Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
* Genotypic confirmation of CFTR mutation or clinical diagnosis of Cystic Fibrosis (CF) confirmed by a sweat chloride value =60 mmol/L by quantitative pilocarpine iontophoresis.
* Age 18 years or older.
* Male or female patients with any ethnicity.
* FEV1 at screening in the range of =40% and 90% of the predicted normal for age, sex, and height, according to the GLI equation (Eur Respir J. Dec 2012; 40(6): 1324-1343).
* History of Pseudomonas aeruginosa (PA) infection with at least one positive microbiological PA testing during the last 12 months before the Screening Visit.
* History of antibiotic treatment due to PA infection (not for eradication therapy) during the last 12 months
* Concomitant treatment with inhaled tobramycin, colistin, or aztreonam (either cycled or continuous) for at least 3 months at screening to treat PA infection. In case of cycled antibiotic treatment, the treatment should start with an active cycle at the day of randomisation (+/- 2 day) (together with the IMP intake). If taking tobramycin cycled with another antibiotic, IMP should start on the active cycle of tobramycin.
* Stable CF disease as judged by the investigator.
* Willing to remain on a stable CF medication regimen (standard of care; SOC) during the study.
* Women of child-bearing potential must have a negative urine pregnancy test at the Screening and Randomisation Visit.
* Male and female patients must use acceptable contraceptive methods for the duration of the study. Male and female patients without child-bearing potential (i.e. who are infertile, surgically sterile or post-menopausal) are exempted from the contraceptive requirements. For the purpose of this study acceptable contraception is defined as one or a combination of the following:

* oral, injected, transdermal or implanted hormonal methods of contraception; placement of an intrauterine device (IUD) or intrauterine system (IUS); barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository.
* Capable of inhaling dry powder.
* Willing to sign informed consent
* Willing and able to follow the study procedures.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Use of hypertonic saline more than 2 times a day. If hypertonic saline is used, OligoG inhalation should be taken at least 15 minutes after completion of hypertonic saline therapy.
* Use of CFTR modulator therapies.
* Clinically significant abnormal findings of haematology or clinical chemistry;

* Elevated gamma GT (GGT), ALT, or AST > 3x the upper normal limit of normal (ULN)
* Bilirubin >2x ULN
* Abnormal renal function, with a creatinine clearance calculated <50ml/min
* Haemoglobin <10g/dL
* History of any comorbidity that, in the opinion of the investigator, might distort the results of the study or cause an additional risk in administering study drug to the patient.
* Pulmonary exacerbation within 28 days prior to randomisation.
* Change in CF therapy within 28 days before randomisation (first dose of IMP).
* Pregnant or breastfeeding females.
* History of allergic reactions to the ingredients of the IMP according to Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or 4, including lactose and milk protein.
* Patients unable to perform pulmonary function tests according to the ATS/ERS criteria.
* Uncontrolled or unstable chronic diseases (e.g. congestive heart failure, cardiac arrhythmia, or psychiatric illness/social situations) that would limit the compliance with study requirements in the opinion of the investigator.
* Any acute illness in the last 14 days
* History of, or planned organ transplantation.
* Lung infection with organisms associated with a more rapid decline in pulmonary status (including, but not limited to Burkholderia cenocepacia, Burkholderia dolosa, and Mycobacterium abscessus). For subjects who have had a history of a positive culture, the following criteria will be used to determine whether the subject is free of infection with such organisms:-

* The subject has not had a respiratory tract culture positive for these organisms within the 12 months before the date of informed consent, and
* The subject has had at least 2 respiratory tract cultures negative for such organisms within the 12 months before the date of informed consent, with the first and last of these separated by at least 3 months, and the most recent one within the 6 months before the date of informed consent.
* Active allergic bronchopulmonary aspergillosis (ABPA) in the last 12 months prior to the Screening Visit, that has received pharmacological treatment for ABPA.
* Requirement for continuous (24 hour/day) oxygen supplementation.
* Patients currently receiving any other investigational treatment, or who have participated in a clinical study within 4 weeks (28 days) prior to the screening visit.
* Current malignant disease (with the exception of basal cell carcinoma and cervical neoplasia).
* Any medical or psychological condition, other than CF, which in the opinion of the investigator exposes the patient to an unacceptably high risk.
* Patients with documented or suspected, clinically significant, alcohol or drug abuse as per Investigator's discretion.
