## In brief

- Two Northwestern University-led Phase III clinical trials tested an experimental weight-loss drug in adults with painful knee osteoarthritis who are overweight or have obesity.
- The trials involved more than 1,000 participants, according to the source.
- The source reports the drug eased pain and improved daily activities such as walking, climbing stairs and standing up from a chair.

## Why it matters

Osteoarthritis treatments that address both pain and body weight could change how clinicians manage knee pain in patients with obesity. Science readers should note that the findings come from Phase III trials of an investigational drug, which is not yet approved.
