Injectable IsoPet® comprises of an insoluble yttrium-90 (⁹⁰Y) phosphate
radiation source mixed within an injectable, thermally reversible,
temperature-sensitive polymer solution. After injection, the mixture gels within
tumor extracellular spaces as it warms to body temperature--to ensure that
the ⁹⁰Y micro-particles remain in tumors.
Yttrium-90 (⁹⁰Y) is a high-energy beta emitter with a physical half-life of
64 hours (2.7 days); Yttrium-90 (⁹⁰Y) is the active radioactive source in
several FDA-approved medical applications in cancer treatment.
Single-dose treatment of tumors (300 to 400 Gy)
placed by multiple needle injections using
standard 1 cc syringes and 25-gauge needles
High therapeutic index with effective tumor
ablation, even in radiation-resistant disease
Out-patient procedure with minimal side-effects
Injection materials remain in the tumor and
radioactivity is not excreted
PRODUCT FEATURES:
Gel is naturally resorbed and only 5% of the
radioactivity remains ten days after treatment
Pure-beta emission means negligible radiation
dose to health care workers and pet owners
Minimal radioactive waste (swabs, needles, and
syringes) may be held for decay (40 days) and
then disposed of as standard trash
Special shielding not required
