What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a new drug called LY3541105 to see if it is safe and well-tolerated. The study involves healthy and overweight participants to understand its effects on different body types. Researchers will take blood samples to see how much of the drug gets into the bloodstream and how long it stays there.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug LY3541105 for obesity?

Research on a similar drug, LY3437943, which targets the same receptors, showed it helped reduce body weight and improve blood sugar control in obese mice and had a lasting weight loss effect in humans after a single dose.12345

Published Research Related to This Trial

LY3437943 is a novel triple agonist that targets three receptors related to metabolism, showing promising results in obese mice by reducing body weight and improving blood sugar control.
In a phase 1 study, LY3437943 demonstrated a safety profile similar to existing treatments and supported once-weekly dosing, with weight loss effects lasting up to 43 days after a single dose.

In a 16-week study involving 140 overweight adults, the herbal extract LI85008F led to significant weight loss (5.36 kg) and reductions in BMI compared to a placebo group, indicating its efficacy for weight management.
Participants taking LI85008F also experienced improvements in their lipid profiles, with decreased LDL cholesterol and increased HDL cholesterol, and no major adverse events were reported, highlighting its safety.

The combination of phentermine and topiramate is currently the most effective FDA-approved treatment for obesity, followed by lorcaserin and bupropion/naltrexone.
Effective obesity management should consider not only medication efficacy but also comorbidities, drug interactions, and personalized treatment approaches based on individual genetic profiles.
