Number of Participants With Adverse Events
時間枠：From the start of study drug administration through 30 days after last dose of MEDI-575, up to 112 weeks
|
An adverse event (AE) is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug.
Treatment-emergent AEs (TEAEs) are events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug, for the period extending to 30 days after the last dose of study drug.
Participants were counted only once for each event and by the highest event severity, regardless of how many events the participant experienced.
The AEs were summarized using Medical Dictionary for Regulatory Activities (MedDRA) version 14.1.

Number of Participants With Serious Adverse Events
時間枠：From the start of study drug administration through 30 days after last dose of MEDI-575, up to 112 weeks

Maximum Tolerated Dose (MTD)
時間枠：From the start of study drug administration through 30 days after last dose of MEDI-575, up to 112 weeks
|
For the dose escalation phase, a minimum of 21 evaluable participants (3 participants each in Dose Cohorts 1 through 7) were required for this study if Dose Limiting Toxicities (DLTs) do not occur.
If a DLT does occur among the first 3 participants in a cohort, 3 additional participants were to be added to the cohort; 3 more participants were to be added to a cohort to determine the MTD if only 3 participants have been previously treated at that dose.
The MTD is the maximum dose at which no more than 1 out of 6 participants experienced a DLT.
A DLT is defined as any grade 3 or higher hematologic toxicity or any grade 3 or higher non-hematologic toxicity except grade 3 fever (in the absence of neutropenia) or grade 3 rigors/chills.

Percentage of Participants With Objective Response
時間枠：From study entry through the end of the study, up to 34 months
|
Objective response rate is defined as the proportion of participants with confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) guidelines.
Confirmed responses are those that persist on repeat imaging study at least 4 weeks after the initial documentation of response.
The CR is defined as disappearance of all target and non-target lesions, and normalization of tumor marker level.
The PR is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD.
|
From study entry through the end of the study, up to 34 months
|
|
Time to Response
|
Time to response was measured from the start of treatment with MEDI-575 to the first documentation of objective response (confirmed CR or PR).
The time to response is assessed only for the participants who have achieved the objective response.
|
|
|
Duration of Response
|
Duration of response is defined as the duration from the first documentation of objective response to the first documented disease progression.
Disease progression is defined according to RECIST guidelines (ie, at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions).
The duration of response was censored on the date of last tumor assessment documenting absence of disease progression for participants who have no documented progression prior to data cutoff, dropout, or the initiation of alternate anticancer treatment.
Duration of response was calculated for the subgroup of participants with an objective response.
|
|
|
Time to Progression
時間枠：Start of treatment with MEDI-575 until the documentation of disease progression, up to 24 months
|
Time to progression (TTP) is defined as time from the start of treatment with MEDI-575 until the documentation of disease progression.
Disease progression is defined according to RECIST guidelines (ie, at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions).
The TTP was censored on the date of last tumor assessment documenting absence of tumor progression for participants who have no documented progression prior to data cutoff, dropout, or the initiation of alternate anticancer treatment.
TTP was censored on the first date of treatment for the participants with no tumor assessments after the start of MEDI-575 treatment.

Progression-free Survival
時間枠：Start of treatment with MEDI-575 until the documentation of disease progression or death due to any cause whichever occurs first, up to 24 months
|
Progression-free survival (PFS) is defined as time from the start of treatment with MEDI-575 until the documentation of disease progression or death due to any cause, whichever occurred first.
Disease progression is defined according to RECIST guidelines (ie, at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions).
PFS was censored on the date of last tumor assessment documenting absence of tumor progression for participants who have no documented progression and were still alive prior to data cutoff, dropout, or the initiation of alternate anticancer treatment.
PFS was censored on the first date of treatment for the participants with no tumor assessments after the start of MEDI-575 treatment.
|
Start of treatment with MEDI-575 until the documentation of disease progression or death due to any cause whichever occurs first, up to 24 months

Overall Survival
時間枠：From the start of treatment with MEDI-575 until death or end of study, up to 33 months
