Zoledronate in Treating Patients With Solid Tumors That Have Spread to the Bone
RATIONALE: Zoledronate may help to relieve some of the symptoms caused by bone metastases. It is not yet known if zoledronate is more effective than no further therapy in relieving symptoms of bone metastases or preventing disease progression.
PURPOSE: Randomized phase III trial to determine the effectiveness of zoledronate in treating patients who have solid tumors that have spread to the bone.
Hypercalcemia of Malignancy
Unspecified Adult Solid Tumor, Protocol Specific
Drug: zoledronic acid
Procedure: quality-of-life assessment
|Study Design:||Allocation: Randomized
Primary Purpose: Supportive Care
|Official Title:||A Randomized, Double-Blind, Placebo-Controlled, Multicenter Trial to Evaluate the Safety and Efficacy of Zoledronate (4 and 8 mg) Administered Intravenously as an Adjuvant to Anticancer Therapy to Patients With Any Cancer With Bone Metastases Other Than Breast Cancer, Multiple Myeloma or Prostate Cancer|
|Study Start Date:||August 1998|
|Study Completion Date:||January 2001|
|Primary Completion Date:||January 2001 (Final data collection date for primary outcome measure)|
OBJECTIVES: I. Assess the safety and efficacy of zoledronate in patients with any solid tumor cancer with bone metastases other than breast or prostate cancer. II. Assess the efficacy of zoledronate in preventing skeletal-related events including tumor induced hypercalcemia (TIH), time to first occurrence of skeletal-related event or TIH, skeletal morbidity rate, time to progression of bone metastases, overall survival, and time to overall disease progression in these patients. III. Assess the quality of life and pain in these patients on these regimens.
OUTLINE: This is a randomized, double blind, placebo controlled, multicenter study. Patients are stratified into two groups: patients with lung cancer and patients with all other solid tumor cancers. Patients are randomly assigned to receive 1 of the following treatments: Arm I: Patients receive intravenous zoledronate over 5 minutes every 3 weeks for 9 months. Arm II: Patients receive intravenous zoledronate at a higher dose over 5 minutes every 3 weeks for 9 months. Arm III: Patients receive intravenous placebo over 5 minutes every 3 weeks for 9 months. All patients receive oral calcium daily, and an oral multivitamin supplement. Quality of life is assessed prior to therapy, then at months 3, 6, and 9. Patients are followed every 6 months for survival.
PROJECTED ACCRUAL: A total of 600 patients will be accrued for this study within 12 months.
