About this study

Official title: A Phase II Study of Active Immunotherapy With GRNVAC1, Autologous Mature Dendritic Cells Transfected With mRNA Encoding Human Telomerase Reverse Transcriptase, in Patients With Acute Myelogenous Leukemia in Complete Clinical Remission

This is a phase II study to evaluate the safety, feasibility and efficacy of immunotherapy with GRNVAC1 in patients with AML.

Read the detailed description

This is a multicenter, open-label evaluation of feasibility, safety and immunotherapy in patients with AML in complete clinical remission. Patients will undergo leukapheresis prior to or shortly after completing consolidation chemotherapy. Dendritic cells will be transfected with the messenger RNA encoding human telomerase reverse transcriptase (hTERT) and a portion of the lysosome-associated membrane protein LAMP-1 (LAMP), matured, aliquoted, and cryopreserved. The final autologous vaccine product is referred to as GRNVAC1. Patients will be vaccinated with weekly for 6 weeks,will "rest" for 4 weeks, then will receive 6 boost injections, each administered every other week for 12 weeks. Patients will be followed every 4 weeks until Week 54, then every 3 months for 1 year, then every 6 months up to approximately 5 years from the first vaccination or until relapse/progression.

GRNVAC1ExperimentalAutologous dendritic cell vaccine
Receives: Biological: GRNVAC1

What is being measured

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

  1. Feasibility will be assessed by examining whether enough cells are collected during leukapheresis, whether enough vaccine is manufactured for at least 2 injections, and whether the patient is still in remission when the vaccine is released.

    Measured: 1 year

Secondary outcomes (1)
  1. Immunological response, defined as the proportion of patients with a positive induction of hTERT-specific T cells to twice the pre-vaccination level, the proportion of patients with DTH, and event-free survival.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing GRNVAC1 in people with Acute Myelogenous Leukemia, run by Asterias Biotherapeutics, Inc. at 6 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 4 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: finished, as of the sponsor's last update on 9 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 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?

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?

Feasibility will be assessed by examining whether enough cells are collected during leukapheresis, whether enough vaccine is manufactured for at least 2 injections, and whether the patient is still in remission when the vaccine is released. (time frame: 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 9 Jul 2019.
