ODN 1585 (50-500 μg, Injection into the tibialis anterior muscle, single) protects 20 to 90% of mice from sporozoite infection[1]. ODN 1585 (100 μg/dose, IP, twice weekly) is determined to be optimal for the induction of antitumor responses in several systems involving comparisons of 30, 100, and 300 μg/injection[2]. Animal Model: BALB/c ByJ mice (4- to 8-week-old, female, 6-18 mice in each group)[1] Dosage: 50, 100, 200, or 500 μg (in 50 μL of saline) Administration: Injection into the tibialis anterior muscle, single (at 7, 2, or 1 day(s) prior to sporozoite infection, on the day of infection, and/or at 1 day postinfection) Result: Protected 20 to 90% of mice from infection when the ODN 1585 was administered around the time of sporozoite challenge with doses of 50 to 500 μg. The highest level of protection (90%) resulted from administration of 200 μg of CpG ODN 1585 the day before challenge or 100 μg of CpG ODN 1585 on the day before and the day of challenge.
