Tipifarnib and Fulvestrant in Hormone Receptor-Positive Metastatic Breast Cancer

Detailed Description
PRIMARY OBJECTIVES:
I. To determine the efficacy of tipifarnib (R115777, Zarnestra™) in combination with fulvestrant based on clinical benefit rate (CBR, a combination of complete response rate, partial response rate, and stable disease for more than 24 weeks) in postmenopausal women with hormone receptor-positive metastatic breast cancer who have progressive disease after first-line endocrine therapy.
SECONDARY OBJECTIVES:
I. To determine the median time to progression (TTP) and duration of response of tipifarnib (R115777, Zarnestra™) in combination with fulvestrant in postmenopausal women with hormone receptor-positive metastatic breast cancer.
II. To determine the median overall survival of tipifarnib (R115777, Zarnestra™) in combination with fulvestrant in postmenopausal women with hormone receptor- positive metastatic breast cancer who have progressive disease after first-line endocrine therapy.
III. To determine the toxicity profile of tipifarnib (R115777, Zarnestra™) in combination with fulvestrant versus fulvestrant alone (from historical control) in postmenopausal women with hormone receptor positive metastatic breast cancer who have progressive disease after first-line endocrine therapy.
OUTLINE:
Patients receive fulvestrant intramuscularly on day 1 and oral tipifarnib twice daily on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity*.
NOTE: *Fulvestrant continues even if tipifarnib is held for toxicity.
Patients are followed every 3 months.

Description
Inclusion Criteria:
- Patients must have histologically or cytologically confirmed adenocarcinoma of the breast
- Patients must be postmenopausal
- Patients must have stage IV disease or inoperable locally advanced disease
- Patients must have ER- and/or PR-positive disease as determined by their local pathology laboratory
- Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >= 20 mm with conventional techniques or as >= 10 mm with spiral CT scan; all sites of disease should be noted and followed
- Prior hormonal therapy as adjuvant therapy and/or for metastatic disease is permitted; patients previously treated with two or more prior doses of fulvestrant are not eligible; patients who have received one prior dose of fulvestrant within 28 days are eligible so long as they meet other eligibility criteria
- Patients must have ECOG performance status 0-2 (Karnofsky >= 60%)
- Patients must have life expectancy of greater than 3 months
- Leukocytes >= 3,000/uL
- Absolute neutrophil count >= 1,500/uL
- Platelets >= 100,000/uL
- Total bilirubin =< 2 mg/dL
- AST(SGOT)/ALT(SGPT) =< 2.5 x institutional upper limit of normal
- Creatinine less than or equal to 1.5 times the institutional upper limits of normal
- Patients must be disease-free of prior invasive malignancies for >= 5 years with the exception of: curatively-treated basal cell or squamous cell carcinoma of the skin, carcinoma in situ of the cervix
- Patients must have the ability to understand and the willingness to sign a written informed consent document
- Patients who have had previous therapy with farnesyltransferase inhibitor
Exclusion Criteria:
- Patients who have had radiotherapy within 4 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier; patients who have had prior chemotherapy for metastatic disease are not eligible; prior adjuvant or neoadjuvant chemotherapy is allowed
- Patients may not be receiving any other investigational agents
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to tipifarnib (R115777, Zarnestra™) or other agents used in the study (e.g., imidazoles, quinolones)
- Presence of rapidly progressive, life-threatening metastases; this includes patients with extensive hepatic involvement (> 50% of the liver involved), symptomatic lymphangitic metastases, or brain or leptomeningeal involvement
- Concomitant anticancer treatment with the following exceptions: (1) bisphosphonates for bone metastases, (2) a GnRH analog is permitted if the patient had progressive disease on a GnRH analog plus a SERM or an AI; the GnRH analog may continue but the SERM or AI must be discontinued
- Grade 2 or more peripheral neuropathy
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- HIV-positive patients receiving combination anti-retroviral therapy are excluded from the study because of possible pharmacokinetic interactions with tipifarnib or other agents administered during the study.; appropriate studies will be undertaken in patients receiving combination anti-retroviral therapy when indicated

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Clinical Benefit Rate (CBR) (CR Rate, PR Rate, and SD)
Time Frame: Up to 24 weeks
|
Number of participants met the definition of Clinical Benefit Rate.Tumor response was assessed every three cycles by CT using RECIST (Response Evaluation Criteria In Solid Tumors) criteria.
Per Response Evaluation Criteria in Solid Tumors (RECIST 1.0) for target lesions: Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD; Progressive Disease (PD): At least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter since the treatment started or the appearance of one or more new lesions; Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started.

Up to 24 weeks
