How long will the WILLOW Study take?

The WILLOW Study will last for up to 34 weeks (just over 8 months) for each participant. This includes:

  • A 6-week Screening period
  • A 24-week Treatment period
  • A 4-week Follow-up period.

How many visits will I need to attend?

You will be required to attend approximately 10 visits to the Study Centre:

  • Screening Period - You may be asked to attend the site for several visits to complete screening assessments
  • 8 visits during the Treatment period
  • One for the End of Study visit.

What treatment will I be given?

If you are eligible and you choose to take part in this study, you will be allocated to one of three treatment groups:

  • Investigational Medication 10-mg dose
  • Investigational Medication 25-mg dose
  • Dummy (placebo) treatment
You have an equal chance of being in any of these three treatment groups. The treatment allocation is “blinded”. This means that your doctor and other Study Centre staff will not know which treatment you are on and neither will you.

What procedures and assessments are involved?

At each visit, you will need to have different assessments and procedures performed, ranging from filling out forms and answering questionnaires, to having blood and urine samples taken. These will change at the different visits. You will also have various physical measurements taken, such as your height, weight and blood pressure, as well as an electrocardiogram (ECG), which measures the electrical activity of your heart. You may have to undergo a Computed Tomography (CT) scan if you have not previously had confirmation of a Non-Cystic Fibrosis Bronchiectasis (NCFBE) diagnosis

What safety measures are in place?

Your health will be monitored throughout the WILLOW Study and at each study visit you will be asked to report any side effects you have experienced.

In the case of an emergency, there is a procedure in place to find out what treatment you are on so that you can receive the correct care.

What if I am unable to attend a visit?

You will need to contact the Study Centre staff as soon as possible to try and rearrange your visit. It is important to attend all visits within the time range permitted (within 3 days either side of the date), so we ask that you are committed to attending the agreed visit times as much as possible.

Will it cost me anything to participate in the WILLOW Study?

You do not have to pay for the study medication, study visits or any tests that are part of the study. You may be reimbursed for necessary expenses (e.g the cost of your transport to and from visits).
