Brief Summary

Modification of the EGF signalling pathway and / or HER 2, by Lapatinib in bladder cancer.

Detailed Description

Patients with invasive bladder tumor , candidates for radical cystectomy. Patients will receive Lapatinib during 3 weeks +/- 5 days, before cystectomy. A comparison of tissue from the original biopsy and cystectomy after Lapatinib will allow this to occur.

TREATMENT AND STRATEGY Lapatinib in bladder carcinoma -Overall there are arguments for considering that egf pathway is involved in bladder carcinoma and so far that drugs inhibiting EGF pathway could have an impact for therapeutical endpoints.

Nevertheless it is unclear that from previous studies that adding egf inhibiting drug to chemotherapy is clinically relevant, essentially by difficulties to measure a beneficial endpoint while downstream EGF pathways have been modified by these drugs, as shown with lapatinib (see 2.1.5).

Furthermore, there is no argument for initial selection of patients based on the initial egfr and/or her 2 tumor profile, asking for more intense knowledge.

LAPATINIB TREATMENT Patients will receive lapatinib therapy at a daily standard dose of 1500 mg.

LAPATINIB TREATMENT DURATION Patients will then receive 3 weeks of lapatinib therapy + possible 5 days. As the study is a non direct benefit study, the exposition to the drug is proposed during the standard window of 3 to 4 weeks to organize a radical cystectomy in patients with muscle invasive bladder carcinoma. In this study patients, the standard procedure is not delayed for the purpose of the study.

The duration of exposition to lapatinib as to be long enough to have a continuous impact of biological events to induce indeed inhibition of EGF pathway but also to impact on more complex or more distal events as apoptosis and so to be able to measure it. This justifies a 3 weeks of treatment + possible up to 5 days more due to surgical organization procedures.

Surgery will take place on the last day of treatment, which is recommended due to the half-life of lapatinib. Nevertheless for surgical purpose, the drug could be not given on the day of surgery.

This category includes women with oligomenorrhoea (even severe), women who are perimenopausal and young women who have begun to menstruate), who have a negative serum pregnancy test at screening, and agree to one of the following consistent and correct use of one acceptable methods of birth control : Any intrauterine device (IUD) with a documented failure rate of less than 1% per year, or combined oral contraception
• care must be taken to avoid pregnancy in partners of male patients.
• Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures.
• Affiliated or profit patient of a social security system

Exclusion Criteria

• Prior pelvic radiation or neoadjuvant chemotherapy.
• Pregnancy or breastfeeding.
• Other severe acute or chronic medical or psychiatric condition that would impart, in the judgment of the investigator, excess risk associated with study participation or study drug administration, or which, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
• Patients with significantly reduced LVEF or LVEF < 50%.
• Patient with any of the following liver abnormal laboratory test :
• Serum bilirubin > 1,5 x upper limit of normal (ULN) (in case of Gilbert syndrome, a higher serum total bilirubin (< 2 ULN) is allowed
• Alanine amino transferase (ALAT) or aspartate amino transferase (ASAT) > 2,5 ULN
• Platelets <100 x 109/L, hemoglobin < 9 g/dl, absolute neutrophil count (ANC) <1.5 x 109/L
• Have current active hepatic or biliary disease (with exception of patients with Gilbert's syndrome, asymptomatic gallstones, liver metastases or stable chronic liver disease per investigator assessment)
• Serum creatinine > 1.5 x ULN.
• Previous therapy targeting EGFR or HER-2.

• Malabsorption syndrome, disease significantly affecting gastrointestinal function, or major resection of the stomach or bowel, that could affect absorption of lapatinib.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to lapatinib
• Uncontrolled inter-current illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, that would limit compliance with study requirements.
