Brief Summary

This is a Phase I, open-label, dose escalation study. MSI-1436 will be administered as a single intravenous infusion twice a week for 3 weeks on a 4-week cycle.

Detailed Description

This is a Phase I, open-label, dose escalation study. MSI-1436 will be administered as a single intravenous infusion twice a week for 3 weeks on a 4-week cycle. Subjects will be enrolled according to a standard Phase I Fibonacci design to receive MSI-1436. Drug infusions will last approximately 2 hours. If a subject has a dose-limiting toxicity (DLT) at any time during the study, MSI-1436 will be held and either re-started or discontinued in that subject as per the Dose Adjustments and Toxicities Guidelines.

Inclusion Criteria
  • Signed, witnessed, and dated Institutional Review Board (IRB) approved Informed Consent Form (ICF).
  • Pathologically confirmed metastatic breast cancer with measurable disease. Metastatic sites must be measurable on CT, MRI, or FDG-PET/CT as per the revised RECIST v1.1 criteria or measurable disease on physical examination.

  • Stable brain metastasis is permitted. This is not considered measurable disease.

Stable brain metastasis is defined as no change on CT scan or MRI for minimum of 2 months AND no change in steroid dose for a minimum of 4 weeks

  • A negative serum pregnancy test, if female of reproductive potential. Reproductive potential defined as age < 55 or with no menses for < 1 year
  • Screening laboratory values as follows:

Total bilirubin ≤1.5 times upper limit of normal (ULN). Aspartate aminotransferase (serum glutamic oxaloacetic transaminase) and alanine aminotransferase (serum glutamic pyruvate transaminase)≤ 2.5 times ULN.

Serum creatinine ≤2.0 mg/dL or calculated creatinine clearance ≥60 mL/min. Absolute neutrophil count >1,500 cells/mm3. Platelet count ≥100,000 plt/mm3. Hemoglobin ≥ 8 g/dL. Non-diabetic

Exclusion Criteria
  • Pregnant or breast-feeding

Primary Outcome Measures
NameTimeMethod
Maximally Tolerated Dose (MTD) of MSI-1436one year

Subjects will be enrolled according to a standard Phase I Fibonacci design to receive MSI-1436C. If a subject has a dose-limiting toxicity (DLT) at any time during the study, MSI-1436C will be held and either re-started or discontinued in that subject as per the Dose Adjustments and Toxicities Guidelines.

Secondary Outcome Measures
NameTimeMethod
Peak plasma concentration of the drug after administration (cmax)one year

The maximum (or peak) serum concentration that MSI-1436C achieves in the plasma after the drug has been administrated and prior to the administration of a second dose.

Area under the plasma concentration versus time curve (AUC)one year

The area under the plasma drug concentration-time curve (AUC) reflects the actual body exposure to drug after administration of a dose of MSI-1436C.

Number of participants with treatment-related adverse events as assessed by CTCAE v4.0one year

All adverse events and dose-limiting toxicities will be recorded and tabulated. A dose-limiting toxicity (DLT) will be defined as any grade 3 or higher NCI Common Toxicity Criteria adverse event (CTCAE) that is deemed related to the study drug MSI-1436C, any infusion reaction necessitating drug discontinuation, or any other drug related adverse event leading to the study drug discontinuation.

Descriptive statistics will be used to summarize adverse events and dose-limiting toxicities. The proportion of AEs and DLTs will be calculated along with their corresponding exact 95% confidence intervals.

Time required for the concentration of MSI-1436C to reach half of its original value, or half life (t1/2)one year

The time required for the concentration of MSI-1436C to reach half of its original value.

Time to reach cmaxone year

The amount of time for MSI-1436C to reach Cmax

response ratesone year

To assess the response rates of MSI-1436C in metastatic breast cancer patients the outcome variable of interest is time-to-progression. Patients who have not progressed (or who have not died) as of their last known follow-up, will be considered 'censored' for the time-to-progression analysis.

Time-to-progression will be estimated using the Kaplan-Meier Product-Limit Method. Any post- hoc group comparisons will be carried out using the log-rank test. Patients who have not progressed (or who have not died) as of their last known follow-up, will be considered 'censored' for the time-to-progression analysis.
