BudNextGen Research Project
A regenerative moonshot for osteoarthritis

Rebuilding the joint, with a single injection.

UCLA, Duke University, and Boston Children's Hospital are working under the ARPA-H NITRO program to develop a regenerative injectable therapy that heals bone and cartilage — moving osteoarthritis care from symptom management to true joint repair.

I   The Project

Osteoarthritis affects 32.5 million people in the United States. There is no cure. The BudNextGen project sets out to change that.

Our team is treating the joint as a single living organ — looking for biologics that can heal cartilage and bone together, rather than managing pain or replacing the joint entirely. The goal is a therapy that is not only effective, but accessible and affordable to anyone who needs it.

The work is part of the Advanced Research Projects Agency for Health's NITRO program, which gives multidisciplinary teams an unusually short runway — five years from concept to a Phase 1 clinical trial. UCLA leads the clinical trial portion of this collaboration, drawing on the diverse patient population, clinical infrastructure, and translational research environment of UCLA Health and the David Geffen School of Medicine.

II   The Clinical Trial

The clinical trial at UCLA, beginning October 2027.

1

Who can take part

Adults living with mild-to-moderate osteoarthritis of the knee. Specific eligibility criteria will be defined by the study protocol and reviewed with each participant during screening.

2

What is involved

A single injection of the investigational regenerative therapy, delivered at UCLA. No surgery is required as part of the trial.

3

How participants are followed

Six months of follow-up visits with the study team, including pain outcome assessments and imaging, to track how the joint responds over time.

4

Where the trial is conducted

The trial is centralized at UCLA, with referral partnerships across UC Health and community clinics serving populations historically underrepresented in osteoarthritis research.

If we develop a viable therapy through NITRO, it has the potential to impact millions of people. The opportunity of a lifetime.
