Eligibility Criteria
You may qualify if:
- \. Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight \>50 kg (110 lbs).
You may not qualify if:
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, immunocompromised (or known disorder of the immune system), cardiovascular, hepatic, psychiatric, neurological, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).
- History of human immunodeficiency virus (HIV) infection, hepatitis B, or hepatitis C; positive testing for HIV, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), or hepatitis C antibody (HCVAb). Hepatitis B vaccination is allowed.
- History of active or latent tuberculosis (TB) regardless of treatment or positive QuantiFeron TB test.
- Participants with any of the following acute or chronic infections or infection history:
- Any infection requiring treatment within 2 weeks prior to the screening visit.
- Any infection requiring hospitalization, parenteral antimicrobial therapy within 30 days of the first dose of investigational product.
- Any infection judged to be an opportunistic infection, within the past 6 months of the first dose of the investigational product.
- Known active or history of frequent bacterial, viral, fungal, mycobacterial or other infections as determined by the PI.
- Participants with a fever within the last 7 days prior to dosing.
- Participants with a history of allergic or anaphylactic reaction to therapeutic or diagnostic protein.
- Other acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the participant inappropriate for entry into this study.
- Participants between the ages of 16 and 70 years old with a confirmed diagnosis of stable sickle cell disease (HbSS or HBS β0 thalassemia).
- Medical history of ≥2 and ≤ 10 medical utilization VOCs in 12 months prior to screening.
- ≥75% of daily ePRO diary completion, over a minimum of 14 days during the screening period.
- Fully vaccinated for COVID-19 in accordance with the Center for Disease Control guidance prior to Screening or must be negative for SARS-CoV-2 by polymerase chain reaction (PCR) within 72 hours of the Day 1 visit.
