Summary

This phase Ib/II trial tests the safety and side effects of grapiprant and eribulin and whether they work to shrink tumors in patients with inflammatory breast cancer that has spread to other places in the body (metastatic). Grapiprant is an anti-inflammatory drug that may prevent tumor growth. Eribulin may block tumor cell growth by stopping tumor cell division. Giving grapiprant and eribulin together may help to control the disease.

Description

PRIMARY OBJECTIVE:

I. To determine the safety and efficacy of grapiprant and eribulin combination treatment for the patient with metastatic inflammatory breast cancer (mIBC).

SECONDARY OBJECTIVES:

I. To determine objective response rate (ORR), % of the patients who achieve complete response (CR) or partial response (PR).

II. To determine the time to progression (TTP) of the proposed treatment. III. To determine the duration of response of the proposed treatment. (Phase 2 only) IV. To determine the time to first response of the proposed treatment. (Phase 2 only) V. To determine progression-free survival (PFS) of the proposed treatment. VI. To determine the overall survival (OS) of the proposed treatment. VII. To investigate the predictive biomarker of the proposed treatment.

EXPLORATORY OBJECTIVE:

I. To evaluate the changes in the tumor microenvironment after the proposed treatment.

OUTLINE

Patients receive grapiprant orally (PO) twice daily (BID) on day 1-21 and eribulin mesylate intravenously (IV) over 5 minutes on days 1 and 8. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, then yearly for up to 5 years.

Eligibility

Yes No Not Sure

Inclusion Criteria

Male or female >= 18 years of age
Is willing and able to provide written informed consent for the trial
Has histological confirmation of breast carcinoma with a clinical diagnosis of IBC based on the presence of inflammatory changes in the involved breast, including diffuse erythema and edema (peau d'orange), with or without an underlying palpable mass involving the majority of the skin of the breast. Or the diagnosis confirmed by the MD Anderson IBC specialists. Pathological evidence of dermal lymphatic invasion should be noted but is not required for the diagnosis of IBC
Any prior treatments will be allowed except eribulin and/or any EP2/4 inhibitor
Has at least 2 weeks of untreated period from the previous treatment
Any receptor status for ER/PR and HER2. But for HER2+ type, must has failed trastuzumab, pertuzumab, and T-DM1 treatment
NOTE: HER2 positive status is defined as strongly positive (3+) staining score by immunohistochemistry (IHC), or gene amplification using fluorescence in situ hybridization (FISH), if performed. If IHC is equivocal (2+). HER2 negative status, which is determined by assays using IHC require negative (0 or 1+) staining score. If IHC is equivocal (2+) staining score
Has a measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST)
version (v)1.1 (only applies to phase II part)
NOTE: Measurable disease: Measurable lesions are defined as those that can be accurately measured in at least one-dimension (longest diameter to be recorded) as >= 20 mm by chest X-ray, >= 10 mm by computed tomography (CT) scan, >= 10 mm with calipers by clinical exam. Measurable malignant lymph nodes: To be considered pathologically enlarged and measurable, a lymph node must be >= 15mm in short axis when assessed by CT scan. Non-measurable disease: All other lesions (or sites of disease), including small lesions, are considered non-measurable. Bone lesions, leptomeningeal disease, ascites, pleural/pericardial effusions, lymphangitis, cutis/pulmonitis, inflammatory breast disease, and abdominal masses (not followed by CT or magnetic resonance imaging [MRI]) are considered non-measurable
Has a distant metastasis site or locoregional recurrence
Is willing to provide fresh tumor tissue via tumor biopsy before the first dose of the study drug only if participant has a disease can be be safely accessed through a CT-guided/ultrasound (US)-guided or percutaneous biopsy for multiple core biopsies judged by the investigator. If participant doesn't have a disease that can be safely accessed, they are still eligible
Performance status (PS) of 0 to 2 on the Eastern Cooperative Oncology Group (ECOG) performance scale
Absolute neutrophil count (ANC) >= 1,200 /mcL
Platelets >= 100,000 /mcL
Hemoglobin (Hgb) >= 9 g/dL
Total bilirubin =< 1.5 x upper limit of normal (ULN) (up to =< 3 x ULN for patients with liver metastasis)
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 2.5 x ULN (up to =< 5 x ULN for patients with liver metastasis)
Cockcroft-Gault glomerular filtration rate (GFR) (mL/min/1.73 m^2) >= 50
Left ventricular ejection fraction (LVEF) >= 50% by echocardiogram (ECHO) or multigated acquisition (MUGA) scan
Female patients must not be pregnant or breastfeeding and must be practicing a medically acceptable form of locally approved birth control, be sterile or post-menopausal. Male patients should be using a medically acceptable form of birth control during the trial or be sterile
Female patient: A female patient is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions
applies
Not a woman of childbearing potential (WOCBP) OR
A WOCBP agrees to follow the contraceptive guidance during the treatment period and at least 6 months after the last dose of trial intervention and must refrain from breastfeeding for at least 2 months after the last grapiprant treatment
WOCPB must have a negative urine pregnancy test no more than 7 days prior to starting treatment on-study
Male patients: A male patient must agree to use contraception during the
With CD4+ T-cell (CD4+) counts >= 350 cells/uL
treatment period and for at least 6 months after the last grapiuprant
Without a history of acquired immunodeficiency syndrome (AIDS)-defining opportunistic infections
treatment and refrain from donating sperm during this period
Patient with human immunodeficiency virus (HIV) including current or prior infection
would be included if
