Scientific title | A phase II/III, randomised, two-arm comparison of maintenance lapatinib versus placebo after first-line chemotherapy in patients with HER1 and/or HER2 overexpressing locally advanced or metastatic bladder cancer |
Study acronym | LaMB |
Study objectives | Metastatic bladder cancer is treated with platinum analogue based chemotherapy. In this study patients will initially be treated with standard chemotherapy for locally advanced and metastatic bladder cancer. Those patients who have either a response to treatment (Response Evaluation Criteria in Solid Tumours [RECIST] criteria) or stabilisation of disease will go onto the study. Only those patients who are HER1 and/or HER2 positive will be eligible, as previous studies have shown that these individuals are most likely to respond to treatment with lapatinib. Patients will be randomised to receive maintenance therapy with either lapatinib or placebo. Therapy will continue until disease progression, excessive toxicity or patient request, at which point the treatment will be stopped and patients will be treated according to the doctor's discretion. |
Ethics approval(s) | South East Research Ethics Committee, 28/11/2007, ref: 07/H1102/73 |
Health condition(s) or problem(s) studied | Topic: National Cancer Research Network; Subtopic: Bladder Cancer; Disease: Bladder (advanced) |
Intervention | 1. Lapatinib 2. Placebo Dosage given = 1500 mg (6 x 250 mg tablets) per day. Patients will receive treatment until progression of disease. Follow up is continued at doctor's discretion until death. |
Intervention type | Drug |
Pharmaceutical study type(s) | |
Phase | Phase II/III |
Drug / device / biological / vaccine name(s) | Lapatinib |
Primary outcome measure | Compare progression-free survival (PFS) in patients with HER1 and/or HER2 over expressing stage IV b, measured after the last follow up of the last patient. |
Secondary outcome measures | Measured after the last follow up of the last patient: 1. To compare overall survival (OS) between the two groups 2. Evaluate the safety and tolerability |
