Description of intervention(s) / exposure
Treatment: Drugs - Magrolimab
Treatment: Drugs - Nab-Paclitaxel
Treatment: Drugs - Paclitaxel
Treatment: Drugs - Sacituzumab Govitecan-hziy

Experimental: Safety Run-in Cohort 1: Magrolimab + Nab-Paclitaxel or Paclitaxel - Participants with untreated unresectable, locally advanced or metastatic TNBC whose tumors are not appropriate for immune checkpoint inhibitor therapy will receive the following:

* magrolimab in de-escalating doses to establish RP2D
* nab-paclitaxel or paclitaxel administered according to local guidelines.

Each cycle is 28 days.

Experimental: Phase 2 Cohort 1 Arm A: Magrolimab + Nab-Paclitaxel or Paclitaxel - Participants with mTNBC will receive the RP2D determined in the Safety Run-in cohort of magrolimab in combination with nab-paclitaxel or paclitaxel administered according to local guidelines.

Each cycle is 28 days.

Magrolimab will be continued until development of unacceptable toxicity that cannot be clinically managed by dose or schedule modifications. Nab-paclitaxel or paclitaxel will be continued until development of unacceptable toxicity.

Active comparator: Phase 2 Cohort 1 Arm B: Nab-Paclitaxel or Paclitaxel - Participants with mTNBC will receive nab-paclitaxel or paclitaxel administered according to local guidelines.

Each cycle is 28 days.

Nab-paclitaxel or paclitaxel will be continued until development of unacceptable toxicity.

Experimental: Safety Run-in Cohort 2: Magrolimab + Sacituzumab govitecan - Participants with unresectable, locally advanced or metastatic TNBC who have received at least 1 and no more than 2 prior lines of treatment in the unresectable, locally advanced or metastatic setting will receive the following:

* magrolimab in de-escalating doses to establish RP2D
* sacituzumab govitecan on Days 1 and 8

Each cycle is 21 days.

Experimental: Phase 2 Cohort 2: Magrolimab + Sacituzumab govitecan - Participants with mTNBC will receive the RP2D determined in the Safety Run-in cohort of magrolimab in combination with sacituzumab govitecan on Days 1 and 8. Each cycle is 21 days.

Magrolimab will be continued until development of unacceptable toxicity that cannot be clinically managed by dose or schedule modifications.sacituzumab govitecan will be continued until development of unacceptable toxicity.

Eligibility
Key inclusion criteria
Key Inclusion criteria:

* Adequate performance status, hematologic, renal and liver function.
* Measurable disease per RECIST v1.1
* Cohort 1: Individuals with previously untreated with systemic therapy for unresectable locally advanced or metastatic TNBC that are considered PD-L1 negative (as determined by an approved test according to local regulations).
* Cohort 2: Individuals with unresectable, locally advanced or metastatic breast cancer with a diagnosis of TNBC who have received at least 1 and no more than 2 prior lines of systemic therapy in the unresectable, locally advanced or metastatic setting. Individuals must have been previously treated with a taxane in any setting. Individuals with tumors that are considered positive for PD-L1 expression (as determined by an approved test according to local regulations) must have received an immune checkpoint inhibitor for a prior-line of treatment for unresectable locally advanced/metastatic TNBC.

Key exclusion criteria
* Positive serum pregnancy test or breastfeeding female.
* Active CNS disease. Individuals with asymptomatic and stable, treated CNS lesions (who have been off steroids, radiation and/or surgery and/or other CNS-directed therapy for at least 4 weeks) are allowed.
* RBC transfusion dependence, defined as requiring more than 2 units of packed RBC transfusions during the 4-week period prior to screening. Red blood cell transfusions are permitted during the screening period and prior to enrollment to meet the hemoglobin inclusion criteria.
* History of hemolytic anemia, autoimmune thrombocytopenia, or Evans syndrome in the last 3 months.

* Individuals who previously received topoisomerase I inhibitors or antibody-drug conjugates containing a topoisomerase inhibitor.
* High-dose systemic corticosteroids (= 20 mg of prednisone or its equivalent) are not allowed within 2 weeks of Cycle 1 Day 1.
* Have not recovered (ie, = Grade 2 is considered not recovered) from AEs due to a previously administered agent.

* Note: individuals with any grade of neuropathy, alopecia, hypo- or hyperthyroidism, or other endocrinopathies that are well controlled with hormone replacement are an exception to this criterion and will qualify for the study.
* Note: if individuals received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
