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

Experimental: 4D-310 Dose Level 1 - AAV Neutralizing Antibody (NAb) Group A
Single IV administration of 4D-310 Dose Level 1 - AAV NAb Titer Group A patients
Biological: 4D-310
4D-310 is a novel adeno-associated virus (AAV) gene therapy comprised of two active components: the capsid (4D-C102) and the transgene cassette, which encodes a codon-optimized full length human GLA transgene driven by the CAG promoter. 4D-310 has been engineered so that it cannot replicate (replication incompetent).

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
Incidence and severity of adverse events
Time Frame: 1 year
Safety and tolerability of 4D-310 following a single IV dose, as assessed by incidence and severity of adverse events, serious adverse events and dose limiting toxicities, including clinically significant changes from baseline to scheduled time points in safety parameters
1 year

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
