Trial overview

Official title: LPT 111111- A Single-arm, Multicenter Phase II Study to Evaluate The Combination of Weekly Nanoparticle Albumin bound Paclitaxel (nab-Paclitaxel or ABRAXANE®) and Lapatinib (TYKERB®) in Women With No More Than One Prior Treatment for ErbB2 Overexpressing Metastatic Breast Cancer
Trial description: This is an open-label, single-arm, multi-center, Phase II study to determine the activity of nab-paclitaxel plus lapatinib in the first and second-line setting in women with ErbB2 overexpressing metastatic breast cancer (MBC). Sixty subjects will be enrolled in the study. Subjects will receive nab-paclitaxel (100 mg/m2 intravenously once weekly for 3 weeks, followed by a rest week in a 4-week cycle) plus lapatinib (1000 mg once daily). Subjects will receive treatment until disease progression or withdrawal from the study. The primary objective of this study is to evaluate overall tumor response rate of lapatinib in combination with nab-paclitaxel administered in women with ErbB2 overexpressing MBC who have received no chemotherapeutic regimen in the metastatic setting. Secondary objectives include progression-free survival, overall survival, duration of response, time to response and time to progression and safety. Safety and efficacy assessments will be performed at 8 and 12 week intervals, and at the end of treatment.

    • A subject will be eligible for inclusion in this study only if all of the following criteria apply:
    • Subjects must have histologically confirmed invasive breast cancer with Stage IV disease at primary diagnosis or at relapse after curative-intent surgery. Where the disease is restricted to a solitary lesion, the neoplastic nature of the lesion should be confirmed by cytology or histology.

    Inclusion and exclusion criteria
    Inclusion criteria:
    • A subject will be eligible for inclusion in this study only if all of the following criteria apply:
    • Subjects must have histologically confirmed invasive breast cancer with Stage IV disease at primary diagnosis or at relapse after curative-intent surgery. Where the disease is restricted to a solitary lesion, the neoplastic nature of the lesion should be confirmed by cytology or histology.
    • Documented amplification of ErbB2 3+ by immunohistochemistry or a positive score (>2.2) by FISH using a local laboratory result (which will be considered sufficient in this study with no further verification by a central laboratory).
    • Subjects must have received no more than one prior chemotherapeutic regimen in the metastatic setting.
    • If a taxane had been administered in the neoadjuvant, adjuvant or metastatic setting, progression must have occurred ≥12 months after completion of this treatment.
    • Prior therapy with radiation for this breast cancer population is permitted if it was administered in the neoadjuvant or adjuvant non metastatic setting. Radiotherapy given in the metastatic setting, prior to initiation of study medication, is allowed to a limited area (e.g., palliative therapy and involving less than 25% of bone marrow), if it is not the sole site of disease. Subjects must have completed radiation treatment and recovered from all acute radiation treatment related toxicities (e.g., bone marrow suppression) prior to commencement of combination treatment.
    • The subject must have received all prior chemotherapy treatment at least 4 weeks prior to enrollment in this study and must have recovered from all related toxicities. Subjects who have received weekly dose of prior chemotherapy e.g. gemcitabine or capecitabine may enroll 2 to 3 weeks after cessation of treatment provided that they have recovered from all related toxicities.
    • Prior therapy with trastuzumab in the neoadjuvant, adjuvant or metastatic setting is permitted. The subject must have received all prior trastuzumab treatment at least 4 weeks prior to enrollment in this study and must have recovered from all related toxicities.
    • Prior endocrine therapy is permitted in the neoadjuvant or adjuvant or metastatic setting. The subject must have received all prior endocrine treatment at least 1 week prior to enrollment in this study and must have recovered from all related toxicities.
    • Prior diagnosis of cancer is allowed as long as the subject is free of disease for 5 years. Subjects with completely resected basal or squamous cell skin cancer, thyroid cancer or successfully treated cervical carcinoma in-situ will be allowed if it has been 1 year or greater since definitive surgery.
    • Subjects must have measurable disease, according to Response Evaluation Criteria in Solid Tumors (RECIST) guidelines; defined as at least 1 lesion that can be accurately measured in at least 1 dimension (longest diameter [LD] to be recorded) by mammogram, ultrasound or physical exam [Therasse, 2000].
