Symptomatic Skeletal Event Free Survival (SSE-FS)
Query!
Assessment method [1]
0
0
SSE-FS was defined as time (months) from randomization to the earliest of onset date of skeletal symptoms treated with external beam radiotherapy (EBRT), onset date of pathological bone fracture, onset date of spinal cord compression, procedure date of tumor-related orthopedic surgery, or death from any cause. Subjects who died without prior SSE and = 13 weeks after the last SSE assessment are censored at the last SSE assessment date. Subjects alive at the survival cut-off date are censored at the last date known to be alive. Subjects with multiple events are only counted for the category in which the first event occurred. If multiple SSE (component events) occur on the same date for 1 subject, the subject is only counted into 1 category in the order of: spinal cord compression \> bone fracture \> orthopedic surgery \> EBRT.

Time to Pain Progression
Query!
Assessment method [3]
0
0
Time to pain progression was defined as the interval from randomization to the first date a subject experienced pain progression, assessed by BPI-SF (see Baseline Characteristics) and defined as: an increase of 2 or more points in the average worst pain score (WPS) from baseline observed at 2 consecutive evaluations \>= 4 weeks apart or initiation of short- or long-acting opioid use for pain for subjects with WPS 0 at baseline; an increase of 2 or more points in the average WPS from baseline observed at 2 consecutive evaluations = 4 weeks apart and an average WPS of = 4 OR initiation of short- or long-acting opioid use for pain for subjects with WPS 1 to 3 at baseline. Subjects without pain progression at the end of study are censored at the last date known to have not progressed: the last evaluation date for pain scores or last visit when recorded opiate use, whichever is last. Subjects with no on-study assessment or no baseline assessment are censored at the date of randomization.

Number of Participants With Treatment-emergent Adverse Events
Query!
Assessment method [6]
0
0
An adverse event (AE) was any untoward medical occurrence (i.e., any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a participant in the study. A serious adverse event (SAE) was any untoward medical occurrence that at any dose was resulting in death, was lifethreatening, requires hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity. AEs or SAEs occurring after start of study treatment until the end of the treatment period were defined as treatment-emergent AEs (TEAEs) or serious TEAEs. Drug-related TEAEs or serious TEAEs were those with "reasonable causal relationship" to the study treatment decided by the investigators.

An adverse event (AE) was any untoward medical occurrence (i.e., any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a participant in the study.
