Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Measuring the effect of adagloxad simolenin (OBI-822)/OBI-821 treatment on improving invasive disease free survival (IDFS) in the study population. [ Time Frame: 5 years ]
    The outcome measure of the study is IDFS, defined by the STEEP system as the first occurrence of the time from the date of randomization to the date of first invasive disease recurrence (local, regional or distant), the date of secondary primary invasive cancer (breast or not), or the date of death from any cause.


Secondary Outcome Measures :
  1. Measuring the impact of adagloxad simolenin (OBI-822)/OBI-821 treatment in the study population on Overall Survival (OS). [ Time Frame: 7 years ]
    OS is defined as the time from randomization to date of death from any cause

  2. Measuring the impact of adagloxad simolenin (OBI-822)/OBI-821 treatment in the study population on Quality of Life (QoL). [ Time Frame: 7 years ]

    QoL defined as time to definitive deterioration in Health-related Quality of Life (HRQOL) using the global health status/QoL scale from European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30) and the European Quality of Life 5 Dimensions 5 Levels (EQ-5D-5L). QoL baseline established at randomization.

    Definitive deterioration defined as a 5% worsening relative to baseline in the HRQOL scale score from EORTC QLQ-C30 questionnaires with no subsequent improvement above threshold, scored with the EORTC QLQ-C30 v3.0 Scoring Manual. The EQ-5D-5L questionnaire assesses mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, rated by the patient. It is a standardized measure of health status to provide a simple, generic measure of health for clinical and economic appraisal. 28 questions have a 4 point scale: not at all(1) to very much(4). 2 questions have a 7-point scale: very poor (1) to excellent(7).


  3. Measuring the impact of adagloxad simolenin (OBI-822)/OBI-821 treatment in the study population on Breast cancer-free interval (BCFI). [ Time Frame: 7 years ]
    BCFI is defined by the STEEP system as the first occurrence of the time from the date of randomization to the date of the first invasive disease recurrence (local, regional or distant), the date of ductal carcinoma in situ (ipsilateral or contralateral), or the date of death from breast cancer

  4. Measuring the impact of adagloxad simolenin (OBI-822)/OBI-821 treatment in the study population on Distant disease-free survival (DDFS). [ Time Frame: 7 years ]
    DDFS is defined by the STEEP system as the first occurrence of the time from the date of randomization to the date of the first distant disease recurrence, the date of the second primary invasive cancer (non-breast), or the date of death from any cause

  5. Incidence and severity of adverse events (AEs) [Time Frame: AEs will be noted as it occurs, with a timeframe from beginning of randomization to 4 weeks after last dose of study treatment.] [ Time Frame: 2 years ]
    Adverse Events will be graded and recorded by investigators per National Cancer Institute-Common Terminology Criteria for Adverse Events version 5.0 (NCI-CTCAE v5.0).

Criteria

Inclusion Criteria:

  • Documented radiographic and histopathologic confirmed primary localized invasive breast cancer.

  • HER2/neu negative will be defined as one of the following criteria:

    • IHC 0 or 1+
    • Single-probe average HER2 gene copy number of <6 signals/nucleus

  • Globo H IHC H-score ≥15 from the residual primary site/or lymph node (if primary site is not available) tumor obtained at time of definitive surgery. Globo H expression will be determined during pre-screening by Central lab. Instructions for submission of slides/tumor tissue blocks are provided in the protocol and study Lab Manual.
  • No evidence of metastatic disease in chest, abdomen and pelvis by CT or other adequate imagining during the Screening Phase. Imaging within 3 months prior to randomization is acceptable as baseline scan. Bone scans and imaging of the brain at screening is optional, and should be symptom directed.
