About
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).
Full 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).

Participants must have a negative pregnancy test and agree to use a highly effective method of contraception during the study and 30 days after last dose
Participants must agree not to smoke during any part of the clinical trial
Participants must voluntarily sign the informed consent for the study
Exclusion criteria
Participants cannot have any changes in any antimicrobial, bronchodilator, anti-inflammatory, CFTR modulator or corticosteroid medications from 28 - 3 days prior to the Screening visit.
Participants cannot be receiving treatment for non-tuberculosis mycobacteria and/or Aspergillus infection.
History of hypersensitivity or allergic reaction to sodium fusidate, fusidic acid (Fucidin®) or its excipients.
Abnormal laboratory findings or other findings or medical history at Screening that, in the Investigator's opinion, would compromise the safety of the participant or the quality of the study data.
The use of an investigational drug or device (ie, a drug or device without the FDA approved indication) within 30 days prior to the Screening visit
Known severe renal impairment, as indicated by estimated creatinine clearance (CrCl) <30 mL/min (by Cockcroft-Gault calculation).

Malignancy requiring ongoing cytotoxic chemotherapy or radiation therapy.
Requires concomitant treatment with (washout period prior to randomization allowed):
Prior treatment with a CYP3A4 inducer (such as lumacaftor, dexamethasone, phenytoin, carbamazepine, rifampin, phenobarbital and nafcillin) within 7 days prior to enrollment.
Dietary use of large amounts of grapefruit juice and/or Seville oranges or other products containing these fruits (eg, grapefruit juice or marmalade) during the study.
Participant requiring warfarin therapy.
