Single Ascending DosesEXPERIMENTALEnrollment of patients in two age groups. A Sentinel group of 2 patients aged 13 to 18 years of age, inclusive, and an expanded group of 2 patients 2 to 12 years of age to receive single doses. There will be an option to dose up to 6 additional patients at each dose level and an option to expand the maximum tolerated dose level with 5 additional patients.
Multiple Ascending DosesEXPERIMENTALEnrollment of patients in two age groups. A Sentinel group of 2 patients aged 13 to 18 years of age, inclusive, and an expanded group of 2 patients 2 to 12 years of age to receive multiple doses. There will be an option to dose up to 6 additional patients at each dose level and an option to expand the maximum tolerated dose level with 10 additional patients.
