About this study

Official title: Randomized Phase 2b Study of Safety And Efficacy Of TVI-Brain-1 Combined With Conformal Radiotherapy And Temozolomide Vs Standard Therapy In Newly Diagnosed MGMT Negative Glioblastoma Multiforme (GBM)

This randomized study is designed to compare the combination of TVI-Brain-1 immunotherapy and standard therapy compared to standard therapy alone as a treatment for newly diagnosed MGMT unmethylated glioblastoma patients. The patients' own cancer cells collected after surgery are combined into a vaccine to produce an immune response that significantly increases the number of cancer neoantigen-specific effector T cell precursors in the patient's body. These cancer neoantigen-specific T cells are harvested from the blood, subsequently stimulated and expanded, and infused back into the patient.

Read the detailed description

This randomized study is designed to compare the combination of TVI-Brain-1 immunotherapy and standard therapy compared to standard therapy alone as a treatment for newly diagnosed MGMT unmethylated glioblastoma patients. The general procedures include the collection and testing of cancer tissue samples after surgery and chemoradiation therapy (radiation and temozolomide). For the patients randomized into the investigational study treatment group, they will also receive two vaccinations created from their own cancer cells, undergo leukapheresis to collect immune T-cells from their blood, and transfer of those activated effector T-cells after chemoradiation therapy. All patients are followed with MRIs at follow-up visits.

Being tested
TVI-Brain-1, Standard of Care, Radiotherapy, Temozolomide

What participants receive

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

  • TVI-Brain-1Biological

    Attenuated autologous cancer cells and activated autologous blood-derived t cells

  • Standard of CareProcedure or surgery

    Surgery for tumor removal or debulking to minimize tumor burden

  • RadiotherapyRadiation

    Conformal radiotherapy consists of fractionated focal irradiation at a dose of 2 Gy per fraction given once daily five days per week (Monday through Friday) over a period of six weeks.

  • TemozolomideDrug

    Also called Chemotherapy

    All Subjects receive 75 mg/m2 of temozolomide daily beginning on the first day of radiotherapy and continuing until the completion of radiotherapy. Standard of care Subjects will also receive adjuvant temozolomide .

Study groups in NCT05685004
Study groupRoleWhat they receive
Standard of CareActive comparatorSubjects will have standard surgery which will be followed approximately 5 weeks later by combined radiotherapy and chemotherapy consisting of temozolomide 75 mg/m2 dosed once daily beginning on the first day of radiotherapy and continuing until the final day of radiotherapy. Subjects will receive adjuvant temozolomide, and proceed with post therapy surveillance.
Receives: Procedure: Standard of Care; Radiation: Radiotherapy; Drug: Temozolomide
Interventional TVI-Brain-1 Autologous Vaccine and activated autologous blood-derived t cellsExperimentalTVI-Brain-1 immunotherapy is integrated with radiation and temozolomide in the test group in the following manner: 1) Subjects undergo surgical resection of their cancer and are tapered off steroids. 2) Subjects receive the first vaccination of TVI-Brain-1 as soon as the laboratory prepared vaccine is available for use (approximately 7 - 14 days following surgery). 3) Subjects receive a second vaccination 7-10 days later. 4) Subjects are leukapheresed to obtain immune T cells for ex vivo-activation. 5) Subjects' T cells are stored frozen until after chemoradiotherapy is completed. 6) Following chemoradiotherapy Subjects are infused with activated effector T cells followed by a 10-day course of low-dose interleukin 2 (IL-2). 7) Subjects then proceed with post therapy surveillance.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing TVI-Brain-1, Radiotherapy and Temozolomide in people with Glioblastoma Multiforme of Brain, run by TVAX Biomedical at 8 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 11 inclusion and 6 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: under way, not looking for participants, as of the sponsor's last update on 29 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Survival (time frame: From date of randomization until the date of death from any cause assessed up to 24 months after randomization.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05685004, which also lists 5 linked publications.

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 29 Sep 2026.
