简要总结
CDX-301 is a protein that stimulates the growth of bone marrow stem cells and certain immune cells. This study is testing CDX-301 in healthy volunteers who will be monitored for safety and biological response for approximately one month or more.
详细描述
A total of seven cohorts of healthy volunteers are planned with doses of CDX-301 (rhuFlt3L) ranging between 1 and 75 μg/kg and dosing durations between 5 and 10 days.
Volunteers will be admitted to an inpatient unit during the Treatment Period. Blood samples will be collected periodically to assess the effect of CDX-301. Volunteers will be followed for safety for 28 days following the last dose. Any volunteer who develops anti-CDX-301 antibodies will be followed monthly until the antibody response is below the limit of detection. In general, the total duration of the study will be between approximately 33-38 days.

研究组 & 干预措施
CDX-301
CDX-301 (rhuFlt3L), administered to healthy patients.
干预措施: CDX-301 (Drug)
结局指标
主要结局
Number of reported adverse events
时间窗: Until day 28 of follow up.
The number of adverse events along with the results of vital sign measurements, physical examinations, and clinical laboratory tests will be used to determine the safety profile of CDX301.
次要结局
- Determination of PK profile of CDX301(Until day 28 of follow up or until resolution.)
- Immune system effects (eg: anti-CDX-301 antibody development, lymphoid cell populations, serum cytokines, and response to recall antigens and vaccination).(Until day 28 of follow up)
