Eli Lilly’s (LLY) latest obesity drug did not just clear the bar set by its own blockbuster Zepbound; it appears to have moved the bar, the stadium, and possibly the concession stand.

A new heavyweight in weight loss

In a late-stage trial, Lilly’s “next-gen” injectable cut body weight by an average of 28.7%, translating to roughly 71 pounds lost over 68 weeks for some participants, eclipsing the already eye‑popping results seen with Zepbound. Zepbound itself has helped patients lose around 20% of their body weight in earlier studies, and already outperformed Novo Nordisk’s Wegovy in a head‑to‑head obesity trial, so this newer agent is effectively beating the champion that beat the champion.

Investors, who had just adjusted to the idea of 20% weight loss as the new normal, are now recalibrating their spreadsheets for a world where the “before” picture may soon qualify as historical documentation. Early reports also note meaningful pain relief and functional gains in osteoarthritis patients, hinting that the drug could enter the lucrative realm of treating not just weight, but the orthopedic consequences of carrying it.

Market that keeps expanding

The global obesity drug market, already projected into the tens of billions as GLP‑1 therapies go mainstream, is now straining the adjectives normally reserved for technology bubbles and coastal real estate. Wall Street expects the category to reach well over 100 billion dollars in annual sales within the next decade, with Lilly and Novo Nordisk (NVO) still cast as the main duopoly—though the script now has Lilly in increasingly bold font.

Lilly recently crossed the one‑trillion‑dollar market‑cap threshold, a once‑unthinkable milestone for a pharmaceutical company, largely on the back of its GLP‑1 franchise and investor belief that “next‑gen” is not just marketing copy but a recurring revenue event. Each successful readout reinforces a perception that this pipeline is less a linear sequence of drugs and more a subscription model for better metabolism.

Pipeline as a product line

While the new injectable grabs the headlines, Lilly continues to build a bench of follow‑ons that would make a Silicon Valley platform company jealous. Its once‑daily oral GLP‑1, orforglipron, has shown superior reductions in blood sugar and greater weight loss than oral semaglutide in type 2 diabetes, positioning it as a scalable, needle‑free option that could expand the addressable market far beyond early adopters willing to self‑inject.

Early‑stage assets such as the amylin analog eloralintide, which has produced up to about 20% weight loss in preliminary trials, give Lilly additional shots on goal as combinations and new mechanisms are tested for faster or more durable results. Seven more late‑stage trials of the newest injectable are expected to read out by 2026, setting up a drumbeat of data that could either validate today’s exuberance—or remind markets that biology is not always as linear as the stock chart.

Novo, meet your new normal

Across the street, Novo Nordisk is hardly standing still, with an oral version of Wegovy under regulatory review and a combination of cagrilintide and semaglutide that has delivered around 22% weight loss in prior trials. Yet the narrative has shifted: where the question once was whether Lilly could catch Wegovy, it is now whether Novo’s next wave can catch a moving target whose last drug beat Wegovy and whose latest drug appears intent on beating that.

Payers, meanwhile, face the uniquely modern dilemma of deciding how much they are willing to reimburse for medicines that may meaningfully reduce cardiovascular risk, joint damage, and healthcare utilization over time, while simultaneously threatening short‑term pharmacy budgets. If the weight of evidence continues to build in Lilly’s favor, the bigger challenge for rivals may not be scientific but psychological: convincing physicians and patients to switch away from what increasingly looks like the S&P 500 of waistlines.

Structure Therapeutics has quietly become the GPCR‑focused upstart reminding investors that Lilly and Novo will not have the obesity field to themselves forever.

Structure Enters The GLP-Game!

Structure Therapeutics, which trades under the appropriate ticker “GPCR,” is building an entirely oral, small‑molecule pipeline aimed at GPCR targets for chronic metabolic diseases, with obesity at the center of the story. Its lead program, aleniglipron (GSBR‑1290), is a biased small‑molecule GLP‑1 receptor agonist designed to deliver injectable‑level efficacy in a pill, with dose‑proportional pharmacokinetics and once‑daily dosing that fits neatly into primary‑care workflows.

Phase 2b ACCESS data suggest aleniglipron may have broken what analysts once called the “oral ceiling,” with up to about 15.3% placebo‑adjusted weight loss at 36 weeks for the 240 mg dose and around 11.3% at 120 mg, alongside improvements in blood pressure and HbA1c. Tolerability has looked competitive with GLP‑1 peers so far, with discontinuation rates in the low‑double‑digit range and no apparent liver safety signals, an important differentiator as injectable GLP‑1s face scrutiny over gastrointestinal side effects.

The $650 million war chest

Those data lit a fire under the stock and, more importantly, opened the capital markets door. In early December, Structure priced an upsized public offering of American depositary shares and pre‑funded warrants expected to bring in roughly 650 million dollars in gross proceeds, with underwriters granted a 30‑day option to buy additional ADSs.

For a clinical‑stage company, that haul effectively turns positive Phase 2b obesity data into a multi‑year runway for Phase 3, manufacturing scale‑up, and expansion of its GPCR‑targeted obesity portfolio, including an oral amylin receptor agonist and an apelin receptor program. In a market now obsessed with who can squeeze a few extra percentage points of weight loss out of GLP‑1s, Structure is making the simpler pitch: same biological target class, but with best‑in‑class oral convenience and, thanks to that 650 million dollars, enough cash to try to prove it at scale.

In sum, Structure Therapeutics has quietly become the GPCR‑focused upstart reminding investors that Lilly and Novo will not have the obesity field to themselves forever.
