Summary

This phase I/II trial studies the side effects and best dose of copanlisib and how well it works when given together with eribulin in treating patients with triple negative breast cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Copanlisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as eribulin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving copanlisib and eribulin may work better in treating advanced stage triple negative breast cancer compared to eribulin alone.

Description

PRIMARY OBJECTIVES:

I. To determine the safety, toxicity profile, dose limiting toxicity (DLT), maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of copanlisib hydrochloride (copanlisib) in combination with eribulin mesylate (eribulin) in metastatic triple negative breast cancer (TNBC). (Phase I) II. To compare progression free survival (PFS) between eribulin and eribulin plus copanlisib arms in patients with metastatic TNBC treated with prior taxane and anthracycline. (Phase II)

SECONDARY OBJECTIVES:

I. To determine the objective response rate (ORR) and clinical benefit rate (CBR) of the combination. (Phase I) II. To observe and record anti-tumor activity. (Phase I) III. To compare the ORR, CBR (complete response [CR]+partial response [PR]+stable disease [SD] >= 24 weeks) and safety of eribulin and eribulin plus copanlisib arms. (Phase II) IV. To compare the ORR, CBR, PFS of eribulin and eribulin plus copanlisib arms in patients with tumors harboring mutations in PIK3CA/ PTEN or with loss of PTEN expression by immunohistochemistry (IHC) on baseline tumor biopsy. (Phase II) V. To compare the ORR, CBR, PFS of eribulin and eribulin plus copanlisib arms in patients with tumors lacking PIK3CA/ PTEN pathway alterations. (Phase II) VI. To compare the ORR, CBR, PFS of eribulin and eribulin plus copanlisib arms in patients with tumors harboring loss of PTEN expression by IHC in pre-treatment metastatic site (in patients with available tissue from metastatic site). (Phase II) VII. To compare PTEN IHC results between paired archival primary tumor versus (vs.) baseline tumor biopsies. (Phase II) VIII. To assess targeted inhibition by copanlisib and eribulin by measuring treatment induced changes in phosphorylated (phospho)-AKT (T308), phospho-AKT (S473), phospho-histone H3, and inhibition of apoptosis (cleaved caspase 3) between post-treatment tumor (C2D1-2) versus baseline. (Phase II) IX. To compare the ORR, CBR, PFS of eribulin and eribulin plus copanlisib arms in patients with tumors harboring mutations in PIK3CA/PTEN by circulating tumor-derived deoxyribonucleic acid (ctDNA) at baseline, and potential changes over time. (Phase II)

EXPLORATORY OBJECTIVES:

I. To compare PTEN IHC results between paired baseline tumor biopsy versus at time of disease progression.

II. Assess baseline (pre-treatment) tumor tissue mutation or gene expression profiles to correlate treatment response.

III. Assess intrinsic and adaptive resistance mechanisms by analyzing pre and post treatment biopsies for gene expression and proteomic changes.

IV. Determine circulating tumor DNA (ctDNA) mutation profiles at baseline and changes in mutation profile and variant allele frequencies (VAFs) on cycle 2 day 1 (C2D1) and at disease progression compared to baseline to correlate with treatment response.

V. Assess circulating biomarkers predictive of treatment response. VI. Assess plasma and serum proteomics and metabolomics predictive of treatment response.

OUTLINE: This is a phase I dose-escalation study of copanlisib and eribulin followed by a phase II study. Patients are randomized to 1 of 2 groups.

GROUP I: Patients receive eribulin intravenously (IV) over 2 to 5 minutes on days 1 and 8 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

GROUP II: Patients receive copanlisib IV over 1 hour and eribulin IV over 2 to 5 minutes on days 1 and 8 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Patients in both groups also undergo a computed tomography (CT) scan and/or magnetic resonance imaging (MRI) at screening, cycle 3 day 1, and every 9 weeks thereafter. Patients also undergo a biopsy at baseline, cycle 2 day 1, and at time of disease progression and blood sample collection at baseline, cycle 2 day 1, every 9 weeks and at time of disease progression.

After completion of study treatment, patients are followed every 3 months for up to 36 months.

Patients must have progressed on at least one and not more than five prior chemotherapy regimens, including in the neoadjuvant, adjuvant, and metastatic settings. Prior chemotherapy in the neoadjuvant and/or adjuvant setting counts as one prior line. Prior endocrine therapy, anti-HER2 directed therapies, PARP inhibitors, immunotherapy alone, or other targeted therapy will not count as a prior therapy line, as long as the patient meets the eligibility criteria prior to enrollment. Immunotherapy combined with chemotherapy will be considered one line
All patients must agree to provide archival tumor material (most recent archival tumor tissue immediately prior to enrollment is strongly preferred) for research and must agree to undergo research tumor biopsy before treatment if presence of easily accessible lesions (judged by the treating physician). For patients with bone only disease, or patients without easily accessible lesions for the baseline research biopsy, availability of archival tumor material (2 x 4-5 micron section unstained slides, plus 15-20 x 10 micron section unstained slides or a tumor rich block) from previous breast cancer diagnosis or treatment is required for PTEN and PIK3CA analysis

