Plain English Summary

Background and study aims
The CHOICES study is conducted within the Human Individualised Therapy of CF (HIT-CF) project. The aim of this project is to provide drugs to people with cystic fibrosis (CF) who have (extremely) rare mutations and therefore do not have access to the currently available 'Cystic Fibrosis Transmembrane Conductance Regulator' (CFTR)-modulating drugs. CFTR modulators are a relatively new group of treatments that target the defect in CF. In the HIT-CF project, intestinal organoids ('mini-intestines') that have been cultured from the patient's own tissue (from rectal biopsies), are being tested in the laboratory to predict the predict clinical drug response to the CFTR modulators tested in this study: the three-part combination of dirocaftor (DIR)/posenacaftor (POS)/nesolicaftor (NES). Dirocaftor is a CFTR potentiator, posenacaftor is a CFTR corrector and nesolicaftor is a CFTR enhancer. Several proof-of-principle studies have shown that intestinal organoids can predict the clinical response to CFTR modulators in patients with rare mutations.

Who can participate?
The study population consists of subjects diagnosed with CF who are at least 18 years old (at the time of informed consent) and who have completed organoid screening (conducted by the HIT-CF consortium; HIT-CF organoid study [NTR7520]) prior to screening for this study.

What does the study involve?
Active and placebo study drugs are supplied as capsules for oral administration. The combination of dirocaftor, posenacaftor and nesolicaftor is given as a triple treatment in the following doses, respectively: 300 mg/day, 600 mg/day and 10 mg/day.
In both groups, suitable subjects will be randomised in a 1:1 ratio in one of 2 treatment series: either 8 weeks of DIR/POS/NES once a day followed by 8 weeks of placebo once a day.

Subjects come to the study site several times during each treatment period and a total of 10 times:
- Screening
- Treatment period 1 and 2: D1, D29, D43, D57
- Follow-up visit at D71
Blood, sweat and urine samples are collected at screening, in treatment periods 1, 2 and during the follow-up visit collected. One 12-lead electrocardiogram (heart monitor) and lung tests are done before the collection of blood samples. The CFQ-R is completed at each study visit, before procedures related to the study are done and before the study drug is administered on the day of the visit.

What are the possible benefits and risks of participating?
Possible benefits are that the study drugs may provide relief of, or lessening of, the signs and symptoms of CF; however, such a benefit cannot be guaranteed. The possible benefit to other people with this condition includes learning more information about treatment in patients who are diagnosed with CF.
Disadvantages of participation in the study may be:
-Possible side effects;
-Possible discomforts of the tests and measurements in the study. For example: taking a blood sample can be a little painful. Or you could get a bruise as a result

Scientific titleA phase IIb, multicentre, randomised, double-blind, placebo-controlled, crossover study to evaluate the efficacy and safety of dirocaftor/posenacaftor/nesolicaftor in subjects with cystic fibrosis aged 18 years or older
Study acronymCHOICES
Study hypothesis1. To evaluate the efficacy of DIR/POS/NES after 8 weeks compared to placebo in:
1.1. CF patients with rare CFTR mutations and a high organoid response to DIR/POS/NES
and
1.2. CF patients with rare CFTR mutations not pre-selected on organoid response.
2. To evaluate the safety and tolerability of efficacy of DIR/POS/NES in CF patients with rare CFTR mutations and to evaluate PK of DIR/POS/NES and their respective metabolites, when relevant.
Ethics approval(s)

ConditionTreatment of Cystic Fibrosis (CF) in patients with CFTR mutations who are responders in the organoid
assay
InterventionCHOICES is a randomized, double-blind, placebo-controlled, cross-over trial. The study population will comprise of subjects with a diagnosis of CF who are ≥18 years of age (at the time of informed consent) and have completed organoid screening (conducted by the HIT-CF consortium; HIT-CF Organoid Study [NTR7520]) prior to screening for this study. The study will consist of two groups. The first group will consist of 26 subjects of the HIT-CF Organoid Study with the highest organoid response to the combination of DIR/POS/NES. For the second group, 26 subjects, no such pre-selection criteria and no such screening will be performed (i.e. a simple random sample will be drawn instead). This approach will allow unbiased evaluation of the treatment effect in both populations, as well as for exploratory assessment of a possible difference in treatment effects. An unblinded coordinating team will be responsible for subject selection based on a subject’s organoid response and the detailed description will be captured in a separate sample and subject selection plan.
Subjects will participate in an 8-week, double blind, placebo controlled, cross-over study including an approximate 8 week washout period. In both groups, eligible subjects will be randomized at a 1:1 randomization ratio into one of 2 treatment sequences:
Either DIR/POS/NES once daily for 8 weeks followed by placebo once daily for 8 weeks, or placebo once daily for 8 weeks followed by DIR/POS/NES once daily for 8 weeks.
