About this study
Official title: A Phase 2, Randomized, DB, Placebo-controlled Study to Determine the Efficacy, Safety and PK Profile of ARV-1801 in Combination With Optimized Background Therapy for the Treatment of Pulmonary Exacerbations in Patients With Cystic Fibrosis
This study will evaluate the efficacy and safety of an oral ARV-1801(ACG-701) plus optimized background therapy (OBT) compared to oral placebo plus OBT, each administered for 14 days, in the treatment of participants with Cystic Fibrosis-related pulmonary exacerbations (PEx).
Read the detailed description
This is a Phase 2, randomized, double-blind, multicenter study designed to evaluate the efficacy and safety of an oral ARV-1801/ACG-701 plus OBT compared to oral placebo plus OBT, each administered for 14 days, in the treatment of participants with CF-related PEx.
Participants who provide informed consent (plus informed assent, if applicable) and meet all study eligibility criteria will be enrolled in the study and randomized via an interactive response technology (IRT) in a 1:1 ratio to receive ARV-1801/ACG-701 or placebo in addition to OBT for 14 days. A participant may be hospitalized (inpatient) or treated as an outpatient. If admitted to the hospital for initial treatment, the participant may be discharged at the Investigator's discretion to complete study therapy as an outpatient. The target study population will comprise 80 participants.
The duration of participation in the study for an individual participant will be approximately 28 days and will involve up to 5 clinic visits as well as the requirement to complete an electronic symptom questionnaire every day for the duration of the study. Participation will include a Screening period of up to 24 hours prior to the first dose of study drug (Day 1), a 14 day treatment course of study drug, a Day 7 visit (±1 day), an end of treatment (EOT) visit (day of last dose of study drug +3 days), and end of study (EOS) visit on Day 28 (+3 days).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Sodium Fusidate in people with Cystic Fibrosis and Cystic Fibrosis Pulmonary Exacerbation, run by Aceragen at 25 sites in United States.
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 9 inclusion and 25 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: withdrawn, as of the sponsor's last update on 19 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 25 sites in United States. 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 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?
The study was withdrawn before enrolling participants, so there are no results.
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?
Desirability in outcome ranking (DOOR) (time frame: Day 7). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05641298, which also lists 1 linked publication.
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 19 Jul 2023.
