A Phase 1/2 Study Of HKI-272 (Neratinib) in Combination With Trastuzumab (Herceptin) In Subjects With Advanced Breast Cancer

Phase 1
Completed
Conditions
Advanced Breast Cancer
Interventions
Registration Number
NCT00398567
Lead Sponsor
Puma Biotechnology, Inc.
Brief Summary

The purpose of this study is to determine the safety and efficacy of HKI-272 (neratinib) in combination with trastuzumab in patients with advanced breast cancer.

Detailed Description

Open label phase 1/2 study of ascending multiple oral doses of HKI-272 in combination with IV trastuzumab in subjects with advanced human epidermal growth factor receptor 2 positive (HER2+) breast cancer. Three to six subjects will be enrolled in each dose group. Adverse events and dose limiting toxicities will be assessed from the first dose of study drug though day 21. When the maximum tolerated dose (MTD) of HKI-272 plus trastuzumab is determined, an additional 30 subjects will be enrolled at that dose level, and followed for progression free survival for approximately 1 year.

Primary Outcome Measures
NameTimeMethod
16-week Progression-free Survival (PFS) RateFrom first dose date to progression status (PD or death) at 16-week

16-week progression-free survival (PFS) rate for subjects with advanced breast cancer who receive neratinib at the maximum tolerated dose (MTD) in combination with trastuzumab, evaluable population.

Secondary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)From first dose date to progression or last tumor assessment, up to five and a half years.

Percentage of participants with partial response (PR) or complete response (CR) per Response Evaluation Criteria In Solid Tumors Criteria (RECIST) v.1.0: Complete Response (CR), disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; and Non-PD for non-target lesions, and no new lesions.

Duration of Response (DOR)From start date of response to first PD, assessed up to five and half years after the first subject was randomized

Duration of response was measured from the time at which response criteria were met for complete response (CR) or partial response (PR) (whichever status was recorded first) until the first date on which recurrence or PD was objectively documented, taking as the reference for PD the smallest measurements recorded since the test article administration started.

Progression Free Survival (PFS)From first dose date to progression or death, assessed up to five and half years.

Progression Free Survival was measured from the date of the first dose of test article until the first date on which recurrence or progression, or death due to any cause, was documented, censored at the last evaluation, investigator assessment.

Clinical Benefit Rate (CBR)From first dose date to progression or last tumor assessment, assessed up to five and half years.

The percentage of participants with a best overall response of a complete response (CR) or partial response (PR) or stable disease (SD) \>=24 weeks.

Area Under the Curve of Neratinib ConcentrationPrior to the first dose, and at hours 1, 2, 4, 6, 8 and 24 on days 22.

Area Under the Curve of Neratinib concentration at day 22 following Administration of Neratinib 240 mg in combination with Trastuzumab 2 mg/kg in Subjects with Cancer.

Terminal-phase Elimination Half-life of Neratinib in Combination With Trastuzumab.Prior to the first dose, on days 22 through 23 of month 1, and on day 1 in months 2 through 6

Terminal-phase elimination half-life of Neratinib at day 22 following Administration of Neratinib 240 mg in combination with Trastuzumab 2 mg/kg to Subjects with Cancer.
