Sustained Asthma Remission and Reduced Relapse Using a Comprehensive Management Strategy (SARRE-COMS)

Prior treatment

• For the optional MRI procedure only: Patient has an implanted mechanically, electrically, or magnetically activated device or any metal in their body which cannot be removed, including but not limited to pacemakers, neurostimulators, biostimulators, implanted insulin pumps, aneurysm clips, bioprosthesis, artificial limb, metallic fragment or foreign body, shunt, surgical staples (including clips or metallic sutures and/or ear implants) (at the discretion of the MRI Technologist).

Other illness

• In the investigator's opinion, subject suffers from any physical, psychological or other condition(s) that might prevent performance of the optional MRI or CT, such as severe claustrophobia.

Other

• Primary respiratory diagnoses other than asthma (e.g., COPD, bronchiectasis) that would meaningfully affect study endpoints per discretion of clinical team.
• Patients with incomplete medical records.
• Patients who are already in a state of asthma remission.
• Patients with contraindications to PFT, sputum induction, CT imaging.
• Patients who are pregnant or breastfeeding.
• Patients who are unable or unwilling to comply with study procedures.
• Other contraindications to MRI.

• Patient understands study procedures and is will to participate in the study as indicated by the patient's signature.
• Provision of written, informed consent prior to any study specific procedures.
• Males and females ≥ 18 years of age.
• Diagnosis of severe asthma, as defined by ATS/ERS guidelines (requiring high-dose ICS plus second controller and/or OCS, or uncontrolled despite this therapy).
• Eligible for initiation of biologic therapy for treatment of asthma or already on active treatment but not yet in a state of four-domain asthma remission.
• Women of childbearing potential (after menarche) must ensure that they are using an effective form of birth control for at least 2 months prior to each imaging visit. Examples of effective birth control include:
• True sexual abstinence
• A vasectomized sexual partner
• Implanon®
• Female sterilization by tubal occlusion
• Effective intrauterine device (IUD)/levonogestrel intrauterine system (IUS)
• Depo-Provera™ injections
• Oral contraceptive
• Evra Patch™
• Nuvaring™
• Women of childbearing potential (after menarche) must agree to use a highly effective form of birth control, as defined above, from enrollment, throughout the study duration.
