Cancer-induced bone pain (CIBP) is common in people with cancer. Bone cancer can also lead to anxiety, depression, and reduced mobility and quality of life. Researchers believe a research drug called resiniferatoxin (RTX) may be able to help.
To learn whether RTX is safe and can reduce cancer induced bone pain.
People ages 18 and older with CIBP that is not relieved by standard treatments
Participants will have up to 6 outpatient visits over about 7 months. These will include:
Blood and urine tests.
Thermal testing: a disk placed on the skin to test ability to sense temperature in and around the area of pain
EKG: stickers are placed on the chest to measure heart signals
ECG: measures electrical activity of the heart
Participants will have 1 inpatient visit lasting 2-4 days. This will include:
Catheter inserted into a vein in the arm. They are given anesthesia, sedation, and x-ray contrast.
A needle is passed through the skin of the back to inject the RTX.
Participants will keep a log of the pain medications they take after surgery.
Participants will be called 1 week and 2, 3, and 4 months after the injection.
Participants will be mailed surveys and questionnaires to complete 2, 3, and 4 months after the injection.

Patient receives one dose of Resiniferatoxin intrathecally
Resiniferatoxin (RTX) is an ultrapotent agonist analog of capsaicin that targets a receptor expressed on specific dorsal root sensory ganglia (DRG) neurons and is expected to reduce pain within the targeted zone.
- The primary outcome is to achieve a dose-response relationship for safety [ Time Frame: 30, 60, 90, and 180 days ]
- substantially reduced pain; improved pain relief; substantially reduced concomitant opioid analgesic consumption; improved quality of life [ Time Frame: 30, 60, 90, and 180 days ]
