Inclusion criteria

To be eligible to participate in this study, all of the following criteria must be met:

• An Independent Ethics Committee (IEC)-approved written Informed Consent Form is signed and dated by the subject

• Subject is considered reliable and capable of adhering to the protocol (eg, able to understand and complete diaries), visit schedule, or medication intake according to the judgment of the Investigator

• Subject is male or female, 18 to 55 years of age (inclusive)

• Female subjects must have a negative pregnancy test in urine at the Screening Visit and a negative serum pregnancy test on Day -1, and be of nonchildbearing potential, defined as being:

  1. Postmenopausal (for at least 2 years before the Screening Visit), verified by serum follicle-stimulating hormone (FSH) level >40 mIU/mL at the Screening Visit, or
  2. Permanently sterilized (eg, tubal occlusion, hysterectomy, bilateral salpingectomy), or
  3. Congenitally sterile

• Contraception methods for male subjects and their female partners:

  1. Male subject with a partner of childbearing potential must be willing to use a condom when sexually active
  2. The female partner of childbearing potential of a male subject must be willing to use at least 2 effective methods of contraception, including a barrier method (eg, male condom, female condom, or diaphragm with spermicide) during the study period.

Both sexes must use the above mentioned contraception methods (condoms for males) during the study and for 20 weeks after the last administration of the Investigational Medicinal Product (IMP) (anticipated 5 half-lives).

• Subject is of normal weight as determined by a body mass index (BMI) of 18.0 to 30.0 kg/m^2 (inclusive), with a body weight of at least 50 kg
• Subject has clinical laboratory test results within the reference ranges of the testing laboratory
• Subject has Blood Pressure (BP) and pulse within normal range in a supine position after 5 minutes rest (systolic BP: 90 to 140 mmHg, diastolic BP: 50 to 90 mmHg, pulse: 40 to 90 beats per minute - all inclusive)
• Subject's ECG is considered "normal" or "abnormal but clinically nonsignificant" (as interpreted by the Investigator)

Exclusion criteria

Subjects are not permitted to enroll in the study if any of the following criteria is met:

• Subject has a known hypersensitivity to any components of the Investigational Medicinal Product (IMP)

• Subject is considered anti-high-affinity immunoglobulin E (IgE) receptor nonresponsive if CD63 induction on basophils is <10 %

• Subject has cardiovascular or cerebrovascular disease, including hypertension, angina, ischemic heart disease, transient ischemic attacks, stroke, and peripheral arterial disease sufficient to cause symptoms and/or require therapy to maintain stable status

• Subject has diabetes mellitus of any type requiring insulin

• Subject has

  1. an active infection (eg, sepsis, pneumonia, abscess)
  2. history of latent, chronic, or recurrent infections (eg, tuberculosis [TB], recurrent sinusitis, genital herpes, urinary tract infections) or at risk of infection (surgery, trauma, infection requiring antibiotics, history of skin abscesses) within 3 months before IMP administration
  3. experienced a significant episode of gastroenteritis (defined as loose stools associated with abdominal pain and/or fever) during the 7 days before IMP administration

When in doubt, the Investigator should confer with the Sponsor's Study Physician.

• Subject has a history of positive TB test or evidence of possible TB or latent TB infection at the Screening Visit (QuantiFERON® Gold Test)
• Subject has received live attenuated vaccination within 3 months or any other type of vaccine within 4 weeks before the Screening Visit or intends to have such a vaccination during the course of the study
• Subject who has any of the following hematology values at the Screening Visit: Hemoglobin; for women <11 g/dL; for men <13 g/dL Absolute Neutrophil Count (ANC) <1.5 x 109/L (<1000/mm^3)
