Condition(s) targeted: Neoplasms, Breast

Intervention: lapatinib (Drug)

Phase: Phase 2

Status: Completed

Sponsored by: GlaxoSmithKline

GSK Clinical Trials, Study Director, Affiliation: GlaxoSmithKline

Summary

This study was designed to determine how effective and safe a new investigational drug, lapatinib, is in treating patients with treatment refractory or relapsed inflammatory breast cancer. Tumor tissue collected pre-treatment and at Day 28 will be examined for biologic activity by IHC (immunohistochemistry). Treatment will consist of daily oral therapy with lapatinib. A patient may continue treatment as long as they are receiving benefit. Blood samples for hematology and chemistry panels, MUGA/ECHO (multigated acquisition/echocardiogram) exams and physical exams will be performed throughout the study to monitor safety.

Clinical Details

Official title: A Phase II Study to Evaluate the Efficacy, Safety and Pharmacodynamics of Lapatinib in Patients With Relapsed or Refractory Inflammatory Breast Cancer

Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Objective Response rate (complete response plus partial response)

Secondary outcome:

Clinical benefit (progression free survival, time to progression, response duration)

Assessment of clinical benefit, defined as CR or PR for at least 4 weeks, or SD for at least 6 months

Calculation of progression-free survival, defined as the time between the first dose of investigational product and the first documented sign of disease progression or death.

Calculation of time-to-response, defined as the time between the first dose of investigational product and the first documented CR or PR.

Calculation of duration of response, defined as the time from initial documented CR or PR to the first documented sign of disease progression.

Evaluation of changes in QoL and pain scale measurements collected on Day 1 and every 4 weeks while receiving study treatment.

Evaluation of adverse events (AEs), changes in laboratory values and echocardiogram (ECHO) or multiple gated acquisition scan (MUGA) results from pre-dose, during dosing and post-dose assessments

Comparison of the effects of lapatinib on biomarkers that are involved in regulating tumor cell proliferation and survival (e.g., phosphorylated forms of Erk1/2 and Akt, STAT3, S6 Kinase, Bad, truncated ErbB2 and potentially other downstream mediators of

tumor cell growth and survival) by quantitative IHC and by direct and genome-wide methods (e.g., direct sequencing and DNA microarray) in tumor tissue collected prior to and following 28 days of lapatinib monotherapy.

Examination of the effects of lapatinib therapy on the levels of circulating ErbB1 and ErbB2 ECD and the proteomic profile of peripheral blood. Investigation of the use of FDG-PET to predict early response to treatment with lapatinib.

Detailed description: This Phase II open label, multicenter study is designed to evaluate the efficacy, safety, and pharmacodynamic effects of oral lapatinib administered as a single agent therapy to patients with relapsed or refractory inflammatory breast cancer. Eligible patients must have a diagnosis of inflammatory breast cancer based on clinicopathologic criteria, tumor that is readily accessible for biopsy, and must have previously received treatment with an anthracycline and taxane-containing regimen (30 patients) plus trastuzumab (90 patients). Patients enrolled must have tumors that overexpress ErbB2, with or without co-expression of ErbB1. The primary objective for this study is to evaluate the objective response rate (defined as complete response plus partial response). Secondary objectives are to evaluate clinical benefit including quality of life parameters, progression-free survival, overall survival, time-to-response, response duration, safety and tolerability, pharmacodynamic effects on intracellular mediators that regulate tumor cell growth and survival, as well as effects on proteomic profile, and circulating levels of extracellular domains of ErbB1 and ErbB2 in peripheral blood.

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion criteria:

- Must have a life expectancy of at least 12 weeks.

- Has a left ventricular ejection fraction (LVEF) ≥ 50%, or ≥ lower limit of normal for

the institution, based on ECHO or MUGA.

- Aspartate and alanine transaminase (AST or ALT) ≤ 3 times the upper limit of the

reference range (patients with liver metastases may have AST and ALT ≤ 5 times the upper limit of the reference range and may be enrolled).

- Total bilirubin ≤ 3. 0 mg/dL.

- Serum creatinine ≤ 2. 0 mg/dL or calculated creatinine clearance (CrCl) ≥ 30 mL/min

- Adequate bone marrow function. Hemoglobin ≥ 9 gm/dL. Absolute granulocyte count ≥

1,500/mm³ (1. 5 x 10^9/L). Platelets ≥ 75,000/mm³ (100 x 10^9/L).

- Recovered or stabilized sufficiently from side effects associated with previous

chemotherapy, surgery or radiotherapy.

- Provided written informed consent.

- ECOG (Eastern Cooperative Oncology Group) performance status 0 to 2.

- Able to swallow and retain oral medication.

- Male or female, if female:

A female is eligible to enter and participate in the study if she is of: 1. Non-childbearing potential (i. e., women with functioning ovaries who have a current documented tubal ligation or hysterectomy, or women who are postmenopausal); or 2. Childbearing potential (i. e., women with functioning ovaries and no documented impairment of oviductal or uterine function that would cause sterility. This category includes women with oligomenorrhoea (severe), women who are perimenopausal, and young women who have begun to menstruate), has a negative serum pregnancy test at screening, and agrees to one of the following where considered acceptable to the local IRB/IEC: Double-barrier contraception (condom with spermicidal jelly, foam suppository, or film; diaphragm with spermicide; or male condom and diaphragm). Abstinence from sexual intercourse from 2 weeks prior to administration of the investigational product, throughout the active study treatment period, and through the post-treatment follow-up visit (to occur 28 days after last dose of investigational product). Male partner who is sterile prior to the female subject's entry into the study and is the sole sexual partner for that female subject. Implants of levonorgestrel. Injectable progestogen. Any intrauterine device (IUD) with a documented failure rate of less than 1% per year. Oral contraceptives (either combined or progestogen only). Barrier methods including diaphragm or condom with a spermicide.

- At least 18 years of age.

- Has either measurable disease by Response Evaluation Criteria in Solid Tumors

(RESIST) or clinically evaluable skin disease. Measurable lesions may be in the field of prior adjuvant irradiation; however, there must be at least an 8 week period between the last radiation treatment and the baseline scan documenting disease status for the lesion to be measurable.

- Tumor that is accessible for biopsy.

- Tumor that overexpresses ErbB2 defined as 3+ by IHC or FISH +. The ErbB 2

overexpression must be documented prior to dosing.

contained a taxane and anthracycline-containing regimen in the adjuvant or metastatic setting (30 patients) plus trastuzumab (90 patients)

the presence of inflammatory changes in the involved breast, including diffuse erythema and edema (peau d'orange), with or without an underlying palpable mass involving the majority of the skin of the breast. Pathologic evidence of dermal lymphatic invasion should be noted but is not required for diagnosis. Exclusion criteria:

- Is clinically assessed to have inadequate venous access for protocol-related blood

draws.

- Has Class II to IV heart failure as defined by the New York Heart Association (NYHA)

functional classification system.

- Has physiological, familial, sociological, or geographical conditions that do not

permit compliance with the protocol.
