NCT ID NCT03587961

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

Summary

This early-phase trial is testing whether certain cystic fibrosis drugs, called CFTR modulators, can help people with rare gene mutations that are not currently approved for these medications. The study will enroll 20 participants aged 6 and older and measure changes in lung function. The goal is to see if personalized treatment can improve breathing in patients who have few other options.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Symdeko (also known as Orkambi, Ivacaftor)
What this could lead to
If it works, this could expand treatment options for people with cystic fibrosis who have rare mutations not currently covered by approved drugs.
What could go wrong
This is a very early, small trial with only 20 participants, so results may not apply widely. The drugs are used off-label and may not work for all mutations, and there are risks like side effects or no improvement in lung function.

Inclusion Criteria: * Diagnosis of CF * Age ≥6 y.o. * CFTR mutation that may respond to approved correctors/potentiators in the opinion of the study investigators * Informed Consent/Assent * Stable CF pulmonary regimen Exclusion Criteria: * Exacerbation requiring antibiotic or steroids for \>28 days before trial entry * Ongoing participation in a CFTR modulator study * Active smoking in the past 6 months * History of solid organ transplant * Any condition which precludes the use of CFTR modulators: e.g. advanced cirrhosis, End-stage Renal Disease (ESRD) * Any condition that precludes the patient from participation in the opinion of the investigator * Any meds that have significant drug-drug interactions or any other off label use of CFTR modulators
