Cryoablation Combined With Stereotactic Body Radiation Therapy for the Treatment of Painful Bone Metastases, the CROME Trial
Study Details
Study Description
Brief Summary
This trial compares cryoablation combined with stereotactic body radiation therapy to stereotactic body radiation therapy alone to see how well they work in treating patients with pain from cancer that has spread to the bones (bone metastases). Bone is a common site of metastasis in advanced cancer, and bone metastases often result in debilitating cancer-related pain. The current standard of care to treat painful bone metastases is radiation therapy alone. However, many patients do not get adequate pain relief from radiation therapy alone. Another type of therapy that may be used to provide pain relief from bone metastases is cryoablation. Cryoablation is a procedure in which special needles are inserted into the tumor site. These needles grow ice balls at their tips to freeze and kill cancer cells. The goal of this trial is to compare how well cryoablation in combination with radiation therapy works to radiation therapy alone when given to cancer patients to provide pain relief from bone metastases.

Detailed Description
PRIMARY OBJECTIVE:
- To determine the efficacy of cryoablation in combination with stereotactic body radiation therapy (SBRT) or SBRT only for the treatment of painful bone metastases.
SECONDARY OBJECTIVES:
-
To assess for narcotics utilization by daily morphine equivalent dose. II. To assess duration of pain response reported by International Pain Response Criteria.
-
To assess for local tumor control. IV. To assess for changes in patient quality of life with Brief Pain Inventory (BPI) score.
-
To assess for adverse event rates. VI. To assess incidence and severity of adverse events/toxicity. VII. To assess technical success for cryoablation.
EXPLORATORY OBJECTIVE:
- To investigate the local microenvironmental changes following SBRT and cryoablation combined with SBRT to bone metastases.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A: Patients undergo stereotactic body radiation therapy for 1 fraction.
ARM B: Patients undergo cryoablation. Within 10 days after cryoablation, patients undergo stereotactic body radiation therapy for 1 fraction.
After completion of study treatment, patients are followed up at 1, 2, 3, 4, 8, 12, 16, 20, and 24 weeks.

Outcome Measures
Primary Outcome Measures
- Pain response [At 12 weeks post-treatment]
Defined as complete or partial response as reported by the International Pain Response Criteria at the site of the treated bone metastasis based on the BPI pain score and daily morphine equivalent (MEDD). Will be summarized separately for each treatment arm with associated 95% exact confidence intervals.
Secondary Outcome Measures
- Daily morphine equivalent (MEDD) [Baseline, assessed up to 24 weeks post-treatment]
- Duration of response [Up to 24 weeks post-treatment]
Will be assessed by performing area under the curve (AUC) analysis of Brief Pain Inventory (BPI) pain scores.
- Local control [Up to 24 weeks post-treatment]
Will be determined by imaging evidence of residual viable tumor. Standard of care cross-sectional imaging and bone scintigraphy will be performed at 3 month intervals.
- Rate and severity of adverse and serious related adverse events [Within 30 days of the last study treatment]
Point estimates and two-sided 95% confidence intervals will be generated for procedural related adverse events.
- Technical success for cryoablation [Up to 24 weeks post-treatment]
Will be determined by identifying on intra-procedural imaging when the leading edge of the ice successfully extends beyond the tumor margin by at least 5 mm.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Patient must have a primary diagnosis of malignancy and radiographic evidence of bone metastases. Eligible tumor histologies include the following malignancies with low alpha/beta ratios: renal cell carcinoma, urothelial carcinomas, castration-resistant prostate cancer, sarcoma, thyroid carcinoma, colorectal carcinoma, and melanoma
-
A target lesion the meets the following criteria:
-
The target lesion must be amenable to both cryoablation and SBRT, as determined by the study principal investigators (PIs)
-
The target lesion must be =< 7cm
-
The pain due to the target lesion must be at least 4/10 based on the BPI pain scale
-
Pain from the metastatic site must correlate with an identifiable tumor on computed tomography (CT), magnetic resonance imaging (MRI), or ultrasound (US) imaging
-
Life expectancy >= 3 months
-
Platelet count > 50,000/mm^3 within 6 weeks of screening

Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply: Women < 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization. Women >= 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses > 1 year ago, had chemotherapy-induced menopause with last menses > 1 year ago, or underwent surgical sterilization
