Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This pilot trial is testing a digital health program called CHALAANE, which means 'walk' in Hindi and Urdu, for South Asian adults with knee osteoarthritis and obesity. The program combines a smartband, an AI-powered mobile app for tracking diet and activity, and a 12-week supervised group walking and lifestyle education component. The study will include 50 participants aged 40 to 75, randomly assigned to either the full program or a control group with an inactive smartband. The main goal is to see if a larger study is feasible, while also gathering early data on pain, physical function, and body composition.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
A digital health program combining a smartband, an AI-powered mobile app for diet and activity tracking, and a 12-week supervised group walking and lifestyle education component.
What this could lead to
If successful, this program could offer a practical, culturally tailored way to help South Asian adults with knee osteoarthritis and obesity improve pain, physical function, and weight management.
What could go wrong
This is a small pilot study focused on feasibility, not proof of effectiveness. The program may not be acceptable or feasible for all participants, and any benefits seen may not persist or generalize to a larger population.
