Number of Participants With Treatment-emergent Adverse Events (TEAEs)
Tidsramme: Day 1 through Day 71
|
An adverse event (AE) was any untoward medical occurrence in a participant who had been administered a pharmaceutical product. An AE did not necessarily have a causal relationship with the product and therefore could be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a pharmaceutical product. An AE could arise with any use, route of administration, formulation, dose (including an overdose), or when used in combination with another pharmaceutical product. A TEAE was an AE with an onset date/time after the first infusion of ANX005 until the end of the study. A summary of serious and all other non-serious adverse events regardless of causality is located in the Adverse Events module. |
Day 1 through Day 71
|
|
Maximum Change From Baseline in Hemoglobin Levels
Tidsramme: Baseline up to Day 71
|
Maximum change from Baseline was calculated as the maximum post-Baseline value observed up to Day 71 minus the Baseline value.
Baseline was defined as the last non-missing observation recorded before the first dose of ANX005.
|
Baseline up to Day 71
|
|
Change From Baseline in Lactate Dehydrogenase Levels at Day 71
Tidsramme: Baseline, Day 71
|
Change from Baseline was calculated as the post-Baseline value at Day 71 minus the Baseline value.
Baseline was defined as the last non-missing observation recorded before the first dose of ANX005.
|
Baseline, Day 71
|
|
Change From Baseline in Percentage of Reticulocytes/Total Cells Count at Day 71
Tidsramme: Baseline, Day 71
|
Change from Baseline was calculated as the post-Baseline value at Day 71 minus the Baseline value. Baseline was defined as the last non-missing observation recorded before the first dose of ANX005. |
