Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
U3-1287 with trastuzumab + paclitaxel (Phase 1b)
The Phase 1b portion is an open label, dose de escalation, single arm study designed to assess the safety and tolerability of up to 3 dose levels of U3- 1287 in combination with trastuzumab plus paclitaxel and will determine the recommended Phase 2 dose (RP2D) of U3 1287. The first cohort will receive U3- 1287 18 mg/kg intravenously (IV) in combination with trastuzumab plus paclitaxel once every 3 weeks (q3w).
U3-1287
U3-1287: 18 mg/kg administered intravenously once every three weeks
Trastuzumab
Trastuzumab: 6 mg/kg up to 8 mg/kg administered intravenously once every three weeks
Paclitaxel
Paclitaxel: 175 mg/m\^2 administered intravenously once every three weeks
U3-1287 with trastuzumab+paclitaxel (Ph 2)
The Phase 2 portion is a randomized, 2 arm, placebo controlled, double blind study designed to evaluate the safety and the efficacy of U3-1287 at the recommended phase 2 in combination with trastuzumab plus paclitaxel (experimental arm) relative to the control arm (trastuzumab plus paclitaxel and placebo).
U3-1287
The maximum tolerated dose as determined in Phase 1b portion (between 9 mg/kg and 18 mg/kg) administered intravenously once every three weeks
Trastuzumab
Trastuzumab: 6 mg/kg up to 8 mg/kg administered intravenously once every three weeks
Paclitaxel
Paclitaxel: 175 mg/m\^2 administered intravenously once every three weeks
Placebo with trastuzumab+paclitaxel (Ph 2)
The Phase 2 portion is a randomized, 2 arm, placebo controlled, double blind study designed to evaluate the safety and the efficacy of U3-1287 at the recommended phase 2 dose in combination with trastuzumab plus paclitaxel (experimental arm) relative to the control arm (trastuzumab plus paclitaxel and placebo).
Trastuzumab
Trastuzumab: 6 mg/kg up to 8 mg/kg administered intravenously once every three weeks
Paclitaxel
Paclitaxel: 175 mg/m\^2 administered intravenously once every three weeks
Placebo
Placebo: Dose corresponding to U3-1287 administered intravenously once every three weeks

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
1. Women ≥ 18 years old.
2. Histologically or cytologically confirmed adenocarcinoma of the breast with metastatic disease and at least 1 measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST) guidelines Version 1.1.
3. Documented HER2+ disease as measured by FISH or IHC (3+). See Appendix 17.8 for documentation criteria.
4. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
5. Hematological function, as follows:
* Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
* Platelet count \>100 x 109/L
* Hemoglobin ≥9 g/dL.
6. Renal function, as follows:
\- Calculated creatinine clearance ≥60 mL/min using the modified Cockcroft Gault equation.
7. Hepatic function, as follows:
* AST ≤2.5 x ULN (if liver metastases are present, \< 5 x ULN)
* ALT ≤2.5 x ULN (if liver metastases are present, \< 5 x ULN)
* Alkaline phosphatase ≤ 2.0 x ULN (if bone or liver metastases are present, \< 5 x ULN)
* Bilirubin ≤1.5 x ULN.
8. Prothrombin time (PT) and partial thromboplastin time (PTT) ≤1.5 x ULN.
9. Availability of archived tumor sample or fresh tumor specimen (does not have to be provided by treatment start) to confirm HER2 status and for tumor biomarkers/mutation analysis.
10. Subjects must be postmenopausal (no menstrual period for a minimum of 12 months) or surgically sterile, or must use maximally effective birth control during the period of therapy, and be willing to use contraception for 6 months following the last investigational drug dose and have a negative urine or serum pregnancy test upon entry into this study if subject is of childbearing potential. Partners of subjects must be surgically sterile or willing to use a double barrier contraception method upon enrollment, during the course of the study, and for 6 months after last investigational drug dose received.
11. Subjects must be willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
12. Subjects must be competent and able to comprehend, sign, and date an IEC- or IRB-approved ICF before performance of any study specific procedures or tests.
Exclusion Criteria
1. Prior treatment for metastatic disease other than radiation therapy. Neoadjuvant/adjuvant therapy with paclitaxel, and/or docetaxel, and/or trastuzumab is allowed if completed more than 12 months prior to relapse/progression.
2. Clinically active brain metastases, defined as untreated symptomatic, or requiring therapy with steroids or anticonvulsants to control associated symptoms.
