A Study of Safety, Tolerability, and Pk of rhMBL in Pediatric Hematology/Oncology Pts With Fever and Neutropenia

September 4, 2012 updated by: Enzon Pharmaceuticals, Inc.

A Multi-Center Study of the Safety, Tolerability, Pharmacokinetics, and Dose Escalation of Intravenous Recombinant Human Mannose-Binding-Lectin (rhMBL) in MBL Deficient Pediatric Hematology/Oncology Patients With Fever and Neutropenia

The goal of this clinical research study is to find the dose of EZN-2232 that can be given to MBL deficient pediatric cancer patients undergoing chemotherapy. The pharmacokinetics, pharmacodynamics, and safety of the study drug will also be studied.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

MBL deficient patients will be randomized in a ratio of 1:1 to receive a single dose of either 0.5 mg/kg or 1.0 mg/kg of intravenous rhMBL. A total of 24 patients will be treated in each of the rhMBL arms, (12 in the 0.5 mg/kg and 12 in the 1.0 mg/kg. All patients are to receive anti-infectious prophylactic supportive therapy as per institutional standards

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

2 years to 17 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria: Patients must meet all of the following criteria to be eligible for enrollment into the study:

  • Children ages 2 to 17 receiving chemotherapy for hematological/oncological diseases.
  • Patients must have documented MBL levels <300 ng/mL in serum as evaluated in the screening protocol.
  • Fever defined as an oral temperature equivalent of >100.4°F (38°C).
  • Neutropenia defined as an absolute neutrophil count ≤1,000/mm3 with the anticipation that the counts will fall below 500/mm3.
  • Receiving broad spectrum antibiotics for fever and neutropenia.
  • Patients with age-adjusted normal serum creatinine OR a creatinine clearance >60 mL/min/1.73m2.
  • Informed consent of the patient, parent or legally authorized representative obtained prior to entry.
  • Reliable and willing to make themselves available for the duration of the study and to abide by the study restrictions.

Exclusion Criteria: Patients meeting any of the following exclusion criteria will not be eligible for enrollment.

  • Patients receiving the preparative regimen for a bone marrow or hematopoietic stem cell transplantation.
  • Concurrent serious illness in the opinion of the principal investigator that could potentially interfere with protocol compliance.
  • Patient is pregnant, breast feeding or planning a pregnancy during the course of the study.
  • Sexually active male and female patients not using an acceptable barrier method of contraception or practicing abstinence throughout the study and for at least 30 days after receiving their last treatment unless the patient is surgically or medically sterile.
  • Patients with moderate or severe liver disease, as defined by:

AST or ALT >5 times upper limit of normal (ULN) OR Total bilirubin >2.5 times ULN.

  • Patients with poor venous access that would preclude intravenous drug delivery or multiple blood draws.
  • Current participation in another clinical study with an investigational agent and/or use of an investigational drug (not including investigational use of an FDA approved drug) in the 30 days before scheduled administration of rhMBL.
  • Known allergic reactions to MBL or other human plasma products.
  • Patients on hemodialysis unable to tolerate the volume of IV fluid on non-dialysis days.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Determine the safety and tolerability of intravenous rhMBL administered at dosages of 0.5 and 1.0 mg/kg to MBL deficient pediatric hematology/oncology patients during episodes of fever and neutropenia.
Time Frame: 1 month
1 month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Determine the PK profile of intravenous rhMBL as a single dose escalation cohort design in MBL deficient pediatric oncology patients during episodes of fever and neutropenia.
Time Frame: 1 month
1 month

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
