入选标准
- •1. Age = 18 years
- •2. Life expectancy > 3 months.
- •3. ECOG Performance Status = 1
- •4. Metastatic breast cancer subjected previously treated with T-DM1, and/or T-DXd, and/or tucatinib-containing regimens. Subjects must have been previously treated with one (or more) of these regimens to be eligible. Subjects must have been treated with trastuzumab plus taxane.
- •Subjects who received prior pertuzumab, lapatinib, neratinib, margetuximab, and/or other available and accessible HER2-directed therapies or investigational therapies are eligible.
- •5. Presence of at least one measurable lesion per RECIST v 1.1 as determined by BICR.
- •6. A tumor block or formalin-fixed paraffin-embedded (FFPE) tissue from tumor biopsies as 10 pre-cut unstained slides must be collected for the HER2 status evaluation and biomarker analysis based on most recent tumor tissue sample. If insufficient tissue, a fresh tumor biopsy must be collected. All tumor tissue (including the pathology report and methods of pathology laboratory's tissue preparation/testing) needs to be sourced for central laboratory for HER2 testing.
- •7. Central laboratory-confirmed HER2-positive expression (estrogen receptor/progesterone receptor positive subjects may be enrolled if they are HER2-positive) according to 2018 American Society of Clinical Oncology – College of American Pathologists (ASCO-CAP) guidelines. See Laboratory Manual for details.
- •8. Subjects whose brain metastases have been treated may participate provided they show radiographic stability (defined as 1 brain MR image, obtained at least four weeks after treatment to the brain metastases, shows no evidence of intracranial progression). In addition, any neurologic symptoms (including seizures) that developed either as a result of the brain metastases or their treatment must have returned to baseline or resolved. Any steroids administered as part of this therapy must be completed at least three days prior to study medication. After approximately 20 such subjects [20% of the first 100 subjects] have been enrolled, subsequent subjects with any current or past history of brain metastases will be excluded.
- •9. Acute toxicities from any prior therapy, surgery, or radiotherapy must have resolved to Grade 0 or 1 as per the NCI-CTCAE v 5.0, except alopecia.
- •10. Adequate bone marrow function defined by absolute neutrophil count of = 1.5×109/L, platelet count of = 100.0×109/L, and hemoglobin of = 9.0 g/dL.
- •11. Adequate hepatic function, as defined by serum total bilirubin = 1.5 × ULN, serum aspartate aminotransferase and alanine aminotransferase = 2.5 × ULN. Subjects with known hepatic metastases or primary biliary cancer may have serum total bilirubin = 3.5 × ULN and transaminases = 5 × ULN.
- •12. Adequate renal function, defined as creatinine clearance = 30 mL/min, as calculated using the Cockcroft Gault equation: ([{140 -age in years} × {actual weight in kg}] divided by [{72 × serum creatinine in mg/dL}
- •multiplied by 0.85 if female]).
- •13. Adequate cardiac function as assessed by left ventricular ejection fraction = 50% or institutional lower limit of normal; cumulative anthracycline dose < 360 mg/m2 doxorubicin or equivalent.
- •14. Willing and able to understand and sign an informed consent inform and to comply with all aspects of the protocol.
- •15. Male and female subjects of reproductive/childbearing potential must agree to use a highly effective form of contraception or avoid intercourse during and upon completion of the study and for at least 6
排除标准
- •1. History of allergic reactions to any component of ARX788.
- •2. Prior history of interstitial lung disease, pneumonitis, or other clinically significant lung disease within 12 months prior to screening, with the exception of that directly attributable to the presence of lung metastases from their underlying cancer. Subjects with significant treatment-related lung injury, defined as any of the following, will be excluded:
- •a) Any prior history of drug-induced immune-mediated pneumonitis.
- •b) Prior history of radiation therapy to the chest of > 18 Gy with residual sequelae considered clinically significant by Investigator assessment.
- •c) Radiographic evidence of radiation fibrosis involving > 15% of the lung parenchyma associated with clinical symptoms.
- •3. Any active ocular infections until resolved or any chronic corneal disorder unless approved by Medical Monitor. Keratopathy of grade =1 due to prior treatment with anti-HER2 ADC or chemotherapy are allowed.
- •4. History of congestive heart failure, unstable angina pectoris, unstable atrial fibrillation, or cardiac arrhythmia within 12 months prior to enrollment. Medical history of myocardial infarction within 6 months prior to enrollment. Baseline QTc, averaged over 3 screening ECGs must be = 470 msec (females) or = 450 msec (males).
- •5. Grade 3 to 4 peripheral neuropathy (NCI-CTCAE v 5.0). Patients with Grade 2 neuropathy can be enrolled at investigator’s discretion.
- •6. Non-manageable electrolyte imbalances including hypokalemia, hypocalcemia, or hypomagnesemia (Grade 2 or greater based on NCI-CTCAE v 5.0).
- •7. Any uncontrollable intercurrent illness, infection (including subjects with active, symptomatic Covid-19 infections), or other conditions that could limit study compliance or interfere with assessments.
- •8. Exposure to any other investigational or commercial anticancer agents or therapies administered with the intention to treat malignancy within 2814 days before the first dose of ARX788. Anti-hormonal therapy may be administered up to 7 days prior to the first dose of ARX788.
- •9. Major surgical intervention within 21 days of the first dose of ARX788 or with ongoing post-operative complications.
- •10. Radiotherapy administered less than 21 days prior to the first dose of ARX788, or localized palliative radiotherapy administered less than 7 days prior to the first dose of ARX788, or radiotherapy-induced toxicity of Grade 2 or greater based on NCI-CTCAE v 5.0.
- •11. Pregnant or breast feeding.
- •12. Known active HCV, HBV, and/or HIV infection. HIV test is not required for the screening, unless required by the local Health Authorities.
