About this study
Official title: Innovative Combination Immunotherapy for Metastatic Triple Negative Breast Cancer (TNBC): A Multicenter, Multi-Arm Translational Breast Cancer Research Consortium Study
This phase II trial studies how well the combination of avelumab with liposomal doxorubicin with or without binimetinib, or the combination of avelumab with sacituzumab govitecan works in treating patients with triple negative breast cancer that is stage IV or is not able to be removed by surgery (unresectable) and has come back (recurrent). Immunotherapy with checkpoint inhibitors like avelumab require activation of the patient's immune system.
This trial includes a two week induction or lead-in of medications that can stimulate the immune system. It is our hope that this induction will improve the response to immunotherapy with avelumab. One treatment, sacituzumab Govitecan, is a monoclonal antibody called sacituzumab linked to a chemotherapy drug called SN-38. Sacituzumab govitecan is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of tumor cells, known as Tumor-associated calcium signal transducer 2 (TROP2) receptors, and delivers SN-38 to kill them. Another treatment, liposomal doxorubicin, is a form of the anticancer drug doxorubicin that is contained in very tiny, fat-like particles. It may have fewer side effects and work better than doxorubicin, and may enhance factors associated with immune response. The third medication is called binimetinib, which may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth, and may help activate the immune system. It is not yet known whether giving avelumab in combination with liposomal doxorubicin with or without binimetinib, or the combination of avelumab with sacituzumab govitecan will work better in treating patients with triple negative breast cancer.
Read the detailed description
OUTLINE: Patients are randomized to 1 of 3 active arms. The three previous study arms are closed to further accrual.
ARM A: Patients receive binimetinib orally (PO) twice daily (BID) for a lead-in period of 15 days in the absence of disease progression or unacceptable toxicity. Patients then receive binimetinib PO BID on days 1-28, avelumab intravenously (IV) over 60 minutes on days 1 and 15, and liposomal doxorubicin IV over 60 minutes on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive sacituzumab govitecan IV on days -15 for a lead-in period in the absence of disease progression or unacceptable toxicity. Patients then receive sacituzumab govitecan day 8 and day 15 of Cycle (C) 1; day 1, 8, and 21 of C2; day 1, 15 and 21 of C3; day 8 and 15 of C4, and the schedule continues with two weeks on, one week off for 21-day cycles which repeat in the absence of disease progression or unacceptable toxicity. Participants also receive avelumab IV over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM C: Patients receive liposomal doxorubicin IV over 60 minutes on day -15 for a lead-in period of 15 days in the absence of disease progression or unacceptable toxicity. Patients then receive liposomal doxorubicin IV over 60 minutes on day 15 and avelumab IV over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, then every 6 months for a minimum of 1 year. Participants will be followed every 3 months after experiencing disease progression to assess for survival/anti-cancer therapy status until death or 1 year after Cycle 1 Day 1.
PRIMARY OBJECTIVE:
- Anti-tumor effect of avelumab in combination with different therapeutic agents explored in the sub-protocols of the trial.
SECONDARY OBJECTIVES:
- Additional anti-tumor effects.
II. Safety and tolerability of avelumab in combination with different therapeutic agents explored in the sub-protocols of the trial.
III. Patient reported outcomes (PRO) between baseline and cycle 3 day 1 across arms.
IV. Longitudinal trends in PRO outcomes across treatment arms.
- Differences in PRO outcomes for patients who respond compared to those who do not respond.
CORRELATIVE OBJECTIVES:
- To determine the therapeutic predictive role of the following on clinical outcome as well as changes with induction therapy with either liposomal doxorubicin or targeted agents:
- PD-L1 expression and immune 'hot-spots'.
- Tumor infiltrating lymphocyte (TIL)s, and Cluster of differentiation 8 (CD8) and Cluster of differentiation 4 (CD4) positivity in TIL.
- Human leukocyte antigen (HLA)-A (MHC-I) and HLA-DR (MHC-II), FoxP3, OX40 and OX40L, phosphatase and tensin homologue (PTEN), and MYC expression.
- Number/levels of expressed predicted class I and class II neoantigens, central memory T-cells and T-cells.
- Expression of effector/regulatory immune gene, innate PD-1 resistance signature (IPRES), and B cell, T cell, and/or macrophage signatures.
- Basal or claudin-low molecular subtypes.
- T cell receptor (TCR) clonality in the tumor and peripheral blood.
- Genomic mutational burden.
II. To determine if circulating tumor deoxyribonucleic acid (DNA) (ctDNA) results will discriminate pseudo-progression from true progression.
III. To determine if certain genomic alterations detected in tumor tissue or ctDNA are potentially associated with resistance to the tested drug combinations.
IV. To correlate the composition of the pretreatment microbiome with response and secondary endpoints in each arm of the trial.
OUTLINE: Patients are randomized to 1 of 3 arms.
ARM A: Patients receive binimetinib orally (PO) twice daily (BID) for a lead-in period of 15 days in the absence of disease progression or unacceptable toxicity. Patients then receive binimetinib PO BID on days 1-28, avelumab intravenously (IV) over 60 minutes on days 1 and 15, and liposomal doxorubicin IV over 60 minutes on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive sacituzumab govitecan IV on days -15 and -8 as a lead-in period in the absence of disease progression or unacceptable toxicity. Patients then receive sacituzumab govitecan IV on days 1 and 8 and avelumab IV over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM C: Patients receive liposomal doxorubicin IV over 60 minutes on day -15. Patients then receive liposomal doxorubicin IV over 60 minutes on day 15 and every 4 weeks thereafter. Patients also receive avelumab IV over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, then every 6 months for a minimum of 1 year.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This phase II trial studies how well the combination of avelumab with liposomal doxorubicin with or without binimetinib, or the combination of avelumab with sacituzumab govitecan works in treating patients with triple negative breast cancer that is stage IV or is not able to be removed by surgery (unresectable) and has come back (recurrent). Immunotherapy with checkpoint inhibitors like avelumab require activation of the patient's immune system.
