Primary Outcome Measures:
  • Proportion of subjects with and the amplitude and timing of adverse events, proportion of subjects with and the grade and timing of abnormal lab values, and proportion of subjects with and timing of changes in physical exam findings and vital signs [ Time Frame: Up to 7 days after dosing ] [ Designated as safety issue: Yes ]

Single subcutaneous escalating dose
Placebo Comparator: Placebo Drug: placebo
placebo

Detailed Description:

This is a Phase 1, randomized, single-blind, placebo-controlled study of five escalating dose levels of SD-101 in healthy male volunteers. The objectives of the study are to assess the safety, tolerability, pharmacokinetic profile, and pharmacodynamics of SD-101. Approximately 40 subjects will participate.

Once subjects have been consented, screened, and assigned to one of the dose levels of SD-101, subjects will receive a single subcutaneous injection of either SD-101 or placebo (PBS) in a ratio of 6:2.

Safety and tolerability will be evaluated by occurrence of adverse events, blood and urine laboratory tests, physical examination findings, vital signs , and electrocardiogram findings. Pharmacodynamics will be evaluated by levels of blood biomarkers and serum cytokines, and flow cytometric cell counts. Pharmacokinetics will be evaluated by levels of study drug in serum.
