Study of Cipatinib in Patients With HER2 Positive or Uncertain Advanced Breast Cancer
Study Details
Study Description
Brief Summary
Cipatinib is an oral tyrosine kinase inhibitor targeting both HER-1 and HER-2 receptors. This study is designed to evaluate the safety and tolerability of cipatinib in patients with HER2 positive or uncertain advanced breast cancer:
-
To evaluate the safety and tolerability of cipatinib, and the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT)
-
To determine the pharmacokinetic profile of cipatinib and its metabolites
-
To assess preliminary antitumor activity
-
To determine preliminary regimen for phase II study
-
To determine the relation of expression of HER-1 and HER-2 to the antitumor activity.

|---|---|
| Experimental: Cipatinib Each subject will receive a single dose of cipatinib on treatment day 1, followed by 4-day observation period, and then will receive cipatinib once daily in cycles consisting of 21 days. |
Drug: Cipatinib
Cipatinib either at 200, 400, 800, 1200, 1400, 1600 or 1800 mg, p.o. once daily

Outcome Measures
Primary Outcome Measures
- The maximum-tolerated dose (MTD) regimen of cipatinib will be defined as the maximum dose level at which no more than one subject out of six experiences a dose-limiting toxicity (DLT) after completing one treatment cycle. [3 weeks]
Secondary Outcome Measures
- Number of participants with adverse events. [6 weeks]
- Cipatinib pharmacokinetic parameters may include AUC, Cmax, Tmax, and t1/2. [3 weeks]
- Objective response rate (ORR). [6 weeks]
