Cardiology Just Declared War on Obesity. Pemvidutide May Be One of Its Strongest Weapons

Yesterday, the American College of Cardiology made it official. Obesity is no longer just a lifestyle issue. It is a cardiovascular emergency. For the first time, the ACC published clinical guidance focused entirely on the medical management of obesity, urging cardiologists to use every modern tool available to lower cardiovascular risk.

And right on cue, Altimmune released new data at ADA 2025 showing that their GLP-1 and glucagon receptor agonist, pemvidutide, does more than help people lose weight. It cuts inflammation and reshapes the blood chemistry that drives heart disease.

Here’s what the ACC just laid out:

• Obesity is not simple. It is driven by genetics, brain chemistry, trauma, environment, and more

• Cardiologists should approach obesity just like they do high cholesterol or blood pressure

• GLP-1 medications like semaglutide and tirzepatide are the most effective tools currently available

• These drugs already show a reduction in heart attacks, strokes, and cardiovascular deaths, especially in people with type 2 diabetes

• Barriers like cost, insurance delays, and stigma still keep too many people from getting treatment

Now, here’s what Altimmune dropped about Pemvidutide today at ADA:

Trial Overview:

• Phase 2 study

• 391 adults with obesity or overweight, without diabetes

• Randomized to weekly pemvidutide doses of 1.2 mg, 1.8 mg, 2.4 mg, or placebo

• Treatment lasted 48 weeks

What happened:

• Weight loss:

  • Up to 15.6 percent reduction in body weight

• Lipid improvements:

  • Total cholesterol down 15.1 percent

  • LDL cholesterol down 11.2 percent

  • Triglycerides down 34.9 percent

• Inflammation and risk marker changes:

  • Decreased remnant cholesterol

  • Fewer small LDL particles

  • Reductions in multiple proinflammatory lipid classes

  • Significant drop in Glyc A, a biomarker tied to heart failure

This is the kind of data the ACC guidance points toward. Not just shrinking waistlines, but reducing real cardiovascular risk. Not just looking better in photos, but living longer with fewer complications.

Altimmune isn’t trying to be just another weight loss company. They’re positioning pemvidutide as a medicine that rewires the metabolic storm behind obesity, inflammation, and cardiovascular disease. If this pans out in later stage trials, it could be one of the most impactful molecules in the space.

The bigger takeaway:

We’re in the middle of a massive shift. Obesity is being redefined as a medical condition that deserves treatment, not blame. Cardiologists are being told to stop ignoring it. And drugs like pemvidutide are showing up with the concrete data to back that up.

The media coverage might stay focused on the scale. But the real story is happening in the bloodstream. And cardiologists are finally paying attention.