This trial includes a two week induction or lead-in of medications that can stimulate the immune system. It is our hope that this induction will improve the response to immunotherapy with avelumab. One treatment, sacituzumab Govitecan, is a monoclonal antibody called sacituzumab linked to a chemotherapy drug called SN-38. Sacituzumab govitecan is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of tumor cells, known as Tumor-associated calcium signal transducer 2 (TROP2) receptors, and delivers SN-38 to kill them. Another treatment, liposomal doxorubicin, is a form of the anticancer drug doxorubicin that is contained in very tiny, fat-like particles. It may have fewer side effects and work better than doxorubicin, and may enhance factors associated with immune response. The third medication is called binimetinib, which may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth, and may help activate the immune system. It is not yet known whether giving avelumab in combination with liposomal doxorubicin with or without binimetinib, or the combination of avelumab with sacituzumab govitecan will work better in treating patients with triple negative breast cancer.
Detailed description
OUTLINE: Patients are randomized to 1 of 3 active arms. The three previous study arms are closed to further accrual.
ARM A: Patients receive binimetinib orally (PO) twice daily (BID) for a lead-in period of 15 days in the absence of disease progression or unacceptable toxicity. Patients then receive binimetinib PO BID on days 1-28, avelumab intravenously (IV) over 60 minutes on days 1 and 15, and liposomal doxorubicin IV over 60 minutes on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive sacituzumab govitecan IV on days -15 for a lead-in period in the absence of disease progression or unacceptable toxicity. Patients then receive sacituzumab govitecan day 8 and day 15 of Cycle (C) 1; day 1, 8, and 21 of C2; day 1, 15 and 21 of C3; day 8 and 15 of C4, and the schedule continues with two weeks on, one week off for 21-day cycles which repeat in the absence of disease progression or unacceptable toxicity. Participants also receive avelumab IV over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM C: Patients receive liposomal doxorubicin IV over 60 minutes on day -15 for a lead-in period of 15 days in the absence of disease progression or unacceptable toxicity. Patients then receive liposomal doxorubicin IV over 60 minutes on day 15 and avelumab IV over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, then every 6 months for a minimum of 1 year. Participants will be followed every 3 months after experiencing disease progression to assess for survival/anti-cancer therapy status until death or 1 year after Cycle 1 Day 1.
PRIMARY OBJECTIVE:
- Anti-tumor effect of avelumab in combination with different therapeutic agents explored in the sub-protocols of the trial.
SECONDARY OBJECTIVES:
- Additional anti-tumor effects.
II. Safety and tolerability of avelumab in combination with different therapeutic agents explored in the sub-protocols of the trial.
III. Patient reported outcomes (PRO) between baseline and cycle 3 day 1 across arms.
IV. Longitudinal trends in PRO outcomes across treatment arms.
- Differences in PRO outcomes for patients who respond compared to those who do not respond.
CORRELATIVE OBJECTIVES:
- To determine the therapeutic predictive role of the following on clinical outcome as well as changes with induction therapy with either liposomal doxorubicin or targeted agents:
- PD-L1 expression and immune 'hot-spots'.
- Tumor infiltrating lymphocyte (TIL)s, and Cluster of differentiation 8 (CD8) and Cluster of differentiation 4 (CD4) positivity in TIL.
- Human leukocyte antigen (HLA)-A (MHC-I) and HLA-DR (MHC-II), FoxP3, OX40 and OX40L, phosphatase and tensin homologue (PTEN), and MYC expression.
- Number/levels of expressed predicted class I and class II neoantigens, central memory T-cells and T-cells.
- Expression of effector/regulatory immune gene, innate PD-1 resistance signature (IPRES), and B cell, T cell, and/or macrophage signatures.
- Basal or claudin-low molecular subtypes.
- T cell receptor (TCR) clonality in the tumor and peripheral blood.
- Genomic mutational burden.
II. To determine if circulating tumor deoxyribonucleic acid (DNA) (ctDNA) results will discriminate pseudo-progression from true progression.
III. To determine if certain genomic alterations detected in tumor tissue or ctDNA are potentially associated with resistance to the tested drug combinations.
IV. To correlate the composition of the pretreatment microbiome with response and secondary endpoints in each arm of the trial.
OUTLINE: Patients are randomized to 1 of 3 arms.
ARM A: Patients receive binimetinib orally (PO) twice daily (BID) for a lead-in period of 15 days in the absence of disease progression or unacceptable toxicity. Patients then receive binimetinib PO BID on days 1-28, avelumab intravenously (IV) over 60 minutes on days 1 and 15, and liposomal doxorubicin IV over 60 minutes on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive sacituzumab govitecan IV on days -15 and -8 as a lead-in period in the absence of disease progression or unacceptable toxicity. Patients then receive sacituzumab govitecan IV on days 1 and 8 and avelumab IV over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM C: Patients receive liposomal doxorubicin IV over 60 minutes on day -15. Patients then receive liposomal doxorubicin IV over 60 minutes on day 15 and every 4 weeks thereafter. Patients also receive avelumab IV over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, then every 6 months for a minimum of 1 year.

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Best Overall Response Rate (BORR) (time frame: From treatment initiation until disease progression, an estimated average of 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Apr 2026.
