Filter by:This study will characterize the effect of elevated gastric pH mediated by the proton-pump inhibitor, esomeprazole, on the relative bioavailability of lapatinib in subjects with metastatic ErbB2 positive breast cancer.
This study will be a randomized 3-treatment, cross-over study to evaluate the bioavailability of lapatinib administered after a high or low-fat meal.
This study is designed to provide continued access to lapatinib as monotherapy or as part of a combination regimen to cancer subjects who are currently participating in a phase I trial that has met its study objectives.
This is an open-label, four-arm, Phase I, dose escalation study to evaluate the safety and tolerability and to determine the optimal tolerated regimen (OTR) of pazopanib in combination with epirubicin or doxorubicin in patients with advanced solid tumors. Patients will be enrolled in cohorts of 3 to receive escalating doses of pazopanib and epirubicin or doxorubicin. Dose escalation schemas for each study arm are described in the protocol. For each arm, the OTR will be defined as the highest dose combination of the agents where no more than one out of six patients experiences a dose-limiting toxicity. Twelve additional patients in each arm will be studied with the OTR to evaluate toxicity and pharmacokinetics. This will allow an assessment of potential drug-drug interactions. Antitumor activity will be assessed using RECIST criteria.
This was 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 were to be enrolled in the study. Subjects were to 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 were to receive treatment until disease progression or withdrawal from the study. The primary objective of this study was to evaluate overall tumor response rate of lapatinib in combination with nab-paclitaxel administered in women with ErbB2 overexpressing MBC who received no chemotherapeutic regimen in the metastatic setting. Secondary objectives included progression-free survival, overall survival, duration of response, time to response and time to progression and safety. Safety and efficacy assessments were to be performed at 8 and 12 week intervals, and at the end of treatment. Subject: Metastatic Breast Cancer, ErbB2, First-line therapy, Lapatinib, Nab-paclitaxel
This is a two part study looking at the effect of lapatinib on concentrations of digoxin in the blood when both drugs are dosed together in Part 1; and looking at the safety and antitumor effect of lapatinib when used together with possible additional anticancer therapy as chosen at the doctor's discretion.
The double blind part of the study is being conducted to compare the efficacy and safety of pazopanib in combination with lapatinib with that of lapatinib alone in subjects with inflammatory breast cancer whose tumors overexpress the ErbB2 protein. There is also an Open-label pazopanib arm to this study designed to test whether pazopanib given alone and lapatinib given alone would be safe and effective to treat patients with inflammatory breast cancer.
This is a randomised, open label multicenter Phase III study comparing the efficacy of neoadjuvant lapatinib plus paclitaxel, versus trastuzumab plus paclitaxel, versus concomitant lapatinib and trastuzumab plus paclitaxel given as neoadjuvant treatment in HER2/ErbB2 over-expressing and/or amplified primary breast cancer. Patients will be randomised to receive either: lapatinib 1500 mg daily, trastuzumab 4 mg/kg intravenous (IV) load followed by 2 mg/kg IV weekly, or lapatinib 1000 mg daily with trastuzumab 4 mg/kg IV load followed by 2 mg/kg IV weekly for a total of 6 weeks. After this biological window, patients on monotherapy arms will continue on the same targeted therapy plus weekly paclitaxel 80 mg/m^2 for a further 12 weeks, up to definitive surgery. In the combination arm, patients will receive lapatinib 750 mg daily in combination with trastuzumab 2 mg/kg IV plus weekly paclitaxel 80mg/m^2 IV for a further 12 weeks, up to definitive surgery. After surgery, patients will receive three courses of adjuvant chemotherapy with 5-Fluorouracil Epirubicin Cyclophosphamide (FEC) followed by the same targeted therapy as in the biological window of the neoadjuvant setting for a further 34 weeks (in the combination arm, lapatinib dose will be 1000 mg daily in combination with trastuzumab). The planned total duration of the anti-HER2 therapy one year. Primary objective is to evaluate and compare the rate of pathological complete response (pCR) at the time of surgery in patients with HER2/ErbB2 overexpressing or amplified operable breast cancer randomised to lapatinib followed by lapatinib plus paclitaxel versus trastuzumab followed by trastuzumab plus paclitaxel versus lapatinib in combination with trastuzumab followed by lapatinib, trastuzumab plus paclitaxel.
This is a randomised, open label multi-centre phase III study comparing the activity of lapatinib alone versus trastuzumab alone versus trastuzumab followed by lapatinib versus lapatinib concomitantly with trastuzumab in the adjuvant treatment of patients with ErbB2 overexpressing and/or amplified breast cancer. Patients will be enrolled according to one of two design schemas, with Design 2 having two chemotherapy options (Design 2 and 2B), and will be randomised to one of four treatment regimens within each design schema. The primary objective of this study is to compare disease-free survival (DFS) in patients with HER2 overexpressing and/or amplified breast cancer randomised to trastuzumab for one year versus lapatinib for one year versus trastuzumab (12 or 18 weeks, according to assigned design) followed by a six-week treatment-free interval followed by lapatinib (28 or 34 weeks, according to assigned design) versus trastuzumab in combination with lapatinib for one year (52 weeks). Secondary objectives include treatment comparisons with respect to overall survival, time to recurrence, time to distant recurrence, safety and tolerability, incidence of brain metastasis, and analyses conducted separately for cohorts of patients defined by presence or absence of cMyc oncogene amplification, expression level of PTEN and presence or absence of the p95HER2 receptor. On August 18, 2011, the ALTTO Independent Data Monitoring Committee (IDMC) met to review the first planned interim analysis. The IDMC reported that the comparison of lapatinib alone versus trastuzumab alone crossed the futility boundary, indicating that the lapatinib alone arm was unlikely to meet the pre-specified criteria to demonstrate non-inferiority to trastuzumab alone with respect to disease-free survival (DFS). The IDMC also stated that the other three arms (trastuzumab alone, sequential trastuzumab/lapatinib arm and the combination arm) should continue as planned with no changes.
This study is to evaluate the safety and efficacy of lapatinib taken together with capecitabine in Japanese patients. The study will proceed in two phases; the first phase(Part1) will lead to an evaluation of the mainly tolerability as well as PK parameters. If there are no major safety concerns in Part 1, the study will move into the second phase (Part 2) to further evaluate the safety and clinical activity.
