About this study

Official title: BrUOG 263: PSMA ADC for Recurrent Glioblastoma Multiforme (GBM): A Phase II Brown University Oncology Research Group Study

The purpose of this study is to evaluate the effectiveness of Prostate Specific Membrane Antigen (PSMA ADC), as well as its safety and side effects for patients with advanced brain tumors. This study will also study how your body metabolizes (breaks down) PSMA ADC.

Read the detailed description

PSMA expression has been demonstrated in the tumor neovasculature of Glioblastoma Multiforme (GBM) by immunohistochemical staining. Strong reactivity to the antibody component of PSMA ADC was observed in the endothelial cells of new tumor blood vessels in GBM. Since the endothelial cells are located on the luminal surface of blood vessels, PSMA ADC does not need to cross the blood brain barrier to reach its target. Following binding and internalization of PSMA ADC, the cytotoxic component of PSMA ADC will be released and destroy the neovasculature that supports tumor growth. Therefore, PSMA ADC may be an active treatment for GBM.

Bevacizumab, an inhibitor of angiogenesis, has been shown to be effective in improving progression-free survival as a single agent. Thus PSMA ADC, which targets tumor angiogenesis by a mechanism different from that of bevacizumab, may be a novel therapeutic modality for GBM.

A phase 2 study of PSMA ADC is proposed for patients with GBM that have progressed after standard treatment that includes radiation, temozolomide and bevacizumab. A phase 1 study of PSMA ADC in prostate cancer is ongoing and a phase 2 dose level of 2.5 mg/kg IV every 3 weeks has been defined. Treatment after bevacizumab failure for patients with GBM is a major unmet medical need. If activity were demonstrated in this trial, a definitive randomized study would be proposed.

What is being measured

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

  1. Response Rate (Progression) for Patients With Glioblastoma That Have Progressed After Prior Treatment That Has Included Radiation, Temozolomide and Bevacizumab.

    The response assessment in neuro-oncology (RANO) will be used to define radiographic response.

    (PD): A >25% increase in tumor area (product of two diameters) OR appearance of a new lesion/site, OR clear clinical worsening or failure to return for evaluation due to death or deteriorating condition (unless clearly unrelated to this cancer).

    Measured: 3 months until progression, potentially up to 1 year

Secondary outcomes (1)
  1. Number of Patients Who Experienced Toxicities (Adverse Events) Who Received PSMA ADC for Recurrent Glioblastoma.

    Please note that toxicities outlined may not all be related to the treatment regimen.

    Measured: at least every 3 weeks for a maximum of 30 post coming off drug, approximately 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing PSMA ADC in people with GBM and Glioblastoma Multiforme, run by Heinrich Elinzano, MD 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 22 inclusion and 11 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 23 Nov 2021. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Jun 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Response Rate (Progression) for Patients With Glioblastoma That Have Progressed After Prior Treatment That Has Included Radiation, Temozolomide and Bevacizumab. (time frame: 3 months until progression, potentially up to 1 year). 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 23 Nov 2021.
