Summary

Background:

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.

Objective:

To learn whether RTX is safe and can reduce cancer induced bone pain.

Eligibility:

People ages 18 and older with CIBP that is not relieved by standard treatments

Design:

Participants will have up to 6 outpatient visits over about 7 months. These will include:

Medical history

Physical exam

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

Chest x-ray

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.

Conditions

  • Intractable Pain
  • Palliative Care

Interventions

DRUG

Resiniferatoxin

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.
