简要总结
This phase I/Ib trial tests the safety, side effects, best dose, and effectiveness of ASTX660 (tolinapant) in combination with eribulin mesylate (eribulin) in treating patients with triple negative breast cancer that cannot be removed by surgery (unresectable) or that has spread to nearby tissues or lymph nodes (locally advanced) or to other places in the body (metastatic). Tolinapant may stop the growth of tumor cells by blocking proteins, such as XIAP and cIAP1, needed for tumor cell survival. 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 tolinapant in combination with eribulin may be safe, tolerable, and/or effective in treating patients with unresectable, locally advanced, or metastatic triple negative breast cancer.

入选标准
- •Patients must have histologically or cytologically confirmed invasive breast carcinoma.
- •We limit the molecular subtype to triple negative (TNBC) and hormone receptor-low and Her2 negative (hormone receptor [HR]-low/Her2[-]) breast cancer. TNBC is defined as: HER2 expression 0 or 1+ on immunohistochemistry (IHC) or non-amplified (defined as HER2/CEP17 ratio < 2 or copy number < 6) on fluorescence in situ hybridization (FISH). If HER2 expression is 2+ on IHC, negative HER2 expression must be confirmed by FISH. Pathologic diagnosis of TNBC (negative HER2 status by cytogenetics, < 1% of cells stained positive for estrogen receptor [ER] by IHC, and < 1% of cells stained positive for progesterone receptor [PR] by IHC) (Allison et al., 2020, Wolff et al., 2013). HR-low/Her2(-) is defined as: HER2 expression 0 or 1+ on IHC or non-amplified (defined as HER2/CEP17 ratio < 2 or copy number < 6) on fluorescence in situ hybridization (FISH). If HER2 expression is 2+ on IHC, negative HER2 expression must be confirmed by FISH. 1-10% of cells stained positive for ER by IHC, and/or 1-10% of cells stained positive for PR by IHC) (Allison et al., 2020, Wolff et al., 2013)

- •Patients must have received at least 2 lines of systemic treatment for metastatic disease
- •Patients must have measurable disease according to the Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1) criteria
- •Age ≥ 18 years. Because no dosing or adverse event data are currently available on the use of ASTX660 (tolinapant) in combination with eribulin mesylate in patients < 18 years of age, children are excluded from this study

- •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)
- •For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
- •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 there is no evidence of progression for at least 4 weeks after central nervous system (CNS)-directed treatment, as ascertained by clinical examination and brain imaging (MRI or CT) during the screening period
- •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
- •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.

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
- •Patients must be willing to have biopsies for this study in order to be enrolled in the dose expansion
- •The effects of ASTX660 (tolinapant) on the developing human fetus are unknown. For this reason and because dual IAP antagonist agents as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential must agree to practice 1 highly effective contraceptive measure of birth control (with a failure rate of < 1% per year; preferably with low user dependency) during the study and for 6 months after the last dose of study treatment and must agree not to become pregnant for 6 months after completing treatment. Men with female partners of childbearing potential must agree to use a condom and advise their partners to practice 1 highly effective contraceptive measure of birth control (user dependent or with low user dependency) during the study and for at least 3 months after completing treatment, and must agree not to father a child while receiving study treatment and for at least 3 months after completing treatment

Previous corticosteroid therapy must be stopped or reduced to the allowed dose at least 7 days prior to the CT/MRI screening. If a patient is on chronic corticosteroid therapy, 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 equivalent will be allowed for the management of acute conditions (e.g., treatment non-infectious pneumonitis)
- •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
- •Patients with active, clinically serious infections > grade 2 (Common Terminology Criteria for Adverse Events [CTCAE] version [v]5.0) (viral, bacterial or fungal infection)
- •History of known pneumocystis jiroveci pneumonia (PJP) infection or documented non-infectious pneumonitis/interstitial lung disease (ILD)

- •Patients with uncontrolled intercurrent illness or any other significant condition(s) that would make participation in this protocol unreasonably hazardous
- •Pregnant women are excluded from this study because ASTX660 (tolinapant) and eribulin mesylate are anti-cancer agents 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 ASTX660 (tolinapant) and eribulin mesylate, breastfeeding should be discontinued until 2 weeks after the mother's last dose of study drugs
- •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 congenital long QT syndrome, bradyarrhythmias, or taking drugs known to prolong the QT interval
- •Patients unable to stop using any medication which is a moderate or strong CYP3A4 inhibitor or inducer within 2 weeks of the start of the study
