Basic Information

Brief Summary

This phase I trial is to find out the best dose, possible benefits and/or side effects of NHS-IL12 given together with bintrafusp alfa and radiation therapy in treating patients with hormone receptor positive, HER2 negative breast cancer that has spread to other places in the body (metastatic). Immunotherapy with NHS-IL12, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Immunotherapy with bintrafusp alfa, a bifunctional fusion protein composed of the monoclonal antibody avelumab and TGF-beta, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving NHS-IL12, bintrafusp alfa, and radiation therapy may kill more tumor cells.

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate the safety and tolerability of bintrafusp alfa (M7824) in combination with immunocytokine NHS-IL12 (NHS-IL-12) and radiation therapy in patients with metastatic hormone receptor positive (HR+)/HER2- breast cancer.

II. To determine the recommended phase II dose (RP2D) of NHS-IL-12 in combination with M7824 and radiation therapy in patients with metastatic HR+/HER2- breast cancer.

SECONDARY OBJECTIVES:

I. To assess immunologic/molecular responses, specifically percent (%) change in tumor infiltrating lymphocytes (TIL) pre and post therapy to M7824 in combination with NHS-IL-12 and radiation therapy in patients with HR+/HER2- metastatic breast cancer.

II. To explore preliminary progression free survival (PFS) and overall survival (OS) to power future definitive trial.

III. To evaluate the in-field and abscopal effect of treatment with M7824 in combination with NHS-IL-12 and radiation therapy.

EXPLORATORY OBJECTIVES:

I. To characterize circulating immune cell populations and cytokine profiles in tumor and circulation following treatment with M7824.

II. To conduct tissue-based ribonucleic acid sequencing (RNAseq), RNA scope, whole exome sequencing (WES) targeted sequencing.

III. To correlate dosimetry to response (assessed by degree of radiation fibrosis).

IV. To evaluate the pharmacokinetics of NHS-IL-12 in combination with M7824.

OUTLINE: This is a dose-escalation study of immunocytokine NHS-IL12.

Patients receive bintrafusp alfa intravenously (IV) over 1 hour on days 1 and 14 and immunocytokine NHS-IL12 subcutaneously (SC) on day 14. Beginning on day 14 of cycle 1, patients undergo radiation therapy once daily (QD) for up to 4 days. 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.

Eligibility Criteria

Inclusion Criteria

• Is willing and able to provide written informed consent for the trial and has signed the appropriate written informed consent form, approved by the investigator's Institutional Review Board (IRB)/Independent Ethics Committee (IEC), prior to the performance of any trial activities
• Is age >= 18 years at time of study entry
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
• Women of childbearing potential must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 8 weeks after the last dose of investigational product in such a manner that the risk of pregnancy is minimized. Men on study also must be using contraception. Women of childbearing potential (WOCBP) are women who have not been postmenopausal greater than 1 year or undergone a hysterectomy or bilateral oophorectomy
• Has confirmed HR+ and HER2 negative breast cancer with known metastatic disease. Eligible patients must have estrogen receptor (ER) and/or progesterone (PR) expression 10% or greater by immunohistochemistry (IHC). HER2 negative or nonamplified is determined by the current American Society of Clinical Oncology- College of American Pathologists (ASCO-CAP) criteria which are as follows: HER2 testing by IHC as 0 or 1+. If HER2 is 2+, ISH (in situ hybridization) must be performed. HER2 is positive if:

• IHC 3+ based on circumferential membrane staining that is

• Complete, intense
• ISH positive based on:

• Single-probe average HER2 copy number >= 6.0 signals/cell
• Dual-probe HER2/CEP17 ratio >= 2.0 with an average HER2 copy number >= 4.0 signals/cell
• Dual-probe HER2/CEP17 ratio >= 2.0 with an average HER2 copy number < 4.0 signals/cell
• Dual-probe HER2/CEP17 ratio < 2.0 with an average HER2 copy number >= 6.0 signals/cell
• Has at least 2 identified sites of metastatic disease. This can include areas of metastatic disease to the bone, but one additional of the sites of metastatic disease must be amenable to biopsy
• Has measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) criteria
