Alvelestat (MPH966), an Oral Neutrophil Elastase Inhibitor, in Bronchiolitis Obliterans Syndrome After Allogeneic Hematopoietic Stem Cell Transplantation
United States14 participantsStarted 2016-04-28
Plain-language summary
Background:
Bronchiolitis obliterans syndrome (BOS) is a complication people can experience after hematopoietic stem cell transplant. It usually affects people with chronic graft versus host disease (cGVHD). This occurs when donor stem cells attack the cells of the person who received them. BOS reduces airflow and oxygen levels in the body. It may be caused by neutrophil elastase in the body. Researchers believe the new drug alvelestat (MPH966) may help.
Objectives:
To test the safety of alvelestat (MPH966) and see what dose best inhibits neutrophil elastase in people with BOS after a stem cell transplant. To study how well the best dose improves lung function in those people.
Eligibility:
Adults 18 and older who have had a hematopoietic stem cell transplant and have cGVHD and BOS.
Design:
Participants will be screened with a medical history, physical exam, and blood and urine tests. They will have lung function and heart function tests. They will have computed tomography scans of the chest.
Study part 1: Participants will take the starting dose of the study drug by mouth twice a day for 14 days. This is 1 cycle. They will get different doses, for up to 4 cycles.
Study part 2: Participants will take the study drug twice a day by mouth at the dose set in part 1, for up to 12 months.
Participants will keep medicine diaries.
Participants will have several study visits. These may include:
Repeats of the screening tests.
Bronchoscopy with bronchoalveolar lavage.
Sputum samples taken.
6-minute walking test.
cGVHD assessment and answer questions.
Participants will be contacted after the study for up to 24 months.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Since this trial is in Phase 1/2 and is testing both the optimal dose and early safety of alvelestat at the same time, what does that mean for how much is already known about whether this drug is safe and effective for my specific situation?
2The trial is no longer enrolling new patients — does that mean there are any published or preliminary results from this study that you've seen, and could those results inform my treatment options even if I can't join?
3This trial targets neutrophil elastase inhibition in bronchiolitis obliterans syndrome after a stem cell transplant — given my current lung function and how my BOS is progressing, is this the kind of mechanism that might address what's driving my condition?
4Before considering a trial like this, should I first exhaust standard treatments for BOS and chronic graft-versus-host disease, or is there a reason to explore an experimental option like alvelestat sooner rather than later?
5Since the trial measures drug levels in sputum to find the right dose, can you help me understand what the monitoring and testing schedule would typically look like in a study like this, and whether that kind of commitment would be realistic for my day-to-day life?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Optimal biologic dose (OBD) based on maximal NE inhibition measured in sputum
Timeframe: 8 weeks after study drug initiation
2
To determine the clinical efficacy of MPH966 at the OBD in patients with BOS after SCT
