Phase 1/2 Study of Intravenous or Intrapleural Administration of a Serotype rh.10 Replication Deficient Adeno-associated Virus Gene Transfer Vector Expressing the Human Alpha-1 Antitrypsin cDNA to Individuals With Alpha-1 Antitrypsin Deficiency

The ADVANCE study is being conducted by Adverum Biotechnologies, Inc. as an open-label, multicenter, dose-escalation study in order to assess the safety and protein expression of ADVM-043 following a single intravenous or intrapleural administration.

Detailed Description

Alpha-1 Antitrypsin (A1AT) is a major inhibitor of serine proteases and plays an important role in the lung as an inhibitor of neutrophil elastase. A1AT deficiency is associated with decreases in plasma A1AT levels and is associated with an increased risk for developing asthma, emphysema/COPD, and bronchiectasis. Much of the lung damage is thought to be caused by proteolytic damage from neutrophil elastase and other proteases.

ADVM-043 is an investigational gene therapy product (serotype AAVrh.10 vector) expressing human A1AT that is intended to deliver a functional gene to the liver of patients with A1AT deficiency. Study ADVM-043-01 will study up to 4 dose levels in up to 20 patients and assess the hypothesis that a single administration of an AAV vector expressing the human M-type A1AT (i.e., ADVM-043) to patients with A1AT deficiency is safe and results in persistent therapeutic levels of A1AT in blood and alveolar epithelial lining fluid (epithelial lining fluid is only to be collected in subjects who are dosed intrapleurally). The primary endpoint is safety, and changes in plasma A1AT levels at multiple time points up to 52 weeks after dosing. A prophylactic tapering corticosteroid regimen will be used to protect against potential vector induced transaminitis. Subjects will be followed for up to 52 weeks after dosing. Safety and efficacy data from the IV cohorts will be considered when determining whether to proceed to intrapleural administration. After completion of this study, subjects will be asked to enroll in a Long Term Follow Up study.

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
Treatment-emergent Adverse Events Related to ADVM-043
Time Frame: From ADVM-043 infusion through End-of-Study visit at 52 weeks
Number and proportion of subjects experiencing treatment-related adverse events related to ADVM-043
From ADVM-043 infusion through End-of-Study visit at 52 weeks
Abnormal Changes in Clinical Laboratory Parameters
Time Frame: From ADVM-043 infusion through End-of-Study visit at 52 weeks
Number of participants with ≥1 abnormal shift from Baseline in neutrophil count, hemoglobin, important serum chemistry parameters
From ADVM-043 infusion through End-of-Study visit at 52 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
Changes in Total Plasma Concentrations of A1AT up to 52 Weeks
Time Frame: At Week 52
Change from baseline at Week 24 and Week 52 of total A1At plasma concentration for subjects who did not receive PAT post -dose
At Week 52
Change in Plasma Concentrations of M-specific A1AT up to 52 Weeks
Time Frame: At Week 52

Change from baseline at Week 52 of plasma concentration of M-specific A1AT for subjects who did not receive PAT post-dose

Note:

  1. Two subjects in Dose 1 Arm/Group, had results available at Week 52; the remaining 4 subjects in Dose 2 Arm/Group and Dose 3 Arm/Group had resumed PAT therapy after Week 24, and their results were censored from the Week 52 timepoint.
  2. While data on the Total Plasma Concentrations of A1AT up to 52 Weeks were collected for 1 study participant in Part A: Dose 3, no data were collected on the Change in Plasma Concentrations of M-specific A1AT due to the initiation of PAT after 24 weeks in Part A: Dose 3 subjects.
At Week 52
