You may be eligible if
1. Subjects must have histologically documented, metastatic, HER2-negative breast cancer that has progressed after two prior lines of therapy (including adjuvant therapy if progressed within the last 12 months, and aromatase inhibitors will be considered a line of therapy). Subjects with HR+ disease can have prior CDK4/6 inhibitors and subjects with BRCAm disease may have prior PARPi therapy. HER2 positivity is defined by standard of care fluorescence in situ hybridization (FISH) and/or 3+ staining by immunohistochemistory (IHC) according to the American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) Clinical Practice Guideline Focused Update.
2. A minimum of 2 weeks or 5 half-lives (whichever is longer) will be required from any prior therapy for mBC, including chemotherapy, immunotherapy and/or radiation therapy.
3. Subjects must have measurable disease as per RECIST v1.1.
4. Females, age 18 years or older.
5. ECOG performance status ≤ 2.
6. Subjects with previously treated brain metastases (surgery, whole or stereotactic brain radiation) are allowed provided the lesions have been stable for at least 4 weeks and the subject is off steroids for at least 7 days prior to first dose of study treatment, and any neurologic symptoms have returned to baseline (without evidence of progression by imaging using the identical imaging modality for each assessment, either MRI or CT scan).
7. Subjects with brain metastases should not require use of enzyme-inducing antiepileptic drugs (eg, carbamazepine, phenytoin, or phenobarbital) within 14 days before first dose of study treatment and during study. Use of newer antiepileptics that do not produce enzyme induction drug-drug interactions is allowed.
8. Subjects must have normal organ and marrow function as defined below:
* absolute neutrophil count ≥ 1.5 x 109/L without growth factor support in the last 7 days
* platelets ≥ 100 x 109/L without growth factor support in the last 7 days
* hemoglobin ≥ 9 g/dL and no blood transfusion within 4 weeks
* total bilirubin ≤ 1.5 x the upper limit of normal (ULN) (unless Gilbert's Disease)
* AST(SGOT)/ALT(SGPT) ≤ 2.5 x ULN (≤ 5 x ULN if liver metastases)
* creatinine clearance ≥ 60 mL/min (calculated using the Cockroft-Gault formula) for subjects with creatinine levels above institutional normal
9. Patients of childbearing potential have a negative serum pregnancy test within 72 hours prior to the first dose of study medication. Non-childbearing potential is defined as (by other than medical reasons):
* 45 years of age or older and has not had menses for \> 1 year
* Amenorrheic at least 2 years without a hysterectomy and oophorectomy and a follicle stimulating hormone (FSH) value in the postmenopausal range upon pre-study (screening) evaluation
* Post hysterectomy, bilateral oophorectomy, or tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure, otherwise the subject must be willing to use 2 adequate barrier methods throughout the study, starting with the screening visit through 120 days after the last dose of study therapy.
10. Subject is willing and able to comply with the protocol for the duration of the study including providing medical information, study examinations or tests at scheduled visits and study treatment.
You may not be if
1. Any significant medical condition or laboratory abnormalities which place the subject at unacceptable risk if he/she were to participate in the study at clinician's discretion and not otherwise stated below.
2. For the DAN-222 and niraparib combination cohorts, subjects cannot have known sensitivity to FD\&C Yellow No. 5 (tartrazine).
3. Allergic reaction to irinotecan, topotecan, or govitecan.
4. Concurrent administration or received cytochrome P450 3A4 (CYP3A4) enzyme inducers or inhibitors within 2 weeks prior to the first day of study treatment.
5. Subjects taking medications know to prolong the QT interval or associated with torsades de pointes, unless the subject can safely discontinue these medications or change to comparable medications that do not significantly prolong the QT interval, at least 5 half-lives or 7 days (whichever is longer) prior to the first dose of DAN-222.
6. History of myelodysplasia, or has a known additional malignancy that progressed or required active treatment within the last 3 years. Exceptions include non-melanoma skin cancer and carcinoma in situ.
7. Carcinomatous meningitis.
8. Subject is pregnant or breastfeeding, or expecting to conceive children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of study treatment.
9. Inability to comply with study procedures or unwilling to use adequate birth control.
10. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia that would limit compliance with study requirements.
11. Subject has a heart-rate corrected QT interval (QTc) prolongation \> 470 msec at screening.
12. Any serious social, psychosocial, or medical condition or abnormality in clinical laboratory tests that, in the Investigator's judgment, precludes the subject's safe participation in and through a minimum of 4 cycles of treatment, or which could affect compliance with the protocol or interpretation of results.
