NCT ID: NCT01306942

Last Updated: 2023-03-30

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 37 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2011-07-31
• Study Completion Date: 2019-03-15

Brief Summary

This is a single-arm, open-label, phase I/II study. In the phase I, patients with Human Epidermal Growth Factor Receptor 2 (HER2) positive MBC will be treated with paclitaxel, trastuzumab and increasing doses of dasatinib to determine the Maximum Tolerated Dose (MTD), Dose Limiting Toxicity (DLT) and Recommended Phase II Dose (RPD) of the combination. Once the RPD has been identified, 48 patients will be treated at that dose to evaluate the efficacy and safety of the combination in the phase II.

Detailed Description

Eligible patients will be enrolled and treated with 4-week cycles of trastuzumab 2 mg/kg IV weekly (following a loading dose of 4 mg/kg in cycle 1) and paclitaxel 80 mg/m2 weekly x 3 weeks followed by a rest period of 7 days. Dasatinib will be administered orally in two dose levels 100 and 140 mg once daily (a -1 dose level is included just in case dose de-escalation is needed). Treatment will be repeated on Day 1 of a 28-day cycle in all patients (both in the phase I as in the phase II) until radiographic or symptomatic progression or unacceptable toxicity occurs. Only in the phase I and in all patients included in every different dose level, the first cycle will last 38 days.

Primary Objective:

• To determine the maximum tolerated dose (MTD) and recommended phase II dose (RPD) of dasatinib in combination with fixed doses of trastuzumab and paclitaxel in HER2-positive MBC patients (Phase I).
• To determine the efficacy, measured by objective response rate (ORR) in HER2-positive MBC patients with measurable disease (Phase II).

Secondary Objective(s):

• To characterize the safety of the combination (in both phase I and phase II).
• To evaluate the Clinical Benefit Rate (CBR), Time to Progression (TTP), Progression Free Survival (PFS) and Response Duration (RD) (in the phase II).
• To evaluate the pharmacokinetics (PK) of the combination (in the phase I and selected patients in the phase II if necessary).
• To evaluate molecular characteristics that may be predictive of the activity (or lack of) and any correlation between the biological activity of the study treatment and the disease outcome.

Exploratory objective:

• To explore the correlation between the lymphocytosis and efficacy.

Sample Size:

Phase I: following the 3+3 rule, a minimum of 6 and a maximum of 12 patients will be recruited.

Phase II:Assuming 10% drop-out rate, 48 patients are required to enter the study.

The duration of the study, from first patient visit to last patient visit will be approximately 42 months.

Study Groups

Dasatinib + trastuzumab + paclitaxel

Eligible patients will be enrolled and treated with 4-week cycles of trastuzumab 2 mg/kg IV weekly (following a loading dose of 4 mg/kg in cycle 1) and paclitaxel 80 mg/m2 weekly x 3 weeks followed by a rest period of 7 days. Dasatinib will be administered orally in two dose levels 100 and 140 mg once daily (QD) (a -1 dose level is included just in case dose de-escalation is needed). Treatment will be repeated on Day 1 of a 28-day cycle until radiographic or symptomatic progression or unacceptable toxicity occurs. Only in the phase I, the first cycle will last 38 days.

Eligibility Criteria

Inclusion Criteria

1. Female with histologically confirmed breast cancer with documented metastasis.

2. Patients must have Human Epidermal Growth Factor Receptor 2 (HER2) overexpression by immunohistochemistry (3+, HercepTest®; DAKO) or a positive fluorescence in situ hybridization for HER2 amplification evaluated by central laboratory. It is recommended that a formalin-fixed paraffin embedded (FFPE) tumor tissue block from the metastatic site (or the primary tumor, if metastatic site not available) required for HER2 testing are provided.

3. Patients can have measurable or non measurable disease for the Phase I part. For the Phase II only patients with measurable disease defined per RECIST 1.1 will be included.

4. Signed Written Informed Consent.

5. Target Population:

1. Patients with Performance Status (ECOG) of 0 or 1.

2. Number of previous therapies allowed or previous therapies may have included:

• Chemotherapy: no prior chemotherapy for MBC is permitted. Patients treated with adjuvant chemotherapy regimens based on taxanes are allowed to be included if they are fully recovered of any taxane associated toxicity and a minimum of 12 months have elapsed from the end of this therapy.
• Hormonal Therapy: patients may have had prior hormonal therapy. All hormonal agents must be discontinued at least 3 weeks prior to study entry.
• Radiation Therapy: patients may have had prior radiation therapy that has not exceeded 25% of the bone marrow reserve. A minimum of 21 days must have elapsed between the last dose of radiation and registration into the study. Patients must have recovered from any acute toxic effects from radiation prior to registration. Lesions that have been irradiated cannot be included as sites of measurable disease for the phase II unless clear tumor progression, according to RECIST criteria, has been documented in these lesions since the end of radiation therapy.
• Previous Surgery: previous surgery is permitted provided that wound healing has occurred.
• Anti-HER2 Therapies: no prior anti-HER2 therapy for MBC is permitted. Patients treated with adjuvant anti-HER2 therapies (including but not limited to trastuzumab and lapatinib) are allowed to be included if a minimum of 12 months have elapsed from the end of this therapy.
