About this study

Official title: A Phase I Study of CYT107 (Recombinant Glycosylated Human IL-7) in Recipients of HLA Matched Ex Vivo T Cell Depleted Bone Marrow or Peripheral Blood Stem Cell Transplant

This is a phase I inter-patient dose escalation open labeled study assessing multiple doses of CYT107 in patients of at least 15 years of age, who are recipients of HLA matched ex vivo T cell depleted bone marrow or peripheral blood stem transplants.

The dose escalation design is aimed at establishing the absence of significant toxicity and to define a biologically active dose in this patient population.

Read more

At each dose level, eligible patients will receive 3 doses of CYT107 injected subcutaneously (under the skin of the arm, legs, or stomach) once a week for 3 weeks.

Groups of three patients will be entered at each dose level of CYT107. Three dose levels are planned: 10 mcg/kg/week, 20 mcg/kg/week and 30 mcg/kg/week. Three patients must complete day 42 of the study at a dose level without a dose limiting toxicity (DLT) before there is escalation to the next dose level.

Read the detailed description

Rationale: Delayed and deficient reconstitution of T cells and their functions are a major obstacle to the success of a hematopoietic stem cell transplant (HSCT). CYT-107 may have potential clinical use after allogeneic HSCT to enhance lymphoid reconstitution which could have a number of beneficial effects including decreased morbidity and mortality from post-transplant infections. Our preliminary data with a previous generation IL-7, CYT 99 007, raise the possibility that IL-7 could have, in some cases, an anti-GVHD effect while keeping the anti-tumor effect of the allograft intact.

Primary Objective:

  • To determine the safety and a recommended dose of CYT107 (r-hIL-7) in recipients of an HLA-matched related or unrelated ex vivo T-cell-depleted bone marrow (BM) or peripheral blood stem cell (PBSC) transplant after initial engraftment and hematopoietic reconstitution.
  • If toxicities are encountered, to establish the maximum tolerated dose (MTD) and dose limiting toxicities (DLT).

Secondary Objectives:

  • To define the pharmacokinetics of escalating doses of CYT107 in recipients of allogeneic transplants.

To achieve preliminary characterization:

  • Of the effects of CYT107 treatment on engraftment and GVHD.
  • Of the effects of CYT107 on the recovery of T, NK and B cell populations and their functions in vitro.
  • Of a tolerable biologically active range of doses for CYT107 in recipients of allogeneic transplants.
  • Whether and to what degree administration of CYT107 might influence the risk of developing an EBV-lymphoproliferative disorder.
  • Of the effects of CYT107 treatment on leukemia relapse.

    Patients will be treated with CYT107 60 to 210 days post transplantation, in 3 successive cohorts of 3 patients. Escalating doses of CYT107 will be given to successive cohorts. Patients will receive 1 dose of CYT107 by the subcutaneous route, once a week for 3 weeks. Dose level 1: 10 mcg/kg/dose for 3 doses; Dose level II: 20 mcg/kg/dose for 3 doses; Dose level III: 30 mcg/kg/dose for 3 doses. Only 1 treatment course for this initial study.

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 19 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 26 Jul 2012. 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 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?

Toxicity of CYT107 in post-transplant patients with AML, CML and MDS using the NCI Common Toxicity Criteria version 3.0 with the BMT specific adverse event grading system. (time frame: Visits: 2 week screening period; treatment visits on days 0, 7, and 14; non-treatment visits on Days 1, 21, 28, 42, 56, and 77.). 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 NCT00684008, which also lists 3 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 26 Jul 2012.
