Eligibility

Inclusion

  • Performance status as determined by Karnofsky ≥ 60 or Lansky Play Scale ≥ 60% at the time of study drug administration.
  • The target lesion is one that either has never received external beam radiation or has been previously irradiated and has since demonstrated progression. Any local irradiation of the target lesion or any non-target lesions via external beam, conformal or stereotactic radiation treatments must have occurred more than 4 weeks prior to study drug administration. Any full cranial-spinal radiation, whether or not a target lesion is included in the field, must have occurred more than 3 months prior to study drug administration.
  • The effects of 90Y-DOTA-tyr3-Octreotide on the developing human fetus are unknown. For this reason and because Class C agents are known to be teratogenic, women and men of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
  • Platelets \>90,000/mm3
  • Disease not amenable to standard treatment (nonresectable or disease present after one or more surgeries and/or Sandostatin treatment) or subject has failed existing first line chemotherapy, biologic therapy, targeted agent therapy or radiation therapy.
  • A pathologically confirmed (histology or cytology) malignant neoplasm with at least one target lesion that is confirmed by conventional imaging and is determined to express somatostatin receptors by 68Ga-DOTATOC (TATE) PET within 6 months prior to treatment with 90Y-DOTATOC.
  • absolute neutrophil count \>1000/mm3

Exclusion

  • Surgery within 4 weeks of study drug administration.
  • Any subject for whom, in the opinion of their physician, a 12-hour discontinuation of somatostatin analogue therapy represents a health risk. Also subjects who have received SandostatinLAR in the past 28 days or long-acting lanreotide within the past 8 weeks are excluded. Subjects may be maintained on short acting octreotide during the time from last injection of long-acting somatostatin analogue until 12 hrs prior to injection of study drug. Known antibodies to Octreotide, Lanreotide, or DOTATOC or history of allergic reactions attributed to compounds of similar chemical or biologic composition to 90Y-DOTATOC.
  • Another investigational drug within 4 weeks of study drug administration.
  • External beam radiation to both kidneys (scatter doses of \<500 cGy to a single kidney or radiation to \< 50% of a single kidney is acceptable).
  • Another significant medical, psychiatric, or surgical condition which is currently uncontrolled by treatment and which would likely affect the subject's ability to complete this protocol.
  • Pregnant women are excluded from this study because 90Y-DOTATOC is a Class C agent with potential teratogenic or abortifacient effects.
  • Prior PRRT with 90Y-DOTATOC (TATE) or 177Lu-DOTATOC (TATE) or 131I-MIBG therapy for this malignancy.
