Precision, convection enhanced drug delivery under real time MRI guidance combined with this novel agent hold great promise for patients with this aggressive form of brain cancer

IRVINE, Calif., Dec. 19, 2016 (GLOBE NEWSWIRE) -- MRI Interventions, Inc. (OTCQB:MRIC) today announced that its ClearPoint® Neuro Navigation System will be utilized in a Phase 2 Trial for recurrent glioblastoma  with Medicenna Therapeutics’ lead clinical candidate, MDNA55, a novel cancer immunotherapy.  Based on Medicenna’s platform of Empowered Cytokines, MDNA55 is a targeted form of immunotherapy designed to purge tumor cells and adjacent immunosuppressive cells in the tumor microenvironment that over-express the interleukin-4 receptor (IL4R), which is common in a majority of patients with recurrent glioblastoma. By directly eliminating tumor cells and boosting a therapeutic immune response in these patients, MDNA55 provides a two-pronged approach to treat brain cancer. The use of precision, MRI image-guided, Convection Enhanced Delivery (CED) of the MDNA55 is anticipated to target the tumor and its microenvironment while dramatically reducing systemic side effects.

 “We are pleased to be a part of this landmark trial using immunotherapy to treat patients with this aggressive form of brain cancer.  The ClearPoint Neuro Navigation System is currently being utilized in seven clinical and pre-clinical trials, in which precision delivery of drugs or agents deep in the brain is critical to a therapeutic response,” said Wendelin Maners, Vice President of Marketing.

Study Design

The multi-center, single-arm, open-label, Phase 2 investigation of MDNA55 (ClinicalTrials.gov identifier: NCT02226965) will enroll approximately 43 adult patients with glioblastoma who have progressed or recurred following first line therapy.  Clinicians will be able to utilize real-time, MRI guided navigation with the ClearPoint System to place the catheter to target and administer a  single intra-tumoral infusion of MDNA55 using convection enhanced delivery (CED), a minimally invasive technique used to by-pass the blood brain barrier.

The primary endpoint is overall response rate (ORR), assessed by magnetic resonance imaging using the Revised Assessment in Neuro-Oncology (RANO) criteria.  Secondary outcome measures include progression-free survival, overall survival, and exploratory predictors of outcome assessed by IL-4R expression in archived tumor biopsies.
