Tart cherry and fish oil for aromatase inhibitor–related joint pain

An Open Label, Randomized, Waitlist Controlled Trial of Tart Cherry and Omega-3's for Aromatase Inhibitor Musculoskeletal Symptoms

Early Phase 1 Interventional Cedars-Sinai Medical Center · NCT06123286

This project will test whether taking tart cherry concentrate plus fish oil for 12 weeks reduces joint pain and stiffness in women with breast cancer who are taking aromatase inhibitors.

What this trial studies

This early-phase interventional project gives participants tart cherry concentrate, fish oil, or a combination over a 12-week period to measure changes in joint function and pain. Enrollment targets women with stage I–III breast cancer who are actively receiving aromatase inhibitor therapy and meet specified criteria (including BMI ≥27, Omega-3 index <8%, and average joint pain ≥4). Outcomes will focus on patient-reported joint pain and stiffness, with biochemical and functional measures used as secondary endpoints. The work is conducted at Cedars-Sinai sites in Los Angeles and Torrance, California.

Who should consider this trial

Good fit: Ideal candidates are adult women with stage I–III breast cancer on aromatase inhibitors who have BMI ≥27, an Omega-3 index below 8%, and moderate-to-severe joint pain (average BPI ≥4).

Not a fit: People taking anticoagulant medications, with allergies to cherries or fish, with inflammatory arthritides, uncontrolled diabetes, or a history of stroke/TIA are excluded and unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the combination could offer a lower-risk, supplement-based option to help reduce AIMSS-related pain and stiffness.

How similar studies have performed: Preclinical mouse studies suggest the two supplements may have additive anti-inflammatory effects, but to our knowledge no prior human trials have tested this specific combination for AIMSS.
