Date |
Amendment |
||||||
19 Aug 2010 |
The main purpose of this amendment is to update the enrollment scheme to state that data from 3 subjects in Group 2B is reviewed prior to enrolling neonates in Group 1. In addition, updates have been made in regard to prohibited and restricted use of treatments and provide additional supporting information to the rational pertaining to the enrollment of neonates. |
||||||
27 Dec 2010 |
The main purpose of this amendment is to update the stopping rules for individual subject discontinuation as well as criteria for when the study would be terminated. Other updates include the addition of language that the sponsor in conjunction with the investigators will review data at selected milestones throughout the study; the addition of recommended treatment guidelines for bleeding or suspected bleeding events, and language to allow dose adjustments to be implemented on the morning of Day 3. |
||||||
11 Dec 2011 |
The main purpose of this amendment is to update the Exclusion Criteria relating to positive urine screen for drugs of abuse for adolescents allowing medical monitor approval; allowance of concomitant medications during the study; Remove need for duplicate PD sample on Day 1, 0 hour, deletion of the statement that
plasma samples will be archived for potential metabolite analysis; deletion of the statement that subjects who receive placebo in any panel will be pooled into a single placebo group. Other updates include a change of the Study Directors and editorial updates. |
||||||
25 Jun 2012 |
The main purpose of this amendment is to update the Study Design section, whereas only Adolescents 12 years to <18 years (Cohorts 5A
& 5B) will continue to be enrolled in the study. Due to slow recruitment rate of younger age groups enrollment of subjects younger than 12 years was terminated after two (2) subjects from Cohort 4A were enrolled (Age Group 6 years to <12 years; Dose: 0.60 mg/m2). The number of total subjects in the study will change
from 60 to 12 (from Cohorts 5A & 5B). Reference to any other Cohorts, in the study design, has been removed. |
