Convection-Enhanced Delivery (CED) of MDNA55 in Adults With Recurrent or Progressive Glioblastoma

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02858895
Recruitment Status : Completed
First Posted : August 8, 2016
Last Update Posted : January 15, 2021
Information provided by (Responsible Party):
Medicenna Therapeutics, Inc.

Brief Summary:
This is a single-arm, open-label, multicenter study in approximately 52 adults with primary (de novo) GB that has recurred or progressed (first or second recurrence, including this recurrence) after treatment(s) including surgery and radiotherapy with or without chemotherapy and following discontinuation of any previous standard or investigational lines of therapy.

Condition or disease Intervention/treatment Phase
Glioblastoma Grade IV Astrocytoma Glioblastoma Multiforme Grade IV Glioma Drug: MDNA55 Phase 2

Detailed Description:

The study drug, MDNA55, is a fusion protein comprising a genetically engineered Interleukin-4 (IL-4) linked to a modified version of the Pseudomonas aeruginosa exotoxin A (PE). MDNA55 binds to the IL-4 receptor (IL4R), over-expressed by cancer cells and non-malignant immunosuppressive cells of the tumor microenvironment (TME), and delivers a potent cell-killing agent, PE.

The study will be conducted at up to 10 clinical sites following institutional review board approval and completed informed consent.

Subjects that meet the study eligibility criteria will undergo surgery associated with study drug administration. MDNA55 will be administered locally by convection-enhanced delivery (CED).

Post-treatment follow-up assessment of safety and efficacy will be performed monthly for the first 6 months and bimonthly thereafter for approximately 1 year after study drug administrations. Subjects will continued to be followed for survival and post-study treatment(s) of GB after study completion or withdrawal.

Primary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: 12 months ]
    OS, time from treatment until death

Secondary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: 12 months ]
    ORR, determined by independent central review (per RANO-based criteria)

  2. Progression Free Survival (PFS) [ Time Frame: 12 months ]
    PFS, time from treatment until disease progression (per RANO-based criteria) or death

Other Outcome Measures:
  1. Serious adverse events (SAEs) [ Time Frame: 12 months ]
    Incidence of SAEs

  2. Treatment emergent adverse events (AEs) [ Time Frame: 12 months ]
    Incidence of Treatment-Emergent AEs

  3. Pharmacokinetics (PK) of MDNA55 [ Time Frame: 14 days ]
    Blood samples will be collected to determine levels of MDNA55

  4. Anti-MDNA55 antibody [ Time Frame: 12 months ]
    Blood samples will be collected to determine anti-drug antibody titers
