简要总结
This study will examine the safety of ascending doses of AB-SA01 when topically applied to intact skin of healthy adults.
详细描述
AB-SA01 consists of three bacteriophages (viruses) that target Staphylococcus aureus bacteria.
The safety of AB-SA01 will be assessed when topically administered once daily to the volar aspect of the forearm at a dose of 10^8 plaque forming units (PFU) per phage for 3 consecutive days, and then at a dose of 10^9 plaque forming units (PFU) per phage for 3 consecutive days. Both AB-SA01 and placebo will be administered to each subject to provide his/her own control for evaluation of skin reactions. The right or left placement of the placebo will be randomized and double-blinded.

- •Acute or chronic, clinically significant pulmonary, cardiovascular, neurologic, hepatic, or renal functional abnormality as determined by medical history, physical examination, or laboratory screening tests
- •Screening lab results with any Grade 2 or higher abnormality or clinically significant Grade 1 abnormality, as determined by the Common Terminology Criteria for Adverse Events (CTCAE).
- •Administration of immunoglobulins and/or any blood products within the 3 months preceding the first study treatment or planned administration during the study period
