Radiolabeled Octreotide in Treating Children With Advanced or Refractory Solid Tumors
RATIONALE: Radiolabeled octreotide can locate tumor cells and deliver radioactive tumor-killing substances to them without harming normal cells.
PURPOSE: This phase I trial is to study the safety and effectiveness of radiolabeled octreotide in treating children who have advanced or refractory solid tumors.
Brain and Central Nervous System Tumors
Gastrointestinal Carcinoid Tumor
Islet Cell Tumor
Unspecified Childhood Solid Tumor, Protocol Specific

|Official Title:||A Phase I, Open Label, Maximum Tolerated Dose-Finding Study to Evaluate the Safety and Tolerability of 90Y-DOTA-tyr3-Octreotide Administered by Intravenous Infusion to Children With Refractory Somatostatin-Receptor Positive Tumors|
- Establish the three-cycle maximum-tolerated dose of 90Y-DOTA-tyr3-Octreotide [ Time Frame: 6 weeks per cycle ]Establish the three-cycle maximum-tolerated dose of 90Y-DOTA-tyr3-Octreotide administered by intravenous infusion to children with refractory somatostatin-receptor positive tumors based upon the 6 week/cycle dose-limiting-toxicity profile.
- Evaluate the short term and long term safety (mild/moderate/severe/life-threatening adverse events, premature discontinuations and serious adverse events) [ Time Frame: short term (6 weeks/cycle); long term (4-6 mos./cycle) ]2. Evaluate the short-term (6 weeks/cycle) and long term (4-6 months) safety (mild/moderate/severe/life-threatening adverse events, premature discontinuations and serious adverse events) serious adverse event profile of three-cycles of 90Y-DOTA-tyr3-Octreotide administered by intravenous infusion to children with refractory somatostatin-receptor positive tumors.

Dose escalation will proceed so that the single-cycle and three-cycle maximum tolerated doses of 90Y-DOTA-tyr3-Octreotide can be determined. The initial dose of 90Y-DOTA-tyr3-Octreotide to be administered is 30 mCi/m2 in each of three cycles. Dose escalation will proceed in 10 mCi/m2 intervals and will be permitted for the next cohort of subjects pending completion of Cycle 3 by 2 members of the previous cohort with no DLTs. A DLT is defined as a Grade 3 renal toxicity, Grade 4 bone marrow toxicity, or any other Grade 3 toxicity whether or not related to study drug and regardless of duration. Lymphopenia will not be used to define a DLT.
- Determine the maximum tolerated dose of yttrium Y 90-DOTA-tyr3-octreotide in children with advanced or refractory somatostatin receptor-positive tumors.
- Determine the short-term and long-term safety and the serious adverse-event profiles of this drug in these patients.
- Determine any potential antitumor effect of this drug in these patients.
- Correlate level of somatostatin receptor type 2 expression with response in patients treated with this drug.
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.
PROJECTED ACCRUAL: Approximately 25-35 patients will be accrued for this study.
