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 evaluated by the U.S. Federal Government. Read our disclaimer for details.

Brief Summary:
This is an exploratory, randomized, subject- and investigator-blinded, placebo-controlled mode-of-action study to demonstrate the anti-inflammatory effects of fevipiprant compared to placebo after 12 weeks of treatment in 48 moderate to severe asthma patients with sputum and blood eosinophilia.

Condition or disease Intervention/treatment Phase
Asthma Asthma, Bronchial Bronchial Asthma Eosinophilia Physiological Effects of Drugs Drug: QAW039 Phase 2

Detailed Description:
The main purpose of this study is to demonstrate the anti-inflammatory effects of fevipiprant (QAW039) compared to placebo after 12 weeks of treatment in moderate to severe asthma patients with an elevated sputum eosinophil count (≥ 2%) and high blood eosinophil count (≥ 250 cells/μL). This study is also designed to investigate the effects of fevipiprant on key inflammatory cells bearing the DP2 receptor (such as eosinophils, Th2/Tc2 cells, and ILC2 cells) in sputum and blood.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 0 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

This is a non-confirmatory, mode-of-action, placebo-controlled, parallel group, randomized, subject and investigator blinded study in 48 moderate to severe asthma patients, who are on at least medium dose ICS, with or without other asthma controller and with elevated sputum eosinophils count of ≥ 2% of the total cell count from an induced sputum specimen and a peripheral eosinophil count ≥ 250 cells/μL of blood. They should be on standard of care asthma medications for 4 weeks prior to screening with no past or current medical history of other chronic or severe pulmonary diseases. Randomized patients will be treated with fevipiprant or matching placebo for up to 98 days. A group of 10 healthy subjects will also be recruited to examine baseline levels of prostaglandins and DP2-related biomarkers and compare them to biomarker data from asthma patients at baseline and after therapy with fevipiprant.

Healthy volunteers will not receive study treatment.

.

Masking: Triple (Participant, Care Provider, Investigator)
Masking Description:

This is a subject and investigator-blinded study. Subjects, investigators and all site staff will remain blinded to study treatment throughout the study.

Unblinding a single subject at site for safety reasons (if necessary for subject management) will occur via an emergency system in place at the site.

The identity of the treatments will be concealed by the use of study drugs that are all identical in packaging, labeling, schedule of administration, appearance, and odor.

The sponsor may be unblinded to the study treatment at any time, especially in case of a safety concern.

Primary Purpose: Treatment

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

All Subjects (Asthma patients and healthy volunteers):

  • Written informed consent must be obtained before any assessment is performed.
  • Male and female subjects aged ≥ 18 years.
  • Able to communicate well with the investigator, to understand and comply with the requirements of the study.

Asthma patients:

  • Patients with a diagnosis of asthma currently prescribed at least medium dose of ICS, alone or with any other asthma controller therapy, except those listed as prohibited medications. Patients must be on stable doses of asthma medications for at least 4 weeks prior to screening.
  • A clinical diagnosis of asthma supported by at least one of the following within the last five years
  • Reversible airway obstruction defined as an increase of ≥ 12% and ≥ 200 ml in FEV1 or FVC over the patient's pre-bronchodilator value within 30 minutes after inhaling a total of 360 μg of albuterol or 400 μg salbutamol via metered dose inhaler (reversibility test)
  • A positive airway hyper-reactivity (AHR) test result defined as a provoked fall in FEV1 of 20% (PC20) by methacholine at ≤ 8 mg/ml when not on ICS or ≤ 16 mg/ml on ICS therapy
  • A change in FEV1 of ≥ 12% over two measurements within 12 months.
  • ACQ7 score ≥ 1.25 at screening and baseline visits and may be repeated once at each visit.
  • Demonstrate ability to produce a good quality induced-sputum sample at baseline visit.
  • Sputum eosinophil count ≥ 2% and blood eosinophil count ≥ 250cells/μL at applicable screening and baseline visits.

Healthy volunteers:

  • Subject must be in good health as determined by past medical history, current medications, physical examination, vital signs, electrocardiogram, and laboratory tests at screening.
  • Subjects with well-controlled, mild, non-respiratory diseases can participate as long as they are considered healthy and stable in the investigator's judgement.
