      Trial Summary

      This is a Phase Ib/II, open-label, multicenter, randomized umbrella study evaluating the efficacy and safety of multiple immunotherapy-based treatment combinations in patients with metastatic or inoperable locally advanced TNBC. The study will be performed in two stages. During Stage 1, two cohorts will be enrolled in parallel in this study: one cohort will consist of Programmed death-ligand 1 (PD-L1)-positive participants who have received no prior systemic therapy for metastatic or inoperable locally advanced triple-negative breast cancer (TNBC) (first-line [1L] PD-L1+ cohort), and one cohort will consist of participants who had disease progression during or following 1L treatment with chemotherapy (e.g., paclitaxel, nab-paclitaxel, carboplatin) and have not received cancer immunotherapy (CIT) (second-line [2L] CIT-naive cohort). In addition, participants in the 2L CIT-naive cohort who experience disease progression, loss of clinical benefit, or unacceptable toxicity during Stage 1 may be eligible to continue treatment with a different treatment combination (Stage 2), provided Stage 2 is open for enrollment.

      • Metastatic or inoperable locally advanced, histologically documented TNBC (absence of HER2, ER, and PR expression)
      • For the 1L PD L1+ cohort: no prior systemic treatment for metastatic or inoperable locally advanced TNBC
      • For the 2L CIT-naive cohort: Eligible for capecitabine monotherapy
      • For the 2L CIT-naive cohort: Radiologic/objective evidence of recurrence or disease progression after 1L treatment with chemotherapy, for a total of one line of therapy for inoperable locally advanced or metastatic breast cancer
      • Life expectancy =/> 3 months, as determined by the investigator
      • Tumor accessible for biopsy
      • Availability of a representative tumor specimen that is suitable for determination of PD-L1 and/or additional biomarker status via central testing
      • For the 1L PD L1+ cohort: Positive PD-L1 expression, defined as >/= 1% of the tumor area occupied by PD L1-expressing tumor-infiltrating immune cells of any intensity, as determined through use of the U.S. Food and Drug Administration-approved or CE-marked Ventana PD-L1 (SP142) Assay

      Inclusion Criteria for Stage 1 (both cohorts) and Stage 2 (2L CIT-naive cohort)

      • Measurable disease (at least one target lesion)
      • Adequate hematologic and end-organ function, laboratory test results, obtained within 14 days prior to initiation of study treatment.
      • Negative HIV test at screening
      • Negative hepatitis B surface antigen test
      • Negative total hepatitis B core antibody (HBcAb)
      • Negative hepatitis C virus (HCV) antibody test at screening
      • For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures and agreement to refrain from breastfeeding and donating eggs as outlined for each specific treatment arm
      • For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as outlined for each specific treatment arm

      Inclusion Criteria Stage 2 (2L CIT-naive cohort)

      • ECOG Performance Status of 0, 1, or 2
      • Patients randomly allocated to the control arm during Stage 1: ability to initiate Stage 2 treatment within 3 months after experiencing unacceptable toxicity, provided that Medical Monitor approval for entry into Stage 2 is obtained, or disease progression per RECIST v1.1 while receiving control treatment
      • Patients randomly allocated to an experimental arm during Stage 1: ability to initiate Stage 2 treatment within 3 months after experiencing unacceptable toxicity not related to atezolizumab, disease progression per RECIST v1.1, or loss of clinical benefit as determined by the investigator while receiving Stage 1 treatment
      • Availability of a tumor specimen from a biopsy performed upon discontinuation of Stage 1 (if deemed clinically feasible by the investigator)
