About this study

Official title: A Phase 1/2 Dose-exploration and Dose-expansion Study to Evaluate the Safety and Efficacy of BEAM-302 in Adult Patients With Alpha-1 Antitrypsin Deficiency (AATD)-Associated Lung Disease and/or Liver Disease

This is a Phase 1/2, multicenter, open-label study conducted in 3 parts (Part A, Part B, and Part C) to evaluate the safety, tolerability, PK/PD, and efficacy of BEAM-302 in adult patients with AATD-associated lung disease and/or liver disease. Parts A and B are designed to evaluate safety and tolerability and identify the optimal biological dose (OBD) in patients with AATD-associated lung disease (Part A) and/or liver disease (Part B), with optional expansion cohorts to further evaluate a potential OBD. Part C is designed to demonstrate the efficacy and safety of BEAM-302 at the OBD in patients with AATD-associated lung disease with or without liver disease in the pivotal cohort.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing BEAM-302 in people with Alpha 1-Antitrypsin Deficiency, run by Beam Therapeutics Inc. at 12 sites in 6 countries.

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 17 inclusion and 14 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: looking for participants now, as of the sponsor's last update on 5 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States, United Kingdom, Australia, New Zealand, Ireland and 1 more country. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Medical Information (857-327-8641, clinicalinfo@beamtx.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rates of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs) (time frame: 3 years). The study lists 3 primary outcomes in all. 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 5 Oct 2026.
