Determination of a Safe Dose of Optison in Pediatric Patients With Solid Tumors
St. Jude Children's Research Hospital is studying ways to make ultrasound images clearer - to be able to see blood vessels, body structures, and tumors better. Ultrasound uses sound waves to create pictures, allowing doctors and other medical professionals to "see" inside the body.
Researchers are studying a contrast agent (like a dye) called Optison™. St. Jude Children's Research Hospital researchers want to learn the best and safest dose of this ultrasound "dye."
|Study Design:||Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
|Official Title:||Determination of Optimal Dose and Safety Profile of Optison Ultrasound Contrast Agent in Pediatric Solid Tumor Patients|
- To learn the best dose of Optison™ ultrasound contrast agent that can be safely given to children with abdominal or pelvic tumors. [ Time Frame: Unknown-study temporarily closed. ]
- To learn the effects (good and bad) of using Optison during ultrasound. [ Time Frame: Unknown-study temporarily closed. ]
- To learn if using Optison™ during ultrasound can show the size and location of a tumor, how the tumor is responding to chemotherapy, and whether it has moved into surrounding tissue. [ Time Frame: Unknown-study temporarily closed. ]

|Primary Completion Date:||August 2004 (Final data collection date for primary outcome measure)|
Based on recommendation by the FDA, we began with a dose of 0.125ml/m^2 and escalated at 0.15 ml/m^2 increments, to 0.275 ml/m^2 and 0.425ml/m^2 and 0.500ml/m^2. We will now continue to escalate the dose of Optison at 0.300ml/m^2 increments to a maximum single dose of 4ml or a total cumulative dose of 8.7 ml as recommended by the manufacturer.
