About this study

Official title: MT2005-13R - Phase I Open Label, Single Arm, Dose Escalation Trial to Evaluate the Biodistribution and Safety of AHN-12 in Patients With Advanced Leukemia

RATIONALE: Monoclonal antibodies can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Radioactive monoclonal antibodies, such as yttrium Y 90 monoclonal antibody, can find cancer cells and either kill them or carry cancer-killing substances to them without harming normal cells.

PURPOSE: This phase I trial is studying the side effects and best dose of a yttrium Y 90 monoclonal antibody and how much radiation is taken in by the organs in the body in treating patients with advanced leukemia or other hematologic disorder.

Read the detailed description

OBJECTIVES:

Primary

  • To establish that a dose of 150 mg/m² of nonradiolabeled anti-CD45 monoclonal antibody AHN-12 results in normal biodistribution, normal-organ estimated radiation-absorbed dose of less than 20 Gy, and estimated radiation-absorbed dose of no more than 13 Gy to the red marrow.

Secondary

  • To determine the maximum tolerated dose of yttrium Y 90 anti-CD45 monoclonal antibody AHN-12 (^90Y-AHN-12).
  • To determine the human anti-mouse antibody (HAMA) response.
  • To define, preliminarily, the antitumor activity of ^90Y-AHN-12.

OUTLINE: This is a dose-escalation study of yttrium Y 90 anti-CD45 monoclonal antibody AHN-12 (^90Y-AHN-12).

  • Biodistribution: Patients receive nonradiolabeled monoclonal antibody AHN-12 IV and an imaging dose of indium Y 111 monoclonal antibody AHN-12 (^111In-AHN-12) IV over 10 minutes on day 0. Patients undergo whole-body gamma-camera imaging immediately following infusion, at 4-6 hours, and on days 1, 3, 4, and 7. Blood samples are collected prior to each imaging for dosimetry calculations and pharmacokinetics.

Patients also undergo bone marrow biopsy 16-24 hours after infusion for dosimetry calculations. Patients with the expected biodistribution of ^111In-AHN-12, an estimated radiation-absorbed dose to the normal organ of < 20 Gy, an estimated radiation-absorbed dose to the red marrow of ≤ 13 Gy, and a negative human anti-mouse antibody at day 7 proceed to the therapy portion.

  • Treatment: Patients receive nonradiolabeled anti-CD45 monoclonal antibody AHN-12 IV over 60 minutes and escalating therapy doses of yttrium Y 90 anti-CD45 monoclonal antibody AHN-12 (^90Y-AHN-12) IV over 10 minutes on day 7 or 8.

After completion of study treatment, patients are followed periodically for 1 year.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing anti-CD45 monoclonal antibody AHN-12 and yttrium Y 90 anti-CD45 monoclonal antibody AHN-12 in people with Leukemia and Myelodysplastic Syndromes, run by Masonic Cancer Center, University of Minnesota 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 23 inclusion and 12 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 29 Nov 2017. 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: Replaced with another study). 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?

Biodistribution of nonradiolabeled anti-CD45 monoclonal antibody AHN-12 (time frame: Within 1 hour, 4-6 hours, Days 1, 3, 4 and 7 post infusion). 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 29 Nov 2017.
