What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The safety of ALN-AAT evaluated by the proportion of subjects experiencing adverse events (AEs), serious adverse events (SAEs), and AEs leading to study drug discontinuation

    Measured: Part A (SAD phase): through day 70; Part B (MAD) phase: through Day 154; Part C: through Day 224

Secondary outcomes (2)
  1. Profile of Pharmacokinetics (PK) of ALN-AAT

    Cmax, tmax, AUC, t1/2

    Measured: Part A (SAD) phase: up to 21 days; Part B (MAD) phase: up to 105 days; Part C: up to 161 days

  2. The effect of ALN-AAT on serum levels of AAT protein

    Measured: Part A (SAD) phase: through day 70; Part B (MAD) phase: through Day 154; Part C: through Day 224

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ALN-AAT and Sterile Normal Saline (0.9% NaCl) in people with Antitrypsin Deficiency Liver Disease, run by Alnylam Pharmaceuticals at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 7 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Observation of low incidence of asymptomatic, transiently elevated liver enzymes in a subset of study subjects). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The safety of ALN-AAT evaluated by the proportion of subjects experiencing adverse events (AEs), serious adverse events (SAEs), and AEs leading to study drug discontinuation (time frame: Part A (SAD phase): through day 70; Part B (MAD) phase: through Day 154; Part C: through Day 224). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jan 2019.
