Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. At least 18 years of age at time of screening.
  2. Ability to understand the purposes and risks of the study and has signed a written informed consent document approved by the site-specific IRB.
  3. Patient must present with biopsy and histology proven glioma following initial treatment with 186RNL. The type and grade of glioma to follow the 2021 WHO Classification of Tumors of the Central Nervous System, allowing Grade III and IV gliomas.
  4. At least 90 days from prior dose of 186RNL at time of screening.
  5. Patients who receive treatment with antiepileptic medications must have a two-week history of stable dose of antiepileptic without seizures prior to dosing.
  6. Patients with corticosteroid requirements to control cerebral edema must be maintained at a stable or decreasing dose for a minimum of two weeks without progression of clinical symptoms.
  7. A volume of enhancing tumor which falls within the treatment field volume being evaluated in the respective cohort (see 4.1 Design).
  8. ECOG performance status of 0 to 2; ECOG 3 acceptable if Principal Investigator and treating physician confirm in patient's interest in study/re-treatment.
  9. Life expectancy of at least 2 months
  10. Acceptable liver function: Bilirubin ≤ 1.5 times upper limit of normal and AST (SGOT) and ALT (SGPT) ≤ 3.0 times upper limit of normal (ULN)

  12. Acceptable hematologic status (without hematologic support): ANC ≥1000 cells/uL, Platelet count ≥100,000/uL if no bleeding, Hemoglobin ≥7.0 g/dL. Given the absence of hematological toxicity in the ongoing recurrent glioblastoma trial (#12-02) and the need for CED catheter placement, the Investigator and Sub-investigator (neurosurgeon) placing the CED catheter may determine that it is in the patient's best interest and acceptably safe to proceed with this criteria with hematological support or, if no bleeding, Platelet count ≥75,000/uL without support, ANC 1000 cells/uL and Hemoglobin ≥7.0 g/dL

    5. Study Description

    Brief Summary
    This is an open-label, multicenter, Phase 1 study to establish the safety and efficacy/tolerability of a single dose of 186RNL by the intraventricular route (via intraventricular catheter) for recurrence glioma in patients who received a prior treatment of 186RNL.
    Detailed Description
    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.

    Retreatment Rhenium Liposome
    Other Intervention Name(s)
    Rhenium-186 NanoLiposome
    Intervention Description
    At 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.
