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

This is a Phase 1, open-label, single-dose study in approximately 35 subjects with PKU who are 16 to 50 years old. Seven cohorts are planned, each consisting of 5 subjects; the cohorts as planned are 0.001, 0.003, 0.01, 0.03, 0.1, 0.3, and 1.0 mg/kg. Increasing doses of rAvPAL-PEG will be assessed sequentially until the final dose is evaluated or any of the stopping criteria are reached. Subjects will each receive a single dose and then will be followed for a total of 42 days (6 weeks) with visits to the clinical research unit (CRU) as specified in the Schedule of Events Toxicity will be measured according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE, v 3).

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

16 years to 50 years (ADULT, CHILD)

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
Measure Description
Time Frame
• To assess the incidence of treatment-emergent adverse events of a single, subcutaneous (SC) injections of rAvPAL-PEG in subjects with PKU.
Time Frame: 6 weeks
Specifically, safety was to be assessed by examining the incidence of all treatment-emergent adverse events reported during the study period and clinically significant changes in vital signs and clinical laboratory results, including development of rAvPAL-PEG antibodies.
6 weeks

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
Measure Description
Time Frame
• To evaluate the pharmacokinetics (PK) of single, SC injections of rAvPAL-PEG administered at escalating doses, in subjects with PKU.
Time Frame: 6 weeks
Specifically, exposure, AUC- and Cmax -dose proportionality, Tmax , λz and t1/2
6 weeks
• To evaluate the effect of different dose levels of rAvPAL-PEG on blood Phe concentrations in subjects with PKU.
Time Frame: 6 weeks
Specifically, exposure, AUC- and Cmax -dose proportionality, Tmax , λz and t1/2
6 weeks
