结局指标
主要结局
Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Treatment Emergent Serious Adverse Events (SAEs)
时间窗: From the start of study treatment through 30 days after the last dose of MEDI-573, up to 3.5 years
AEs were any unfavorable and unintended signs (including abnormal laboratory findings), symptoms, or diseases temporally associated with the use of MEDI-573, whether or not considered related to MEDI-573. A SAE was any AE that resulted in: death; inpatient hospitalization or prolongation of existing hospitalization; persistent or significant disability or incapacity; was life-threatening; was a congenital anomaly/birth defect in the offspring of a study participant; or was an important medical event that may not have resulted in death, threatened life, or required hospitalization and that, based on appropriate medical judgment, may have jeopardized the participant and may have required medical or surgical intervention to prevent one of the outcomes above. TEAEs were defined as AEs present at baseline that worsened in intensity after administration of MEDI-573, or events absent at baseline that emerged after administration of MEDI-573, up to 30 days after the last dose.
Number of Participants With Clinical Laboratory Abnormalities Reported as TEAEs
时间窗: From the start of study treatment through 30 days after the last dose of MEDI-573, up to 3.5 years
An abnormal laboratory finding that was judged by the investigator to be medically significant was reported as an AE. TEAEs were defined as events present at baseline that worsened in intensity after administration of MEDI-573, or events absent at baseline that emerged after administration of MEDI-573, for the period extending to 30 days after the last dose.
Number of Participants With Vital Signs and Physical Findings Abnormalities Reported as TEAEs
时间窗: From the start of study treatment through 30 days after the last dose of MEDI-573, up to 3.5 years
Vital signs and physical findings included parameters such as heart rate, blood pressure, temperature, and respiratory rate. TEAEs were defined as events present at baseline that worsened in intensity after administration of MEDI-573 or events absent at baseline that emerged after administration of MEDI-573, for the period extending to 30 days after the last dose.
Maximum Tolerated Dose (MTD) of MEDI-573
时间窗: Cycle 1 Day 1 through Cycle 1 Day 21
The MTD was defined as the highest dose that can be safely administered to participants and was determined by the number of participants in each cohort with a dose-limiting toxicity (DLT). The number and proportion of participants in each dose cohort and the number of participants with a DLT was presented using the total number of participants in the MTD Evaluable Population as the denominator. 2 participants from Cohorts 0.5 and 5 mg/kg QWk (1 in each cohort) did not complete the DLT period and therefore not evaluable for MTD.
Number of Participants With Dose-Limiting Toxicities (DLTs)
时间窗: Cycle 1 Day 1 through Cycle 1 Day 21
A DLT was defined as any grade greater than or equal to (\>=) 3 treatment-related non-hematologic toxicity that occurred during the DLT assessment period with the following exceptions: Grade less than (\<) 4 serum-high glucose (fasting) with duration of \< 24 hours; Grade 3 fever (in the absence of neutropenia) defined as \> 40.0 degree centigrade (°C) \[greater than (\>) 104.0°F\] that resolved to normal or baseline within 24 hours of treatment and was not considered an SAE; or Grade 3 rigors/chills that responded to optimal therapy; any Grade \>= 3 treatment-related hematologic toxicity that occurred during the DLT assessment period.
Optimal Biologically Effective Dose (OBED) of MEDI-573
时间窗: From the start of study treatment through 30 days after the last dose of MEDI-573, up to 3.5 years
The OBED was defined as the dose at which all circulating insulin-like growth factor (IGF)-1 and IGF-2 ligand was sequestered by MEDI-573.
