Summary
This phase II trial will combine two agents, cabazitaxel and lapatinib, to treat patients
with metastatic breast cancer (MBC) which has metastasized to the brain. The first portion
of the study will determine the optimal dose of the cabazitaxel/lapatinib combination to
administer to patients. After determining the optimal dose, patients will continue treatment
with cabazitaxel and lapatinib to assess response to treatment with these agents.
Clinical Details
Official title: Phase II Study With Lead-in Safety Cohort of Cabazitaxel Plus Lapatinib as Therapy for HER2-Positive Metastatic Breast Cancer Patients With Intracranial Metastases
Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Primary outcome: Objective Response RateNumber of patients with grade 3/4 adverse events as a measure of safety and tolerability.
Secondary outcome: Clinical Benefit RateProgression Free Survival Extra-cranial response rate
Detailed description:
This is an open-label, non-randomized, Phase II study with a lead-in safety cohort.
Through the safety lead-in portion of this trial we will define the optimal dose of
cabazitaxel when given in combination with lapatinib for patients with HER2-positive MBC and
CNS metastases. The Phase II portion will further assess intracranial response rate in
patients with HER2-positive MBC and CNS metastases. Toxicity and progression free survival
(PFS) will be obtained and evaluated. The trial will be conducted at multiple study sites
by SCRI Development Innovations.

cm in the longest dimension), on T1 weighted, gadolinium enhanced MRI. Patients may
have had surgical excisions of brain metastases provided at least one lesions meets
the following criteria:
- Patients with brain metastases previously untreated with any intra-cranial
radiation (i. e. no whole brain radiation therapy [WBRT]/partial brain radiation
or stereotactic radiosurgery [SRS]) must have at least one intra-cranial tumor
lesion that is ≥ 5mm.
- Patients with brain metastases previously untreated with any intracranial
radiation (i. e., no whole brain radiation therapy [WBRT]/partial brain radiation
or stereotactic radiosurgery [SRS]) must have at least one intracranial tumor
lesion that is ≥ 5mm.
- Patients with brain metastases previously treated with WBRT/partial brain
radiation only must have at least one intracranial tumor lesion ≥ 5mm and must
have evidence of intracranial progressive disease
- Patients previously treated with WBRT/partial brain radiation and SRS must have
at least one intracranial tumor lesion ≥ 5mm that was not treated with SRS and
must have intracranial disease.
- Patients previously treated with SRS must either demonstrate disease progression
≥ 12 weeks after completing SRS with a lesion measuring ≥ 5mm or must have at
least one intracranial tumor lesion ≥ 5mm that was not treated with SRS.
4. Patients who have received WBRT/partial brain radiation for intra-cranial metastases
are eligible if treatment was completed ≥28 days prior to the first dose of study
drug.
5. Estrogen receptor (ER) and progesterone receptor (PR) status in the primary or most
recent tumor assessment must be known or pending at the time of study registration.
Patient's ER/PR status (i. e., positive or negative) does not influence enrollment but
is a requirement.
6. Patient must have received prior treatment with HER2-directed therapy such as
trastuzumab, either in the adjuvant or metastatic setting.
7. Prior treatment with lapatinib in the (neo)adjuvant and metastatic setting.
8. Patients without prior chemotherapy for MBC are eligible provided the patients
relapsed during adjuvant therapy with trastuzumab or ≤6 months following completion
of adjuvant therapy. Otherwise, there is no specific minimum or maximum number of
previous chemotherapy regimens for MBC.
9. Patients must have completed cytotoxic chemotherapy ≥21 days (for an every 3-week
regimen) or ≥14 days (for an every 2-week or weekly regimen) and have recovered from
or come to a new chronic or stable baseline from all treatment-related toxicities in
order to be eligible for study treatment.
- Patient must have completed biologic therapy ≥3 weeks or 5-half lives whichever
is shorter.
- Patient must be discontinued from hormonal therapy a minimum of 1 day prior to
the first dose of study treatment.
- Patients receiving palliative radiation to bone, soft tissue or any other
disease sites must have completed this ≥1 week prior to the first dose of study
treatment.
10. Patients must have recovered (>2 week recovery is mandated) from any acute
neurosurgical intervention for metastatic CNS disease (e. g., resection, shunt
placement) and must be clinically stable. These patients must have residual
measurable CNS lesion(s) following the surgical procedure if this site is to serve as
the target lesion.
11. Patients must be neurologically stable, and if receiving steroids, must be on stable
or decreasing doses of corticosteroids and/or anticonvulsants for defined as being on
stable low doses of corticosteroids ≥ 5 days prior to the first dose of study
treatment.

13. Adequate hematologic, renal, and hepatic function.
14. Adequate coagulation parameters.
15. Other laboratory testing:
- Serum magnesium ≥ the institutional lower limit of normal (LLN)
- Serum potassium ≥ the institutional LLN
16. Male patients willing to use adequate contraceptive measures.
17. Female patients who are not of child-bearing potential, and female patients of
child-bearing potential who agree to use adequate contraceptive measures, who are not

C (HCV).
10. Presence of other active cancers, or history of treatment for invasive cancer ≥3
