Pharmacodynamics, Pharmacokinetics, Efficacy and Safety of Balugrastim in Pediatric Patients With Solid Tumors

January 13, 2015 updated by: Teva Branded Pharmaceutical Products R&D, Inc.

An Open Label, Randomized, Active Controlled, Dose Finding Study to Evaluate the Pharmacodynamics, Pharmacokinetics, Efficacy and Safety of Balugrastim at Doses of 300 µg/kg and 670 µg/kg in Pediatric Patients Diagnosed With Solid Tumors Receiving Chemotherapy

The primary objective of this study is to find the optimal dose of balugrastim by characterizing its pharmacokinetics (PK), and by comparing the pharmacodynamics (PD) of balugrastim to filgrastim in children receiving chemotherapy.

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.

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

  7. Female patients who have attained menarche must have a negative urine pregnancy test at the screening visit.
  8. White blood cell (WBC) count >2.5*10^9/L, ANC ≥1.5*10^9/L, and platelet count ≥100*10^9/L (at screening and prior to chemotherapy)

Exclusion Criteria:

  1. Primary myeloid disorders
  2. Prior radiation therapy within 4 weeks of randomization into this study.
  3. Previous exposure to filgrastim, pegfilgrastim, lenograstim or other G-CSF less than 6 months before randomization.
  4. Known hypersensitivity to filgrastim, pegfilgrastim, lenograstim or any balugrastim excipients
  5. Pregnancy or breastfeeding (if a patient becomes pregnant during the study she will be withdrawn from the study).
  6. Major surgery, serious infection, within 3 weeks before first administration of study drug, serious trauma or compound medical procedure within the 4 weeks prior to the first study drug dose.
  7. Subjects with a clinically significant or unstable medical or surgical condition that would preclude safe and complete study participation, as determined by medical history, physical exams, ECG, laboratory tests or imaging.

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
Area under the curve (AUC) of absolute neutrophil count (ANC)
Time Frame: Day 1 to 14

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.

Primary Completion (Anticipated)

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.
