Targeted Radiofrequency ablation of painful metastatic tumor in the vertebral body.

STAR™ Tumor Ablation System

Registry collecting data on use of The STAR™ Tumor Ablation System.

The STAR Prospective Registry is an observational registry to gather clinical safety and outcome data in patients with painful spinal metastases in the thoracolumbar spine (T1-L5) following targeted radiofrequency ablation (t-RFA) treatment with the STAR™ Tumor Ablation System.

Targeted radio-frequency ablation using the STAR™ Tumor Ablation System and vertebral augmentation using the StabiliT® Vertebral Augmentation System.

Radiofrequency-targeted vertebral augmentation (RF-TVA)

Jack Jennings, MD

The purpose of this study is to evaluate treating painful metastatic lesions in vertebral bodies with pathologic fractures with targeted radiofrequency ablation (t-RFA) and vertebral augmentation (VA) prior to or following radiation therapy.

Prospective, multi-center clinical study. Stratification scheme: 'Failed/Refused Further RT' and "No Previous RT"

Evaluation of t-RFA and RF-TVA Prior to/Following Radiation Therapy to Treat Painful Metastatic Vertebral Body Tumor(s)

Evaluation of Targeted Radiofrequency Ablation and Vertebral Augmentation Prior to or Following Radiation Therapy to Treat Painful Metastatic Vertebral Body Tumor(s) [The STARRT Study]

The Brief Pain Inventory (BPI) short form rates pain on a scale from 0 to 10 (with 0=no pain and 10=worst pain you can imagine). The response is from Q3 reporting worst pain within the last 24 hours. Primary outcome is measuring the mean change from baseline in BPI worst pain score at 6 weeks.

Measured by Brief Pain Inventory (BPI) Pain Q3, The Brief Pain Inventory (BPI) short form rates pain on a scale from 0 to 10 (with 0=no pain and 10=worst pain you can imagine). The response is from Q3 reporting worst pain within the last 24 hours. Secondary outcome is measuring the mean change from baseline in BPI worst pain score prior to 6 weeks.

The Brief Pain Inventory (BPI) short form rates pain on a scale from 0 to 10 (with 0=no pain and 10=worst pain you can imagine). The response is from Q3 reporting worst pain within the last 24 hours. Secondary outcome is the response to Q3 at Weeks 1, 2 and 6.

All cause mortality was collected. Of 35 enrolled subjects, 9 died due to disease progression and 2 died due to other reasons (one was listed as hospice and the other as "unknown"). There were 0 participants considered to have experienced Serious Adverse Events (SAEs) and the participants who died due to disease progression and other reasons are not considered SAEs.

The BPI asks subjects to rate pain by circling the one number that best describes pain at its worst in the last 24hrs. 0=no pain and 10=pain as bad as (you) can imagine. Results are presented in response to Q3 of the BPI only (i.e. pain at its worst in the last 24hrs). This was accomplished using the BPI short form.

Brief Pain Inventory (BPI -Short Form) - 24 hour worst pain

Study was terminated due to difficulty with enrollment. Analysis of data is limited due to early termination of study and incomplete enrollment and completion of study subjects.
