Pfizer‘s latest guess on obesity is already exhibiting promise.
The firm final week stated it might purchase weight reduction drugmaker Metsera in an up to $7.3 billion deal, together with future funds, that’s anticipated to shut on the finish of the 12 months. Just per week later, Metsera launched data from mid-stage trials on its lead obesity drug candidate that may permit the corporate to begin part three research on the therapy later this 12 months.
Metsera, based in 2022, brings a pipeline of each oral and injectable remedies with completely different targets. The firm picked up these medication via its personal licensing and acquisition offers. But all eyes are on Metsera’s injection, MET-097i, which is the furthest alongside in improvement.
The firm is creating the injection to be taken as soon as a month, which might supply a handy edge over the weekly injections at present dominating the market. MET-097i is within the GLP-1 class, which is similar class as Novo Nordisk‘s obesity drug Wegovy and Eli Lilly‘s rival therapy Zepbound.
Early data counsel it might probably ship robust weight reduction with fewer gastrointestinal unwanted effects than the remedies in the marketplace. The new data on Monday seems to again that up – at the least for now.
In a notice Monday, JPMorgan analyst Chris Schott stated, “more broadly, we continue to see MET-097i as one of several emerging competitors that we believe will take some share” from Eli Lilly and Novo Nordisk over time. He referred to as the outcomes “solid,” including that the drug’s total profile seems in keeping with Eli Lilly’s weight reduction drug Zepbound.
Let’s break down the outcomes.
How a lot weight did sufferers lose?
Metsera stated the very best dose of its injection demonstrated weight lack of as much as 14.1% on common after 28 weekly doses in a mid-stage trial referred to as VESPER-1. Some individuals misplaced rather more, with the very best being 26.5% weight reduction.
VESPER-1 has an ongoing extension research that features much less frequent dosing choices. Metsera stated an exploratory evaluation on the finish of the weekly dosing part of the extension at 36 weeks demonstrated “substantial and continued weight loss,” which means that no plateau had occurred.
It’s troublesome to match the outcomes to these of different medication with out head-to-head research, however the weight reduction brought on by Metsera’s injection seems to be encouraging. Wegovy brought on round 15% weight reduction after 68 weeks in bigger part three trials. Zepbound has proven weight reduction above 20% in late-stage research.
The different trial, VESPER-3, is ongoing, so Metsera didn’t report weight reduction data on Monday. That trial is analyzing month-to-month dosing of the injection, with preliminary weight reduction data anticipated by year-end or early 2026, in keeping with the corporate. The drug has a protracted half-life – or the time it takes for the focus of the drug in your physique to cut back by half – which makes once-a-month dosing attainable.
How nicely did sufferers tolerate the drug?
Patients appeared to deal with Metsera’s injection nicely in each research, primarily based on present data. But we nonetheless want extra detailed data from the trials to say whether or not it may be tolerated higher than the injections in the marketplace, whereas additionally providing aggressive weight reduction.
The firm stated at a beginning dose of 0.4 milligrams, its injection was as nicely tolerated as a placebo throughout each trials. Metsera stated gradual, one-to-two step will increase in that dose might give the drug a tolerability edge over rivals within the GLP-1 class.
In VESPER-3, sufferers who regularly elevated their dose to the very best dose – 1.2 milligrams – over 12 weeks noticed “little diarrhea, with only modest increases in nausea and vomiting.” Rates of nausea and vomiting amongst these sufferers had been 13% and 11% above placebo, respectively.
Even at greater doses with out a gradual ramp-up, the injection’s unwanted effects in VESPER-1 had been similar to different accepted weight-loss medication, in keeping with Metsera.
Notably, solely 2.9% of sufferers in that trial – two out of 239 sufferers – stopped therapy as a result of unwanted effects. While it is solely a mid-stage research, that discontinuation charge is encouraging.
Other obesity medication in improvement have reported discontinuation charges nearing 10%, which is barely above that of the prevailing remedies in the marketplace.
Overall, we nonetheless wish to see late-stage trials on MET-097i and Metsera’s different medication. If every thing goes as deliberate, the corporate’s pipeline might ship sizable returns for Pfizer down the road.
In a notice final week, Leerink Partners analyst David Risinger stated the agency estimates Metsera’s obesity candidates have the potential to generate greater than $5 billion in mixed peak annual gross sales.
We’ll make sure to cowl them carefully, so keep tuned.
