tbo-filgrastim

An adverse event was defined as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. A treatment-emergent AE (TEAE) is an AE occurring during the timeframe. A non-TEAE is any AE not considered a TEAE. Severity was rated by the investigator using the NCI Common Terminology Criteria for Adverse Events (NCI-CTCAE) scale where 3=severe but not life-threatening, 4=life-threatening and 5=death. Relation of AE to treatment was determined by the investigator (related=reasonable possibility). Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical intervention to prevent the previously listed serious outcomes.

Serum chemistry tests included alkaline phosphatase, alanine aminotransferase (ALT), aspartate aminotransferase (AST), direct bilirubin, indirect bilirubin, total bilirubin, calcium, creatinine, gammaglutamyl transpeptidase (GGT), glucose, potassium, lactate dehydrogenase (LDH), phosphate, sodium and uric acid. Only tests with potentially clinically significant abnormal results are reported. ULN = upper limit of normal

Hematology tests included Basophils ABS (x 10\^9/L), Basophils (%), Eosinophils ABS (x 10\^9/L), Eosinophils (%), Hematocrit (%), Hemoglobin (g/L), Lymphocytes Absolute Count (ABS) (x 10\^9/L), Lymphocytes (%), Monocytes ABS (x 10\^9/L), Monocytes (%), Neutrophils ABS (x 10\^9/L), Neutrophils (%), Platelets (x 10\^9/L), Red Blood Cell (RBC) (x 10\^12/L), White Blood Cell (WBC) (x 10\^9/L). Only tests with potentially clinically significant abnormal results are reported. ULN = upper limit of normal

Vital sign tests included Pulse Rate (bpm), Systolic BP (mmHg), Diastolic BP (mmHg), Respiratory Rate (bpm), and Temperature (°C). Only tests with potentially clinically significant abnormal results are reported.

Triplicate 12-lead ECGs were conducted at screening, predose, 4 and 6 hours postdose on day 1 of tbo-filgrastim administration, and at the end-of-study visit. The ECGs were interpreted by both the investigator and a qualified physician at the central diagnostic center as normal, abnormal not clinically significant, or abnormal clinically significant. The following parameters were measured/derived for each ECG assessment: heart rate, PR interval, RR interval, QT interval, corrected QT interval according to Fridericia's formula (QTcF), corrected QT interval according to Bazett's formula (QTcB), QRS duration, and QRS axis. The count of participants with potentially clinically significant ECG findings is reported.

Physical examination was performed at screening and at the end-of-study visit. The following body systems were marked as normal or abnormal and if abnormal, whether clinically significant: Head, ears, eyes, nose and throat (HEENT), chest and lungs, heart, abdomen, skin, lymph nodes and neurological. Any physical examination finding that is judged by the investigator as a clinically significant change (worsening) compared with a baseline value were considered as an adverse event. Counts of participants with a negative shift from baseline in any of the body systems (including shifts from normal to abnormal, not clinically significant) are presented.

Using Local Tolerability Assessment Scale ranging from Pain severity 0 (Absent) to 3 (Spontaneously painful)

The investigator assessed spleen sonography findings as normal, abnormal not clinically significant, or abnormal clinically significant. Data representing counts of participants with a negative shift from baseline in spleen sonography findings (including shifts from normal to abnormal, not clinically significant) are presented.
