About this study

Official title: A Phase 1 Study to Evaluate the Safety, Tolerability, and Immunogenicity of EGFR (Vectibix® Sequence)-Targeted EnGeneIC Dream Vectors Containing Doxorubicin (EGFR(V)-EDV-Dox) in Subjects With Recurrent Glioblastoma Multiforme (GBM)

The purpose of the Cerebral EDV study is to determine the safety and tolerability of EGFR(V)-EDV-Dox in order to establish the best dose level to be used in future studies. The study will also examine the body's immune response to EGFR(V)-EDV-Dox and assess if it is effective in the treatment of patients with recurrent glioblastoma multiforme (GBM).

Read the detailed description

This is an open-label, Phase 1, dose exploration and preliminary immunogenicity study of single agent EGFR(V)-EDV-Dox in subjects with recurrent glioblastoma (GBM). Eligible subjects enrolled in the study will receive EGFR(V)-EDV-Dox administered weekly for 7 weeks via IV 20 minute infusion, followed by radiological evaluation at week 8 (1 Cycle). Subjects may continue to receive subsequent cycles of EGFR(V)-EDV-Dox unless the subject becomes intolerant to investigational product (IP), withdraw consent or the individual is no longer receiving clinical benefit (factors taken in to consideration will be disease progression radiologically or clinically, and clinical benefits to quality of life). Tumour assessment will be repeated after each 7 week cycle (week 8).

The study will take place in two parts, Part 1 (Dose Exploration) and Part 2 (Dose Expansion).

Part 1 - Dose Exploration will assess the safety and tolerability of multiple doses of drug at two dose levels (5 x 10^9 and 8 x 10^9) and will enroll prior to Part 2. Three subjects will be recruited per dose level. Enrollment will begin with the 5 x 10^9 dose level, and the decision to enroll to the 8 x 10^9 dose level will follow a comprehensive safety evaluation and a standard 3 + 3 dose escalation study design.

Part 2 - Dose Expansion will be conducted pending safety results of Part 1 to provide guidance regarding the recommended phase 2 dose (RP2D). Subjects will be treated and assessed as outlined in Part 1 above. If 0 out of 3 subjects, or 1 out of 6 subjects, experience dose limiting toxicities (DLTs) at the 5 x 10^9 dose level in Part 1, additional subjects to a total of 10 will be recruited to this dose level in Part 2. Similarly, if 0 out of 3 subjects, or 1 out of 6 subjects, experience DLTs at the 8 x 10^9 dose level in Part 1, additional subjects to a total of 10 will be recruited to this dose level in Part 2. If both dose levels are tolerated, a total of 10 subjects per dose level will be enrolled.

A safety follow-up visit must be performed 30 (+5) days after the last dose of drug for all subjects.All subjects who discontinue investigational product and who have not withdrawn full consent to participate in the study will continue in the long term follow-up phase. Long term follow-up will continue approximately every 1 month for 12 months, from the 30 (+5) day follow-up visit, then approximately every 2-3 months for the extent of subject survival.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EGFR(V)-EDV-DoxDrug

    Also called EnGeneIC Dream Vector™, EnGeneIC Delivery Vehicle™

    EGFR(V)-EDV-Dox using EnGeneIC EDV™ technology is a bacterially derived minicell which packages a toxic payload, Doxorubicin, into a 400 nm particle which targets specific cancer cells using bispecific antibodies (BsAb). BsAb-targeted, payload-packaged EDV nanocells only exit the leaky blood vessels associated with tumors and enter into the tumor microenvironment. The BsAb binds to the tumor cell-surface receptor, where the EDV is taken up, broken down within the cancer cell and releases the Doxorubicin. The residual EDVs that do not make it into the tumor microenvironment, are engulfed by cells of the immune system and since the EDVs are derived from bacteria, they carry potent immuno-stimulating components which appear to bypass the immuno-suppression caused by the tumor.

Study groupRoleWhat they receive
EGFR(V)-EDV-DoxExperimentalEGFR(V)-EDV-Dox administered via 20 minute intravenous infusion once a week for seven weeks (1 Cycle). Subjects will receive one of two dose levels: 5 x 10^9 or 8 x 10^9. All subjects will undergo an adapted dose escalation regime in the first cycle of treatment. For subsequent cycles all doses will be administered at full strength (5x10^9 or 8x10^9 EGFR(V)-EDV-Dox). Subjects may receive further cycles of treatment if the tumor remains stable or is responding, and/or they are deriving clinical benefit from the therapy and are tolerating treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety outcome measures

    Recording of adverse Events (AE's) and clinically significant changes in vital signs, physical and neurological examinations, cardiac tests, radiological imaging inc. CT scan (Day 27/28) and clinical laboratory tests.

    Measured: Safety measures will be conducted from Study Day 1 as per study schedule to safety follow-up visit 30 (+5 days) post last dose.

Secondary outcomes (3)
  1. Efficacy outcome measure

    Disease response will be measured by Magnetic Resonance Imaging (MRI) using Response Assessment in Neuro-Oncology (RANO).

    Measured: Screening, then post cycle (Days 50-56)

  2. Identification of a recommended Phase 2 dose (RP2D) of EGFR(V)-EDV-Dox in subjects with recurrent GBM

    Review of safety data for dose limiting toxicity (DLT) evaluable subjects.

    Measured: DLT evaluable subjects are those who experience a DLT assessed within the first treatment cycle of Part 1 i.e.including up to 7 days after the final dose, days 1-50 of treatment.

  3. Overall survival outcome measure

    Overall survival is defined as time from the date of first administration of EGFR(V)-EDV-Dox to the date of death, regardless of cause

    Measured: The number of days from the date of first administration of EGFR(V)-EDV-Dox to the date of death, regardless of cause up to 60 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing EGFR(V)-EDV-Dox in people with Glioblastoma and Astrocytoma, Grade IV, run by Engeneic Pty Limited at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 32 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety outcome measures (time frame: Safety measures will be conducted from Study Day 1 as per study schedule to safety follow-up visit 30 (+5 days) post last dose.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jun 2025.