Patients who are therapeutically treated with an agent such as warfarin or heparin will be allowed to participate provided that their medication dose and INR/PTT is stable
Prophylactic antiemetics may be administered according to standard practice. The routine use of standard antiemetics, including 5-HT3 blockers, such as granisetron, ondansetron, or an equivalent agent, is allowed as needed, as long as corrected QT (QTc) interval on baseline electrocardiogram (ECG) < 480 msec. The use of corticosteroids as antiemetics prior to copanlisib administration will not be allowed
For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial provided they are on a stable regimen of anti-retroviral therapy (ART) with no medications otherwise prohibited by this protocol (e.g. drug-drug interactions)
Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
Patients with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS)-directed therapy shows no evidence of progression. For patients with history of treated brain metastases, brain scans will be performed within 6 weeks of study enrollment. During study enrollment in the phase 2 portion of the study, brain MRI will be performed every 12 weeks or sooner if clinically-indicated in all patients with history of known brain metastases
For phase 1 portion of the study only: patients with new or progressive brain metastases (active brain metastases) or leptomeningeal disease are eligible if the treating physician determines that immediate CNS specific treatment is not required and is unlikely to be required during the first cycle of therapy. This is not allowed for phase 2 portion of the study
Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better.

Known mutation status for PIK3CA and PTEN from archival tumor tissue analysis
The effects of copanlisib on the developing human fetus are unknown. For this reason and because maternal toxicity, developmental toxicity and teratogenic effects have been observed in nonclinical studies and PI3K inhibitors as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation, and for 1 month after the last dose of study medication. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 3.5 months after completion of study treatment
Ability to understand and the willingness to sign a written informed consent document. Participants with impaired decision-making capacity (IDMC) who have a legally-authorized representative (LAR) and/or family member available will also be eligible

Patients who have had prior treatment with nitrosoureas or mitomycin C
Patients who have had prior treatment with eribulin
Patients who have had prior treatment with PI3K/mTOR/AKT pathway inhibitor
Clinically significant ECG abnormality, including prolonged corrected QT (QTc) interval > 480 msec or history of risk factors for Torsades de Pointes (TdP) (i.e. congestive heart failure, hypokalemia, hypomagnesemia, bradyarrhythmias, family history of long QT syndrome)

Known tumor AKT mutation from archival tumor tissue analysis
History of allergic reactions attributed to compounds of similar chemical or biologic composition to copanlisib, PI3K inhibitors, or other agents used in study
Copanlisib is primarily metabolized by CYP3A4. Therefore, the concomitant use of strong inhibitors of CYP3A4 (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, indinavir, nelfinavir and saquinavir), and strong inducers of CYP3A4 (e.g. rifampin, phenytoin, carbamazepine, phenobarbital, St. John's Wort) are not permitted from 14 days prior to enrollment until the end of the study. Other medications that are prohibited while on copanlisib treatment
Herbal medications/preparations (except for vitamins)
Anti-arrhythmic therapy other than beta blockers or digoxin
Systemic corticosteroid therapy at a daily dose higher than 15 mg prednisone or
equivalent is not permitted while on study. Previous corticosteroid therapy
Patients with uncontrolled intercurrent illness
must be stopped or reduced to the allowed dose at least 7 days prior to the
Patients with psychiatric illness/social situations that would limit compliance with study requirements
CT/MRI screening. If a patient is on chronic corticosteroid therapy
Patients with active, clinically serious infections > grade 2 (Common Terminology Criteria for Adverse Events Version 5.0 [CTCAEv5.0]) (viral, bacterial or fungal infection)
corticosteroids should be de-escalated to the maximum allowed dose before the

screening. Patients may be using topical or inhaled corticosteroids. Short-
term (up to 7 days) systemic corticosteroids above 15 mg prednisolone or
Patients with arterial or venous thrombotic or embolic events such as cerebrovascular accident (including transient ischemic attacks), deep vein thrombosis or pulmonary embolism within 3 months before the start of study medication
equivalent will be allowed for the management of acute conditions (e.g
Concurrent diagnosis of pheochromocytoma due to risk of hypertension with copanlisib
Proteinuria as estimated by urine protein/creatinine ratio > 3.5 g/g on random urine sample or grade >= 3 as assessed by 24-hour urine protein collection
Uncontrolled hypertension (defined as blood pressure >= 150/90 mm/Hg) despite optimal medical management (per investigator's opinion)
treatment non-infectious pneumonitis). The use of corticosteroids as
antiemetics prior to copanlisib administration will not be allowed
Patients with history of or current autoimmune disease
Patients with congenital QT prolongation
The patient has a personal history of any of the following conditions: syncope of cardiovascular etiology, ventricular arrhythmia of pathological origin (including, but not limited to, ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest
Patients with non-healing wound, ulcer, or bone fracture. Patients with compression or pathologic fractures that are stable in the opinion of the investigator may be enrolled, as long as the bone fracture is not felt to pose a high likelihood of treatment delay or difficulties in treatment adherence as per the judgement of the investigator
Pregnant women are excluded from this study because copanlisib is a PI3K inhibitor agent and eribulin is an anti-tubulin agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with copanlisib and eribulin, breastfeeding should be discontinued if the mother is treated with copanlisib and/or eribulin. These potential risks may also apply to other agents used in this study
