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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Study procedures:

A. Study period: 36 months; treatment period: 12 months.

B. Patients will receive Carglumic Acid (Carbaglu®) 50 mg/kg/day in addition to standard therapy (protein restricted diet, L-carnitine, metronidazole and vitamin B12).

C. Patients need to regularly come back for follow up examination on Day 0, month 3, month 6, and month 12.

D. Patients should report any adverse event that occur during treatment period.

E. Patients' number of emergency visits due to hyperammonemia, ammonia level, acylcarnitine, urinary organic acid analysis, plasma amino acid analysis and methylmalonic acid will be recorded during treatment period.

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

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

18 years and older (Child, Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  1. PA or MMA confirmed using the following criteria:

    • PA confirmed by the measurement of acylcarnitine profile, urine organic acid, measurement of propionyl Co-A carboxylase in leukocytes or cultured fibroblasts or by DNA molecular testing of PCCA (Propionyl CoA Carboxylase, Alpha Polypeptide) or PCCB (propionyl CoA carboxylase, beta polypeptide) gene
    • MMA confirmed by the measurement of acylcarnitine profile, urine organic acid, measurement of methymalonyl Co-A mutase in culture fibroblasts or DNA molecular testing of mutgene.
  2. Male or female Children of 18 years old or less.
  3. Had experienced Hyperammonemia(NH3 ≧100 uM) before.
  4. Not participating in any other clinical trial in the previous 30 days

Exclusion Criteria:

  1. Patients with other organic acidemia or any other cause of hyperammonemia

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: 12 months
Adverse Events

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.
