We conducted a phase I trial to determine the feasible dose for lapatinib, a dual HER2/EGFR tyrosine kinase inhibitor, with paclitaxel and gemcitabine as a neoadjuvant treatment in HER2 positive patients. In this phase I dose-escalation study, cohorts of 3-6 HER2-positive operable breast cancer patients received lapatinib (1,000 mg/day or 1,250 mg/day PO) with paclitaxel (80 mg/m(2)) and gemcitabine (1,000 or 1,200 mg/m(2)) on days 1 and 8 every 21 days to determine the tolerable dosages. Among 13 patients enrolled, 12 (stage III; n = 11: stage II; n = 1) completed treatment and one withdrew consent. The recommended doses were 1000-mg/day lapatinib, 80-mg/m(2) paclitaxel, and 1,000-mg/m(2) gemcitabine. One patient developed dose-limiting grade 3 hepatotoxicity; 3 experienced dose-limiting grade 4 neutropenia. No notable decline in left ventricle ejection fraction occurred. Eight patients achieved clinical partial response and four achieved clinical complete response (CR). Three patients (25%) achieved both tumor and nodal pathologic CR, 5 (42%) achieved tumor pathologic CR, and 6 (50%) underwent breast-conserving surgery. No relationship between lapatinib dose intensity and tumor response was apparent. Median follow-up was 16.2 (range, 6.5-20.7) months. Lapatinib plus paclitaxel and gemcitabine was tolerable with no overlapping toxicity.

Name: Investigational new drugs
Lapatinib is a commonly used drug that interrupts signaling from the epidermal growth factor receptors, EGFR and HER2/neu. Long-term exposure to lapatinib during therapy eliminates cells that are sens...
Imexon is a cyanoaziridine-derived iminopyrrolidone which has synergistic cytotoxicity with gemcitabine. A phase 1 study of the combination demonstrated good tolerance with encouraging clinical activi...
Germ cell tumor patients progressing after high-dose chemotherapy (HDCT) have a dismal prognosis. A prior retrospective study of paclitaxel and gemcitabine enrolled 32 patients. All failed first-line ...
Increasingly, the effectiveness of adjuvant chemotherapy agents for breast cancer has been related to changes in the genomic profile of tumors. We investigated correspondence between growth inhibitory...
The aim of this study was to explore whether a combination of S-1 and paclitaxel offers any benefit over paclitaxel alone to patients pretreated by S-1.
Primary objectives : 1. To evaluate the recommended dose of the combination of paclitaxel, gemcitabine, and lapatinib (Tykerb®) (PGT) as preoperative chemotherapy in patients with HER2 p...
To evaluate the pathologic complete response rate to preoperative administration of Paclitaxel, Gemcitabine, and Trastuzumab (HerceptinÒ) (PGH)
This is an open-label, non-randomized, multi-center study of lapatinib plus paclitaxel to evaluate safety, tolerability and efficacy in Japanese patients with ErbB2 overexpressing advanced...
EGF104578 is two-part study (Pilot part/Randomized part).Pilot part is designed to find the optimal (best) doses of lapatinib and paclitaxel when given together,Randomized part is designed...
This is a phase 1 (the first phase in testing a new drug, to see how safe a new drug or new indication/population ) and phase 2 (the second phase in testing a new drug or new indication/po...
Therapy with two or more separate preparations given for a combined effect.
Colloids with a gaseous dispersing phase and either liquid (fog) or solid (smoke) dispersed phase; used in fumigation or in inhalation therapy; may contain propellant agents.
The interval between two successive CELL DIVISIONS during which the CHROMOSOMES are not individually distinguishable. It is composed of the G phases (G1 PHASE; G0 PHASE; G2 PHASE) and S PHASE (when DNA replication occurs).
Functionalization of exogenous substances to prepare them for conjugation in PHASE II DETOXIFICATION. Phase I enzymes include CYTOCHROME P450 enzymes and some OXIDOREDUCTASES. Excess induction of phase I over phase II detoxification leads to higher levels of FREE RADICALS that can induce CANCER and other cell damage. Induction or antagonism of phase I detoxication is the basis of a number of DRUG INTERACTIONS.
The period of the CELL CYCLE following DNA synthesis (S PHASE) and preceding M PHASE (cell division phase). The CHROMOSOMES are tetraploid in this point.
