Who can join

Age: 18 and older, up to 60. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• All Subjects:
• Male or female between 18 to 60 years of age (inclusive at the time of screening).
• Total body weight 50.0 to 100.0 kg, and body mass index (BMI) 19.0 to 35.0 kg/m2 (inclusive, at screening).
• Women can be of either childbearing or non-childbearing potential.
• Must be healthy with no clinically significant abnormality identified on medical or laboratory evaluation and no history of any clinically significant disorder, condition, or disease that would pose a risk to subject or interfere with the study evaluation, procedures, or completion as assessed by the Investigator.
• Subjects with Atopic Disease Only (Part B):
• Allergen skin test reactivity of ≥ 5 mm wheal greater than saline control to any 2 of the following 5 allergens: D. pteronyssinus, D. farina, ragweed, Virginia live oak, and mountain cedar within 21 days prior to dosing.
• Sufficient clinical control of subject's atopic disease such that, in the opinion of the Investigator, the subject is unlikely to require substantial changes in therapy medication for the duration of the trial and unlikely to require the addition of an exclusionary medication

You may not qualify if…

• Subjects who have a clinically relevant history or presence of respiratory, gastrointestinal, renal, hepatic, hematological, lymphatic, neurological, cardiovascular, psychiatric, musculoskeletal, genitourinary, immunological, dermatological, connective tissue diseases, or disorders that would pose a significant risk to subject's safety or significantly interfere with the study evaluation, procedures, or completion as assessed by the Investigator.
• Subjects with platelet count < 150 k/uL at screening or at the time of initial admission.
• Subjects with peak expiratory flow rate < 400 L/min for males and < 350 L/min for females.
• Subjects with conditions associated with high risk of bleeding such as: past history of intracranial or gastrointestinal bleeding, hemorrhagic condition including hereditary or acquired bleeding, or coagulation disorder.
• Subjects with history of any clinically significant cardiovascular event such as: myocardial infarction, acute coronary syndrome, stroke, pulmonary embolism, and/or deep venous thrombosis.
• Subjects who do not agree to use medically acceptable methods of contraception (as defined in the protocol).
• Subjects who are pregnant or breast feeding, or planning to become pregnant within 30 days of last dose of XmAb7195.
• Subjects who have used prescription drugs within 28 days prior to randomization with the following exceptions for Part B subjects with atopic disease:
• Intranasal corticosteroids for allergic symptoms if the dose has been stable for 14 days prior to randomization.
• Inhaled short acting beta agonist (SABA) therapy for bronchospasm if dosing has been stable for 14 days prior to randomization.
• No other prescription drugs are allowed unless agreed as not clinically relevant by the Investigator and Sponsor.
• Subjects who have had an asthma exacerbation requiring hospitalization within the 1 year prior to randomization or having required oral corticosteroids within the 6 months prior to randomization.
• Subjects with poorly controlled asthma defined as SABA > 6 times/day on any day within the 4 weeks prior to randomization.
• Subjects who have used any of the following medications within the 3 months prior to randomization: oral or inhaled corticosteroids, long acting beta agonists (LABAs), leukotriene receptor antagonists (LTRAs), or any other asthma controller medication (occasional SABA use is allowed).
