Immune modified RECIST will be done in the PEGCISGEMATEZO Arm only and requires confirmation of disease progression with an additional scan obtained no sooner than 28 days after the initial scan that showed progression. CR is defined as the disappearance of all target lesions. PR is defined as at least a 30% decrease in the sum of diameters of all target lesions, taking as reference the baseline sum of diameters, in the absence of CR. OS is defined as time from randomization to death at any time. Participant's tumor samples will be tested retrospectively for PD-L1 expression levels.

    PFS is defined as the time from randomization to radiological disease progression or death based on RECIST v1.1 for target lesions assessed by MRI/CT scans, as determined by independent radiologic review. PD is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum of diameters on or prior to the current assessment (including baseline). In addition to the relative increase of 20%, the sum of diameters must also demonstrate an absolute increase of ≥5 millimeters. OS is defined as time from randomization to death at any time.

  24. Expansion Portion: Number of Participants with AEs [ Time Frame: From date of randomization up to 30 days after the last dose of study treatment, (up to approximately 2 years 8 months) ]
    Safety will be assessed by monitoring and recording all adverse events (AEs), changes in clinical safety laboratory values (hematology, blood chemistry, coagulation, thyroid hormone levels, urinalysis results, viral serology, and PEGPH20 and ATEZO immunogenicity), 12-lead electrocardiogram (ECG) results, vital signs, physical examinations, medical history, concomitant medications, dose modifications (e.g. dose interruptions and delays) and Eastern Cooperative Oncology Group (ECOG) Performance Status. Severity of AEs will be graded by Investigators using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03.
