You may qualify if…

Ability to comprehend and willingness to sign a written ICF for the study.
Aged 18 to 55 years, inclusive, at the time of signing the ICF.
Body mass index within the range of 18.0 to 30.0 kg/m2 (inclusive) at screening.
Note: Participants with a BMI up to 32.0 kg/m2 may be enrolled with the sponsor's approval.
Body weight of ≥ 40 kg (inclusive). Note: For each cohort, approximately 6 participants from 1 of each weight band (40-65 kg, > 65-90 kg, > 90 kg) will be enrolled, to total approximately 24 participants in each weight band.
No clinically significant findings on screening evaluations (clinical, ECG, and comprehensive physical examination, including the eyes). No laboratory values out of normal reference ranges.
Ability to be administered IV or SC study drug.
Willingness to avoid pregnancy or fathering children based on the protocol defined criteria below.
Male participants with reproductive potential must agree to take appropriate precautions to avoid fathering children, including refraining from donating sperm, from screening through 90 days (a spermatogenesis cycle) after the dose of study drug on Day 1 and must refrain from donating sperm during this period. Permitted methods in preventing pregnancy should be communicated to the participants and their understanding confirmed.
Female participants who are WOCBP must have a negative pregnancy test at screening and a negative pregnancy test at check-in (Day -1) and must agree to take appropriate precautions to avoid pregnancy from screening through 60 days (2 menstrual cycles) after the dose of study drug on Day 1 and must refrain from donating oocytes during this period. Permitted methods in preventing pregnancy should be communicated to the participants and their understanding confirmed.
Female participants not considered to be of childbearing potential as defined in the protocol are eligible and must have a negative pregnancy test at screening and check-in.

You may not qualify if…

History of uncontrolled or unstable respiratory, renal, gastrointestinal, endocrine, hematopoietic, psychiatric, and/or neurological disease within 6 months of screening.
History of cardiovascular, cerebrovascular, peripheral vascular, or thrombotic disease or uncontrolled hypertension.
High blood pressure (systolic blood pressure > 140 mmHg or diastolic blood pressure > 90 mmHg at screening, confirmed by repeat testing).
Resting pulse rate < 40 bpm or > 100 bpm at screening. May repeat up to 3 total measurements, separated by 5 minutes, to confirm.
History of rheumatologic/autoimmune disorders, except for minor eczema and rosacea.
History or presence of an abnormal ECG before initial dose administration that, in the investigator's opinion, is clinically significant. Participants with a QTcF interval > 470 milliseconds, regardless of sex. QRS interval > 120 milliseconds, or PR interval > 220 milliseconds will be excluded. In the event a value is exclusionary, a single ECG will be repeated twice, and an average taken of the 3 readings will be used to determine if a participant should be excluded.
History of malignancy within 5 years of screening, with the exception of cured basal cell or squamous cell carcinoma of the skin, ductal carcinoma in situ, or Gleason 6 prostate cancer.
Any major surgery within 4 weeks of screening.
Donation of blood to a blood bank or participation in a clinical study (except a screening visit) within 4 weeks of screening (within 2 weeks for donation of plasma only).
Blood transfusion within 4 months of check-in (Day -1).
Chronic or current active infectious disease requiring systemic antibiotics, antifungal, or antiviral treatment (includes latent treated tuberculosis).
Positive test for HBV, HCV, or HIV. Participants whose results are compatible with prior immunization for or immunity due to infection with HBV may be included at the discretion of the investigator.
Any chronic or recurrent edema. History of urticaria, allergic rhinoconjunctivitis, seasonal atopic, food, and/or latex allergy.
Medical or self-reported history of alcoholism within 3 months of screening.
History of significant alcohol use within 3 months of screening, defined as regular alcohol consumption > 21 units per week for males and > 14 units for females (1 unit = one-half pint of beer or a 25 mL shot of 40% spirit, 1.5 to 2 units = 125 mL glass of wine).
Has received a live vaccine (including attenuated) or anticipation of need for such a vaccine during the study.
Note: No vaccines may be administered within 3 months prior to the first dose of study drug.
Positive urine or breath test for ethanol or positive urine or serum screen for drugs of abuse that are not otherwise explained by permitted concomitant medications or diet.
Current treatment or treatment within 30 days or 5 half-lives (whichever is longer) before the first dose of study drug with another investigational medication or current enrollment in another investigational drug or investigational product study.
History of any significant drug allergy (such as anaphylaxis or hepatotoxicity) deemed clinically relevant by the investigator.
Previous receipt of axatilimab.
Known hypersensitivity or severe reaction to axatilimab or excipients of axatilimab.
Inadequate veins for multiple venous puncture or IV catheter insertion as determined by the investigator or designee.
Inability or unlikeliness of the participant to comply with the dose schedule and study evaluations, in the opinion of the investigator.
History of tobacco or nicotine-containing product use within 1 month of screening.
