Alternate Title

Radiolabeled Octreotide in Treating Children With Advanced or Refractory Solid Tumors

Basic Trial Information

Objectives

1. Determine the maximum tolerated dose of yttrium Y 90-DOTA-tyr3-octreotide in children with advanced or refractory somatostatin receptor-positive tumors.
2. Determine the short-term and long-term safety and the serious adverse-event profiles of this drug in these patients.
3. Determine any potential antitumor effect of this drug in these patients.
4. Correlate level of somatostatin receptor type 2 expression with response in patients treated with this drug.

Entry Criteria

Disease Characteristics:

• Histologically or cytologically confirmed malignant neoplasm
  • Not amenable to standard therapy or has failed existing first- and second-line therapies
• Tumor positive for somatostatin receptors by OctreoScan within the past 4 weeks
• At least 1 measurable lesion

• No prior allergic reactions to compounds of similar chemical or biologic composition to yttrium Y 90-DOTA-tyr3-octreotide
• No ongoing or active infection
• Not pregnant or nursing
• Negative pregnancy test
• Fertile patients must use effective contraception during and for 6 months after study participation

Expected Enrollment

Approximately 25-35 patients will be accrued for this study.

Outline

This is a dose-escalation study.

Patients receive yttrium Y 90-DOTA-tyr3-octreotide IV over 5-10 minutes on day 1. Treatment repeats every 6 weeks for up to 3 courses in the absence of unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of yttrium Y 90-DOTA-tyr3-octreotide until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity.

Patients are followed weekly after each treatment course, 6 weeks after the last course, and then every 6 months thereafter for life.
