About this study

Official title: A Phase I Study of WT1 Peptides to Induce Anti-Leukemia Immune Responses Following Autologous or Allogeneic Transplantation for AML, CmML, ALL, MDS, and B Cell Malignancies

The purpose of this study is to determine the safety and effectiveness of administering Wilms tumor gene 1 (WT1) cancer peptides. Cancer peptides are short pieces of protein that are made in a laboratory to be like the peptides that can be found in cancer. These peptides are intended to be given as a "vaccine" to activate the immune cells in a person to attack his/her cancer. These peptides are mixed with an oily substance called Montanide ISA-51 and a white cell growth factor called Granulocyte-macrophage colony-stimulating factor (GM-CSF) which may help make the immune response stronger.

Read the detailed description

Two subgroups with 2 dose cohorts of up to 6 patients each will be enrolled in this exploratory study in order to attempt to obtain immunologic and clinical data on patients with a variety of hematologic malignancies and amongst those in remission and early relapse. The 2 subgroups of patients will be treated with different schemas depending upon whether they are undergoing or have undergone autologous or allogeneic stem cell transplantation.

For the autologous transplant patients: Immune monitoring will require 90ml peripheral blood before the first immunization, 3-5 ml from the leukapheresis product, 40-90ml peripheral blood before the 4th immunization immunizations, after the last immunization (week 6-8), and at the discretion of the immune monitoring lab, every two months if immunizations are continued.

For the allogeneic transplant patients: Immune monitoring will require 90ml peripheral blood before the first immunization, 40-90ml peripheral blood before the 4th immunization immunizations, after the last immunization (week 6-8), and at the discretion of the immune monitoring lab, every two months if immunizations are continued.

Subjects will be monitored with blood pressure, temperature, and pulse, pre-injection, at 15 and 30 minutes after injection, prior to being allowed to leave the clinic. Diphenhydramine 50 mg, solumedrol 100 mg, and epinephrine 1:1000 (1 mL) must be available bedside (or a clinic code cart must be available). If hypotension (SBP <90mmHg for patients with baseline SBP > 110mmHg or > 20 mmHg decrease for those with baseline SBP< 110 mmHg), urticaria or orofacial or laryngeal edema or bronchospasm occurs, an IV line will be placed and the diphenhydramine 50 mg, solumedrol 100 mg, and epinephrine 1:1000 sq are recommended. In this event, patients will be transported emergently to the emergency room if stabilized or the code team will be contacted if patients continue to have progression of symptoms or worsening hypotension. For fever>101.5, acetaminophen 650 mg may be given orally.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing WT1 derived peptides in people with Acute Myelogenous Leukemia (AML) and Chronic Myelogenous Leukemia (CML), run by Michael Morse, MD at 1 site 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 25 inclusion and 5 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: stopped early, as of the sponsor's last update on 10 Dec 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 was stopped early (reason given: low accrual). Results are not available in the source record.

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 and Feasibility (time frame: 2 years). 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 10 Dec 2013.
