Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This phase II trial tests the effectiveness of cannabidiol (CBD) plant extract (BRC-001) in improving joint stiffness and pain (arthralgia) in women with breast cancer taking aromatase inhibitors (AIs). AIs lower blood levels of estrogen in postmenopausal women to reduce breast cancer recurrence. Women on AI therapy may experience joint stiffness, pain and arthritis symptoms as a side effect of the medication. Some women stop AI therapy due to these side effects and do not receive the maximum benefit from the medication. CBD is derived from the same plant family as marijuana but is not associated with a "high" or mind-altering effect and is not habit-forming. Research in animals and humans indicates that CBD might decrease inflammation in joint tissues and may help reduce chronic pain in ailments such as arthritis. BRC-001 may reduce joint pain in women with breast cancer taking AIs.
