquired U.S. biopharma firm Metsera for $10 billion to get weight-loss assets. The Fosun Pharma collaboration is just the latest move in this strategy.

The Oral Advantage

Oral GLP-1 drugs have obvious appeal compared to injectable versions. Nobody enjoys giving themselves shots, and pills are simply more convenient. But existing oral formulations have their own problems: low absorption rates and the requirement to take them on an empty stomach limit their practicality.

If small-molecule oral drugs like YP05002 can overcome these limitations, they could offer a real advantage in terms of patient compliance. People are more likely to stick with a treatment regimen when it's easier to follow. That's not just good for patients; it's good for sales.

Fosun's Strategic Shift

This deal represents a meaningful moment for Fosun Pharma, which has been deliberately transitioning from generic medications toward innovative drugs. The company's first three quarters of 2025 painted an interesting picture: operating revenue fell 4.91% to 29.39 billion yuan ($4.17 billion), but net profit surged 25.5%.

How do you lose revenue while profit jumps? Asset sales. Fosun Pharma has been selling off subsidiaries and non-core assets while blaming the revenue decline on pricing pressure from China's centralized drug procurement system. Meanwhile, it's channeling resources into R&D for new drugs.

That strategy appears to be working. Revenue from innovative drugs rose 18.09% to more than 6.7 billion yuan in the first three quarters, emerging as the company's primary growth engine.

The Pfizer partnership delivers immediate cash and something potentially more valuable: global visibility. Chairman Chen Yuqing called it "another important milestone in the company's innovation and internationalization strategy," which sounds like corporate speak but actually captures what's happening here.

Market Context

Fosun Pharma isn't the first Chinese drugmaker to strike this kind of deal. Hansoh Pharma previously sold rights to an oral GLP-1 drug to Merck, while Eccogene made a licensing agreement with AstraZeneca for an early-stage asset in the same category. Chinese pharmaceutical companies are developing these drugs domestically, then partnering with Western giants who have the resources and infrastructure to conduct global trials and commercialize products worldwide.

From a valuation perspective, Fosun Pharma trades at a price-to-earnings ratio around 17 times. Compare that to Hengrui Pharma, another established Chinese drugmaker pivoting toward innovative medicines, which trades at about 59 times earnings. If Fosun successfully executes its transition strategy, there could be room for multiple expansion.

Investors will be watching closely as the company continues divesting non-core assets and funneling capital into drug innovation. The Pfizer deal provides validation that the strategy is attracting serious international interest.

For Pfizer, the pressure is on to find a winner in the obesity market. With an escape clause built into the contract, the company has protected itself from throwing good money after bad. But it also needs something to work. The GLP-1 market isn't slowing down, and sitting on the sidelines isn't a viable long-term strategy when billions of dollars are at stake.
