Primary outcomes

  1. Percentage of Participants With an Objective Response

    Time frame: Disease assessments were performed at weeks 1, 7, 13, 19, and approximately every 9 weeks thereafter. The mean actual follow-up time from randomization was 4.7 and 5.0 months for ABP 215 and bevacizumab, respectively.

    Tumor assessments were performed by central, independent, blinded radiologists according to the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 using computed tomography (CT) or magnetic resonance imaging (MRI) scans of the chest and abdomen. Objective response is defined as a best overall response of partial response (PR) or complete response (CR) as defined by RECIST v1.1. All participants who did not meet the criteria for CR or PR by the end of the study were considered non-responders.

    CR: Disappearance of all target and non-target lesions and no new lesions. Any pathological lymph nodes must be reduced in short axis to < 10 mm.

    PR: Disappearance of all target lesions with persistence of one or more non-target lesion(s) and/or maintenance of tumor marker level above the normal limits, and no new lesions, or, at least a 30% decrease in the sum of diameters of target lesions, with no progression of existing non-target lesions and no new lesions.

Secondary outcomes

  1. Duration of Response

    Time frame: Disease assessments were performed at weeks 1, 7, 13, 19, and approximately every 9 weeks thereafter. The mean actual follow-up time from randomization was 4.7 and 5.0 months for ABP 215 and bevacizumab, respectively.

    Duration of response (DOR) was calculated as the time from the first objective response (PR or CR) to disease progression per RECIST v1.1 based on the central, independent, blinded radiologists' review.

    DOR was only calculated for participants with an objective response. For responders not meeting the criterion for progression by the end of the study, DOR was censored at the date of the last evaluable tumor assessment.

    Progressive Disease was defined as at least a 20% increase in the sum of diameters of target lesions with an absolute increase of at least 5 mm, or, unequivocal progression of existing non-target lesions, or any new lesions.

  2. Progression-free Survival

    Time frame: From randomization until the end of study; The mean actual follow-up time from randomization was 4.7 and 5.0 months for ABP 215 and bevacizumab, respectively.

    Progression-free survival (PFS) was defined as the time from the randomization date to the date of disease progression using RECIST v1.1 based on the central, independent, blinded radiologists' review, or death. Participants who were alive and did not meet the criteria for progression by the end of the study were censored at their last evaluable disease assessment date. Participants with no evaluable tumor assessments after randomization who did not die by the end of the study were censored on the randomization date.

    Progressive Disease was defined as at least a 20% increase in the sum of diameters of target lesions with an absolute increase of at least 5 mm, or, unequivocal progression of existing non-target lesions, or any new lesions.

  3. Number of Participants With Adverse Events

    Time frame: up to 19 weeks

    Adverse events (AEs) were graded for severity according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4, and according to the following scale: Grade 1 = Mild, Grade 2 = Moderate, Grade 3 = Severe, Grade 4 = Life-threatening and Grade 5 = Death due to AE.

    A serious adverse event (SAE) is defined as an AE that meets at least 1 of the following serious criteria:

    • fatal
    • life-threatening
    • required inpatient hospitalization or prolongation of existing hospitalization
    • resulted in persistent or significant disability/incapacity
    • congenital anomaly/birth defect
    • other medically important serious event

  4. Number of Participants Who Developed Anti-drug Antibodies

    Time frame: 44 weeks (6 months after end of treatment)

    Two validated assays were used to detect the presence of anti-ABP 215 antibodies. Samples were first tested in an electrochemiluminescence (ECL)- based bridging immunoassay to detect antibodies capable of binding to ABP 215 (Binding Antibody Assay). Samples confirmed to be positive for binding antibodies were subsequently tested in a non-cell based target binding assay to determine neutralizing activity against ABP 215 (Neutralizing Antibody Assay). If a post-dose sample was positive for binding antibodies and demonstrated neutralizing activity at the same time point, the sample was defined as positive for neutralizing antibodies.

  5. Overall Survival

    Time frame: From randomization until the end of study; The mean actual follow-up time from randomization was 4.7 and 5.0 months for ABP 215 and bevacizumab, respectively.

    Overall survival (OS) was defined as the time from the randomization date to date of death. Participants alive at the end of study were censored at the last date known to be alive, derived from dates collected within the study that implied a participant was alive.

    Participants were followed for survival status during the treatment phase and thereafter every 9 weeks until the end of the clinical study, consent was withdrawn, they were lost to follow-up, died, or had proscribed therapy (eg, commercial bevacizumab, non-study anti-cancer treatment).
