NCT04445844

Brief Summary

This is a phase 2 study to evaluate the safety and efficacy of the combination of INCMGA00012 and pelareorep and to see how well they work in treating patients with triple negative breast cancer that has spread to other parts of the body (metastatic). INCMGA00012 is a monoclonal antibody that works by attaching to the programmed cell death protein 1 (PD-1) and blocking this pathway, allowing the immune system to recognize and attack the cancer cells. Pelareorep is a type of virus called reovirus which occurs naturally and may break down cancer cells. Giving INCMGA00012 and pelareorep may slow the growth and spread of the cancer to another part of the body.

Outcome Measures

Primary Outcomes (2)

  • Objective response rate (ORR)

    Defined as the percentage of participants having an objective response (complete response \[CR\] or partial response \[PR\]), according to Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. The ORR of the drug will be assessed according to Simon's two stage design. The estimated ORR will be compared to the response rate specified in the null hypothesis (6%) using one-sided exact binomial test at type I error 5%. 95% confidence interval (C.I.) will be also reported.

    Within 8 weeks after completion of treatment

  • Incidence of adverse events

    Will be determined by the number, frequency, duration, and severity of adverse events (AEs) using Common Terminology Criteria for Adverse Events (CTCAE) v 5.0; laboratory tests and vital signs.

    Up to 2 years after completion of treatment

Secondary Outcomes (4)

  • Progression free survival (PFS)

    From the start of therapy until disease progression, or death due to any cause, assessed up to 2 years after completion of treatment

  • Overall survival (OS)

    From the start of therapy until death due to any cause, assessed up to 2 years after completion of treatment

  • Duration of Response (DOR)

    Up to 2 years after completion of treatment

  • Quality of life will be evaluated by European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-Core 30 (C30).

    Up to 2 years after completion of treatment

Other Outcomes (2)

  • Changes in PD-L1 expression

    Pre and post-treatment

  • T-cell receptor (TCR) sequencing

    Up to 2 years after completion of treatment

Study Arms (1)

Treatment (pelareorep, retifanlimab)

EXPERIMENTAL

Patients receive pelareorep IV over 60 minutes on days 1, 2, 15, and 16. Patients also receive INCMGA00012 IV over 60 minutes on day 3. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria

Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Metastatic or inoperable locally advanced, histologically documented triple negative breast cancer (TNBC) (negative expression of estrogen receptor \[ER\], progesterone receptor \[PR\] and human epidermal growth factor receptor 2 \[HER2\] immunohistochemistry \[IHC\] 0 or 1+, HER2 fluorescence in situ hybridization \[FISH\] negative if IHC 2+, per American Society of Clinical Oncology \[ASCO\] College of American Pathologists \[CAP\] guidelines)
  • Pre-menopausal and post-menopausal women who have received 1-2 prior lines of systemic therapy for metastatic triple negative breast cancer. Patients must have received at least one prior line of chemotherapy
  • Patients who have received adjuvant therapy for locally advanced triple negative breast cancer may be eligible for the study if they relapse with metastatic disease within 6 months since completion of neo-adjuvant/adjuvant systemic therapy. The adjuvant/neoadjuvant therapy will be considered as 1 line of therapy
  • Availability of tumor specimen for determination of PD-L1 and additional biomarker studies. Patient should be willing to undergo a pre-treatment biopsy as well as a biopsy after cycle 2 to evaluate the tumor microenvironment
