Safety & Efficacy/Tolerability of Rhenium-186 NanoLiposomes (186RNL) for Patients Who Received a Prior 186RNL Treatment

This Phase I clinical study evaluates a single dose of 186RNL (radionuclide clinical study drug) administered through a convection enhanced delivery catheter (CED catheter) in participants who have already received a prior treatment of 186RNL. The clinical study treatment consists of a single administered dose of 186RNL per participant. The proposed dose is up to 8.8 mL as a single administration with an administered dose of 22.3 mCi. An estimated number of participants to be enrolled in the study is approximately 40. The clinical study treatment will be administered, following CED placement, by the clinical study physician. Post-treatment evaluations will be done at Days 3, 7, 14, 28, and every subsequent 28-day interval thereafter until disease progression is confirmed and all treatment related toxicities are resolved. The minimum assessment period for toxicities is 12 weeks. The U.S. Food and Drug Administration (FDA) has not approved 186RNL for this specific disease.
