Urinary bladder cancer is an attractive target for immunostimulating gene therapy because it is sensitive for immunotherapy as demonstrated by the life-prolonging effect of bacillus Calmette-Guérin (BCG) instillations. Phase I: Patients with infiltrative cancer of the urinary bladder and scheduled for cystectomy. Phase IIa: Patients with non-infiltrative cancer of the urinary bladder, stages Ta and scheduled for resection

|---|---|
| Main Objective: Part I To evaluate the feasibility of local treatment of bladder cancer at two dose levels and, if possible, establish the Maximum Tolerable Dose (MTD) by studying the tolerance and toxicity in patients scheduled for cystectomy, during and after repeated instillations of Clorpactin and AdCD40L in the urinary bladder. Part IIa Confirm tolerance/toxicity of repeated instillations of Clorpactin and AdCD40L at the highest dose OR the next lower dose to MTD, in the urinary bladder of patients with marker tumour.;Secondary Objective: Part I - Establish the AdCD40L dose that demonstrates transgene (CD40L) expression in the bladder wall - Assure that there is no systemic exposure toAdCD40L. - Elimination time of AdCD40L in urine post treatment - Change of the immune profile due to virus vector exposure and transgene expression - Tumour response - Establish the baseline symptoms of Clorpactin installation during run-in - Biological activity Part IIa - Tumour response - Investigate the transgene (CD40L) expression in the bladder wall - Assure that there is no systemic exposure toAdCD40L - Elimination time of AdCD40L in urine post treatment - Change of the immune profile due to virus vector exposure and transgene expression - Biological activity ;Primary end point(s): - Registration of the safety profile such as local inflammation, fever, pain, change in blood pressure, pulse and other adverse events. | — |
