Retreatment with Rhenium LiposomeEXPERIMENTALEach participant will receive a single administration of 186RNL. The proposed dose is up to 8.8 mL as a single administration with an administered dose of 22.3 mCi.
Interventions
NameTypeDescription
Retreatment Rhenium LiposomeDRUGAt the time of stereotactic biopsy a catheter will be placed within the tumor using stereotactic guidance. Once the patient has adequately recovered from the procedure as determined by the neurosurgeon, 186RNL will be infused through the CED catheter at the predetermined dose. Spectroscopic imaging will then be obtained at predefined time points to visualize the distribution of the 186RNL as well as calculated the actual dose retained within the tumor. Patients will be monitored longitudinally for evidence of toxicity and response by MRI.
