History of or a current immunosuppressive condition Symptoms of clinically significant illness in the 3 months before the initial study drug administration. Any concurrent illness, condition, disability, or clinically significant abnormality Treatment with any drug known to have a well-defined potential for toxicity to a major organ in the last 3 months preceding the initial study drug administration. A history of significant psychological, neurologic, hepatic, renal, endocrine, cardiovascular, gastrointestinal (GI), pulmonary, or metabolic disease. MAD only Active (skin) infection requiring systemic antibiotics immunosuppressive/immunomodulating drugs or phototherapy 4 weeks prior to baseline Treatment with topical corticosteroids (TCS) or topical calcineurin inhibitors (TCI) within 2 weeks before the baseline Treatment with biologics within 5 half-lives (if known) or 12 weeks prior to baseline visit history of immunosuppression Regular use (more than 2 visits per week) of a tanning booth/ parlor within 4 weeks of the screening visit Regular daily use of oral nonsteroidal anti-inflammatory drugs (NSAIDs), except low-dose aspirin (≤200 mg/day) for cardioprotection, within 7 days prior to screening

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Difference as compared to placebo in the number of subjects with treatment-emergent adverse events | To evaluate the safety and tolerability of single ascending doses of MOR106 intravenously given to healthy male subjects and of multiple ascending doses of MOR106 given intravenously to subjects with atopic dermatitis, compared to placebo | Up to 99 days after dosing | 
| Difference as compared to placebo in the number of subjects with deviating physical examination results | To evaluate the safety and tolerability of single ascending doses of MOR106 intravenously given to healthy male subjects and of multiple ascending doses of MOR106 given intravenously to subjects with atopic dermatitis, compared to placebo | Up to 99 days after dosing | 
| Difference as compared to placebo in the number of subjects with abnormal vital signs | To evaluate the safety and tolerability of single ascending doses of MOR106 intravenously given to healthy male subjects and of multiple ascending doses of MOR106 given intravenously to subjects with atopic dermatitis, compared to placebo | Up to 99 days after dosing | 
| Difference as compared to placebo in the number of subjects with abnormal 12-lead ECG results | To evaluate the safety and tolerability of single ascending doses of MOR106 intravenously given to healthy male subjects and of multiple ascending doses of MOR106 given intravenously to subjects with atopic dermatitis, compared to placebo | Up to 99 days after dosing | 
| Difference as compared to placebo in the number of subjects with abnormal laboratory findings | To evaluate the safety and tolerability of single ascending doses of MOR106 intravenously given to healthy male subjects and of multiple ascending doses of MOR106 given intravenously to subjects with atopic dermatitis, compared to placebo | Up to 99 days after dosing |
