Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Treatment-emergent Adverse Events (TEAEs)	An adverse event (AE) is defined as any untoward medical occurrence in a clinical trial subject including worsening of a pre-existing medical condition, and not necessarily having a causal relationship with study treatment. A treatment-emergent AE is an event that occurred after the initiation of study drug or was already present prior to the initiation of study drug but worsened in either intensity or frequency after the initiation of study drug.; The investigator assessed whether each AE was possibly related to the study drug.; A serious adverse event is defined as an AE that met at least 1 of the following serious criteria: fatal,; life threatening,; required in-patient hospitalization or prolongation of existing hospitalization,; resulted in persistent or significant disability/incapacity,; congenital anomaly/birth defect, and/or; other significant medical hazard.	From first dose of study drug until the end of study; median (min, max) duration was 70 days (14, 223)
Primary	Percentage of Participants Who Achieved a CDAI Response	CDAI response is defined as a reduction from baseline in CDAI score of = 100 points.; The CDAI measures the severity of active disease using 8 disease variables (stool frequency, severity of abdominal pain, degree of general well-being, presence or absence of extra-intestinal manifestations or fistula, use or non-use of antidiarrheal agents, presence or absence of an abdominal mass, hematocrit, and body weight). The CDAI score is calculated by summing weighted scores for each item. CDAI scores range from 0 to 600, with higher scores indicating greater disease activity.	Baseline of the parent study and weeks 2, 4, 6, 8, 10, 12, 16, and 20
Primary	Percentage of Participants Who Achieved Clinical Remission	Clinical remission is defined by a CDAI score of = 150 points. The CDAI measures the severity of active disease using 8 disease variables (stool frequency, severity of abdominal pain, degree of general well-being, presence or absence of extra-intestinal manifestations or fistula, use or non-use of antidiarrheal agents, presence or absence of an abdominal mass, hematocrit, and body weight). The CDAI score is calculated by summing weighted scores for each item. CDAI scores range from 0 to 600, with higher scores indicating greater disease activity.	Weeks 2, 4, 6, 8, 10, 12, 16, and 20
Secondary	CDAI Score Over Time	The CDAI measures the severity of active disease using 8 disease variables (stool frequency, severity of abdominal pain, degree of general well-being, presence or absence of extra-intestinal manifestations or fistula, use or non-use of antidiarrheal agents, presence or absence of an abdominal mass, hematocrit, and body weight). The CDAI score is calculated by summing weighted scores for each item. CDAI scores range from 0 to 600, with higher scores indicating greater disease activity.	Weeks 2, 4, 6, 8, 10, 12, 16, and 20
Secondary	Change From Baseline in CDAI Score Over Time	The CDAI measures the severity of active disease using 8 disease variables (stool frequency, severity of abdominal pain, degree of general well-being, presence or absence of extra-intestinal manifestations or fistula, use or non-use of antidiarrheal agents, presence or absence of an abdominal mass, hematocrit, and body weight). The CDAI score is calculated by summing weighted scores for each item. CDAI scores range from 0 to 600, with higher scores indicating greater disease activity.	Baseline of the parent study and Weeks 2, 4, 6, 8, 10, 12, 16, and 20
Secondary	Number of Participants Who Developed Anti-brodalumab Binding Antibodies	Binding antibodies to brodalumab were detected using an anti-brodalumab immunoassay.	Blood samples were collected at study entry, week 4, 24 and at last visit (maximum time on study was 32 weeks).
Secondary	Change From Baseline in C-reactive Protein (CRP) Levels Over Time		Baseline of the parent study and Weeks 2, 4, 6, 8, 10, 12, 16, and 20
