First Time in Human Study

Y90 radioembolization with Eye90 microspheres

Eye90 Microspheres® Clinical Development

Our lead development product, Eye90 microspheres, is being studied for the first time in humans.

Conventional Y90 radioembolization has been used to treat over 100,000 patients with liver tumors since 2002. Eye90 microspheres has the potential to significantly improve the clinical success of Y90 radioembolization, leveraging state-of-the-art tumor imaging science and advanced microsphere engineering technologies.

This study is assessing Eye90 microspheres for the treatment of patients with unresectable hepatocellular cancer (HCC) or metastatic colorectal cancer (mCRC) in collaboration with Auckland Hospital Research Unit, New Zealand.

Study Design and Conduct

Study Description

The purpose of this study is to evaluate the safety of treatment with Eye90 microspheres® in patients with unresectable Hepatocellular Carcinoma (HCC) and metastatic Colorectal Cancer (mCRC). Both cause tumors that have an abnormally large number of blood vessels attached to them. Eye90 microspheres is internal radiation brachytherapy for the treatment of liver tumors that uses microspheres, tiny glass beads smaller in diameter than human hair, to provide radiation.

The microspheres contain Yttrium-90 (Y90) as the radiation source, which is used to kill cancer cells and shrink tumors. The microspheres are also radiopaque, which means that they can be seen during imaging procedures. The visibility of the microspheres allows the doctor to confirm the microspheres have been delivered precisely to the tumor; this may help to improve the outcome of treatment.

Study Design

Investigation of Safety and Effectiveness of Eye90 Microspheres® in the Treatment of Unresectable Hepatocellular Carcinoma (HCC) and Metastatic Colorectal Cancer (mCRC)

Patients in this single-center, open-label study will receive a single Eye90 microspheres radioembolization treatment with follow-up visits for one year to assess safety, effectiveness, and quality of life measures.

The study will be conducted at Auckland Hospital, New Zealand
