End point description |
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. SAEs are defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; or other situations as per medical and scientific judgement of the Investigator. The analysis was performed on the Safety Set that included all participants who were enrolled and took at least one dose of study medication.

Change from Baseline in hematology parameter: Hematocrit | |||||||||||||||||||||||||||||||||||||||||||||||||||
End point description |
Blood samples were collected to analyze the hematology parameter: hematocrit. Baseline value was defined as the last non-missing value prior to the start date and time of the study medication (Day 1). Change from Baseline was calculated as the value at indicated time point minus the value at Baseline. Safety Set. Only those participants who were measured and analyzed (i.e., contributed data reported in the table) were included in the Overall Number of Participants Analyzed field. 'Number Analyzed' signifies participants evaluable for the specified time points (represented by n=X in category titles). 99999 indicates that standard deviation could not be calculated for single participant. 88888 indicates data is not available.

Date |
Amendment |
||||||
22 Jun 2022 |
Amendment 01: The primary rationale for Amendment 01 is to add the requirement for a temporary dose hold if the hemoglobin (Hgb) at Week 2 is greater than 12.5 g/dL. Additional changes are to provide further clarity of study requirements and to address regulatory feedback. |
||||||
18 Nov 2022 |
Amendment 02: The primary rationale for Amendment 02 is to include heart failure (HF) and esophageal/gastric erosions as adverse events of special interest (AESIs) following recent review of the clinical trial data in the adult daprodustat global development program. |
||||||
Interruptions (globally) |
|||||||
| Were there any global interruptions to the trial? Yes | |||||||
|
|||||||
Limitations and caveats |
|||||||
| Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||||||
| As the study was terminated early, only one age group 12 to <18 years of age was recruited as per the study design. As a result of low enrollment in study, no meaningful conclusions with respect to primary and secondary objectives could be reached. | |||||||
