Overview
The study is being conducted to evaluate the effect of 3 dosing regimens of povorcitinib on pulmonary function
Eligibility
Inclusion Criteria:
- Physician-diagnosed asthma requiring treatment with medium- to high-dose ICS-LABA for at least 12 months prior to screening.
- Pre-BD FEV1 < 80% predicted according to central over read value at Visit 2.
- Documented historical post-BD reversibility of FEV1 ≥ 12% and ≥ 200 mL in FEV1 within 12 months prior to screening OR Post-BD reversibility of FEV1 ≥ 12% and ≥ 200 mL in FEV1 according to central over read value at Visit 2.
- At least 2 documented asthma exacerbations (requiring treatment with systemic CS, hospitalization, or emergency department visit) within 12 months prior to screening but not within the past 4 weeks prior to screening
- ACQ-6 ≥ 1.5 at screening.
Exclusion Criteria:

- Any malignancies or history of malignancies. Note: Participants with cured nonmetastatic basal cell or squamous cell carcinoma of the skin, superficial bladder cancer, prostate intraepithelial neoplasm, carcinoma in situ of the cervix, or other noninvasive malignancy or cancers from which the participant has been disease-free for > 1 year after treatment with curative intent are eligible.
